The breath exhaled from Mr. Yang's nose became thicker and thicker, and his anger was estimated to be getting stronger and stronger. Isn't it a challenge to his authority to say this openly in class?

Although these words came from Jiang Mengying's mouth, how Han Chen's attitude looked like this was really what he said.

"Very good, very good...... faintly, the students in the classroom seemed to be able to hear Teacher Yang gritting their teeth.

Jiang Mengying had a sly smile on the corner of her mouth, and with a virgin fragrance on her body, she leaned into Han Chen's ear and whispered, "If you can pass the level of Old Man Yang, even if you win...... Come on. ”

Han Chen laughed for a while, and looked back at her meaningfully.

Jiang Mengying winked playfully at Han Chen, turned her gaze to Liu Qingluo, who was glaring at her, and raised her eyebrows. Silk Banner smiled triumphantly on his face.

Liu Qingluo's hateful teeth itched, and her eyes were full of anger, if she could, she really wanted to scratch her nails twice on that beautiful face. Jiang Mengying provoked trouble like this, didn't she push her little brother Chen into the fire pit? Xiao Qingluo secretly hated in his heart, and at the same time, he was secretly anxious.

The reaction was mixed. Some are full of pity, some are gloating and watching a good show, and some are looking at him like a stupid X. When he met the old-fashioned and hot-tempered Teacher Yang, no one thought that Han Chen would be able to pass this level, and if he couldn't pass the level, he wouldn't be able to fall behind.

What he said was outrageous. God doesn't forgive, no one will think that the poor hanging silk at the bottom of the grades can still turn over the sky.

Speaking of which, this old man said that it is very good to speak, and it is very difficult to speak badly, and he is a very principled person. If Han Chen couldn't prove his strength today, he didn't say much.

I'm afraid, compared to the demerit punishment, it is quite light. Thinking about being bombarded with fatigue for hours with great reason, it is really better to have a demerit punishment.

"Han Chen, then you can memorize biomolecules. You don't need to memorize it backwards, you just need to start with the preface. All you need to do is memorize the first twenty pages, and word for word. You don't have to use it for my classes in the future. If you can't memorize it, I won't punish you. I just hope you can know what a student should do. My old man has been teaching for so many years, and he has never been said like this, or I am really old before someone dares to bully me. ”

The old man pushed the glasses in front of him, and his tone slowly calmed down. The voice is calm and frightening. There was a mixture of disappointment, heartache, and a hint of humiliation.

Teacher Yang's performance made a hint of complexity appear on everyone's faces. Maybe everyone had the mentality of watching a good show before, but after thinking about it carefully, they felt that what Han Chen said was really a bit excessive. It's more ugly than a slap in the face.

Everyone looked at Han Chen's gaze with a hint of annoyance. They knew that the teacher was genuinely angry. Even the mischievous Jiang Mengying realized that she had gone too far, and her face showed a hint of guilt.

After all, this teacher is a bit stubborn though. The idea is old, but he is a good teacher, even if he is a naughty student, he will respect him a little in his heart.

When Liu Qingluo saw this scene, he was anxious. Her body hurriedly leaned forward, wanting to stand up and explain to Han Chen, but she was stopped by Han Chen as soon as she moved.

Shaking his head at the girl beside him, Han Chen stood up. Looking back at Jiang Mengying, who had a complicated face, he turned his gaze to the teacher in front of the podium again, bowed and bowed before speaking:

"Teacher, then I'm ugly," said him, his face straightened, and then he said loudly:

"Molecular biology is the science that studies the structure and function of biological macromolecules at the molecular level, so as to elucidate the nature of life phenomena. Since the 50s of the 20th century, molecular biology has been the frontier and growth point of biology, and its main research areas include protein systems, protein-nucleic acid systems, and the center is molecular genetics and protein-liposomes, that is, biofilms. ”

"In 1953, Watson and Crick proposed that the double helix structure model of DNA molecules was a sign of the birth of molecular biology. The study of the structure and function of biological macromolecules, especially proteins and nucleic acids, is the basis of molecular biology. The application of theories, techniques and methods in modern chemistry and physics has promoted the study of the structure and function of biological macromolecules, resulting in the vigorous development of molecular biology in the past 30 years. Molecular biology is closely related to biochemistry and biophysics, and the main differences between them are ......"

Regardless of whether he was forced by Jiang Mengying or not, at this point, if Han Chen quibbled or retreated, then he would be an immortal emperor in vain, and he would be insulted and disrespectful to the teacher on stage.

As he spoke, everyone's eyes were slightly weird, they didn't expect Han Chen to really start memorizing, and it seemed that there was nothing wrong with memorizing, at this time, most people suddenly realized that they began to pay attention to the molecular biology textbook in their hands, the more they looked at it, the more strange their faces became, and the more they listened to Han Chen's recitation, the more shocked their eyes became.

The entire classroom was silent, except for the sound of Han Chen's recitation, only the sound of flipping books remained. Everyone focused on the textbook in their hands, and no one was willing to look away. They are afraid of missing every word in it.

It wasn't until the bell rang for the end of class that everyone woke up from their shock, and their gazes at Han Chen at this time had already begun to differ, and in about half an hour, Han Chen had memorized twenty pages. The main thing is that it's really good. Even the punctuation pauses can be clearly felt. If there is enough time, everyone believes that Han Chen will definitely be able to memorize the entire book easily.

Jiang Mengying opened her mouth wide and looked at Han Chen standing in front of her, stupidly not knowing what to say. Is this still human? That was the only thought in her mind at this point, or the only thought in the hearts of everyone in the classroom.

"No need to memorize!" Old man Yang stretched out his hand to stop Han Chen, who was still reciting, and the old man was also shocked by Han Chen. It's not a sentence or two, it's almost half a book, and it's good to be able to memorize the main content, not to mention that every word and symbol is not bad.

"Maybe the teacher is really old. In the future, you can not use my classes. His voice was a little weak, and he put the textbook in his hand on the desk, and he stood sideways on the table, looking much older at this time. He felt that he had taught for half his life, and that the book had been taught in vain. When he encounters a monster like Han Chen, he really can't teach it.

Seeing this scene, the whole classroom was silent for a while, and a complex emotion rose in everyone's hearts.

Looking at the teacher who was a little lazy and devastated, even if Han Chen was once an Immortal Emperor, he was not disturbed by everything. But at this time, I still feel a little complicated and apologetic. In his previous life, he was very impressed by this teacher, this is a teacher with real virtue. He also really dedicated his life to the cause of education.
