"Who am I?" Du Xingyu''s mind was in a mess. The science and technology simulator transmitted a message to his brain. He digested it for a long time before he straightened out his mind.
The world is very similar to the world before he graduated from college in his "last life". The history and culture are roughly similar, with only a few different places.
In this world, his name is Du Xingyu. He is 24 years old. His parents died in a car accident when he was a child, so he basically had no relatives.
Du Xingyu had excellent grades since childhood. He was once admitted to Peking University, the top university in China, with the first score of the college entrance examination in the city. Studying in biology department, he is currently in the first grade of graduate student.
He is weak and sickly. Recently, he has been studying and working continuously for a period of time because of the tension of the project. After writing the paper all night last night, I stood up in the morning and suddenly fainted. Fortunately, I was found by my roommate and sent to the school hospital.
Now several people beside the hospital bed are his roommates, senior brothers and sisters. As for the crying little girl with "pear flowers with rain", she is Su Ziyun, the granddaughter of tutor Du Xingyu.
Du Xingyu''s mentor, Su Yutang, a famous professor of biology at Peking University, often leaves Su Ziyun to several of his students because he doesn''t have time to bring his granddaughter. Su Ziyun is closest to Du Xingyu, so this scene appears.
"That''s what you said. Don''t grab snacks with me next time." Du Xingyu''s voice suddenly came. The little girl raised her head and stared at him with big tearful eyes for a few seconds. Then she broke her tears into laughter and said, "great, you''re okay!"
She hesitated for two seconds and added, "I''ll only eat half of your snacks next time!"
"Du Xingyu, you finally wake up!" an old man came forward and said. He is Du Xingyu''s senior brother and one of the doctoral students led by Su Yutang, Pang Yan.
"Are you all right?" Bao Xian, Du Xingyu''s classmate and roommate, asked with concern.
"It''s OK, but I''m overworked." Du Xingyu sat up and said sorry, "it''s worrying everyone."
"You''re all right. You almost scared me to death!" a student in gray patted his chest and breathed a sigh of relief. She is Du Xingyu''s graduate student in the same period, Yang Mu.
"I have to send a message to the tutor first, and the tutor said he would come to see you." Pang Yan immediately sent a message to the tutor and told him that Du Xingyu had woken up.
……
Du Xingyu did another simple examination. The doctor confirmed that he was just overworked and had no big problem, so he was released.
"You can rest a few more days," Pang Yan told him. "When you have a good rest, you can choose another topic."
"Brother Xingyu, you must have a good rest. You said you would take me to roast chicken next time I have a holiday!" Su Ziyun seriously reminded.
"I know, snacks!" Du Xingyu rubbed her little head and smiled.
"That''s it. Du Xingyu, we won''t bother you. If you have any discomfort, go to the hospital early for examination." Yang Mu said.
Everyone said goodbye one by one. Du Xingyu and his roommate Bao Xian returned to their two room graduate dormitory. Bao Xian is also a graduate student majoring in biology, but his research direction is slightly different from that of Du Xingyu.
Du Xingyu''s research direction is mainly genetic engineering, while Bao Xian''s research direction is biochemistry and molecular biology.
"Brother, don''t bother yourself too much. You''re just studying. What''s the hurry?" Bao Xian said while turning on the computer: "our mentor Su Yutang is a top biology professor. Study with him for a few more years to ensure a future!"
"Ha ha." Du Xingyu didn''t say anything. He said, "thanks to you today. I''ll invite you to dinner tonight."
"Do you have money?" Bao Xian make complaints about it.
"Enough," said Du Xingyu. When he was admitted to the University, the high school awarded him 200000 yuan. During the University, various scholarships continued. Now living in school, I don''t worry about my food and drink.
"OK, I''ll go out first and see you in the evening." Bao Xian went out and there was only Du Xingyu in the dormitory.
Du Xingyu looked in the mirror and looked at his young face and slightly thin body. He couldn''t help being in a trance.
In another world, he is the supreme commander of the human Guardian alliance, commanding the highest combat power of mankind, the space fleet.
And here, he is a poor student again, as if he were separated from the world. That''s the feeling!
Du Xingyu has been in this world for a few days and is generally familiar with the situation here.
He did not forget his purpose. Du Xingyu opened the second experiment of scientific and technological civilization on the science and technology simulator.
"This era of science and technology, I named it the era of biotechnology."
"The goal this time is to make human biotechnology explode and break the limit of human life!"
Science and technology simulator: "science and technology simulation, test site and No. 2 earth space-time have been established for the era of biotechnology. The main development of science and technology is biotechnology."
Under the science and technology simulator, new branches of science and technology have emerged.
Such as molecular biotechnology, genetic engineering, cell engineering, biochemical engineering, microbial engineering and so on.
