Quietly using his Spirit Sensing technique, Su Xuan glanced over the dozens of stones in the million yuan area and already understood which one contained jade.

To put it plainly, Su Xuan was not certain that the stone definitely contained jade; however, the more Spiritual Energy a stone contained, the more certain Su Xuan was that the jade inside was of exceptional quality.

The dozen or so pieces of jade in Azure Dragon's shopping cart were meticulously selected by Su Xuan, all containing substantial Spiritual Energy, indicating that they certainly contained stones.

Su Xuan needed Spiritual Energy for cultivation, and discovering Spiritual Energy within these stones, leading to the discovery of jade, would allow him to minimize the costs of his cultivation practice.
