Trading Lifespan for a Chance to Live

Manshi Li, an ordinary office worker, transmigrates in his sleep. He wakes in a desolate wasteland crawling with mutated monsters, with a “rip-off” System bound to him. Every survival necessity, from steamed buns and drinking water to a dagger for self-defense, must be purchased with his own lifespan. He has barely arrived before hunger and monsters threaten him from all sides. He watches his remaining years dwindle, but can only grit his teeth and trade his life for survival. To stay alive, he grips the dagger he bought with his lifespan and dodges and outmaneuvers the twisted mutants across the ashen wasteland, battling them to the death as he struggles against all odds to find a sliver of hope for prolonging his life.
