Obviously, Trest definitely has his reasons for playing like this, if Zhu Cheng completes this exam smoothly, where will the face of the library system go? The first two levels allowed him to get two-level borrowing privileges, and there are more than 13,000 contribution points, and if the third level is passed ordinarily, there will be suspicion of cheating.

Although, he has mentioned many times that there are already some things that do not match his identity as an invigilator, but now the third level of the exam is just as Zhu Cheng said! The difficulty of this exam is beyond his imagination!

"If you drop out of the exam now, based on your current test scores, you should be able to get an upper-middle exam rating, which is also good! The project of the third level is really a little... Perverted! ”

Just like the Enneagram personality analysis, Zhu Cheng's character is a perfectionist, and it is true that this exam question is difficult, but he does not intend to give up, giving up represents imperfection and losing generous rewards!

"It's still going to be an exam! I feel like I can finish this project! ”

Zhu Cheng clenched his fist and puffed himself hard, which was both a target and a test! If you successfully survive this hurdle, it is to clear the clouds and see the dawn, if you can't pass, it is just a matter of ignoring everyone. From Trest's words, Zhu Cheng already felt that the future situation and competition must be very fierce.

"I've thought about it. Let's get started! ”

Trester made a gesture of please, signaling that the main city could start the third level of assessment. The difficulty of this project is very high, especially for Zhu Cheng, who is accustomed to artificial intelligence and big data computing, it is the biggest challenge.

Because of the insufficient expansion of the brain domain, the activity of neuronal cells is insufficient, and the computing power is weak, this stage must rely on the cooperation of supercomputers and special computers to complete experiments and calculations.

Zhu Cheng has been using scientific calculators since high school, and he has never manually calculated some complex arithmetic problems. Now he was faced with an important issue.

The third level of Trest is a very strange topic, this topic is called building missiles with bare hands!

This perverted topic made Zhu Cheng's jaw drop to the ground, but he felt that it was understandable! This level examines Zhu Cheng's computing ability and accurate hands-on ability!

Of course this is not with bare hands, and certainly not with both hands! It's a false proposition for any engineer in the world to come over!

It's just that the tools provided are very backward, so backward that Zhu Cheng has no clue at all!

The first level is the test paper level. The second level is the experimental level. The third level is the project level! It is not only Zhu Cheng's knowledge, hands-on ability, but also design thinking that is examined! At this point, he is not very good at it.

"Do you care about the food? If this project is not completed, what should I do if I am hungry? He suddenly changed the subject, and said with a smile, this question he wanted to ask from the beginning, because at that time, as soon as he passed through the two-way door, he thought of the problem of bringing his own dry food, and it happened that the master's house was here now.

Trest has a black line, what the hell! When he thought about it, he understood that Zhu Cheng was just diverting his attention and not letting himself be so nervous.

"It's a virtual world, and on the Type A exam, there's a life cycle device, which is enough to keep your vital signs healthy, and you're at ease."

"Are there any attempts?" Before he started, he asked another question, he didn't think he could succeed at the first time, no project could be completed at one time, which is also a false proposition in scientific research!

Trester nodded and said, "There is naturally no limit to the number of times this can be done!" Until the challenge is successful, or you lose patience and give up. ”

This privilege still needs to be had, and the third level is not the knowledge in the books examined, but the knowledge involved in the first-level books of the real exam. This proposition of rubbing nuclear bombs with bare hands is already extremely ghostly, and if you limit the number of times, it will be difficult for a strong man, and it will be deliberately difficult.

Zhu Cheng still didn't step forward, he was anxiously looking at the pile of materials on the test site. His expression was very embarrassed and he asked, "If I die in the examination room, what will happen to me in reality?" I haven't seen this A-type examiner after all. Is it reliable? ”

He really wanted to know the answer to the question, after all, he was just here for the exam, and if he had to pay such a price, he would have to choose between perfection and life.

This multiple-choice question is very easy to do, and fools know how to choose.

"You're thinking too much! This is a virtual world, that is, the missile that was built was blown up. The impact on your reality is minimal, don't worry. Trest answers the question, the desire for life is the instinct of intelligent beings. Fear of death is not a reason to be ridiculed.

"Then I'll go."

Zhu Cheng spoke, and slowly came to this production area from the place where he was standing, missiles are a very complicated process, and what Zhu Cheng wants to do with his bare hands is of course a powerful intercontinental missile!

Of course, ICBMs are extremely complex, and if he were to complete an ICBM by himself, with a backward machine tool and a backward cutter!

Even if you die of old age here, there is no possibility. What he needed to do was a relatively simple warhead.

The structure of the intercontinental missile is complex or there is a context to follow, the most important part is the warhead, also known as the warhead, the intercontinental missile has to fly more than 8000km distance to accurately hit the target, with an ordinary warhead is simply overkill, generally a nuclear warhead.

