"How's it?" Everyone is very curious.
Hong Dali pointed to the scratches on the floor and said, “See this, this should be the place where ordinary turtles rest, there is no doubt about that. But now, he was lying there. What does that mean for us? This tells us that there should be water down there, but it's gone for a reason. Supposed to be swimming at the bottom and accidentally capsized … "
"Yup, that must be the problem!" Everyone agrees.
"Then, what are we doing now?" Tang Muxin asked.
"Then, we should ask Chuyin now. “Hong Dali smiled and picked up the diving equipment from his henchmen. “It must be connected with the underground lake. I remember seeing it last time! So, all we need to do now is check the situation on the lake. Then, we will make a detailed plan after that! ”
This is the most viable option at the moment. Everyone looked at each other and nodded in unison. "Okay, let's do that!"
Then, they returned to the crocodile flicking the turtle. Hong Dali happily patted the head of the snapping crocodile. “Big turtles, hehe, it looks like we will be able to save you in just a short time. Don'tbe nervous! "
"ROBBING!!" The crocodile snapped the turtle replied.
"GOOD! Be understood! ” Hong Dali flicked his finger. "Then, we'll start now. Brother Back, Chuyin and I, the three of us will come down and take a look. You all stay here and are ready to communicate with us. ”
"Dali, don't risk it yourself!" Tang Muxin said anxiously.
"Don't worry! My swimming skills are great! " Hong Dali laughed and said.
Since there were only three sets of diving equipment, therefore, only three people could go down at once. Hong Dali, Lin Chuyin, and Mu Huishou instantly found their respective corners to turn into diving gear. Very quickly, everything is done. Lin Chuyin handed over the communication device to Tang Muxin and said, “This is a communication device. We can communicate through this at any time. ”
"O ... OK!" Tang Muxin nodded loudly.
“Brouhaha! Comeondown! ” Undersea expeditions, I'm coming!
Speaking of which, the diving equipment that Lin Chuyin made was indeed incredible.
The oxygen system in their back is enough for a person to breathe for half an hour in the water. At the same time, because helmets are like sci-fi, even though they are underwater, they can still communicate with each other — as a super tech geek, even though they are underwater, Lin Chuyin chose a physical wired communication device for underwater use. In this way, they can prevent possible signal interference.
Therefore, when the three of them descended into the water, it was basically no different from being on the ground. The only difference is that the water pressure is slightly high, causing little difficulty in breathing.
The three of them plunged down and immediately touched the bottom of the sea. The depth of the water was not very deep, but once they were in the water, they could feel that this was not stagnant water but flowing water. There are small fish and shrimp that occasionally swim past. Upon seeing their lighting equipment, they all strangely swam close to the three of them.
“Everything, be careful. "Mu Huishou softly said," This place seemed to be connected to an underground lake, be careful of any unknown creatures that might be there. ”
For animals, the longer they live, the more they become like monsters. Recently, Mu Huishou saw with his own eyes that 800 KG of tuna were pulled out of the sea. Compared to normal ones that only weighed a few KG, it was no exaggeration to call 800 KG a monster.
This underground lake has not been discovered by people for many years, it is uncertain what might be underwater.
“Yup, yup. ”Hong Dali replied, then used his underwater torch to illuminate his surroundings. “It seems very deep here. Chuyin, can you calculate the depth? Oh right, how long can we dive? ”
Lin Chuyin's words were sent out very quickly. "If we calculate using the usage rate in a compressed air bottle, the volume I prepared in it has 15 liters, \= dive time [air bottle volume (in liters) * (pressure increased pressure signal indicator)] / [normal pressure usage per minute * (1 + 0. 1 * water depth) * 0. 098]. ”
Hong Dali frantically said, “Eh, Chuyin, just let us know the result. I don't understand what you just said! "
"Oh. '' Lin Chuyin very quickly calculated the result. "0. 098 is the density of water in fresh water. Normal value is close to 1, so it is negligible.1 refers to the air pressure above the ground. Currently, we have been diving for two minutes and using 1/15 of the compressed air. According to the formula, we can still dive for 27 minutes. The current water depth is about 16 meters. ”
Hong Dali nodded and said, “Yup, the depth is about 16 meters, 27 minutes. That means, we can go forward for at most 15 minutes before we need to go back, right? ”
"Yes that's right . "Lin Chuyin said," According to the map I had expected, we should be able to see the entrance to the underground lake after moving forward another 20 meters. ”
“It was good, it was good. “Hong Dali suddenly laughed out loud. "Wow, what a big fish!"
