I Possessed a Demon Sovereign IPDS

Chen Luoyang is perplexed about his transmigration. After transmigrating, he possesses the body of the strongest expert in the world, the Demon Cult Master, addressed respectfully as the Demon Sovereign.
Generally, aren’t supreme experts the ones that end up with a wisp of their soul only to occupy a new body of some young, miserable low-life before embarking on a journey of revenge and making a comeback?!
Or perhaps it would be him transmigrating into a miserable youngster’s body and obtaining a cheat before embarking on the path to becoming a god?
But why does it seem like his transmigration has gone wrong?
Now I'm surrounded by big shots and I feel like I’m going to be exposed!
HELP!
