"It only takes four thousand Spirit Crystals to get nearly seven hundred per day — I should have done this sooner..." Lin Yun lamented.
However, he was merely making a casual comment — the device specialized in absorbing and refining Spiritual Energy, along with the Spirituality, had only cost him four thousand Spirit Crystals, thanks to Star Blue generously selling them to him at a low price.
Without Star Blue's help, the cost would have been much higher.
In addition, the one thousand and five hundred Spirit Crystals that Star Blue had advanced him for his Spirituality was merely the price difference, which allowed him to gain seven hundred Spirit Crystals. All in all, he might not have had enough even if he had spent six thousand Spirit Crystals.
Before this, accumulating six thousand Spirit Crystals would not have been easy.
Also, if he had chosen that path, the Cosmic Trading System wouldn't have absorbed as much Spiritual Energy as it did.
