I Forged the Monkey King

Ethan transmigrated to a world of Beast Taming, obtaining a Simplification System. He contracts a Stone Monkey with no Evolution Path, so he creates one, adding a staff, armor, and cloud. When geniuses see the Stone Monkey shatter the heavens, they exclaim, "What the hell is this Great Sage, Equal to Heaven?" As Ethan creates Divine-tier Beasts, the world goes crazy!
