"This..." the elder martial sister paused and said, "just be happy."


    Obviously, she thinks the research topic chosen by Du Xingyu is too whimsical.


    "Younger martial brother, don''t be busy making a decision." Pang Yan said, "well, I''ll report other people''s research topics first. Think about it a few more days and report later."


    ……


    After the laboratory group meeting, Bao Xian asked Du Xingyu curiously, "Du Xingyu, what do you think? You actually want to study cloning Tyrannosaurus Rex?"


    "This is impossible. Cloning monkeys and pigs is almost the same."


    "Don''t you want to graduate?"


    "I see what you mean," said Du Xingyu, "but the most important thing in the research is the process. I mainly focus on the problems encountered in the process of this research topic."


    "That''s right..." Bao Xian said silently, "but your goal is too high. Maybe the first step can''t be completed... Change it quickly while senior brother didn''t report it to you!"


    "OK, thank you for your reminder." Du Xingyu smiled and said, "I know."


    Bao Xian shook his head. Du Xingyu didn''t seem to have any idea to change his mind.


    ……


    In the evening, through online video, Pang Yan reported the topics of his younger martial brothers and sisters to his mentor Su Yutang.


    In the picture, an old professor in his seventies appears. He is sitting in a bright office, and the sun is just outside the window.


    At this time, Su Yutang was conducting academic exchanges at Stanford University in the United States. He glanced at the content of the subject and asked, "there is still one left?"


    "Yes, there is a younger student. I asked him to choose a new subject," Pang Yan replied.


    "Who? What subject did he choose?" Su Yutang asked. Many of his students can''t remember their names sometimes.


    "Du Xingyu, the one who was unconscious a few days ago," said Pang Yan. "Didn''t you send the newly unearthed Tyrannosaurus Rex ossification stone to the laboratory? He said he wanted to study the cloning of Tyrannosaurus Rex. I asked him to think about it again."


    "Do you think this topic is too impractical?"


    "How to clone Tyrannosaurus Rex?" Su Yutang said with a bright look in his eyes. "I haven''t seen such a creative idea for a long time!"


    As a top scholar in the field of biology, Su Yutang''s idea is very advanced. He said: "my biggest feeling when I come to Stanford University is that the students here dare to think and do anything!"


    "We also need such students in Peking University. We should not be confined to how to complete the task, but to pioneering research and development... If Du Xingyu still insists on studying this subject, let him choose this one. Let him study the T-Rex skull fossil."


    "What matters is the process, not the result. Maybe he made new discoveries in the process of studying this subject."


    "OK, I see." although Pang Yan said so, he still thought that Du Xingyu must have failed to recognize the difficulty of his subject at the beginning and would give up soon.


    However, when Pang Yan came to the laboratory the next day, Du Xingyu had written the application for the subject.


    "You still decided to study how to clone T-Rex?" Pang Yan was surprised.


    "Yes, elder martial brother, I have thought it over!" said Du Xingyu.


    Pang Yan wanted to give more advice. Thinking of Su Yutang''s words, he said, "well, you can choose this topic. The teacher said that T-Rex skull fossils can be studied for you, but you must protect them!"


    "This skull fossil is quite rare. There is cartilage tissue left on it. Now the world can''t find a second one so complete!"


    "I know! I will protect it!" Du Xingyu nodded.


    He immediately began to study the Tyrannosaurus Rex skull fossil. The first thing Du Xingyu had to do was sequence the samples.


    To clone Tyrannosaurus Rex, we must first know the genetic information of Tyrannosaurus Rex (DNA fragment with genetic information).


    Su Yutang''s biological laboratory is a national key laboratory with relatively complete equipment, and most biological experiments can be carried out.


    Du Xingyu didn''t know whether he could get the complete genetic information of Tyrannosaurus Rex.


    After the death of organisms, DNA will begin to decay. Factors such as body cells, intestinal cells, soil microorganisms, ultraviolet radiation and so on will lead to DNA degradation. Oxygen and water also chemically alter DNA, causing DNA strand breaks.


    Under special circumstances, DNA can be preserved for millions of years. But Tyrannosaurus rex was a creature 65 million years ago, and it is almost impossible to preserve complete DNA information.


    So far, scientists all over the world have not obtained complete dinosaur genetic information, only scattered DNA fragments, and can not determine whether these genetic information is dinosaur or from other organisms.


    Du Xingyu established a "T-Rex gene puzzle" simulation project on the science and technology simulator.


    He put the genetic information monitored from fossils into the technology simulator and turned it into a puzzle.


    "I''m lucky. There are a lot of DNA fragments preserved in the cartilage tissue of this Tyrannosaurus Rex skull fossil." Du Xingyu obtained a large number of gene fragments through a large number of tests.


    But it''s just a dream to spell out the complete genetic information of Tyrannosaurus Rex with these.


    Du Xingyu also needs more information. In the name of Su Yutang biological laboratory, he sends e-mails to biological laboratories around the world that study dinosaur genes to get some information about gene fragments of Tyrannosaurus Rex or other dinosaurs.


    Other dinosaur genetic information can be used for comparison.


    Some of these laboratories refused him, and others provided help, allowing Du Xingyu to further enrich his data.


    Now Du Xingyu has a pile of chaotic and missing gene puzzles, in which there are many mistakes.


