Zhang Wenkai, who hadn't moved for a long time, suddenly raised a hand in front of the sun and put it in front of him, as if he was looking at something.

In Zhang Wenkai's palm, a transparent test tube could be seen, but soon after, suddenly there was a slight change in the test tube, only to see the color in the test tube, first red, then turned yellow and finally returned to red, although it was not pure red, but it was crystal clear.

There was not a trace of fluctuation on his face, and a pair of eyes were still staring at the test tube, only listening to the continuous grunting of the test tube in his hand! Grunt! The bubbling sound and his still eyes were in stark contrast.

Time passed minute by minute, and the liquid in the glass bottle continued to show its extraordinary chemical formula, without the slightest intention of stopping, but Zhang Wenkai couldn't bear it anymore, his raised hand was already trembling slightly, at first it was just a hand, but as time passed, the wrists, elbows, the whole arm, and even the whole body gradually trembled.

Zhang Wenkai held the glass bottle closer to the sun, his arm still trembling, but he didn't pay attention.

His eyes stared at the test tube in the sun, his face was a little red, and the skin on his exposed forehead and neck also had some small beads of sweat, as if he had done some kind of physical exercise, and his body was damp up and down.

After a while, the liquid in the test tube reacted violently again in front of Zhang Wenkai's eyes, only to see bubbles of different sizes quickly emerging from it, and finally the liquid in the test tube calmed down, without a trace of reaction, and regained its red color.

After the reaction in the test tube disappeared, Zhang Wenkai immediately sat on the chair closest to him as if he had lost the support of his bones, looking very tired, as if he had just experienced a marathon.

"This nutrient solution is really difficult to configure! After I got the formula, I studied it for nearly half a day, and I still have some clues, and there are a lot of problems when configuring, but now it should be successful! Zhang Wenkai looked at the small bottle on the table and muttered to himself.

It turned out that Xiao Na gave Zhang Wenkai several formulas of plant nutrient solution, and since Xiao Na talked about the function of the nutrient solution, he has become very interested in this nutrient solution.

But it's a pity that so far, Zhang Wenkai, with his level of no understanding of bioengineering, and he doesn't even know how to use all kinds of practical equipment, actually prepared a nutrient solution for plants, which can not make him happy.

Xiao Na said that the nutrient solution accelerates rooting, catalyzes leaf growth, promotes development, and increases nutrients, and Zhang Wenkai blends the simplest one, which is to increase nutrients.

This is not to blame Zhang Wenkai, the main reason is that this nutrient solution has exceeded the scope of his cognition, even if he reads a lot of books, he still knows very little about this knowledge, and naturally he can't mix such a complex thing.

In desperation, Zhang Wenkai took out the tenacity to study alien codes, not afraid of hardship or tiredness, bought various books on botany and floriculture, and began to study the true meaning of it day and night, and repeatedly studied every sentence in the book dozens of times before he achieved today's results.

Even if he hadn't learned this knowledge before, he knew that once this powerful nutrient solution was mixed wrong, the liquid that was mixed out would not be a nutrient solution, but a poison.

After several weeks of research, Zhang Wenkai finally understood the various steps of the formula and the size of the drug use, so he started to make the nutrient solution above.

This actual operation has brought a lot of blows to Zhang Wenkai, and it is no wonder that there are very few talents in this area in China.

He originally thought that with that little bit of technology and cognitive process on electronics, it would not be too difficult to learn bioengineering-related knowledge, but who knew that he suddenly became stupid, as if there was a problem with IQ, he knew the steps, but as soon as he got to his hands, all kinds of mistakes were frequent, either the wrong addition of the test solution, or the wrong use of the equipment was contaminated, and it seemed that the whole person felt wrong.

Zhang Wenkai was also a little helpless about this, if it was a problem of IQ, he wouldn't say anything, but it was a problem of hand handicap, and this kind of hand handicap could only be practiced slowly.

Although he can't master these complex knowledge, as long as he is given enough time, he will master it sooner or later, this is the conclusion Zhang Wenkai made for himself.

After Zhang Wenkai's long-term practice, he finally managed to make a slight difference in the use of various instruments, but he was not confident that he could prepare several other nutrient solutions.

Even this kind of frustration has affected the people around him, and Zhou Yuya knows that he is not in a very good mood for a while, and keeps comforting himself.

The function of this nutrient solution that increases nutrients did not disappoint Zhang Wenkai, and even exceeded his expectations.

Don't open it is just a simple red liquid, but its function is not to be underestimated, as long as it is not an infected plant, as long as you use it, it will instantly become vibrant.

Even some sick plants have used it, and their growth has improved, and the branches and leaves have been pulled out.

Seeing such a powerful nutrient solution, Zhang Wenkai was surprised, and hurriedly conducted a detailed test on it, and the results of the test were unexpected, it has obvious effects on any plant.

After thoroughly understanding the function of nutrition, Zhang Wenkai finally understood why Xiao Na said that he could help him transform the earth, and it was more than wrong to transform the earth with the technology that Xiao Na gave him.

Imagine that as long as Cortana provides ready-made technology or formulas, such advanced things can be made, if Cortana gives more advanced technology, and creates something that is leading the world, then it will not be invincible in the world!

Thinking of this, even Zhang Wenkai, who has experienced so much, is a little fluttering.

Reaching out and touching the box that carried Cortana, he made up his mind that even if he died, he would not let others know Cortana's secret.

Cortana has no self-nature, and once the bad guys get it, the only result is to destroy the miè world.

His family and friends all live in this world, and he definitely doesn't see the world being ruined.

Zhang Wenkai rubbed his head, he was thinking too far, it was useless at all, it was better to put his energy into the work in front of him! Thinking of this, he began to mix the nutrient solution again. (To be continued.) )
