The Demon Returns: the Sick Maid Helps Me Become a King

In this world, there exists a powerful and extremely hostile creature - the demon. They have the dual characteristics of demons and angels in mythology... Relying on the powerful magic eyes and the supernatural powers driven by the magic eyes to suppress humans. Until, a large number of awakened people with magic eyes appeared among humans. The war between demons and humans has gradually reached a balance... However, Ye Mingyu is just an ordinary high school student. His parents are both top bosses, but he doesn't even have a magic eye and can only be an ordinary person. Until one day after school, a truck crashed into him, and then he met a mysterious silver-haired girl in his dream. "I won't hurt you, trust me." The girl's whisper helped him awaken the magic eye... Allowing him to completely get rid of the ordinary label. When he woke up, the girl actually materialized and insisted on accompanying him as a "maid". Her name is Ling. Ling can communicate with Mingyu in her head and has unfathomable power. What's even more outrageous is that her fighting power is completely shared with Ye Mingyu... In other words, the stronger the girl is, the stronger Mingyu is. But she never mentioned who she was or what her purpose was. What surprised Ye Mingyu even more was that Ling was extremely possessive... As long as a girl comes near him, she will lose control and run away. But what's even more outrageous... Another girl who is shorter than her appears next to Ling... And this girl's personality is similar to Ling's! "Master, if you want to be a 'king', you can only become a 'king'..." "Master, you want to become a 'king' and always... Accompany me and my sister~"
