Edge Demon Qi Master

The world harassed by "demons" like a tide is like an ocean shrouded in darkness, and the evil forces hidden in the depths are like giant beasts lurking at the bottom of the sea. They attempt to "change" the world and set off turbulent waves. I thought the threat was only for this moment, but I never expected that hundreds of years ago, or even hundreds of millions of years ago, countless "time bombs" were planted, waiting to explode at the right time.
