When Chen Xin and the survival group's friends initially designed the bunker, the ideal plan they proposed was to convert missile silos or abandoned military air raid shelters into bunkers, turning them into small communities.
However, this plan was abandoned due to policy restrictions and economic issues in Flame Country, leading everyone to build private bunkers instead.
In the initial conception, there were indeed many ideas regarding the design of the bunkers.
Some of these ideas were very practical, such as greenhouses for planting, water circulation systems, air filtration, and communication facilities, but there were also some ideas that were somewhat unrealistic yet still functional.
For instance, building a library and bringing a large number of paper books into the bunker was actually a great idea. After all, compared to electronic products, paper books could be preserved for much longer. If you take care of the books while reading, one book could last for decades.
