The formation was set up quickly. The whirlwind was now under Zhao Hai's control. Not only could the formation turn the energy in the whirlwind into crystals, but it could also control the energy in the whirlwind. If the energy in the whirlwind was too high, the formation would absorb the energy faster when it was about to explode. This was equivalent to having a crystal making machine. Of course, the crystals made this way were not very high quality, only around third-grade crystals. It might only be equivalent to a first-grade crystal stone, which was already very good.
After that, Zhao Hai went underground and set up a natural energy formation. With the formation, the place would become a place where the plants would mature in a few days. This was what Zhao Hai needed.
