Chapter 724 Encountered a Difficulty

Yu Sheng was also a little bit helpless, because he came here to study some kind of gun, and besides, the gun was manufactured directly according to the introduction on the blueprint, so he had to come here by himself.

But Yu Sheng suddenly thought that he didn't seem to understand this gun very well... The blueprints were all given to him by the system, so how could he know how this gun was made.

Thinking of this, Yu Sheng's expression became a little unnatural.

"System, system, have I published any books on gun manufacturing in the mall?" Yu Sheng immersed himself in the system and asked impatiently.

"Yes." The system replied: "The host can buy 50 books, may I ask if the host can buy it?"

"50 copies?"

When Yu Sheng heard the words, he was taken aback for a moment, then his expression brightened, and he couldn't wait to ask: "How much military merit?"

"50 points."

"50 points?"

Yu Sheng was a little surprised, and asked, "Why is it so cheap all of a sudden, isn't this in line with your style?"

Indeed, buying things in the past was extremely expensive, ranging from tens to hundreds, but I didn't expect that the price of buying fifty books would be so cheap.

"It depends on the situation." The system said slowly, "May I ask the host if he wants to buy it."

Yu Sheng was suspicious for a while, why did he suddenly feel that this system is priced at will by himself? Set as much as you want? Although there is no direct evidence, Yu Sheng still has this feeling.

"Buy, buy now." Yu Sheng said immediately.

"Didi, the host is buying fifty books."

"Didi, the host has consumed 50 points of military merit, and the purchase was successful."

"Didi, the host still has 570 points of military merit. May I ask the host if you want to continue buying products."

"570 points?"

When Yu Sheng heard this, he couldn't help taking a breath, and Yu Sheng asked in shock, "System, why did my military merit suddenly increase so much?"

"The host killed several people on Alcatraz,

In this way, 420 points of military merit are obtained, plus the previous 200 points of the host, so the host has 620 points of military merit, and the host has just spent 50 points on purchasing goods, and the host has 570 points left. "

"Damn, am I so rich?"

Yu Sheng looked overjoyed, he almost forgot that he had just returned from Alcatraz Island, so he must have a large amount of military merit, not to mention, those people in Alcatraz Island are not good people, it is already very scary to be able to get 420 points up.

This is really a sudden pie drop.

The rest of my life is a little bit exciting.

"System, integrate these books immediately."

As Yu Sheng's words fell, a lot of knowledge appeared in Yu Sheng's mind. This knowledge shook Yu Sheng's whole body. For a while, Yu Sheng felt dizzy.

This is the advantage of buying books in the system. As long as you buy them, these books seem to be engraved in Yu Sheng's mind. No matter what time it is, Yu Sheng will never forget what is in his mind.

For a while, Yu Sheng also had a great understanding of the structure of guns, some new materials, and some structural principles.

At the same time, this also made Yu Sheng understand how to bring out the maximum power of a gun. This made Yu Sheng a little surprised. Obviously, he did not expect it to be like this.

At this moment, Yu Sheng heard a call, which made Yu Sheng slightly stunned. Yu Sheng could not help but wake up from the system, but saw Fan Tianlei calling him.

"Yu Sheng, what are you in a daze for?" Fan Tianlei asked.

"It's okay." Yu Sheng chuckled and said, "Isn't he very curious about the weapons here? I didn't expect there to be so many weapons here."

Zhang Haiguo laughed when he heard the words, and said: "Here, there are all kinds of weapons, almost all the weapons that can appear in our country are here."

"Can you not have more?"

Yu Sheng couldn't help being a little shocked, all the weapons that could appear are here, which means that this laboratory is very big... This makes Yu Sheng also secretly surprised.

"Oh no……"

At this moment, a rush of voices resounded, and then, from outside, a person quickly walked in. This person was wearing a white coat and had long hair, but the long hair was tied up. This girl has exquisite facial features , looks very beautiful, just like a beautiful doctor.

This girl is called Li Xueqi, and she is very beautiful. Moreover, this girl is not a simple person, because she has a double doctorate. This year's grade is only 26 or 7 years old. This level is already quite powerful.

These days, there are not many double doctors, and this Li Xueqi graduated from a famous brand, so when Li Xueqi returned to China, she was transferred to work here.

"What's wrong?" Zhang Haiguo frowned upon hearing this, and said, "Xueqi, is there something wrong with our new materials?"

"There is indeed a big problem."

Li Xueqi looked serious, and said: "Professor Zhang, our new material is five hundred degrees worse in terms of high temperature resistance. If this material is applied to new weapons, it will be very dangerous."

"We have to find a material that can withstand high temperatures, and it can be fused with this material, as long as it can reach the predetermined temperature, but... I have found a lot of materials, and I can't do it, although some You can increase the melting point, but ... once the melting point is increased, the hardness of the material will decrease."

Li Xueqi's complexion was a little unnatural, and she was also a little anxious.

"Oh."

Hearing this, Zhang Haiguo frowned. They have been studying this project for a long time, and now they have made a huge breakthrough. If there is such a problem that traps them, they may have to study for a long time.

"Come on, let's go and have a look."

Zhang Haiguo didn't talk nonsense, so he said directly: "Xiao Zhang, you all come here too, just to be familiar with the environment of the laboratory."

"it is good."

There is no nonsense for the rest of my life.

At this time, Li Xueqi looked at Yu Sheng in surprise. Yu Sheng was wearing a camouflage outfit, and he looked like a soldier at first glance, but what is a soldier doing here? After all, this is a laboratory. Generally speaking, other people are forbidden to enter. Even if Yu Sheng is a soldier, he should not be allowed in.

Hearing what Zhang Haiguo said, and being familiar with the laboratory, is it possible that this person will live in the laboratory all year round in the future? This surprised Li Xueqi a little.

However, Li Xueqi didn't think too much about it, it was not up to him to decide who would come to the lab.

Immediately, everyone quickly ran towards the laboratory.
