A small box that is quite heavy, and after opening it, a cold air hits the face, which is a cryopreserved black light virus. A D-level side plot, 5000 reward points, the ratio of the two resources is quite different, and the proportion of side plots and reward points has suddenly increased, and now Zhang Haolin only has a few hundred reward points and a bunch of side plots left. It suddenly occurred to him that the items related to technology seemed to have very low requirements for the side story, while the Legends of Magic items were the opposite...... Wen Yu exchanged for some props and accessories that can slightly increase mental abilities, all of which are a few hundred small reward points, but each must pay a D-level side story.

Maybe in the future, the consumption of these side plots will have to rely on the exchange of legendary props.

Although it is "not cost-effective", the reward points required for this virus obviously cannot be saved, and the black light virus is carefully removed from the refrigerator, and a small injection of less than a milliliter of transparent colorless liquid stays in the thin needle tube, and it is completely impossible to see that it is a terrifying biochemical product that can easily turn ordinary people into monsters.

Weng Wei's enhancement had been completed quickly, and watching Zhang Haolin take the virus out of the box, he couldn't help but speak: "Can you inject two people, or cultivate it yourself, and you can save these 5,000 reward points in the future." ”

"The description is written for one person, don't risk trying, as for cultivating yourself, let's wait until our team has medical experts." Zhang Haolin put down the instructions, took off the protective cap of the injection tube, and prepared to wait for the injection to rise to room temperature for injection: "Ani, stretch out your arm." ”

The little warrior, who had always behaved obediently and fearlessly, suddenly showed a frightened expression, although the syringe of the virus did not hold a shiny, slender sharp needle like the normal model, but she had an inexplicable fear of being injected - her short and tragic childhood all began with an injection of giant potions.

Subconsciously hid her arm behind her back, she didn't dare to stretch it out for a while, Zhang Haolin had to reach behind her back and hold her hand and pull her arm out: "Either now, or tomorrow or the day after tomorrow." You can also choose for yourself. But things have changed, and you can't hide from them. ”

"Well—now then." In the end, reason overcame the subconscious fear, and Ani obediently let the other party grab his arm, folded his sleeves, and revealed Bai Shengsheng's arm.

"The instructions say that there are four outcomes of the injection. The first is that the body is controlled by the virus and turns into a monster. The second is that the body and the virus are in a stalemate with each other, becoming the 'adaptor', that is, the existence of the protagonist in the killing city, although it has also gained strong change ability and combat effectiveness, but the virus and immune cells are always fighting in the body, making the human body in constant internal friction, and need to constantly eat and even kill to replenish the ability. The third is the outcome we want. The body defeated the virus and absorbed the adaptive gene fragments in it, making it possible to strengthen the multi-bloodline. The fourth is when the cell viability is exceeded, and the body destroys the virus in a very short time, causing it to be completely ineffective. ”

Weng Wei nodded thoughtfully: "So, the first and fourth situations are complete failures, and the middle two are considered successful?" ”

"Yes, but we want the third outcome. Because the second result, although it increased its combat effectiveness, only turned Arnie into a pure physical melee that was much stronger than ordinary people. If you want to develop, you have to kill and devour other virus infected, not only is the means disgusting, but you also get a very strong melee bloodline, although it may be the most expensive D evaluation enhancement, but it is scum in the late game. The most critical thing is that in this case. Ani will be reproductively isolated from ordinary humans, and may even conflict with the original giant transformation, which is technically a failure. ”

"Reproductive isolation, doesn't that mean that this reinforcement will make her a non-human? That in addition to retaining consciousness. It's no different from a monster! Wen Yu glanced at Ani, imagining the scene of this little girl becoming an adaptor, changing her body and devouring others, and couldn't help but shiver: "This thing is so dangerous, do you really want to use it." ”

"As long as it's not the third case, if there is any accident, we will directly let the Lord God clear all viruses." Zhang Haolin held Ani's thin arm and picked up the syringe: "I have already inquired, the Lord God provides this service." ”

With that, he stopped talking nonsense and pressed the syringe to Arnie's arm.

