My Pet Beast is really not an Evil God Novel

Gary Smith enters a world of beastmasters where an ancient taboo has resurfaced and an evil god lurks. In this realm, everything from fauna and flora to elements can become a pet beast, with powerful ones forming their own secret realm ecosystems like the Yellow Spring and Skeleton Kingdom. Beastmasters contract with these creatures, cultivating their spiritual power. After experiencing the "Taboo Sun," Gary gains the ability to extract materials and create "Secret Food." By combining specific ingredients, his pet beasts can evolve into powerful entities. The "Evolutionary Secret Food" can transform a pet beast into the Dusk Dragon God, capable of creating a "Dusk Domain" that corrupts the world. "Skill Secret Food" allows pet beasts to acquire any skill, while "Sacrificial Secret Food" manipulates time and challenges divine beings. Gary's unique beast control style manifests in creatures like the Spider Shadow, which devours ancient dragons and weaves dreams, the Red Master that pollutes realities, and the Devourer of the Realms. Despite his beasts' formidable and seemingly malevolent nature, Gary insists they are merely peculiar, not evil gods.
