Chapter 130：

"On this question, my team and I did 280 experiments. The stability of plant fermentation and extraction far exceeds that of animal serum. For relevant data, please refer to the third part of the appendix." Li Zheng replied.

The crowd in the lecture hall stretched their heads, trying hard to see the information in the hands of the five people in the first row. Several prestigious scholars have already left their seats and stood beside the first row of five people.

With that expression, I really want to **** the information from the five people.

"Can you elaborate on the principle of artificial attenuation?" Xu Mingsheng asked.

Li Zheng nodded.

He turned around and put a simulated virus picture under the slide.

"Look at everyone, this is a virus model of the Doke virus. This artificial attenuation technology, I was inspired by a project that researcher Liu Sichao is doing, virus blocking. The structure of this virus model determines its spread in the human body. The way……"

The questions of the five people were followed one by one, and almost after Li Zheng answered one person's question, the other person's question was taken up without any breathing time.

However, Li Zheng was not at all flustered, his face was calm, and his tone of voice was not rushed, which made many seniors in the biological circle unable to help but admire.

This is probably the longest graduation defense. It took more than six hours from Li Zheng's report to the end of the defense. The five members of the instructor seat looked at each other, and they couldn't help showing a bitter smile on their faces.

Although the professionalism of the five people is beyond doubt, biopharmaceuticals is an esoteric subject. It is so easy to understand a project.

Just talk about Li Zheng’s polygram virus vaccine project. There is such a thick pile of information on weekdays. They don’t have a month. They can’t read it at all. If they want to thoroughly understand it, it may take three to five months. Still on the premise that Li Zheng explained.

It's not easy to ask questions.

Five people rummaged through it, and they could only ask these superficial questions.

Su Changzhi gave a dry cough, "Student Li Zheng, your performance is very good. Your project is not only outstanding in academic value, but also very rare in its practical application value. The people of Doman will thank you, and we at Xiangjiang University also have yours. Student, I am proud!"

When Su Changzhi talked about the back, he was obviously excited. He winked at Xu Mingsheng. Xu Mingsheng stood up with a smile and took out a red degree certificate from under the desk drawer.

He strode onto the speech stage, "This should have been awarded to you by President Su himself, but I won it. You are my student, and I personally give this to you. Thank you for choosing Xiangjiang University." Xu Mingsheng said sincerely.

Li Zheng bowed deeply to Xu Mingsheng, "I am also very grateful to Xiangjiang University for accepting me."

There was another warm applause in the venue.

Everyone in the guest table clapped their hands, but the expressions on their faces were not so good.

How Xu Mingsheng has been procrastinating is still unresolved, and finally waited until the reply was over, whether it was their turn to ask questions, these seniors in the biosphere had been holding back all afternoon.

Especially that Professor Fujigami from the University of Tokyo, can't wait to take Xu Mingsheng down.

As soon as Xu Mingsheng stepped on the first step, the atmosphere in the court became obviously different.

At the end of the defense, the reporters took out the guys who were eating, Xu Shi was suffocated, and the flashes were connected together, almost blinding everyone's eyes.

Li Zheng's eyes were slightly narrowed because of the strong light.

"Hello Li Zheng, I’m Fujigami’s work. I would like to ask whether the plants in your report will work against the Doc virus that already exists in the human body. I find that your plant extraction technology is different from the traditional technology. Did you invent a new technology? Can you discover your new technology?"

Fujikami ignored the dazzling flash, and rushed to the front row first.

Xu Ming got angry, "Professor Fujigami, today is Li Zheng’s graduation defense, not an academic sharing session. I hope you will pay attention to the impact."

Tengami ignored Xu Mingsheng's intention at all, but stared at Li Zheng with scorching eyes.

Li Zheng smiled, "To fight against the Dock virus in an all-round way, we must take two paths to prevent and cure. Both hands must be hard. The yew fir is used for first aid and the vaccine is used for defense. Now the only shortcoming is the dormancy of the human body. Virus treatment. This is also the next step I want to take."

The newly discovered fermented plant extracts can be used for artificial attenuation and are also effective against viruses in the human body. However, during the experiment, Li Zheng discovered that while the plant fermented extract effectively treats viral infections, it also stimulates the virus and strengthens its activity.

Doc virus is a virus with an extremely long incubation period, and some luck may not even occur in 30 to 40 years. The fermented plant extracts will not only kill the dormant virus but also accelerate its activity.

The degree of this is really difficult to grasp. Li Zheng had all thoughts about it. When the vaccine was just entering the human clinical stage, he set up a joint project team with Merck in the name of Li Zheng's laboratory to conduct drug research.

Li Zheng can predict that this will be a long and difficult process.

