As the saying goes, you can choose when to start a war, but when to end it is not up to you.
This is how the Golden Immortal Liuyun and the Golden Immortal Qingying feel now.
This is also the feeling of the Immortal Lord Guiyi in Heaven.
The attack of tens of thousands of autonomous mechanical aggregates made Guiyi Immortal feel doubled pressure.
Because most of the immortal soldiers had been sent to Mount Buzhou and the Heavenly Palace was empty at this time, facing the attacking autonomous mechanical aggregate, Immortal Master Guiyi could only rush forward in the first place.
Otherwise, the entire heaven’s defense line would easily collapse in the first place.
So, the hundreds of feet long incarnation of Guiyi Immortal Venerable rose from the white jade platform at the first moment, and along with Guiyi Immortal Venerable's real body, it also came to the outside of the Heavenly Palace.
Suddenly, the remaining millions of immortal soldiers and tens of thousands of immortals in heaven cheered.
Everyone firmly believes that as long as Immortal Master Guiyi is there, Heaven will be invincible.
However, this time the number of autonomous mechanical aggregates has increased by hundreds of times, so it will not be as easy to fight them as last time.
Moreover, last time, the autonomous mechanical aggregates were dispersed too much , and more than a hundred autonomous mechanical aggregates split into millions of mechas. The number was too large, so the single defense capability naturally decreased.
This is why the defense of a single mecha is much weaker than the sword of Guiyi Immortal Master, which is why it was destroyed by the sword of Guiyi Immortal Master.
This time, with more autonomous mechanical aggregates, the fight could be fought more easily.
More than a hundred of the tens of thousands of autonomous mechanical aggregates were also divided into millions of mechas to fight against the overwhelming immortal soldiers and immortals.
The remaining autonomous mechanical aggregates were assembled into temporary warships. Some assisted the mechas in besieging the immortal soldiers and immortals, while others directly besieged the Immortal Master Guiyi.
"Come with the sword! Cut!" The incarnation of Guiyi Immortal Master, who was hundreds of feet tall, slashed forward with a sword.
The power of this sword was so great that the dazzling sword light instantly enveloped the entire world, as if a second sun had risen in the sky.
However, the result of this sword was not as useful as Immortal Guiyi had imagined.
A large number of mechas covered by the sword light were damaged, and some temporary warships also had damaged parts, but they did not lose much combat power.
The battleship's main gun continued to bombard Guiyi Immortal Master with great power. The energy around Guiyi Immortal Master was shaking, as if it would completely dissipate in the next moment, exposing him directly to the bombardment of the main gun.
But it doesn’t matter. If one sword is not enough, then just use another one.
So the Immortal Master Guiyi swung his sword again and again, continuously destroying the autonomous mechanical aggregate.
At the same time, the immortal soldiers and immortals under his command were also rapidly being destroyed under the attacks of the autonomous mechanical aggregates.
In a short period of time, more than half of the people were killed or wounded.
It was only because the Immortal Master Guiyi was still at the front line that the immortal soldiers and the immortals were able to barely maintain their morale and prevent it from collapsing.
Even Guiyi Immortal Venerable himself had been blasted through the defense line by the main gun more than once in the fight with the autonomous mechanical aggregate, suffering serious injuries.
At the same time, the immortal power in his body was depleted by more than half. For a moment, even the massive energy produced by the antimatter reactor could not sustain the loss.
As for the autonomous mechanical aggregate, although it also suffered a lot of losses, compared with that of the Heavenly Court, the losses could be said to be minor.
Moreover, the autonomous mechanical aggregate itself is just a machine. It has no concept of fatigue or morale and can fight indefinitely until the last part is lost.
"Is there really an intelligent machine crisis in the technological universe? This is what caused these tireless and fearless war machines? Why hasn't the news from the Immortal Sect come back yet?" Immortal Master Guiyi also became a little impatient.
At this moment, as the Jiuyou ancestor in the cave revealed Lin Xu's identity, suddenly the cause and effect of the entire prehistoric land began to shake. The spiritual consciousness of Guiyi Immortal Venerable trembled, and he suddenly realized that the cause and effect of heaven and earth seemed to have some subtle changes.
The origins of these mechanical creations, which I had been unable to predict, now suddenly became clear to me.
So without caring that he was still fighting, Guiyi Immortal Venerable immediately began to divine.
