Biquge lightnovelpub.net, the latest update of the blackest male master always wants to set my latest chapter!

I just hope that it can end quickly and go home.

The chemistry teacher came to Su Yan and saw that Su Yan didn't finish the test paper, and there was a look of surprise on his face.

No, it should be surprising, and one more thing ... happy? ?

Although as a teacher, this seems very inauthentic.

However, since their students started to do the difficult chemistry competition, they have never missed it.

It's too frustrating to make this teacher useless.

Gu Zheng quickly finished the check.

Full marks.

Yuan Xinlin and Zhao Sen also had good results, and the last big question was solved more than half.

The chemistry teacher stood in front of Su Yan, holding her papers, frowning and looking serious.

"Although the type of this question is a new type of question that has just been added this year, it is not too clueless. I told you a similar question yesterday. I just changed a few numbers. It should be done than a gourd painting Now. "

When the chemistry teacher was talking, he picked up Gu's test papers, neatly written, and the equations were written very well.

"In accordance with this momentum, there is no problem in entering the top ten nationwide."

There was a happy smile on Gu Yan's face.

"Thank you, teacher."

Then, the chemistry teacher mentioned Yuan Xinlin and Zhao Sen one or two.

Seeing that the two men opened their mouths and lowered their heads to solve the problem, their attention turned back to Su Yan's body.

You know, he attaches great importance to Su Yan.

Su Yan is a treasure he pressed.

Whether or not the first trophy in the national chemistry competition can enter Didu High School depends on her! !!

He thought about it for a while, and felt that he still couldn't hit Su Yan too much. In case of excessive sadness, he had not adjusted his mentality well, and it was over until the real exam day.

The so-called severest bald teacher in Didu High School, sitting next to Su Yan, showed a rare touch of beauty.

"Su Yan, this question is not as difficult as you think. You just need to understand that the yellow substance phosphite in the question is ..."

Su Yan had a lengthy discussion with her chemistry teacher. She looked at the increasingly gloomy weather outside, interrupted softly.

"Teacher, there is no solution to this problem."

As soon as she spoke, the patient teacher gave a meal.

The chemistry teacher hasn't spoken yet, Gu Yan has already taken the lead

"It can't be impossible. The standard answer is here, and I have already solved it."

The words were still gentle, but firm.

Although Gu Yan looks weak, he is actually a very self-conscious person.

It was a long time since the first fight, and suddenly Su Yan appeared, and it took everyone's attention without any effort.

At first I was unwilling.

So she worked hard to solve the problem in order to one day surpass Su Yan.

And it turned out that her efforts were effective.

Today, she has successfully surpassed Su Yan.

But this Su Yan now said such a thing, was it because she was exceeded?

Gu Yi had a touch of joy in his heart.

Should let her taste this defeated taste.

Su Yan looked down and did not argue.

Just pick up the pen next to it and draw a line on the sentence.

"It shouldn't be ammonia, but carbon dioxide. Otherwise the formula would never conserve mass."

The question itself is wrong. How can it be solved?

The exam paper that she drew a line was taken by the teacher.

Study it carefully.

Ten minutes passed, and the weather outside was more gloomy, as if it would rain in the next second.
