Diary of the Undercover Demon Lord

It is said by everyone that the leader of the Demon Cult was defeated by the Righteous Alliance and fell off a cliff, dying without a chance to survive. As everyone knows, he managed to survive, and even changed his appearance and sneaked into the court... Became a glorious clerk! I'm an undercover agent, so I'm not shabby. … And many years later. Bai Fei, the former leader of the Demon Cult, current deputy governor of the Demon Suppression Department and the new leader of the Good and Demonic Alliance, said this in an interview with reporters. "Actually, I really just wanted to go undercover for revenge at first..." "It turned out that after three years and three years, I went undercover and became the boss of the Good and Evil Alliance."
