"How?" Everyone was very curious.Hong Dali pointed at the scratches on the floor and said, "Look here, this should be the place where the turtle used to rest, there"s no doubt about that. But now, it"s lying down there. What does that tell us? This tells us that there should be water down there originally, but it disappeared for some reason. It should have been swimming at the bottom and accidentally flipped over…"
"Yup, that must be the case!" Everyone agreed.
"Then, what do we do now?" Tang Muxin asked.
"Then, we must ask Chuyin now." Hong Dali smiled and took the diving equipment from his lackey. "This must be connected to an underground lake. I remember I saw it last time! So, what we need to do now is to check the situation at the lake. Then, we shall come up with a detailed plan after that!"
This was the most viable option currently. Everyone looked at each other and nodded in unison. "OK, let"s do that!"
Then, they returned back to the alligator snapping turtle. Hong Dali delightfully patted the alligator snapping turtle"s head. "Big turtle, hehe, looks like we will be able to rescue you in just a short while. Don"t be nervous!"
"ROAR!!" The alligator snapping turtle answered.
"OK! Understood!" Hong Dali snapped his fingers. "Then, we shall start now. Brother Turn Back, Chuyin and me, the three of us shall go down and take a look. The rest of you stay here and be ready to communicate with us."
"Dali, don"t take the risk yourself!" Tang Muxin anxiously said.
"Don"t worry! My swimming skills are very good!" Hong Dali laughed and said.
Because there were only three sets of diving equipment, therefore, only three people could go down at one time. Hong Dali, Lin Chuyin, and Mu Huishou instantly found a corner each to change into the diving gear. Very quickly, all of them were done. Lin Chuyin handed a communication device to Tang Muxin and insipidly said, "This is a communication device. We can communicate through this anytime."
"O… OK!" Tang Muxin violently nodded.
"Brouhaha! Let"s go down then!"Underwater expedition, here I come!
Speaking of which, the diving equipment that Lin Chuyin made was indeed awesome.
The oxygen system on their back was enough for a person to breathe for half an hour in the water. At the same time, because of the sci-fi like helmet, even though they were underwater, they could still communicate with one another—being a super technological geek, Lin Chuyin chose physically wired communication devices for underwater use. This way, they could prevent the possibility of signal interference.
Therefore, when the three of them went down into the water, there was basically no difference from being on the ground. The only difference was that the water pressure was slightly high, causing a bit of difficulty in breathing.
The three of them dived all the way down and soon touched the seabed. The depth of the water wasn"t too deep, but once they were in the water, they could sense that this wasn"t stagnant water but flowing water. There were small fishes and prawns that occasionally swam past. Upon seeing their lighting equipment, they all curiously swam close to the three of them.
"Everyone, be careful." Mu Huishou softly said, "This place seems to be connected to the underground lake, be careful of the unknown creatures that may be down there."
For animals, the longer they live, the more monster-like they become. Just not long ago, Mu Huishou saw with his own eyes that 800 KG tuna being pulled out from the sea. Compared to normal ones that only weight a few KG, it wasn"t an overstatement to call the 800 KG one a monster.
This underground lake hadn"t been discovered by people for so many years, it was uncertain of what might be down there in the water.
"Yup, yup." Hong Dali replied, then used his underwater torchlight to light up his surroundings. "It seems to be really deep here. Chuyin, can you calculate the depth? Oh right, how long can we dive?"
Lin Chuyin"s words were transmitted over very quickly. "If we calculate using the level of usage in the compressed air bottle, the volume I prepared in it has 15 liters, the diving time=[volume of the air bottle(in liters)*(inflated pressure-signal indicator pressure)]/[normal pressure usage per minute*(1+0.1*depth of the water)*0.098]."
Hong Dali frantically said, "Er, Chuyin, just directly tell us the result. I didn"t understand a thing you just said!"
"Oh." Lin Chuyin very quickly calculated the result. "0.098 is the density of water in fresh water. The normal value is close to 1, so it"s ignored. 1 refers to the air pressure above the ground. Currently, we have dived for two minutes and used up 1/15 of the compressed air. According to the formula, we can still dive for 27 minutes. The current depth of the water is about 16 meters."
Hong Dali nodded and said, "Yup, depth about 16 meters, 27 minutes. That means to say, we can go forward for at most another 15 minutes before we need to turn back, right?"
"Yes, that"s right." Lin Chuyin said, "According to the map I guessed, we should be able to see the entrance to the underground lake after moving forward another 20 meters."
"That" good, that"s good." Hong Dali suddenly laughed loudly. "Wow, what a huge fis.h.!.+"
Currently, in front of Hong Dali, there was a one meter long huge carp. Mu Huishou smiled and said, "I said that there would be large fellows down here. Such a huge carp, it must weight 25-30 KG, right?"
"That"s for sure!" Hong Dali shone his torchlight at the side again. "Look, there"s one there too! It"s also very big! This one must have lived for many years, right?"
