How can any teacher teach students to never show their faces?
Su Yan met one.
Not an ordinary school, nor an ordinary teacher.
What this school teaches is not language, math, English, politics, history, geography, and biology, but exorcism.
While they were still reading textbooks, Su Yan was kicked off to the battlefield by his master, saying that true knowledge comes from practice.
Su Yan always felt that meeting such a teacher would be the end of his life.
