The emergence of genetic adjustment, a technology that is beyond the age pursued by mankind, will undoubtedly break the limits of carbon-based life and allow mankind to develop towards perfect life.

It may be a bit illusory to say this, but it is more practical to make humans healthier, more powerful, have the means to breathe without oxygen in outer space, and so on.

However, there are many ways to go if you really want to achieve your goals, and in order to achieve your goals, standing on the basis of existing science and technology, the closest thing is undoubtedly genetically modified technology - a technology that grafts the genes of other lives into the genes of another life to create new varieties.

As early as half a century ago, Cohen transferred the penicillin-resistant gene of Staphylococcus aureus to Escherichia coli, which opened the prelude to the application of transgenic technology.

Later, transgenic technology was applied to plants, animals, and microorganisms, including the well-known Monsanto company, which is famous for its genetically modified seeds, which have higher yields, insect resistance, and cold resistance, thus surpassing native plants.

Although there will be stability problems, and even genetic diseases, for Cao Chuan, this is bound to be a problem he wants to focus on, and it will not prevent him from exploring, at least, on the road of genetic adjustment, transgenic technology has a low threshold, and the effect has obvious predictability advantages, the reason why human transgenic technology has not been produced for so long, in his opinion, is a ridiculous moral constraint, restricting human beings from applying transgenic technology to the human level.

Think about it, if you don't start researching from this step, where exactly will genetic modification start? Move directly to the more difficult genetic modulation based on genetic design, or something else?

Dr. Charles assisted him in collecting the genetic samples of his employees, which would become the basic material for subsequent adjustments, and he examined the samples through the instrument, and then followed the genetic mapping data completed by humans 10 years ago to find the corresponding fragments of interest to him.

This stage was very smooth, and it took a day to extract the corresponding gene fragments, and Cao Chuan valued several fragments with special effects this time.

The first fragment is cold resistance, which manifests as skin tissue that has a heat-insulating effect, and humans who have lived in cold regions for generations usually have this gene fragment, which increases the temperature tolerance range of humans by more than 20 degrees Celsius.

The second segment is anaerobic respiration, which manifests itself as a way to work in the alveoli in environments with very low oxygen levels, even with nitrogen.

The third fragment is the anti-radiation, which is manifested as the addition of special check genes on the gene helix, even if it is mild radiation, if the gene mutation occurs during cell division, due to the interference of the check gene, the cell division process will be stopped, preventing further dangerous consequences.

The fourth segment is to strengthen the muscles of the stomach wall, and with the creation of a moderate acidic environment, it will increase the body's ability to digest food and special substances, and draw more sugar, water, minerals, and proteins from it.

The above four clips were selected by Cao Chuan, the most suitable for the Pluto battlefield, in such an environment, physical fitness is definitely not a priority, adapting to the environment is the first, it allows employees to play 100%, or even 150% combat effectiveness. At the same time, these gene fragments are samples that have been confirmed and studied and have practical value, and more mature technologies should be found to insert gene samples into the corresponding positions to ensure sufficient stability to achieve phased results in genetic adjustment.

Knowing what to do, there are still a lot of difficulties in the whole process, including precise insertion, ensuring the safety and stability of fragments, and spending time waiting for cell proliferation and replication, and then merging with the adjuster.

In the past, the above process may last for more than half a year, and with the relevant technology to stimulate cell division, the effect can be seen in a maximum of one month.

The following rule simulation, his goal is to find out how to solve those few problems, and another ten days have passed, and as the technology has evolved, the time spent on the scale simulation has grown.

Finally, he broke through the bottlenecks that he would encounter in the process, understood the whole process in his mind, and then made great strides and began to adjust.

First, the fragments are examined at the molecular level through a microscope to ensure that the fragments are independent and complete, and do not contain redundant genetic information.

This was followed by the reproduction of fragments, this time he had to concoct at least 101 people, if he didn't prepare the most primitive materials well, what could he do?

At this point, and even in the next step, it is necessary to use the tool enzyme that is often used in transgenesis, a special substance that meets the molecular mechanical definition to complete a variety of molecular-level operations.

For example, gene fragments are self-connected with the help of tool enzymes, and then continuously self-multiplied through nutrient solutions, so that hundreds or thousands of adjustment materials can be easily obtained.

The next step is to extract a gene sample from the nucleus of the modulator cell and use another tool enzyme to cut and block the gene fragment at the specified location.

The next step is simple, using the tool enzyme as a carrier to transport the sample to the corresponding position to complete the final replacement.

After three days of experiments, Cao Chuan finally got the first cell adjusted based on his cells, and it is only a skin cell, you know, all people in adulthood, the function of cells differentiates, so don't think about completing the replacement of fragments such as cold-resistant properties in a skin cell, and then continue to proliferate, so as to affect the entire body, so that your muscles, brain, eyeballs, and bones have the ability to resist cold.

This is clearly not something that can be done by this generation of genetic modification.

There are a total of 4 types of cells, which are placed in the culture chamber and continue to proliferate, divide into more cells with similar functions, or even transform into pieces of tissue, and at this point, the number of each cell exceeds 1 million, which is a considerable number, and it is time to actually perform the operation.

The goal of surgery is to allow the adjusted cells to replace the outdated cells and work in the body.

The process is first injected, the formulated cells will be sent to the body location, such as the skin, still using the activation liquid stimulated by cell division, to accelerate the division of these cells, because the human body has its own balance, the rapid growth of cells will never become something messy, in the process, will be replaced little by little.

The adjustment is slow, but the effect is obvious, and with the cooperation of Dr. Charr, Cao Chuan has completed 4 genetic adjustments one after another, and he is checking the number of new cells in the body every day to check the changes in the body.

The moon is a pretty good place to run out from time to time, and if genetic modification has an effect, it will definitely be noticeable when wearing some light protective clothing.
