"As for the fire vein~~"
Yang Zhenshan carefully sensed it, then his figure flickered, arriving in the mountains and forests to the east of the Spirit Source Land.
This place was almost at the edge of the Spirit Source Land, and there weren't even any plants growing on the mountain, yet Yang Zhenshan could clearly feel that the fire spiritual energy here was several times denser than elsewhere.
He stood on the hillside, looking at the half of the mountain peak, lost in thought.
"Is this a volcano? Perhaps not, it might just be an underground fire vein."
"Then how should one extract the earth fire?"
He thought for a moment, took out a seed of the Azure Dragon Vine, and then tossed it onto the ground.
In the next instant, the Azure Dragon Vine began to grow rapidly, under his control it didn't grow on the surface, but burrowed underground.
The growing vine made the rocks underground emit a dull sound under its pressure.
