But even so, Lei Dong had still reaped a great deal this time. In just half a month, he had raised the Evil Ghost Banner's quality to the speed of a top-grade flying spirit artifact, though it had cost him 1.2 million Spirit Stones. Still, after the thirteen Overlord Fish were fully processed, Lei Dong's share of the Spirit Stones should exceed what he had spent. It was worth it.
