Countdown: I’m Trying to Survive in Worlds of Unfulfilled Regrets

At twenty-six, Lin Zhou is diagnosed with terminal cancer. He has less than three months to live, and in his pocket is a plain diamond ring he never got the chance to give away.

After bonding with the Unfinished Business Redemption System, he is sent into one anime world after another with a single mission: prevent people who were never meant to die from dying. Every tragic character he saves earns him a few dozen more days of life. Fail a mission, and his remaining lifespan plummets as his condition rapidly worsens.

He has no combat ability, and each time he enters a world, he can draw only one rule-based support skill. But he has the advantage of knowing what’s coming, a modern outlook, and the nearly obsessive desire to live that comes with being terminally ill.

Demon Slayer, Naruto, Attack on Titan, One Piece… With nothing but an ordinary man’s body, he moves through battlefields where gods clash, using one enemy to kill another, relentlessly manipulating villains, and exploiting every loophole in the rules. In anime worlds, he’s the mastermind who’s thought of everything. Back in reality, he’s just an ordinary man, frail in his hospital bed and waiting for his girlfriend, Shen Qingtang, to feed him porridge.
