After a few days, Li Laoer also figured it out that the court refused to return to the Ming Dynasty at this time, which was a blessing for the failure of the enemy. Perhaps this was a good thing. What kind of power do those Shanxi merchants have? If they return to the court, it is difficult to prevent the secret arrows of civil servants hiding behind them, and they might be killed by them.

So what if he surrendered to Sun Chengzong? This time, Sun Chengzong was implicated by Yuan Chonghuan and was disliked by Emperor Chongzhen. Two years later, in the Battle of Dalinghe, Wu Xiang and Song Wei were defeated by the Qing army, and Zu Dashou surrendered. As a result, someone in the court impeached Sun Chengzong, and from then on, Sun Chengzong was forced to resign as an illness and go home to retire.

In real history, in the eleventh year of Chongzhen, the Qing army invaded again. In November, they attacked Gaoyang. Sun Chengzong, who was idle at home, led all the soldiers and civilians in the city to defend the city. In this battle, Sun Chengzong and his five sons, six grandsons, two nephews and eight nephews died in battle. More than a hundred people in the Sun family were killed. They were loyal and martyrs in the whole family.

Li Laoer followed Sun Chengzong and saw the white-haired Sun Chengzong standing on the front line, directing the civilians to work. Li Laoer admired the old supervisor very much in his heart.

The villagers brought back from the surrounding villages were successively placed in the shack outside the city. Sun Chengzong personally checked the situation of the porridge shed. Seeing that each of the villagers drank steaming hot porridge, he turned to the generals behind him and said, "Let's go back to the gunpowder workshop in the city."

"The supervisor loves the people as much as his son, and he is really kind and kind." Yang Guozhu said.

Sun Chengzong paused his head slightly and pondered: "Yang Junmen, the people will have the strength to work when they are full. The quality of the fortifications they are repairing is related to whether our Ming soldiers can kill more Jiannu at the lowest cost! Only by letting them eat enough can they work harder to build fortifications."

When he walked into the gunpowder workshop, Li Laoer saw the craftsmen preparing gunpowder. He saw the craftsmen mixing two portions of saltpeter, one portion of sulfur and one portion of charcoal together to make gunpowder.

"The supervisor, the gunpowder prepared in this way is probably not very powerful. The subordinates have a way to increase the power of gunpowder." Looking at the extremely unscientific proportion of gunpowder preparation for craftsmen, Li Laoer couldn't help but give an opinion to Sun Chengzong.

"Li Shoubei actually knows how to prepare gunpowder?" Sun Chengzong asked in surprise.

"Supervisor, the lower official has a musket, accompanied by gunpowder made by the upper and lower officials. You will know after a performance for the supervisor." After Li Laoer said that, he turned around and ordered Han Dashan to get the mesh gun he had made.

After a while, Han Dashan took Li Laoer's coax gun.

Sun Chengzong saw that the bullet gun was longer than the Ming army's bird gun, but not as long as the Lumi gun's barrel. In other aspects, it looked exactly the same as the bird gun from the outside.

"Please go to the shooting range outside, and the officer will personally supervise the gun test." Li Laoer bowed to Sun Chengzong.

After going to the shooting range outside, Li Lao Er took out a small bamboo tube from his waist, opened the lid of the bamboo tube, poured the gunpowder into the gun barrel, then picked up a projectile wrapped in silk, stuffed it into the gun mouth, and then pressed the projectile with iron strips. However, the projectile and the gun barrel were stuck very tightly and it was difficult to press in, so Li Lao Er picked up a small wooden hammer and beat the strips to compact the projectile.

After loading the projectile, Li Laoer turned the musket again, opened the cover of the medicine pool at the tail, took out the pointed-mouth pot from his waist, squeezed it into the medicine pool, and squeezed it in. Although the medicine pool cover was covered, then lit the fuse and hung the fuse on the hook.

