In 2060, China is developing military nanophones. They are a high-tech marvel packed with powerful features.

Liu Gang was an elite special forces soldier who transmigrated to a parallel-world America. Now a Chinese-American and the leader of a Delta Force squad, he has a wife, Jane, who is a skilled soldier and his trusted right hand and support.

Liu Gang discovers a mysterious connection between his military nanophone and The Walking Dead: No Man's Land. Although some of the phone's functions are damaged, its crucial features still work. It can display game coordinates and activate a teleportation device, allowing him to move freely between the game world and reality.

The military nanophone recharges using light, while the game's storage vault has mutated into a mysterious black hole with unlimited capacity. It can materialize items in the real world, and Liu Gang can use real-world cash and gold bars to buy weapons from the in-game store and protect himself from enemies.
