He was once the Chinese God of War codenamed "Zhulong", but now he has become an ordinary security guard at Nanjiang University. The task is to guard the aura nodes deep in the campus and "observe" the student Ye Fan who was ridiculed as a loser. Lin Feng wanted to just lie down, until his spiritual energy revived, a crack in the alien world opened in the playground, and all forces swarmed in, just to snatch the "key" in Ye Fan's body that was related to the survival of the world. Looking at the panic-stricken campus, Lin Feng sighed and took out the rusty standard sword from the guard room. "Listen up," he stood in front of all the students, pointing the tip of his sword diagonally at the ground, "This gate belongs to me, and this school belongs to me. If you want to touch people in my school - ask me, the gatekeeper, first." From then on, the strongest God of War hid in the gate. He protected not only the key boy, but also the first hope of an era.
