The essence of "Infernal Hell" is another vast, cold, and desolate Otherworld.
After the Dragon Slayer battle, Yi Qingyan classified the offensive use of her Cursing Prohibition into two categories:
First, the "Space Slash" she had been using from the very start. Its essence is a rift formed when the Other Dimension intersects with the real world, and she can freely manipulate the size of this rift to achieve an "Omnislash" effect.
The second is "Dimension Devouring," which directly manipulates the Other Dimension to invade reality. This power does not act on material objects but on the entire space, so even intangible souls or entities with other physical immune forms would be swept in and vanish from reality.
What Wan Dugu encountered was the latter.
He dispersed himself, expanding his spiritual sense and interference range to the extreme; yet Yi Qingyan seized the opportunity, and all these fragments were engulfed by the void opening blooming in the sky.
