"Angle 72, strength is strong! Let it go!" Zhang Wei, standing at the commanding heights of the city, shook the small flag and sent a flag-speaking signal to Liu Cheng, who was responsible for commanding the seven-pin cannons in the city.

There is a scale marked 360 degrees on the base of the seven-stop cannon. According to Zhang Wei's flag-language signal, Liu Cheng directed the 250 Yuanmu Nu and horse thief prisoners who were responsible for traction of the seven-stop cannon, turning the base of the seven-stop cannon to adjust the direction of the wooden pole. A basket was placed at the tail of the seven-stop cannon, filled with gravel as big as a goose egg.

After adjusting the angle and command, Liu Cheng first lit the net bag in the basket with a torch, and then gave an order: "Take it!"

Two hundred and fifty herd slaves and horse thieves pulled the rope at the same time. With the creaking sound of wooden gears, the lever was raised hard under the traction force of two hundred and fifty people, and raised it into the air with a basket full of gravel.

These gravels were all contained in a net bag. The net rope of the net bag was soaked in rosin and it burned when it encountered fire. The net bag that was burning with a raging fire flew into the sky like a huge fireball, smashing hard above the formation of the Later Jin army outside the city.

"What's the matter?" Looking at the two huge fireballs flying out of the castle, the Eight Banners soldiers who were sieging the city, the Ming army surrendered soldiers, the Han army flags and Baoyi Aha were all stunned.

The fireball flew into the sky, pulling out a parabola like a beautiful meteor. The net bag was burned in the air, unable to withstand the weight of the load of gravel. The gravel in the net bag spread out in the air, and it was like hail, which was spread to the once arrogant group of Later Jin soldiers.

Among the countless gravel stones as big as goose eggs, there were several large stones as big as millstones. With the call of the god of death, they fell into the middle of the attacking Later Jin army.

"Disast away!" Seeing that his soldiers were about to be smashed, Jin Youguang shouted anxiously.

The stones flying all over the sky were smashed down with the sound of the wind. In the face of this indiscriminate attack, whether it was the noble Zhengbai Banner heavy armored soldiers, the second-level Han Army Banners, the newly surrendered Ming Army, or the cheapest Baoyi Aha, they were treated equally in front of the gravels scattered all over the sky.

The stone was smashed down, and the Ming army surrendered soldiers in front were hit one after another. The stone was hit on the red-tassel hat. This soft hat was originally a military cap as a mark. It had no defense ability. When the stone hit, the whole head immediately faded. The head of the surrendered soldier turned into a scattered blood mist, and the body that had lost its head fell down twisted. Several Ming army surrendered soldiers picked up their shields and tried to block the falling stones with their shields. However, the stone hit the shield, and the wooden shield immediately broke and turned into scattered pieces of wooden boards, sweeping over the Ming army surrendered soldiers behind them like shrapnel.

Baoyi Aha who was following behind was also in trouble. The stones the size of goose egg fell down, and the whole head of the two Baoyi Aha was hit into the neck. Several Baoyi Aha were hit on the shoulder. They screamed in pain and jumped up. The ladders and trench bridges on their shoulders fell to the ground. On the side of the stone hit, one arm immediately softened because the collarbone and shoulder blades were broken, and one arm was scrapped on the spot.

A grinding stone mixed with gravel fell into the middle of Baoyi Aha, breaking a simple cloud ladder. The wood of the ladder broke into pieces and turned into pieces of various shapes and flew out. More than a dozen Baoyi fell down next to him screamed and fell down.

The Han army flag behind the coat was also in trouble. The shield in their hands was as fragile as paper in front of the flying stones. The Han army flag flag flag raised its shield to cover the flying stones. A flag flag dug up the shield in the direction of the stones hitting the stones. Only a dull collision sound was heard. The shield broke into several pieces, and the momentum of the stone that smashed the shield did not weaken at all. It hit the door of the flag kid. The lightning rod helmet on its head flew out, and the whole face immediately became concave. The brain mixed with eyes were smashed and splashed everywhere.

Another flag dean picked up a shield to cover it. A stone as big as a millstone hit the shield and knocked him to the ground like a shield. The stone pressed heavily on the shield, pressing the flag dean into a meat pie. The huge rock that landed on the ground jumped up again and knocked over another flag dean.

Even the heavy armored infantry of Zhengbai Banner who followed the last suffered. The archer who did not hold a shield behind was hit by a stone. The iron lightning rod helmet on his head was like paper in front of the falling stone. The stone hit the helmet, and the helmet was immediately concave, and even the helmet and brain were smashed. Some archers were hit on the shoulders, and the stone hit the shoulders, and one arm was immediately scrapped. The archer of Zhengbai Banner screamed and covered his shoulders and fell to the ground.

Even the giant shield and heavy armored soldiers in front were not much better. The giant shield in their hands could not resist the attack of falling stones. The stone as big as a goose egg hit the iron-faced wooden shield, making a sound of metal collision. The huge impact force caused the wooden boards inside the shield to shatter and splashed behind. A giant shield and heavy armored soldiers were covered with broken wood pieces, screaming, covering their faces and howled in pain.

There was also a giant shield and heavy armored soldier who used his shield to block the stone, but he felt that his arm had lost consciousness under the huge impact. After a while, he felt that his arm was in unbearable pain. It turned out that his left arm had been dislocated under the impact.

Another stone as big as a millstone hit two giant shield soldiers. The huge iron-faced shield had no resistance in front of the big stone. The two heavy armored infantry soldiers of the white flag immediately screamed and flew backwards. After falling to the ground, the shield covered them, and then the stone crushed past the shield.

Dozens of surrendered soldiers were killed and injured, and the surrendered general Jin Youguang's face turned pale. Originally, he was just a garrison at Hongshankou. The army of the Great Jin Kingdom arrived at Hongshankou. He was a hero and he surrendered to Huang Taiji with more than a thousand people under his command. Huang Taiji immediately promoted him to surrendered guerrillas. They would sooner or later be incorporated into the Han army flag, of course, the premise was that he would have someone under his command. If all the surrendered soldiers died, he would probably be disliked by him as a Baoyi.

Zhang Wei, who was standing at the top of the city, was responsible for commanding the attack of the seven-pin cannon when he saw a round of attacks. Most of the people who were killed and injured were Han people. Whether it was Baoyi Aha, Han army flag, or surrendered soldiers, they were not real slaves, but Han people. Zhang Wei felt a little reluctant: "The boss, most of the people we killed were Han people."

"Han people? Those are all Han jian! You deserve to die any more! Beat me hard!" Li Laoer roared angrily.

After all, the seven-pin cannon was not so fast. Taking advantage of the opportunity that the horse thieves in the city had not yet launched the second round, a large number of surrendered soldiers, Baoyi Aha, Han army flag and Zhengbai flag heavy armored soldiers rushed up and rushed to the city within thirty steps.

"Boom" two deafening roars, two heavy muskets aimed at the Zhengbai Banner archers behind and shot two one-two bullets.
