The sheer scale of Anderson Strategic Air Force Base was enormous, and the variety of combat aircraft parked within was extensive. Despite that, the base was also heavily guarded. While tourists could tour the outskirts of the base, they couldn't get close to it because a wire fence separated the base from the outside. However, there was a not-so-tall hill on the perimeter of the base, and from atop the hill, one could see the distant runways of the Air Force Base. But this hill was so far from the base, ordinary people couldn't make out the details inside. Only Yan Fei, with his remarkable vision, could clearly see the US military jets parked on the distant runways.
