Forgotten Title BL Novel, pls help

So I happen to have lots of time right now, and something keeps popping up in my mind.

I forgot what novel it was and of course, what arc it was.

So the scene I remember was our mc in a business-centered world. And then, the mc is video calling our ML and "accidentally" flashed some skin to ML.

I think the original main character of that arc was a family of ML, and this nephew (i think?) will be defeated by our MC in a game of stocks or something.

So that's all I remember.

Pls help me, I wanna reread that arc. Thanks!

 

seems to be the first arc of
Quickly wear the face of Devil

 

I'll read it now. Don't know how many times I've read this novel ahahahhahahah. But I seem to always get it mixed up with other world hopping bl novels, the MCs' personalities are quite similar.

 

I also think it's QWTFD... MC owned Noah tech or something like that I think?? And he against the half-brother protag there.
