i've read novels like Library of Heaven Path, Strongest System, Gourmet of Another World. Basically, what I'm asking for is where mc has systems. Thanks for the suggestion!
https://www.novelupdates.com/series/hedonist-sovereign/ MC is a useless young master that gets stuck with a system that forces quests down his throat (most involving a women) and gives him access to cultivation techniques in a modern setting. Lots of young master vs. young master violence.
If you want to read Hedonist Sovereign. Power off your brain. It's one of the disappointing novel I once really liked.. it quickly became nonsense and out of common sense. I guess you would say that having a gaming system is already nonsense.. but seriously. That does not stop a story to be a little realistic..
It's difficult to find an actual list of game system novels, game elements tag or level system tags don't really help. (A lot are taken by qidian anyways) Ultimate Scheming System Everyone Else is a Returnee Neet Receives a Dating Sim System The Strongest System MMORPG: Martial Gamer Shadow Hack Dimensional Sovereign (Barely) Tensei Shitara Slime Datta Ken Breakers Reincarnator Sovereign of Judgement Re:Monster (latest chapters are on the wikia and are SERIOUSLY rough) These are some of the ones I've read in search of this exact thing.
