Dying a hundred million times, I copied talents and slaughtered the myriad races

Su Mu unexpectedly acquired a diary, only to discover that its owner was his future self. The diary revealed that the human race was on the brink of extinction, and that Su Mu was the savior destined to rescue humanity. Guided by its entries, Su Mu successfully awakened the EX-rank unique talent, Death Copy, which allowed him to acquire the SSS-rank talent perfectly suited to him—Twelve-Hour Death Reversion. From that moment on, he embarked on an invincible path paved with death.
