One of the shooting competitions is a test of shooting distance. This is no longer a problem for shooters. It's a question of guns. Although some of the guns of the Qin State were marked with a ruler of more than 100 steps. But everyone knows that when the bullet reaches a hundred distances, it is all up to luck.

The shooting distance race begins. King Qin didn't pay much attention to this event. Because he also knew exactly how long the musket could reach.

"Aim." A musket sergeant shouted.

Seven contestants competed in this event. Moreover, there are only seven people. Five of them were armed with Lee's rifles. They want to rely on their own shooting experience and concentrate on the target at a distance of 100 paces according to a certain ballistic principle.

The other two have made big improvements. One person was equipped with a sight. The other person used a completely different gun. This is a single-shot rifle with a rotary pull-back latching method. Metal bullets are used. The shooter expressed great confidence in the weapon in his hand.

"Put." The sergeant shouted.

"Bang. Boom. Boom. "The sound of the musket was loud. The smoke of gunpowder obscured the shooter. The King of Qin symbolically pulled up the telescope to see the shooting of the target in the distance.

King Qin couldn't help but shake his head. The situation is very bad. I looked at three targets, and there was not a single bullet mark on them. King Qin was suddenly a little deflated.

"Let them report the target." King Qin ordered.

Immediately, King Qin waved his flag to signal the target.

The result was a little surprising to King Qin.

"Hey, hey. There was also one hit the target. Let's go and see. King Qin said to Zhao Gao.

"What's your name?" King Qin asked when he came to the shooter who hit the target.

"Report, Your Majesty. My name is Zheng An. The shooter saluted.

"Yes. Can your gun still hit a target at a hundred paces? King Qin asked.

"Yes, Your Majesty. Not only can you shoot a target at a hundred paces, but you can also shoot at a target with a score of three hundred steps. Zheng An said.

"Oh." King Qin was a little surprised. Three hundred paces, this distance is very tempting, if the musket can shoot at a target three hundred paces away, it is really amazing.

"Someone. Set up a 300-step target, and the outnumbered person will let you fire five bullets in a row. If you shoot three times, you will be awarded a silver medal. King Qin said.

"Look, Your Majesty." Zheng An made a gesture of please. He lay on the ground, and the people around King Qin were very close to King Qin. Because it's very dangerous on the shooting range. If danger arises. These people will use their bodies as a shield for the King of Qin to protect the King of Qin.

The 300-step target is set. Zheng An began to reload the first bullet. Although Zheng An's gun uses a rotary pull-back locking method. However, the way of supplying bombs is extremely backward. Requires a reload after firing. Finish unloading and reload another one. There is still a lot of room for improvement in this rifle.

"Bang." A crisp gunshot rang out. The muzzle of the gun did not emit as much smoke and dust, which was very different from other muskets. King Qin is very strange.

"Bang, bang. Bang. Bang. Four more gunshots followed. Zheng An shoots continuously.

"Shoot over." Zheng An knew that King Qin was uneasy and presumptuous by his side, so he took the initiative to leave the gun on the ground instead of holding it in his hand. The sergeant on the side inspected the guns under the instructions of the guards, and then collected them.

"How's it going?" King Qin asked.

"Quick, let's see how the shooting goes." Zhao Gao shouted. Then the opposite side reported the target. All five rounds hit.

After the King of Qin heard this result. Exultation.

"Someone is coming, and the widow wants to award Zheng An the Silver Medal." King Qin shouted loudly.

A distance of three hundred paces. It's an insurmountable distance. King Qin was overjoyed.

"That's right. Call Mr. Qin. The widow wanted him to see the new musket. Three hundred steps. "King Qin is overjoyed.

Afterwards, King Qin and Zheng An talked carefully. From the conversation, it was learned that the maximum distance of this musket was as high as 500 paces, but the bullet no longer traveled in a straight line. When shooting, you need to adjust a certain angle to hit the bull's-eye. After hearing this, King Qin was eager to try. He's going to use this new gun to hit a distance of five hundred paces. The distance of 500 paces is almost comparable to that of a crossbow. However, the weight of the gun is superior to that of the bow and crossbow. This made King Qin very happy.

King Qin shoots under the direction of Zheng An. The first is the target 100 paces away.

Shang Wen did not negotiate with Li Mu, and the two sides needed to digest the series of agreements reached in the previous paragraph. After receiving the order of the King of Qin. Shang Wen immediately rushed over.

"Mr. Qin, have you ever seen a musket that has fought three hundred paces?" King Qin asked directly.

Shang Wen was stunned for a moment. Three hundred steps, at most a distance of more than two hundred and eighty meters, this has naturally been seen. The farthest guns have ever seen, large sniper rifles. Capable of shooting at distances of more than a kilometer. If King Qin knew about this distance, he didn't know how to feel. "Hahaha. The widow asked the gentleman to see such a gun. King Qin said with a smile. Obviously, King Qin thought that Shang Wen had not seen it.

"Oh." Shang Wen reacted at this time. Hurriedly salute.

Shang Wen took the gun and began to examine it.

"Rotary pull-back latching. Use full metal bullets. Shang Wen looked at the gun and said.

"What kind of ammunition is your musket using?" Shang Wen asked very sophisticatedly. King Qin saw it from the sidelines. Zheng An immediately began to explain. And told all the causes and consequences of the manufacture of this gun.

Speaking of which, this gun also has a deep connection with pressure cookers. The pressure cooker has a certain locking mechanism. This kind of locking mechanism inspired Zheng An's father, Zheng Shan. His family came from Mengzhou, in the west of the Qin State, and he used to be a carpenter, and he knew how to make guns, first making butts, then slowly starting to repair guns, and finally began to make his own guns. This gun was done under the inspiration of a pressure cooker. But that's not the point.

Significantly, his other son, Zheng Ping, a student in the chemistry department of Qin State University, replaced smokeless gunpowder with the traditional black powder of the Qin state.

But when he heard about smokeless gunpowder, Shangwen wanted to know very much how the other party solved the fiber problem.

The answer he got surprised Shang Wen. In some parts of Mengzhou, there are a large number of shallows, that is, wetlands, and there are a large number of reeds in these wetlands, and these reeds have a kind of big stick before they bloom, and if you break them by hand, they are full of fibers layer after layer. This fibre is very similar to catkins, and although the fibre length is as short as catkins, it can be used to make fibers for smokeless gunpowder. The nitrified fibers are made into small pieces. The power of burning is very great.

Shang Wen smiled secretly in his heart. I paid all my attention to the catkins. Forget about looking for alternative fibers.
