A day later, Li Yao, Long Yangjun, and Li Jialing, leading the brawny soldiers that had been carefully selected, climbed through the zigzagging cracks and the unknown, abandoned wells, ascending for several thousand meters on the giant excavators that were similar to the earthly dragon. Finally, they approached the altitude where the "Great Iron Plants" was at.

The five thousand meters below the ground was generally a boundary. The views and the purposes of the towns up and down were entirely different.
The towns established above the five-thousand-meter line were mainly to accommodate the excessive population on the ground and to expand the living space of humans. The towns below the five-thousand-meter line, on the other hand, were almost all created because of the discovery of a certain resource.
