As Ye Zhen set foot on Ancient Demon Island, he was greeted by the more profound fluctuations of Heaven and Earth Primordial Energy, accompanied by the scent of the earth.
The density of the Heaven and Earth Primordial Energy exceeded that found in the High Grade Spirit Veins within the True Spirit Domain, lying somewhere between the concentration found in High Grade Spirit Veins and Supreme Spirit Veins.
No wonder those martial artists with powerful cultivation love to come to the Outer Domain Dead Sea to train; just this dense Heaven and Earth Primordial Energy is worth it.
And this was merely the peripheral area of Ancient Demon Island; if one were to enter the gathering place of earth veins on the island, the density of Heaven and Earth Primordial Energy might be even stronger than that found in the Supreme Spirit Veins within the True Spirit Domain.
