The assessment of the third level was carried out vigorously, with roars and mushroom clouds constantly appearing, although Zhu Cheng insisted on it for longer and longer, but the explosion was still happening, which meant that he did not succeed once. Pen, fun, and www.biquge.info

"The 1387th experiment, from the K0 civilization, I suggest you give up, in an unfamiliar field, it is difficult to complete a subject that has not been completed before." Trest began to mumble again, this problem is so difficult, Zhu Cheng wants to finish, it is too difficult.

Zhu Cheng really wanted to find a sofa to lean on and use an authentic way of sitting, to relieve his nervous nerves, his mood was really a little irritable.

"Weapons are always the most sophisticated products of a civilization, and many weapons are a combination of thousands of achievements, with devastating power, and the content of science and technology is unprecedented! And whoever has more than one era of technology, then he has the ability to bully others. ”

"Don't be arrogant and rash, and if you don't plan to give up, try to complete this experiment. When this is done, you will know the purpose of my investigation. ”

Zhu Cheng was dumbfounded, is the exam still purposeful? And not in deliberately embarrassing him?

"The purpose of the expedition? What purpose? ”

Trester didn't answer the question, he gestured to the restored production area and said, "Give up or continue." ”

"Go ahead." After Zhu Cheng finished speaking, he didn't do it, and the structure of the nuclear bomb is also different, from the gun-type nuclear bomb at the beginning to the current implosion nuclear warhead.

The gun nuclear warhead is long and narrow, and it will be able to propel subcritical fissile material into another spherical block of subcritical fissile material along one tube, that is, into the "barrel." The gun structure is relatively simple, and the design is relatively confident. That's what he started thinking about.

It is clear that this primitive method to the extreme has a very low utilization rate for nuclear charges. He already knows the mistake of this structure, so let's change the way of thinking!

Implosion! The atomic bomb made a spherical device of ordinary high explosives and placed a small ball of nuclear charge smaller than a critical volume in the ball of explosives. The explosives detonate at the same time, quickly compressing the pellets of the nuclear charge and reaching a supercritical volume, causing a nuclear explosion.

The structure of the implosion atomic bomb is complex, but the nuclear charge utilization rate is high. The utilization rate of nuclear charges was increased to about 80%, which obtained great destructive power.

The reason why Zhu Cheng did not choose this method at the beginning was that he knew very little about this area, and only a little bit of the content in the first-level book involved nuclear issues.

With only a little bit of content, it can be imagined how difficult it is for Zhu Cheng to complete this repeated experiment.

The roar started again, and Zhu Cheng couldn't remember how many times he had been refreshed, but he knew that his progress was advancing little by little!

A smile appeared on his face again, he was not afraid of mistakes, the most feared thing was not knowing where the mistakes were, and it was clear that the implosion-like structure was the right direction!

However, the scientific research work of biotechnology is often lacking in the general direction! No giant of biology tells all biologists where the road leads.

That's where it's hardest! You can only rely on countless repeated experiments, looking for a needle in a haystack to find the ethereal results, this difficulty can be imagined.

He threw this idea out of his mind and began to concentrate on the experiment, and after completing the nuclear warhead of the warhead, Zhu Cheng breathed a long sigh of relief, neither the fairing, nor the guidance device nor the release device would explode. He doesn't have to face the possibility of a refresh.

"Proctor, can I archive it? It's not easy to make this nuclear bomb! If it fails to assemble, will it have to be rubbed all over again? Zhu Cheng asked Terrest, in fact, this is the invigilator who has reduced the difficulty, Zhu Cheng knows his own family affairs, and the accuracy of military products is required to be at least one-seventieth of a hair.

The error is not more than one μ is the requirement of the military industry!

But he rubbed this nuclear bomb, it was just a false appearance, and when he finished it, Trest made corrections! He could see it. He just rubbed the rough steps out. It's not something to be proud of.

"Good, it can be archived." Trester let go, the experiments that had already been completed, the topics that had been completed, and then let him repeat the things he repeated, it was completely pointless.

"Thank you."

……

How long has this experiment been underway? Zhu Cheng is not clear about this question, and for Trest, who has lived for tens of thousands of years, time is the easiest to ignore as a normal state of life.

Zhu Cheng closed the fairing, this is his completed nuclear warhead. When the rocket lifts off, it will send its nuclear warhead into space, and then the warhead will re-enter the atmosphere, break through the black barrier, and complete the orbit correction under the action of the final booster engine.

The release device releases all the nuclear warheads and flies towards various targets!

