"Is the camera on your drone night vision?" Bai Yujing was very curious about this kind of electrical appliance, but Lin Ruoqiao was familiar with this thing, so he connected and installed it in three or two clicks, and put the drone down.

"It's not!"

"How can you see the darkness in there?"

Lin Ruoqiao looked at Bai Yujing with disdain while manipulating the drone to sink into the bottom of the well: "There is a searchlight on the drone. ”

Bai Yujing was speechless, deeply doubting his IQ, as the drone slowly deepened, Bai Yujing could see the scene at the bottom, this shaft was dug very deep, the walls of the shaft were made of bluestone bricks, strong and solid, at the bottom of the well, close to the bottom of the well, a circular hole appeared.

"This is the entrance, go in and take a look, see what's inside?" Bai Yujing also saw the scene displayed on the screen in Lin Ruoqiao's hand, and the lights on the drone shone in all directions, going deep into the hole.

Lin Ruoqiao controlled the drone to enter from the entrance of the cave, and the stunned passage went straight to the outside of the village, and finally led directly to an underground cave, Bai Yujing and Lin Ruoqiao watched it, controlled the drone to rotate left and right, and checked it with a searchlight, this is indeed an ordinary cave.

"What's the matter? Nothing?" Li Hao looked at Bai Yujing, Bai Yujing also frowned, this is not the same as imagined, what are they building this passage for?

Bai Yujing picked up the rope: "I'll go down and take a look, you pay attention, if something pulls me up immediately." ”

Bai Yujing came over this time with a special rope and climbing tools, using the method of double rope descent, fixing the rope on the dead banyan tree on the side, there is a protector on the rope, it is still relatively safe, after making sure that there is nothing wrong, and then go directly down to the wellhead.

Li Hao looked at Bai Yujing: "Be careful, if there is anything, shout immediately!"

Lin Ruoqiao was heartbroken: "I've seen nothing just now, what are you afraid of." ”

After Bai Yujing went down, he slowly lowered the rope, grabbed it with one hand and put it with the other, the dark place at the bottom of the well, the more he went down, the darker it became, there was a feeling of seclusion in the secret room, and he always felt like something was going to run out below.

It didn't take long for Bai Yujing to reach the bottom of the well, Bai Yujing stepped on the wall of the well, stuck himself, took a flashlight to shine below, looked at it, and found that there was still water under the well, but it was not deep, it seemed to be only about half a meter, and the water under the ground slowly seeped out, but when it reached the edge of the channel, it flowed out, Bai Yujing took a clear look inside, and stepped directly into the water after making sure that there was nothing below.

Only then did Bai Yujing see the passage, the passage was not big, only less than a meter long, Bai Yujing entered, it is estimated that he could only lie on his stomach, what is such a small entrance for? Bai Yujing looked at the water under his feet again and found a problem.

Bai Yujing held it with his palm again and licked it, and found that all that was gushing out of the ground now were freshwater resources, which could be drunk directly, which was different from the seawater well that Bai Yujing imagined before.

"So where did the sea water come from before?" Bai Yujing immediately discovered this problem, and took a flashlight to shine around, but there were no traces or clues around, it was a normal bluestone brick, the bottom of the cave was cold and cold, full of water vapor, and Bai Yujing didn't feel very comfortable.

"Hey, can you hear me?" Bai Yujing immediately shouted into the microphone around his neck.

"Oh, I can hear it, Lao Bai, what's going on over there?" was Li Hao's voice.

Bai Yujing immediately said: "Everything is normal, I have seen it, this cave entrance is only one meter and two high, it is too small, it is not quite like the entrance and exit of the entrance, and I found a little bit, the water gushing out of the bottom of this well is fresh water, not the seawater we found before." ”

Li Hao was also stunned for a moment: "How is it possible, we have all tasted it before, it is bitter and salty?"

Lin Ruoqiao immediately snatched the walkie-talkie in Li Hao's hand: "Will there be other entrances, and the water will flow in from somewhere else?"

Bai Yujing immediately said: "I also think that's the case, you guys slowly pull me up, I've seen the bottom of the well, there's nothing abnormal, I take a look when I go up, I may find something." ”

"Okay, we'll pull you up right away!" Lin Ruoqiao put down the walkie-talkie and immediately pulled Bai Yujing up, while Bai Yujing went up and looked back and forth with the flashlight in his hand shining on the walls of the wells on all sides, "You guys slow down, if it's too fast, you may miss something." ”

"I'll go, you don't think it's going to be difficult!" Li Hao immediately said, causing Lin Ruoqiao's contempt: "You wilted man, if you can't do it, just go aside." ”

The speed slowed down, and Bai Yujing also had time to observe, and when he ascended a little lower in the middle of the well, Bai Yujing immediately found a white stone slab, and this stone slab was a whole piece, like a portal, which stuck here tightly.

