On his wedding day, the seal inside Xiao Yi was unlocked, and from then on, he controlled the Eternal Celestial Tomb! Many of the strongest beings from all the heavens and worlds were buried within the Celestial Tomb, and Xiao Yi, who now commanded the tomb, began his life’s journey of gaining strength through grave-robbing! “You think you’re a martial arts genius? Let me dig up a Martial God’s grave and we’ll see!”“You consider yourself an alchemy expert? I’ll dig up a Medicine Saint’s grave and then we’ll talk!”“You’re the son of a divine emperor? I’ve got plenty of divine emperor graves here!”“You’re the number one scoundrel in the world? ... You win, I’m out!”

For some odd reason, I instead ended up spending my days in relaxation and bliss.
