One thousand meters under the surface, a cave the size of two basketball courts was buried deep inside.
With the elevator descending, the light along the corner of the cave opened consecutively as it illuminated the underground space.
Around the area was soil packed tightly and rocky surfaces. Facing the elevator was the door to Fallout Shelter 027.
It is an inconquerable base.
The only entrance was blocked by a gear-shaped door 10 meters thick. The 8m thick compressive alloy steel and the 2m thick lead sandwich was enough to withstand a million tons TNT equivalent nuclear strike!
Tian Feng walked to the door of the fallout shelter, inputted his fingerprint, and opened the steel cover attached to the door. He then took a cable covered in soft lead material and attached it to his EP.
