As long as you hold the Cuishan Pass, Langya, the rich land of fish and rice behind you, will be safe and sound, this is also the reason why Yan rejected the Donghu people back then, Liaoxi County has been occupied by the Donghu people many times in history, but because of the Kunshan Pass, the Donghu people have never entered Langya, and bypassing the Kunshan Mountain, for the Donghu people, the gains outweigh the losses, hundreds of miles of mountainous areas are inhuman, so that the Donghu people who were fighting at that time could not raise any interest at all.

Whenever the Yan State became stronger, the army would try to recover Liaoxi County from the Kunshan Pass, and even drive the Donghu people back to their hometown completely, the war lasted for many years, until the emergence of Zhang Shouyue, this young general from a poor background, from leading dozens of people to be the king of the mountain to oppose the rule of the Donghu people, with the Yan army that came out of the Kunshan Pass at that time, after war after war, Zhang Shouyue began to rise, and finally expelled the Donghu people from Liaoxi, and returned Liaoxi County to Yan, And Zhang Shouyue also became the first civilian county guard in the history of Yan Kingdom, and he was there for decades.

Because Liaoxi County was reclaimed, the pass lost its former function, and in the following decades, it was gradually abandoned, and at its most desolate, only a few dozen soldiers and a tax collector were stationed, and the only function was to collect taxes and fees from the merchants who passed from here.

It wasn't until Gao Yuan rose strongly and drifted away from the Yan Dynasty that Hu Yanchao was stationed in Langya County that Kunshan Pass once again received unprecedented attention, but this time, it was not to defend against the Donghu people, but to guard against Gao Yuan.

After several years of repair, the dilapidated Kunshan Pass has been rejuvenated to resist the strength of the Donghu people, the new and old bricks of the city wall more than ten meters high are mottled with each other, the new bricks are just wrapped up in the past two years, the fluttering flags, the swords and guns stand in a forest, and the soldiers who are refreshed. It gives new life to this dilapidated old city.

This is an obstacle that the Eastern Army must break into Langya County, and Hu Yan is naturally very aware of this, so here, he put Wu Bo, a fierce general under his command, and the soldiers under his command are all old soldiers he brought out from Liaoning Wei at the beginning, guarding the Kunshan Pass, so he has the ability to refuse the Eastern Army outside Langya County.

Zhang Xi's whole body was covered with branches and thatch, and he crouched quietly behind a bush, staring at the towering Kunshan Pass in the distance. He knew that it wouldn't be long before this place would become a battlefield of flesh and blood, as a scout, he had been in and out of this area often in the past two years, so to speak, it was to watch the Kunshan Pass change from a dilapidated place to what it is now, and if he wanted to build such a city, he was afraid that the loss would not be small. On both sides of the pass are steep mountains, and if you want to attack the pass, you have to enter through a narrow valley. And now, Wu Bo, the guard of Kunshan Pass, has built some walls in the canyon. Just opening up this canyon is not a simple matter.

Seeing this, he couldn't help but have some itchy teeth.

The sound of golden drums in the distance. Woke up Zhang Xi, he took a deep breath, he was just a scout, leading the troops to fight, that should be something that the generals leading the troops should think about, he can't manage it, and he doesn't have the ability to manage it, as long as he does his own thing, it's enough.

His gaze moved back to the direction he had come.

In this revenge chase, the scouts of the two sides broke out into an unprecedented fierce battle, and in the end, the Eastern Army won the final victory, and the scouts of the Yan Army completely withdrew from this area, but Zhang Xi did not find the figure of the Yan Lingwei spy.

Zhang Xi was convinced that this person had definitely not yet stepped out of this area, because the scouts of the Eastern Expeditionary Army were definitely far more familiar with this area than this person, and the shortest and most direct path they had taken was the shortest and most direct path, and that person could not be faster than them.

While the rest of his comrades were still searching in the rear, Zhang Xi was heading straight for the Kunshan Pass, where he was only a few miles away from the Yan army's first wall in the canyon, and if the spy could avoid his companions, he would have appeared here and not somewhere else.

Aside from the hostility between the two sides, Zhang Xi still admires this guy, who has been able to support himself until now under so many scouts searching and pursuing. If you can catch him, you should really ask him what his name is, but if you really let him come here, I am afraid that I will not have the opportunity and time to interrogate him.

Between the woods nowhere, the frightened birds flew, Zhang Xi suddenly perked up, stared at the place with wide eyes, and after a while, the sound of hurried footsteps came, and a gray figure rushed out of the forest, rushing towards the wall here, on his back, there was also a feather arrow, looking at the person, Zhang Xi let out a long breath, and finally saw this person. He tightened his grip on the hilt of the knife, and at this time, behind the man, several scouts of the Eastern Army also appeared, and they did not care at all about the defenders of the Kunshan Pass not far away, carrying knives, desperately chasing the figure in front of them.

