Taming Strange Beasts in an Infinite Cycle of Reincarnation

How many times must you die to defeat monsters trillions of times stronger than you? Du Yin faces this problem. Ever since he was young, he has had a knack for attracting strange beasts, and as he grew older, the beasts that appeared grew stronger too. The Grim Reaper who claims lives, monsters no one can look at directly, or terrifying babies humming nursery rhymes. How is he supposed to defeat them? Or would containing them be the best option? By chance, he gains the Eye of Reincarnation and All Things. Every time he dies, he returns to the scene of his most recent birthday. He chooses to make a pact with a demon, gaining the power to devour strange beasts. Will he find a way to break the endless cycle, or uncover the truth behind it all?
