They Call Me Lord Demon King

My name is Yuan Du, from the seventh generation of the Taoist Academy. From the cultivation of real demons to the Taoist cafeteria, they all belong to the seventh generation of immortal cultivation. The cause of the matter is simple—— The Cultivation Alliance was short of a death squad, and my father looked at me like I was looking at rat excrement, so I got angry and signed up. Shadow action, glorious selection. Later, I got involved with the third master of the Demon Realm, and the Demon Emperor had to give me three points of noodles when he saw me. But later—— I can't contact my upline. "Old man, I want to go home." Damn it, whoever wants to be this devil can do it, I won't do it anymore.
