Chapter 309: The Heart of Flame

Looking at the boy sitting cross-legged in front of him and the Food Spirit by his side, surrounded by wisps of flame, Lu Dong couldn't help but rub his eyes.

Then, there was a moment of silence.

What the hell?

With his keen eyes, he could clearly judge that the Food Spirit in the Refining Fire Altar was absorbing the surrounding high temperature in a strange rhythm, transforming it into its own power. The originally nearly depleted spiritual power was rapidly recovering.

This was precisely the special secret technique, Capturing Fire, that had been handed down from generation to generation in the Yan Mountain Training Ground.

This secret technique was created by the ancestors of the Lu Family. It was the biggest reliance for the Lu Family when guarding this sealed active volcano from generation to generation.
