"How do we save it? How do we save it?" Everyone was curious.
Hong Dali pointed at the scratches on the ground and said, "Everyone, look here. This should be where Big Turtle rested. That should be it. But now, it's lying here. What does this mean? It means that there should have been water here, but for some reason, the water suddenly disappeared. It was originally swimming in this underground lake and accidentally flipped over … "
"Yup, that must be it!" Everyone agreed.
"And then?" Tang Muxin asked.
"And then, we have to ask Chuyin." Hong Dali smiled and took the diving equipment from his lackey. "There must be an underground lake here. I remember seeing it before! So, what we need to do now is to check out the situation in the underground lake first, then come back and make a detailed plan! "
This could be said to be the most feasible method at the moment. Everyone looked at each other and nodded. "Let's do that!"
Retracing their steps, Hong Dali and the rest returned to the alligator snapping turtle's side. Hong Dali beamed with delight and patted the alligator snapping turtle's head. "Big turtle, hehe, we will save you later. Don't be anxious!"
"Ang —" The alligator snapping turtle expressed.
"Okay! Understood! " Hong Dali snapped his fingers. "Then, let's start now. Me, Brother Turn Back, and Chuyin, the three of us will go down to take a look. The rest of you stay here and keep in touch."
"Dali, don't take the risk!" Tang Muxin anxiously said.
"Don't worry! I'm very good at swimming! "Hong Dali smiled and replied.
As there were only three sets of diving equipment, only three people could go down. Hong Dali, Lin Chuyin, and Mu Huishou each found a corner to change their diving equipment. Very quickly, they finished changing. Lin Chuyin passed a communication device to Tang Muxin and insipidly said, "Communication device. You can talk anytime."
"O … OK!" Tang Muxin fiercely nodded.
"Wahahaha! Then, let's go down now! "Underwater adventure, here I come!
Speaking of which, the diving equipment made by Lin Chuyin was indeed quite powerful.
The oxygen system on her back was sufficient for a person to breathe underwater for 30 minutes. At the same time, because of the sci-fi style helmet, it made it possible for the three of them to communicate underwater. As the strongest technological geek, Lin Chuyin chose a physical communication device underwater. This could effectively avoid signal interference.
Therefore, after the three of them entered the water, it was basically no different from when they were on land. The only difference was that the water pressure was slightly higher, making it slightly difficult for them to breathe.
The three of them dived all the way down and soon came into contact with the bottom of the pool. The water wasn't too deep, but standing in the water, one could feel that the water wasn't stagnant, but alive. Occasionally, there were some small fishes and shrimps in the water. When they saw the light, they all swam over curiously.
"Everyone, be careful." Mu Huishou said softly, "This place seems to be connected to an underground lake. Be careful of any unknown creatures in the water."
As the saying goes, when an animal lives for a long time, it's easier for it to get close to a monster. Some time ago, he saw with his own eyes the tuna that weighed more than 800 kilograms that was fished out of the sea. It should be known that this thing usually weighed only a few kilograms. It was not an exaggeration to say that it was a monster that weighed more than 800 kilograms.
No one had discovered this underground lake for many years. It was hard to say what was in the water.
"Yup, yup." Hong Dali agreed. Then, he used the underwater lighting device in his hands to illuminate the surroundings. "This place seems to be very deep. Chuyin, can you calculate how deep it is? Oh right, how long can we dive for? "
Lin Chuyin's voice sounded very quickly. "According to the consumption of the compressed air bottle, the volume of the compressed air bottle I prepared is 15 liters. Diving time = [volume of the air bottle (liters) * (inflated pressure – indicated pressure of the signal valve)]/[air consumption per minute under normal pressure * (1 + 0.1 * diving depth) * 0.098]."
Hong Dali frantically said, "That, Chuyin, just tell me the result directly. I don't understand at all!"
"Oh." Lin Chuyin very quickly calculated. "0.098 is the density of fresh water. Usually, the approximate value of 1 is used, so it can be ignored. 1 refers to one atmosphere of pressure on land. Currently, diving for two minutes consumes close to one-fifteenth of the compressed air. According to the calculation formula, we can still dive for 27 minutes. The current depth is about 16 meters or so. "
Hong Dali nodded and said, "Yup, about 16 meters or so. Twenty-seven minutes. That means that we can only go forward for 15 minutes at most before we have to turn back, right?"
"Yup, yes." Lin Chuyin said, "According to the map I deduced, we need to continue walking forward for another 20 meters and we will be able to see the entrance to the underground lake."
"That's good, that's good." Hong Dali suddenly laughed loudly. "Wow, what a big fish!"
Currently, in front of Hong Dali was a huge carp that was more than one meter long. Mu Huishou smiled and said, "I said that there would definitely be a big guy inside. Such a big carp, it should be about 50 to 60 kilograms, right? "
"Definitely!" Hong Dali shone the light to the side again. "Quick, look, there's one there too! They're all very big! They must have lived for many years, right? "
As he was making a big fuss, Lin Chuyin suddenly said, "The direction of the water flow is correct. Currently, it has already bypassed the bottom of the cave and is heading upwards. The water pressure is slightly weaker than before. There should be some new discoveries in front."
