The Energy Center at the 911 Aircrew Base, with the Target Low Temperature Nuclear Fusion Energy Tower and the sunlit small building, is still there and maintained regularly by dedicated personnel.
Chen Fei, familiar with the place, found his personal belongings left in the small building, and even Boss Hanna's little wine cellar remained. Little Bird immediately fluttered happily among the lush plants in the sunlit room.
A transparent glass dome and floor-to-ceiling glass walls isolate the indoors from the outside environment. There is no lack of sunlight, air, moisture, or fertilizer, and those who maintain it put in a lot of effort. There are visible signs of careful pruning, and even the harvested fruits are made into bottles of fruit wine, separated into first-pressed and distilled, just like the time when Chen Fei and the former house owner, the Neanderthal elder Barut, lived there.
