"You have to find a way to keep the buoyancy! Try shutting off the air valve! Hold the air in the watertight chamber!" Gen Zhisheng commanded in the channel.

"We've tried, and the problem is with the air valve, and we've lost control of that valve." Caesar said.

Chu Zihang opened the design blueprint of the Dirieste for verification, and confirmed that the problem was the pressure relief valve of the No. 1, No. 2 and No. 3 watertight cabins, which usually does not open at all, it is hidden under the thick compressive armor, and it is very troublesome to detect, but it is such a valve that is not usually used at all There is a problem, which is incomprehensible.

"It was a design flaw, the pressure relief valve was out of order, and all the other valves were closed to prevent air from escaping." "We have tried our best to reduce the speed at which the air escapes."

"I can switch pipes to block the air from the pressure relief valve," Caesar said, "but that would take a long time!" Damn it! Didn't those guys from the Armament Department confidently say that this transformation is a masterpiece?"

"I can try to open the balance rudder first, stabilize the submersible first, and then we can't do anything if we roll around." Chu Zihang said.

"Calling the Diriaeste! Call the Diriaeste! The Rock Flow Institute has a contingency plan, if you can turn on the powerful power source in the Diriaeste, with the stabilizer wing and balance rudder, you can glide in the water! Able to slow down the rate of sinking. But be quick, and in a little while you will fall into the trench and shatter on the seabed!" New instructions came out of the communication channel.

"Are you talking about a strong power source that is a nuclear power compartment installed by the Equipment Department?" Caesar gripped the handrail on the bulkhead and barely stood up, smashing the glass cover on the console with his elbow, and clutching the yellow wrench inside.

Lu Mingfei glanced at the radiation sign on the wrench: "This old antique is actually nuclear-powered?"

"Originally, there was none, and the equipment department felt that the power was too small to complete a large-scale survey during the test, so a nuclear power cabin was installed. So the so-called strong power source is the nuclear power module." Caesar said, "But can you trust the nuclear power compartment assembled by the Armament Department?"

"I'm more convinced that they also added a detonation function to the nuclear power chamber by the way, no, I doubt that this entire submersible can be turned into a bomb if necessary." Lu Mingfei said.

"There are indeed a few experts from Oak Ridge in the armament department who have created the world's first atomic bomb." Caesar said.

"I'll just say explosions are their specialty, right?" Lu Mingfei said.

"At a depth of 6,400 meters, we are still two kilometers away from colliding with the bottom of the abyss, the tumbling has stopped, and the submersible is back in position!" Chu Zihang firmly grasped the steering rudder and the operating lever of the stabilizer wing, "If there is power, we can do underwater gliding."

"Don't worry about your strong power source," Lu Mingfei said loudly, "Director Yuan, you heard, the deep submersible has returned to its normal position, and we have applied to use a safety rope to slow down."

"Roger." Yuan Zhisheng's tone did not change, "I have turned on the safety hook by remote control, and I am expected to use the safety rope to slow down section by section, please be prepared."

"Roger!" The trio replied.

Not long after Yuan Zhisheng's voice fell, there was a screeching sound of metal bending above the cockpit, and the feeling of weightlessness disappeared, replaced by a feeling of overweight with a sharp decrease in the speed of descent, followed by an alternating feeling of weightlessness and overweight, which was decelerating section by section, indicating that the Dirieste was braking step by step.

The depth gauge finally stopped at 7,900 meters, and the Dirieste was hovering in the deep sea with difficulty. The lights on the instrument panel flickered for a moment and then suddenly all went out, and the cockpit was plunged into darkness, and the air and hydraulic oil flowed in the pipes at high speed, making a whistle-like "whine" sound.

Caesar immediately grabbed the flashlight and checked the instrument panel: "The circuits and pipes are still normal, and the No. 4 watertight compartment is still working normally, it is really worthy of being a prototype, and it is still durable."

A childish voice came from the headphones: "Sumeru calls the Diriaeste! How's it going? The equipment is in good shape

Often?"

