Of course, these are not the so-called key points, but the two of them discussed some things about Wang Yan, which made Meng Ke feel that there was a lot of article in it.

He was still groggy, but now he immediately has the energy to listen to it, which is much more interesting than the teacher reciting the scriptures on the blackboard.

"Do you know, the representative of the English class has a boyfriend in the last few days, it seems to be Xu Li."

"No, he's not as handsome as me, how can he be with such a beautiful girl?"

The conversation between them all entered Meng Ke's ears word for word, and he was really in no mood to continue sleeping. You must know that Wang Yan is his only spiritual pillar in this class, just like a goddess. Now that he was robbed by Xu Ming's guy, he naturally wrote 10,000 dissatisfaction in his heart, and he was too jealous.

Even when he was running exercises, he was thinking about this question, it is likely that someone who used to be your classmate will now become a rival in love. Because of love, these will become inevitable. If he knew about the magic star spell witch giving Wang Yan's doll, then it would also become Meng Ke's enemy. A smile appeared on the corner of his mouth, it was time to compete with Xu Li, either he would die or I would die.

In anxious waiting, Meng Ke finally ushered in an opportunity. In the afternoon chemistry laboratory class, the students were refreshed, as if they had changed their tired faces.

For operating instruments or something, although there are specific steps to limit, relatively speaking, it is still quite troublesome, but this is better than a boring class, a bunch of equations and operations at a glance, so that you have a headache for a long time and can't solve the correct answer, can it not be uncomfortable.

Xu Li took Wang Yan's little hand in front of everyone, and coincidentally, the two of them were divided into a group.

Now Meng Ke has indeed seen it, he is even about to die, such a good cabbage, but it was arched by a pig. A beautiful woman with a scumbag, I believe that it won't be long before Wang Yan will take the initiative to break up with him.

The angry Meng Ke's teeth itched, and he slapped the experimental table hard, almost breaking a bottle of H2SO4. Of course, he didn't know what kind of chemical substance this was, and after asking Han Qing, he realized that it was sulfuric acid, a model of strong acid. He had also read about aqua regia in textbooks, which was made by mixing hydrochloric acid with nitric acid in different proportions.

Although the concentration of sulfuric acid in the Erlenmeyer flask is not the purest, it is still very easy to deal with Xu Li, and there is no difficulty at all.

Mr. Yang talked about how to dilute concentrated sulfuric acid on the stage, not to pour it directly into it with water, not only will it release a lot of heat, but the key is that it will splash around, straight to your eyes, and even the spectacle lenses will be corroded when the time comes, and the polymer material of resin is prone to chemical reaction.

As for the correct method, the book also mentions that concentrated sulfuric acid is poured into a beaker filled with water, and a glass rod is used to drain the water.

Meng Ke didn't care about any of this, and he didn't have much interest in it. And the whole thing is the plan he wants to complete next.

While everyone was listening carefully, he sneaked under the desk. "Hey, who hasn't washed his feet for a few months, and my head is about to be unable to support it from lack of oxygen."

In desperation, he had to cover his mouth and nose with his hands, as if he was isolated from the world. It's really a crime, in order to let Xu Qian taste the pain as soon as possible, he can endure these small difficulties.

It took a long time to stumble to Xu Li. And Wang Yan was sitting not far from him, he had to be careful, otherwise if he accidentally hurt her, Meng Ke's heart would crumble.

"Brother Qi, what are you doing, you seem to be quite serious."

Those who come are not good, and those who are good do not come. The weasel gave the chicken a New Year's greeting, and he didn't have a good heart, so he didn't go to the Three Treasures Hall for nothing, and it is estimated that Meng Ke must have come to copy my chemistry paper this time. What I worked so hard to write was taken away by others, and it felt a bit of a bit of a take-off to say anything.

"Don't you see that I'm studying knowledge, are my eyes open so wide to vent?" Xu Wei gave him a perfunctory word, and then calmed down and used the test tube brush to clean the dirt in the silver mirror reaction.

He wouldn't be able to refine real pure silver, and if he could, he would sell it at the market for three or four catties, and maybe he could make a lot of money.

This Xu Qian is really no longer the boy he was at the beginning, the change is still quite big, since having such a beautiful girlfriend as Wang Yan, his waist has become hard, his legs are no longer cramping, and even the tone when he speaks, like a mosaic, makes you can't guess how people scold you.

I bear it, if this wasn't for the class, Meng Ke would have beaten him up as a basketball a long time ago. A small character who dares to fall in love with such a great and supreme representative of the English class, his kid must be lucky.

