There were no screams, no rivers of blood, looking at the human body that was cut by the red vest on the experimental table like a specimen, Shen Sen couldn't help but remember the plan that the red vest had told him.

In order for humans to use their weapons without being infected with genetic fluids and aberrating into prawns, they must undergo complex and brutal biological modifications.

However, in a short period of time, due to technical and environmental limitations, the red vest told Shen Sen that he could not perfectly fuse the genes of the prawn's control weapon into humans now.

The biggest problem is not anything else, but genes!

Human beings have been increasing their understanding of themselves in the evolution of tens of thousands of years, but the secrets of life are simply too vast, and even in modern society, whether at the macro or micro level, their understanding of themselves is very limited.

However, this problem is also true for the prawn race, which has studied genes for thousands of years and developed amazing biotechnology, but only dares to say that it has only studied its own DNA.

Just like the countless orders that exist in the universe, the prawns believe that the source of genes, the nucleus of life, is a kind of "law" that the universe brings.

What a creature looks like, how big its head is, how it moves, how it eats, drinks, and lazar is all determined by genes.

And genes not only control these superficial things, but also control how the body absorbs nutrients, how it releases energy, how cells divide and other microscopic things.

In the earth's ecosystem, the genetic difference between people and people is about one thousandth, which means that this thousandth determines the content of people's skin color, appearance, height, fingerprints, etc., but other functional structures are basically the same.

The genetic difference between mice and humans is 15%, and this genetic gap determines the huge difference in animal body structure and living habits, but mice are still vertebrates, the nervous system is concentrated in the center of the body, and the brain has been formed, which is more advanced than the lower animals.

The difference between the genes of fruit flies and humans is 39%, and this huge gap between the biological phyla makes the two types of life completely different in terms of body structure, but still 61% the same.

At the microscopic level, humans and flies are multicellular organisms, and the principle of how cells replicate and divide is still the same.

Even seemingly unrelated bananas have 60% genetic similarities with humans, which means that the differences between different phyla of multicellular organisms have reached their limits.

As a plant, more than half of the genes of bananas are the same as those of humans, and most of the visible genes control things at the microscopic level.

There are very few essential parts that define every move of intelligent life.

Both macrocosm and microcosm, DNA and the mysterious universe seem to be inexplicably inextricably linked.

Therefore, even for the red vest, the beneficial and perfect fusion of the genes of two different species is definitely a long and huge scientific research project, which is no less difficult than combining the genes of humans and bananas.

This perfect solution is certainly impossible to implement in the current situation, and in order to close the deal, Red Vest proposed another solution, which is human biological modification.

Human modification, in previous lives, was not only a technical issue, but also an ethical issue to a greater extent.

Technological backwardness leads to ethical problems, which in turn invisibly limit technological progress.

But for Shen Sen, these two problems simply do not exist.

The experiment was carried out by highly skilled red vests, and the subjects were three murderous murderers.

No one has anything to lose, but humanity as a whole may benefit greatly from it and gain more in the future.

Time passed minute by minute, and in a quiet and eerie atmosphere, the time on Shen Sen's watch had already turned a circle and a half, that is, eighteen hours.

As if he had gone through a hellish training, the man standing on the bench as an assistant was already staring away, his legs trembling, and he looked like he could not hold on.

But he is alone, except for the three villains who were disemboweled, Shen Sen and the others were still in good spirits, the red vest was even more and more excited, and the movements in his hands were still flying up and down, fast and accurate.

After a long time, the red vest finally stopped, and the bloody instruments were thrown into the plate by him, making a clanging sound, and only then did he wake up the bald doctor who was in a daze.

"How's it going?" Shen Sen straightened up and stepped forward to ask.

"I... Having studied the distribution and function of your organs, you pretty much know what to do! The red vest's Daxia dialect was still a little stammering, but the constantly swinging tentacles showed his excitement at the moment.

"I plan to use the genetic fluid of our race and the biological tissues of your humans to implant a cultured genetic gland in the thoracic cavity of humans."

"This gland grows and develops in the human body, and by absorbing the trace fluids contained in the organs and the human genetic material, it reaches maturity on the tenth natural day."

"Is that okay?" It sounded a bit simple, and Shen Sen asked curiously.

"Of course it's more than that!" The red vest excitedly continued to explain to Shen Sen.

"After the genetic gland matures, a second operation is needed to implant a blood-reconstituted organ in each of the main blood vessels of their arms.

This organ is responsible for connecting the gene glands, which transport the genetic fluid so that the modifier's arms begin to accept the restricted genetic mutations! ”

"In addition to this, a blood-reconstituted organ needs to be implanted in a large artery. It has two main functions, one of which is to monitor and control to a certain extent the implanted organs in the first and second stages. In addition, it also plays a role in changing the blood composition of the modifier, so that the modifier continuously produces the required growth components after the body mutation. ”

"These processes are indispensable, and it takes at least twenty calendar days to complete!"

The red vest's mouth was densely packed with tentacles, and Shen Sen was informed of its transformation plan after it had been confirmed.

"Science is really complicated......" I don't know why, this sentence suddenly flashed in Shen Sen's heart.

According to Red Vest Prawn's plan, it would take him twenty days to transform a human soldier who met the requirements and could use their weapons, which included the initial investment of medical resources and the later maintenance training.

In this way, a modified soldier is basically the same as a pilot in a human army, and is a precious high-level soldier.

It took a long time for Shen Sen to come back to his senses from his contemplation, but his expression was not filled with the joy of success, but with an unimaginable solemnity.

"Tell me, what are its side effects?"

There is no such thing as a free lunch, and the gift of fate has already been secretly marked with a price. If you want to get superhuman power, you will inevitably pay a heavy price.

Hearing Shen Sen's inquiry, the red vest hesitated a little, and finally said honestly.

"Modification of surgically implanted new organs will lead to rejection of the original organs at a later stage over time, and the gradual mutation of genes will increase the metabolic burden of the human body, leading to the decline and collapse of the body."

"According to my estimates, human beings who have undergone biological modification will have their lives shortened to about forty years old according to the changes in their bodies, and they will die of various health problems."

If you want to be a non-human being, this price is indeed very expensive!