"As for the refining technology you mentioned, yes, it is somewhat different from the traditional technology, just some practical tips. This is nothing to keep secret, if you are interested, I can record a video, as you come to join me this time A small gift for graduation defense." Li Zheng said with a smile.

Fujigami's eyes were full of colors. Although Li Zheng did not answer his first question directly, he understood the meaning of Li Zheng's words.

Seeing his colleagues in the back eager to move, he couldn't help but speak again: "Mr. Li Zheng, have you received the invitation letter from the University of Tokyo? Are you interested in teaching at the University of Tokyo? We can take the level of a professor as You are ready for the laboratory!"

Xu Mingsheng couldn't wait to throw this shameless person out of the venue, and now he started digging people in front of them, when they were all muddled!

The students of Xiangjiang University were also filled with outrage, and there was a commotion in the venue. But Fujigami ignored the reactions of others and only stared at Li Zheng sincerely.

Li Zheng lowered his eyelids slightly, a hint of apology appeared on his face, "Sorry, I have no plans for this for the time being."

"Mr. Li Zheng..."

"Mr. Li Zheng..."

There were guests present and reporters on both sides shouting Li Zheng's name. Li Zheng smiled and nodded one by one, without saying a word, and walked to the side door.

"Editor-in-chief, be careful." A reporter on the side quickly supported Zhao Qiuhua with eyesight.

Because of the reporters who kept squeezing forward, Zhao Qiuhua was unsteady and almost fell to the ground.

The little reporter who held her breathed a sigh of relief. You must know that the editor-in-chief Zhao is not only the editor-in-chief of their Xiangjiang Daily, but also their proprietress. If they bump into each other, they will have to eat. drop.

I don't know why she has to come. Even if Li Zheng is great and legendary, the editor-in-chief will not be able to take part in the news.

What's more, this big Buddha still has the golden young master of the Shen family in his belly.

The little reporter slandered in his heart, but the smile on his face became more sincere.

Zhao Qiuhua smiled politely at him. She didn't know why she came, but when she heard the news of Li Zheng's graduation defense, she asked for a place without even thinking about it.

Graduation defense, she didn't seem to have attended Li Zheng's graduation ceremony in elementary school or junior high school. Realizing this, Zhao Qiuhua couldn't tell how she felt. She knew that she was never a qualified mother, never was.

There was a surge in the stomach, and the feeling of vomiting became more obvious. Zhao Qiuhua covered his mouth and walked out hurriedly, not seeing Zhou Sitian's cold eyes behind.

After graduation, Su Changzhi and Xu Mingsheng took a group of guests to the Li Zheng laboratory after obtaining the consent of Li Zheng.

This time, the Hong Kong University invited most of the biosphere experts in Asia and the United Kingdom who have a say in vaccinology or biopharmaceuticals. They are obviously very interested in the younger generation of Li Zheng.

Especially after Li Zheng shared the tips of plant fermentation and extraction without any secrets, his interest became appreciation and friendship.

Xu Mingsheng also has the intention to pave the way for Li Zheng, personally bringing with him one by one introduction. This level of care makes Li Zheng not even moved.

It took everyone in Li Zheng's laboratory a whole day to entertain these seniors, but everyone did not feel tired at all. The juniors like Zhang Chao, Zhang Yuejun, and Zheng Lingling have not closed their mouths all day.

Those big guys who had only met in teaching materials talked to them kindly, even praised them, the three only felt that their bones were lighter.

When the crowd left, they were also very satisfied. Li Zheng kept his promise and recorded the tips into videos as gifts to everyone. It not only contains the techniques of plant fermentation and extraction, but also includes many practical tips. To a certain extent, it can greatly improve everyone's experiments. effectiveness.

These skills were also learned little by little by Li Zheng in his previous life from the experience of his predecessors. In that case, it is nothing more than the inheritance of knowledge.

"Li Zheng, this time you made our school a big show." Xu Mingsheng returned to Li Zheng's laboratory after sending away a group of guests.

Li Zheng poured a cup of tea for the teacher and placed it in front of him.

"I am a student of Xiangjiang University. It is my duty to win honor for my alma mater." He said with a smile.

"Duty! What a duty!" Xu Mingsheng laughed with his palms. He took a sip of his tea and said, "Students are going to graduate after all. Are you interested in becoming a real Xiangjiang University person?"

He stared at Li Zheng scorchingly, his eyes full of expectation.

Li Zheng lowered his eyelids and fiddled with the watch on his right wrist with his left hand. After all, this problem still came.

"Teacher..." Li Zheng said, considering the sentence.

Xu Mingsheng did not let Li Zheng continue, he waved his hand, "Think about it again, but don't have a psychological burden. Tell me tomorrow."