In this world, when will it be your turn to be so arrogant, no matter what, whether others can swallow this breath, Meng Ke can't swallow it anyway.

As he spoke, he picked up the concentrated sulfuric acid that had been contained in the beaker for a long time, and when he looked at it from a distance, it was as clear and transparent as mineral water. In chemical terms, it is a colorless and odorless liquid, and other students will not notice anything.

"Xu Li, take a look, what kind of solution is this, it seems that there is some precipitated colloid at the bottom?" Just as Meng Ke was about to sprinkle it on his arm, his feet slipped, and a forward sliding friction was generated in an instant.

In the end, the reason is not caused by a banana peel. Of course, the pre-set trajectory has now undergone a shocking reversal of one hundred and eighty degrees, and the mouth of the cup containing concentrated sulfuric acid is also facing his face that specializes in eating.

At this time, a lot of pictures appeared in his mind, and he also saw the scene of Ma Tiantian secretly eating bananas, needless to say, she must be the one who litters everywhere, and she will be punished for cleaning the entire laboratory building for a month. And Meng Ke didn't have time to think about this at all, because the concentrated sulfuric acid had already broken away from the bottom of the cup under the influence of gravity, and began to prepare to sway unscrupulously on his face.

He really regretted it now, but it didn't work, because he should always come, not come, but on the way back. The picture that came to mind flowed like the speed of light, and finally stopped, and was frozen in the class of "From Baicao Garden to Sanwei Study".

This text was written by a writer with a pen name named Lu Xun, whose original name was Zhou Shuren. I remember that during this class, he was still asleep, and was called up by the teacher and scolded him severely. No, it doesn't seem to have much to do with this chapter, is this a memory disorder?

After a loud bang, Meng Ke fell heavily to the ground, and the concentrated sulfuric acid that he wanted to harm others was not wasted, and it was all splashed on his face. "Ah, it hurts!" The hot coal-like sensation was corroding his skin.

It was mentioned in the book that if you accidentally splash on the skin with a strong acid solution, you can only treat it with plenty of water. But there are no faucets nearby, so I have to go downstairs, and as for the small faucets on the laboratory bench, the amount of water stored is limited, and it is only used to clean the instruments.

Under the attention of all the students and teachers, Meng Ke covered his face and left, if he continued to class, the consequences would be unimaginable.

At this time, it was study time, and naturally there were not many people on campus, only students in physical education class were strolling around. Meng Ke wants to seize the opportunity and occupy the faucet as soon as possible. Just as he was about to arrive, he was halfway through the journey to bite the gold, and two sophomore young ladies rushed over from the corner, turned on the faucet and washed their hands.

I'm a manly man who stands up to the sky, so I can't be angry with two girls. He sighed, and suddenly thought of the most powerful being of the Demon Star Curse.

Without saying a word, he ran in the direction of the toilet, as if his face had begun to feel numb.

"Spell Witch, are you in there?" He shouted loudly to the third layer of the cubicle, and Meng Ke also learned from Wang Xifeng's realm of not seeing anyone but hearing his voice first. It's just that he shouted like this, but Cheng Biting Tie, who was frightened, quickly put away the mobile phone that was playing the game.

"Meng Ke, it turned out to be you, you almost scared me to death, what's wrong with your face?"

"Splashed with sulfuric acid, it's serious, do you know where the witch went, I need its help."

Cheng Yantie was naturally powerless in the face of this situation, he could only use the function of brain waves to get in touch with the spelling witch. Of course, it is incarnated as Yang Zelin, lurking in the classroom of the ninth class of the third year of high school. Faced with the sudden bad news, the curse witch had no choice but to leave his body in his seat, and the original spirit floated into the toilet.

After seeing Meng Ke's face, it immediately had a very evil thought. Without further ado, the spell witch directly summoned a black mask from his hand, and several monsters tattooed on it invisibly added a hint of evil. If you wear it for a long time, your heart will gradually become dirty and become a demon star in the real sense, and Meng Ke, a student in the ninth class of high school, will disappear forever in the long river of history.

With the strength of the curse witch, it will definitely restore him to his original appearance, but it also has its own ideas for doing so.

Since you really want to be disfigured, it is better to hide it completely with an ugly face to face the world, and there is no harm in living under the mask of darkness, at least it will give you some invisible comfort in your heart.

"Okay, I'll wear it." As he spoke, Meng Ke fused with the black mask, and when the light faded, he unexpectedly found that he couldn't take it off.
