The entire underground base was filled with excitement.
Xiang Shan stayed in the reception room, listening to the noise outside, and couldn't help but sigh: "What is going on..."
This is the underground base, which was originally a station. Directly above it is a national park in central Africa—a place that was worth visiting for its natural environment in the 21st century.
To get up from here, you have to take a long escalator.
This group of Heroes has on the basis of this station, continued to dig downwards, expanding a reliable underground base.
The depth of the base exceeds two hundred meters, at this distance, the daily activities of the base are basically undetectable by personnel on the ground. Additionally, there are Hero teams stationed on the ground, monitoring the government's activities nearby.
