I Want to Return to the Immortal World and Become the Immortal Emperor

I'm already invincible. What's wrong with living a leisurely life by exploring secret realms in the fairy world and hunting for treasures? What, after encountering a rare crack in the rules of time and space, only a weak immortal soul was left and was swept into the mortal world? Wait, where is the spatial treasure house I hide in the Immortal Soul? It's still there, now I feel relieved. Oops, the immortal soul is unstable and about to be dispersed. Let's go find the most powerful family and be reincarnated first. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
