The so-called Saint Heart is merely a general term. In reality, it doesn't genuinely exist as an entity; rather, it is a manifestation of a Saint's Laws and Dao.
However, what did Nuwa see? Ye Xuan actually extracted her Saint Heart from within her and materialized her Laws and Dao. This terrified Nuwa to the extreme.
Puh!
With the extraction of the Saint Heart, Nuwa's aura immediately wilted, blood constantly oozed from the corners of her mouth, even her pupils were gradually dilating, and a faint aura of death was spreading outward.
As this scene unfolded, the starry sky fell into silent desolation. The four Saints halted their assault on the Starry Sky Array, unable to believe what they were witnessing.
"What a magnificent Glazed Saint Heart, such pure power!"
Within the Starry Sky Array, Ye Xuan's eyes reflected intense infatuation, as if he were admiring an unparalleled treasure, uttering words of praise.
"Give me back my Saint Heart!"
