It's okay, I've been a little bit less resistant lately, I catch a cold at every turn, there is air conditioning in the department, I'm comfortable wearing long sleeves" Zhang Qiao smiled shyly, a little embarrassed by such concern.

"Then you have to pay attention, is your body too weak, eat more wolfberry mutton to supplement, how can your body be like this when you are young." Looking at his colleague's serious expression, Zhang Qiao looked embarrassed, "Is it so like kidney deficiency? There are people who make such suggestions at every turn, but there is no harm in supplementing it, I will buy some wolfberries when I go back from work, maybe adding some wolfberries to the blood will have a miraculous effect!" Zhang Qiao began to open his mind again, and he had a crooked idea.

I don't blame my colleagues for being strange, Zhang Qiao is now wearing long clothes and trousers, an autumn white coat on the outside, tightening the cuffs with gloves, wearing a disposable hat on his head, and a mask on his face, like a dress that is about to rush to the front line of infectious diseases. It's the hottest dog day now, and the blazing sun outside is baking the earth, although there is air conditioning in the department, it's no wonder that Zhang Qiao looks like this, and everyone cares about him.

It's so hot. Each air conditioner is turned on to 18 degrees, is adding full horsepower to deliver cool breeze, despite this, everyone still feels hot, on the one hand, the glass is not completely sealed, and there is air communication outside, on the other hand, the department is full of all kinds of instruments, the heat emitted can not be underestimated, everyone is wearing short sleeves, there is a little fat and afraid of heat, already covered in sweat, on the other hand, Zhang Qiao, the bag is tight, there is no sweat on the body.

Zhang Qiao, who bows his head and does things, doesn't care about the evaluation of his colleagues about nothingness, he is immersed in his own spiritual world, since the last time he found out that he has a bloodthirsty impulse, Zhang Qiao will find "nutritious" blood every day to meet his requirements, generally drink about 30ML of blood in the early morning every day, when the seven-day cycle, this number should be multiplied by three, in the laboratory, a resource-rich place, Zhang Qiao is not worried about no food, and even he can pick and choose, choose the most suitable target.

The only thing that made him dissatisfied was that after drinking so much blood, his body not only did not turn for the better, but his skin became more and more pale, and the color of his blood vessels became more and more purple and black, especially on his feet, which had reached the point where people felt abnormal at a glance, so Zhang Qiao usually covered his skin with various things, trying not to make people suspicious, on such a hot day, he was also fully armed, blocking those parts that he didn't want people to see.

Back in the dormitory after work, Zhang Qiao likes to watch the changes in his skin, although pale but elastic, especially increased toughness, last time I didn't believe that the needle pierced the glove, but it didn't puncture the skin, which made Zhang Qiao have a new understanding of the hardness of his skin.

Looking at his pale skin, Zhang Qiao remembered Yuan Mei's description of zombies in "Zi Buyu" in the Qing Dynasty, which has a detailed division of zombies: the corpse shortly after death has a lilac body due to the lack of blood circulation, which is the incomplete form of the zombie and even unable to move freely, which is called purple zombie.

With the passage of time, the yin qi enters the body, and the corpse slowly turns white, and the zombies at this time are very easy to deal with, slow to move, afraid of light, afraid of fire, afraid of water, afraid of chickens, afraid of dogs, and even afraid of people, called white zombies.

Later, the corpse qi emitted by the corpse combined with the power of Taiyin, changing into green, compared with the white zombie, the green zombie jumped extremely fast, not afraid of people, not afraid of domestic animals. The only weakness is the fear of the sun.

In the end, after cultivation, the corpse developed again, growing a body of hair, copper skin and iron bones, agile movement, flying eaves and walls, jumping like flying, not afraid of fire, not afraid of sunlight.

As for the thousands of years of practice mentioned later, the flying stiffness that can use spells to fly to the sky and the earth, and even the countries that walk like the wind, the countries that you see are all in drought, and the drought that comes out and is thousands of miles away, and even the demon god-like skull, Zhang Qiao thinks that this is the fantasy of a novelist, how many years of history of world civilization, and practice for thousands of years at every turn, thousands of years ago the ancients were rowing wooden boats, and now there are aircraft carriers.

If there really was a zombie, Zhang Qiao believes that this must be a strange species that is different from humans, and ancient books always describe that a living person is bitten by a zombie and becomes a zombie after being poisoned, or the geographical location of the special feng shui buried by the resentment has not disappeared and becomes a zombie.

This characteristic is very similar to a virus, which exists in a special environment and can be transmitted through blood. But what kind of people become zombies? Are there any specific rules for the conditions for producing zombies? Who is buried in that giant coffin, is it a zombie? There are no answers to these questions, and Zhang Qiao feels that his head is big.

"What is a zombie virus that can exist with the body of a normal person, after death, through special conditions to make it a new species, and can spread through blood infection. Zhang Qiao thought distressedly, "Symbiosis, coexistence, contagion, transformation, what is it?" Zhang Qiao thought in a divine way, and suddenly a flash of inspiration flashed, like a lightning bolt across the fog of thinking, Zhang Qiao thought of a possibility.

