Ice Mirror Soul Threshold, at the end...
The biting ice wind was like clusters of dark blue phantoms, centered on the leaks in the Sea of Suffering, dragging long wind tails swirling incessantly, emitting eerie sounds like ghostly cries and mournful howls echoing around graves.
At the center of the leak was a black heart embedded.
The heart beat powerfully in mid-air, "thump thump," producing irregular loud sounds caused by the Netherworld Corpse Demon struggling and impacting inside.
Back then, when Song Yan reached the end of Changwang's Soul Threshold, he needed to use the Myriad Souls Banner to barely hold on, and that was only when the Demon Monk was distracted dealing with others.
A fully exerted Demon Monk could penetrate excess Cause and Effect defenses with the sound of "Celestial Demon Enchantment," reaching the essence directly and trapping one in the Illusion Realm, unless there was an Evil Treasure to resist.
