Before dawn, night covered the sea level. An unknown bird flew over the sea with a cry at the top of its voice. The waves crashed against the cliffs, as if to vent their frustrations. Looking up from the cliff, I could vaguely see two people standing on the cliff.

The sea breeze blew on the two men, and one of them looked at the sea with both eyes, and suddenly said:

"The time has come."

The other nodded absentmindedly and pushed his eyes on the bridge of his nose.

"I've been waiting for so long, and I've been laying out this for 30 years." He sighed.

The exhaust gas finally succeeded in occupying the last piece of pure land, and the originally blue sky was full of exhaust gas. In the achievements of human history, people have drained the last drop of oil and cut down the last tree; Sewage slowly encroaches on the ocean, land is degraded, and deserts slowly encroach on the plains; Tall buildings can be seen everywhere, and a variety of factories can be seen all over the field.

The number of people has declined dramatically in recent years, and 9% of the world's population occupies nearly 65% of clean, high-quality resources.

The gap between the rich and the poor continues to widen with the development of society, with the rich getting richer and the poor getting poorer. I don't know who roared, like a bomb falling on the plain, and the uprising and revolution exploded in an instant. Demonstrations and protests intensified in the city.

The government's violent crackdown was the trigger for the protesters to form an armed force. They call themselves the "Pingli Army" and try to stand up to the government.

In the end, there was only a small local fight, and the government and the Pingli Army began negotiations that lasted for three months. The government claims that the biggest crisis on the planet is the environment, which is an issue that every human being should pay attention to, and that we should unite to solve this big problem at the moment, and when this big problem is solved, these problems of yours are small problems, and we will solve them.

In the end, the government solved the problem by simply raising the minimum number of working hours. In fact, the world government is right, the world is getting worse and worse, and the survival of mankind is imminent.

The survival of humanity is at stake, and interstellar migration is still a fantasy. Since the environment cannot adapt to human beings, only human beings can adapt to the environment.

The United Nations has become a veritable world government, integrating the world's official languages with Chinese as the main language and English as the supplement. After many and long discussions, it was finally decided to develop a gene drug to modify human genes.

As a result, the world government convened the world's top biogeneticists to jointly develop genetic drugs to modify human genes to adapt to the poor living environment.

The earth is becoming less and less suitable for human existence, and the development of genetic drugs is imminent. With the strong support of the world government, bioengineers have finally developed gene drugs and entered clinical trials in just a few years.

Gene drugs were first experimented on babies, and Sim, the chief scientist of biogenetic engineering, claimed that the baby's genes were the easiest to modify. So the first genetic drugs were injected into 10 babies in orphanages, and the babies were then taken in biological laboratories for observation.

The second batch of genetic drugs will be tested on death row prisoners, and biologists will inject a gene drug in a silver tube into the bodies of the condemned prisoners, and deport all the condemned prisoners who have injected the genetic drugs to the worst places, so that they can observe them in all directions while they fend for themselves.

Half a year later, biologists suddenly discovered an anomaly.

The condemned prisoners who were injected with the second batch of genetic drugs suddenly became unrecognizable overnight, their mouths were constantly drooling, their whole bodies were dripping with pus, and only the whites of their eyes were bloodshot.

They exceeded the worst expectations of biologists.

The condemned prisoners seemed to have become the ghosts of death, and when they saw a living thing, they went crazy and bit it. No living creature within a radius of several miles survived. They're out of control! Biologists have increasingly observed that their blood and saliva are highly contagious and will be assimilated immediately upon contact.

They're zombies!

Upon receiving the news, the world government immediately ordered the humane destruction of the 10 babies who had been injected with the first batch of genetic drugs.

The zombies quickly spread around, and the world government, in order to stabilize the social unrest, concealed the matter from the outside world and sent troops to exterminate it. But when the troops first clashed, the highest-ranking colonel in the army instantly despaired.

Zombies have a strong ability to regenerate and recreate, and the soldiers' shots can't kill them at all, and the troops sent by the World Government are quickly assimilated by the zombies in just one shot.

The zombie team is getting bigger and bigger!

The zombies are out of control, and a large number of zombies arrive in human settlements.

The people who were kept in the dark panicked, suffered heavy casualties, and zombies quickly swept through the city, and no one was left infected.

Zombies are coming! The world government can't hide.

The world is in an even bigger crisis! On the one hand, the world government ordered the scientists of biological genetic engineering to develop a serum that inhibits the zombie virus as soon as possible, and on the other hand, it sent an elite army to attack and gather all the scattered human beings. Draw an area where the zombies reunite and focus on attacking them.

Biologists quickly developed serums that inhibit zombie viruses based on the medicinal properties of genetic drugs and the characteristics of zombie viruses and the daily observation of zombies. The serum is first injected into the army. But unexpectedly, according to the data of clinical trials, all the soldiers injected with zombie virus serum died.

The world government was furious, and Sim, the chief scientist of the biogenetic engineering, explained that because there were very few people who were suitable for serum, if they wanted to use the serum perfectly, they could only test the soldiers one by one, and then inject them when the serotype was found. When the serum test agent can be mass-produced, the sero-fit test will be performed on each human being.

The world government had no choice but to agree to Sim's plan.

In the end, in the world's vast legions, only ten serofitters were found.

They are immune to the zombie virus, and the blood and saliva of the zombies do not harm them, and they have the ability to repair themselves like zombies.

These ten people are grouped together to form a special unit against zombies, and the unit is called "Restart". The World Government has mobilized the world to create fifteen weapons capable of destroying the self-healing ability of zombie cells for use by the Reboot organization.

"Restart" will be a sharp blade against the zombie wave and will be the last hope for mankind.

But at this time, the territory of mankind has been shrinking, and in the face of the wave of zombies, human beings are in a state of life and death............
