Resistance Fortress

This resistance army fortress was built on an abandoned air-raid shelter. This air-raid shelter is a huge artificially excavated pit. The fortress was built on the cliff wall according to the situation, forming a natural pattern that is easy to defend and difficult to attack. The deep pit is rich in special ores to form a magnetic field, which is difficult to find with ordinary detection equipment, making it an important command post and gathering center for the Resistance.
