Chapter 124: Test (2)

Old Kai is aware of how taxing this would be for an average creature, much more for a newborn baby. This is why he is supplementing Ether's energy with Arcane. He is using Arcane from the world itself and not his to ensure the purity of energy that flows on Ether. Due to his actions, the previously dark cave lit up. It showcased an array of beautiful Arcane Crystals that are embedded all throughout the cave. The old man did not bring Ether in this cave out of a whim. This is the safest place with the densest concentration of Arcane he knows of.
