The End of the World: I Became a Sane Zombie

(Apocalypse + sane zombies + triple personality + disguised lurking + human nature) "Brother Li, why don't you have a heartbeat?" "Brother Li, why is the color of your blood wrong?" "Li Tian, are you a human or a corpse?" When others become zombies and lose their minds, he becomes a zombie and has a clearer mind than anyone else. While others were hiding from zombies to survive, he pretended to be a human and sneaked into the survivor's stronghold. While suppressing the "tyrant" personality in his body that could go berserk at any time, he also fought with the sharp-tongued "strategist". During the day, he takes on missions to kill zombies and collect soul crystals. In the middle of the night, he sneaks out of the city with his wrinkled Shar-Pei Dahei to hunt for high-level monsters. His teammates thought he was a third-level speed superpower, but no one knew his true identity was Experimental Subject No. 073—The only person who successfully fused the zombie virus and genetic medicine. But if you stay in the apocalypse for a long time, you will find that sometimes, the people who want to kill you are not zombies, but living people. When the research institute begins to search for "Experimental Subject 073" all over the city, when millions of zombies come to the city, and when the brother standing in front of you to protect you from zombies asks "Are you human?" - How do you want to answer?
