Ved learnt from Avery that cultivation had become almost impossible. The ambient essence was polluted.
Both races were working on a formation that would purify the essence around a certain area.
There was already a working model but it ability to purify essence was very slow, not to mention it need for essence stones.
This increased the value of essence stones by manifolds. For multiple reasons, cultivating without them was very dangerous.
Plus the formation can also be used around cities to reduce the numbers of dark particles.
They learnt the formation cannot fully get rid of the dark particles but it can reduce them by a large margin.
So Ved's idea was earning essence stones, he already owned multiple essence stone mines.
The biggest being the mountain below him, it not only had essence stones but liquid essence as well which was even more potent.
