A gigantic pyramid stood at the end of the sea of sand, like an ancient colossal beast that had slept for tens of millions of years.
The afterglow of the setting sun spilled across the yellow-brown stone walls, casting long shadows and making it seem even more magnificent and desolate.
Everyone stood at the foot of the pyramid, craning their necks until they ached, yet they still could not see the top.
"My God..."
Leorio swallowed, his voice trembling.
"Isn't this way too huge?!"
"It's more than ten times taller than the tallest building in our town!"
The red lights in Genos's eyes flashed frantically as scan data refreshed without pause.
"Main structure height: 812 meters."
"Underground extension depth: estimated at 1,200 meters."
"Interior divided into seventeen catacomb levels. Structure extremely complex. Numerous unknown trap responses detected."
Seventeen catacomb levels?
Everyone froze for a moment.
Eight hundred meters aboveground, and another twelve hundred meters hidden below?
This was not a tower at all. It was practically an underground city buried in the sand!
"Where's the entrance?"
Gon looked around, overflowing with curiosity.
"Let's get in and find the cola!"
Saitama was even more impatient. His nose twitched, and following that faint sweet scent, he walked straight to the stone wall at the front of the Pyramid.
The enormous stone wall was covered in dense ancient patterns, crooked and twisted, impossible for anyone to understand.
At the center stood two gigantic stone doors over ten meters tall, fitted tightly together without even a handle.
"These doors are huge..." Leorio scratched his head. "How do we open them? There isn't some kind of mechanism, is there?"
Saitama said nothing.
He stepped forward and pressed a hand against the stone doors.
With a gentle push.
Rumble—!
A dull thunderous sound came from behind
