No system, no powers, no rebirth, no cheating. The apocalypse is coming, zombies are everywhere, the virus can spread through the air, everyone has been infected, and survival depends on the weak antibodies in the body.
Lin Bei relies on hard-core survival skills to survive in the wasteland. He built a farm, guarded a shelter, and gathered survivors, but he encountered unforeseen corpse transformations, betrayal and surrender, and leaks of defense lines one after another. Zombies are not scary, but people's hearts are the most dangerous.
Amid suspicion, sacrifice and raids, he stuck to his team and fought all the way to the institute to pursue the truth and develop a vaccine. The tide of corpses and looters join forces to suppress the situation, and relatives and friends leave one after another. He finally realizes that the most deadly thing in the end of the world is always the knife hidden by the people around him.