"Boom! The world is destroyed! Zhu Cheng waved his hands exaggeratedly, he was very excited, this experiment was very difficult, whether it was refreshing or moving, there were a lot of thoughts, and he was naturally very happy to succeed.

"Imagine a wartime intercontinental missile with such a warhead flying all over the world, a mushroom cloud rising around the world, and an electromagnetic pulse leaving the entire planet's radio window in the window. Lives have been destroyed and countless people have been displaced. Families are ruined. This is war! Terrest's voice was a little embarrassed, he had seen countless civilizations rise and fall, and the most common reason was war.

Technology is constantly advancing, and weapons are becoming more and more terrifying! There is even the possibility of a large-scale nuclear leveling of the world! Zhu Cheng naturally understands this truth.

"No one wants war! But at no time should we be afraid of war! For Trest, war fanatics or capitulationists were not on his radar. He didn't have a position at all, he was just mentioning points.

"You mean to keep the scope of war within the destruction of civilization?" Zhu Cheng asked a question and fell into deep thought.

Trest shook two times in the air and said, "No, I mean, if someone doesn't accept it, just kill him!" Don't be afraid of fighting, only with competition can there be motivation to move forward. ”

"Let's start grading!" Zhu Cheng couldn't think about the answer to this question, as Tretus said, everything in the world is changing randomly, where did he know what would happen in the future.

"According to the scoring criteria of the Tellites administrator, Zhu Cheng received an A-grade evaluation in this trial, and this evaluation ranked 1380th in the assessment of Ettes, please keep up the good work."

And so it was! Zhu Cheng knew that he was not an avid war enthusiast, and it was already a very difficult thing to be able to successfully complete the experiment, and he could not expect to refresh this rule again.

Of course, Zhu Cheng didn't know the meaning of this A-level evaluation at all, and he didn't quite understand the significance of this 1380 for the whole library.

"Congratulations to student Zhu Cheng for completing three rounds of library upgrade assessment. Library upgrades are underway, please ...... later" He saw the familiar progress bar again, it had appeared once when he opened the exhibition room, and now the progress bar was slowly rising.

He has already opened the exhibition room in advance, but he is still looking forward to this upgrade, because it will be the opening of the borrowing rights of secondary books! He had already thought of a complete set of reading plans, just waiting for the upgrade to end!

"Zhu Cheng, congratulations on completing the third level of the assessment, I will also keep my promise, and I will honor the reward I promised to you when you get out of the exam warehouse."

"It's time to go offline." Trester gave Zhu Cheng an eviction order, and after the exam, he didn't hand in the papers and left, but he would be picked up by the invigilator! He didn't even notice that the name in his mouth had changed from a reference from the K0 civilization to a name. It's a subconscious sign of approval.

"Okay." Zhu Cheng searched for a long time, but did not find the exit button, silently quit, and then fell into a trance.

In the virtual space at this time, Trest uploaded the results of this exam to the library system and sent a broadcast to the whole district, causing the whole universe to boil. Countless wills converge in the air.

"What a pervert out there! the hens! The owner of the double title? It's good to give me one! ”

"The key is the 13,000 contribution points! How many things can be exchanged for this! How many of my academic problems can be solved by this! ”

"He got a Trest A-level evaluation, you must know that the A-level evaluation of Trestal is much more useful than those two titles!"

"I had an A-level evaluation at the beginning, and now it's not wandering around, but the head of a district......

……

The image of Zhu Cheng's exam is stored in the library system, and naturally Trest is not afraid of anyone to review it, this process is in line with the regulations of the library management system, and he has a clear conscience for the A-level evaluation!

Trest's A-grade rating is in the library system and has an excellent reputation! This stems from his tricky gaze and precise estimates!

Zhu Cheng squeezed his eyes, woke up from the exam warehouse, the door opened, and he walked out of the door step by step.

It was this withered world again, and Tianluo Xing, which did not have any life matter, appeared in front of him again.

The star's glow is still dim. And the brightness and temperature of the entire surface are like the sunset on a winter day.

It was a tragic contrast, with the grandeur of the massive buildings on one side and the lifeless apocalyptic scene on the other, which shook him deeply.

"Treist, how did Tianluo Star come to be?" He asked, this is good for the future development of the planet.

"The building under your feet is called the Mother Nest, and when the planet's resources were exhausted, the Tianluo people did not choose to leave their home planet, but used the Mother Nest to survive. It is clear that they failed. ”

Terrest's voice sounded in Zhu Cheng's ears. Zhu Cheng really can't say anything about this kind of civilization that plays himself to death, on the contrary, he cares more about his rewards.

"What is the reward from the librarian? Hope you don't let me down! Naturally, he didn't forget. (To be continued.) )
