"Half of the answer is correct! Don't forget it! Let's move on to the next session!" Trieste said with widened eyes.

Zhu Cheng counted with his fingers for a long time before he realized that the last question should have given him 4 points!And under the principle of half right and half wrong, this question should be worth 8 points!
His guess was not wrong. This was a question that could be answered by leaps and bounds. Although Zhu Cheng didn't have a perfect answer, he had to get the points he deserved.

"The problem of first-level books is already difficult for you. Your grasp of first-level books is very strong. You have created a record. This record will be recorded in the library system and accept the challenges of all intelligent creatures! You You know, all intelligent creatures will challenge you when they take the first student upgrade exam."

Trieste's words couldn't hide the vicissitudes of life, because Zhu Cheng had set a record, and his mastery of first-level books was unprecedented.As for whether there are any visitors, who can say clearly?
"How did you do it? You know, I can understand why you can master, understand and flexibly use all subjects if you specialize in one subject and get such good grades?"

Trieste is too curious. Today, when science is becoming more and more difficult to understand, it is very difficult to achieve specialization in all disciplines and have considerable achievements in various fields.

"Is it difficult?" Zhu Cheng was still somewhat dissatisfied with the difficulty of the additional questions. In his opinion, the questions of these questions still did not meet the specifications.

"It's not hormones that open the door to human enhancement. It can only be viruses." Trieste said suddenly and mysteriously, then turned around and started typing on a platform that suddenly appeared.He pointed out where Zhu Cheng was wrong.

Zhu Cheng savored this sentence carefully, and benefited a lot. The essence of hormones is protein. DNA transmits genetic code to RNA, and RNA is transcribed and modified into protein. This is telling him that genes are the door to strengthening.

The point of this sentence will save him a lot of trials and related calculations!It is conceivable to improve the progress of human enhancement!Trieste knows the direction of the future, and what biology needs is the direction!

Before physics, there were Hooke and Newton, and later there were Maxwell and Einstein. They guided the direction of physical research, but in biology, only one pea experiment is widely known to the world.Biology lacks a giant to point the way forward.

When Zhu Cheng was in a daze, the surrounding scene began to change, from an illusory and empty space to concrete and realistic.What gradually emerged was the appearance of a super-large laboratory.

Want to run a mock experiment?

Zhu Cheng sighed. He also thought about building a simulation laboratory in the "Origin" game, but without quantum computers, the amount of calculation provided by distributed computing can only be used by biological special computers.

There is no original calculation amount at all!The original computing power comes entirely from supercomputers.That amount of calculation is already too much to support the "Origin" world, let alone Zhu Cheng's simulation experiment.

"Congratulations to student Zhu Cheng, who has won the title of 'Doing Questions Like Sweeping the Floor'. With this title, you can enjoy a first-level discount when borrowing books!"

"Congratulations to student Zhu Cheng, who broke the record in the entire library! This will also be recorded! For the challenge of upgrading intelligent creatures in the entire area! Reward student Zhu Cheng with 3000 contribution points!"

3000 contribution points, no other rewards?Zhu Cheng always felt that the record in the whole district was broken, and there were really few rewards.

"Because my advice to you should have been 10000 contribution points, but it was downgraded to 5000 points. Because of my private rewards for you, the rewards have been reduced by [-] points again. Of course, this does not mean that my private rewards are worth this Contribute points. Let’s talk about it after you get it.”

Trieste added a sentence to explain the reason, and Zhu Cheng still doesn't quite understand the usefulness of this contribution point, just exchange it for items in the exhibition room?That's a waste of contribution points!
"Contribution points are very useful. You will understand these contents after upgrading! Alright, let's prepare for the next exam content! The second test is about hands-on ability. It is also 100 operation experiments and 40 additional experiments. The challenge! The test is your hands-on ability! I hope you will pass the test well!"

Trieste's attitude has changed from being curious about the reference of the K0 civilization to a solemn and a little bit of respect!
This Zhu Cheng has full potential, which is very good for him.He directly said that apart from the additional questions, he just told Zhu Cheng his expectations.Although it was very vague, he believed that Zhu Cheng could hear and understand the meaning.

"I understand."

