National Beast Control: Starting Contract with the Suzaku Demon Emperor

[Invincible] [Beasts transformed into humans] [Multiple female protagonists] [Revenge does not take overnight] [The protagonist's strength is unknown, but the beasts are invincible] Traveling through the world of national beast control, Chen Ye found that he had become the wronged person who had been cheated out of his family property and cruelly abandoned by Green Tea, and was even humiliated in front of his adulterer. Fortunately, the beast-controlling custody system was awakened just after time travel, and the beast-controlling custody system can be sent to another world for a thousand years each time! [Congratulations on getting a critical hit of a thousand times the duration of your first hosting. The duration of this hosting is: 1 million years. [Host World: Fantasy] [Please select the hosting object! Chen Ye glanced at his sick little red bird beast. [Hosted object: Red Flame Bird] [Start transmission...] [The hosting is over, your beast "Suzaku Demon Emperor" is about to return! What was sent over was a sickly little bird, but what came out was a peerless and invincible female demon emperor? Facing the aggressive dog man and woman again, Chen Ye said nothing and simply gave them a Nine Tribes Relief Fun. As his own strength increases, he can take charge of more and more beasts. Take care of a little fox and get a charming nine-tailed demon fox. Take care of an ordinary black cat and get a nine-life civet lady with cat ears... Don't these smell much better than that green tea? ! Etc! Why is his body getting weaker and weaker even though his strength is getting stronger?
