"Half the answer is right! Don't forget it! Let's move on to the next step! Trest said with a glare. Pen, fun, pavilion www. biquge。 info

Zhu Cheng counted his fingers for a long time before he understood that the last question should have added 4 points to him! And under the principle of half right and half wrong to half, this question should be worth 8 points!

His guess was not wrong, this was a question that was answered by leapfrogging, although Zhu Cheng did not have a perfect answer, but he should get the score he got, and he must get it.

"The problem of the first level of books is already difficult for you, your mastery of the first level of books is very strong, you have created a record that will be recorded in the library system, and accept the challenge of all intelligent beings! You must know that all sapient beings will challenge you when they take the first Cadet Advancement Exam. ”

What Trest's words can't hide is the vicissitudes of life, because Zhu Cheng has created a record, and his mastery of first-class books is unprecedented. As for whether there is anyone who comes, who can say clearly?

"How did you do that? You know, if you specialize in one subject and get good grades to this extent, I can understand why you can master, understand and apply all of them. ”

Trest is too curious, and in today's increasingly incomprehensible science, it is difficult to achieve specialization in all disciplines and have quite high achievements in various fields.

"Is it hard?" Zhu Cheng is still a little dissatisfied with the difficulty of the additional questions, and the problems of these questions, in his opinion, are still a little out of standard.

"It's not hormones that open the door to human strengthening. It can only be a virus. Trest said suddenly and mysteriously, turning around and typing on a platform that suddenly appeared. He pointed out where Zhu Cheng was wrong.

Zhu Cheng carefully tasted this sentence and benefited a lot, the essence of hormones is protein, DNA transmits the genetic code to RNA, and RNA transcription and modification into protein, which is telling him that genes are the door to strengthening.

The mention of this sentence will save him a lot of tests and related calculations! The improvement of the human enhancement progress can be imagined! Trest knows the direction of the future, and biology needs direction!

Before physics, there were Hooke and Newton, and then Maxwell and Einstein, who guided the scientific research of physics, and biology has only one pea experiment. Biology lacks a giant to point the way forward.

When Zhu Cheng was in a daze, the surrounding scene began to change, from an ethereal and empty space to become concrete and realistic. Slowly, the appearance of an oversized laboratory emerged.

Do you want to run a simulation?

Zhu Cheng sighed, he also thought about doing a simulation laboratory in the "Origin" game, but there is no quantum computer, even the amount of computation provided by distributed computing can only be used by biological special computers.

There is no original amount of computation at all! The original computing power comes entirely from supercomputers. That amount of computation to support the "origin" world is already stretched, and I am even more afraid of Zhu Cheng's simulation experiment.

"Congratulations to student Zhu Cheng, who won the title of 'doing questions like sweeping the floor', this title enjoys a first-class discount when borrowing books!"

"Congratulations to student Zhu Cheng for breaking the record of the whole library! This will also be on the record! For the whole district to upgrade the smart creatures to challenge! Reward Zhu Cheng students with 3,000 contribution points! ”

3000 contribution points, no other rewards? Zhu Cheng always felt that this district-wide record was broken, and the rewards were a bit less.

"Because of my guidance to you, which was supposed to be 10,000 contribution points, was downgraded to 5,000 points, because of my personal reward for you, the reward was lowered by two thousand points again. Of course, this is not to say that my private reward is worth this contribution point. Let's talk about it after you get it. ”

Trester added a sentence to explain this reason, and Zhu Cheng still doesn't quite understand the use of this contribution point, simply exchange the items in the exhibition room? That's a waste of contribution points!

"Contribution points are very useful, and you will naturally understand these contents after leveling up! Okay, let's get ready for the next exam! The second level is a test of hands-on ability, which is also a challenge of 100 operation experiments and 40 additional experiments! It's all about your hands-on ability! I hope you do well for the exam! ”

Trest's attitude has changed from the curiosity of the reference person looking at the K0 civilization to solemnity and a little respect!

This Zhu Cheng is full of potential, which is very good for him. He directly said that in addition to the additional questions, he told Zhu Cheng his expectations. Although it was very vague, he believed that Zhu Cheng could understand the meaning.

"I see."

Zhu Cheng began to operate, the experiments here are all the experiments he has done on the earth, after all, the first-class book is only a small section of the content of the earth, and he has never stopped experimenting after he has the gold-absorbing weapon of Cree. His investment in private laboratories has also far exceeded that in biological laboratories.

He came up to do the hydrothermal method of growing large nonlinear optical crystals, named koof.

