Han Yi had wandered this mysterious Realm for seven years, during which he had traversed its entirety, exploring the underground conditions wherever he went.
As he had suspected, the material beneath this Realm was metallic, and the hardness of the metal far exceeded his expectations.
Whether with ordinary Immortal Artifacts, Tao Swords, or the Feast Sacrifice Divine Axe, none could leave a mark on this metal.
He became increasingly convinced of his guess that this Realm was actually an enormous tool; it could be an unimaginable weapon, a Taoist Boat for transporting people and objects, or even a fragment of some weapon.
At this moment, each Divine Aperture World within him could transform into a world, and in the Daoist Domain, plucking some of the Divine Aperture Worlds could produce land as vast as this.
