I've Shown My Cards, I'm Only 100 Million Points Better Than Master

There are twelve peaks in Yunding Fairy Mountain. Master Fengfeng has magical powers. Jing Xiaoqi is their apprentice. When he left school, he competed with his masters. The "Nine Turns" of refining an elixir, the "Seven Edges" of forging a sword... Each one is only a little bit stronger. After coming down the mountain, he became a god in one battle. Then he hid the "Seven Edges" sword, put away the "Nine Transformations Pill", and became a teacher in the academy, teaching the most chaotic class. No one knows that Mr. Wen Tun is the war god who protects the country. He only loves the podium and listening to the sound of students reading. When the smoke rises, The chalk is thrown like a sword, and the writing on the blackboard turns into a talisman to suppress the devil. "The class is not over yet, who dares to disturb it?"