One must know that although the water looked normal, the deeper they went, the more shocking the water pressure was. The shallower the water pressure was, the weaker the water pressure was.
Lin Chuyin's body's senses were as accurate as a machine's. If she said that, then it would definitely be correct.
The three of them instantly increased their speed and walked forward. Suddenly, the water pressure in front of them decreased drastically. Hong Dali was overjoyed and wanted to continue floating upwards. Suddenly, with a "bang" sound, his head actually knocked into a big rock.
"Aiya, this damn big rock is going to knock me to death!" Hong Dali yelled loudly.
"This is …" Mu Huishou stretched out his hand and slowly touched the rock. Not long after, he suddenly touched a small hole. The water in this underground lake hadn't dried up after so many years. It turned out that the water was actually seeping in bit by bit from this small hole.
"It's this big rock that's blocking the water source!" Mu Huishou hurriedly yelled, "As long as we move this big rock away, that big turtle will probably be released!"
"Really?!" Hong Dali exclaimed in surprise. "Blow up this big rock?"
"Oh, not yet." Lin Chuyin thought for a while and said, "If the rock is blown up, the water current will be very strong. We have to go out first, or else we will be washed to death by the water current."
Once the stone was blown up, the underground lake on the other side would be pressured, and there would definitely be a strong flow of water. If there were more stones, they would definitely be crushed to death — the most important thing was that there were no explosives …
"Let's go back first. I'll ask someone to send compressed air bottles and underwater explosives over!" Now that there was a solution, naturally, there was no need to hesitate. Mu Huishou laughed and said, "As expected, it's still good to hang out with Young Master Hong Dali."
How could it not be good? Previously, when he returned from the Hong Family estate, he bought two scratch-off tickets and won more than 200 yuan …
Returning from underwater, once they reached the shore, Hong Dali ran to the alligator snapping turtle and excitedly said, "Hahaha, big turtle, we can save you! Hahaha! "
"Ang —" The alligator snapping turtle seemed to understand Hong Dali's words and let out a happy cry.
Instantly, Mu Huishou started contacting the engineers outside. Very quickly, the compressed air bottles and underwater remote-controlled explosives were sent over. It was a very intricate device connected to a remote-controlled wire of about 200 meters. As long as the device was placed under the big rock and stuck properly, then with a press of the button, the big rock blocking the water source would be blown into pieces with a bang.
"I'll go!" Mu Huishou took the underwater explosives and said, "I can go by myself. When I come back, I can blow it up."
"OK! I'll help you look after it, haha. "
Mu Huishou instantly dove into the water again. This time, he was very familiar with it and returned within 20 minutes. Once he reached the shore, he smiled and said, "OK, the installation has been completed. Let's quickly find a place to stay. Otherwise, if it blows up later, we might all drown inside."
"Then, everyone should go out first." Hong Dali suggested. "After blowing up the big rock, we'll come in again based on the situation. Don't let all of us drown inside."
As he spoke, Hong Dali patted the turtle's shell and beamed with delight. "Big turtle, when the water floods in later, you'll have to rely on yourself to turn the situation around!"
"Ang —" Big turtle let out another long roar and agreed.
Hearing that, Hong Dali instantly brought his people and ran out. As he ran, he excitedly said, "Then, let's get ready now. Hahahaha! Big turtle, watch Big Bro Dali save you! "
After Hong Dali and the others retreated along the path they came from, Hong Dali took a deep breath and then fiercely pressed the button of the remote bomb in his hand!
"Boom —"
A dull explosion sound came from inside the mountain. Then, in the image taken by the flying device that was left in the cave, the small lake in the cave seemed to be boiling. Bubbles started to appear in the middle of the lake.
"Big turtle, get ready. The water is coming soon!" Hong Dali looked at the screen of the laptop and worriedly said.
"Hualala —" The water from the underground lake on the other side poured in. Under the huge water pressure, the impact was huge. With a loud bang, a water pillar shot up from the center of the lake and directly hit the shell of the alligator snapping turtle. One inch, two inches, one foot, two feet, ten feet, twenty feet!
On this side, the water hit the shell of the giant turtle, and on the other side, the lake water poured into the entire cave. In the blink of an eye, the lake water had already grown to a depth of more than one meter!
"Wow!" The power of nature was right in front of them. Hong Dali and the others stared in bewilderment and exclaimed in surprise!
"Boom —" The buoyancy in the water was activated, and the giant water pillar rushed forward. The alligator snapping turtle's body, which weighed who knew how many thousands of pounds, actually slowly stood up. Then, with a "boom" sound, the earth shook and the mountains shook. The giant turtle's huge body really turned over!
