Mo Qingxuan did not know just what Lin Fan wanted to do. Those Pill Spirits had already mentioned earlier on that this was a barrier set up by an Immortal King.
An Immortal King was someone who shared his life with the Heavens, an existence that went through eternity with the Heaven and Earth. How strong of an existence was an Immortal King? That was someone who could destroy the firmaments with just a single finger flick, and could traverse thousands of universes with just a single thought.
That was an existence who already wielded control over life and death. A single thought could create all living beings, and at the same time, a single thought could have them all annihilated.