Technology simulator: "please establish a new research project as soon as possible to obtain energy points."
When he came to this world, the energy points of the technology simulator had been consumed, and Du Xingyu had to start again.
Up to now, Du Xingyu has a little understanding of the greatest use of this "energy point". When he is spreading some kind of technology, his behavior will affect the whole era!
Just like in the last interstellar era, decades later, under the influence of Du Xingyu, many people became space soldiers and scientists and opened space commerce. It can be said that he influenced an era and promoted the formation of the interstellar era!
……
While recuperating, Du Xingyu is also digesting and learning biotechnology knowledge. With the accumulation of the last era, he soon mastered most of the biotechnology knowledge.
A few days later, he received Pang Yan''s notice to hold a laboratory group meeting.
The key biological laboratory led by Su Yutang usually has a group meeting once a week. Su Yutang will attend when he is free. When he is not free, he will let his student Pang Yan preside over it.
Mainly about some research process, literature, report and so on.
When Du Xingyu arrived at the laboratory, he saw several students moving things carefully. It looked like a fossil specimen or a fragment.
"What is this fossil?" Du Xingyu asked curiously.
"Dinosaur fossils," Yang Mu said, "to be exact, they are fragments of the skull of Tyrannosaurus Rex."
"Where did this come from?" Du Xingyu said strangely.
"It was given by someone else." Yang Mu said, "this is a fossil found in North America not long ago. It is particularly precious. The remains of intact chondrocytes were detected in its skull fragments, which may contain detailed Tyrannosaurus Rex DNA information. This is a gift from Stanford University to Peking University. We can use it to study the residual DNA information."
"So it is." Du Xingyu nodded. "That''s really valuable."
65 million years have passed since the age of dinosaurs. For such a long time, DNA information has long been lost. Even in fossils, only fragmentary DNA fragments can be found, and it is not even certain that they must be dinosaurs.
However, there are complete chondrocyte residues on this Tyrannosaurus Rex bone, so it is possible to find complete Tyrannosaurus Rex DNA information, so this Tyrannosaurus Rex bone fragment is indeed worth thousands of gold!
Seeing this Tyrannosaurus Rex skull, Du Xingyu''s heart moved. If we can collect the DNA information of Tyrannosaurus Rex and obtain the completed Tyrannosaurus Rex genome, we will have the opportunity to replicate dinosaur embryos. The gene editing and cloning technology involved are of great significance to the development of biological science.
The laboratory group meeting began soon. There were more than 30 people. Du Xingyu, as the youngest student, sat at the back.
Pang Yan said above, "let me talk about our study last week..."
Pang Yan has no passion and serious language. He only spoke for half an hour, and the members of the group were a little sleepy.
Pang Yan didn''t think so and insisted on finishing his speech.
Several students in the same period with Du Xingyu ignored it. They were relieved and finally finished.
"Well, here''s another thing," Pang Yan said. "The youngest junior brothers and sisters, the teacher asked me to inform you that you can start choosing your own graduate project."
"Finally, we can choose course questions!" the students in the same period have been looking forward to it for a long time. If we choose the topic early, we can complete it early and write graduate thesis or something.
This is one of the most important links in their graduate career.
Pang Yan continued: "I think you all have decided what topics to choose? I suggest choosing the mature topics in our laboratory, so as to facilitate your research."
If you choose a mature subject, you will avoid many detours, and there are tutors and senior brothers and sisters who can guide you, which is also the choice of most students.
"I choose the direction of gene editing." Yang Mu immediately said, "about artificial modification of nuclease."
Su Yutang''s laboratory is leading in gene technology.
"I''m also in gene editing," said another female graduate student. "It''s just the modification of plant genes."
Several students have chosen the direction of the subject, but Du Xingyu didn''t say.
Pang Yan said, "Du Xingyu, have you decided what subject to study?"
"Elder martial brother, I want to ask. Can the overlord dragon bone, a new material from the laboratory, be used for research?" Du Xingyu asked first.
"Well," Pang Yan thought for a moment and said, "the teacher told us to test the DNA information on it. Of course, we can study it."
"That''s OK," said Du Xingyu. "I want to study the T-Rex skull. As for my subject, it should be ''cloning T-Rex''."
"What? What did you say?" Pang Yan was stunned and asked, "Du Xingyu, do you want to clone T-Rex?"
"Make complaints about it too..." Yang Mu Tucao.
"Fortunately, the tutor is not here, or you will be criticized!" Bao Xian said.
"Younger martial brother, you can choose one." a senior sister said, "cloning Tyrannosaurus Rex is ridiculous. You mean it''s more reliable to study how to clone mammoths!"
"I just want to choose this, clone Tyrannosaurus Rex!" Du Xingyu said firmly. He chose it because of the difficulty. He didn''t come here to graduate, but to change the world!
