Yilong, a chemistry teacher and a recent normal graduate of an ordinary university, is thin and small, and is often mistaken for a high school student. Wears a pair of black-rimmed glasses all year round, likes to play basketball, and still has a hint of childishness. I'm idle.,I often talk to my students about what I don't have.。

"It seems that everyone really wants to rest!" Yilong put down the chemistry textbook in his hand, stroked his glasses, and smiled meaningfully.

"Didn't you all sleep at noon?" he said, glancing around, in all kinds of postures.

"Yawn—" The back row yawned coldly in response.

"Hey—" I don't know who came another long sigh, as if admitting it, as if sighing at the darkness of the future.

"Okay, everybody, cheer up, go ahead and talk about this*, strong*, nitric acid .....," he said, turned around, and wrote a chemical equation on the blackboard.

"Eh, don't worry, everyone! Before you learn this equation, listen to the teacher tell a story. Yilong clapped his palms, intending to attract the attention of his classmates. Among them was Jian Zhen, who sat crookedly in the right position, his eyes stayed on the blackboard for less than a second, but he squinted at the afternoon class schedule, and couldn't help but yawn, almost knocking down his tears. It's so boring, chemistry class, English class, math class, it's really damn.

However, listening to Yilong's words, Jian Zhen barely mustered up his spirits to listen, listening to the story, it can add a little excitement, it is better than going to class all the time.

It is estimated that his words successfully attracted everyone's attention, and Yilong cleared his throat and began to speak.

"When my teacher went to college, he also studied chemistry, and there were only two ways to get out. As he spoke, Yilong stepped off the podium with his hands behind him, his eyes filled with a self-evident taste.

"One of them is definitely a teacher. Jian Zhen said to himself.

"The other is a chemist. Hearing Jian Zhenyi's words, the god on the side echoed in a low voice.

"One of them, that's right, it's what you just said about being a teacher!" Yilong looked at Jian Zhen with a smile, and the latter lowered his head weakly, avoiding the other party's gaze.

"The other one, it's not a chemist, it's a chemical worker!"

"Such a smart ear!" Jian Zhen said speechlessly.

"Damn!" it was God's turn to be surprised.

"Don't laugh, listen to the teacher, this chemist is not for everyone. ”

"In the United States, there was a chemist who had done a lifetime of scientific experiments, but in his later years he fell ill and had no savings to leave to his children, and then he relied on his superb knowledge of chemistry to start manufacturing*, and the production was the purest * in the world*...... This is also what we will learn in the next section, of course, hehe——! is not manufacturing*, interested students can go to preview it first. ”

"Okay, let's get down to business. The teacher can't be a chemical worker, so he can only come here to be a teacher. Like the female teacher in my office, it's all the same. ”

"Is it a baboon teacher?" asked a student council official.

"How can you call a girl such a name! Punish you for copying the formula on the blackboard a hundred times. ”

The latter had a desperate expression.

"Just kidding!"

The student council official immediately said to me, with a very relieved expression, "Not a hundred times, but a thousand times." ”

"Baboon teacher, do you know?" Jian Zhen asked the god beside him.

"It seems to be the chemistry teacher in the next class. Woman, what do you seem to be called?"

"How could anyone have such a strange name!"

"It's far away, anyway! When the teacher was making this, his hands were trembling, he was trembling!" After speaking, he made an exaggerated movement.

All of them showed expressions of understanding, fierce*, who is not afraid. Trembling is normal.

Jian Zhen can be regarded as understanding, Yilong has been doing it for a long time just to prove that his hands are shaking when he is **, such a small thing?

"Don't laugh, a little bit of your fingernail can blow up a big hole in the cave!" Yi Long gestured to his fingernail.

"Hmm——!?"

Very satisfied with the surprised reaction of the students, Yilong continued, "However, through the above chemical equation, we can see that this * structure is very stable, so the teacher said that the hand tremor is purely deceiving you." ”

"Hahahaha-" said and bent down, laughing from ear to ear, leaving a whole group of people confused.
