"When transmigrating as a Singular blood cell that undergone awakening by accident. By a stroke of miracle, I gained the 7th star rainbow grade system, Mastery over invincibility and create my own path through this hectic apocalyptic world of snow and strangeness."
When a meteor blankets the world in contaminated snow, humanity freezes - and some who die rise again as frostwalkers. On the seventh day, a global awakening grants powers to survivors. Lin Xiaoyu, a timid high‑schooler betrayed by his girlfriend and best friend, fails to fully awaken. Inside him, a single awakened blood cell - Li Jianyu - transmigrates and claims a miracle: the 7th Star Rainbow Grade System. With dominion over blood, infinite regeneration, and a system that grants near‑anything, Jianyu could leave and take a stronger host. He stays. Why? Because he's entertained by the mess. Ruthless, blunt, and opportunistic, Jianyu will exploit every mission, every loophole, and every weakness to survive - and to dominate a frozen world that's only just beginning to thaw.
