This Doomsday Option Is Not Serious

Li Zhengdao, who went to Sakura to study abroad, just got off the plane. I saw a 'madman' pounce on me and bite the flight attendant to death. But what Li Zhengdao didn't expect was that the world's ill will towards him was still to come! Seeing the flight attendant who fell to the ground, an options panel appeared in front of him: [Option 1: Rush over, bite the fallen flight attendant with the zombies, and get the characteristic: zombie disguise! [Option 2: Go crazy and bite the zombie's neck. Trait obtained: Immunity to zombie virus. [Option 3: No choice, bite together! From then on, there was a "mental illness" in the world who went crazy and was not bound by morality.