As he was exclaiming, Lin Chuyin suddenly said, "The direction of the water flow is accurate. Currently, we have gone around the bottom of the cave. We"re going upwards now, the water pressure is slightly lower than just now. We should be able to discover something new up ahead."
One should know that, although the water seemed very normal, as one went down, the water pressure would become more and more incredible. Also, the shallower the water was, the lower the water pressure was.
Lin Chuyin"s body sensor"s accuracy was akin to that of a machine. If she said so, that must be the case.
The three of them instantly sped up and went forward. Suddenly, the water pressure decreased tremendously upwards. Hong Dali was delighted and wanted to float up. Suddenly, athudsound could be heard as his head actually hit a large rock.
"Oh my, this d.a.m.n rock is killing me!" Hong Dali kept shouting loudly.
"This is…" However, Mu Huishou reached out and moved his hand about the outline of the rock. Suddenly, he felt a small hole. This underground lake didn"t dry up after so many years all because of the water seeping through this small hole.
"It"s this rock that"s blocking the source of the water!" Mu Huishou hurriedly shouted. "As long as we can move this rock away, that big turtle will be able to be rescued!"
"Really!?" Hong Dali was surprised. "Blow up this huge rock?"
"Oh, we can"t do that yet." Lin Chuyin thought for a while and said, "Blowing up the rock will cause the water to flow at a tremendous rate. We have to go out first, or else, we will be killed by the impact of the water flow."
Once this rock was blow up, because of the pressure, water on the other side of the lake would flow down very strongly. If it carried stones or such with it, that would definitely kill them—the most important thing was, they didn"t have explosives with them…
"Let"s go back first. I"ll tell someone to bring us compressed air bottles and underwater explosives!" Since there was a solution now, there naturally wasn"t any need to hesitate. Mu Huishou laughed and said, "Indeed, our luck will become good if we are around Young Master Dali."
How could it not be good? Previously, when he left the Hong Family estate, he bought two scratchcards and won 200 plus yuan…
They returned the way they came back to the alligator snapping turtle. Once they were on land, Hong Dali ran over to the alligator snapping turtle and delightfully said, "Haha, Big turtle, we will be able to rescue you! Hahaha!"
"Roar!!" The alligator snapping turtle seemed to understand his words and gave a delightful shout.
Mu Huishou instantly communicated with the engineer outside. Very quickly, the compressed air bottles and underwater remote-controlled explosives were sent in. It was a very delicate device, connected to a 200-meter long remote control wire. Once they locked this device somewhere into the rock and pressed the b.u.t.ton, they would be able to blow that huge rock to bits.
"I shall go!" Mu Huishou took the underwater explosives and said, "I can just go alone, the rest of you wait here. We shall blow up that rock once I come back."
"OK! I will look out for you, haha."
Mu Huishou instantly dived into the water again. This time, because he was familiar with the way now, he returned in just 20 minutes or so. Once he came up, he smiled and said, "OK, I have successfully installed the device. Let"s hurry up and find a place to hide. If not, we will be drowned here when the rock is blown up."
"Then, everyone, let"s go out first." Hong Dali suggested. "After we block up the rock, we can come back in again. Let"s not get drowned here."
As he said so, he patted the big turtle"s sh.e.l.l, laughed in delight and said, "Big turtle, once the water flows in, you will have to depend on yourself to flip over!"
"Roar!" The Big turtle gave a long roar again as a reply.
Hearing its reply, Hong Dali instantly brought everyone out and ran. As he ran, he delightfully said, "Then, let"s prepare ourselves, hahaha! Big turtle, watch as your Brother Dali saves you!"
Once Hong Dali and the rest retreated from the cave, Hong Dali sucked in a deep breath and pressed the b.u.t.ton!
BOOM—
The sound of a deep explosion came from inside the mountain. Then, from the images sent back from the recording device left inside, the small lake in the cave seemed to have erupted. Air bubbles started bubbling out from the center of the lake.
"Big turtle, get ready, the water is coming now!" Hong Dali looked at the monitor on the laptop and worriedly said.

Once the water on the other side of the lake started flowing down, under that enormous pressure, from the center of the lake a column of water shot up with a boom, directly shooting onto the turtle"s sh.e.l.l. One inch, two inches, one foot, two feet, 10 feet, 20 feet!
As the water column pushed on the turtle"s sh.e.l.l, the depth of the water in the cave was already a meter deep as the water rushed down!
"Woo!" The force of nature was displayed right before their eyes. Hong Dali and the rest were astonished and exclaimed in surprise!
Boom—
Due to the buoyancy of the water and the impact from the water column, the alligator snapping turtle"s body that weighted not sure how many tons actually slowly got erected into a standing position. Then, with a loud booming sound combined with the shaking of the mountain, the giant turtle"s enormous body really turned over!
