On May 11, 2026, one-third of the world's human population mutated at the same moment. There is no virus, no contagion, just suddenly - your neighbors, teachers, relatives, turned into zombies without reason and only with attack instinct.
Lu Ci woke up from the upper bunk in the college dormitory, his memory was blank. He couldn't remember who he was, what happened yesterday, or even his own name - the phone told him that his name was Lu Ci. He was the only living person left in the entire dormitory building. Outside the door were zombies banging on the door. The sun outside the window hung in the sky and never set. Fifteen days of extreme day and fifteen days of extreme night, the earth's day and night rules have been completely rewritten.
His only weapon was a metal pole detached from a mop. The only advantage is an anonymous post found on a phone with a broken screen - the zombie's weakness is not the brain, but the heart. Penetrates the heart and kills with one blow. Hitting the head can only slow it down, not stop it. They hunt by sight during the day, but can barely identify stationary objects; in the polar night, their vision degrades, but they produce crazy phototactic responses to any light source. There are always two or three of them attacking together, and their running speed is no different from ordinary people.
This is not an act of God. This is a carefully designed game.
Lu Ci didn't know who made the rules, or what role Jinhua Biotechnology played in this game, or why he had lost all his memory, but his body retained a fighting instinct that shouldn't belong to a college student. He only knows one thing - in this extreme day where the sun never sets, stillness is the only invisibility, and the heart is the only way to hide.
