On a neon rainy night, data fortune teller Gu Sanyao stumbles upon the secret of the Tianshu Group's "Stargazer Project" through an encrypted data block - the "fragment outside the wall" that can swallow sight. Being hunted by the purge force, he formed an escape team with the orphan Aqi, the exile Lao Scar and others. Following the clues left by Aqi's father, he uncovered the truth about the algorithmic world behind the fragments. From the Rust Belt to the underground experimental center, from the virtual world to the deep-sea island, they fight against the greedy chaebols, weird deep divers and out-of-control deep-sea creatures, and guard the balance of the two worlds in the choice between destruction and coexistence.
