The end is coming, red mist covers the sky, zombies are rampant, and alien species breed. Humanity has fallen from the top of the food chain into the quagmire, order has collapsed, and the weak are preying on the strong. When he was eighteen years old, Lu Xingchuan was regarded as a burden by his family. He was deceived out of the safe base by his cruel parents and brother, and was left as a "bait" among the corpses in the city in exchange for evacuation quota for his family of three. Being bitten, betrayed, and despaired all at once, Lu Xingchuan awakened strange spiritual powers on the verge of death—emotional pollution and mental parasitism. He can draw strength from blood and fear, and use his yandere-like paranoid love and hate to tear apart the sanity of others bit by bit. The good boy who was once docile and pleasing is gone, replaced by a madman with a gentle smile and ruthless attacks. He saves and destroys people, forms a free-spirited doomsday team, and travels among major bases as a "businessman," "information dealer," and "scavenger," living to his heart's content while weaving a web of revenge. When his family was at the end of their rope and knelt before him to beg for a way out, Lu Xingchuan smiled as well as before: "Don't be afraid, I'm the softest." Only this time, his heart beat only for himself.
