Swallowing the Sky to Suppress the Demon: I, the Son-In-Law, the Demon Emperor with Bloodline

I, Yun Jin, fell from the fairy world and woke up in the wasteland of Star Ruins, becoming the abandoned son-in-law of a human family. In my previous life, I was the "Xinghen Immortal Lord" in the Mighty Immortal Realm. I was besieged and killed by the emperors to protect the most precious treasure [The Heaven-Swallowing Cauldron]. In this life, my meridians are all broken, my memory is incomplete, the Su family who has married into my wife regard me as a shame, and the whole city laughs at me like an ant. However, they don't know—— The divine cauldron in my Dantian can swallow the energy of all races and analyze the secrets of the Star Ruins; The immortal magic in my memory can recast the star veins, refine weapons and elixirs, and take charge of the lost civilization. The business war assassinations in Canglan City are just an appetizer; The geniuses of the human empire are suppressing, but the ants are noisy. When I reached the top step by step, I suddenly discovered: My bloodline actually belongs to the alien race in the starry sky, the mortal enemy of the human race. Should I stand at the top of the human race and slaughter all my "comatriots"? Or should we bear the sins of alien races and tear the world apart? Or... Use the divine cauldron to swallow the sky, reset the order of all races, and become the only god lord in this Star Ruins era!
