After transmigrating to another world, Xue Yi knew no one and had nowhere to turn. After graduating from college, he became unemployed, until a chance opportunity brought him a job as a substitute martial arts teacher at a high school amid reforms to the college entrance exam.

While other teachers taught calisthenics, he taught cultivation techniques. While other students were still preparing for the college entrance exam, his students were already out conquering the world and defending their homeland: ...

I’m a professional at teaching students to cultivate. If one class isn’t enough, I’ll take on a whole school, then an entire city, then a country. Still not enough? How about a whole cultivation world? That’s right, an entire cultivation world is now a cultivation force I built from the ground up!

Time passed, and before anyone knew it, he had ushered in an era of cultivation. Years later, every student under his tutelage had become an elder statesman of the global cultivation world, commanding a region and earning a mighty reputation!

“Something’s wrong, Principal Xue! All three hundred spatial gateways have collapsed! The enemy is about to land on Earth and push into the heart of Jiuzhou!”

“Quick, bring my three hundred students here. Each of them can guard one gateway!”

“Do you mean the three hundred disciples in the top ranks of the Dragon List?”

“No need. Any three hundred will do!”
