Programmer's World

In 2050, humans will realize "Digital Reality" for the first time - through brain-computer interface, human thinking can directly interact with computer systems. Code is no longer written on the screen, but "thought" out. An algorithm can control physical equipment, a line of instructions can affect financial networks, and a system can reconstruct a city's infrastructure. Thirty years later, human civilization has been reshaped. The world is ruled by five major city-states: **Central City, Tiangong City, Abyss City, Border City, and Ruined City**. City-states are separated by "digital barriers" - huge firewalls of code that ordinary people cannot cross. Travel requires "Code Gate" permissions. In this world, programming is not a skill, but a power. People who can't program are not "ordinary people", they are "non-existent people".
