Underground City

Introduction to the story of "Geoline" In order to end the dilemma of urban disorderly expansion encroaching on cultivated land and high energy consumption, China has launched ambitious land contour projects. People have created shallow underground spaces all over the plains and dug three-dimensional tunnel networks. All main roads, factories, logistics, and office buildings have been moved underground, and the ground contours are connected to each other through tunnels; motor vehicle roads are no longer paved on the surface, and only slow walking trails remain. Large areas of land have been restored to farmland, forests, and scattered low-rise residential buildings, becoming homes for people to live in peace and experience nature. The underground relies on the ground to achieve constant temperature and humidity all year round, significantly reducing heating and cooling consumption. The grand project attracts countless participants: shield engineers, tunnel inspection workers, planners and designers, business operators, grassroots operation and maintenance personnel, ordinary commuters... Everyone stands in their own position and holds completely different views on the terrain model. Some people firmly believe that underground space is the future of mankind; some are worried about the geological hazards of tunnels and are wary that long-term isolation will change people's spiritual perception; companies are demanding the opening of surface freight channels and continue to compete with ecological protection red lines. The overseas team imagined that this system could be promoted globally, but the builders clearly understood that the ocean formed a natural barrier and would be difficult to replicate outside of contiguous continents. There is no doomsday crisis or natural disaster. This is just an experiment in reshaping the country after mankind's active reflection. The shield tunnels deep in the rock formation day and night, weaving an endless underground network; the wheat waves above the ground rise and fall with the wind. The hustle and bustle has returned to the ground, and the sunny and fertile soil remains in the world. However, this grand construction spanning generations has many hidden mysteries that no one can answer for the time being.
