There was an eerie silence in the empty city, which made people feel creepy. Mr. Ya waved his hand and his men immediately scattered to search the houses in the city.

The residential courtyards are built along the river, winding around it. It is easy for outsiders to get lost wandering around in it. Sometimes they will encounter some big rocks blocking the way, making the already confusing terrain even more confusing.

Mr. Ya had a bad feeling in his heart and suddenly began to regret his reckless behavior.

At this moment, a Western soldier shouted loudly, and everyone around him immediately became frightened birds. Some drew their swords, some drew their swords. Many soldiers in armor quickly formed a circle, each pointing the black muzzle of their guns at the strange locust tree. A Western soldier was hanging slowly from the locust tree, half of his head had been blown off. No one knew in which battle he died. A pale round-faced mask was tied to his bloody head - this time the mask turned into a crying face!

A loud roar was heard. It turned out that a Western armored soldier was so nervous that he fired his cannon. The corpse on the tree was immediately blown into a pile of pieces of flesh, which fell down with a crackling sound. Then, a burst of creepy laughter was heard, and the Western soldiers under the tree retreated one after another as if they were facing a powerful enemy.

A moment later, a round-faced owl popped its head out from the treetops, looked proudly around at the two-legged creatures under the tree, flapped its wings straight up into the sky, and spread its eerie laughter everywhere.

In broad daylight, it was enough to scare people into breaking out in a cold sweat.

"Master Jacobson, shall we continue the search?"

Mr. Ya swallowed hard and said, "No... Get out of here first, quickly!"

Before he finished speaking, a sharp explosion was heard in the distance, followed by several screams, and several huge fireworks roared into the sky, exploding into a sea of ​​fire.

Suddenly someone changed color and said: "We were ambushed!"

"withdraw!"

"Get out of there!"

The sound of cannons and arrows merged into one. Several explosions caused by unknown sources pushed down the already shaky stone house. The messy stones were connected to the huge rocks that had originally blocked the road, and the empty city became a huge maze.

The map in the hands of the Westerners became completely a piece of waste paper. The disadvantage of outsiders' unfamiliarity with the terrain was clearly revealed. A group of heavy armored soldiers and infantry were trapped in it for a while, bumping around like headless flies for a while, and they couldn't get out!

Mr. Ya had no choice but to blow the whistle to call the Western Eagle Armor, which flew into the air to give orders and finally lure the people out.

The Western army, having just recovered from their shock, retreated to the city gate. Someone triggered a mechanism, and suddenly there was a tooth-grinding sound of gears on the city gate. All of a sudden, all bows and arrows were drawn, and thousands of arrows were ready to be fired at the city tower. Something slowly fell from it...

Mr. Ya pushed aside the frightened guards and took a closer look. He was so angry that his nose almost got crooked. It turned out to be another white mask, but this time it was a ghost face!

Mr. Ya: “…”

"Sir, shall we...should we take a detour?"

Mr. Ya raised his hand to interrupt him, and stood there for a moment with a sinister look on his face: "Your Majesty is right, Gu Yun has no trump card in his hand, and can only rely on these inferior tricks. Are you scared by him using a few broken masks? An ambush... ha!"

He laughed in anger and said coldly: "Tear down this city for me, and I'll see where they can hide!"

However, more than an hour later, Mr. Ya, who had razed the entire empty city to the ground, searched the ruins three times and finally had to admit that this ghost place, which had wasted countless of his precious time and Zi Liujin, was really an empty city. The so-called "ambush" was only two masks and an owl that had flown away long ago!

Mr. Ya's gums were almost bleeding from biting his teeth: "Where's the Pathfinder Eagle? Chase it! Chase it at full speed!"

At this time, on the only way from Dong'an to the capital, Gu Yun, who was hiding under a tree, took the clairvoyance handed over by Tan Hongfei and watched a few scouting eagles whizzing past his head and flying towards the direction of the capital.

He spat out the grass stem in his mouth and patted Lian Wei's wind-cutting blade behind him: "Old Lian, you have done a great deed."

Tan Hongfei asked in a low voice: "What's the matter?"

"Have you figured it out?" Gu Yun said lazily, "The foreign manager must be dead or injured now. The person leading the troops now is obviously not familiar with the capital area, otherwise he would not rashly send out scout eagles in anger."

