After listening to the questions pointed out by Wang Haoran, Supervisor Ye was too big, how could he not think of these problems? But he tried his best to solve it, and the sniper rifle in front of him, that is, the length of the barrel was shortened to make it a bit decent.

After listening to Supervisor Ye talk about the solution he had tried, Wang Haoran said: "The barrel must not be too short, otherwise the range will not be much." It is also not possible to increase the size of the inner hole because the inner hole of the barrel is not round, and it is fundamental to solve the problem of the inner hole is not round. The inner hole you pulled out is not round, it may be that the inner hole and the outer circle are not centered when it is cast, resulting in a non-uniform wall thickness, so that the distance of the barrel rebound is not uniform, you can rough it first and then finish it. ”

After Wang Haoran reminded him, Supervisor Ye also felt that it was very likely that this was the reason, and after asking Li Shimin for instructions, he left in a hurry, wanting to try what Wang Haoran said.

While waiting, Wang Haoran mentioned the copper mine to Li Shimin, his iron ore was almost finished, and the people in the cottage were looking forward to Wang Haoran finding a new mine to have a job.

"The matter of copper ore is the foundation of the country, and I can let you join in helping to mine it, but the use of copper ore required for your research must be reported to me in detail."

What Li Shimin meant by assisting in mining was to let Wang Haoran help him mine copper ore, and the copper ore mined still belonged to Li Shimin. Wang Haoran is also very satisfied, the people in the cottage have a livelihood, which can be regarded as fulfilling his promise to those people in the cottage, and he can also have copper ore for research, which is extremely beneficial to the production of steam power heads, and the pistons, shaft sleeves, etc. are made of copper and are extremely durable.

After discussing the copper mine, Li Shimin mentioned Wang Haoran's marriage and said: "Your marriage with Princess Nanchang, because your current status is too low, the Ministry of Rites has not yet negotiated a charter, so I decided to grant you the title of Chang'an County Bar first, so that the Ministry of Rites can negotiate the charter as soon as possible." ”

Conferring the title of Wang Haoran so early made Li Shimin a little painful, Wang Haoran is only fifteen years old this year! With this kid's ability, there will definitely be a lot of meritorious deeds in the future, what if Wang Haoran reaches the top of the title many years later, and there is no reward to be rewarded?

Wang Haoran thanked him, in fact, the title is dispensable for him, judging from Li Shimin's consistent behavior, it is estimated that Wang Haoran's county barony will not even have it, it is just a high hat.

After a long time, Supervisor Ye finally came over with the barrel of a gun and said with a smile: "Your Majesty, Prince Wang, this time it must be okay." ”

Li Shimin saw that Wang Haoran took the barrel and checked it and didn't find any problems, so he asked Supervisor Ye to replace it and try it.

Supervisor Ye skillfully adjusted the sniper rifle, and then the three of them came to the shooting range together for experiments. Supervisor Ye often experiments with sniper rifles, and now he seems to be a good sniper. Supervisor Ye lay on the ground and faced the scope, and after some adjustment, he shot it.

After an explosion, Li Shimin inspected the target more than 20 zhang away with a telescope, and said with satisfaction: "Yes, less than two finger widths away from the bull's-eye, try another shot." ”

Then Supervisor Ye tried a few more shots, and the results were all good. Li Shimin handed the telescope to Wang Haoran again and said, "Look at it, it's okay to have this quasi-head, right?" ”

Wang Haoran looked at the target with a telescope, and the accuracy was okay, after all, Supervisor Ye was not a sharpshooter.

Supervisor Ye and Wang Haoran came to the telescope to look at it and said: "Your Majesty, Wei Chen has not recalibrated these shots, and the results calculated according to the formula are aimed at the bull's-eye. ”

"It doesn't matter, every gun, and even everyone's shooting action is different, as long as each sniper rifle is dedicated to a special person in the future, the sniper will naturally adapt to his own sniper rifle. Another point is that the sound of this sniper rifle is too loud, and Supervisor Ye can develop a silencer device to install on the muzzle, as long as he finds the right material and construction form, he may be able to reduce the sound. ”

"I wonder if the prince has a drawing of a silencing device?" Supervisor Ye hurriedly asked, he shot a few times just now, and each time his ears buzzed.

"Nope." Wang Haoran also knows a rough idea of the silencer, and how to design it still needs to be studied.

"Can you bother the prince to study it?" Supervisor Ye pleaded, now that the sniper rifle is basically formed, after a few more experiments, presumably Li Shimin will let Supervisor Ye mass produce it, and then he will be busy, and he will not have much time to study the silencer.

"I'm busy!" Wang Haoran decisively refused, in fact, the silencer is also very simple, just let Wang Haoran study it for a while to make it, but Wang Haoran doesn't have so much free time now, he still has to take the charity on the right track so that the four women can easily take over, and drink the wedding wine, this month alone to drink the wedding wine has to drink four times, and when you drink your own wedding wine, how can you still bother with the silencer?

"Is it hard to study silencers?" Li Shimin asked thoughtfully.

"It's not that easy to figure out." Wang Haoran was worried that Li Shimin would force this matter on himself, so he told a little lie, even if anyone studied it in less than half a month in the future, Wang Haoran could still exclaim: It took half a month to study it, isn't it difficult?

"Then I'll leave it to the research institute to study." Li Shimin has a plan, isn't Li Tai always clamoring to go to Puzhou for training? Okay, I'll let you go when the silencer is developed. It's not that Li Shimin underestimates Li Tai, but even Wang Haoran finds it difficult, he doesn't think that Li Tai can study it in a year and a half, and during this time, Li Shimin can slowly dispel Li Tai's mind of going to Puzhou for training.

"However, if Tai'er goes to you for help, you must not agree, and you must not say that I signaled you to do this, otherwise, I will not be able to spare you!" Li Shimin added.

Wang Haoran originally thought that it would be better to hand over this research to the research institute, so he didn't have the heart to delve into what conspiracy Li Shimin still had. But when he heard Li Shimin's words, Wang Haoran thought of Li Shimin's ghost idea, and almost burst out laughing, but he didn't expect that he had inadvertently done Li Tai a big favor. It seems that after he gets married, he has to go to Puzhou for refuge in a hurry, otherwise after Li Tai takes the silencer and hands it to Li Shimin, Li Shimin will definitely be so angry that he will kill his heart.

"The grass people obey!" Wang Haoran said firmly, Li Tai is not stupid, can he still help with a gadget like a silencer? Now not only Li Shimin is worried that Li Tai will develop a silencer too early, but Wang Haoran is also worried! What if Li Tai researched the silencer and handed it over to Li Shimin before he left Beijing? (To be continued.) Mobile phone users, please browse and read, a better reading experience.
