Inside the Ruin of Time...
After Ye Jieye's soul was violently extracted from his vessel, his original body initiated a defense mechanism that instantly called upon its own soul. The original body was located in the Dungeon of the Ruins of Time. With a strong rune from the dungeon shielding it, Ye Jieye's spirit flew toward the direction of the shut entrance. The barrier and seal at the entrance were actually destroyed by his spirit returning to the dungeon.
His soul was so strong that it burned down the seal and was destroyed just by stepping on it. His soul began to gravitate towards the ruins of time the instant he unintentionally cracked the seal. Ye Jieye could have struggled, but he chose to let it alone, believing that this force would return him to his new vessel in an instant.
