"What should we do? This is a closed underwater space, and it is also in the shape of a trumpet. If the mine explodes, the seabed on the top of the cave will definitely be blown away, and we may also be sprayed out of the sea along with the seawater. Although the 'Pippi Shrimp' is very strong, it is not designed to cope with such situations. I cannot guarantee that it can withstand it." Yang Xueting said with a trembling voice.
"It's nonsense. I definitely can't handle it. The pressure in the submarine is still 90 meters underwater. If the hull breaks even a little, we will be sprayed out from the crack like ketchup." Tian Yong's eyes were scarlet and he faced He was also anxious about the imminent death. The professor and Adeline were already dumbfounded, their faces were ashen, and they couldn't even speak.
"I remember there were four 'spear chain fixing ropes' on the boat. We dived quickly against the rock wall. Do you still remember the cave entrance at 250 meters? That was our only way to survive!" Ling Hao quickly made a decision Decide.
There was no time to hesitate at all. Facing danger together again and again allowed Ling Hao's team members to build trust in each other that they could trust with their lives. Regardless of whether Ling Hao's idea was feasible or not, Yang Xueting chose to implement it without thinking.
The rudder stock was pushed to the bottom, the motor power was increased to the maximum, and the inside of the boat began to be rapidly pressurized. "Hold on tight, pay attention to balancing the ear pressure!" Yang Xueting shouted, and the "Pippi Shrimp" immediately went up and down, the propeller stirred up a string of bubbles, all the backup jet water boosting devices were turned on, and it dived vertically downwards. And go.
100 meters, 140 meters, 170 meters... In less than 30 seconds, the "Pippi Shrimp" dived nearly 100 meters, and the pressurization speed of the internal space reached the limit of the human body. The professor and Adeline Symptoms of ear pain began to appear, and he started to rub his face in pain. Usually when diving encounters this situation, you must stop diving or even surface slowly to relieve the symptoms to avoid causing physical harm. But at this moment, everyone is running for their lives. Why are you worried about getting this?
Suddenly, the seawater surged, and a huge "bubble column" rose from below, suddenly tearing apart all the surrounding creatures in its path, and rolled up a large amount of black seaweed, like a mushroom cloud from the abyss of hell. The entire cave shook violently.
Sure enough, the severed mechanical arm landed on the mine without death. The "big killer" that had been floating for more than half a century proved with facts how terrifying it still was. The violent explosion caused the water pressure to rise suddenly. The heat wave not only caused the surrounding seawater to instantly vaporize, but the fragments of the mine also shot towards the surrounding rock walls. The luminous substances on the rock wall were indeed flammable, and were actually ignited by high-temperature fragments. The dark red flames immediately spread around, then spread to the entire rock wall, and then surged upward along the rock wall, like a yin fire on the seabed. Horrible and weird.
"Quick! Launch the 'Spear Chain Fixing Rope'!" Ling Hao shouted. At this moment, the "Pipi Shrimp" has dived to about 220 meters, and the entrance of the cave can be vaguely seen from a distance.
Yang Xueting slightly adjusted the posture of the submarine and slapped a button suddenly. Four half-meter-long steel spears flashed with cold light, each carrying a two-finger-thick rope chain and shot toward the entrance of the cave. Sparks flew everywhere, three of them were firmly inserted into the rock wall, while the other one did not shoot into the rock wall due to the angle problem, but was bounced away.
Almost at the same time, the bubble column swept over, and the "Pippi Shrimp" was like a kite in the strong wind, being blown left and right and spinning wildly.
"Retract the rope, hurry up! It's too late." Ling Hao yelled at the top of his lungs. Yang Xueting pulled the handle of the winch tightly, and the entire boat body made a "creep" sound. In such a violent environment, "Pipi The "Shrimp" was running at full power, and with the help of the winch pulling the steel cable, it continued to dive downward little by little, and the distance to the entrance of the cave was also constantly shortened.
On the seabed at the bottom of the cave, Shi Si was so frightened by Ling Hao's shout in the communicator that she jumped three feet high: "What is the boss doing?" She pouted and muttered, but she never questioned Ling Hao's words. After passing, the "Stone Crab" was immediately launched, the support frame was retracted and suspended, and the eight propellers rotated at the same time, pushing the huge "Stone Crab" to slowly start to retreat along the path it came from.
"Where are we going? Aren't we going to teach them?" Several students came over and questioned her behavior.
"Our boss asked us to evacuate immediately." Shi Si didn't even look at them.
"Why? We need an explanation."
"My boss's order is to explain. When you were chased by a shark just now, did I have to explain to you before shooting? Shut up and sit tight. If you don't want to leave, you can go out. No one will stop you." Shi Si She is domineering and does not give any face to these top students from prestigious schools. In her eyes, these people are scum.
The "Stone Crab" had begun to evacuate at full speed, and the students were still planning to say something back. At this moment, the seawater shook violently, and a huge fireball suddenly appeared above their heads. Then the water pressure surged, and the "Stone Crab" was directly thrown away. "Crab" was so crushed that it hit the seabed. Several students were so shocked that they sat down on the ground, looking at the horrific scene on the skylight, they turned into dumb ducks.
Shi Si frowned and chewed the lollipop in his mouth with a "click". A strong feeling surged into his heart. He hugged the joystick tightly with one hand and tapped the inflation and drainage button with the other hand. The "Stone Crab" dragged out a deep ravine on the seabed, raised up a cloud of sand, floated up again with difficulty, and continued to rush towards the path it came from at full speed. Shi Si was so smart. When he saw the explosion above, he had already estimated what chain reaction would follow. Although she was trying her best to escape with everyone, she was worried about Ling Hao and the others. No matter how she thought about it, she felt that the other party was in danger, and tears had begun to well up in her eyes.
