Capítulo 582: Chapter 265: Area 51_3

```

After realizing this was Area 51 of the United States, Yan Fei had an epiphany. The Upgrade Essential Items that the Auxiliary Brain had prompted weren't the items in the underground crevice but rather those within Area 51. And just as Yan Fei felt the urge to approach Area 51 to search for the Upgrade Essential Items, a sudden intense terror emerged in his heart, and this horrifying sensation stemmed from Area 51 below.

This filled Yan Fei with an extreme sense of danger. He had an intuition that if he were to enter Area 51 now in search of the Drone Upgrade Essential Items, he might very well die on the spot.
