The end is coming and civilization collapses. Cold-blooded sniper Li Han used iron and blood to reforge the rules of survival, but after saving the mute girl Xiaoque, he was forced to face the abyss of human nature. Genetic researcher Su Tang masters the serum of the retrovirus, but uses humans as test subjects, only for revenge and purification. Iron Shield leader Zhao Tieshan wants to restore order through discipline, black market leader Xie Lin secretly controls the circulation of serum, and machine craftsman Chen Xiu is secretly building a weapon that can destroy the control system. When serum mutates and zombies evolve, who is the real monster? Is it the most ferocious virus?
When Li Han led his remnant troops to suppress the zombie tide, he accidentally rescued Xiaoque, a mute girl who could comfort zombies, which attracted Su Tang's attention. She used the excuse of treating prosthetic limbs to get close to Li Han, but in fact, she implanted virus samples into his blood to track the mutation pattern. After Zhao Tieshan discovered the connection between Xiaoque and zombies, he wanted to execute her to 'purify the camp'. Li Han went up in a rage and killed three sentries, completely breaking with Iron Shield. Xie Lin took the opportunity to spread rumors, claiming that Su Tang was the source of the virus, and incited black market forces to encircle and suppress him. Chen Xiu exploited a loophole to copy the serum and made a device that could reversely infect the controller, targeting Su Tang. When the path of the future corpse tide suddenly appears in Xiaoque's paintings, Li Han is forced to join forces with Su Tang to track down the truth and discover that the virus is a biological project set up by humans to select the 'fittest'. The serum is not an antidote, but the key to awakening - and what really holds the key is Xiaoque's silent childhood memory. Su Tang's revenge plan and Zhao Tieshan's iron rule will jointly detonate a civilization purge that is more terrifying than zombies. Long-term foreshadowing: In Xiaoque's painting, a strange man who looks the same as Li Han appears, standing in the middle of an unpolluted city.
