I Am Evil, Is It Unreasonable to Bring Out a Group of Demons?

[Exotic beasts + farming + ease + no heroine + accepting disciples + invincibility] Su Li traveled through time and became an evil spirit that... Eats everything. Fortunately, he has strange abilities, such as growth, immortality, knowledge, and swallowing, so he managed to survive. Moreover, he has activated the master-disciple return system, and the apprentice's cultivation can be returned a hundred times! Soon, he discovered that the world was a mess. In order to clean up this dirty and rotten world, it began to recruit disciples like crazy. [Ding, it is detected that the disciple gains one year of skill, and one hundred times the skill is returned to the host a hundred times! "Master, those dog officials embezzled the disaster relief money. I made them into scarecrows and hung them up. They are still hanging around outside now." "Master, I used the magic you taught me to turn the flower picker into a female body and threw her into the bandits' den. Her screams could be heard three miles away." "Master, I've long disliked the dog emperor of Dayuan. How about we take this seat and sit here?" "Master, I have surrounded all the leaders of the 'well-known and upright' families. Do you want me to capture them all and serve as your servants?" Su Li: You disciples who like to make trouble, be my master! As a teacher—— I'm really pleased, hahahaha!
