The method Aksai and Yelia had jointly developed was simple but effective.
Yelia would create ethereal runic streams from the accumulated emotions in the Demon Tree, then send them to Aksai through the Myriad Worlds Painting.
The Demon Tree acted like a power source, the painting was the conduit, and Yelia served as a regulator, ensuring the energy didn't overwhelm him.
Of course, it wasn't a perfect system. The limitations were many.
Firstly, Aksai could only handle so much of the filtered intent-based energy at once. It wasn't strong enough to force a breakthrough in his current Foundation Building realm, but it still helped him stabilize his cultivation and refine his Spirit essence at a faster rate and also more effectively.
