Since Li Xian had already planned for the enemy's sneak attack, how could he not design some means in advance? In fact, as a tomb robber, Li Xian is also proficient in the production of organs, because he will inevitably encounter some hidden weapons in the process of robbing tombs, and these things have been cracked a lot, and he can't help but learn some, such as today, Li Xian made some mechanisms in advance.

In fact, Li Xian's so-called mechanism is just an extra cover on the trap pit, this cover is made of heavy wooden boards, extremely hard, even the trampling of war horses can withstand it, but this cover is very mysterious, as long as the soldiers leading the rope on both sides gently pull, the planks will shrink to both sides. As for why such a heavy wooden board is so light, it is natural that Li Xian has made an ingenious design from it.

"Open the trap." As Li Xian gave an order, he saw that the soldiers who had been waiting on the side quickly pulled the rope, and a deep and wide pit was immediately revealed not far ahead.

Because it was at night, the Goguryeo soldiers couldn't see it clearly, they were still dreaming of catching Li Xian's promotion to make a fortune, so they urged the war horses to rush to the outside of the camp, but unexpectedly, at this moment, only a miserable sound of horse neighing was heard, and then a burst of people's screams were heard, and the sound of the horse neighing did not seem to happen on the flat ground, but in the underground general, although there are many people now, but it is indeed so clear in the ears of the nearby soldiers, which makes people feel creepy.

At this time, the soldiers who followed closely did not have time to hold the war horse, so they felt that their bodies suddenly sank, and before they could react, they were pierced through the body by the sharp bamboo and wooden guns inside, and they shouted out involuntarily with a miserable scream.

The soldiers behind knew that there had been an accident in front, so they hurriedly reined in the war horses and prepared to watch, but they were unexpectedly squeezed into the horse trap by the group of war horses behind, and then they also involuntarily let out a miserable scream.

So these soldiers fell into the pit like dumplings, and the screams were endless.

By the time all the soldiers had reacted and reined in their horses, hundreds of people had already died in the ravine.

"Fortunately, I didn't rush to the front row, and I was lucky enough to pick up a life." Those surviving soldiers were already afraid, and their ambition to capture and kill Li Xian had also diminished a lot.

But their doom was not over yet, just when they were a little relieved, they only heard a sharp sound of breaking the air, it turned out that Li Xian ordered the launch of crossbow arrows.

I saw that in the dark night, ten thousand crossbows were fired in unison, even if the Goguryeo soldiers wanted to hide, where could they dodge? For a moment, only screams could be heard, and more than 1,000 soldiers in the front row were suddenly shot into hedgehogs.

Although the Goguryeo soldiers were afraid, because the place where they were located was not covered at all, and they were close to the place where the Tang army's crossbow arrows were fired, they could only helplessly become the target of the Tang army.

In this case, those Goguryeo soldiers had only one way to dodge, and that was to desperately retreat to the middle of the camp.

Therefore, the sergeants in the front row immediately turned their horses and turned around, desperately squeezing into the middle of the camp, and some of the soldiers couldn't rush because there were soldiers in front of them, so they had to aim their butcher knives at their former robes, and then step on their corpses to retreat, so as to be able to survive, as for when they will die, they can't care so much, anyway, they can live a little longer.

These situations of attacking their robes were only an isolated phenomenon at the beginning, but later, as the Tang army fired a wave of crossbow arrows again, seeing that the soldiers behind him were shot into hedgehogs, and the death was extremely terrifying, this phenomenon of raising butcher knives for robes became very common in an instant.

And the soldiers in the back row will naturally be wary of the soldiers in the front row at this time, and the worst thing is that those soldiers in the middle have to guard against the front row, but also worry that they will be cut off their heads by the back row of robes at some point, and they are all full of distrust for a while.

At this time, the formation of the Goguryeo army finally became chaotic, killing each other, trampling on men and horses, and the dead were unknown, and the entire military camp turned into a Shura hell, which was extremely bloody and terrifying.

And at this moment, I suddenly heard a sergeant shouting in ecstasy: "Soldiers, don't panic, there is no Tang Army at the west gate of the camp, and the road is open, so you should go here quickly." ”

It didn't matter if this shout, all the Goguryeo soldiers rushed in the direction of the west gate of the camp, and for a while they were crowded with each other, and the people who fought each other for the road were even more so than the others, and the whole thing was already chaotic, and there was no more rules to speak of.

In fact, if you think about it, if you don't see a way out, you will die sooner or later than you can, and the competition is not so fierce, but if you see a glimmer of life, and as long as you fight hard, you can have hope, and it would be strange if they didn't fight desperately.

"Don't be flustered, but go in turn, it's much faster than fighting for the road." Seeing this, Ke Ming hurriedly pressed his sword and shouted loudly, but how effective can his shouting be at this time? The soldiers rushed to run for their lives, and how many of them took his words seriously? Not only that, but even he and the guards around him were almost dispersed by the panicked flow of people.

