πHello ~ According to your needs, I will recommend you a few novels with game systems. The first was "The Rise of the Overlord of Total War", followed by "I'm Watching the Vanguard","Extraordinary Contact in Online Games","Celestial Realm System","Warcraft Shop System","The Strongest System: Hegemony of the Other World", and "I'll Take Players to the Other World to Build a Territory". The plots of the above novels are all different, but in short, they are all very good! I hope you like this fairy's recommendation. Muah ~π
