Become Emperor from a Ghost Baby

A female ghost was pregnant for five hundred years. A lightning strike opened the coffin and gave birth to a child. Li Sanwen happened to travel through time. "So, I'll be five hundred years old when I'm born?" "A five-hundred-year-old baby is certainly smart." "I can use your spells at a glance, and I can copy your magic weapons at a glance. Why, because my understanding is incredible... Come, come, let's all be friends. We have friends all over the world." All the victims: "God, please accept this monster."
