Why does Lin Yuan know about this mausoleum?
It's because of the beast-skin map he obtained; even other Chaos Great Saints, though knowing this universe was created by Emperor Xuan, wouldn't be aware of the mausoleum's existence.
The beast-skin map... was placed inside a golden box, remaining unopened through countless Cosmic Eras.
Lin Yuan could open the box and obtain the map only by relying on the Xuanhuang Seal deep in his soul.
"Xuanhuang Seal?"
Lin Yuan appeared contemplative.
He began releasing the aura of the Xuanhuang Seal from his soul.
Buzz buzz buzz!
As the aura of the Xuanhuang Seal spread, like ripples on a water surface, the spacetime in front of Lin Yuan rippled and a majestic palace emerged.
This majestic palace, when it first appeared, seemed like a flower in a mirror, a moon in the water, utterly unreal, but as time faded, the illusion peeled away, revealing startling reality.
"Such a mastery of spacetime..."
