The entrance to the Dragon Ancient Realm was a patch of black clouds floating in the Void.
Li Ping'an didn't dare to claim to be widely knowledgeable, but he had seen quite a bit and by now understood exactly where he was.
The edge of heaven and earth.
This was a corner of the Vast Wilderness Heaven and Earth, where looking back one could see faint patches of light, the reflected light and shadow of numerous small worlds.
Behind the black clouds lay a barrier as thin as an "egg membrane."
This barrier had formed during the Creation of Heaven and Earth and was considered the boundary between the Primordial World and the Chaos Sea. It allowed the Creatures of the Primordial World to pass from the inside out but prevented all tangible and intangible things from the Chaos Sea from entering the Primordial World.
Under normal circumstances, the only route from the Chaos Sea into the Primordial World was through the Xuan Capital City, guarded by the Great Mage.
