"The minister thinks that this time the envoys of the Six Kingdoms came to my Great Qin, it is already obvious that they are coming to target my Great Qin's weapons." Li Si first stabilized the question of King Qin.

"For these weapons, it is a sharp weapon of my Great Qin to sweep the six countries, such a sharp weapon should be kept a certain degree of concealment. When my Great Qindong sent a letter to Guguan, it was the time to shock the Six Kingdoms. While the six countries are still unable to adapt. You can quickly dominate the world. Lees said.

"Yes." King Qin nodded.

"Aiqing and the widow have the same opinion." King Qin said. Li Si was very happy to hear it, at least King Qin and his own ideas can be consistent, which shows that he can still maintain his status as the prime minister of Great Qin.

"However, under the city of Zhao Guoyun, the widow once showed Li Mu my Daqin's new firearms. What does Aiqing think? King Qin then threw out a tricky question.

"This ・・・・・・" Li Si really didn't think of such a problem. But now it's happening. I don't know why King Qin wanted to show it to Li Mu at that time. The combat power of Li Mubian's army is comparable to that of the Qin army. Now it has been shown to Zhao Jun. According to the habits of Zhao Jun and Li Mu, he will definitely make preparations. Moreover, the arsenal has ceased operations and is unable to produce firearms in large quantities. Li Si was really helpless when he encountered such a problem.

"Ignorance," Li Si said as he fell to his knees.

"Get up. This matter is not something that a prime minister can solve. King Qin said.

"I've already invited Wei Yu, Feng Quji, and Qin Shangwen. Let's sit down and have a good discussion. King Qin said comfortingly.

Wei Yi and Feng went to rush in.

"Meet the King." The two saluted.

"Get up. Everyone sat down together to discuss the matter of the envoys of the six countries. King Qin waved his hand and said.

King Qin saw that there was no Shang Wen, and knew that this person was busy, and it was estimated that he would be able to come after a while.

Shang Wen was further improving the musket artillery at this time. The first musket is still undergoing endurance tests. The results are coming soon. The barrel of the gun is already hot. It doesn't take long to see the results. As for the artillery. Shangwen decided to recast a door. The caliber of this gun was increased to two inches. The length remains the same for the time being. According to the original plan, Shangwen planned to start installing gun mounts after the casting of this artillery. There should have been an aiming system on the gun mount. This requires the artillery to cast an aiming pin when casting. Install the ruler on the back. After being mounted on the gun carriage, it is possible to adjust the height. This requires the gears to be coordinated with each other, and fixed. The gun carriage was to be mounted on wheels. There has to be something that can be fixed. But for the recoil after artillery firing. This problem cannot be solved for the time being.

Now the recoil of the artillery is eliminated with hydraulic pressure. In the current situation, it is clearly impossible. The tightness is not up to the mark. Shang Wen just needs to be like this. Shangwen tried to see if he could add rifling to the gun, or improve the shape of the shells. Shangwen began to talk to the foundry about the shape of the cannonball. After the foundry heard. Let Shangwen make a model to see. Shangwen used wooden sticks on the ground to draw the streamlined shape of a modern artillery shell. The caliber should be slightly smaller than the caliber of the artillery, but not too much worse, and this was done mainly to maintain a certain tightness of the artillery. At the same time, it is also more convenient to install. The foundry expressed understanding. You can give it a try. Shang Wen nodded.

Shang Wen was about to improve the casting process. Sensing that there was someone behind him, he turned his head and saw that it was Zhao Gao.

"Mr. Qin, I finally found you. Let's go. King Qin is in a hurry to summon you. Zhao Gao said anxiously.

Shang Wen hadn't opened his mouth to ask Zhao Gao anything, and Zhao Gao had already finished speaking in one breath.

"Oh, well. Wait a minute, I'll explain the matter. Coming right away. Shang Wen finished speaking and left. Shang Wen went to the foundry and told him, "Can you use iron abrasives to cast?" In this way, the mold does not have to be destroyed when the casting is completed. At the time of pouring. The inside of the iron mold is simply plastered with clay. Shang Wen originally wanted to talk about coal ash, but thinking that the foundry had never seen coal, he changed his words to something else.

The foundry nodded, and Zhao Gao was anxious. Shang Wen had no choice but to follow Zhao Gao.

Waited for the carriage. Zhao Gao drove away. Only then did Shang Wen notice that his clothes were already dirty and unpresentable. It is very disrespectful to see King Qin like this. I want to tell Zhao Gao. But it seems that something is very urgent. Shang Wen had no choice but to keep his mouth shut. I believe that King Qin will not blame.

Waited until the palace of King Qin. Shang Wen followed Zhao Gao to a palace. As soon as Shang Wen entered the palace, he saw three people. It's all Wenchen. King Qin sat on the side as if discussing something.

"Meet the King." Shang Wen saluted.

"Sir, why is he dressed like that?" King Qin apparently noticed Shang Wen's clothes.

"Sir, get up." King Qin realized that Shang Wen was still in the process of saluting, which was not good.

Shang Wen up. Said: "The minister is casting muskets and cannons. ”

"Oh. In this way, my Great Qin has licked new weapons again. King Qin said happily.

"Yes, in terms of range・・・・・・・" Shangwen was ready to elaborate on the specific situation. King Qin asked before Shang Wen could say anything.

"Sir, have you brought it?" King Qin asked.

"Well, not yet. An improved model is being cast. However, Her Royal Highness the Princess has already seen it. Shang Wen said.

"Oh. The gentleman sat down first and spoke. King Qin waved his hand.

"Thank you, the king." Shang Wen sat down. It looks like three people. Wei Yi had an expression of wanting to find out. Feng Qujian was the same, but more surprised. Li Si sat expressionlessly like an old monk.

"Sir, let's talk about it first," said King Qin.

"There are two types of firearms, smoothbore guns and smoothbore guns. Smoothbore guns have less range than bows and arrows. But it's power. At a distance of forty paces, it is possible to penetrate all the armor. The power of the artillery was about five hundred paces. More powerful than a long-range crossbow. Reload time. It's on par for the time being. But it's powerful. The minister has ordered people to improve muskets, artillery. It is estimated that it will not take long to see the real thing. Shang Wen said.

"Yes." King Qin nodded.

"Sir, take a look at this first." King Qin said and handed Shang Wen a copy of the recital. Shang Wen took it with both hands and opened it to take a look. From the few words he could recognize, Shang Wen probably understood. This is when the Six Nations heard that the Qin army was going north to fight. Sent envoys to congratulate them. However, in the recital, the word military general appears repeatedly. Shang Wen didn't understand what this meant. Shang Wen didn't understand what the mystery was for a while. In short, this matter is not simple.