The imperial city is located in the center of the capital, and the capital area has always been strictly guarded. No one is allowed to peek at will. Even the Black Eagle dares not fly around. Even in extraordinary times, the Black Eagle only dares to stay in the Beidaying garrison, remove its eagle armor, and ride into the capital on horseback.

But most people don't know that the reason why the Black Eagle dared not fly was not because the Black Iron Camp was particularly abiding by the rules, but because Gu Yun knew that once the Black Eagle crossed the border and flew in, it would easily touch the "No-Fly Net".

Outside the nine gates of the capital, there is an invisible "forbidden air network" that was first built during the reign of Emperor Wu and took thirty years to complete. It is the masterpiece of Lingshuyuan. There are countless hidden stakes under the forbidden air network, and the general dispatch is on the Qiyuan Tower. "

The reason why Qiyuan Tower was built so high, in addition to providing a place for guests from all over the world to eat, drink and have fun, is that it has a very important function - it is the main stake of the forbidden sky net. There is a "Heavenly Round Square Pavilion" on the "Star Picking Tower", which is usually locked tightly. Lingshu Academy has worked so hard to build this Heavenly Round Square Pavilion that it will create a special light net outside the nine gates. It is very fine and dense, and even at night, it will be easily covered by the stars, the moon or the fire. Unless you are gifted, it is almost invisible to the naked eye.

This layer of light net is thirty feet above the ground and will not affect the movement of people and animals on the ground. If someone flies over on an eagle armor, they will definitely be discovered by the Nine Gates Guards at a low altitude of thirty feet, and there will be white rainbow arrows waiting for them. Once the eagle flies more than thirty feet high, it will touch the no-fly net.

The light net that is touched will be refracted back to the Tianyuan Square Pavilion, and then hit back to the hidden stakes underground in the no-fly zone through special mirrors. Those hidden stakes will pop out with the light signals from the sky, lock the position of the invaders, and shoot arrows from eight directions at the same time. If the Eagle Armor dodges, it will find that within the range of the no-fly zone, there will be hidden stakes following it wherever it hides.

Only on New Year's Eve, the Tianyuanfang Pavilion will undergo an annual maintenance and the no-fly zone will be temporarily closed, with the sentries on the Red-headed Kite taking over the lookout.

"The Pathfinder Eagles will never come back. The foreign commander will soon remember the legendary no-fly net. When the beacon fire order is issued, all the red-headed kites will take to the sky, and the position of the no-fly net will also be adjusted. They will not be able to figure out where the thing has moved to for a while. The closer they get to the capital, the more they dare not put the eagle armor too high..." Gu Yun whispered to Tan Hongfei, "Pass the order down, let the brothers rest well, and start at night. The Black Eagle will go first and suppress the enemy from a high position. The light cavalry will then rush from both wings to break up the enemy formation. Don't fight to the death, just leave after one strike to avoid being trapped. The chariot soldiers pretend to cut off their retreat, bomb them for two or three rounds, and then let them retreat. Don't force the other side to fight to the death. We don't have enough troops."

Tan Hongfei asked quietly: "Marshal, why don't we set up an ambush in the city?"

"Who would ambush someone in broad daylight?" Gu Yun rolled his eyes. "Are you crazy?"

...Mr. Ya must have sneezed twice.

Tan Hongfei thought about it for a while and felt that it made sense, so he asked again: "Marshal, how do you know they will come here at night?"

Gu Yun: "Your King Yanbei calculated it. If he made a mistake, fine him. Anyway, his New Year's money is equivalent to half a year's salary for me."

Chang Geng was sitting at the side repairing the leather grip of an iron bow. After a night of fighting, the grip was a little worn out. He took out a knife, a file and a small piece of leather from somewhere. His ten fingers were so nimble that it was dazzling. When his name was suddenly called, Chang Geng smiled at Tan Hongfei without even looking up, "Anyway, everything is on the account of the Marquis' Mansion."

Tan Hongfei was a rough man, "those who are my comrades are all brothers", and after fighting side by side, he had already regarded the King of Yanbei as his own, and did not care who his mother was. After hearing this, he immediately joked without restraint: "Our prince and the commander are no different, it would be great if he was a princess, maybe we can have more princess tents in our Xuantie Camp like we did in the past."

