The drill bit on Mo Lian's arm began to deform again, returning to its original appearance as a mechanical hand.
"I can feel that this stone ball is hollow, but it is too big and I can't drill through it." Mo Lian sighed.
"Hollow?"
Jiang Zhonglou was stunned. He thought the stone ball was solid: "What on earth is going on? When I went to Longkou Cave Jishuitan to kill the giant python that night, I didn't find any passage in the pool!"
"If I guessed correctly, there should be two large stone balls like this at both ends of the passage in Longkou Cave, just like the ball valves in the faucet..."
Mo Lian sighed: "Normally, this huge ball valve is closed, but if there is a huge force impacting these two ball valves, it will rotate and then open...
And when the huge power disappears, the two stone balls will automatically rotate again and continue to close the channel!"
"Um...you're saying that the underground river from Longkou Cave to here is like a huge sewer pipe, and there are ball valves made of large stone balls at each end of the pipe?"
Although Jiang Zhonglou doesn't know much about modern society, he has seen the structure of a ball valve on the Internet.
The ball valve is a round ball with a cylindrical hole in the middle. When the hole is turned to the position connected to the pipe, the valve opens, otherwise, the valve closes...
"Not bad!" Mo Lian nodded.
"But... what kind of huge force can push such a large stone ball to rotate?"
Jiang Zhonglou raised his head and looked at the huge stone ball with a diameter of nearly ten meters.
"It's probably the Ningjiang tide!"
Mo Lian sighed: "Today's high tide is unprecedented in a hundred years. The tide hit the Longshou Cliff, instantly generating huge pressure and breaking open the two stone ball valves in Longkou Cave...
The tide rushed in here under the influence of water pressure, bringing us in too!"
"Hmm...yes, that's probably the case!" Jiang Zhonglou nodded.
"There is another possibility..." Mo Lian thought.
"What's possible?"
"Of course something triggered the mechanism of these two huge stone balls, actively causing them to open the valve before the tide arrived!"
"Actively triggering it? You mean...someone knew about this mechanism and took the initiative to open it, deliberately causing us to be rushed into here?"
Jiang Zhonglou was startled and immediately thought of the omnipotent Tian Nanxing...
"It doesn't have to be a person...or something else..." Mo Lian thought.
"What? Something else? What could it be?" Jiang Zhonglou was stunned, "You can't say... what kind of ghost is it?"
Mo Lian has incredible high technology, so he shouldn't believe in ghosts and gods, right?
"Of course not ghosts, but... animals!"
Mo Lian raised her head and looked at Jiang Zhonglou: "Have you forgotten the barbarian birds we saw last night? Doesn't it say in "The Classic of Mountains and Seas" that when you see them, you will get flooded?"
"this..."
Jiang Zhonglou was stunned: "This is just...a legend fabricated by the ancients, right? There is no scientific reason at all!"
"Although the ancients did not understand scientific principles, the information they recorded was not necessarily nonsense based on imagination. There must be some truth to it..."
Mo Lian sighed: "I guess it should be that whenever someone saw a barbarian bird, the Ningjiang River would have a big tide. Over time, there was a saying that seeing a barbarian bird would cause a flood. So, he wrote "The Classic of Mountains and Seas"
》The person recorded this information.”
"this..."
Jiang Zhonglou found that Mo Lian's analysis was very reasonable, so he also thought about it: "You mean, maybe the barbarian bird accidentally opened the mechanism of these two huge stone ball valves, and then triggered a huge tide in the Ningjiang River?
But... the Manman Bird is just a kind of bird, how can it have the ability to cause a huge tide that has never happened in a century?"
"Of course it is impossible for the barbarian bird to cause a huge tide..." Mo Lian said, "I guess it must have sensed that a big tide was about to happen, and then it appeared at Longshou Cliff. As a result, it somehow triggered the dragon's mouth.
The trap in the cave!"
"Well...that makes sense!"
Jiang Zhonglou nodded: "Many animals have the ability to predict earthquakes, tsunamis, and storms. Since this barbarian bird is an ancient divine bird, it is not surprising at all that it can predict the tide of Ningjiang River in advance...
Moreover, I vaguely saw the pair of wild birds flying into Longkou Cave last night..."
Before Jiang Zhonglou finished speaking, he heard a rustling sound coming from above the mouth of the one-horned dragon, as if there was something...
Mo Lian reacted very quickly, picked up Jiang Zhonglou, and flew out of the dragon's mouth to the top!
I saw two strange birds emerging from the nostrils of the one-horned dragon statue, as if they were the two I saw last night!
This time, being so close, Jiang Zhonglou saw through the bright silver spirit light that these two birds indeed had only one eye and one wing!
Sure enough, it is the mysterious Manman Biwingbird!
As soon as the two wild birds saw Mo Lian carrying Jiang Zhonglou and flying up, they immediately jumped up and flew into the air!
Although they were standing in front of the two nostrils of the one-horned dragon statue, they flew together in tacit agreement with this leap!
Their necks quickly intertwined, and the two birds merged into one bird!
"Plop tap tap!"
They flapped their wings and flew into the distance at lightning speed!
Mo Lian twisted her waist, hugged Jiang Zhonglou and ran after him!
The red and white flames under her feet made a fierce "chichi" sound, as if they had reached full speed!
However, the pair of wild birds were like lightning, faster than Mo Lian!
The key is that they keep flying down, like a rapidly falling stone!
Even faster than free fall!
Mo Lian hugged Jiang Zhonglou and fell rapidly. She kept chasing downwards, but she still couldn't catch up with the pair of wild birds!
Not long after falling, we reached the bottom of the cave.
I saw that there was actually a huge, circular lake below!
The circular lake is surrounded by upright mountain walls, with countless waterfalls flowing down into the circular lake...
In the center is the towering stone pillar. Around the stone pillar, there are also eight waterfalls flowing down into the ring lake.
These eight waterfalls flow out from the eight gaps of the nine-petal lotus on the top of the stone pillar.
Jiang Zhonglou was surprised to find that there were countless huge waterwheels built around the circular lake!
These waterwheels are impacted by the water flow of the waterfall and are constantly turning, some fast, some slowly...
There are also eight huge waterwheels beside the central stone pillar. However, the top one-horned dragon no longer sprays water, and the water in the Nine-petal Lotus Lake is no longer overflowing. Therefore, the eight waterfalls beside the stone pillar flow.
Very thin...
Those eight huge waterwheels also rotated extremely slowly.
Jiang Zhonglou looked at the waterwheel in Mo Lian's arms, but Mo Lian was still chasing the pair of wild birds!
When we reached the lake, the pair of wild birds actually plunged into the lake!
Mo Lian quickly stopped and floated on the lake.
The flames on the soles of her feet sprayed onto the water, creating a large cloud of white mist!
After a long time, the pair of wild birds did not come out of the lake...
On the lake, only a circle of ripples plunged into the water...
"I didn't expect that this wild bird can actually dive."
Jiang Zhonglou was depressed.
"Have you forgotten? Did they swim up from the Ningjiang River yesterday?" Mo Lian also sighed depressedly.
"What are these waterwheels for?"
Jiang Zhonglou looked at the huge waterwheels surrounding the circular lake.
"Of course it's the power device." Mo Lian sighed.