Although it was a lot slower to divine during the battle, he eventually predicted the result.
This result made Immortal Guiyi even unable to believe his eyes for a moment.
"Pangu tribe? It's actually the Pangu tribe?"
What should we do? Should we continue the fight?
Immortal Guiyi was in a state of panic for a moment.
He never imagined that the mastermind behind the so-called mechanical creation would be the Pangu clan?
How can we fight this?
But, should I just give up like this? I finally achieved the status of Immortal Venerable, but just because the Pangu clan returned, should I give up everything?
Moreover, even if he gave up, what would happen? The Pangu Clan went to Heaven as soon as they returned, and it was obvious that they wanted to harm Heaven.
If I give up, will the Pangu tribe let me go?
The answer is obviously no.
If you want to fight for that glimmer of hope, you have to face the challenges head-on.
This is what I, Guiyi Immortal Venerable, have been seeking all my life.
As soon as he thought of this, he instantly felt his thoughts become clear.
That’s right, so what about the Pangu clan? This primitive world is no longer the primitive world you lived in ten thousand years ago.
This chaos was indeed created by you.
But today's wilderness is the wilderness for us wilderness people.
This great fortune of the ancient times also belongs to us, the people of the ancient times.
"Pangu tribe? I am targeting the Pangu tribe."
Guiyi Immortal Venerable roared, and in an instant a sword that pierced the sky and the earth was slashed out.
This sword instantly exhausted all the immortal power in his body. The power of the sword was so strong that it directly blew up a temporary warship in front of him, and caused several warships to explode in succession.
However, this sword strike also exhausted his spiritual power.
However, immediately afterwards, a surge of power emerged from the body of Guiyi Immortal Master and instantly filled his whole body. In just the blink of an eye, Guiyi Immortal Master had recovered all his strength.
This is the Nine-Nine Return to One Method that made Guiyi Immortal Venerable famous. It can store enough immortal energy in normal times, compress it at one point, and demonstrate it when the immortal energy is exhausted. It can instantly restore all the immortal energy nine times in total.
It is precisely by relying on this unity that the Immortal Venerable Guiyi can suppress countless powerful beings and occupy the land of heaven.
Of course, when Immortal Guiyi used the Nine Nine Return to One at this time, he was not trying to risk his life.
Even if he had to fight to the death, he would fight with the Pangu clan. What was the point of fighting with a bunch of mechanical creatures?
And although he has decided to move forward bravely, relying on the sword in his hand, he can fight for a chance of survival from the Pangu tribe.
But it doesn't mean to rush in blindly, but to be strategic.
First, he used this sword to force back a large number of temporary warships during the battle, and passed the message to Liuyun and Qingying of Buzhou Mountain that the so-called mastermind behind the scenes was the Pangu clan. Don't investigate anymore, retreat quickly and preserve your manpower.
Immediately afterwards, Immortal Venerable Guiyi led the remaining hundreds of thousands of immortal soldiers and more than ten thousand immortals on the battlefield to retreat.
Just abandon the Heavenly Palace and retreat to the hidden place secretly prepared by Guiyi Immortal Venerable in case of any emergency, and then plan for the future.
However, the immortal soldiers and immortals in heaven had the Immortal Master Guiyi to cover their retreat, so it was relatively easy for them to retreat.
But it’s different here in Buzhou Mountain, because there is no one like Guiyi Immortal Venerable to cover our retreat.
You can't just withdraw in the middle of a fight.
And Guiyi Immortal Venerable was obviously unaware that the fighting here was actually reaching a fever pitch.
"We can't retreat. If we retreat now, we will be followed and hunted down. By then our morale will be low and we won't even have the strength to fight back." Qingying disagreed.
Just like on ancient battlefields, a large number of casualties often did not occur on the battlefield, but during the chase.
"This is the order of the Immortal Lord. Do you want to disobey it?" Liuyun shouted angrily.
Liuyun Jinxian is different from Qingying. Whatever the Immortal Lord says is always the truth.
Although Qingying Jinxian liked to daydream, he was rather timid. As soon as Liuyun Jinxian mentioned the Immortal Lord, he dared not say anything.
And just like that, the order to retreat was immediately issued.