Potassium fluoroboramylium berylliate, that is, KBBF, is currently known, the phase matching of the shortest frequency doubling wavelength of the crystal, the problem faced by the molten salt growth of KBBF, the thickness of the large crystal is thinner, the thickness is about 1mm, this thickness can not be cut into a frequency doubling device according to the phase matching direction. This makes the practical use of KBBF in optical frequency multiplication not high.

The growth of the hydrothermal method makes this drawback less obvious. At that time, there is still a huge problem in the use of KBBF, which is about beryllium, this element is highly toxic, which can easily cause serious harm to scientific researchers in actual operation.

And koof is to find an element to replace beryllium, so that the poison of beryllium disappears, so that the optical frequency doubling has new possibilities! Go further!

Zhu Cheng's purpose is to get a super laser to hit terahertz, this experiment Zhu Chengcheng pinched it by hand, the complete experimental procedures, and the meticulous experimental attitude also made Trester nod, this is the attitude that a researcher should have!

Zhu Cheng carefully weighed the mixture, mixed evenly, put it into a platinum crucible, and then put it in a heating furnace to heat it to 750C, and then dropped to room temperature after 1 hour of constant temperature. The above primary sintering material is pressed into pieces by hydraulic press and loaded into a platinum crucible, and then put into the furnace to heat to 800C for sintering, and the constant temperature is reduced to room temperature after 1h.

Turn on the X-ray powder diffractometer, observe the diffraction pattern to determine the purity of the formed compound, and after determining the high purity, weigh 5g of raw materials and load them into an autoclave. An aqueous solution was then added. There is a baffle in the kettle to separate the kettle body into the lower dissolution zone and the upper growth zone. Suspend the seed crystals in the growing zone. The autoclave is closed and placed in a furnace with two-zone heating, and the growth cycle is 20 days.

Zhu Cheng naturally couldn't wait for this time, he just needed to complete the experimental steps. And he has as many as 100 such strength tests, including the configuration of the new brain solution.

Zhu Cheng suddenly found that this exam was still a rather terrifying physical work, there were 99 experiments in front of him, he was concentrating on the experiment, and Treist couldn't be more satisfied except for nodding, he opened a light screen again, a planet appeared in front of him, and he was preparing for the third exam.

In the library student upgrade exam, the third level is the invigilator temporary questions, this difficulty depends on the mood of the invigilator, this is also the exam precautions, repeatedly reminded of the content, do not contradict the invigilator, because this consequence is to let the invigilator deliberately increase the difficulty of the question, resulting in poor scores, affecting the comprehensive evaluation!

In addition to the possibility that offending the invigilator may increase the difficulty of the question, there is also the possibility that the invigilator thinks that some intelligent beings are capable enough, and the weak test is an insult to the reference, the difficulty will also increase!

Obviously, Treist's smirking expression while setting the question illustrates the difficulty of the third level. And Zhu Cheng, who was dedicated to doing experiments, didn't see this smile, his experiments were very smooth, just like when he was examine, he completed all the experiments smoothly.

"Is it done?" Trester asked, not knowingly, but excited about the third question set!

"Congratulations to student Zhu Cheng for winning the title of 'Doing Experiments as Easy as Palm', this title enjoys a first-class discount when borrowing books! Stacks with the first title. ”

"Congratulations to student Zhu Cheng for breaking the record of the experimental score in the whole library! This will also be on the record! For the whole district to upgrade the smart creatures to challenge! Reward Zhu Cheng students with 10,000 contribution points! ”

There is no discount for this contribution point, and he has completely got all the rewards, Zhu Cheng calculated it, and got the second-level preferential borrowing privilege, and 13,000 contribution points.

"You see, the rewards are all brushed out. These experiments are simple. It's not challenging at all. ”

Until this time, Zhu Cheng had more confidence in passing this upgrade exam perfectly! Relatively speaking, this kind of super-civilized exam is not as good as the mathematics of the domestic college entrance examination.

For high school students, gaokao math is a nightmare. For Zhu Cheng, this upgrade exam is more about traveling, seeing a deserted planet and a civilization far beyond the earth.

"Are you ready to take on the third level? This time there is only one question. It's just that you know the difficulty. Trest smiled evilly, for the third level of the exam, although it did not exceed the limit of first-level books, it involved more advanced book knowledge. He cleverly bypassed the rules of the library, and he was proud of his setup.

Zhu Cheng was a little curious, on this trip to another planet, the questions of the two levels were a bit simple, and when he took the third test paper, he began to be dumbfounded.

"Is it really okay for you to play like this?" (To be continued.) )
