Chromosomes are objects with genetic properties in cells, which are easily dyed dark by basic dyes, so they are called chromosomes or chromatin. Its essence is deoxynucleotide, which is a structured thread body composed of nuclear proteins in the nucleus, which can be stained with basic dyes, and is the carrier of genetic material gene DNA. In layman's terms, the filaments of the double helix structure of DNA are entangled like a ball of yarn to form a strip of yarn, and this ball of yarn is the chromosome.

Regarding the 24th pair of chromosomes, it is actually a strange creep found in the 52nd Military Region, a bit like a parasitic organism. Because it is exposed to the outside world on its own, it forms a thin film that wraps its own chromosomes into a dormant state, that is, the jellyfish-like creature. When it encounters a parasitic target, it will burrow into the target's body, burrow into the cells, use cell nutrition to divide rapidly, and gradually implant all cells in the target body into the Z chromosome.

However, parasitism usually refers to the fact that one organism inhabits another organism and absorbs the nutrients of the parasitic organism to survive. The Z chromosome, on the other hand, is not, and it is more appropriate to call it fusion than parasitism. After the Z chromosome is integrated into each cell of the host, the genes in the Z chromosome will be gradually expressed to improve the host's ability. As long as the host does not die, the Z chromosome will not leave the host's body, which is a new type of life.

The genes stored on the Z chromosome are gradually expressed, a process that can be called second development. Ordinary human beings go through many stages of development from embryo to maturity, and these processes are actually gene expression processes.

Gene expression refers to the transcription and translation of genetic information stored in DNA sequences into biologically active protein molecules during the life of cells.

Human beings develop from a cell to a mature individual, during which they grow organs such as hands and feet, heart and lungs, which are the results of differential gene expression, the essence of which is to open certain genes in different cells and close certain genes, resulting in cell differentiation, the emergence of cells with different utilities, and the same cells are gathered together to form organs.

In the whole process of human development, the number of genes expressed accounts for about 5%~10% of the total number of genes. Most of the rest are recessive genes and non-expressed genes.

After human development and maturity, various cells have been differentiated, the switch of gene expression has been fixed, and there will be no differential changes under normal circumstances. However, after the Z chromosome enters the human body, it does not remain silent forever, and it begins to express the genes stored in the Z chromosome within the host's tolerance range.

The development process of this gene expression usually disrupts the originally stable gene expression switch in the host, and it is very likely that abnormal development will occur, and the final result is determined by the interaction between the Z chromosome and the host gene, and the result is difficult to predict.

In the previous life, the Z chromosome was discovered by the introduction area, but it was not fully interpreted, and then it disappeared mysteriously, and it is estimated that it was taken away by Du Pu. It's just that after he was reborn, it seemed to change the course of things.151 The Academy of Military Sciences of the Military Region and Dulong Pharmaceutical Laboratory have not yet reached any conclusion on the research of the Z chromosome, and the Z chromosome was stolen by Du Pu. It is estimated that his own appearance stimulated Du Pu and made him take the Z chromosome in advance.

As for the "inheritance of God" mentioned by Z Du Pu in front of him, it is obviously a kind of praise for the Z chromosome, and the gene is originally a kind of inheritance carrier, if this inheritance is strong enough to a certain extent, it is okay to call it "the inheritance of God".

Before his rebirth, Du Fei didn't know much about the Z chromosome, after all, these were all confidential laboratory materials, and only some superficial content was circulated. Therefore, Du Fei's cognition of the Z chromosome is limited to knowing what it is and what its specific function is.

However, now Du Fei guesses that this Z chromosome should be a special evolutionary body, and in the process of evolution, it has evolved into a parasitic fusion special evolutionary body without finding excellent combat genes.

Thinking of the 24th pair of chromosomes, Du Fei's heart flashed with inspiration, and he suddenly felt that the bloodline medicine exchanged by the exchange system was very likely to be a chromosome or a DNA strand connected to the genes of human cells. It is through the expression of the bloodline gene that the bloodline shows the external form of the bloodline.

Du Fei once thought about using the bloodline elixir to do an experiment, and then copy a large group of bloodline warriors, but once the exchanged elixir is opened, it must be used immediately, otherwise it will decompose and dissolve by itself in ten minutes, and it will not be able to be stored at all. It is also too difficult to replicate the bloodline potion by using the user's body cells, not to mention the need to find a technology to disperse genes into human cells, which is not something that can be done in a short period of time. ,

Z Du Pu just said a word, Du Fei thought of so many things, but in fact, it was just a matter of a moment.

After figuring out the current state of Z Du Pu, Du Fei became murderous, if this humanoid monster with unknown potential wants to stay flat, it will definitely be a big trouble in the future.

