Author honestly ruined it by allowing him to use his cheat for martial arts, goes against the initial premise imo. Also that young master needing to pay him a lot of money and to study calligraphy for living in his house is genuinely stupid, really lame justification
I have no idea why he keeps using important resources like pills, spirit stones etc in real life instead of using them in the simulation, and then just gettting the cultivation back. That is so stupid. Not to mention Mo chen attacking him many years later while Mo is Foundation and MC is 4th real QI refiner, how does it make sense for Mo chen to attack him? Obviously MC has trash opportunity if his cultivation is still at 4th level so many years later