"There are no problems with the circuits and plumbing, but the power is out." Caesar said.

"It's power outage protection, you check the systems, and if it's okay, you can restore the power manually."

"No problem, everything is normal at the moment." Caesar said after a thorough examination, "This is rare good news."

"I'll call the Executive Department to see if I should immediately return to repair the submersible or adjust the survey plan." Gen Zhisheng said, "Please wait."

"I think we won't be able to return for the time being, but as for the reason, you can see the video we sent back." Caesar had a strange voice.

The trio all noticed that something was wrong with the outside environment, the Di Trieste was in a state of power-off protection, the gas mine outside was also extinguished, and the cockpit should have been pitch black, but there was light shining in from the porthole, it was a warm red light, but this was the deep sea at a depth of 7,900 meters, and it should have been absolutely dark.

But the sea is full of life, the color of the water is as red as the sunset, there are thousands of fish forming a huge school of fish swimming in the sunset water, these fish species are different, some are as white as pure silver, some are almost transparent, some emit a light blue fluorescence, occasionally a huge manta ray fanning the wide fins through the fish, the fish open and close, and the huge turtles swim with the fish.

Most of these fish they had never seen before, and even if they resembled some fish, they were very different, such as the manta ray's head with a black-and-white exoskeleton, and the turtle's back carapace was not a hard shield but fleshy structure, like cracked red basalt.

The scene in front of me seems to be only in a child's dream, the sunset water outside the porthole is like the twilight sky, and the fish seem to swim in the sky.

Lu Mingfei raised his head, there seemed to be gray-white clouds flowing above the deep submersible, and after a closer look, the "cloud" suddenly turned around, its long tail stirred the seawater, leaving a transparent vortex with a diameter of more than ten meters, and the huge body showed its true identity, it was a giant whale with a body length of more than 100 meters.

"It doesn't seem scientific." Lu Mingfei said.

Of course, it's not scientific, there shouldn't be such a big whale in the world, and the largest blue whale can only grow to more than 30 meters, and it's still that sentence, the depth here is 7900 meters, and the strange creatures around, whether it's fish or turtles or giant whales, are not species that move at this depth, and everything here is against common sense.

"It looks like a dead dragon whale, but the dragon whale probably won't grow that big." Chu Zihang said softly.

"You don't have to tell me, I can guess. We're almost finding the embryo, aren't we?" Lu Mingfei said.

"I guess it's that the ecological environment here is too abnormal, which means that there is something unusual in the vicinity that has reconstructed the ecological environment here, and even the marine species we are familiar with have mutated." Chu Zihang said, "We are now above the abyss."

Lu Mingfei looked down from the observation window, and figured out why the sea water here showed this sunset-like red, they were now directly above the Japan Trench, on the left was the gentle seabed of the Eurasian plate, and on the right was the craggy cliffs of the Pacific plate, where they collided to form an extremely deep submarine canyon, and at the bottom of the canyon was a north-south fiery red rift, where the earth's crust was fractured, and there were constantly burnt red rock layers rolled out, and a large number of bubbles formed in contact with the seawater, making a rolling sound like thunder, Not long after the bubbles rose, the water vapor liquefied again.

"That's a wound on the earth." Chu Zihang said, "The earth's crust is fractured here, and the mantle layer is directly exposed, and it is because of this wound that the surrounding geological structure is extremely unstable, making Japan the country with the most frequent earthquakes in the world, and it is possible that one day it will sink into the sea like Atlantis." Dragons would choose such an unbelievable place as a hatchery."

"Hey, senior brother, let me correct you, hatching in this place is not the choice of dragons, it was the embryo that sank here with the Lenin, and there is really no way to hatch here." Lu Mingfei said, "If there is a choice, I guess it itself is actually not very happy to hatch here."

"Fortune

It's not bad, but it actually fell directly into the territory of the ancient dragon, so we don't have to look for it." Caesar said.

"Why are these mutated sea creatures here? Waiting to be eaten by the dragon?" Lu Mingfei said.

