At night, when there was no one in the laboratory, Zhang Yi did a sulfuric acid residue experiment for more than two hours.

Now the sulfuric acid slag experiment has been done for two days, and his plan is also going smoothly, and the experimental results of the sulfuric acid slag are also expected.

However, before that, Zhang Yi still selected some samples and sent them to the testing center, and used the instruments and equipment of the testing center to do some microscopic analysis, so that in his technical report, in addition to a bunch of experimental data, there are some more "official" analysis reports for technical support.

The next morning, Zhang Yi came to Professor Li's laboratory as usual.

Ye Bin and Ning Que are also doing experiments step by step, and the experimental results are also good, and the progress of the experiment is much faster with the plan.

Zhang Yi's main task is to guide, he does not participate in the experiment, the experimental results and data processing are completed by Professor Li's research group internally, Zhang Yi only needs to escort the experiment.

In a corner of the laboratory, Ning Que was preparing nano titanium dioxide, and when he saw Zhang Yi coming, his hands kept moving, and he said hello to Zhang Yi by the way, "Leader Zhang, I'm here to inspect the work again." ”

If you want to say who admires Zhang Yi the most in this laboratory, it must be Ning Que, Ning Que knows Zhang Yi well, in his mind, Zhang Yi is not necessarily better than him before entering the university, the reason why Zhang Yi can have the current ability is that he must be very hard and serious after entering the university, and has accumulated a lot of knowledge.

Ye Bin had never been in contact with Zhang Yi before, and he thought that Zhang Yi had been interested in scientific research since he was a child, and he had talent in this area, coupled with diligence and studiousness, it was possible to have the current level.

"I'll just take a look at what you're inspecting. Zhang Yi smiled dumbly, in fact, the relationship with Ning Que, he still wanted to maintain the same simple classmate relationship as before, but after the sunscreen, he could feel that Ning Que's attitude towards him had changed, which made him feel helpless, but the opportunity was in front of him and it was imperative, if he didn't seize the opportunity of this sunscreen, Zhang Yi would be very sorry in his heart.

"By the way, Zhang Yi, I have already contacted Xiaohu yesterday, if you have time, we will go to Tianyue Hotel for a meal tonight, I lost the last bet and haven't invited a treat." When he said this, Ning Que couldn't help but feel a little ashamed, but he was also willing to gamble and lose, and Zhang Yi also helped a lot in this sunscreen project, and he also learned a lot.

And to be able to participate in this project, his future can be said to be bright in the future, Professor Li has the intention to recruit him into the research group for graduate studies, these can be said to be brought by Zhang Yi, please have a meal to thank Zhang Yi is also light.

"Tianyue Hotel? That's good, but can the time be a little later?" Zhang Yi hesitated slightly, but still agreed, this is the bet agreement that the two of them agreed before, in fact, it doesn't matter if Ning Que invites Zhang Yi to eat or not, but if he refuses, it will hurt Ning Que's heart somewhat, after all, he has a lost gambling contract on his back and doesn't pay it back, and his heart is not a good feeling.

But thinking that he had to do the sulfuric acid slag experiment at night, Zhang Yi didn't have enough time, so it seemed that he could only advance the sulfuric acid slag experiment a little earlier, and then complete it as soon as possible, and then go to Tianyue Hotel.

Seeing that Zhang Yi agreed, Ning Que was also very happy, he was afraid that Zhang Yi would think that he was joking before and refused, so this favor would not be repaid, "It's okay, what about 7 o'clock in the afternoon? If you don't go at this time, you will starve to death." ”

"Okay, that's 7 o'clock. Zhang Yi knew that it was already late for dinner at this time, and he was embarrassed to ask others to follow him hungry.

Just as Zhang Yi and Ning Que were chatting while doing experiments, Lin Xiayu quietly walked over.

"Zhang Yi, you come with me. Lin Xiayu's expression was a little gloomy, and his tone of voice was a little cold.

Zhang Yi didn't know what the situation was for a while, looking at Lin Xiayu's appearance, I was afraid that there would be nothing good, but Zhang Yi had nothing to do with her, and he was not afraid that she would trouble herself, so he said lightly: "Can't you say it here?"

"Don't worry about it, just come with me, in short, it's for your own good. After Lin Xiayu finished speaking, he turned around and left, leaving Zhang Yi and Ning Que with bewildered faces.

Zhang Yi couldn't go if he didn't go like this, and he still wondered if he had offended this eldest lady during this time? Is this to settle accounts with himself?

With a puzzled face, Zhang Yi followed Lin Xiayu out of the laboratory. Ning Que looked at the spot and didn't dare to follow, Lin Xiayu was her senior sister, and her temper was well-known in the entire academy, he didn't dare to provoke her.

Lin Xiayu stopped at the end of the corridor outside the laboratory, this place was close to the safety staircase, and there were few people who usually came, and he was not afraid of being listened to by others when he talked here.

Zhang Yi also walked to Lin Xiayu in three steps and two steps.

Seeing Zhang Yi approaching, Lin Xiayu said with a solemn expression: "Zhang Yi, tell me honestly, did you steal your composite sunscreen technology?"

"What, are you kidding me?" Zhang Yi was taken aback by Lin Xiayu, shook his head and said, "Your joke is not funny at all. ”

Seeing that Zhang Yi was still stiff-mouthed, Lin Xiayu had a feeling of hatred in her heart, she came to Zhang Yi alone now, just because she was afraid that things would make a big deal and affect his future, how difficult it was to go to college, if he was punished or even expelled because of this matter, Zhang Yi would regret it for life.

She thought that as long as Zhang Yi admitted her mistake to her, she would go to Professor Li to talk about it and strive for Professor Li's forgiveness, then this matter would not make a big fuss, as long as it didn't spread, Zhang Yi would not be affected.

"What a joke, can you be serious, it may be too late for you to admit your mistakes earlier, otherwise you can't afford the consequences. Lin Xiayu's face was cloudy, and he was extremely disappointed in Zhang Yi in his heart.

When I first saw Zhang Yi at first sight, I thought Zhang Yi was bragging, and I didn't have a good impression of him, but since Zhang Yi made a composite sunscreen product, she finally changed her opinion of Zhang Yi.

Even if it is the technology stolen by Zhang Yi, but he can make the finished product very skillfully, which is much better than many people engaged in scientific research, so she is willing to help him, and now it seems that her kindness is all regarded as a donkey's liver and lungs.

Zhang Yi frowned, he didn't know where Lin Xiayu judged that his technology was stolen, this was purely slander, and he had to admit that he just didn't know what to say, inexplicable, and said a little depressed in his heart: "I don't know what you're talking about." ”

Hearing this, Lin Xiayu had completely given up on Zhang Yi, she had already given the opportunity, Zhang Yi didn't cherish it, for the benefit of the research group, she could only go through the procedure, Lin Xiayu said disheartenedly: "You can do it yourself." ”

After speaking, he turned around and left, leaving Zhang Yi stunned in place.

"Inexplicable. Zhang Yi didn't know what Lin Xiayu's nerves were, and suddenly said that his technology was stolen, which made him feel a little angry.
