From the very beginning, Tang Ye felt that something was off when he saw the explosion of dark, evil, and bloody black-red aura from Wen Zhongyuan. This power seemed familiar to him, yet he couldn't fully grasp it. It wasn't until Wen Zhongyuan's power grew increasingly fierce that he recalled, this aura belonged to the Blood Demon he had encountered in the Illusory Realm.
The aura of the Blood Demon was something Tang Ye had only experienced in the Illusory Realm, so his understanding of it wasn't deep. However, if he saw it with his own eyes, he could still recognize it. Now that Wen Zhongyuan was emanating a black-red aura, Tang Ye was certain of it. He was extremely surprised by this revelation, so much so that it felt somewhat surreal.
