Kaiju Jiu You Wang Zhe Zhanghao

A sudden and catastrophic crisis plunges Earth into the mysterious OL era, reshaping human civilization under the influence of an unknown force. Every person on the planet is instantly reduced to a level-one novice, stripped of their former advantages and thrust into a brutal new reality where survival depends entirely on strength. In this unforgiving, cutthroat world, humanity must fight tooth and nail just to endure another day. Among those struggling to survive is Ye Hao, an ordinary high school student who has managed to push himself only to level three—a meager achievement in a landscape dominated by ruthless predators. Pushed to his absolute limits, he finds himself cornered and on the brink of death. However, at the very moment all hope seems lost, he accidentally triggers a hidden mechanism known as the King's Account Upgrade System. This unexpected awakening grants him a unique path forward in a world governed by levels and power. Armed with this newfound advantage, Ye Hao must navigate the deadly challenges of the OL era, transforming from a desperate survivor into a contender for ultimate supremacy. Whether he can truly rise to become the strongest king remains to be seen.
