This wasn't the first time Michael had encountered an underground spiritual vein.
The Heavenly Flame Dragon Vein and the Starwood Spirit Vein were incomparable to the spiritual vein of Penglai Island. However, it was his first time absorbing the power of a spiritual vein in this manner.
The power contained within the spiritual vein was far purer and more substantial than what Michael had imagined.
The purer the power, the easier it could be transformed into a part of his own. Coupled with the characteristics of the 'Scarlet Flame Candle Illumination Technique,' the transformation speed was astonishing.
Michael could sense his realm continuously advancing, and soon, a substantial wave of energy burst from within him.
He directly advanced from the early stages of the Divine Transformation Realm to its middle phase.
"What a pleasant surprise indeed!” Michael said, unable to hide his smile.