Right now, in front of Hong Dali, there was a huge one meter long goldfish. Mu Huishou smiled and said, "I said that there will be many people here. Big goldfish, it weighs 25-30 KG, right? ”
"That's for sure!" Hong Dali shone the flashlight to the side again. "Look, there's one there too! It's also huge! This one must have lived for years, right? ”
As he exclaimed, Lin Chuyin suddenly said, "The direction of the water flow is accurate. Right now, we have gone to the bottom of the cave. We're going up now, the water pressure is a little bit lower than it is now. We need to find something new ahead. ”
The accuracy of Lin Chuyin's body sensor was similar to that of a machine. If he said so, that must be the case.
The three of them immediately accelerated and advanced. Suddenly, the water pressure dropped very upward. Hong Dali was happy and wanted to float. Suddenly, a thud rang out as his head completely crashed into a boulder.
"Geez, this fucking rock is killing me!" Hong Dali continued to shout loudly.
"This is ..." However, Mu Huishou reached out and moved his hand about the outline of the stone. Suddenly, he felt a small hole. This underground lake does not dry up after many years as water seeps through this small hole.
"This is a rock that blocks the water source!" Mu Huishou hurriedly shouted. "As long as we can move this stone, that big turtle will be able to be saved!"
"Thank you!?" Hong Dali was shocked. "Blow up this big rock?"
“Oh, we can't do that yet. "Lin Chuyin thought for a moment and said," Blowing up a rock would cause water to flow at an incredible speed. We have to get out first, otherwise we will be killed by the impact of the water flow. ”
After this stone exploded, due to the pressure, the water on the other side of the lake would flow down very strongly. If it was carrying stones or something like that, it would definitely kill them — the most important thing is, they have no explosives with them …
“Come back first. I'll tell someone to bring us bottles of compressed air and underwater explosives! " As there is a solution now, there is certainly no need to hesitate. Mu Huishou laughed and said, "Indeed, our luck would be good if we were near Young Master Dali. ”
How could that not be good? Previously, when he left the Hong Family estate, he bought two scratchc cards and won 200 plus yuan …
They came back like they were back to the crocodile turtle. Once they were on land, Hong Dali ran to the alligator who took the turtle and happily said, “Haha, big turtle, we will be able to save you! Ha ha ha!"
"Reproof!!" The crocodile snapped the turtle seemed to understand his words and shouted delightfully.
Mu Huishou directly communicated with the engineers outside. Very quickly, bottles of compressed air and explosives controlled from under the sea were delivered. It was a very delicate device, connected to a 200 meter long remote control cable. Once they locked this device somewhere into the rock and pressed a button, they would be able to blow the huge rock into pieces.
"I'm going!" Mu Huishou picked up the underwater explosives and said, "I can go by myself, you all wait here. We'll blow up the rock as soon as I get back. ”
"GOOD! I'll take care of you, haha. ”
Mu Huishou immediately plunged into the water again. This time, as he was already used to his path now, he came back in just 20 minutes or so. As soon as he appeared, he smiled and said, “OK, I have already successfully installed the device. Let's hurry up and find a place to hide. Otherwise, we will drown here when the rock is blown up. ”
"Then, everybody, let's go first. "Hong Dali suggested. "After we block the stone, we can go back again. Don't drown in here. ”
When he said so, he patted the shell of the big turtle, laughed happily and said, “The big turtle, once the water flows, you have to rely on yourself to flip!”
"Rubber!" The Big Turtle gave another long roar in return.
Hearing his reply, Hong Dali immediately brought everyone out and ran. As he ran, he happily said, "Then, let's prepare ourselves, hahaha! Big turtle, watch Brother Dali save you! ”
As soon as Hong Dali and the others retreated from the cave, Hong Dali took a deep breath and pressed the button!
EXPLOSIONS
A deep explosive sound came from within the mountain. Then, from the images sent back from the recording device left inside, the small lake in the cave seemed to have erupted. The air bubbles started bubbling out from the center of the lake.
"The big turtle, get ready, the water is coming now!" Hong Dali looked at the monitor on the laptop and said anxiously.
Swoosh—
As soon as the water on the other side of the lake started flowing down, under the immense pressure, from the middle of the lake, a column of water surged with explosions, directly shooting at the tortoise shell. One inch, two inches, one foot, two feet, 10 feet, 20 feet!
As the water column pushed against the turtle shell, the water depth in the cave was already one meter deep as the water flowed down!
"Woo!" The power of nature was displayed right before their eyes. Hong Dali and the others were astonished and exclaimed in surprise!
Explosion-out
Due to the buoyancy of the water and the impact of the water column, the crocodile flicked the body of the weighted turtle unsure of how many tons were actually slowly erected into a standing position. Then, with a loud explosive sound combined with the mountain shake, the giant body of the turtle completely turned around!
