The results of the half-term exam came out, and the first place in the grade, Yang Fan's name soon spread throughout the campus.

Koko full score, full score essay, etc., are rumored to be miraculous.

However, most of them don't believe that this is true, after all, with a perfect score in Koko, if you don't cheat, you can't do it at all.

"Have you heard, this afternoon, a new member of the team of scientists of the Pearl River Academy of Science is coming to our school to give a lecture!"

"I also heard that it is said to be a biology expert, Tu Dazhi. ”

Tu Dazhi specializes in genetic engineering, and he has already conquered ten genetic diseases. ”

……

In the classroom of the fifth class of the third year of high school, Yang Fan fell asleep on the table, but the classmates in the class were talking nonsense.

"Tu Dazhi! It turned out to be Tu Dazhi!" On the side, Xie Xiaofeng couldn't help but exclaim as he listened to the discussion of his classmates.

Xie Xiaofeng loves to learn, especially biology, and he also knows some biologists in Huaguo.

Xie Xiaofeng knows very well that in this country, Tu Dazhi is an authority on genetic engineering, and if he can listen to Tu Dazhi's lecture once, he will definitely benefit a lot.

"I didn't expect Tu Dazhi to come to our school. On the other side, Ding Xiaoxiao also showed a hint of a smile on his face.

Ding Xiaoxiao pushed Yang Fan and said, "Yang Fan, let's go to Tu Dazhi's lecture together in the afternoon." ”

"Yes, yes, Yang Fan, let's go together. Xie Xiaofeng hurriedly poked his head out and snorted.

Yang Fan opened his eyes dimly, glanced at Ding Xiaoxiao and Xie Xiaofeng with a confused expression, and didn't bother to ask, so he nodded directly.

Anyway, Yang Fan also sleeps in the classroom, and he can still sleep when he goes to listen to lectures, but he just sleeps in a different place.

……

The morning class ended quickly, and after the lunch break, Tu Dazhi's lecture was carried out under the strict management of the teachers and students of the school.

Zhujiang No. 1 Middle School, the school auditorium, decorated with brilliant lights, the hall of thousands of people, full, even, some students can only hold a few pieces of paper, pad under the buttocks, sit on the ground.

In the first row of the auditorium, Yang Fan, Xie Xiaofeng, and Ding Xiaoxiao sat in the center.

After all, Ding Xiaoxiao is the daughter of the principal Ding Yuan, and it is naturally easy for her to come to the auditorium to get a place in the first row.

In the first row, Xie Xiaofeng and Ding Xiaoxiao sat up straight, looking forward to it, looking out of the door expectantly.

However, Yang Fan was lying on the table and falling asleep.

"Isn't this Yang Fan from the fifth class of the third year of high school? I heard that he took the first place in the half-term exam, and he got a perfect score in the subject. ”

"Full score? It's obviously cheating, just like him, how can he get a full score in the science exam?"

"It must be cheating, if not all of it, at least half of it. ”

……

In the auditorium, after the students saw Yang Fan, they all pointed at Yang Fan and sneered.

At the same time, outside the auditorium, an old man with white hair, a plaid shirt tucked into his trousers, and a bunch of keys hanging on his trouser belt, walked in slowly, surrounded by Li Aiguo and others.

"Tu Dazhi! It's the biologist Tu Dazhi!"

"Oh my God, I finally saw Tu Dazhi Zhenren!"

"Professor Tu, can you sign me!"

……

In the auditorium, when the students saw Tu Dazhi walk in, they screamed at the top of their throats as if they had been beaten with chicken blood.

Tu Dazhi put his hands behind his back and smiled at his classmates, and then walked unhurriedly to the podium directly above the auditorium, while Li Aiguo and others saddled all the way and did not dare to slack off.

"Hello everyone, I'm Tu Dazhi. Tu Dazhi stood on the podium, supported the lectern with both hands, and said a word to the microphone on the lectern.

As soon as Tu Dazhi spoke, the classmates became more and more excited, and some female classmates even held their chins with their hands, and their eyes were starry, as if they had seen Oba.

Tu Dazhi smiled, reached out and took out a USB flash drive from his pants pocket, and said, "Patriotic, please help me connect the USB flash drive to the projector." ”

"Yes, yes. Li Aiguo bowed and nodded, hurriedly took the USB flash drive in Tu Dazhi's hand, and then connected to the computer.

At the same time, Li Aiguo hurriedly ran to the side, brought a cup of tea for Tu Dazhi, and said with a smile: "Professor Tu, please drink tea." ”

"Thank you. Tu Dazhi nodded at Li Aiguo, took a sip of tea, then looked at the students in the auditorium, and said: "Students, since I am here today, then I will explain to you the current genetic engineering technology." ”

Tu Dazhi picked up the laser pointer, turned to the side of the students, pointed at the projection in the auditorium with the laser pointer, and said: "As we all know, China's genetic engineering has entered the ...... now"

As he spoke, Tu Dazhi switched the speech materials prepared in advance and explained many useful dry goods to the students.

The students listened and nodded their heads in agreement.

At this time, Yang Fan seemed to have woken up, stretched his waist, straightened up, and looked at Tu Dazhi on the podium.

Yang Fan just listened casually, then shook his head, what Tu Dazhi said was right, but the content of what he said was too shallow and useless.

"However, although China's genetic engineering technology is now very perfect, if you want to be like a science fiction movie shot in the United States, if you are bitten by a spider, you will mutate genetically and become Spider-Man. ”

"And a trip to outer space, exposed to cosmic ray radiation, and become a transparent person, a fire man or something, that's all nonsense. ”

"The genetic mutations in the US science fiction movies are all a misunderstanding of the existing genetic engineering, and the genetic engineering technology in the world is simply not like the one in the US movie. Tu Dazhi held the laser pointer in his hand and spoke vigorously.

The students in the auditorium nodded their heads in agreement.

The students have all studied biology, and some basic biological knowledge is still very clear, like those science fiction movies sent by the United States, they are all deceptive.

"Huh. At this time, Yang Fan in the first row shook his head and laughed.

Yang Fan's laughter was actually not loud, but it was extremely harsh in the quiet auditorium.

Even, as soon as Yang Fan smiled, there were already hundreds of angry eyes in the auditorium towards Yang Fan.

"What's the matter with Yang Fan? Now Professor Tu is explaining serious scientific knowledge to us, but Yang Fan is laughing. ”

"Don't pay attention to Yang Fan, he is just grandstanding, does he understand scientific knowledge?"

"Yang Fan cheated and won the first, and he really regarded himself as a character?"

……

In the auditorium, the students sneered at each other, looked at each other coldly, and even Li Aiguo on the podium walked down and said to Yang Fan in a deep voice: "Yang Fan, you go out!"

The second watch, there are only two changes today.
