Who does the full-time mage say Mo Fan is going through the back door?

According to the full-time mage, the person who enters through the back door in Mo Fan is Mu Bai's lackey. Mo Fan wore a strange pendant and slept in the mountains. When he woke up, the whole world changed. The school curriculum became the basis of magic theory. Mo Fan only studied the knowledge of magic theory for three months, and did not get good results in the senior high school entrance examination. In order to attend the magic high school, Mo Fan's father, Mo Jiaxing, asked someone to find a relationship and spent the price of a house to send Mo Fan to the high school campus. This high school is Tianlan Magic High School, and the school emblem is a Chinese character. After arriving in the classroom, the class teacher gave everyone the school badge and explained the purpose of the school badge. The head teacher told everyone that once a certain magic is awakened, the school emblem will show the corresponding color. However, sitting in front, Mu Bai's lackeys teased and said, It's good to sit here. I came in through the back door.
