In 2155, over a century after a great war, Earth lies in ruins, and humanity struggles with scarcity. A metaverse game called "天下" (Under Heaven), developed by the Chinese company Meta, is about to launch under the authorization of the Earth United Government. This game is touted as humanity's "second world," offering wealth, resources, weapons, and status. Lin Zhao, a poor, paraplegic youth from the slums, unexpectedly receives a chance to participate in the game's closed beta. Can this opportunity change his fate and allow him to restart his life? The game's background is incredibly rich, incorporating various popular IPs such as "Xiu Luo Wu Shen," "Wan Gu Di Yi Shen," "Jiu Xing Ba Ti Jue," and "Chao Ji Bing Wang." Players can experience a vast Chinese IP universe.
