Slay Demons and Monsters to Become Stronger!

I transmigrated into an age of demons and monsters, and opened my eyes in a ruined temple, waiting to die. Outside was a living hell where people ate their own children. Inside lurked bloodthirsty, savage mountain demons. Then I heard a cold notification in my mind: [Slain “Corrupt-Claw Mountain Demon.” Cultivation +4!] [Activated the Record of Demon Slaying: Kill demons to grow stronger!] From then on, while others fled from demons, I sought them out. While others ran for their lives, I leveled up. From mountain demons and corpse ghosts to thousand-year-old great demons and ancient calamities... my blade only grew faster with every strike. Until one day, I cut off the head of the being the world worshipped as a “god.”
