Lao Wang, the former teaching director of the technical school, traveled through time to cultivate immortality, took over the Hehuan Sect, which was on the verge of bankruptcy, and awakened the teaching system of all realms.
While another sect was working hard to refine elixirs, he took his problem disciples across the world to do internships: zombies made batteries, tree demons worked as gardeners, and talismans compiled the Internet.
What was once a romantic school was suddenly transformed into the top polytechnic vocational school in the world.
"Don't call me Sect Master, call me Principal Wang!"
