World view: dual time and space parallel. The modern era is a peaceful China with prosperous science and technology and crazy infrastructure; the past was a critical China with the outbreak of the all-out Anti-Japanese War in 1937, weak industry, and broken mountains and rivers.
Key rules: The system binds bloodline coordinates. The modern protagonist is responsible for blueprint design and national destiny charging. The great grandfather in 1937 is responsible for confirming the coordinates and receiving construction. The construction process cannot be witnessed by ordinary people in past time and space, and reasonable bunkers or camouflage will be automatically generated after completion.
