Yang Xiao recalled the Purple Crystal Stones mined on Purple Origin Star in the past. Those stones were purple and contained powerful Evolution Energy. When ground into powder and sprinkled into lake water, they could enhance the Evolution Energy of the water.
Additionally, Purple Crystal Stone is the main raw material for manufacturing Genetic Potions on Witch Star.
This suggests that the Evolution Crystals here have a similar nature to Purple Crystal Stones. However, the Evolution Crystals here contain Evolution Energy that is dozens or even hundreds of times stronger.
Yang Xiao, who had mined on Purple Origin Star for years, was well aware of the uses of these crystal stones.
