Su Mu unexpectedly comes into possession of a mysterious diary—only to discover that its owner is none other than his future self.

According to the diary, humanity is on the verge of extinction, and Su Mu is the savior destined to save the human race.

Following the diary’s guidance, Su Mu successfully awakens the one-of-a-kind EX-Rank Talent 【Death Copy】, which allows him to obtain the SSS-Rank Talent 【Twelve-Hour Death Rewind】, the ability best suited for him.

From that moment on, Su Mu embarks on an invincible path paved with countless deaths—dying, growing stronger, and slaughtering his way through the Ten Thousand Races.
