After Wandering into the Devil's Path, My Old Enemy Became My Taoist Companion

[Two male protagonists BL｜Crazy criticizing and paranoid attack × pure and firm acceptance｜High tension bond] Demon Lord Ye Jin lived for tens of thousands of years, and his days were so idle that he found a poor little boy named Ah Heng who had a ridiculously clean soul beside the boundary monument. The little guy has lost all his memory and has low cultivation level, but he is a genius in cultivation. He can do more harm to people by staying up all night to practice than by practicing magic. Ye Jin found it interesting and took him on as his only disciple on a whim. He originally wanted to make fun of him and watch him grow up, but failed and tried to trap himself into it. Teach him the magic skills, and he develops the sense of celestial beings who are pure and stoic; when provoked, he punches each madman in the face, and defends his shortcomings more fiercely than anyone else; when he stays up late to practice, he will secretly leave the best elixirs to his "unreliable master". Ye Jin went from "just having fun" at the beginning, to a maniac who said "Who dares to touch my disciple?", To a maniac who said, "Who dares to touch my apprentice?", To his heartbeat speeding up and jealousy over his disciple, the king of scrolls - he agreed to raise a collection, but why was he so interested? Ah Heng accepted death and regarded Ye Jin as the whole world. She practiced hard just to protect her master, but she didn't know why her training speed was so fast and why she was inexplicably sensitive to the hidden dangers of the devil. The bloody slaps in the face are constant, the sweet pets are daily, and the two-way secret love cannot be hidden. It wasn't until the ancient monster appeared in the world, and Ah Heng exploded the power of his soul to protect Ye Jin, that he realized that he might be the immortal who wanted to destroy the evil way back then. But so what? Ye Jin hugged him and said in a lazy but serious tone: "No matter whether you are the Immortal Lord or Ah Heng, you are the one I protect and the Taoist companion who wants to spend the rest of his life with me."
