Journey to the Immortal Mountain

Li Su's brow furrowed slightly. These people's souls were murky beyond measure, like conglomerations of desire, filled with chaos.

These three fellows were clearly not very old, and their cultivation was ordinary, yet the aura of their souls was abnormally ancient—so old it seemed to have gone sour.

With a slight movement of thought, Li Su opened the Ghost Domain beneath his feet and drew the three souls inside.

Though they were defective goods, their souls contained an immense quantity of Dao essence. There was quite a lot of it; after washing it clean, he could use it himself.

Not only that, but through the three men's souls, he finally understood why they had come looking for him.

After outsiders entered the Mythical Realm, they needed vast amounts of Dao essence to replenish themselves and restore their flawed Dao essence to normal.

The higher their realm, the greater their demand for Dao essence.

Although the Mythical Realm possessed an endless abundance of Dao essence, large-scale consumption would still cause fluctuations to a certain extent.

Take Li Su, for example. At present, he could extract nearly a hundred cubic units of Dao essence from his surroundings every second. The disturbance was far from small.

In order to capture outsiders, seize their bodies, or devour their flesh and blood, the organizations of this world had created an array disk capable of monitoring the flow of Dao essence throughout the Mythical Realm.

When these three passed through this area, they triggered the array disk. That was why they had come charging straight at him.

Li Su's luck was quite good. The few who had come this time were merely small fry. By the standards of the Mythical Realm, they were at Foundation Establishment.

Roughly equivalent to the Mana Realm.
