Why had Ye Han been worried about this?
Because during his search for Bìtiān Divine Lord, fortuitous opportunities, and Heavenly Treasures in the Spirit Mountain Land, Ye Han had discovered that the Heaven and Earth Spiritual Energy here was growing increasingly depleted, its concentration steadily falling.
Some special Heavenly Treasures had already begun to wither. That was one consequence of the dwindling true immortal spiritual energy throughout the Great Dream Immortal Palace...
Most importantly, Ye Han reckoned that if the true immortal spiritual energy in the Great Dream Immortal Palace continued to decline, the entire palace would collapse.
His preliminary judgment was that true immortal spiritual energy powered and protected the entire Great Dream Immortal Palace. That was how it could fly out of the Heavenly Spirit Realm and travel through the Boundless Star Sea. Without enough true immortal spiritual energy to power it, how could that possibly work?
After all, the Boundless Star Sea did not have enough Heaven and Earth Spiritual Energy to replenish the Great Dream Immortal Palace, much less true immortal spiritual energy.
Every formation needed Heaven and Earth Spiritual Energy to power it. Naturally, something as enormous as the Great Dream Immortal Palace consumed a vast amount of it.
