As they stepped onto the top of the stairs, a majestic and towering gate suddenly broke through the void, gradually revealing its form.
The giant gate was entirely dark, neither made of gold nor stone, with intricate and mysterious divine and demonic patterns engraved all over the door panels, interwoven with traces of ancient years, exuding a sense of eternal and majestic pressure.
The door was tightly closed, yet an endless, grand aura slowly seeped out from the cracks, causing the entire valley to tremble slightly.
"Boom..."
A deep and heavy rumbling echoed through the valley as the ancient door, silent for ages, slowly opened to both sides.
At the moment the door opened, a boundless and pure terrifying power burst forth.
This power seemed to carry the endless accumulation of years and origin power, transforming into a vast torrent that surged out instantly.
