Starting with a Dog, You Develop an Emperor-Level Beast?

[Beast control + training + semi-invincible + decisive killing + overhead world] An emperor-level monster appeared in the sky above the city, and its terrifying pressure put the entire city on high alert!​ Countless beast masters were trembling with fear, and even the top experts turned pale. Only Chen Yu was apologetic: "I'm sorry, I forgot to put away my pet beast..."​ … Chen Yu travels through the beast-controlling plane, starting with only one dog, but unexpectedly awakens the [feeding to become stronger] system!​ As long as you feed your pet beasts, they can evolve rapidly, grow crazily, and even break through racial restrictions and become an emperor-level existence that threatens the world! The cute and adorable Samoyed cultivated an emperor-level winged wolf, stretched its wings high in the sky, and cast a shadow that once plunged the world into eternal night. He raised the octopus bought at the vegetable market into an imperial-level deep-sea disaster and hunted and ate it in the center of the Pacific Ocean. The world was so frightened by the radar image that he immediately sounded the black doomsday alarm. From a small butterfly found in the wild, he raised it into an imperial-level Moon Shadow Butterfly. When it formed a cocoon and was reborn, a new full moon appeared in the sky. With countless emperor-level pet beasts, Chen Yu easily destroyed demons around the world and gained the love and admiration of countless people! People were puzzled and asked Chen Yu why he didn't want gold, silver and jewelry, but went to a dangerous place where demons gathered. Chen Yu was surprised: "What? Didn't you see that I have a bunch of pet beasts to raise? If I don't destroy the monsters, how can I get so much fresh flesh and blood to feed them?"
