In the Cape Satellite in the near future, a doomsday disaster known as the "Cataclysm" comes without warning. Civilization collapsed in just a few months, cities were reduced to ruins, and survivors struggled to survive under the dual threats of mutated creatures and extreme climate. Xu Honglei, a former street police officer, lost everything in this catastrophe. From a scavenger struggling to survive, he gradually united a group of brothers who share life and death - hacker genius Wang Fatty, silent god of war Li Mo, biologist Dr. Liu and the shrewd and capable Zhao Qing. They established a shelter to fight against gangs and beasts, and were eventually absorbed by the "Northern Administration", the largest survivor force in the north. By tracing a series of strange events, Xu Honglei uncovered a shocking truth: the end of the world is not a natural disaster, but a man-made "cleansing." An ancient demonic organization called "Ouroboros" took the initiative to release a "demonic curse" covering the world in order to prevent what they saw as the "out of control" development of mankind. The day the truth is revealed is when the war breaks out. Xu Honglei was hunted by the organization and was forced to break with the administrative bureau. In a desperate situation, he formed the "United Front for Human Survival" and officially declared war on this behemoth that had been hidden in the shadow of civilization for centuries. This was a war with slim hope. Xu Honglei must lead his allies to find and destroy the source of the curse all over the world while fighting against the "Ouroboros" modern army, Cyborg warriors and cursed terrifying behemoths. Can Xu Honglei, a policeman from the streets, finally lead mankind to break free from the shackles and ignite a dawn for everyone on the embers of civilization?
