As they walked to about the midway point, they saw a concrete partition wall stretching across the front, forcibly dividing the bunker into two sections.
In the center of the wall, a heavy double explosion-proof iron door was embedded.
The complex and intricate mechanical structure at the door lock position indicated its extremely high level of security.
"This wall serves as a natural dividing line."
Lin Chuqiao pointed to the deep space behind the door, her tone gaining a solemn weight:
"The area behind the door covers nearly a thousand square meters and is fully enclosed. No one knows what it was used for in the past, but I suspect it was likely a biochemical laboratory or ammunition depot from wartime preparations."
"I plan to install a biometric identification system at the access point, using a dual verification mode of iris and fingerprint."
