Start by Killing Monsters and Becoming Stronger

Traveling through the troubled world of monsters and demons, you open your eyes and wait for death in a ruined temple. Outside is a hell on earth that exchanges children for food, and inside is a mandrill with bloodthirsty and rotten claws. Until I heard the cold reminder in my head: [Kill the 'Rotten Claw Mandrill', cultivation +4! [Activate "Monster Slaying Record": Kill demons and you will become stronger! From then on, when others hide from monsters, I look for them, and when others run for their lives, I level up. From mandrills and corpses to thousand-year-old monsters and ancient disasters... My sword cuts faster and faster. Until one day, I cut off the head that was worshiped as a "god" by the world.