The syringe is injected without a needle, and the pain is quite weak, as if it was bounced by a small stone, and the small injection of liquid has been injected under Ani's skin.

Quickly returning the used syringe to the cooler and handing it to the Lord God to destroy, the crowd began to surround Ani to observe her condition.

――

Zhang Haolin let go of Ani's arm, and on the little girl's milky white skin, a small red mark was fading rapidly...... On the outside, there seems to be nothing abnormal, but under the skin, an epic battle at the microscopic level has begun, and the two sides are: the black light virus produced by the 10 billion main god VS the immune system of the vitality of Ani 390 cells.

The first defensive battle, is the virus before reaching the cell, encountered a huge amount of antibodies floating between cells, because the virus is injected into the skin, so the outer layer of the human body defense has been bypassed, these antibodies are the last line of defense before the virus reaches the cell, if it is a known virus, these antibodies will be tightly adsorbed on its surface at the moment of contact with the virus, wrapping it into a ball, so that they and other viruses around them stick together to form a mass that hinders their invasion, after the target becomes larger, The virus is also more likely to reach white blood cells and be devoured by this huge defender that roams between cells.

The cell vitality of 390 is more than three times that of ordinary people, and the action of white blood cells in Ani's body is much stronger than that of ordinary people, and any virus that comes into contact with white blood cells is captured and destroyed in an instant, even the famous black light virus is completely unable to resist this kind of perverted immune cells.

Unfortunately, the black light virus is a new foreign virus to Ani's immune system, and antibodies are completely unable to recognize such targets, and the first line of defense is useless. With the exception of a small number of unlucky black light invaders who crashed into the arms of white blood cells, 99% of the viruses successfully reached the surface of the cells they needed to attack.

In the first battle, the black light virus won completely.

The second attack and defense takes place on the surface of the cell. Unless the probe outside the phospholipid bilayer confirms that the visitor is on the "access list", any macromolecular foreign matter will be blocked in this layer. Despite its reputation, the black light virus is still a virus in the traditional sense rather than a virus-sized destructive machine. It's too small even for cells...... It is not possible to burrow into cells as the general public thinks, nor can it cut through cell membranes like large and robust bacteria.

However, in billions of years of competition, viruses have long evolved special ways of entering cells - they carry fake access permits on their surface tentacles, which can fool the gatekeepers on the cell membrane. Let the cell membranes open the channels and let them drive straight into the ...... This process of deformation is called "endocytosis".

A specific virus can only infect a specific organism, and this is because it is difficult for a virus to carry enough information to fool the cell guardians of non-host organisms, but the artificially cultivated black light virus targeting humans is obviously an expert in fooling human cells, and in this way, the virus army once again drove straight into the cell.

In the second battle, the black light virus won again.

The third offense and defense are already in the cell. The basic building blocks of living things are not defenseless against viruses. This is especially true of Ani's cells, where there are structures called endosomes that capture macromolecules, including viruses, that are swallowed by the cells and break them down into various raw materials needed by the cells in a highly acidic environment......

This level treats all outsiders equally, and the black light virus can no longer be fooled, and a tragic war begins, with a large number of viruses being broken into pieces in the endosomes. In addition, a large number of viruses rely on the destructive chemicals prepared under the outer shell to corrode the inner and outer walls of the nucleus, rushing out of them and rushing to the nucleus...... The black light virus is five or six times more damaging to endosomes than the common cold virus, but the ani cell viability is as high as 390. Most of the structures in the cell are more than ten times stronger than ordinary people, and the first hard-fought defensive battle in this cell has finally achieved results, 99.9% of the black light virus has been eliminated at this stage, and only a few lucky ones have successfully penetrated the outer wall of the inner and outer body of the nucleus under the cover of friendly forces and regained their freedom.

