"The entire defensive line is connected by telephone lines, and the generator equipment has also been concealed. More than half of the important facilities are in underground bunkers... We have fully considered the Tang Army's strike capabilities in this regard."
Originally, they were reinforcing the existing defensive line, so many areas were already there before. For instance, some tunnels or bunkers within the mountains.
However, there are some things that need adjustment. The most critical ones are actually the so-called energy sources and ammunition storage areas. These places are the most vulnerable on a defensive line, so they often need to be heavily protected.
The defensive line previously built by the Poplar Empire was aimed at Dwarves, so they didn't need to design these areas to be too concealed. To address heat dissipation and discharge issues, these power plants and water supply facilities were often built on the surface, which made them extremely vulnerable.