"I think there must be a source of food for them around here," Caesar said, "and a lot of natural fishing grounds are rich in microbes carried by ocean currents, and you can see schools of fish swimming in those places, which is usually either mating or migratory or having tiny microbes in the water for them to survive."

"Oh, I know, I've learned it in geography class, but these mutated creatures obviously took generations to adapt to such deep waters, and even if there really is a lot of plankton here to form a natural fishing ground, what attracted those "first" creatures? It's not a good environment for them at all." Lu Mingfei nodded.

"Then there's another possibility, which is that the embryos release pheromones that lure these schools of fish, attracting the 'prima' fish to come here and breed from generation to generation as food reserves." Caesar said.

"The Lenin sank twenty years ago, right? So the dragon had been preparing this meal for almost twenty years? We're not here to deliver food to it, are we? When the time comes, we sneak in front of the ancient dragon who has been hungry for twenty years, twist his delicate body and say, Master, what do you want to start eating first? Fish? Submarine? Still is...... Me?" Lu Mingfei said.

"It's a pity that we didn't prepare a maid outfit, otherwise you would just squirm alone, it will vomit directly, and you won't be able to eat anything, so we can escape." Caesar was very good at picking up the stalks.

"Strange! The fish are suddenly gone!" Chu Zihang, who had been observing the situation outside, said.

The surrounding sea suddenly became empty, and the fish that had been swimming happily all of a sudden disappeared, leaving only the sunset water around them.

"Something must be coming." Caesar suppressed his smile and said.

"That's the one, right?" Chu Zihang pointed to the observation window on the right.

A slender black shadow swam in the water on the right, its long tail swinging slowly, moving calmly, but surprisingly fast, almost like a torpedo rushing towards the target. It was a hammerhead shark, just surprisingly large, not the size of this species, it was about the length of a whale shark.

"That's probably the most ferocious predator in the sea," Caesar whispered, "and it consciously avoids other creatures when it appears, and it often happens in the fishing grounds, and when the direction of the fish swims changes, it means that something big is coming."

Lu Mingfei was unimpressed: "I thought there was a dragon, but it turned out to be an ugly shark."

The giant hammerhead shark sped up sharply, and a few seconds later it was near the submersible, and it seemed to be intrigued by the strange thing it had never seen before, and moved one eye to the center of the observation window to look inside.

"Hey! Don't mess around, boy! We are all human beings with high cholesterol and fat content, and eating it is not good for your health and cannot be to your taste, and junk food is not to be eaten!" Lu Mingfei said angrily.

"You can rest assured, there should be no species in the ocean that like to eat people, just like you said, the nutritional composition of humans is not a delicious food for hammerhead sharks, and the food it likes should be something that is big enough and fresh and healthy like the overlord squid, and it must have the taste of seafood sashimi." Caesar said.

"Is the overlord squid you are talking about very large and has a lot of tentacles, and there are a lot of suckers on the tentacles?" Lu Mingfei said.

"The overlord squid has ten tentacles, each of which is as powerful as a python, and can fight the sperm whale, someone has found a sucker-like wound with a diameter of forty centimeters on the sperm whale's body, and it is estimated that the tentacles of the overlord squid that fought with the sperm whale may be sixty meters long." Chu Zihang said.

"At this time, you're still interested in discussing the Overlord Squid?" Caesar said.

"I'm just more concerned about seafood that people can eat, and occasionally I learn about seafood that can eat people. Look over there, is it the overlord squid you are talking about?" Lu Mingfei pointed forward.

Caesar and Chu Zihang froze, moving slowly in unison

Turned. Outside the observation window in the back was a huge, blue puck-like eye, and in the water beside it, huge wrists and feet were dancing restlessly, covered with suction cups half a meter in diameter.

"It's an overlord squid." Caesar whispered.

"Over sixty meters long." Caesar also whispered.

"I kind of understand what it means to be a phobia of the deep sea." Lu Mingfei said.
