Lin Yi lay on the ground and put his ears close to the ground.

"Yohe, Lao Lin, do you still have this ability? Ears downwind! ”

Lin Yi made a silent gesture towards Wang Qiang, and Wang Qiang immediately closed his mouth, and wanted to lie on the ground like him.

But his big belly was on it, and he couldn't go down, so he could only squat down and watch Lin Yi operate.

After about ten seconds, Lin Yi suddenly snapped his fingers.

"I see!"

The whole person jumped up from the ground and jumped onto the cistern in a few steps.

"What do you know?"

Wang Qiang got up from the ground and asked.

Lin Yi still didn't answer, jumped into the reservoir again, and stepped on the bottom of the pool a few times.

The yellow mud in the pool showed signs of shaking up and down, and bubbles came out from time to time.

"Advisor Lin, do you suspect there is something wrong with the bottom of this pool?"

Bai Lu also saw some clues.

Lin Yi nodded, stood on the edge of the cistern, and looked around.

"Remember when I first said that if you want to completely crack the mechanism, you have to find its energy supply device?"

"Well, remember, didn't everyone say it at the time, I thought this matter was in charge of Lao Tzu, but I didn't expect this matter to be in charge of Newton."

Wang Qiang said on the side.

"When I saw that huge bronze mechanism just now, I was still thinking about this question, until the 'small third layer' you mentioned just now made me suddenly open my mouth. Look! ”

Lin Yi half-squatted and raised his thumb and gestured a few times with the surrounding granite walls.

"The surrounding terrain is high, and the terrain here is low, what does it mean?"

"Does it mean that the ancients also liked to play slippery?"

Wang Qiang replied with a serious face.

"Fuck your uncle! Let's get serious! ”

Lin Yi replied mercilessly.

"Does it mean that this depression has the possibility of collecting water?"

Bai Lu replied in an inquiring tone.

"That's right! That's what it means! It is likely that this was a granite quarry at the time, and this man-made depression was the dock where they transported the granite stones. ”

"The docks? Lao Lin, are you alright? We're underground, and you're telling me it's a dock? How did the ancients transport stone? Do you use Gundam? ”

Wang Qiang ruthlessly turned on the spit mode.

Lin Yi didn't answer, and pointed directly to his feet.

"There must be an underground river underneath this reservoir."

Hearing him say the dark river, the archaeologists who gathered in front of the glazed wall all came up.

Because they clearly remember that the last time Du Ping was in an avalanche accident, he was found in an underground river.

Academician Zhou took his assistants and students to carefully observe the surrounding terrain, and after sampling and on-site analysis of the soil, they also came to the same conclusion.

"Comrade Kobayashi's guess is not wrong! The bottom of these granite walls does have traces of being soaked in water after the water level has risen. ”

The remaining members of the surrounding archaeological team once again cast their eyes of approval and adoration at Lin Yi.

"It's just that I still don't understand what you said about this is the 'dock'."

Lin Yi smiled, pointed to his feet and said:

"I've been wondering where the power to run these mechanisms comes from, and when I got here, I understood, it's water!

At the beginning of spring, when the snow melts in the mountains around the Taklamakan region, these underground currents hidden in the desert are activated one by one and begin to exert their effects.

As the melted snow flows through the underground river, the water level begins to rise and flood up from the bottom of the reservoir.

The water is used for two purposes, one is to power these machines, and the other is to transport granite stones. ”

Hearing him say this, the experts were stunned.

There is nothing surprising about this content now.

After all, at the end of the Eastern Han Dynasty, Ma Jun had already improved the keel waterwheel to improve irrigation efficiency.

The waterwheel is the originator of modern hydroelectric power.

"Yes, yes! How could I not have thought of it! Once there is a continuous flow of water through the waterwheel, it can supply energy to the first stage of mechanical equipment, and through the principle of gears, it is completely possible to drive larger-scale mechanical devices! ”

Academician Zhou slapped his face and exclaimed.

"I just stepped on it, the bottom of this so-called reservoir can be moved, by controlling the water level in this area, using the water flow to transport the yellow granite stone to a certain place according to the flow direction of the dark river."

Lin Yi's idea is definitely a brain-opener.

But no one on the scene questioned his speculation.

Because the huge mechanism that was still running said it all.

"Advisor Lin, there's a pull ring here!"

Just when everyone was discussing the content just now, Bai Lu kept groping along this reservoir, and sure enough, he gained something.

"Brother, there's one here too!"

Abdul also found a pull tab in the inner corner of the cistern.

"This is also available!"

"And this!"

Wang Qiang and Lan Yun's team members also made discoveries.

Inside each of the four corners of the cistern, there is a metal pull ring.

"This should be the switch, the others step back, I'll count to three, and everyone pulls this pull tab together!"

Lin Yi gave the order, and the others immediately retreated.

"There's no more mechanism here, right?"

Xiao Song muttered in a low voice.

Lin Yi waved his hand.

"No, this is already the core of the entire mechanism, which is where the 'tomb core' I have been looking for is located, and there will be no more mechanisms."

"It's like someone else has a gun in your chest, and you say it's too late to wear body armor at this time?"

Wang Qiang complained while holding on to the pull ring.

"One, two, three! Pull! ”

As the four of them vigorously pulled the pull ring from four directions, a creaking sound similar to the opening of a large iron door came into everyone's ears.

An X-shaped opening began to appear at the bottom of the cistern, and the yellow mud at the bottom began to flow down the outlet.

When the ring was stretched to the limit, I heard four "clicks" in unison, and the ring was stuck.

The bottom of the cistern was fully open, and everyone jumped up to the edge to look down.

A lake hidden underneath the ground appears in front of everyone's eyes.

The visual area is the size of several football fields.

When the sound of the yellow mud falling slowly disappeared, the sound of gurgling water and the "crunch" of the waterwheel came into everyone's ears.

In the middle of this underground lake, there are several flatbed boats.

This further confirms Lin Yi's view.

"The granite here is of high quality, but not much is used in this 'basalt cave'.

Rather, it was mined, using the undercurrents in the ground and transporting them elsewhere by these transport ships.

This means that the use of high-quality granite is a higher priority in that place.

If I'm not mistaken, the end of this underground river is the location of the 'Yellow Dragon Cave' guarded by the 'Four Elephant Arrays', that is, the 'Dragon Slaying Platform' after the reversal of Tiangang.

The one guarding there should be the King of Perfection himself! ”
