Iron lock pass, as the name suggests, is to iron lock pass, the iron here refers to the iron chain, to put it bluntly, it is to use the iron chain on the river surface to pull, forming a line of defense, hindering the ship from crossing the river, playing the role of isolation.

When the ship is blocked by iron chains, the soldiers behind the iron lock will continue to shoot arrows, throw stones, etc., to suppress the enemy and force the enemy to retreat.

This is the battle strategy of the Iron Lock, which is simple but very effective.

Wang Xiaobo also knew this, so he decisively gave up the idea of smuggling, and began to concentrate firepower to attack, and gradually, with the advantage of numbers, the Shu soldiers slowly forced Yang Lie's army on the iron lock to retreat.

This is the tenth time that Wang Xiaobo has forced back Yang Lie's army, and the previous nine times will be counterattacked by Yang Lie every time, but this time, Wang Xiaobo has already prepared.

Taking advantage of the fact that Yang Lie's army was suppressed by firepower, Wang Xiaobo waved his hand, and an exceptionally large ship was pushed into the water, and rushed up against the iron chains on the river, and actually broke three iron chains at once.

And the big ship still came with the same momentum, and came straight to the fourth chain.

When Yang Lie saw it, he couldn't help but be very anxious, and used catapults and fireballs to attack the big ship, but it didn't have much effect.

At this time, he saw that the big ship was covered with a layer of iron sheets, completely ignoring the attack of the Song army, and it was precisely because of this layer of iron sheets that the bow of the ship was protected, which made the Shu soldiers break the three iron chains at once.

"It's not good, I'm afraid the chain can't be saved." Yang Lie thought to himself.

Sure enough, without waiting for Yang Lie to come up with a way, after a few strokes, all the remaining iron chains on the river surface were broken, and all the iron chains fell into the river, and they were no longer visible.

Yang Lie was in a hurry, and was about to order the withdrawal of the army and temporarily abandon the iron lock pass, when suddenly, a loud noise sounded behind the Shu soldiers.

"Boom!"

This sound, like thunder, shocked people's hearts, Yang Lie looked at it violently, and saw that among the rear army of the Shu soldiers, there was a curtain of water, as if someone had stirred the river.

He even saw a large plank, which seemed to be the plank of a certain ship, that had also rushed into the sky.

Suddenly, Yang Lie seemed to think of something, and a smile appeared on the corner of his mouth.

"Order, go back to Yun'an City." Immediately after, Yang Lie ordered loudly.

The Song soldiers retreated directly, and the Shu soldiers behind them did not dare to chase after them, but retreated one after another to check the situation.

In this way, the only remaining 2,000 troops on Yang Lie's side saved their lives, otherwise if they were pursued by the Shu soldiers, I am afraid that these 2,000 people would die on the river sooner or later.

Half a day later, Yang Lie and the others returned to Yun'an City safely, and it had been fourteen days since he left the last time.

Lu Yiping was the first to greet him, for this general who had delayed for nearly half a month for the entire Yun'an County, Lu Yiping is now grateful from the bottom of his heart, shushing the cold and asking for warmth, extremely thoughtful.

I don't know, I think he has a special relationship with the two, after all, men and men are also a fashion in this era.

After having dinner with Lu Yiping, Yang Lie began to prepare to take over the defense of Yun'an County, after all, he is a professional general, much more powerful than the garrison general of Yun'an County, and with this towering Yun'an City, Yang Lie is confident to hold on for another half a month.

And half a month later, the army of the court is bound to attack, and Wang Xiaobo is attacked on both sides, so he naturally can't take care of Yun'an County.

And if Wang Xiaobo is finally defeated by the imperial court, maybe Yang Lie can take advantage of this to sneak attack Shu and make a great contribution, maybe he can also use this to make a knighthood.

Thinking of this, Yang Lie couldn't help but smile, and he also knew that all this was thanks to the person who created a shock in the rear of the Shu soldiers.

Yang Lie is not a stupid person, on the contrary, he is still very smart, and vaguely, he has already guessed the identity of that person, but since that person did not show up, Yang Lie temporarily suppressed the idea of meeting that person.

Yang Lie didn't know that when he guessed the identity of the person who helped him on the city wall, the person who helped him looked at him not far from the city wall.

Needless to say, the only thing that can create an explosion in the Great Song Dynasty is the Shenwei Thunderbolt, and the Shenwei Thunderbolt is only owned by two people in the Great Song Dynasty, and that is Zhao Gu and Zhao Guangyi.

At the beginning, Zhao Gu thought that the Shenwei Thunderbolt was amazingly powerful and would be slowly applied in wars and civil projects, which was also his original intention to make this thing at the beginning, but he didn't expect that a few years later, this thing still did not circulate, and even in the forbidden army, there was no reserve of Shenwei Thunderbolt.

The reason for this result can be imagined, it must be that Zhao Guangyi saw that the power of the Shenwei Thunderbolt was amazing, and he was afraid that someone would use this thing to his detriment, so he kept it secret, except for Zhao Gu, the creator, no one else could see this thing at all.

I have to say, Zhao Guangyi is really stupid enough, does he have to use Shenwei Thunderbolt to kill people? His perception is really ridiculous, human society is constantly improving, if there is a new thing, like he hides it, what development will mankind talk about, and what future will the Great Song Dynasty talk about?

In fact, Zhao Gu has always felt that fortunately Zhao Guangyi is an emperor, no one dares to do anything to him, otherwise with his character, he would not know how many times he has been beaten to death, he is really too indebted.

And the reason why Zhao Gu came to Yun'an County and helped Yang Lie was naturally because he had his plan.

First of all, although the Great Song Dynasty now seems to be powerful, but it is a mirror, everything is not real, the national strength of the Great Song Dynasty is actually much worse than in previous years, but the territory is much larger, if the independence of Shu is allowed, the blow to the Great Song Dynasty is absolutely fatal, Zhao Gu is here, it is to prevent the independence of Shu, and even destroy Shu, so that the Sichuan Gorge Road returns to the Great Song Dynasty.

And Yun'an County is a place where soldiers must fight, and it is also the best place to defeat Wang Xiaobo, so Zhao Gu naturally came here.

And Yang Lie is also quite capable, Zhao Gu helped him, and also had the intention of winning over this person, although he seemed to be majestic in the court, but he did not have a descendant or helper, if he could win over Yang Lie, it would be a kind of help.

After walking around the county town of Yun'an County at random, Zhao Gu came to the Baiwei Restaurant here and found the local person in charge.

This person's surname is Zhang, his name is Zhang An, and he is also a descendant of Li Danran and Hao Baibai, otherwise they would not have been allowed to come to the chaotic Sichuan Gorge Road.

After seeing Zhang An, Zhao Gu checked the latest information of Yun'an County for the first time, and after knowing everything in his chest, he lived in Yun'an County under Zhang An's arrangement, waiting for Wang Xiaobo to come to attack the city.

He wanted to see what the biggest rebel leader in the early Song Dynasty looked like.
