Sticky green water from the large lake shot up into the sky. Upon closer inspection, broken crystals could be seen in the water. This happened when the spiritual energy had been highly suppressed.
The lake was formed by the fourth hall master's Spiritual Energy Essence. Even the ocean came about because of the lake.
Under normal circumstances, even a martial artist with the strength of a Grade Nine Sovereign would not dare to absorb the Spiritual Energy Essence. This was due to the powerful spiritual energy that had been condensed by the Earthly Sovereign. Once it entered the body, it might take over the body and encroach on the martial artist's spiritual energy. Thus, it would not be a worthwhile endeavor.
Although the Grade Nine Sovereigns were fearful of the Spiritual Energy Essence, they went ahead and kept it in special containers.
