In the era of disaster, viruses swept the world, and animals and plants twisted and mutated. Human beings are huddled within high walls, and outside the walls, seven "original disasters" with different rules are overlooking all living beings. Lin Shen, a young man imprisoned in a mental hospital and diagnosed with severe delusion, is waiting to be sent to the city wall to become cannon fodder for the next beast wave.
No one knows that his "delusions" can distort reality. When he believed that he had the key, the key appeared in his pocket; when he was afraid that the patient would die, the patient died inexplicably. This ability is a curse, causing him to bear the casualties of innocent people and be on the verge of collapse in self-doubt.
In order to survive in the disaster-ridden wilderness, he embarked on a crazy path of evolution: through extreme self-deception, he made his cognition slip into the abyss - he began to "believe" that he was also a kind of disaster. The price is that when hunger strikes and he is unable to digest external monsters, he can only eat his own left hand.
After falling into coma from severe pain, he scratched the itch with his left hand in a daze, only to realize that his limbs had regenerated. Since then, he has become a walking paradox: he has the heart of a human but is capable of disaster; he constantly deceives himself, and the world responds accordingly.
At this moment, the forces inside and outside the high wall were eyeing him, and the seven original disasters cast a playful gaze. The eighth throne named "Jiewusi Ming" is slowly appearing in the realm of illusion. Lin Shen must find the answer in this ultimate lie between himself and the world: Will he fight as the last human being, or will he rule the world as a new disaster?