The millions of immortal soldiers and tens of thousands of immortals who were in the midst of a fierce battle were at a loss for a moment. Although they had been slaughtered unilaterally by Nei Mu Xiyue before, they were not without any ability to fight back.
But now with the order to retreat, some people accepted the order and began to retreat, but some people were unwilling to do so and still wanted to fight.
But it was the majority who retreated.
However, under Mu Xiyue's sword strikes, this retreat quickly turned into a defeat.
Millions of immortal soldiers filled the sky, scrambling to flee towards the heaven.
Although Mu Xiyue was a little surprised as to why they suddenly started running, she didn't care.
With one sword, tens of thousands of immortal soldiers fell from the sky and landed on the prehistoric land.
The immortal soldiers fled, and Mu Xiyue chased them, and soon disappeared into the horizon.
The followers of the Yin-Yang Sect who were watching the fight on the sidelines silently made way, as if they were afraid of attracting Mu Xiyue's attention.
"Big Brother, do you think Third Junior Brother was killed by that woman?" Liuyang Jinxian asked in a low voice.
"Shh, don't make any noise, don't let her know we are here to seek revenge." Guanri Jinxian quickly reminded.
Liuyang Jinxian nodded to show that he understood.
At this time, the tens of thousands of Yin-Yang Sect followers seemed to have become deaf and blind for a moment. Everyone guessed that the Wuji Golden Immortal was most likely killed by the fierce woman in the sky who chased after millions of immortal soldiers, but everyone seemed to be ignorant and no one said anything.
After all, helping others to get revenge is not as important as your own life.
In this way, Mu Xiyue chased all the way and went straight to the ninth heaven.
Until he encountered the blocking self-regulating mechanical aggregate, which caused his immortal soldiers and immortals to escape, and then he came alone to rescue him.
Seeing the millions of immortal soldiers and more than ten thousand immortals who were in a mess and had thrown away their weapons and armor all over the sky, the hundreds of feet tall incarnation of Guiyi Immortal Venerable almost popped his eyes out of anger.
"Liuyun, Qingying, what's going on? How come half of the two million immortal soldiers are gone?" Immortal Master Guiyi directly grabbed Liuyun and Qingying and questioned them.
"My Immortal Lord, we have encountered the Pangu clan." Qingying said first.
"Pangu clan? Is that it?" Guiyi Immortal Venerable had already seen Mu Xiyue who was killing people in the back.
Mu Xiyue also saw the incarnation that was hundreds of feet tall, and the real body underneath the incarnation.
His eyes immediately lit up and he rushed straight towards Guiyi Immortal Master.
"Yes, it's her." When Qingying saw Mu Xiyue rushing towards him, he was so scared that he trembled all over. If it weren't for the Immortal Master Guiyi who was still by his side, he would have started running away.
"Okay, let me meet her for a while." Guiyi Immortal Venerable's emotions gradually calmed down.
His original intention was to hide first, secretly look for the traces of the Pangu tribe, and then go forward to challenge them directly.
As long as they can defeat the Pangu tribe, there will be a glimmer of hope.
But I didn't expect to meet the Pangu tribe.
But this is also good. When two brave men meet on a narrow road, the brave one wins. Life or death depends on today.
"Immortal Lord!"
"It's the Immortal Lord."
At this time, countless fleeing immortal soldiers and immortals also discovered the Immortal Master Guiyi.
However, Immortal Guiyi no longer had the heart to pay attention to them. He was staring at Mu Xiyue intently.
As Mu Xiyue got closer, the two of them slashed out with their swords at the same time as if they had made an agreement.
In an instant, the mountains and rivers changed color, and the sun and moon lost their light.
The entire battlefield was filled with sword lights that had been condensed to the limit, flying towards the enemy.
Millions of immortal soldiers fell silent.
Even the temporary warship that was chasing after the Immortal Master Guiyi was temporarily stopped nearby under Mu Xiyue's command.
For a moment, only Mu Xiyue and Guiyi Immortal Venerable were left on the battlefield.
As well as the millions of immortals and autonomous mechanical aggregates watching from afar.
With a loud bang, the colliding sword energy was like a star exploding.
The energy swept in all directions, directly blowing away a large number of already injured immortal soldiers.
However, even so, the remaining immortal soldiers refused to leave, but retreated a distance and continued to watch this top-level battle that was rare even in the entire prehistoric world.
