Li Shiming arrived at the edge of the pool, where he discovered the source of the Spiritual Energy, the pool was bubbling from within.
Bubbles brought forth pure Spiritual Energy, suggesting that there was a spiritual vein beneath the pool.
As this spiritual vein had not been discovered by the Sky Sea Sect, he had no idea where it originated from.
However, considering the distance from the main island of Sky Sea Sect, it was very likely a new branch of the main spiritual vein.
Perhaps there were two branches leading toward Eagle Beak Island, one being the exposed inferior spiritual vein, and the other a branch suppressed underground and connected to this sealed space.
Normally, cultivators excavating their caves wouldn't dig too deep on an island, so it was only because Li Shiming had different motives and the need for more that he accidentally uncovered the passageway to the underground space.
