The Good-For-Nothing 10-Year-Old Elder Begged Me to Take Over

After time travel, the useless female disciple who was about to be kicked out became an elder of the college with a silver needle. She was born with an unruly love for freedom and wanted to run away as soon as she picked up a small burden. However, she was poisoned by the hateful old man who forced her to stay in the academy. She spent the college's money like water, whipped the young disciples all day long, recruited dandy boys, and devoted herself to bringing down the college. Hello? What's going on with these villains? It's not good for you to be so obedient and sensible. How can I bring down the academy like this? There is also this person of unknown origin. Are you a monster? Why do you come to seduce my soul?
