At this moment, the thick smoke in front of the ruins blocked the view of both sides like a wall.

The smoke not only made the people on Li Muyuan's side unable to see the scene in the ruins at all, but also made the Jin army's view only see the edge of the ruins.

As for the battlefield where they were fighting, the generals of the Jin army could not see the battle situation on the smoke except for hearing the roar and slashing sounds.

Li Muyuan stared at the smoke thoughtfully while still nervously paying attention to the battle on the battlefield.

In front of him, his army was forward with three rugby teams holding cold weapons, and the remaining hundreds of night battle teams followed closely, rushing forward with their rapid lethal gunpowder weapons.

Although the number of Jin troops far exceeded theirs, their own army was extremely brave and killed the opponent's army, leaving behind a bloody road with corpses all over the field.

The soldiers' fingers were invincible, just like steel drills, constantly tearing and attacking the Jin army brigade of thousands of people!... But at this moment, a sharp whistle suddenly heard from the roof of the large library without any warning.

At this moment, Li Muyuan suddenly turned back again.

At this time, the expression in his eyes had become extremely sharp due to tension! This is not the first time that Li Muyuan has turned around. When he came to the fortification to direct the battle, he had looked back at the roof of the large library.

What exactly is there that makes the commander review frequently?

At this moment, when Li Muyuan turned around, he saw a flagpole standing on the four-story roof of the large library. There was a person hanging on the position where the flag was supposed to be hanging.

He was a Tongzhou army soldier with a light body and agility, like a monkey.

At this time, he was putting down the telescope in his hand, putting a whistle tied around his neck in his mouth, and blew it with all his strength! At the same time, the 100-person night battle team was fighting hard in the enemy formation.

After hearing the whistle, they made an incredible action in an instant... These people fell to the ground in an instant as if they were shot! When the whistle sounded, everyone could hear it clearly.

Especially the rugby players who were holding a fire axe in their hands and killing among the crowd.

The whistle sounded in their ears was very familiar to them.

The whistle sound was two shorts and one long. On the football field, this was the final whistle! For Li Yanyan and the others, this time the whistle sound was also the assembly call that Li Muyuan had already agreed with them.

When the whistle sounded, it meant that they were lying down immediately! Then, the moment more than a thousand people in the Ye Zhan team fell to the ground.

Behind the thick smoke wall rolling in the direction of the ruins, countless iron sands of the Fire Dragon Cannon were suddenly shot out like pouring rain!... At this moment, the roar of gunpowder burst into flames in the fire Dragon Cannon chamber was like rain hitting lotus leaves, so dense that it was impossible to tell.

Hearing the sound of the cannons, there were at least four hundred fire dragon cannons, and they fired heavy rain-like ammunition towards the Jin and Song armies who were fighting for the smoke! Each fire dragon cannon was filled with about two kilograms of iron sand.

These mung beans are made by Jinguo craftsmen poured melted iron into cold water and used sudden cooling.

This practice is called "fried beads" in the Jin army's arms factory.

Now these small iron balls are carrying strong kinetic energy. As soon as they come out of the smoke, they swept across the position where the two armies were fighting just now! They saw the Jin army brigade, still standing there, was knocked down to the ground like straw under a sickle.

During this volley, the large group of Jin troops who were still fighting desperately just now were hit by their own ammunition.

In an instant, only a few Jin troops who survived the disaster were left on the position! Before that, after a second or two in advance, the rugby players and the night battle team lying on the ground, were almost unscathed because of the early warning. Of course, these included those rugby players with great figures, Li Wanji, Li Yanyan and others, and even all the soldiers in the night battle team.

After seeing this scene in front of him, Li Muyuan breathed a sigh of relief.

After that, he immediately ordered all night battle teams to retreat quickly!... Seeing this, everyone may have to ask, what's going on?

Why did Li Muyuan know in advance that the Jin army would suddenly attack with the Fire Dragon Cannon when the two armies were fighting.

I know that they will defeat all the soldiers on the battlefield without distinguishing themselves from each other.

Even a lookout was placed on the upper floor of the large library in advance?

In fact, the Jin army's Fire Dragon Gunners took advantage of the two armies' hand-to-hand combat to raid this tactic behind.

During the battle for the ruins, it was used on a small scale by Wanyan Heda's army.

In this battle, Li Muyuan had long expected that as long as there was a hand-to-hand combat on the battlefield, the soldiers of both sides who were fighting for nothing would be covered and killed by the Fire Dragon Cannon.

Because the Jin army had an absolute advantage in terms of numbers, it would be a dream for them to exchange ten people for one of their own soldiers! So Li Muyuan placed a lookout whistle on the top of the flagpole on the upper floor of the big library in advance.

He held a telescope in his hand and a whistle in his mouth. When the Jin army used such a destructive move, he immediately issued a warning signal.

...In fact, the entire process of this matter is also extremely dangerous, because the time it takes for the Fire Dragon Cannon to fire the gunpowder twister to be fired is only about five seconds.

During this period, when the high-level lookout hand was observed, hundreds of pieces were blown by the gunners and ready to light the gunpowder twister, they would immediately issue a warning.

The troops who heard the whistle in front must also lie down immediately as the whistle sounds to avoid being killed by the fire dragon cannon.

As long as someone hesitates for a moment, among the Jin army that has been defeated in large numbers, countless soldiers, including Li Yanyan, will be killed and injured by Tiesha.

Fortunately, Li Muyuan made such preparations in advance and saved his troops the moment the Jin army fired the Fire Dragon Cannon.

This has caused only slight casualties in the current night battle squad.

At this time, the tall Jin army's Iron Pagoda soldiers were almost killed and injured by their own people.
