The Ultimate Family: So You’re the Flame Envoy?!

I transmigrate into The Ultimate Family and become Xiong Ge's second son. But an expert physician from an ancient tomb diagnoses me as a child with a demonic ability constitution. To cleanse the demonic nature from my body, I'm sent to the ancient tomb physician. I don't see the light of day again until Xia Tian turns eighteen and my abilities grow too powerful for quacks to suppress!
