The cold Profound Ink Flame scorched the Spiritual Power, and under the calcination of the flame, the surging colorless Spiritual Power gradually transformed into a thicker quality.
The tempered Spiritual Qi directly converted into a small amount of pure Magical Power, returning to the meridian flow.
This is a characteristic of Spiritual Qi condensing into a higher energy level; after the colorless Spiritual Power is compressed and calcined, it turns into a stronger Magical Power, seemingly reduced in volume by several times, but the energy contained within is purer and more potent.
The Black Evil Technique that Zheng Yi cultivated was not powerful in its early stages, but when cultivated to the Ink Spirit Evil, it spontaneously condenses the Demon Fire, capable of calcining Spirit Body and Divine Soul, and refining Magical Power, which naturally goes without saying.