Zuo Pengfei patted her shoulder and said: "Don't worry, Ling Hao and the others have experienced many strong winds and waves, and they will definitely be able to avert danger. We will stop and wait for them when we reach the bottom of the Blue Cave."
"No, don't forget, there is a torpedo at the bottom of the water here. No matter what caused the explosion above, in this closed environment, there is no outlet for the energy, and it will definitely blow up the seabed above. . Even if the torpedo is not detonated by the water flow caused by the explosion, if the collapsed rocks above fall down, it will inevitably explode. Maybe the entire blue hole will be blown up. Don’t forget, there is still water above your head over there. There is an 'Iraqi' submarine, and it is still unknown whether we can surface alive." Shi Si's voice was very low, but it was undoubtedly a bombshell to everyone, and many people were frightened. .
"Then boss and the others..." Yuan Bing spoke anxiously, but he swallowed back half of his words. "Are you dead?" Who can say this? Shi Si's face turned even more ugly, and a line of tears silently fell from the corners of her eyes.
10 meters, with 10 meters left, Yang Xueting began to let out a dull roar in her throat. With a "click", a short spear was pulled out of the rock wall, and the only two remaining ones were in danger. "You bastard, hurry up!" Yang Xueting roared angrily, and the "Pippi Shrimp" was still approaching the entrance of the cave unfaithfully, 8 meters, 5 meters...
With a "boom", a water column of more than ten meters high suddenly rose on the calm sea, less than 200 meters away from the diving ship parked directly above the blue hole. Although the huge wave failed to overturn the ship, it also directly washed it away. It drove a few hundred meters away. Everyone on the boat was soaked by the "heavy rain" after the water column fell, and they all collapsed on the deck in a daze.
The seabed at the top of the cave was blown down without any accident, and this "lost world" left over from the Cretaceous Period would be completely destroyed. Countless huge limestone blocks were wrapped in dark clouds of sand, and the tops of the caves poured down. , there are no blind spots and nowhere to hide. Perhaps 75 million years ago, similar species of these Cretaceous creatures probably experienced similar scenes during the mass extinction. Hidden for endless years, they still did not escape the same fate. Perhaps this is the secret of There must be something deliberately arranged.
3 meters, 2 meters, the "Pipi Shrimp" is getting closer and closer to the entrance of the cave, and the "dark cloud of death" above their heads is getting closer and closer. With a "click", another short spear was pulled out of the rock wall. Seeing that the lives of Ling Hao and the other five people were hanging on this last two-finger-thick steel cable.
"Hold on!" Ling Hao and Tian Yong both roared. At the critical moment, the "Pipi Shrimp" finally dived into the entrance of the cave. Almost at the same time, the outside of the cave entrance was filled with sand and the sound of falling boulders could be heard.
At this moment, the steel cable that was a life-saving rope immediately turned into a noose around everyone's necks. I don't know if it was caught on something, but it almost pulled the "Pippi Shrimp" out of the cave just now.
"Cut the cable!" Tian Yong shouted. Ling Hao found a handle under the console and pulled it hard. With a "bang", the explosive bolt cut off the steel cable. At this moment, the tail of the "Pippi Shrimp" was away from the cave. The mouth is already less than one meter long.
Ling Hao and others breathed a heavy sigh of relief at this time, and before they knew it, cold sweat was flowing all over their faces.
The searchlight shined forward, and the expressions on Ling Hao and others' faces, who had just smiled, all froze. Although the entrance to the cave is quite large, the stalactites and stalagmites inside are intertwined, making it impossible for the "Pipi Shrimp" to pass through.
What is even more ridiculous is that not only do they think this is a treasure place to avoid disasters, but many creatures, driven by a strong desire to survive, burst out their instinctive ancient wisdom and have also taken refuge in this cave.
At a glance, there are spiny sharks, mackerel sharks, coelacanths, and schools of fish of all sizes, all of which are of various species.
"How about we wait until the dust has settled behind and then go out the same way?" Tian Yong asked Ling Hao.
The latter pointed at the monitoring screen: "See for yourself." It turns out that although the dust outside has fallen at this moment, the luminous substances on the rock wall are burning, and they seem to be getting worse. In the blue water, there are actually A wall of fire was burned out, sealing the entrance of the cave tightly.
"It's just a wall of fire, just rush out."
"Nonsense! This is a fire that can burn in water. What if it sticks to the outside of the submarine and burns? Although the outer shell is not scary, the sealing rings are all made of rubber." Yang Xueting gave Tian Yong a rollicking look.
"Let's use the robotic arm to clear the way. Let's get out early. I've had enough of this water area." Ling Hao breathed a sigh of relief, picked up a bottle of water and drank two gulps, then poured the remaining half of the bottle on his face. superior.
The huge boulder that collapsed on the roof of the cave was carried by the sand and finally fell to the bottom of the sea. Unsurprisingly, there was another violent explosion, and the torpedo was detonated. The limestone cave wall, which had already been damaged once, was violently impacted again. The water flow generated by the explosion spurted in all directions. Countless cracks appeared on the cave wall and continued to extend upward. Debris began to roll on the cave wall. are falling, and they are getting bigger and bigger. Not only the Cretaceous Cave and the Blue Cave next door, it seemed that the entire sea area began to tremble.
