Lin Yuan wanted to evolve the Source Sand first.
He instructed the Source Sand to change into quicksand before he fed spirit qi crystals one by one into the quicksand.
The Source Sand's power slowly increased. By the time Lin Yuan tossed the 200th spirit qi crystal into the quicksand, the Source Sand had evolved to Diamond I/Fantasy II.
A wave of sand granules kicked up from within the quicksand. These sand granules were all made of Close Guard Sand, the most active parts of the Source Sand.
Lin Yuan noticed that the Close Guard Sand had changed significantly. Previously, the Close Guard Sand was translucent. But now, the Close Guard Sand was made of transparent crystals.
These crystals did not have color, but they seemed to be able to absorb any metal-type spiritual ingredient and temper it to gain its characteristics.
Although the quicksand under Lin Yuan's control did not expand, the quicksand currents were now 1,000 times stronger.