Du Fei's momentum suddenly became fierce, and Z Du Pu also felt it, revealing a cold calm smile and said~~ "Are you ready to fight?" 、……

"That's right, you don't belong to the category of humans anymore, so it is necessary to remove this hidden danger from you." Du Fei pulled out the "Wind Sword" and said unhurriedly.

"Well, anyway, I still have hatred for you in my heart, and I can be much happier to kill you. Of course, I'm sure your taste will please me. Z Du Pu slowly got up from the chair and said.

As he stood up, the floor of the garage began to shake slightly, and thick glass walls rose from the ground, gradually enclosing the entire garage, slowly forming a crystal palace-like space.

Du Fei frowned slightly, making glass is Du Pu's own source ability, but with this strength now, it has definitely reached the strength of level 4 source ability. I'm not afraid of Level 4 evolutions, but it's not a good idea to fight a glass controller in a confined space that is all glass on all sides.

Du Fei took advantage of the fact that the glass wall was not completely closed, and carried the "Wind Sword" and rushed to a gap with his body technique.

Z Du Pu shook his hands, and two glass bloodletting thorns appeared in his hands, and then rushed towards Du Fei at a very fast speed, aiming at Du Fei who was running, and threw out the glass thorns with all his might.

The speed of the glass spike is extremely fast, and the attack is accurate and ruthless. It was a little difficult to block it with the metal layer on the surface of his body, so Du Fei had to turn around and swing his sword to block the glass thorns.

Z Du Pu took the opportunity to quickly close the glass wall, and at the same time, two more glass blades appeared with both hands, and he slashed them with a wave of the blades, and said, "It's better to stay." I've heard that you're strong, let's have a good fight, let me see what you're capable of. If it's really that strong, God Z may choose you as the new successor. ”

"The chaotic genes that are randomly cobbled together can also claim to be gods, and the arrogance of the evolved body is really innate, which is really ridiculous." Du Fei said as he swung his sword to block the slashed glass blade, stepped on his feet, and performed the Drunken Immortal Moon Step to leap towards the roof at a speed as fast as a strong wind.

The roof of the garage is made of iron sheets, and now the four fronts of the garage have been sealed with thick fiberglass walls, only the roof has not been sealed. Du Fei always felt that there was another creature peeping nearby, so he couldn't throw all the pupil techniques on Z Du Pu, and decided to leave this place first.

Z Du Pu had long expected that Du Fei would break through from above, and as soon as his palms were closed, the four walls stretched out to show the glass maniac, like a transparent arm grabbing it.

Du Fei swung his sword to cut off the two glass arms, and released the metal to block the rest, and his feet continued to slam on the void, continuing to rush upward, and he was about to break through the iron roof and leave the garage.

Seeing this, Z Du Pu shouted loudly into the void: "Demon Queen, don't make a move?" ”

"Ahaha......" A familiar sultry laugh sounded, and then a very seductive female voice said, "Here, what are you urging?" ”

Du Fei's brows furrowed again, this sultry laugh was made by the half-makeup woman he saw after Zhisu killed the humanoid monitor lizard evolution. Du Fei glanced around, but found no trace of any woman.

And the tin roof was in front of him, so he decisively decided to rush out first. With a wave of his hand, he unleashed his source ability to melt the iron sheet into a hole, and then his body rushed towards the breach.

But just before Du Fei was about to pass through this source ability and open the dog's gap, a wave of subtle distortions suddenly occurred in the void near the breach, just a slight little distortion, and if it was a level 3 awakened person, he wouldn't be able to find it at all.

Du Fei didn't have time to hesitate, covered the surface of his body with a large amount of metal, and then went straight into the break. Middle. It's just that after passing through the breach, I don't see the sky outside, but I feel that it is dark in front of me.

Just after Du Fei passed through the breach with void fluctuations, a similar fluctuation occurred on the ground of the garage, and then Du Fei drilled out of the ground. But the tiles on the ground are still intact, and if you think about it with common sense, you can't understand how it came out of the ground.

Du Fei's eyes were dark, and when he saw the things around him clearly, he was surprised to find that he was back on the floor of the garage.

Z Du Pu showed such a cold smile, held his head high and said: "You can't run away, today you are destined to become a part of our body." ”

As soon as Z Du Pu's words fell, another sultry laugh sounded, and the half-makeup woman who was called the enchantress by Z Du Pu gradually appeared behind him. is still dressed like that, half of his body is almost naked, his skin is white and round, sexy and sultry. On the other side, she was dressed dignified and gorgeous, without revealing any skin, and even the side of her face was covered by purple black hair, which made people wonder if there was a monster hiding on that half of her face.

"Z chromosome, you really walked into the incarnation, the so-called dark awakened person is just your host." When Du Fei saw the hidden enemy, not only did he not feel the danger, but relaxed...... ）
