February 1, 2030 A.D. is known as the Day of Transcendence.

On this day, Dr. McLean, a well-known biological research expert in the North American Federation, successfully developed an X-1 agent that can strengthen the human body, shocking the world.

The injection of X-1 medicine can greatly strengthen the muscles, organs and brain, not only the body is strong, the mind is smart, and many insurmountable terminal diseases are also cured with the enhancement of resistance.

In the same year, Dr. McLean's Beeplige company sold worldwide at a low price of $10,000 a piece. Such a price, which even ordinary people can consume, made X-1 drugs quickly become in short supply.

For a time, Transcendent Company was regarded as the greatest company in the world, and the global human beings have also entered an unprecedented stage of super-speed development because of the improvement of the overall quality.

In 2040 A.D.,

After ten years of development, Beondalian's pharmaceutical has launched the fifth generation of X-5 enhancer, almost all human beings have completed injections, and the super vitality has made the global population quickly exceed 10 billion.

However, also on February 1, after hundreds of millions of humans were injected with the latest boosters, their bodies underwent terrible changes, and people lost their will and turned into zombies like the living dead, desperately attacking those around them.

Those who are attacked are also turned into hideous zombies after death, a terrible X-virus raging all over the world, and even intact humans can be infected with the virus and become zombies at any time.

When humanity reacted, billions of humans turned into zombies, their homes were in danger, and the surviving humans began a long escape.

History is known as Cataclysmic Day.

Seeing that the situation was irreparable, governments took action as soon as possible, and even did not hesitate to use heavy weapons to bombard the city where a large number of zombies gathered.

However, the terrifying thing is that the zombies decompose into countless bacteria and microorganisms after being crushed to pieces, which come back together to form a huge brood.

New, more powerful zombies have been bred in the brood and reoccupied the city, once again giving humanity a huge blow.

Just when humanity is in despair, several mysterious forces that hide in the world emerge in the world.

The world of cultivators led by the Chinese cultivators, the South American superpowers, the Norse gods, the Southern European Holy See, and the Dark Council has entered people's eyes.

They cleared dozens of huge cities and built defenses against zombies in extremely esoteric ways.

These cities became the last safe places for humanity.

In Huaxia.

Xiao Boqing, known as the eight-armed martial saint, held the bull's ear of the Chinese monks, formed the Huaxia War Alliance, and wrote the basic cultivation method "Nine Forging Opera" for all Chinese people to practice to resist the infection of the X virus.

Later, with the Battle Alliance Kyoto City as the center, the eight major cultivators in the land of China were born, and established the Ten Thousand Buddha City, the Emperor Stepping Peak, the Divine Sword Peak, the Dao Palace, the Beast Maze City, the Jixia School Palace, the Cangbei Fort, and the Eight Great Cities of Wanliu City, and sheltered tens of millions of refugees with the power of one faction.

He also sent elite disciples to various parts of the land of China to establish towns to receive civilians.

Since then, the displaced survivors have had a direction to flee.
