Gu Yun was not born with a humble and open-minded character. Even though his frivolousness in his youth had been tempered by the yellow sand of the Western Regions, his inner nature was still that of a stubborn person.

He is unruly and has a pure heart. Over the years, no matter whether others praised him or scolded him, he never took it to heart.

However, in the early morning, Gu Yun, who used the alias Shen Shiliu, was staying in the kitchen to drink. When he suddenly heard Shen Yi say that Chang Geng copied his calligraphy, the feeling in his heart at that moment was indescribable.

For the first time in his life, Gu Yun felt panic. He wished he could have a few more useless ears so that he could listen to every word Chang Geng said about whether his writing was good or bad. He was also secretly worried that his skills were not good enough and he would mislead the students.

This is probably how every father feels when he overhears his child say, "I want to be like my dad in the future" for the first time.

Shen Yi asked him, what if Chang Geng hated him?

He retorted with a big boast at the time - which was actually just complete bragging.

Marshal Gu appeared calmly among the huge army, looking at his godson with a calm face, expecting to see a little surprise - even if the surprise is greater than the joy. Unexpectedly, Chang Geng only gave him a blank face that showed nothing more sad than despair.

He kept a calm face, but his heart suddenly skipped a beat.

Gu Yun thought: "It's over, I'm really angry this time."

There is a kind of person who is born with kindness and affection. Even after experiencing a lot of malice, he can still maintain his shaky kindness with difficulty. Such people are rare, but Chang Geng does have this potential.

He encountered a great change in the blink of an eye, and before he had time to figure out his own shadowy life experience, he was caught up in the chaos of the Northern Barbarian invasion. However, although he was full of confusion about the future, full of powerless anger at his situation, and full of doubts about the Shen brothers whose origins were unknown - he still wanted to save Ge Pangxiao, and still could not help but worry about "Shen Shiliu" who had never been seen.

Along the way, Chang Geng thought about it countless times: Now the whole city is full of murderous barbarians, and Mr. Shen is here, what should he do with his little godfather who takes a long time to step over the threshold?

Who protected him? Who escorted him out of the city?

All his worries turned to ashes when he heard the word "Gu Yun".

Chang Geng suddenly didn't know what expression to use to face Sixteen - Gu Yun.

How ridiculous this is. How could the world-famous Marshal Gu be a sick ghost who couldn't hear or see clearly? Was it necessary for him to worry about him?

Besides, why did Gu Yun appear in such a remote place? Why could the Black Iron Camp, which was supposed to be far away in the Western Regions, gather so quickly?

Did the barbarian prince attack by surprise, or did he step into a trap dug for him by others?

These thoughts suddenly popped up in Chang Geng's mind like fireworks, and then quietly slipped away like meteors. He was too lazy to delve into any of them, but his heart ached - because he had been worrying about her for so long, it turned out that he was just being sentimental and overestimating his own abilities. Chang Geng had already known what "fear" and "heartbreak" were too early, and had also felt despair and near death, but he didn't know that the word "embarrassment" could actually make people feel so heartbroken.

Seeing that he didn't respond with red eyes, Gu Yun finally pulled out a little guilt from his rotten conscience. He sighed, and in front of many enemy soldiers, he knelt on one knee as if no one was around, and carefully took the steel leg off Chang Geng's injured leg. He pressed it gently with his hand covered with a layer of light armor, and said, "The ankle is detached, it's okay, does it hurt?"

Chang Geng said nothing.

Although this child usually acted coquettishly and got angry with him, he would always think of him. At this moment, he suddenly stared at him with such strange eyes, and Gu Yun suddenly felt a little regretful.

But I only regretted it for a moment.

The hard-hearted Anding Hou soon came to his senses: "It has come to this point now, there is no point in regretting it."

So he lowered his head without showing any emotion, picked up Chang Geng's injured leg with an indifferent look, and without even saying hello, he pulled and snapped together the dislocated joint.

Chang Geng's whole body trembled violently, but he did not cry out in pain.