"Stop, stop, don't pull up. Hearing Bai Yujing's voice, the rope immediately stopped, Bai Yujing set himself up in the well, stepped on the stone wall, and used a flashlight to shine tightly on this stone slab, the stone slab is about two meters high, one and a half meters wide, just like a stone gate.

Bai Yujing knocked on it, and immediately heard a hollow sound coming from the stone slab, and the back was empty, Bai Yujing was overjoyed: "I have found it!"

"Really, Lao Bai, what did you find?" Lin Ruoqiao and Li Hao shouted together.

Bai Yujing immediately said: "A stone gate, this should be the entrance, we thought wrong before, this is the entrance, the one below is the waterway, used to release the water, this well is indeed a freshwater well, usually after the two entrances and exits are closed, what comes out is fresh water, before the entrance below was sealed, and the entrance above was opened, so what we see is seawater." ”

"Pull me up, and I'll try the mechanism to see if I'm the same as I thought. ”

Bai Yujing was pulled to the mouth of the well, and immediately saw the sunlight shining in from above, as well as the faces of Li Hao and Lin Ruoqiao, the darkness under the ground and the light above, as if divided into two worlds.

Bai Yujing directly pressed the mechanism carried by the copper ring into the inside, I have to say, Bai Yujing used the strength to eat, only to press it back into the distance, after a while, I saw the roar of the ground continued to sound, and finally clanged, the sound of the water came from under the well, and instantly saw the water splashing, filling the entire well and restoring it to the original water level.

Li Hao took a look: "What's the use of this, isn't it still in the water, do we want to swim in?"

Bai Yujing climbed up directly, sat on the edge of the well, looked at the water level that was rapidly rising below, and didn't quite understand the principle of this design, too, while sealing it, while opening it, isn't it full of water, what is it for?

"Maybe that's how they got in, swam in. Lin Ruoqiao was thoughtful.

Bai Yujing and Li Hao were stunned: "No, is there only a distance of water inside?" ”

Li Hao shivered in an instant: "Forget it, I rarely touch the water except for swimming in the pool at home." ”

Lin Ruoqiao shook his head: "I mean, will they also be able to survive in the water for a long time with the help of some tools?"

Bai Yujing immediately said: "It's really possible, I also thought about some things about this village yesterday, and I have some ideas for solving your problem Li Hao." ”

"What's the problem?"

"What's the way?" Li Hao and Lin Ruoqiao asked together.

Bai Yujing said: " I asked the professional I was looking for, and she said that it was because there were some hidden instability factors in your genes, and the people of this village, I suspect, must have used the blood of mermaids, you think about it, the previous name of the village said that Shuiyuan Village has never been in contact with the outside world, and no one from another village has ever married, or married someone from outside, and the history of the village can be traced back to hundreds of years ago, such a strange situation, there is only one possibility, this is a village of immortal people, in order to prevent others from discovering their abnormality, they refuse to contact the outside world。 ”

Li Hao nodded: "You told me about this yesterday, so what is the solution you have in mind?"

"Mermaid blood, in this case, there must be this thing in this village, this elixir, isn't it very simple to solve the problems on your body?" Bai Yujing said immediately.

Li Hao was thrilled after hearing this, but his mood became very complicated, and Bai Yujing also understood his mood: "Anyway, let's find it first, it's not hundreds of years ago, science and technology are developed, let's study it after we get it, maybe we can find a breakthrough, and even push human life science one step further, anyway, you still need a year, at least half a year, you can take it slowly." ”

Li Hao nodded: "Okay, I'll trouble you this time, Lao Bai, after the matter is completed, I will definitely not forget you!"

"Cut, I don't want you to be a big man to remember me, and I feel furry when I think about it!" Bai Yujing immediately said with a disgusted face.

Li Hao rose up angrily and wanted to kick Bai Yujing back to the bottom of the well, but Bai Yujing immediately thought of something, "Wait, you wait a minute!"

"What's wrong again?"

Bai Yujing looked at the ring handle and grabbed it again, this time Bai Yujing did not pull it all out, but stopped halfway through, and when it happened to be here, it would also be stuck.

"Sure enough, this is a three-stage mechanism, pulling out is to open the drain, pushing in is to open the entrance, and in the middle is to open both doors. Bai Yujing said happily, once again showing his ingenuity and calmly crushing the two people around him.

The movement beneath the ground was even louder, and the two gate valves opened, and the sound of water was churning like a big wave.
