Upon the dark crimson earth, a stone book hovered within Li Ming's palm, his spirited vital essence continuously infused into it.
As the vital essence surged in, even more profound mysteries about the stone book poured into his heart.
Life and death, yin and yang...
Mysterious insights kept flooding into his heart, and more information about this place constantly appeared in his mind.
After the cosmic upheaval, what changed was not just the world's surface but also its inner workings.
This place, it could be understood as the world's shadow, its silhouette.
In other words, what is referred to in legends as the Netherworld.
Yet, this world didn't exist before the cosmic upheaval; after the upheaval, streams of mystic yin force and deathly aura converged, forming another world beneath the surface of this one.
In some ways, this world complements the various demons and monsters on the world's surface.