Keming also tried to stabilize the order, but was surrounded by the guards around him and fled to the west gate of the camp, and even in order to seize the road, the captain of the guard did not hesitate to order the killing of some sergeants.

However, Keming's tragedy was far from over, at this moment, suddenly heard an earth-shattering shouting from behind the battle, it turned out that Li Xian saw that the enemy began to flee, so he ordered the soldiers to pull the wooden planks on the trap again, and then sent a signal, all the armies went out together, from behind the formation, to carry out further blows to the fleeing enemy troops.

In the unfortunate words of Xincheng at the beginning, although Li Xian's army has different colors, they are all the elites of the Tang Dynasty and the end of the Yan Yasu, and the combat effectiveness is no less than those elites in Xue Rengui's army, and there are also fierce generals under Li Xian, and the masters are like clouds, in addition to Li Xian, there are Gao Kan, Xue Ne, Li Duozuo, Zhang Wuchen, Dou Xiantong and others, all of which are rare brave generals in the world. A one-sided massacre was launched against the Goguryeo army, which had long lost its will to fight.

Li Xian led the soldiers under his command to kill the blood flowing like a river, the heavens and the earth changed color, and the officers and men of the Tang Army killed more than 10,000 enemy soldiers and forced to land thousands of people, which was really very happy. Li Xian was happy and ordered someone to report to Hao Chujun and Li Ji, and at the same time reminded Hao Chujun to be careful of the enemy's sneak attack, and ordered someone to clean up the battlefield and repair the walled city, which was very busy.

The enemy's main general, Keming, saw that things were not good, and led the soldiers to flee in panic, and came to the city to calculate the losses, and the 30,000 army lost nearly 20,000, and he couldn't help but be ashamed, and felt shameless to go to see Yuan Nanjian.

When Yuan Nanjian heard that he had lost the battle, his face suddenly turned black as the bottom of the pot, and he immediately ordered Keming to be beheaded, but fortunately, the generals were bitterly forgiven, so he spared his life, but Yuan Nanjian didn't want to let Keming go like this, so he led 20,000 troops the next night and attacked Hao Chujun's camp again.

However, at this time, the military advisor Xincheng once again suggested to Yuan Nanjian that he should take advantage of the victory of Li Xian's army and the relaxation of his heart to immediately carry out a second wave of attacks, instead of attacking Hao Chujun's camp, and it was chosen the next night.

As soon as Yuan Nanjian heard the reason, he ordered Keming to go back immediately to attack Li Xian's camp, but Keming was already afraid of Li Xian like a snake and scorpion, and hurriedly said how brave Li Xian was, and the fierce generals under his command gathered, and the soldiers could fight habitually, and there was no possibility of defeating, and said that he would rather die than go again, and at the same time said that although Hao Chujun was the main general in the army, he was born as a literati, and the combat effectiveness of the soldiers under his command was not strong. On the second day, he attacked Hao Chujun's camp.

But where did he think that after Li Xian's reminder, Hao Chujun had realized that the enemy army would attack, he used various defensive facilities in the battalion, ordered to defend it strictly, Keming fought fiercely all night, did not get any advantage, and lost more than 2,000 soldiers and horses in vain, so he had to retreat stupidly.

Yuan Nanjian got the news, was furious again, ordered Keming to be beheaded, and at the same time humbly apologized to Xincheng, hoping that Xincheng could give him an idea, so that he could turn defeat into victory and boost morale, but unexpectedly Xincheng shook his head and said: "Qiyu Da Mo left the branch, the little monk thinks that our army has suffered two setbacks, the sergeant has lost more than 20,000 people, and the morale in the city is low, and there is no chance to turn defeat into victory.

But unexpectedly, Yuan Nanjian immediately said angrily: "Er, this thief is bald, I thought that Er was a good person, but I didn't expect it to be so hateful, my Goguryeo has stood for hundreds of years, when Emperor Yang of Sui sent a million troops, they all won the battle, how heroic is Tang Taizong?" Why don't you just go home? It can be seen that the destiny is in me, how can I surrender to others and be at peace? If you don't look at the sincerity of the past, you will never be spared today! Don't get back now! ”

Xincheng listened to Yuan Nanjian's words, immediately sighed, and then slowly left.

After expelling Xincheng, Yuan Nanjian once again ordered the generals to go out of the city to attack the Tang military camp, but at this time, no one dared to take the initiative to ask for help, and they all became turtles with shrunken heads. Yuan Nanjian was furious and called the names of the two generals and ordered them to go out of the city to fight the next day, but unexpectedly the news came out that night that the two generals committed suicide.

At this time, the follow-up armies of the Tang Dynasty also came one after another, and the Tang army of more than 200,000 surrounded Pyongyang City like an iron bucket, and it was tantamount to a fool's dream to highlight the siege.