Gu Yun: “…”

He couldn't help licking the itchy roots of his teeth.

Chang Geng paused, and followed Commander Tan's words, "It's a pity that I don't have a beautiful face, and the Marshal who threw fruits all over the cart refused to take them."

Tan Hongfei said heartlessly: "Oh, that's not right. The emperor usually calls our commander 'imperial uncle', there is a generation gap!"

Gu Yun: "...Get lost!"

Commander Tan, who was just joking, and King Yanbei, who had ulterior motives, looked at each other and laughed.

At night, a cuckoo bird called not far away, which was a signal that the enemy had entered the camp. As soon as Tan Hongfei moved, he was held down by Gu Yun.

"Wait a little longer." Gu Yun whispered, "Wait until the fourth watch."

His eyes shone frighteningly bright in the dark, like a pair of divine weapons sharpened with the sight of blood.

Tan Hongfei couldn't help licking his cracked lips: "What did the prince plan? It's really..."

Gu Yun was about to say "His teacher was General Zhong", but Chang Geng, who had come over from nowhere, suddenly said from behind: "He trained himself by calculating carefully all day long."

Tan Hongfei: "What?"

Chang Geng glanced at Gu Yun and said, "I need to save up my dowry so that I can marry the general."

Gu Yun: "You two are not done yet, right?"

Tan Hongfei laughed like an idiot. Gu Yun was helpless with this bastard who was responsible for "bringing up irrelevant issues" and "sparing no effort to add bricks to the commander's heart" - he didn't know when it started, but Chang Geng became more and more unscrupulous in front of him. Gu Yun advised him to "carry less baggage" in the hot spring villa at that time, and he actually listened to him and let him "go into battle lightly".

Chang Geng knew the way forward and backward very well. After making fun of Gu Yun, he immediately made amends and said, "Godfather, I was just joking. Don't be angry."

Tan Hongfei: "Our Marshal is not that magnanimous. In all my years as Old Tan, I have only seen him lose his temper once in the palace..."

After these words were spoken, even Tan Hongfei realized that he had said the wrong thing and fell silent in embarrassment.

The expression on Gu Yun's face immediately faded.

Tan Hongfei couldn't hold back his words, and after a while, he couldn't help but say: "Marshal, that matter..."

Gu Yun interrupted him: "Tell Xuan Ying to prepare!"

Tan Hongfei clenched his teeth, finally helpless and sighed.

Chang Geng patted his shoulder and said, "I'll go."

The night deepens, the moonlight fades, and the light is just beginning to rise. It is the darkest time before dawn.

Mr. Ya was terrified during the march during the day, and was repeatedly worried about being ambushed by Gu Yun. He was filled with fear and anger, and he did not dare to relax even when he set up camp at night, fearing that Gu Yun would suddenly attack him after making false plans along the way. He did not dare to sleep a wink all night.

As the long night was almost over and there was still no movement around, Mr. Ya finally couldn't hold on any longer and took a short nap.

Unexpectedly, just as he was about to fall asleep, he heard a loud noise like a camp explosion outside. Mr. Ya broke out in a cold sweat and rushed out. The entire night sky was on fire.

"My Lord, get out of the way!"

A cluster of flaming arrows fell from the sky, and Mr. Ya was pushed away by a guard. The night wind was steaming as if it had been roasted. Then shouts of killing arose, and two teams of black cavalry rolled over like a black whirlwind.

"Hold on with your heavy armor!" Mr. Ya shouted, "Don't panic, the Central Plains people don't have many soldiers..."

Before he could finish his words, there was a loud noise behind him, and a row of chariots rushed out from nowhere, causing chaos and flying sand and rocks.

Mr. Ya is an expert at sowing discord, forming alliances and scheming, but he is not a very effective commander on the battlefield. He is too used to thinking carefully, and once the enemy exceeds his expectations, it is easy for him to fail to react in time and lose control of his subordinate troops.

Suddenly, an indescribable chill crept up his spine, and Mr. Ya felt as if he was a frog caught by a snake's murderous intent. He looked back in fear, only to see an iron arrow streaking across the night sky like a meteor chasing the moon, heading straight for his face.

