Start with a rent-collecting magical girl

Liao Baiyu traveled to the world of "magical girls" and "nightmare beasts". Not only did he have the strongest chaebol at the beginning, but he also awakened the super power of a random magic item every month.
Looking at the strange magic props in front of him, he couldn't help but fall into deep thought.
In order to survive in such a crisis-ridden world, they have to hurry up and be labeled as evil chaebol villains and be eliminated by righteous magical girls.
Liao Baiyu made up his mind to take a preemptive strike, study these strange props, and use them to become an excellent magic girl special trainer!
Make money? To gain power?
Times have changed!
