My Master Is a Devil, How Can I Be a Good Person?

[Through the book + no system + no heroine + villain master and apprentice + decisive killing + dual cultivation of magical powers] Gu Chen stayed up late to catch up with the update, but he didn't expect to slip into the fairy tales written by him and become a disciple raised by the world's number one devil, Pei Wuwu. Good news, Master, take care of me. Bad news, he is a hopeless licker in the original novel. On his twentieth birthday, Pei Wuwu broke into the Taixuan Taoist Sect alone, suffered three God-Destroying Nails, and snatched the saint Ning Qingshuang back. "At the last forum, you stared at her for half an hour. Today you are an adult, and someone snatched it back for you. It is regarded as an adult gift from the master." In the original work, Gu Chen was reluctant to touch her, but instead helped her to unblock her. After that, he was lured step by step by Ning Qingshuang to steal his master's life lamp, send him soul-dispersing poison, and open the sect-protecting formation with his own hands. When Pei Wuwang was surrounded by seven sects, he still blocked the last sword for him. "No one will protect you from now on, so trust others less." But before the master's body was cold, Ning Qingshuang destroyed Gu Chen's cultivation, and used his letter of help to ambush all the old members of the Demon Sect who came to the rescue. After replaying the ending of the original work in his mind, Gu Chen looked at the saint on the couch and took the Heart Locking Gu from his master. Release him? Abandon darkness and embrace light? The next day, Gu Chen put on his clothes and went to bed, took off the Taixuan Order from Ning Qingshuang's waist, and sent the first false news to Zhengdao. Everyone is waiting for this demonic disciple to betray the master. Gu Chen just wanted to ask one question—— "My master is a devil, how can I be a good person?"