Even without the immortal soldiers knowing, countless pairs of powerful eyes had already silently locked onto this place.
The moment the Nine Nether Ancestor revealed Lin Xu's identity, countless powerful beings in the entire prehistoric world felt the shock of the prehistoric cause and effect. After divination, they basically knew the news of the return of the Pangu clan.
He also learned that the arrogant Guiyi Immortal Venerable in Heaven had actually confronted the Pangu clan without knowing it.
Now, Immortal Master Guiyi is directly fighting against the Pangu clan. It would be strange if these powerful people were not curious about the battle situation.
So countless pairs of eyes have been quietly looking here.
Whether it is the Dragon Lord hidden deep in the sea, the Demon Ancestor hidden in the fairy mountain, or the Yin Yang Tianzun and Yang Yang Tianzun of the Yin Yang Sect, there are many more powerful people who are also watching.
Of course, Yangji Tianzun did not forget to recall his disciples who were heading to Mount Buzhou as soon as possible.
What? The third disciple was killed? This little thing was no longer a concern for Yangji Tianzun.
Revenge? Who wants revenge? I'll send you to see my third disciple first, and then I'll see if you still want revenge.
Boom, boom, boom.
The sword energy continued to explode and collide, and Mu Xiyue's figure kept leaping in the turbulent flow of sword energy.
Immortal Master Guiyi relied on his huge external incarnation to open and close his body, and the overwhelming torrent of sword energy enveloped Mu Xiyue.
But Mu Xiyue was calm and fearless, and was even excited.
She hadn't felt such an intense battle in a long time.
The most intense battle at ordinary times is probably to compete with Nanzhu for the right to use Lord Lin Xu.
But the result was that they were always sanctioned by Lin Xu. After all, their clans were still inferior to humans in all aspects.
Lin Xu can even beat two at a time.
It was not easy to find an opponent who was equally powerful, so Mu Xiyue was very happy.
I'm even a little afraid of hurting the other person.
However, she did not hold back. After all, only by going all out could she enjoy the fun of fighting.
Moreover, she also discovered that although the fighting power burst out from the immortal on the opposite side was enough to fight against her.
However, they only have low-level authority over the nanorobots, so their endurance is ultimately insufficient.
Although according to the information just passed on by Lin Xu, these so-called powerful beings should be able to have authority infinitely close to intermediate level over nanorobots in the prehistoric universe with the help of the blessing of the prehistoric universe.
But that is not intermediate level authority after all, and endurance is a big problem.
Just like now, when the battle reaches a certain point, the strength of the opponent's sword energy begins to decrease.
Mu Xiyue enjoyed the fight, so she was ready to end it.
Just when Mu Xiyue was about to take action.
The Guiyi Immortal Venerable on the opposite side, who had obviously exhausted his immortal power, suddenly had his whole body filled with immortal power.
It suddenly returned to its heyday.
This surprised Mu Xiyue.
"Nine Nine Return to One, you are worthy of being the Immortal Master Guiyi. Now your Nine Nine Return to One skill has become more and more perfect." A voice sighed in the void.
That is the powerful one who is watching from the dark.
"In this case, won't the Pangu clan lose to the Immortal Lord?"
Other powerful people also spoke up, and several of them actually started conversing with each other.
"Although the Pangu tribe is strong, it seems that they are just so-so."
"If that's all, then the Pangu Clan isn't a cause for concern."
If you think like this, this is not the powerful one who is invisible and watching all around.
Even the Immortal Master Guiyi is now showing great confidence.
"Is this the limit of Pangu's skills? That's all."
As soon as he finished speaking, all the immortal power in Guiyi Immortal Venerable's body gathered, and he swung a sword towards Mu Xiyue in an instant.
This sword was the limit of Guiyi Immortal Venerable's swordsmanship, and this sword exhausted all of Guiyi Immortal Venerable's immortal power.
After the previous tests, he believed that this sword was enough to kill the Pangu clan.
He will step on the corpses of the Pangu clan, enlighten his mind and see his true nature, cut through the illusion, take one step further, and reach a higher level.
At this moment, Guiyi Immortal Master is invincible.
"Guiyi Immortal Venerable, so terrifying."
"His strength has improved again."
"To defeat powerful enemies repeatedly, the stronger they are, the stronger they become. This is unity. I am not as good as him."