In the third battle, the defensive line was broken down after a bloody battle. But the vast majority of the virus has been wiped out, and only the last force remains, smashing the yellow dragon and rushing to the nucleus.

Within the Great Wall, there was no large-scale resistance. But the fourth defense comes from the strategic depth inside the cell – even though the virus is only a few tenths of a micron away from the nucleus at this time, proportionally. It wants to reach and occupy the nucleus, just as a blind man wants to march accurately from Bohai Bay to Beijing and capture it without navigational equipment, unable to distinguish directions, unable to know the way and unable to ask for directions, and the most difficult thing is that the person is also physically disabled - the virus itself is not very mobile, and the mitochondria in the cell do not provide energy to it.

It's an almost impossible task, so the virus needs help. Once again, it uses its ability to disguise deception: using a forged pass to fool the cell's porter, dynein, into believing that the virus is a macromolecular protein needed for some kind of nucleus, so that it binds to it and carries them deeper into the cell.

If it is the body's self-defense army that fights the virus, then these dyneins are the workers who build the body. The high viability of the cells only made these "workers" stronger, but the non-defensive units could not recognize the virus, and with the help of these stupid workers, the invaders once again embarked on the journey to the nucleus.

The structure of the human body is far more delicate than ordinary people think, most of the cells themselves are a complete living system, with the help of dynein, the viruses cling to the microtubules in the cells, and smoothly approach the nucleus along the logistics routes within these cells, but by this step, at least the cell has not lost its ability to resist - the fifth line of defense is distributed on both sides of the road in these cells, and there are some special proteins on the side of these microtubules, and their task is to monitor all the large protein molecules that pass byIf an anomaly is detected, such as a small number of antibodies adhering to the surface, or an abnormality in size and shape, they will adhere tightly to the surface of the virus, marking the enemy's position to the last defending army and sending out a "fire at me" signal.

The last defense army, the recovery tissues known as the proteasomes, will immediately arrive at the scene and begin to break down this "abnormal large protein molecule", the virus.

This level is the same as the defense line of the endosome, because the nucleus cannot use any undecomposed large proteins, so the decomposition of the proteasome to the target is also indiscriminate between friend and foe, as long as the abnormality is completely destroyed, here, the virus is tested again, this time their opponent is smaller than the virus itself, the black light viruses can not resist any resistance except relying on the strength of the structure to resist decomposition, except for a few fish that have slipped through the net, 99% of the viruses that have broken through the endosomal defense line to reach here are once again stopped by this last level, It is broken down into small camp-free proteins.

――

It takes a lot of manpower and material resources to subvert a country, and similarly, it takes a lot of viruses to infect a cell, but in the end, as long as one reaches the nucleus, they win the battle.

Less than 1 in 100,000 viruses eventually reach the nucleus, but the viruses rely on a huge base to capture a large number of cells, and they face the final test - the nuclear membrane is very thick and does not endocytosis, only the nuclear pore on it can be used to enter and exit, but the nuclear pore is used to receive small molecule proteins or chemical pheromones, and although the virus can fool the nucleus into accepting itself, it is too large to enter......

Ordinary viruses may have to toss around here for a while, but the black light viruses easily break this last layer of protection - they dissolve their outer shells outside the nucleus, releasing what is vital to this war - viral DNA.

The nucleus is the control center of the cell, storing the blueprint of the human body, that is, the human DNA, it always pays attention to the instructions of the human body, what protein the human body needs, and the biological machine in the nucleus will retrieve the raw materials and synthesis methods needed to produce this protein from the long DNA chain, and transmit the information to other parts of the cell, so that the protein factory can produce these proteins for the human body.

……

Just like dynein, all the structures in the nucleus are "workers", they can't tell the difference between human DNA and viral DNA, which is actually normal, all organisms have a main line, so the DNA structure of different organisms is exactly the same, just like a piece of code, you don't fully understand or even run them, you won't know if the code is malicious or a normal program...... The nucleus of the cell takes the viral DNA as a message from the human body and quickly begins to function.
