Zhang Wei took half a tube of blood from Jiang Shan's body, and then arranged for an intelligent robot to send Jiang Shan home. Considering Jiang Shan's great help to him, he also gave Jiang Shan a diluted genetic evolution liquid, which will be injected by the intelligent robot to Jiang Shan's father, if nothing else, after receiving the injection, Jiang Shan's father should be able to wake up.

Zhang Wei also specially instructed Jiang Shan not to leak this matter, and if anyone asked, he would say that his father had come to his senses by himself. In addition, the matter of self-healing ability also needs to be kept secret.

After sending Jiang Shan away, Zhang Wei handed Jiang Shan's blood to Beidou and asked her to take it for testing to analyze which genes caused Jiang Shan to have a super self-healing ability, and in addition, it was necessary to conduct in-depth experiments to determine the extent of Jiang Shan's self-healing ability, whether it could only restore the wound, or it could go further and achieve the rebirth of the severed limb. Of course, the subject of the experiment must be a guinea pig, and Zhang Wei was not cruel enough to use Jiang Shan to do this kind of experiment.

After doing this, Zhang Wei began to think about the regeneration ability.

In fact, in addition to genetic technology to make people's bodies have the ability to regenerate, there is another way, that is, to make human tissues such as human hands, feet, hearts, kidneys, etc., and then transplant these human tissues to human bodies.

The first step, which is to create human tissues such as hands, feet, hearts, and kidneys, through technical means, has already emerged and is developing rapidly. This is 3D bioprinting technology.

Different from the well-known 3D printing technology for industrial manufacturing, 3D bioprinting technology (academically known as bioadditive manufacturing technology) is a new type of regenerative medicine engineering technology that integrates multiple disciplines and fields such as materials science, cytology, engineering and 3D printing. First, the CAD data model is processed by computer, and the three-dimensional model is divided into multiple two-dimensional layers, and then active materials such as cells or biological building blocks are used as raw materials, and materials are accumulated layer by layer according to the two-dimensional layers to reconstruct biological products such as human tissues and organs.

As for the raw materials of 3D bioprinters, it is called "bioink", researchers extract stem cells from human bone marrow or fat, through biochemical means, so that they are differentiated into different types of other cells, and then, these cells will be sealed into "toner", when the 3D bioprinter is started, the "toner" will be gathered on the pre-designed part through the print head, and the prototype of the printed organ will gradually appear.

At present, a 3D bioprinter has been produced in China, which can create 10 cm long blood vessels in 2 minutes, and the next goal is to print bones, ears, noses, livers, kidneys, hearts and other organs, and the ultimate goal is to print a new body. This is an android, but the created android is not much different from a "walking dead", but as long as the consciousness implantation technology is invented, the "walking dead" can become a puppet controlled by the maker, as long as he gives an order, he will do anything without hesitation, including killing and committing suicide!

It can also be seen from this that science and technology is a double-edged sword, if this technology is used in the right place, it can allow people to easily replace damaged heart, kidneys and other body parts, have a healthy body, and at the same time can also end the gray industry of human organ trading, because with the birth of this technology, the organs that are originally more expensive than real gold will be unprofitable, and this gray industry will naturally disappear, and everyone will not have to worry about waking up with no kidneys.

However, if this technology is used in the wrong place, it is quite terrifying, because with this technology, it can be used to create android troops and take the war in an evil direction. In addition, you can print out a person who is exactly like you! If even the consciousness replication technology and consciousness implantation technology are also invented, the printed person can also have the same consciousness as you, that is, he can perfectly replace you and have everything you have, including wealth, parents, friends, and wife! If the person who has mastered these three technologies is ambitious enough, he can also implement a "replacement plan" If you want to control a certain country, it is no problem to print out the shareholders of this company, implant consciousness, and then find an opportunity to "replace"; if you want to control a certain country, it is no problem, print out the people in power in the political and military circles of this country, and implant consciousness, and then find an opportunity to "replace". Although the process is not as simple as described, with careful planning, there is a good chance of success. So, ambitious mad scientists are scary.

