Yang Xiao was immediately stunned upon getting out of the car; the area was vast, equivalent to three or four football fields. He looked up and saw under the spotlights, thick metal pipes as wide as tin barrels supporting the massive structure like a steel skeleton, with the building reaching at least 30 meters high.
