After collecting so many precious diamonds, Yan Fei immediately became interested in the various crystal formations on the ground. He began continuously storing these crystals into the mini-production workshop in the Universal Space, hoping to extract valuable chemical elements from them. However, to Yan Fei's disappointment, although the crystals still looked colorful and beautiful, they were actually not valuable at all and not worth collecting.
The ground space in this Underground Space was vast, and it was impossible for Yan Fei to survey the entire area by himself. Soon, he gave up the inefficient method of searching on his own and activated the Drone Quantum Radar hovering above his head. By consuming a large number of Energy Points, he conducted a wide-ranging and detailed scan of the underground conditions, deciding whether to collect these items based on the elemental distribution scanned.
