Western Fantasy: I, the Undead, Successfully Applied for the Role of Undead Mentor

Once the protagonist traveled to another world, he became an undead. After losing his human identity, he lost his life of drunkenness and luxury. "Damn it, one second you were charming in the colorful world, and the next second you were in a desolate gray land?" The protagonist expresses that he must return to human society! Keep enjoying the dance! After seeing the recruitment information, Mu Yun decisively signed up! Just run for high welfare! Good treatment! Mu Yun, who had free working hours, didn't read the recruitment carefully at all. Until the interview... "Um, are you applying for a tutor? What kind of tutor?" The dean doing the interview patted his head. "I really don't need to ask, there is no one more suitable for this position than you!" In this way, before Mu Yun could react, he transformed into the undead mentor of the Royal First Academy, Linton Academy! Note! This book is unsystematic! No system! The system exploded in Chapter 2! Jump directly from a small skeleton to high-level strength at the start! Those who mind slaughtering villages and destroying countries can leave on their own. The identity of the protagonist is actually a mentor who teaches evil people. Later, in order to become stronger, the disciples will become evil beings and the incarnation of death after becoming gods. It is recommended that those with a moral bottom line skip Chapter 25. This chapter contains the concept of a necromancer, and the massacre of villages occurs.
