Versatile Mage: My Sworn Sister Mu Ningxue Has Turned Black!

In the early stage, it follows the book's route, medium pace, no nanny, full magic tree points, full technology tree points, multiple heroines but no stallions, and sufficient emotional lines. Magic tree development route: Because I know all the endings in the book, I can advance the things in the book in advance: thunder system, ice system, demon system... Strengthened control of stars... Ice crystal brake bow... While others are still worrying about strengthening the stars, he has already upgraded all the stars to the highest level at the moment of awakening; while others have one or two systems when awakening, he already has multiple systems... Technology tree development route: Because there is scientific knowledge in the brain, it can advance scientific knowledge: physical knowledge, biological knowledge, atomic knowledge... While others are still using healing magic to heal their injuries, he already has nano-robots that can quickly repair injuries; others feel humbled by the emperor monster because of their weakness, but he already has magic nuclear bombs and satellites for precise targeting; others are still sad about why there are so many sea monsters in the ocean, and he has led his aircraft carrier fleet across the Pacific... The main heroine's darkening route: Chen Lian was adopted by her mother since she was a child and was her childhood sweetheart with Mu Ningxue. With his company, her personality became much more cheerful. Chen Lian was also pleasantly surprised by her change, but gradually as she grew older, she gradually realized that something was not quite right... When he was having normal interactions with other members of the opposite sex, he always felt that Mu Ningxue's eyes were dark and strange; when he was walking alone, he always felt like someone was following him... Only then did he realize that she was crooked.
