Technology's opening live broadcast to build rockets

"Who am I?" Du Xingyu's mind was in chaos. The technology simulator transmitted a stream of information to his brain. He digested it for a while before he sorted things out.

This world is very similar to the world in his "last life" before graduating from college. The history and culture are roughly similar, with only a few differences.

In this world, his name is Du Xingyu and he is 24 years old. His parents were unfortunately killed in a car accident when he was a child, so he had basically no relatives.

Du Xingyu had excellent grades since he was a child. He was admitted to China's top university, Peking University, with the city's top college entrance examination score. Studying in the Department of Biology, currently in the first year of graduate school.

He has been frail and sick since he was a child. Recently, he has been studying and working continuously for a period of time due to the tight project. After working on my thesis all night last night, I suddenly fainted when I stood up in the morning. Fortunately, I was discovered by my roommate in the same dormitory and was sent to the campus hospital.

The people beside the hospital bed are all his roommates, senior brothers and sisters. As for the little girl who is crying like "pear blossoms with rain", it is Su Ziyun, the granddaughter of instructor Du Xingyu.

Du Xingyu's mentor, Su Yutang, a famous biology professor at Peking University, often left Su Ziyun to several of his students because he had no time to take care of his granddaughter. Su Ziyun is the closest to Du Xingyu, so this scene happened.

"That's what you said, don't grab snacks from me next time." Du Xingyu's voice suddenly came. The little girl raised her head and stared at him with a pair of big, teary eyes for a few seconds, and then she burst into laughter. Said: "Great, you're okay!"

She hesitated for two seconds and then added: "I will only eat half of your snacks next time!"

"Du Xingyu, you finally woke up!" An old-looking man stepped forward and said. He is Du Xingyu's senior brother and one of Su Yutang's doctoral students, Pang Yan.

"Are you okay?" Bao Xian, Du Xingyu's fellow student and roommate, asked with concern.

"It's okay, but I'm overworked." Du Xingyu sat up and said apologetically, "I made everyone worry."

"I hope you're okay, you almost scared me to death!" A student in gray clothes patted his chest and breathed a sigh of relief. She is Du Xingyu’s graduate student at the same time, Yang Mu.

"I have to send a message to the instructor first. The instructor also said that he would come to see you." Pang Yan immediately sent a message to the instructor to tell him that Du Xingyu was awake.

…

Du Xingyu underwent another simple examination. The doctor confirmed that he was just overworked and had no major problems, and he was released.

"You should rest for a few more days." Pang Yan warned, "After you have rested, you can choose a topic again."

"Brother Xingyu, you must have a good rest. You said that next time I have a holiday, you will take me to eat roast chicken!" Su Ziyun reminded seriously.

"I know, snack food!" Du Xingyu rubbed her little head and said with a smile.

"That's it. Du Xingyu, we won't disturb you anymore. If you feel uncomfortable, go to the hospital for examination as soon as possible." Yang Mu said.

Everyone said goodbye one by one, and Du Xingyu and his roommate Bao Xian returned to their two-person graduate student dormitory. Bao Xian is also a graduate student majoring in biology, but his research direction is slightly different from 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 trouble yourself too much. You are just a freshman, why are you anxious?" Bao Xian turned on the computer and said: "Our tutor Su Yutang is a top biology professor. If you study with him for a few more years, you are guaranteed to have a bright future! "

"Haha." Du Xingyu said without saying anything cliché, "Thanks to you today, I'll treat you to dinner tonight."

"Are you rich?" Bao Xian complained.

"It's enough." Du Xingyu said. When he was admitted to college, his high school awarded him 200,000 yuan. During his college years, he also received various scholarships. Now that I live on campus, I don’t have to worry about food and drink.

"Okay, I'll go out first and see you in the evening." Bao Xian went out, and Du Xingyu was the only one left in the dormitory.

Du Xingyu looked in the mirror, looking at his young face and slightly thin body, and couldn't help but feel dazed.

In another world, he is the supreme commander of the Human Guardian Alliance, commanding the highest combat power of mankind, the space fleet.

But here, he was a poor student again, as if he had been in another world, this is how he felt!

Du Xingyu has been in this world for a few days and is generally familiar with the situation here.

He did not forget the purpose of his visit. Du Xingyu started the second technological civilization experiment on the technological simulator.

"I named this technological era - the "Biotech Era"."

"The goal this time is to make human biotechnology explode and break the limit of human lifespan!"

Technology simulator: "The "Biotechnology Era" technology simulation, test site, and Earth-2 space and time have been established. The main development technology is biotechnology."

Under the technology simulator, new branches of technology appear.

For example, molecular biotechnology, genetic engineering, cell engineering, biochemical engineering, microbial engineering, etc.

