Perhaps because of his bond with animals, Lin Feng traveled to a different world where beasts were the main focus. When he learned that this was a world where humans and beasts coexisted, how to become stronger through spiritual beasts became his pursuit. When he awakened his talent to control beasts, he also awakened a nine-story demon tower in his body. The nine-story demon tower can suppress all demon beasts. As long as he contracts with the spirit beasts and kills and suppresses the demon beasts, he can obtain the source of life, elemental power, skill proficiency, etc. From the demon beasts and everything else the spirit beast needs to become stronger. "What?! The legendary mythical monster, come into my monster tower and stay. When I finish taking care of you, your skills and bloodline will all be mine. Hahaha" Lin Feng, who mastered the nine-story demon tower, has since reached the pinnacle of beast control.
