Throughout human history, every outbreak of a virus, if it cannot be contained in time in the early stage, then soon, the virus will spread rapidly. Today it may be 1,000 people infected, tomorrow it may be 35,000 or even 10,000, this is not an increase according to a certain number, but a geometric multiple! As for the end, it can only be a complete defeat of the virus by human beings, or there is really no host that can infect them, and there are only these two results!

On April 22, 2020, the new virus was first detected and named hemophagocytic virus.

On November 3, 2020, the virus, which had been dormant for half a year, once again took the ocean from the hands of humans.

On December 7, 2020, infected sea monsters attacked land across the globe. In one night, humanity had all but lost control of the coastline, and there were no more humans except for a few large forward bases.

In January 2021, a large number of birds that had eaten the dead corpses rushed inland! More and more people and animals were infected, eaten, or became new mutants, and later the human infected were collectively referred to as zombies, and the animal infected were called monsters.

By April 2021, Japan, the United Kingdom, South Korea and other small coastal countries, as well as the whole of Australia, completely fell. Large countries such as China, the United States, and Soviet Russia have built numerous war fortresses in their countries with provincial capitals as the center and city-level cities as the fulcrum, and the great exodus of the Chinese people has only come to an end, but without exception, they have all suffered heavy casualties, and the world's population of 7 billion is estimated to be more than 4 billion points.

With the fortress of war, humanity was finally able to take a breath, but then there was the question of land, food, and how to live. In desperation, governments can only implement military control, and the house of four people used to live is now occupied by forty people!

Although ordinary ammunition is still being produced, the largest production capacity is reserved for special ammunition such as armor-piercing bullets and incendiary bombs. Because as the war continues, humans have discovered that ordinary guns and bullets have to hit the vital point if they want to destroy zombies, not to mention monsters covered in scale armor. Each war fortress is surrounded by a ring of walls up to 50 meters thick and up to 100 meters high, one fortress has four entrances and exits, the gate is made of special steel, and one gate weighs more than 40 tons. On the city wall, rows of battle defense guns, huge muzzles flashing with icy cold light, facing the outside. A little bit later, all kinds of individual air defense weapons and automatic air defense missiles are scattered and scattered, but any enemy who comes to attack will certainly not be able to avoid this impermeable defense! As for the air force, it has also become history, because as soon as a fighter plane takes off, it will immediately be smashed by a monster flying in the air!

On June 11, 2021, the well-defended New York City was breached by countless sea beasts, and on the 15th of the same month, the Chinese state of Shanghai was attacked. The same scene is constantly being staged in the world, and the results are all the same.

......With a deafening roar, a huge mushroom cloud appeared over Hawaii in the Pacific Ocean, although it was daytime, but the dazzling white light was still dazzling, fortunately there was no one around!

Having lost several war fortresses one after another, the U.S. government couldn't sit still, so a nuclear bomb exploded. At first, the Americans wanted to put it in Japan, but China and Soviet Russia did not agree, and finally chose Hawaii.

The effect of a nuclear bomb is obvious, and a large number of sea beasts entrenched in Hawaii are completely wiped out in an instant. But just before the nuclear-armed states made up their minds to follow suit, a satellite image completely plunged them into an ice cave. Three days after the nuclear bombing of Hawaii, there were some sea beasts entrenched there, but their size was fully doubled! Using a nuclear bomb would only make the monster stronger, and the strong nuclear radiation could easily kill human beings, but it became a catalyst for the evolution of the monster! Since then, the nuclear bomb cannot be used as a weapon of mass destruction unless it is against an extremely strong single target.

On August 1, 2021, the world's existing countries established a coalition government through video conference, with China, the United States, Soviet Russia and the European Union as the core, to lead mankind to resist the invasion of monsters and gradually eliminate them.

Under the guidance of the coalition government, as time goes by, humanity continues to improve the defense of the war fortress, and gradually it can finally compete with the land monsters, and the fortress is breached, and the occurrence of fewer and fewer things, the stalemate stage of the two sides has arrived.

Although the world's population has decreased, the land is gone, and crops cannot be grown.

Some countries began to send armies to reclaim some land from the monsters for farming, but the small fortresses that were built in a hurry were soon breached by a large number of monsters, and the losses were not insignificant. Later, the coalition government urgently negotiated and formulated a "siege plan", and mankind slowly acquired some land.

The so-called siege plan is to build a new city wall along the wall of a large fortress under the protection of a large number of troops, and then destroy the monsters in it after the wall is closed.

In November 2021, after the unremitting efforts of scientists in China and the United States, a magical substance was finally extracted from the monster's body, a new substance derived from the virus. Through a large number of animal experiments, scientists finally determined that injections containing this substance can modify the body so that ordinary people can also have great strength and have no side effects. Although there is no study of the hemophagocytic virus, this discovery is still a huge advance that can change history. After that, the effects of the monster's fur, scales, and bone claws were slowly excavated, that is, to make armor or some weapons.

The kind of substance extracted from the monster's body is mainly located in its heart, as long as blood is taken from its heart. After that, governments began to send some armies to hunt monsters in a planned way, and although they were sometimes hunted, they also brought back a lot of blood. Through separation, that substance was produced in batches, and as for who to vaccinate, at the suggestion of scientists, the government unanimously decided that half of it should be used for military use, and the other half of the entire staff would voluntarily sign up and be randomly selected. The reason for this is that scientists want to see if the offspring of this enhanced human will evolve in the same way.
