So I remember reading this novel where this dude is like a descendant of someone really powerful in another world and them that guy died so a little girl comes to him telling him about legacy. He then decides to make that world available as a videogame and the power used in that world is soul power so he makes soul coins and stuff. Can't remember the name
This is very very similar to The Boss Behind the Game except for the fact that the mc didn't die. Interesting. Sadly I'm poor so I'll just stick with the 70 free chapters.