In junior high school biology, it is said that the role of mitochondria in cells is very important, absorbing nutrients and oxygen, carrying out aerobic oxidation, and providing a lot of energy for cell activities.

It can be said that without mitochondria and chloroplasts, there will be no survival of plants, no plants to produce nutrients and oxygen, and there will be no animal activities, then the world will still be a chaotic prehistory, the only single-celled organisms struggle to survive, lose the mitochondria to provide energy, we will degenerate to the era of prokaryotic cells, how can there be such a colorful and beautiful world where all things grow today, and it is impossible to appear the primate of all things - human beings.

The study of mitochondria and chloroplasts has always been valued by the majority of scientists, and when analyzing their genetic material, scientists have found a peculiar phenomenon: mitochondria and chloroplasts have relatively independent DNA and its transcription and translation systems, indicating that they and other components in the cell are not the same source.

Hundreds of millions of years ago, prokaryotic cells engulfed each other, large prokaryotic cells engulfed small prokaryotic cells without digestion, small cells gradually transformed into mitochondria and chloroplasts, and large cells gave up their own respiratory and photosynthetic systems to form symbionts, they cooperated with each other, improved efficiency, and finally won evolution, and let their genes continue to this day. This is the theory of endosymbiosis.

Thinking back then, the ancestor bacteria of mitochondria and chloroplasts, as a weakling, did not give up after being devoured, survived with the strong through a mutually beneficial relationship, and kept their genetic system not assimilated, this is not a success, the latest research results show that mitochondria are also involved in the differentiation and reproduction of cells, cell growth and apoptosis and other processes, if mitochondria really have their own consciousness, then he must know that time will tell, he is the ultimate winner!

If the zombie virus also follows this theory of internal symbiosis, then there must be a way to coexist harmoniously with him, Zhang Qiao remembered the black spikes that grew from the red blood cells under his microscope, which may be a manifestation of symbiosis, the zombie virus parasitizes the red blood cells, destroys the red blood cells, ingests some unknown nutrients in fresh red blood cells, and in turn he modifies the red blood cells to make them extremely vital and lethal. In this way, zombie bloodlust makes sense.

After the death of the person, and then activate the zombie virus in a special environment, the lack of blood circulation and the initial reproduction of the virus, the corpse is purple, this is the purple zombie, with the zombie virus will completely transform the corpse, the corpse will gradually turn white, and regain the ability to act, this is the zombie zombie, at this time the zombie is eager to get fresh blood, get sufficient nutrients, so there is a strong bloodthirsty impulse, the back of the green zombie, hair stiff, may be the zombie virus to further transform the human body, give it different abilities and characteristics, can better survive, survive and reproduce, is always the ultimate instinct of the creature。

Zhang Qiao recalled his state, the beginning of the alternation of cold and heat, the heart burst, may be the process of the initial transformation of the blood of the zombie virus, a cycle of seven days, after 7749 days to complete the transformation, he began to have a bloodthirsty impulse, looking at his pale skin, purple and black blood vessels, now it should be almost the stage of white zombie, it is written in the book that white zombie is afraid of light and fire, he doesn't seem to have such characteristics? I can't believe that the ancients wrote books, and there may be a lot of conjecture, so I can only refer to it, and I have to experiment with the things I am afraid of one by one to see what the zombies are afraid of.

Zhang Qiao suddenly remembered the beginning of a TV he watched when he was a child, "I Have a Date with Zombies", which said that zombies are born from the resentment and filth of heaven and earth, not old, immortal, immortal, not in the Three Realms, abandoning the six realms with sentient beings, using resentment as strength and blood as food in the human world. It seems that the ending of the zombie is not very good, look at yourself, it seems that there is no sense of resentment and loneliness, "Whatever, the days are still going to pass, and the zombie king in it is so powerful, if he can be as handsome as Tianyou, and it seems that it is not bad to be accompanied by a beautiful celestial master" Zhang Qiao is always so Ah Q spirit, it seems that no matter how difficult it is, he can't stump him.

It seems that it is likely that there is a zombie in the giant coffin of the ancient tomb, which was sealed by those long nails, and as a result, the hospital accidentally dug up the seal while repairing the building, so that the zombies inside woke up, it seems that this creature is indeed intolerant of heaven and earth, and was burned to death by lightning before turning over, Zhang Qiao slipped down the ancient tomb that day, it is likely that he stepped on the zombie fangs and was poisoned by the corpse, so it became today's situation, and the corpse teeth have already turned into a pile of sludge after completing the mission after the virus spread, no wonder Zhang Qiao's shoes have a big hole, but he can't find anything.

If Zi Zhuang is a semi-finished zombie, then Bai Zhuang can be regarded as a zombie entry, Zhang Qiao was injured for more than two months, and successfully changed from a small laboratory doctor to a glorious, and may be feared by everyone - zombie!
