Life Simulator: A Heartless Game, No Grinding or Spending

[Multiple worlds + Introverted male lead + Game-like System + No female lead in the main world + Neither angsty nor sweet, leisurely plot]

“Ordinary people make ordinary lives.” But Zhang Qi's ordinary life is accidentally disrupted by a “blockbuster” game. He has no idea where the future will lead, or whether anything needs to change at all. Maybe the only difference is that he now has a little game he can play anytime, anywhere.

[Some longer arcs are told in separate installments. After all, games need version updates too.]
