Life Simulator: a Cool Game That Doesn't Bother You

[Multiple worlds + introverted male protagonist + the system is game-oriented + the main world has no female protagonist + neither sadistic nor sweet, the plot is bland] "Ordinary life creates ordinary people", but Zhang Qi's ordinary life was accidentally disrupted by a "hot" game. He didn't know where the future would go, or there was no need to change at all. Maybe the only change was the addition of a small game that could be played anytime, anywhere. [Some long plots are narrated in segments. After all, the game needs to be updated.]
