"Master, if you can completely refine the energy within this Thunderfire Wood into your True Essence Sea, your cultivation level will surely skyrocket by several tiers," suggested the Celestial Fire infant. It had no interest in the Thunderfire Wood itself, as it was a pure fire-attributed spirit, and the thunder and wood attributes of the Thunderfire Wood would be wasted on it. Besides, Terra Su had already prepared plenty of fire-attributed rare treasures for it.

Terra Su nodded and said, "Little Fire, continue your cultivation."

The Celestial Fire infant resumed its cultivation state, while Terra Su held the Thunderfire Wood in his hand, his soul power probing into it, feeling the surging energy within.

The Thunderfire Wood contained energies of thunder, fire, and wood attributes.