After completing the loading procedure, Li Laoer retreated a hundred steps away from the target.

"Can this musket hit the target even if it hits a hundred steps?" Sun Chengzong is also a person who knows firearms, so he naturally knows how far a bird gun can hit.

The famous side van is the equipment used by Sun Chengzong's Vehicle Camp. Sun Chengzong invented the tactics of the Vehicle Camp. One Vehicle Camp has 1,728 three-eyed guns, 256 bird guns, 256 small Folang machines, 80 enemy-killing cannons, and 16 general guns.

Speaking of which, Sun Chengzong was also a master of using firearms. It’s a pity that the quality of the Ming Dynasty’s firearms was too poor and the quality of gunpowder was also poor. Therefore, the car camp tactics invented by Sun Chengzong, the car-mounted Folang machine cannon and the Dehuo Cannon could not penetrate the shield car of the Later Jin army at all!

Huang Taiji came up with a way to break Sun Chengzong's chariot camp, which was to use Baoyi Aha to push the shield chariot. Bayala soldiers and Gebush Xianchao soldiers rushed to the chariot camp with the defense of the shield chariot, and then suddenly jumped out to kill the Ming army.

The small Folang machine cannon in the checion weighs one pound of shells and loads one pound of gunpowder. It hits the shield chariot of the Later Jin army, which is like tickling the shield chariot.

By the same token, the vehicle-mounted Vandal Cannon fired a pound of projectiles, which could not penetrate the shield van at all.

Only the five-pound projectile fired by the General's cannon can penetrate the shield chariot of the Later Jin Dynasty. However, because the weight of the General's cannon is too heavy, it is difficult to maneuver the thousand-pound cannon. There are only sixteen doors in a car battalion, and it is impossible to be equipped too much. With just the sixteen cannons, it is impossible to deal with hundreds of shield chariots of the Later Jin Dynasty.

Therefore, to deal with the attack of the Later Jin army, the chariot camp also needs to arrange hand-to-hand combat soldiers such as spearmen, knife players and heavy weapon soldiers behind the chariot camp. They are called jumping teams. They rushed out from the hand-to-hand combat soldiers, withholding the heavy infantry of the Jin army in front, and then create opportunities for the three-eyed gunmen and bird gunmen behind to shoot and kill the Jin soldiers. In addition, a chariot camp of 6,000 people is equipped with cavalry of 1,600 people to cover the wings of the chariot camp and use the impact of war horses to deal with the heavy armored infantry of the Later Jin.

Sun Chengzong was originally a rare master of firearms in the Ming Dynasty. Naturally, he understood that the effective range of bird guns was only fifty steps, and even the effective range of Lumi guns could not reach a hundred steps.

But Li Laoer's next performance made Sun Chengzong stunned.

"Bang" a tongue of flame spurted out from the muzzle of the convex rope, and white smoke filled the air, and the target a hundred steps away swayed.

"I hit it! I hit the Red Heart!" The Ming soldiers who reported the target in front pulled out the target and rushed forward.

Sun Chengzong looked at the target and saw a transparent bullet hole appearing in the center of the wooden target two inches behind! Just now, the bullets of the musket pierced through the two-inch thick wooden target!

"That's amazing! Hitting the bull's eye a hundred steps away can also penetrate two inches of wooden boards! The power of this bird gun is so great!" Sun Chengzong stared at the target with wide eyes.

"I'm not sure about it when I return to the commander. The subordinates killed the captive chief Manguertai with this bird gun!" Li Laoer bowed.

"Why is your bird gun so powerful? This power is no less than that of the Flang machine!"

"Because Xiaguan's gunpowder is powerful." Li Laoer opened a small bamboo tube and poured the gunpowder inside on a piece of white paper.

Sun Chengzong looked at the gunpowder and found that the gunpowder was granular, cylinders as big as rice grains. So Sun Chengzong asked: "Isn't gunpowder powder? How did it become such particles?"
