"You're crazy!" Old Lu rolled his eyes at Little Lu.
After looking outside the door and then inside the hall, Old Lu walked out of the hall and walked back in, repeating this several times.
"I know what's wrong!" Old Lu suddenly said, "The sense of space! The sense of space is wrong! It's very inconsistent! Follow me! Look!"
From the outside, the main hall is a rectangle, less than twice as long as it is wide. From the inside, it is an inner court with a length-to-width ratio of 1:3.
The outside length is the size of seven exterior door openings, but the inside is only about the length of six door openings.
"And these floor tiles..." Old Lu pointed to the seams at both ends.
The construction of mosques has always been the work of mathematical genius! While the floor tiles could have been laid in a completely standardized manner, this temple has a structure with half bricks at both ends.
"What baseline are they aiming at?" Old Lu had a key question.
"You mean, there's something strange going on underground?" Xiao Lu seemed to understand.
"Not only underground here, but also in that circle of walls and even in the doorways of those walls, there seems to be something strange!" Lu Guansheng was very sure.
"There's no point in guessing. Why don't we open the space-time gate and take a look?" Xiao Lu suggested.
"Don't be anxious! Have you forgotten that there might be a mechanism? If the space-time gate breaks the balance of the mechanism, it will be troublesome!" Old Lu shook his head.
At this point, Lao Lu opened his backpack, took out his geological resonance detector, and began scanning the ground. A three-dimensional hologram gradually took shape.
Sitting in the center of the dimly lit atrium, Lao Lu turned on the laser projector.
Sure enough, the ground was hollow, and each courtyard was made up of nine cylindrical cellars.
"Look, none of these cylindrical walls have the resonance curves of adhesives." Old Lu pointed at the circles. "All the bricks should be movable. I guess that's the mechanism."
"What activates these mechanisms?" Xiao Lu turned the three-dimensional image and studied it.
"Look here!" Old Lu pointed below the floor tiles and above the beams. "The corners of these beams are all inverted cones. If I'm guessing correctly, that should be the pressure mechanism.
"Pressure mechanism?" Xiao Lu observed the structure carefully.
Each of these cylinders has a M-shaped beam on top, and the center of the beam is exactly opposite the midpoint of a floor tile.
If someone were digging, removing that tile would not affect the balance, but if they continued to move any of the remaining eight tiles, the beam would tilt.
But if all of them are removed at the same time, gravity will reduce the pressure and activate the mechanism.