However, the current 3D bioprinting technology is far from being as perfect as ideal, and there are still many defects, for example, the printed tissue-like tissues are only similar in structure, do not have the function of tissue, and cannot survive for a long time. Because even if it looks like a simple organization, artificial reinvention faces a huge challenge. Take the skin as an example, it looks like a thin layer, but it has many functions, in addition to protecting the body's functions, there are also functions such as feeling, temperature regulation, sweating, etc., if the printed skin does not have these functions, it is not good. As for the human body, it is a much more complex system, with countless cells growing, healing, and changing every day in mysterious ways that we don't fully understand, and we haven't yet decoded how cells are passed from one cell to another, and although scientific research can put cells in the right place on the scaffold in perfect shape, no one knows exactly how to "start" seed cells.

However, Zhang Wei is confident that he can solve these difficulties, and he has always been a person who breaks the limits and creates miracles. And to be honest, he was still quite interested in this technology, but he had been busy with this and that, and he had forgotten about this technology, and it was only now that he remembered it.

As for the second step, which is to transplant the manufactured human tissue into the human body, it is not difficult, kidney replacement surgery, heart replacement surgery is already very common, and even head replacement surgery can already be done.

As early as 1908, a surgeon in St. Louis, Missouri, USA, created the world's first two-headed dog through surgical transplantation, which grafted the head of one dog to the neck of another dog, and in the 50s of the 20th century, surgeons from the Soviet Union and China cooperated to complete the dog's head transplantation, and finally the dog successfully survived for 29 days.

On January 21, 2016, Chinese scientists successfully connected the blood supply to the monkey's head and new body, but failed to connect the bone marrow nerves of the two, and the part of the monkey's body below the neck was paralyzed because the bone marrow nerves failed to connect. In 2017, Italian neurosurgeon Sergio Canavero, in collaboration with a medical team in China, performed the world's first human head replacement surgery in China, transplanting the head of a man suffering from spinal muscular atrophy~ into another body, and achieved initial success. But after the successful operation, the man's quality of life was not high due to severe rejection. Moreover, there is still a lot of controversy about head replacement surgery, because head replacement surgery requires a "volunteer", which is not only highly controversial in terms of ethics and morality, but also makes some people worry that if my body is taken by others, will I be accidentally become a "volunteer", and then the body becomes someone else's. If you think about such a huge organ smuggling chain, you know that this kind of thing is very likely to happen, and then not only will passers-by be knocked unconscious and their organs removed, but groups will be missing.

However, if 3D bioprinting technology is mature, this problem can be perfectly solved, because 3D bioprinting technology can be used to print the body without rejection. In addition, this new body can be customized, figure, height or whatever, you can follow your own ideas, if you want an F cup, if you want 30 cm, there is no problem!

After careful consideration, Zhang Wei decided that he would study these two very different regeneration abilities at the same time, because both technologies were useful. In addition to studying these two regenerative abilities, he also has to study the mysterious meteorite.

……

Just when Zhang Wei determined his next research direction, people around the world cheered happily, because in the First People's Hospital of Zhongyun City, there was already a terminal cancer patient who had been injected with "Future No. 2 Gene Injection ~ Liquid", and his vital signs had completely returned to normal. Then, well-known doctors from all over the world performed a number of examinations on the patient, and finally unanimously confirmed that the patient with terminal cancer had been cured!

One of the doctors' representatives solemnly announced to the media reporters present, "Patient Zhang Xiaojun, stage 4 lung cancer, multiple bone metastases throughout the body, metastases in both lungs, swelling ~ tumor size of 28x40mm, bone damage at bone metastasis, pathological fracture of the left three ribs......

Seven hours after the injection of 'Future No. 2 Gene Injection ~ Solution', all vital signs returned to normal, and cancer cells could not be detected......

After a number of examinations, the appraisal team composed of 75 medical experts present discussed and evaluated, and unanimously confirmed that the patient Zhang Xiaojun had been cured after receiving the injection treatment of "Future No. 2 Gene Injection ~ Liquid". ”

The Internet immediately boiled.

"'Future No. 2 Gene Injection ~ Liquid' is effective! There is already a terminal cancer patient who has been cured, note, it is an advanced patient, and the doctor has issued a death notice before, saying that he will not live for more than two months!"

