Ren Qing had no idea how the matter with the Mud Association would unfold. In any case, he received the payment for the mission the very next day.
He had thought it would be as Huang Ziwang said—the reward delivered by a Nether Crow—but instead, Mu Yi arrived.
This was mainly because Song Zongwu was temporarily occupied and couldn't get away, so he had asked Mu Yi to give Ren Qing the details about the Blood Crystals.
This showed that Song Zongwu was still keeping an eye on Ren Qing.
After Mu Yi's explanation, Ren Qing understood why the Forbidden Soldier Hall used Blood Crystals as currency.
First of all, they were extremely convenient to carry.
When exposed to high temperatures, Blood Crystals would liquefy and merge.
The volume of the merged Blood Crystal wouldn't change at all; only its color and weight would increase.
Ren Qing cleaved a Blood Crystal in half. The broken pieces quickly reformed into droplets, and the total weight remained unchanged.
