The life of Su Mu, an ordinary office worker, was disrupted by a strange note that was automatically spit out from the company's printer. There was only a line of cold typeface on it, counting down seven days until the zombies broke out. He dismissed it as a bad joke or a system glitch and dismissed it. However, the same warnings did not disappear. They came one after another, appearing in the scrolling subtitles on the huge advertising screens in the mall, occupying the lock screen every time he unlocked his phone, and even whispering repeatedly on the edge of his tired dreams. The numbers are decreasing day by day, like a guillotine hanging above your head. Fear grew from the cracks of doubt. Late at night on the sixth day, Su Mu finally succumbed to the cold uneasiness as he looked at the blood-red "1 day left" on his phone. He spent all his savings and hurriedly hoarded supplies. Before dawn on the seventh day, he hid in the cold, damp and isolated basement of an old house in the suburbs. When the first shrill, inhuman howl tore through the tranquility of the outside world, and when the phone screen lit up, pushing the bad news of the collapse of civilization and the fall of the world, he huddled next to the supplies, feeling a trace of sad luck in the darkness that he had taken the lead. However, there was a knocking sound on the old floor above his head, dull and regular, and a cold voice that should never have appeared here penetrated the crack in the door and called his name.