Maybe at this moment, even if someone stabbed him, he wouldn't feel any pain.

Gu Yun picked him up and put him on the horse's back, but found that he couldn't deal with his godson, so he had to stand up and bully the barbarians instead.

He dismounted, met the enemy, and had his bones fixed without even raising his head, as if the armored and armed enemies around him did not exist. But for a moment, no one dared to act rashly - perhaps the word "Gu" on the commander's flag alone was enough to scare the prairie wolves.

The barbarian prince looked at him like a wolf king looking at a hunter who had killed his own people, with deep hatred and excessive vigilance.

Fourteen years ago, Gu Yun’s biological father was the commander-in-chief who killed all the eighteen tribes, the Wolf King - the father of this prince. He still walks on two bony and terrifying artificial legs, all thanks to the old Marquis Gu.

The prince was smart. Even a child like Chang Geng could vaguely figure out something in his confusion, so of course he couldn't fail to react. As soon as he saw Gu Yun, he knew that the situation was hopeless.

As if to fulfill his wish, a sharp sound was heard not far away, and a pale signal tower rushed into the sky like a monkey, exploding in broad daylight.

Then, the black shadows of seven or eight black eagles fell on the giant kite like dark lightning.

The Black Eagle is the biggest nemesis of the Giant Kite. Those barbarians got a batch of steel armor from somewhere, but they are just beginners and look intimidating, so how can they be a match for the highly skilled Black Iron Camp?

Gu Yun calmly withdrew his gaze and said in his particularly aggressive tone: "How is the defeated general of Wolf King Getu? Is he still strong?"

Even when Shen Yi was questioning him face to face and fighting him, he was still polite and well-mannered, showing the demeanor of a great country. The barbarian prince was unable to adapt to Marshal Gu's way of speaking, and he almost choked on a mouthful of blood: "You..."

Gu Yun: "I heard that the Eighteenth Department has an ambitious prince, and he has come up with a plan to 'lose gold'. I'm telling you, prince, you guys want to swallow Daliang in one gulp? Are you really not afraid of being eaten to death?"

This time the Barbarian Prince's expression really changed.

The "Erosion Gold Project" is a top secret of the Tianlang tribe, and was planned by the "Yinghuo" prince after he took over the real power of Tianlang. The steel armor and steam technology of Daliang have made great progress, and the Tianlang tribe missed the opportunity in this regard. In the past ten years, they have been beaten so badly that they have almost no room to breathe. Even the peerless masters who are strong enough to lift a tripod are no match for the heavy armor and iron kite soldiers who have been transformed and matured. Prince Yinghuo is very clear-headed. If he wants to take revenge, it is absolutely a foolish dream to rely on hard battles.

Unless the beam rots from the inside.

Although Daliang is vast and rich in resources, it has no large-scale purple gold mines. Purple gold is the lifeblood of the country and must not be lost. Therefore, the court has issued a clear order to prohibit private reselling. Violators will be punished as "treason". If caught, it is not uncommon to execute the entire family. The power required for various civilian lighter puppets must be purchased from the court's special stores under the imperial merchants with a guarantee letter issued by local parents, famous gentry, and scholars.

However, the black market for purple gold is still rampant despite repeated bans. As the saying goes, "people die for money, birds die for food", there have been countless desperate people willing to make a living for money since ancient times, but having the will to make a living is useless if you can't find a source of goods.

The earliest black market "gold merchants" all went to the grasslands in person to try their luck. Only a few in a million were lucky, and most died along the way.

The Tianlang tribe targeted the black market in Daliang, spending all their money to kill the goose that lays the golden eggs. Every year, they dug out a large amount of purple gold. After paying the annual tribute, they used the extra purple gold to bribe soldiers on the border and defeat them one by one. This is the "erosion of gold".

This matter was slowly being implemented seven or eight years ago. Later, the barbarians got in touch with Huger who had settled in the small town of Yanhui, and the two sides cooperated internally and externally. After these years of preparation, Prince Yinghuo was confident that there was no place in the important border towns in the northern border that he could not reach or see with his eyes.