And the other parts have the engine, propellant, guidance device, protection device and a series of other things.

The focus of the first investigation is the warhead!

In the process of development, intercontinental missiles are divided into five generations, the first generation is mainly based on liquid fuel, the preparation time for launch is long, the refueling is easy to cause danger, and it is fixed on the launch frame. The accuracy is also very impressive, with a CEP within ten kilometers. The warheads are mainly large-yield nuclear bombs.

In the process of advancing technology, the second generation only improved the CEP, and the error was reduced to less than two kilometers. The third generation uses solid fuel and cluster multiple warheads, which greatly increases the lethality of cities, aircraft carriers, islands and other targets!

The fourth-generation intercontinental missile adopts the technology of split-guided multiple warheads, so that one intercontinental missile has the possibility of hitting multiple targets. The accuracy has been greatly improved, and the error has been reduced to a distance of 500 meters.

The fifth generation has embarked on the road of miniaturization and vehicle-mounted, and pursues anti-interception, survivability and penetration capabilities!

What Zhu Cheng has to do is to divide the lead multiple warheads, even in the nuclear warheads, there are many classifications, and the choices of the three different atomic bombs of the simple chain reaction atomic bomb, hydrogen bomb and neutron bomb are different.

Zhu Cheng has a lot to do, and the entire warhead is not just as simple as "explosives", in the fairing, there are also guidance devices, release devices, booster engines and other things, Zhu Cheng needs to complete them one by one, and then finally assemble them.

The first thing he did was "explosives", and the atomic bomb charge was divided into two pieces, each of which was less than the critical mass, so that there was no nuclear fission chain reaction in normal times.

When the detonating device ignites ordinary explosives, the two charges are pushed together, and the overall mass is greater than the critical mass, and under the bombardment of neutrons, a nuclear fission chain reaction is produced, and then a nuclear explosion occurs.

At present, the power of the atomic bomb can reach tens of thousands of tons to hundreds of thousands of tons. And the equivalent of one kilogram of plutonium-239 is 20,000 tons***.

He carefully charged, but he still didn't escape the fate of the explosion! Seeing that the situation was not good, he turned around and ran, and then with a bang, he was blown to pieces!

When he refreshed next to Trester again, he deeply realized how filthy this shadow-like intelligent creature was!

"How many more times have you refreshed and resurrected like this?" Zhu Cheng asked a little panting, just now between life and death, he seemed to have comprehended something, but he didn't remember anything.

He wanted to recall the scene "before death", but he didn't remember anything. On the contrary, he felt that it was very unpleasant.

"You chose it yourself, and I didn't let you choose it! You can quit at any time! There are special protective oblivion settings that make you forget everything before you die! Trester said with a calm smile, he was just a virtual image. What can Zhu Cheng do to him? And it is also his ability to make this young man, who has always been very calm, angry and ashamed.

"Okay, hopefully a few less refreshes."

It's all about the perfect upgrade! Zhu Cheng cheered himself up, and then set out again on the road to make a chain atomic warhead, and he wanted to make not one. There are few mistakes in this process, it is just a mushroom cloud, and then the ending is refreshed.

When I assemble a warhead, instantly! Space! Burst! Explode!

Zhu Cheng was completely annoyed, he stared at Terrest fiercely, the exam is for people to pass, this is embarrassing!

"Is it possible to pass this exam? If you make a slight mistake, you will explode directly, and you are sure that you are not playing people, is it really the content of the assessment? ”

And this angry and corrupt look naturally caused Trester to laugh.

"Of course it's possible! In fact, this process has great benefits for the understanding of Level 2 books, and if you pass the exam, it will be a strong help for you in the future! I advise you to try a few more times. Protecting the Forgotten Device allows you to forget the experience of death and you have nothing to lose. ”

Zhu Cheng gritted his teeth and walked in front of the chain reaction atomic bomb again, of course, what he wanted to do was not only the atomic bomb, the hydrogen bomb of thermonuclear reaction was the first choice for intercontinental missiles now!

Using a small atomic bomb as a detonation device, after the small atomic bomb is detonated, the neutron stream is released and an ultra-high temperature and ultra-high pressure environment is formed, creating conditions for nuclear fusion!

And the atomic bomb has also been instantly increased from tens of thousands of tons or hundreds of thousands of tons to millions and tens of millions of tons!

At the time, the world's largest hydrogen bomb, Ivan, had a yield of 58 million tons, erasing an island from the map, and the electromagnetic pulse wave caused a one-hour window of radio communication around the world. And the power of the explosion pushed the Eurasian plate southward by 9 millimeters.

What he did in his hands was a more terrible weapon than the original Great Ivan! At the beginning, because of the low accuracy, in order to be able to achieve strategic goals, high-yield nuclear bombs were rampant, and now! What Zhu Cheng wants to do is to be more accurate! (To be continued.) )