Mr. Ya had no time to dodge. At the critical moment, one of his Western heavily armored soldiers roared and blocked in front of him. The iron arrow actually penetrated the thick steel plate of the heavy armor, and a sinister tip appeared from behind the armored soldier.

Mr. Ya, having just recovered from his shock, looked in the direction of the attack and saw a young man standing on the back of a black eagle holding a longbow.

He had a telescope on his nose and looked down at him... no, he glanced at him with a poisonous look.

Mr. Ya's personal soldiers immediately aimed their cannons at the Black Eagle in the air. The young man seemed to smile, and shook his head with an indifferent expression as if "this target was unfortunately not hit", and then leisurely jumped down from a low altitude of five or six feet, separating from the Black Eagle one above and one below, just avoiding the cannon filled with smoke.

Gu Yun rode forward and caught Chang Geng who jumped down from the eagle's back. The wind-cutting blade in his hand was swirled into a whirlwind with invisible blades under the impetus of steam. The horse's hooves were raised high, and the wind-cutting blade swept across a circle. There was a continuous shriek of "Woo". Someone's blood splashed on the cinnabar mole at the corner of his eye. He stepped on the horse's belly, and the warhorse jumped out of the battle circle in a blink of an eye.

Gu Yun slapped Chang Geng hard on his body: "Asshole, don't you want to die?"

Chang Geng wanted to jump directly down, and when he was about to land, he used the light fur leggings on his feet to push against the ground to speed up and cushion his fall. Unexpectedly, Gu Yun intervened. He stared at Gu Yun's face so close to him in a daze. His chest shook violently and he almost fell down. He had to grab the cold iron armor on Gu Yun's wrist.

His eyes instantly tore through the calmness on the surface, and were as blazing as substance. Gu Yun asked unhappily, "What are you looking at?"

Chang Geng managed to calm himself down, retracted his flaming gaze, and said with a dry cough, "...It's time to cast the net."

Gu Yun pulled him to his chest, turned his horse and blew a long whistle. All the light cavalry gathered immediately and rushed towards the enemy camp like a blanket. The Western army, which had been bombarded by the black eagle in the sky, did not start to organize until then. Mr. Ya roared: "Heavy armor leads the way, tear a hole in the back!"

There was no need to tear open a gap in the rear. The tank line of the Beidaying was deliberately left very thin. At the slightest contact, they would retreat as if defeated, allowing the Western troops to retreat.

Gu Yun gestured to Tan Hongfei who was not far away, and the Black Iron Cavalry retreated quietly, like a group of unruly wild wolves, taking a bite and running away, stopping when they saw the opportunity.

Otherwise, by the time the Western army had regained their balance and reacted, their small number of cavalry would have been nothing more than a mess - of course, by the time they reacted, the black whirlwind had already passed, disappearing into the night and could never be found again.

On April 15th of the seventh year of Long'an, the Xuantie Camp attacked the Western Army at night to the west of Dong'an City.

On April 17, the Western advance army had been led by the Black Iron Camp for two days and could not bear the harassment. It requested reinforcements from the sea and remained motionless.

On April 23, the Western Army reinforcements arrived and the Black Iron Light Cavalry was forced to retreat. The Western Army took advantage of the victory to pursue them and rushed to Wuqing, but they were lured into a trap by Gu Yun, triggering the no-fly net. More than half of the Western Eagle Armor were lost and they had to retreat again.

On April 26, the Pope's condition improved slightly and he immediately led the army in person.

On April 29, Wuqing fell.

On the third day of May, Daxing Prefecture was bombarded by heavy artillery from the Western Army.

Under the relentless pressure of tens of thousands of Western troops, Gu Yun fought with a small group of light cavalry and eagle armor from the Beidaying for nearly a month, but finally could not continue.

On the seventh day, Gu Yun retreated to the capital, the nine gates were closed, and the reinforcements had not yet arrived.

At this point, all grudges and hatreds retreated behind the city walls. The capital of Daliang entered summer under the shade of green trees, but there were no more pleasure boats and singing on the artificial lake in the city. The Westerners finally sent out their hypocritical envoys.