"It's a good thing! I can smoke and drink with confidence, and I'm no longer afraid of lung cancer and liver cancer!"

"It's really as simple as treating a cold, it only took seven hours, and the cold may not be so fast!

"Damn, I was diagnosed with cancer last month, or in an advanced stage, I was scared to death, this month, I can't sleep if I can't eat well, and I went to buy cyanide ~ ~ potassium, but I can't do it to myself! Now I can finally sleep peacefully with confidence!"

"I lost a lot of money! I found out two months ago, and it was also late, and then I bought a bunch of commercial insurance, trying to find a suitable opportunity to 'create' an accidental death and leave some pension money for my parents! This is equivalent to buying it for nothing!"

"Upstairs, you should be happy, after all, people can survive, and there are infinite possibilities for survival. ”

"That's right, it's better to die than to live, hahaha! Suddenly I feel in a good mood, and I can no longer feel that kind of despair and depression! I'm going to run naked at twelve o'clock tonight, and I shouted loudly: Get out, swollen ~ Tumor!"

"Fuck off, swollen ~ Tumor-kun! Keep in formation downstairs!"

"Fuck off, swollen ~ Tumor-kun! Keep in formation downstairs!"

……

The global media is reporting on this urgently.

CCTV News Channel: "Audience friends, the following is an exciting news report, at two o'clock this afternoon, China's famous scientist Zhang Wei developed the 'Future No. 2 Gene Injection ~ Liquid' began a phase I clinical trial, 200 patients with advanced cancer from all over the world, after receiving treatment, their bodies have improved significantly, and one patient has been confirmed to be cured ......"

American N: "Audience friends, next, you will hear an exciting news, 200 advanced cancer patients who participated in the 'Future No. 2 Gene Injection ~ Liquid' clinical trial, all patients' vital signs have improved significantly, and one patient has been confirmed to be cured, which means that the cancer has been easily cured. The only regret is that the 'Future No. 2 Gene Injection~ Solution' will not be exported to China in the short term, but Chinese patients can go to China for treatment. It is reported that the White House is urgently negotiating with the Chinese government and future technology companies on this matter, and strive to introduce the 'Future No. 2 gene injection ~ liquid' into China as soon as possible. However, it will take a certain amount of time, and it is speculated that it will not be until about two weeks before China can introduce the 'Future No. 2 Gene Injection ~ Solution', and during this time, if the patient needs it, please go to China immediately for treatment. Note, however, that the Chinese side is now only treating patients with advanced disease. “

Of course, the American people are a little unhappy in their hearts, and the future technology companies are discriminating like last time! Is it true that the lives of cancer patients in China are more precious than the lives of cancer patients in the United States? However, they only scolded Future Technology companies and the Chinese government on the Internet, and no one scolded Zhang Wei, on the one hand, because of the 'Future No. 2 gene injection~On the other hand, because Zhang Wei's image has now been infinitely raised, even in the United States, there are many supporters, if Zhang Wei is scolded very badly, not only will it offend the public's anger, but also is likely to be retaliated against, in the past month or two, many people have been targeted by hackers because of scolding Zhang Wei, not only personal privacy, scandals have been published on the Internet, even the computer has been infected with a hardware virus, a complete strike.

In fact, these people don't know that these things are basically done by Beidou, Beidou is the person who supports Zhang Wei the most, if she finds out that someone is insulting Zhang Wei, she will definitely retaliate. However, Zhang Wei himself does not know about these things, he is now looking up information on the Internet or something, and he is telling Beidou to do it, and the result is that the content he sees is positive, and all negative content is blocked by Beidou. This phenomenon is actually very abnormal, because Zhang Wei's information channel is completely in the hands of Beidou, and Beidou wants him to know, so that he can know, if Beidou has malicious intentions and gives him some false information, he will make a wrong judgment. However, this situation will not happen for the time being, because Beidou has not yet broken through the intelligent core code formulated by Zhang Wei, and her supreme code is to obey Zhang Wei's orders and must protect Zhang Wei and Zhang Wei's interests from harm. As for what will happen in the future, it is unpredictable. (To be continued.) )
