I Have a Tiandao Academy

Traveling through the fantasy world, Ye Xuanyuan became the dean of Tiandao Academy. The academy is empty and overgrown with weeds. There are also a lot of book IOUs and a lot of lists of traitors. Five hundred years ago, the demon monkey stole the yin and yang stick of the universe and became the demon lord. This demon should be punished. A thousand years ago, the nine-tailed demon fox stole the "Celestial Beauty Technique" and became a demon saint. This demon should be killed. Ten thousand years ago, Immortal King Zixiao borrowed the "Tianwu Divine Code" and failed to return it after the due date. He must pay back 100 copies of the Immortal Code. One hundred thousand years ago, a green lotus in the Sea of ​​Chaos borrowed the "Chaos Transformation Diagram". If it was not repaid overdue, it had to pay off the debt with its life.
