"This is the musketeer\" Yingyu didn't know when she came behind everyone. Everyone hurried forward to salute.

"See Your Royal Highness." Everyone bowed and bowed.

"No gifts, no gifts," said the princess.

"Let me give it a try." Yingyu looked very anxious, and didn't even change her language.

No one should have heard it. Shang Wen squatted on the ground to check the target. Thinking of the trajectory of the projectile in his head.

Yingyu grabbed the musket when he came up.

"Wait." Shang Wen hurriedly stopped after realizing that the musket had been taken away.

"The musket has not been tested yet. It is still dangerous now. Wait a minute. You are using it." Shang Wen snatched the musket.

Everyone returned to their original positions.

"I'm optimistic. This is the loading process of the musket. Nothing can fall." Shang Wen said.

Shangwen began to charge gunpowder, put in the projectile, compacted, and put a little ignition powder on the cauldron. Close the cauldron, then open the fire door and aim. Firing.

The projectile fired again. In turn, Shang Wen fired five times.

Ying Yu was eager to try. Shang Wen had to let him make a shot. Shangwen installed gunpowder and projectiles for her. Make all preparations. Give it to Yingyu to shoot.

\"Bang." The projectile flew out. The recoil of the musket made Princess Da Qin, who used the musket for the first time, felt very uncomfortable, and the projectile shot high.

Shang Wen fired Yingyu. Quickly grabbed the musket. Run over with the musket to check the impact point of the projectile.

Shangwen knows that this gun has not passed the experiment. It is how many rounds of projectile the barrel can withstand. This data must be available. If it is fired again, what should be done if there is a burst. I cannot bear such a responsibility. Therefore, after Shang Wen finished shooting, he quickly took the gun away. Can't do this anymore.

Yingyu's shoulder was hurt by the recoil of the gun. She didn't even know that the musket had such great recoil, and it was the first time she had come into contact with such a weapon. But think about it. This thing does not take much effort. As long as the filling is correct. It will be able to fire. Yingyu thought for a while, but still wanted to try, but Shangwen took the gun. Yingyu wanted to come forward and grab it.

Yingyu, who came to the target, wanted to grab the gun, but seeing Shang Wen holding it tightly, she had to take the opportunity to grab it. See the hole in the target. Yingyu stepped forward and took a closer look. Looking at the target pierced by the projectile and the big hole shot out behind it, Yingyu felt this kind of power called a musket for the first time.

Shang Wen carefully checked the penetration effect of the musket. In the process of shooting, the projectile obviously dropped. It seems to be improved. Mainly the airtightness of the projectile, and the barrel needs to be carefully polished. The overall structure is very rough. There is also the power of gunpowder. This must be improved. The projectiles cannot be made of iron, they are still relatively heavy for the time being, only lead-tin projectiles can be used. And the killing effect is much better than iron projectiles. Shangwen sees it.

"Well, I will stop here for the time being today." Shang Wen clapped his hands and said. "This gun must be tested. Don't use people to pull the trigger. Use a rope to tie the trigger. Do a durability test." Shang Wen asked a craftsman.

"Understood." The craftsman replied.

Shang Wen is not worried about Yingyu, this guy must go get a musket. Shang Wen stopped the princess.

"Princess. Princess." Shang Wen shouted.

Yingyu was planning how to steal the gun. I heard Shang Wen calling him.

"What's the matter?" Yingyu turned around and said.

"Princess, the musket has not been tested for durability. Don't move it. In case of danger, it's not good." Shang Wen said.

Yingyu felt that her mind was seen through.

"However, there is one more thing. The princess may be interested." Shang Wen continued.

"What?" Ying Yu asked.

"Artillery." Shang Wen said.

After Shangwen finished speaking, he began to gather a group of craftsmen to discuss how to cast the artillery. Shang Wen's idea is simple, that is, to use Qin Guo's skillful casting skills in casting bronzes to create a powerful artillery.

The barrel of the artillery is made of copper, and the size is also realized by Shangwen. The length is about thirty feet and the caliber is one inch. The diameter of the projectile is below the caliber, which is easy to install. Shangwen asked the foundry if there was a problem. After the foundry took the drawing, he nodded, yes. Shangwen started casting. However, there is one point that Shangwen emphasizes. When casting, the muzzle of the gun barrel should be poured upwards, so that the best part of the copper water can be poured to the place where the gunpowder pressure is the greatest. Shangwen hereby emphasizes the reason for casting. The foundry expressed his understanding.

Casting molds and melting copper water is a boring thing. But Shangwen wants to guide on the sidelines. It's late at night. The impatient princess left early. Shang Wen waited quietly, watching the high temperature melt the copper bit by bit. Pouring, cooling, and removing the mold. Polished, overnight effort. A bronze artillery was built. Shangwen knew that this artillery could not hit very far, because it was a smoothbore gun. The casting process is relatively simple. The shells are all stars, not the streamlined projectiles of later generations. This requires progress, step by step. In order to achieve the results of later artillery.

Four people carried the artillery to the shooting range. Place the artillery in a previously dug pit. Adjust the angle. Shang Wen simply aimed. Then began to load gunpowder. Tamping and filling the projectiles. Then place the igniter and the fuse.

"Everyone cover your ears." Shang Wen exclaimed.

"Let it go." Shang Wen lit the fuse with a torch.

"Boom." There was a loud noise. Shangwen's ears were buzzing. The projectile flew out, but the target did not hit, but hit a piece of land in front of the target.

Shangwen took a visual check. The target position I set is really 500 steps, but the hitting distance is still a certain distance away from the target. It seems that the range needs to be improved. Especially gunpowder, rifling, and shells. At present, the actual combat effect of such artillery is not obvious. Shang Wen thought in his heart.

The huge sound awakened the princess directly. Shang Wen had already begun to check the power of the measuring artillery at this time. The distance of the shells entering the surface is quite deep, indicating that there is still a certain degree of power. Although the distance is not as good as that of a long-range crossbow, its power is greater than that of a crossbow. Mainly speed. This speed is incomparable with crossbows. In terms of loading speed, the artillery is slightly inferior. The mobility is not as good as the crossbow, but these shortcomings can be improved. Just be willing to improve. Entering the battlefield in the future, this must be a powerful weapon. Siege weapon. No city in the Warring States Period could withstand the fierce bombardment of artillery.

The craftsmen were surprised by the power of the artillery, but some people also noticed the shortcomings of the artillery. However, they had a consensus that the artillery could be improved. After all, this is only the first time artillery has appeared.