Technology Simulator: "Please establish new research projects as soon as possible to obtain energy points."

When he came to this world, the energy points of the technology simulator had been exhausted, and Du Xingyu had to start over.

By now, Du Xingyu somewhat understands the greatest use of this "energy point". When he spreads a certain technology, his actions will affect the entire era!

Just like in the last interstellar era, decades later, under the influence of Du Xingyu, many people became space soldiers and scientists, and started space business. It can be said that he influenced an era and promoted the formation of the interstellar era!

…

While Du Xingyu is recuperating, he is also digesting and learning biotechnology knowledge. With the accumulation of the previous era, he quickly mastered most of the biotechnology knowledge.

A few days later, he received a notice from Pang Yan to hold a laboratory team 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, his student Pang Yan will chair it.

Mainly talking about some research processes, documents, reports, etc.

When Du Xingyu arrived at the laboratory, he saw several classmates carefully moving something. It looked like a fossil specimen or fragments.

"What fossil is this?" Du Xingyu asked curiously.

"Dinosaur fossils." Yang Mu said, "To be precise, they are the skull fragment fossils of Tyrannosaurus rex."

"Where did this come from?" Du Xingyu asked curiously.

"It was given by someone else," Yang Mu said. "This is a fossil discovered in North America not long ago. It is particularly precious. Remains of complete cartilage cells were detected in its skull fragments, which may contain detailed DNA information of Tyrannosaurus rex. This is Stanford The university gave us a gift from Peking University, and we can use it to study the remaining DNA information."

"So that's it." Du Xingyu nodded, "That's really valuable."

Sixty-five million years have passed since the age of dinosaurs. During 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 belong to dinosaurs.

And this Tyrannosaurus rex skull actually has intact cartilage cell residues, and it is possible to find complete DNA information about Tyrannosaurus rex, so this Tyrannosaurus rex skull fragment is indeed worth thousands of dollars!

Seeing this Tyrannosaurus rex skull, Du Xingyu's heart moved. If the DNA information of Tyrannosaurus rex can be collected and the complete Tyrannosaurus rex genome is obtained, then there will be a chance to copy dinosaur embryos. The gene editing and cloning technologies involved are of great significance to the development of biological sciences.

The laboratory group meeting started soon. There were more than thirty people in total, and Du Xingyu, as the youngest student, sat at the back.

Pang Yan said above: "Let me first talk about our study situation last week..."

Pang Yan spoke without passion and his language was rather serious. He only spoke for half an hour, and the group members were already a little drowsy.

Pang Yan didn't take it seriously and insisted on finishing.

Several students who were in the same period as Du Xingyu ignored him and breathed a sigh of relief, finally finishing.

"Okay, here's one more thing." Pang Yan said, "For the youngest juniors and juniors, the teacher asked me to inform you that you can start choosing your own postgraduate topics."

"Finally, I can choose a topic!" Students in the same period have been looking forward to it for a long time. The sooner they choose the topic, the sooner they can complete it, such as writing a graduate thesis.

This is one of the most important aspects of their graduate careers.

Pang Yan continued: "I think you have all decided what topic to choose? I suggest choosing a topic that is mature in our laboratory, so as to facilitate your research."

Choosing mature topics will save you many detours, and you will also have tutors and seniors who can guide you. This is also the choice of most students.

"I choose the direction of gene editing." Yang Mu said immediately, "About artificially modifying nucleases."

Su Yutang's laboratory is relatively advanced in genetic technology.

"I am also interested in gene editing." Another female graduate student said, "It's just about modifying plant genes."

Several students chose the topic direction one after another, except Du Xingyu who did not say anything.

Pang Yan said: "Du Xingyu, have you decided on a research topic?"

"Brother, I would like to ask. Can the new material from the laboratory, the Tyrannosaurus rex skull, be used for research?" Du Xingyu asked first.

"That." Pang Yan thought for a while and said, "The teacher originally ordered us to find time to test the DNA information on it. Of course it can be studied."

"That's fine." Du Xingyu said, "I want to study the Tyrannosaurus rex skull. As for my topic, it should be 'cloning of Tyrannosaurus rex'."

"What? What did you say?" Pang Yan was stunned, and then asked: "Du Xingyu, do you want to clone Tyrannosaurus rex?"

"This is too ridiculous..." Yang Mu complained.

"Fortunately, the instructor is not here, otherwise I would definitely give you a scolding!" Bao Xian said.

"Junior brother, please choose one carefully." A senior sister said, "Cloning Tyrannosaurus rex is too outrageous. Even if you say that you are studying how to clone mammoths, it is more reliable!"

"I just want to choose this, cloning the Tyrannosaurus rex!" Du Xingyu said firmly. He chose it precisely because of the difficulty. He is not here to hang out until graduation, but to change the world!
