Am I the Only One Without a System?

On the planet Blue Star lies a continent called the Glazed Continent. In this era, everyone on the continent has a System, except for the protagonist, Ming Yueye. With no cheat to help him, he's crushed by the competition and finds studying a struggle. To ordinary people, a powerful System is one that lets its user complete quests with ease. Completing quests makes you stronger. No one knows where the Systems came from. The outside forces have cheats of their own, too, and they occasionally attack, undermining social fairness and plunging society into chaos. So how can Ming Yueye survive without a System?