    Anyone who wants to get the DNA sequence of Tyrannosaurus Rex from it is afraid that it is still difficult to go to heaven.


    Du Xingyu has a technology simulator, which is not helpless.


    On the technology simulator, he can directly select a DNA fragment for simulated expression.


    "Tyrannosaurus Rex is a bipedal carnivorous dinosaur, that is, theropods, and birds evolved from theropods. I can compare the genomes of similar birds for gene modification and supplement..."


    This is bound to be an extremely cumbersome work, which needs to collect a large amount of information, and the technology simulator also needs to be simulated repeatedly.


    Du Xingyu is busy all of a sudden. At the same time, he also needs to start biotechnology publicity and obtain energy points to complete the simulation experiment.


    As a "newcomer" with little popularity in the world, Du Xingyu decided to publish his vlog (video log) on the hottest short video social media "Xingguang" here.


    He first registered an account. In the previous world, Du Xingyu was called Earth observation. This time, he planned to be called "creator".


    System prompt: "the nickname has been registered, please modify the nickname."


    Du Xingyu had no choice but to add vlog and four English letters after the "creator", and then began to publish his first video log.


    "Hello, I''m Du Xingyu, a graduate student in the Department of biology."


    "I want to do one thing, clone Tyrannosaurus Rex! Yes, you heard right. It''s the kind of Tyrannosaurus Rex you think."


    "Tyrannosaurus Rex is a carnivorous dinosaur that lived in the late Cretaceous period, 68.5 million to 65 million years ago. It is also one of the last extinct dinosaurs!"


    "The adult Tyrannosaurus Rex is about 11.5-14.7 meters long, with an average hip height of about 4 meters. The highest head height is nearly 6 meters, the average weight is about 9 tons, and the maximum head length is about 1.55 meters. The bite force is generally 90000-120000 newtons, and the maximum at the end of the mouth is about 200000 Newtons. At the same time, it is also the strongest carnivorous dinosaur."


    "It''s very difficult to clone such a land overlord. I have a T-Rex skull fossil containing T-Rex cartilage. I''m going to start with it first..."


    In the first video log of Du Xingyu, he briefly introduced his plan and sequenced the skull fossils of Tyrannosaurus Rex.


    The video was sent out. As a new video, the platform gave it a certain amount of exposure.


    Soon, someone commented on this video.


    Xinfeiyang: "now everyone has fire! Why don''t you say you want to make Altman? Clone T-Rex? That''s ridiculous!"


    According to Yi Jinren, "is this T-Rex skull a model? Where did you buy it? I want to buy one and put it at home."


    The moon sets silently: "are you really a graduate student? I feel it''s all fake!"


    Steamed stuffed bun: "well, brother, starlight recommended a friend''s video. I brushed your video. Come on!"


    This steamed stuffed bun is Du Xingyu''s current roommate Bao Xian. Because of the acquaintance recommendation mechanism of the software, he brushed the content released by Du Xingyu.


    Not only him, some friends in Du Xingyu''s address book also brushed the video he released. But most people just take a silent look and don''t comment.


    Du Xingyu''s first vlog has less than ten comments and only a dozen likes.


    He didn''t think so. He updated it every week. Most of the content was about the progress of cloning Tyrannosaurus Rex.


    A month later, the technology simulator reminded: "T. rex''s gene map is 63 percent complete."


    "It''s too difficult." Du Xingyu felt that it was more troublesome than designing a Star Destroyer. If it weren''t for the unlocked functions of the science and technology simulator, he estimated that he couldn''t even complete this 63%.


    "Too little, too little genetic information." when Du Xingyu was at a loss, he received an email from his mentor Su Yutang.


    "These are some research materials of Edward kerton, a famous dinosaur scientist in North America, which may be useful to you."


    Du Xingyu opened it and found that it was actually a sequencing information of dinosaur skin tissue genes. This is an extremely valuable information. Tens of millions of years ago, a dinosaur accidentally fell into the swamp. Due to the influence of sulfide and other substances, its skin did not completely disappear and retained a small piece of skin tissue fossils.


    The biological laboratory in North America tested the genetic information of these skin fossils. Su Yutang also learned that there was such a thing during academic exchanges, so he asked for a copy for Du Xingyu.


    For this information, the other party is not stingy. Because they have limited genetic information, there is no breakthrough. Including the previous T-Rex skull fossils, which have been tested by biological laboratories in North America for a long time. They thought it had no practical value and gave it as a gift.


    But this is good news for Du Xingyu. He immediately sent an email to thank his mentor and imported this information into the technology simulator.


    Although this is not the skin tissue information of Tyrannosaurus Rex, it still has high reference value.


    "Gene comparison is under way..." the science and technology simulator soon found useful gene information, and then improved the Tyrannosaurus Rex gene map according to this information.


    "The gene map of Tyrannosaurus Rex is 92% complete!" this information made Du Xingyu directly pull the progress into a big part.


    "For the remaining 8%, while filling in the information, we speculate and simulate..."


    It took Du Xingyu another time to finally simulate the gene map of Tyrannosaurus Rex. But the result he got was not the only one, but more than 10 million, because the lack of information he had was too serious.


    Science and technology simulator: "start to simulate the synthetic genome... 12.34 million results have been generated, 9.87 million results have failed directly, and further screening has been started."
