Wu Sangui stood at the head of the Xiluo City in Shanhaiguan, holding a thousand-mile mirror to observe the movements of the Shun Army on the other side of the Shihe River. The Guanning Army was also equipped with the thousand-mile mirror. At that time, Xu Guangqi and Sun Yuanhua obtained a batch of thousand-mile mirrors from the Portuguese missionary, and some of the thousand-mile mirrors remained in the Guanning Army. Some of the thousand-mile mirrors were taken to the Later Jin Dynasty by Kong Youde and others after the Wuqiao mutiny.

Just as Wu Sangui was holding a thousand-mile mirror to observe the movements on the other side, he suddenly heard a dull "bang" sound from the opposite side. He saw a stream of white smoke rising from behind a dirt platform opposite, and a black iron ball rose into the air, pulling a high arc in the air, flying straight towards the top of Shanhaiguan where he was.

"What is that?" Wang Yongji, who was standing next to Wu Sangui, was shocked.

"The General Wang Zheng does not need to panic. This is a bombardment by the thieves. The thieves don't know what kind of artillery cannons are, and they are bombarded four miles away. The thieves will definitely not hurt me at all. The thieves are just a group of mud legs, so how can they know how to fight the cannons? They can't shoot the cannons at all!" Wu Sangui said with a smile on his face.

But soon, Wu Sangui's smile froze on his face: he saw the big iron ball getting bigger and bigger in his eyes, and finally hit the head of Xiluo City. Wu Sangui turned his head and saw that the big iron ball was actually landing about two feet away from a twenty-four-pound red artillery cannon position at the entrance of the city. The huge shells hit the bricks on the ground hard, making a loud noise. The bricks on the ground were shattered and splashed like shrapnel. Three Guanning Army gunners near the gun position were hit by the broken bricks and fell down screaming.

One of the gunners was the worst. Countless bricks hit his face like shotguns, and the whole face suddenly turned into pockmarks. The gunner screamed and covered his face and fell to the ground, donating blood to flow out along his fingers.

The landed shells smashed a large area of ​​the city, bounced high again, rolling in the air, flying towards the group of Guanning soldiers standing on the top of the city.

"Run quickly!" The Guanning Army infantry guarding the city screamed and fled in scattered, but the shells suddenly changed their trajectory, hitting the back of a Guanning Army soldier who had no time to run away. Wu Sangui saw with his own eyes that the soldier suddenly disappeared in front of him, turning into a scattered blood mist. After the shells smashed a soldier, they fell to the ground and smashed a piece of broken bricks and stones, knocking down two Guanning Army soldiers next to them. The landing shells bounced up again and flew towards Wu Sangui.

Wu Sangui was not calm now, so he quickly pulled Wang Yongji and ran back. The shells were like eyes, chasing Wu Sangui and Wang Yongji's butts.

However, the shells did not hit Wu Sangui and the others, but fell three steps behind them and hit the ground heavily. The splashed brick fragments flew everywhere, knocking down the five Guanning soldiers around. The landing shells bounced up again, but this time the force was almost exhausted. The shells were not bombed high, and they only bounced less than three feet high and then landed on the ground, rotating and rolling on the top of the city.

Seeing that the shells were no longer bounced, a Min Zhuang, who assisted the Guanning Army in defending the city, curiously stabbed the shells spinning on the ground with a long spear.

"Dangerous! Don't touch it!" A Guanning soldier shouted.

But it was too late. The spear in Min Zhuang's hand had already touched the rotating shell. The spear broke into several pieces like chopsticks made of ceramic tiles and flew out in scattered ways. The Min Zhuang was hit by the broken gun rod. The gun rod penetrated from the front and came out from the back. Min Zhuang screamed and fell down.

The iron spear heads were all shattered, and they shot like shrapnel. Two Guanning soldiers next to them immediately fell into a pool of blood.

"What a great artillery shell!" Seeing this situation, Wu Sangui gasped. The thief army on the opposite side accurately hit the city with just one shell, and the landing point was very close to his twenty-four-pound red artillery cannon position, causing more than ten casualties on his side. This artillery was shot too accurately, right? It seems that there are experts in the thief army!

