I Have a Heavenly Dao Academy

After transmigrating into a fantasy world, Ye Xuanyuan becomes the head of the Heavenly Dao Academy. The academy is empty and overgrown with weeds, and there is a huge pile of overdue book slips, along with a long list of traitors.

Five hundred years ago, the Demon Monkey Kongkong stole the Yin-Yang Staff of Heaven and Earth and became a Demon Lord. This demon must be slain.

One thousand years ago, the Nine-Tailed Fox Demon stole The Art of Heavenly Immortal Beauty and became a Demon Sage. This demon must be slain.

Ten thousand years ago, the Purple Cloud Immortal King borrowed The Divine Tome of Heavenly Martial Arts and never returned it. He must repay the debt with one hundred immortal tomes.

One hundred thousand years ago, a green lotus in the Sea of Chaos borrowed The Chaos Transformation Diagram and never returned it. Its life must serve as payment.
