The use of soul crystals had been a mess from the very beginning. Soul crystals were of great use to all foreign races, and their source was few. They could be said to be precious. This time around, there were 28 of them, and the harvest from the dozen of them was only fifty soul crystals. If even a Saint realm expert was of great help, then it would be unreasonable for Dong Li to use all 10 of them. One should be enough for a rank like Dong Li to use for a long time, which was more precious. Otherwise, 50 soul crystals would be lost in a single breath for a rank 9 soul power at rank 8.