But this matter is known to heaven and earth, and the main culprit knows it, so how did Gu Yun know it?

Could he really have such omnipotence?

In just a few words, the fight for the giant kite in the sky was settled without any suspense.

The hateful Gu Yun put his hands behind his back and added a stab with a lingering look: "Prince, let me be honest with you. I have been waiting for you in this damn place for a long time. I have nightmares every day and worry that you won't come. If you don't come, how can I clean up these parasites who eat the emperor's food but do nothing at the border? Thank you very much!"

The barbarian prince looked like he wanted to peel off his skin and pull out his tendons. Seeing that he was so angry that he was like a lantern, Gu Yun finally calmed down at Chang Geng's helpless mood and showed a violent smile.

"Erosion Gold Plan, haha, you're talented - no more nonsense, get it for me!"

After saying that, Gu Yun took Chang Geng's horse reins and said, "Your Highness, I am sorry to have frightened you. I will lead the horse for you."

Chang Geng tried his best to glare at him, but even though his gaze was as sharp as a sword, Gu Yun was invulnerable... just like he had never heard Mr. Shen asking him to wash the dishes.

Chang Geng whispered, "Marquis Anding didn't even bring any servants with him. He came to this shallow and thin water incognito. He must have planned it carefully and with great effort."

No matter how angry he was before, he couldn't bear to say a harsh word to Sixteen. At this moment, a sarcastic remark came out of his throat, which choked him to death, and his hands holding the reins were clenched until they turned blue.

"He's so angry that he doesn't recognize me." Gu Yun thought with some melancholy in his heart, "What should I do?"

He has always been good at starting fires, and whoever he sets off will explode, but he is never good at putting out fires. Every time he tries to be soft-hearted and calm things down, for some reason, others will become even angrier.

Gu Yun gritted his teeth and lowered his voice, explaining: "Due to military affairs, I was unable to reveal my identity to His Highness. I am sorry for offending you. I have taken advantage of you in the past. I hope that when you return, you will not complain to the Emperor about me..."

Before he finished speaking, Fatty Ge on the wall suddenly shouted, "Be careful!"

A barbarian who had been hiding in the ruins at some point suddenly pulled the power of his steel legs to the extreme. In the blink of an eye, he was behind Gu Yun and slashed him with a roar.

Chang Geng, who was on horseback, saw it out of the corner of his eye, and forgot all the bitterness in his heart. In a hurry, he instinctively rushed out and stretched out his arms to try to block the long knife for Gu Yun: "Godfather!"

A line of white mist suddenly emerged from under Gu Yun's feet. The light fur coat and heavy armor were not of the same weight. A little power could make a person as light as a swallow. His figure flashed and he jumped onto the horse's back. Chang Geng only felt his waist tighten, and his back hit the thin armor on Gu Yun's chest hard, and then a black shadow flashed in front of his eyes.

Gu Yun's wind-cutting blade was still in his hand, and it was still a smooth black iron rod. The tip had already sunk into the heavy armor's shoulder well with incredible precision. The power on the heavy armor's shoulder was suddenly cut off, and the barbarian's iron arm made a teeth-grinding sound, locked, and stuck the swung long knife in mid-air. At this time, the blade was less than three inches away from Gu Yun's forehead.

And he didn't even blink.

Gu Yun squeezed the horse's belly hard, and the warhorse neighed and rushed out. His hand that was around Chang Geng's waist moved up slowly and covered the boy's eyes. The wind-cutting blade was lifted up by the rushing warhorse, and steam gushed out violently, making a slight explosion sound. A three-foot-long rotating blade was unsheathed and cut off the barbarian from the shoulders up.

A stream of moist, warm steam sprayed onto Chang Geng's neck. He shuddered violently, and then he smelled the smell of blood.

The bitter smell on Gu Yun's body, as if it was marinated in medicinal soup, was hidden under the light fur coat and iron armor, and could not be found anywhere. For a moment, Chang Geng felt that the person sitting behind him was a stranger.

It was as if his little godfather had never existed.
