I Have Become a Master of Magic, Let Me Find My Way Back from My Lost Ways

A man is about to become a giant of demons, and the Immortal Sect comes to persuade him to return from his lost ways? Gu An traveled through time and carried the "Three Thousand Chaos Demon Gods Picture", and began to practice "low-key" as an undercover handyman in the Blood Demon Sect. He is proficient in assassination, but he pretends to be a harmless alchemist. He kills people and seizes treasures, but he always manages to frame the blame perfectly. Decades later, he has become the master of evil and powerful. At this time, the leader of the Taixu Immortal Sect stood in front of the two armies and shouted to him from a distance: "Gu An, there is no end to the sea of suffering. When you turn around, you will find the shore!" Gu An was silent for a moment, then turned to ask the thousands of demons behind him: "Everyone, the Immortal Sect has said that they want to rescue me. What do you think I should do?" The demons roared: "Please order the Demon Lord to level the Immortal Gate!"
