Demon Lord, She Took Her Arch-Enemy as Her Apprentice

The feared female demon Shuo Yue was seriously injured in the battle between immortals and demons. She lost all her cultivation and was forced to hide in the mortal world. In order to make a comeback, she decided to accept a talented apprentice, and after he became a master, he would use his skills to help her return to the top. She made many choices and fell in love with a young man with excellent bones and a simple heart. She taught him everything she had and passed on what she had learned throughout her life, just waiting for him to achieve great success. The young man is also extremely dependent on her, respecting her like a mother and loving her like light. It wasn't until the Immortal Sect came to encircle and suppress her that she discovered to her horror that the good disciple she had raised was actually her nemesis in her previous life - the number one God of War in the Immortal World who had personally thrown her into the abyss and reincarnated her! He worshiped her as his disciple just to stay undercover by her side, find the lifeblood of the demon world, and eradicate her completely.
