When a mysterious catastrophe suddenly strikes the planet, Earth is dragged into the terrifying OL Era, a world where humanity becomes nothing more than entertainment for an unknown higher power. Every person is assigned a level-one account, and survival now depends entirely on leveling up and becoming stronger. In this cruel new age ruled by power, the weak are quickly abandoned and eliminated.

Ye Hao, an ordinary high school student, struggles desperately just to survive. While countless geniuses rise rapidly through the ranks, he remains painfully weak, barely reaching level three. Cornered at the brink of death and believing everything is over, he unexpectedly awakens a hidden ability—the legendary Max-Level Account System.

From that moment onward, the rules of the world begin to change for him.

With access to abilities far beyond normal limits, Ye Hao starts an unbelievable rise from the bottom of society toward absolute supremacy. In a world where everyone fights to level up, he may become the one existence standing at the very peak.
