Yeah for real, instead of "unlike other transmigrators" it should be more "exactly like every other transmigrator MC to have been written in the past 5 years" lol.

I only saw 4, the rest of them don't even finish saying that word and are already showing off to the world and slapping everyone in the face

Are you sure about that m8? They say "low-key" but really they are only low-key for the first chapter and then the face slapping and needlessly revealing abilities begins. Also, when the MC thinks he is intelligent and calculating is hilarious because he is a complete and utter dumbass. Never fear though, because the villains are even dumber! The only advantage is the fact that everyone is always watching (why is there always an audience to watch the MC fight if it is in a super top-secret facility for training/in the middle of a forbidden area, but there are still so many ppl there?) and everyone knows some random obscure skill. I mean seriously, they say "OMG! The Nine Yang Pure Fire art that was lost some billion trillion quadrillion years ago used by the Fire Lord of Purgatory (which won't get mentioned ever again) has been used here. It states that if you cultivate this scripture to the twelfth layer, you can receive power equivalent to a golden core stage cultivator!"
