Lu Sheng took a deep breath, ready to explain everything in detail to Li Muchen.
"You just heard Ning Yu calling me Ah Qiang," Lu Sheng said, "Actually, I was originally a rose in the deepest depths of Hell, and transformed into a demon after absorbing enough Evil Qi, then I could come to the Human Realm and attach to a human body. And Ning Yu... is kind of like a Pearl Clam Spirit."
"As long as there is a human body in the Human Realm that matches their soul, demons can attach to humans. It can be either living or dead people, but it's best if it's a dead body that just passed away. Because if it's a living person, it might cause struggles for control over the body."
"So... baby," Li Muchen asked, "did you enter Lu Sheng's body right after she had just passed away?"
"Yes, but by then my soul was wandering in the world for a long time and was very weak. I needed to replenish my Soul Power. That's when I met you."
