Traveling Through the Dragon Clan: I Treat Lu Mingfei's Split Personality

My name is Xu Liuming, a psychiatry intern. Just when he was about to become a full-time official, he traveled to the world of "Dragon" and became the psychological tutor of Kassel College. At the point when Lu Mingfei was invited to join Kassel College. The system said that I can only go back after curing Lu Mingfei's split personality and helping Lu Mingfei become the new "king", but... Lu Mingfei's other personality is the little devil Lu Mingze! Even if I have read the original work, it is still at the level of lv1 versus lv9999999. Is it going to be hell difficulty at the start? Fortunately, there is less than... A week left before Lu Mingze's appearance. However, this Lu Mingfei seemed to be different.