"After this battle, I'm afraid the power of Heaven will rise to a higher level."
"Perhaps, he is the only one who can challenge the Hongyuan Patriarch."
Many powerful people sighed.
In the battle just now, while observing the Immortal Master Guiyi, they were also observing Mu Xiyue.
As powerful beings, they naturally realized that Mu Xiyue had actually reached her limit.
That's the extent of her strength.
Now that Immortal Guiyi had swung such a terrifying sword, it was impossible for her to dodge it.
However, just when everyone thought it was impossible.
Mu Xiyue's whole body suddenly became vague, as if it had left this universe and this dimension.
At the same time, a long sword that looked extremely ancient appeared in her palm.
But the long sword inexplicably gave everyone the feeling of being alive.
It was as if the ancient sword was actually an extension of the body organs of the person in front of it.
This is indeed the case. This long sword is the high-dimensional organ that Lin Xu transformed for Mu Xiyue.
Different from Nanzhu who chose to transform his tail, Mu Xiyue chose to transform an external organ, which is this ancient long sword.
And now, Mu Xiyue finally used this sword in battle for the first time.
Mu Xiyue used her external organs to open up a high-dimensional perspective, and with that high-dimensional perspective, she could see through all the details of Guiyi Immortal Venerable's sword at a glance.
Then, she swung the ancient long sword in her hand, and released a sword energy that was almost invisible compared to the sword energy of Guiyi Immortal Venerable.
Afterwards, the sword energy formed by high-dimensional power met the sword energy that suppressed the heaven and earth.
The sword energy formed by the high-dimensional force instantly changed the physical rules of the surrounding area and eliminated the basis for the existence of the sword energy that suppressed the heaven and earth.
In an instant, the sword energy that was infused with all of Guiyi Immortal Venerable’s power and that overwhelmed the heaven and earth disappeared in an instant.
It's as if it never existed.
Because the basis for the existence of that sword energy was eliminated in an instant, and the sword energy also disappeared.
Although the foundation was restored after a moment, the sword energy could not be restored.
"This, this is impossible, how did you do this?"
"She, how did she make the sword energy of Guiyi Immortal Venerable disappear? This is simply a magic trick."
"Incredible, incredible, is this the Pangu tribe? Has she only started to take it seriously now?"
"Is it only when Guiyi strikes with all his strength that he is qualified to make her take him seriously?"
All of a sudden, countless powerful beings began to become complicated.
After slashing out with the sword, Guiyi Immortal Venerable, who had instantly recovered all his strength, was also stunned.
He has already used up three times of Nine Nines Return to One today, and has six chances left.
Theoretically, it is possible to unleash six more devastating sword energies.
But what else can he do if every time it is easily resolved?
Moreover, Mu Xiyue obviously didn't intend to give him the chance to strike with that sword.
She was already planning on ending the fight.
"You are worthy of being the Lord of Heaven since you can let me use Penglai. But you no longer have a chance." Mu Xiyue held a sword in her hand, and said casually as she slashed at the location of Guiyi Immortal Venerable.
She named her external high-dimensional organ Penglai, the same as the fairy ship Penglai, in order to commemorate the fairy ship Penglai.
"Also, there is one more thing I want to clarify. I am not from the Pangu clan. I am just a member of Pangu's family." As Mu Xiyue finished speaking, a sword energy that seemed harmless but made the Immortal Guiyi's hair stand on end came towards her.
However, what made Guiyi Immortal Venerable shiver all over was what Mu Xiyue said.
"Pangu clan? You are only a member of Pangu clan?"
Guiyi Immortal Venerable knew about Pangu's clan, but in his eyes, there was only Pangu's clan, and he never took Pangu's clan seriously.
But he didn't expect that he couldn't even defeat a member of Pangu's clan.
What an irony!
The other powerful people who were watching also had similar feelings to Immortal Master Guiyi.
It's all mixed emotions at the moment.
It seems that we have been sighing for so long, but it turns out that they are just Pangu's family.
So what does the real Pangu clan look like?
Are the Pangu tribe really that terrifying?
They created the primitive world and now they have returned. What is their purpose?
Will this be a catastrophe that will last forever?
Nobody knows.
Especially the Immortal Master Guiyi who faced Mu Xiyue's sword head-on, there was only deep self-mockery in his eyes.
