Dragon Clan: Thought So Far

Chapter 350 341. Ghost-Toothed Dragon Viper

A dazzling red light suddenly began to flash on the sonar screen, and at the same time, the operating panel of the underwater drone also flashed a red light. The cabin surrounded by pipes and circuits was filled with an anxious and panic-inducing red light.

The Trieste was sounding a silent warning.

The cockpit of the deep submersible is small and compact, and the internal space is only about the size of a civilian elevator. It can fit Chu Zihang and Caesar without being crowded.

At this moment, the elites of the academy held their breath at the same time and threw themselves nervously in front of the operating table.

"What's the situation over there?" Chu Zihang's palms were sweating, and he raised his head to look at the dark, snowy sea outside the window.

He still needs to ensure that he has control over the old antique to avoid the disaster that may occur if EVA's contact is suddenly interrupted and the remote control system fails.

"UAV No. 1 has been destroyed...medium-sized target, rapidly approaching, speed 25 knots, 61.5 degrees, depth 2100 meters!" Caesar squinted his eyes and stared at the sonar screen,

"Exclude submarines, exclude torpedoes, the infrared response is high, and no radio signals are received at the same time, it must be some kind of creature! Judging from the last video transmitted back by the No. 1 drone, that thing should be a shark! One with a wide mouth A super shark that can reach over two meters!”

Shark teeth are arranged in layers in the mouth, with hundreds of teeth in each layer. The outermost teeth are used for hunting, while the inner teeth are used as backup.

When the outermost teeth are lost or damaged, the inner teeth move forward along the gums and take their original positions.

Both Caesar and Chu Zihang had taken marine biology as an elective in college, and had systematically studied the physiological structures of most marine creatures, including sharks.

But when Caesar said this, Chu Zihang was still stunned for a moment. He didn't understand why the dragon subspecies would attack their drone.

The vast majority of marine life are completely uninterested in bathyscaphes, submarines and even divers. They are neither afraid nor curious, and are simply ignorant.

What's more, the materials used in the drones manufactured by the Equipment Department are strong titanium alloys, ceramics and new composite materials carbon fiber.

The thing is also completely silent when sailing in the deep sea. It has excellent shock-absorbing design, curved-angle-filled alloy shell, shock-absorbing floating raft installation of multi-stage underwater propulsion motors and the use of pump waterjet propellers instead of traditional propellers. These features make The drone's noise level is controlled to between ninety and one hundred decibels, even lower than the background noise of the ocean.

This is probably the equipment department's most proud design in recent years.

It's hard to imagine how the shark, which was eroded by dragon's blood, discovered the slowly sinking drone.

"We don't need to worry. The size of the Trieste reaches 15 meters, and the whole body is wrapped in a super-strength alloy shell. The shark is just a medium-sized target for us, and it cannot pose a threat to the deep submersible. "Caesar quickly calmed down.

It was just a subspecies corroded by the blood of the ancient species. They even fought against the real corpse guard made from the corpse of an ancient dragon at Genji Heavy Industries.

How could a god-hunter be afraid of wild beasts?

"But if its target is really this deep submersible, then maybe we should re-make the dive plan." Chu Zihang said, "Is there anything that doesn't want to see Delia carrying nuclear bombs and alchemical sulfur bombs?" The Sturt went to the depths of the Abyss."

Caesar's face turned gloomy for a moment.

Wild animals have the instinct to seek advantages and avoid disadvantages, and so do humans and dragons.

However, humans call this strange ability the sixth sense, while dragons call this ability to sense danger "spiritual sense."

Just like you point a personal rocket launcher at a fifth-generation species that has just woken up from a deep sleep. He may not belong to this society at all, and his recent travels are only in the Middle Ages, but he will still instinctively want to escape from the rocket launcher. Aiming range.

Because death was slowly spreading over his body like cold sea water.

Perhaps the ancient dragon embryo that was sunk into the deep sea with the Lenin in the depths of the abyss has completely awakened. That thing was dormant in the dark abyss waiting for the recovery of its power, but it felt that Dilieste was carrying a deadly weapon. The trumpet fell from the sky, and a subspecies was sent or intimidated to destroy them.

"Stop the engine first," Caesar said.

Chu Zihang understood and immediately started to shut down the engine system of the Diryste. The big black steel fish began to glide silently in the deep sea.

Caesar also fumbled to turn off the power and screwed on all the valves at the same time.

In the deep sea, human submarines rely entirely on hearing to move, and so do the animals.

The cabin of the deep submersible quickly became silent. At the same time, the situation here has been informed by the executive department. Once it is confirmed that the dragon in the abyss has awakened and completely mastered the new ecosystem, the college will have to carry out the blasting plan. Temporarily abort and immediately pull the Trieste out of the water.

Of course, an alchemical sulfur bomb or a nuclear bomb could easily destroy an incubating embryo that was placed on the seabed and unable to move, but it had no ability to kill a fast and dangerous dragon.

In this case, Operation Jiyuan has failed. The only thing Principal Angers and Professor Schneider can do is to pull Caesar and Chu Zihang up from the water two thousand meters deep with their tin cans. Avoid more meaningless sacrifices.

Chu Zihang pursed his lips tightly, which made his lips appear extremely thin and the shadows on his facial contours extremely deep.

He glanced at Caesar and found that Caesar's expression was almost the same as his.

Both of them were trying their best to restrain themselves from making any sound, and the cabin was as quiet as the other side of the world.