Zhu Cheng began to operate. The experiments here are all the experiments he had done on the earth. After all, the first-level books are only a section beyond the content of the earth. After he has the gold-absorbing tool of Cree, the experiment has never stopped. .His investment in private laboratories far exceeds the investment in biological laboratories.

He came up to do the hydrothermal method to grow nonlinear optical large crystals, named KOOF.

Potassium fluoroboroboryryllate, or KBBF, is the crystal with the shortest phase-matched frequency doubling wavelength known so far. The problem faced by KBBF grown by the molten salt method is that the thickness of the large crystal produced in the chapter is relatively thin, with a thickness of about 1mm. , this thickness cannot be cut into frequency doubling devices in the phase matching direction.This makes KBBF less practical for optical frequency doubling.

The development of hydrothermal method makes this disadvantage less obvious.At that time, during the use of KBBF, there is still a huge problem, which is about beryllium. This element is highly toxic, and it is easy to cause serious harm to scientific researchers in actual operation.

And KOOF is looking for an element to replace beryllium, so that the toxicity of beryllium will disappear, and there will be new possibilities for optical frequency doubling!go further!

Zhu Cheng's goal is to obtain a super-powerful laser to emit terahertz. This experiment was done by Zhu Chengxin with his own hands. The complete experimental procedures and meticulous experimental attitude also made Trestle nod. This is the attitude that a researcher should have. Well!
Zhu Cheng carefully weighed the mixture, mixed it evenly, put it into a platinum crucible, then put it into a heating furnace and heated it to 750°C, and then cooled it down to room temperature after keeping the temperature constant for 1 hour.Press the above primary sintered materials into pieces with an oil press and put them into a platinum crucible, then put them into a furnace and heat them to 800°C for sintering, keep the temperature down to room temperature after 1 hour.

Turn on the X-ray powder diffractometer and observe the diffraction pattern to determine the purity of the formed compound. After confirming that the purity is high, weigh 5g of raw materials and put them into an autoclave.Then an aqueous solution was added.There is a baffle in the kettle to separate the kettle body into a lower dissolution zone and an upper growth zone.Suspend the seed crystal within the growth zone.The autoclave was closed tightly and placed in a furnace with two-zone heating for a 20-day growth cycle.

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

Zhu Cheng suddenly discovered that this exam is still a rather terrifying physical labor. There are still 99 experiments in front of him. The planet appeared in front of him, and he was preparing for the third exam.

In the upgrade exam for library students, the third level is temporarily set by the invigilator. The difficulty depends entirely on the invigilator's mood. The official deliberately increased the difficulty of the questions, resulting in poor scores and affecting the overall evaluation!

In addition to the possibility of offending the invigilator and increasing the difficulty of the question, there is another possibility that the invigilator thinks that some intelligent creatures have enough ability, and when the weak test is an insult to the examiner, the difficulty will also increase!

Obviously, Trieste's smirking expression while setting the topic shows the difficulty of the third level.However, Zhu Cheng, who was devoted to the experiment, did not see this smile. His experiment went smoothly, just like when he was taking the exam, he finished all the experiments smoothly.

"Is it finished?" Trieste asked, he didn't ask knowingly, but he was excited about the third topic set!

"Congratulations to student Zhu Cheng, who has won the title of 'Doing experiments is as easy as pie'. This title can enjoy a first-level discount when borrowing books! It is superimposed with the first title."

"Congratulations to student Zhu Cheng, who broke the record of the library's experimental score! This will also be recorded! For the challenge of upgrading intelligent creatures in the entire district! Reward Zhu Cheng with 10000 contribution points!"

There is no discount for this contribution point, and he has completely received all the rewards. After doing some calculations, Zhu Cheng got the second-level preferential borrowing permission and 1.3 contribution points.

"Look, the rewards are all brushed out. These experiments are very simple. There is no challenge at all."

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

For high school students, the college entrance examination 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.

"Then are you ready to challenge the third level? There is only one question this time. But you understand the difficulty." Trieste had a smirk on his face. For the third level exam, although there are no books beyond the first level Restricted, but it involves more advanced book knowledge.His clever setup circumvented the library's rules, and he was proud of his setup.

Zhu Cheng was a little curious. During this trip to another planet, the questions in the two tests were a bit simple. After taking a look at the third test paper, he was dumbfounded.

"Is it really okay for you to play like this?"
