[Global Awakening] [Class Evolution] [Rule-Based Superpowers] [Myriad Worlds Instances] In the fifteenth year of the Global Apocalypse, secret realms descended, and everyone awakened a class at the age of eighteen. Lin Yuan became the only F-rank civilian-class gatekeeper in his entire school. Everyone thought his future was ruined, but only he could see his true class name: Realm Gate Administrator. While others grind monsters to level up, he issues calamities a "No Entry" order. While others fight over secret realms, he takes control of every gate in an entire city. When civilizations from other worlds knock on Earth's door, Lin Yuan discovers that beyond the gates lie not only monsters, but also deleted worlds and the oldest secret of the class System. A gate can be opened, and it can be closed. As for who gets in, this gate is under my control.