The shells that landed on the top of the city had completely stopped moving. A Guanning soldier walked forward and reached out to pick up the shells. However, before his fingers could approach the shells, he felt a burning heat. He was so scared that he quickly retracted his hand.

At this moment, another dull sound of cannons came from the opposite side, and another shell flew up toward the city of Xiluo City amid the screams of Guanning Army at the entrance of the city.

The shell hit a squat above a maid wall on the top of the city wall. The entire female wall collapsed in a large area, and the crushed bricks and stones splashed everywhere. Fortunately, all the Guanning soldiers had already run away, so they did not hurt anyone. After the shell smashed the maid wall, it bounced high and flew towards the arrow tower on the top of the city.

With a loud "crash", the shells hit the arrow tower, smashed the doors and windows, and flew into the arrow tower. Only a series of wood and bricks and stones were heard in the arrow tower. The shells penetrated the arrow tower, flew out from behind, and hit the female wall behind the city wall.

The soldiers of the Ning army poured a bucket of water on the shells that had fallen on the ground. When the temperature of the shells dropped, the soldier picked up the shells, held the shells in both hands, and presented them to Wu Sangui: "Qijianmen, this is the shells of the bandits."

Wu Sangui was stunned when he saw the shell: I saw that the shell was so big, and the shells of his twenty-four-pound red cannon were already big enough, but compared with this shell, it was a terrible witch. It was as big as three of the twenty-four-pound shells. Wu Sangui felt that the difference was how did the thieves hit such a large shell on the top of the city? So how big should the cannons of the thieves be?

The two red cannons that fired twenty-four pounds of shells in Guanning Army were already weighing more than 5,000 kilograms, and such shells weighed at least more than 60 kilograms. So how big should the cannons that fired such shells? Wouldn't they have to be more than 15,000 kilograms?

The giant cannon with a weight of more than 15,000 kilograms is simply unimaginable! If Wu Sangui knew that the cannon that fired these huge shells was only more than 1,000 kilograms, he wondered what the expression on his face would be like?

Wu Sangui ordered: "The giant cannons of the thieves army are loading slowly, and fire in the direction of the mound! Be sure to destroy the giant cannons of the thieves army!"

The Guanning Army gunners at the top of the city nervously controlled the Red Barbarian cannons that had already been loaded with gunpowder shells. Several skilled gunners used rulers, triangle plates and other tools to calculate. These calculation methods were handed down by the Franians brought by Xu Guangqi and Sun Yuanhua back then. After the skilled gunners were calculated, they could shoot very accurately. It is said that during the Yuan Chonghuan era, Lao Yuan discovered the position of the Lao Nu's banner and ordered the bombardment. Rumors said that the gun killed Lao Nu.

Later, this incident became a legendary story in the Guanning army and a major achievement of Yuan Chonghuan.

In fact, if you think about it, you will know that killing Lao Nu is impossible. With the touching accuracy of the cannon back then, how could it be possible to accurately hit a target five miles away? Although the twenty-four-pound red barbarian cannon can reach about five miles, five miles is the maximum range, and the effective range is about three miles. Even if it is within the effective range of three miles, it is very low probability to hit the target accurately. If you want to hit the opponent's main general without a flower bullet, it is almost the same as the probability of a plane crash in later generations, or the probability of a train crash is similar.

What is the probability of death in a train? Even if something happens to a train, the car you are in may not be in trouble; even if the car you are in may happen in this train accident, you may not be in trouble. The probability can be said to be so low that it is negligible.

What's more, after the old slave was shot, he could still jump to Korqin Mongolia for several months. If he was hit by a twenty-four-pound shell, he would turn into pieces on the spot. Even if he was touched, he would at least have no arms or legs. He could still jump to Korqin Mongolia for three months? It was obviously impossible.

Zhao Peng, who was standing on the watchtower, found that the gunners of the Guanning Army at the entrance of the city were busy. He quickly sent out a flag-speaking signal: "Be careful, the thief of Wu is about to bombard the earth platform! Retreat quickly!"

Li Zicheng and others received a reminder from the personal soldiers behind him and hurriedly retreated from the earth platform.
