Lu Chao's keen senses told him that the complete magic crystal contained a rich supply of energy, comparable to that of an energy mineral essence.
This was undoubtedly a significant gain, equivalent to obtaining two portions of the mineral essence.

At this thought, a glint appeared in Lu Chao's eyes as he instinctively began to review the day's events.