After more than ten days, they finally caught the man's trail and injured him, and now even if there is the Yama Hall in front of them, they will move forward bravely.

Xu Yanmao was exhausted, for more than ten days, he felt like he had stabbed a hornet's nest, and the scouts of the Eastern Army were chasing his tracks like a madman, if it was an ordinary soldier, he could naturally easily get rid of his opponent, but the problem was that the other party was the scout who was the best at tracking and reconnaissance.

He didn't have time to sleep well, he didn't have time to eat a full meal, most of the day was spent on escaping, today, he finally saw the wall of Kunshan Pass, but just when his mind was a little relieved, those ghosts of the Eastern Army scouts immediately pounced.

A fight injured several of them, but he also suffered an arrow, and finally broke out of the opponent's encirclement, and saw the wall in the valley in front of him and the soldiers on the wall, Dayan's soldiers.

"Help, help!" He opened his hands and waved desperately at the soldiers on the wall in front of him, howling loudly, as long as the soldiers in the wall rushed out, the scouts of the Eastern Army chasing behind him had no choice but to escape, and his life could be regarded as picking up.

In the canyon, there are a total of three walls, Wu He is the commander of these three walls, in this canyon, there are a total of 1,000 soldiers, they are the first line of defense of the mountain pass. Today, Wu He happened to be patrolling the first wall.

Hearing the shouts for help from the distance opposite, I saw a person wearing the uniform of the Eastern Expeditionary Army running towards here, and behind him, several other soldiers of the Eastern Expeditionary Army were carrying knives and were chasing and killing them murderously.

"Fraud the city gates?" Wu He thinks it's a little ridiculous, this person is too few, right? Moreover, these are just three simple city walls in the canyon, and General Wu doesn't expect to be able to stop the opponent for long, even if he loses it to the opponent, it is not a big deal, and the opponent is still very bored with what tricks he plays.

"Help, I'm Yan Lingwei Xu Yanmao." The man shouted as he ran, and this time his shout, Wu He heard it clearly. The name Xu Yanmao is unfamiliar to the vast majority of Yan Jun, but Wu He just knows such a person, Xu Yanmao, a former senior official of Yan Lingwei, was eaten and hung up because of the escort of Ye Xiang, was assigned to Langya, and later threw him to Liaoxi County.

He hasn't been heard from for two years, and all the senior officers in Langya think that such a person has already died in the prison of the Liaoxi County Supervision Yuan.

But now, he has actually returned, such a person, if he returns, he will definitely bring extremely important information." Quick, get out of here, get him back."

Wu He choked and pulled out his knife, so he drew his knife and rushed under the wall.

The door was closed and opened, Wu He rushed out first, just rushed out a few steps, Wu He suddenly paused, in his sight, the surprised expression on Xu Yanmao's face was clear at a glance, but when he rushed through a bush, a large ball of thatch behind the bush suddenly flew up, and a cyan human smoke jumped out and appeared behind Xu Yanmao, the cold light flashed in his hand, and a short dagger was deeply pierced into Xu Yanmao's flank.

Xu Yanmao's smile froze on his face.

Zhang Xi drew his sword and quickly retreated, as a veteran scout, he knew that this knife had cut off all the opponent's chances. He quickly threw away all the disguise on his body, turned and ran.

"Run!" He shouted loudly at the few scouts of the Eastern Army who were stunned, because at this time, Wu He finally reacted, and in the roar, he led dozens of soldiers to rush towards them.

"Quick, into the woods!" A few scouts turned and ran.

Wu He stopped beside Xu Yanmao, he slowly squatted down and helped Xu Yanmao up, "General Xu." He screamed softly.

The knife stabbed from under the flank, and Wu He only glanced at it, and knew that it was hopeless. Xu Yanmao stared at him, trying his best to say something, but as soon as his lips moved, a large amount of blood gushed out of his mouth, and he looked at Wu He, and his eyes welled up with deep sadness.

He knew a lot of secrets about the Eastern Army, knew the number of troops marching into the Eastern Army, the route, in addition to the Kunshan Pass, there was another army that made a detour through hundreds of miles of mountainous areas, entered an uninhabited area, and turned to attack Xinxiang, but now he can't say a word.

The hand was raised high and hung down suddenly, Xu Yanmao was unwilling, his head was crooked, and he died like this. (To be continued......)