This is also the rule on the submarine. When sailing silently, all passengers must remain silent and can only communicate with eyes and gestures.

The Trieste itself is a hollow metal shell, which is an excellent conductor of sound. The same is true for seawater. The extremely subtle sound in the submarine will be amplified hundreds of times in the seawater.

No one knows whether the mutant shark has evolved a powerful biological sonar like a whale, but Chu Zihang and Caesar are unwilling to take risks.

The active sonar has been turned off by Caesar. Now they can only use passive sonar to scan the surroundings, but this will reduce the range of the submersible.

Now they must wait until the shark pushes away the shock wave of the seawater and touches the Trieste before they can detect the approach of the thing.

Ten minutes have passed since the destruction of the No. 1 drone. According to the speed of the mutant shark detected by Caesar through sonar, they should be able to connect soon.

The sonar screen was originally blank, but suddenly an object with red light was rapidly approaching the Trieste.

Chu Zihang's brows knitted together.

Here it comes, is that thing really targeting them?

The sea outside the observation window was suddenly stirred, and the dense sea snow originally fell from above, and now the sea water became turbid, and the clumps of organic matter were torn apart by the transparent vortex.

Both of them subconsciously held the fixed rails beside them to prevent themselves from being knocked out of the seats in the upcoming impact.

In the sea water illuminated by the gas, a majestic black shadow suddenly came from afar! Its long tail swung violently, and it was like a ferocious fish when it moved!

It was indeed a shark corroded by dragon blood. It was huge, nearly ten meters long, with two strange eyes with a faint golden color, and the surface of its body was not smooth fish skin, but covered with metal-like scales.

It was obviously this thing that destroyed the No. 1 drone released by Chu Zihang.

Its teeth were sharper than a reamer, and it crushed the alloy forged machine into pieces with one opening and closing.

When approaching the Trieste, the shark, whose original species could not be identified, suddenly accelerated and passed by the submersible with turbid sea water.

It was obviously not interested in this strange thing at all. The sonar screen showed that the shark's cursor was getting farther and farther away, and it disappeared completely outside the detection range a few seconds later.

Chu Zihang and Caesar looked at each other, not understanding why things turned out so disillusioned. They had even prepared for the impact. Although the speed and power of the shark would not cause a devastating blow to the Trieste, it would inevitably cause accidents in the airtight compartment and the watertight compartment, and this operation would end.

But that thing actually passed by them like this.

Why did it destroy the No. 1 drone?

Sharks are not as smart as dolphins. They will not find something to do on the road out of curiosity or interest.

Every action of each shark is purposeful and targeted.

"The danger is temporarily lifted. Release the No. 2 drone to continue diving and exploring." Chu Zihang pressed the microphone and informed the executive department of his next move.

"Please continue the mission." Cheng Shuangfan's voice sounded, the engine was restarted, all the valves were opened, and Caesar also turned on the power in the cabin.

At this time, the two of them realized that they were completely soaked in cold sweat. Obviously, even if the president of the Lionheart Club and the president of the Student Union were heroes who could carry knives and kill into the dragon's lair on land, they still deeply felt the insignificance of human power when they came to the seabed two thousand meters.

"Minimum thrust cruise, full left rudder, and dive at a constant speed."

Chu Zihang followed the instructions of the operating manual to let the watertight compartment of the submersible absorb seawater, so the entire surface of the Trieste appeared with tiny bubbles, and then slowly sank into the deeper sea.

"But..." Caesar looked at Chu Zihang dimly,

"Why does it go up there?"

As a fish, sharks mainly breathe through gills. This animal uses gills to filter oxygen in the water during swimming to exchange oxygen.

Therefore, sharks do not need to surface to breathe like whales or dolphins. Theoretically, a megalodon that has been mutated by dragon blood can swim in the deep sea for its entire life.

Moreover, the nearby seas are so barren. Apart from the ecosystem shaped by the gene leakage of the ancient dragon embryo, where should a ten-meter-long giant marine predator find enough food to survive?

Chu Zihang's pupils shrank slightly, and the uneasy flames jumped in his never-extinguished golden pupils.

The noise of mechanical operation filled the entire cabin of the Trieste. The No. 2 drone had been released, and the screen reappeared the picture transmitted back by the underwater camera.

The submersible followed the No. 2 drone and dived together. The surrounding sea snow began to become quiet and peaceful again, as if everything that had just happened was just a dream.

But at this moment, the hearts of the two people in the cabin were shrouded by a huge shadow.

"It's... running for its life." Chu Zihang exhaled deeply.

The demon sword Murasame lay on his knees, and at this moment Chu Zihang's right hand had already grasped the handle of the long sword.

Although everyone knows that a Japanese sword is useless at the bottom of the sea several thousand meters deep, he still wants to hold it tightly.

Holding Murasame tightly means holding strength, and he will no longer be afraid.

It can be imagined that even in an ecosystem based on the leaked genes of ancient dragon embryos, the huge shark covered with hard scales is definitely the top predator. In the deep sea, even some pure-blooded dragons are not its opponents.

In the depths of the abyss, it can enjoy powerful gene fragments and can also sit on almost all the lower creatures of the entire ecosystem as its lambs, but it still chooses to escape, and flees so hastily that it even smashes the drone that accidentally appears on its way forward as an enemy.

What can make such a predator so scared that it even gives up the dignity of food and territory?

Suddenly, a silver shadow flashed in the video sent back by the No. 2 drone, and Caesar even thought that he had made a mistake just now.

But then more and more shadows flashed in front of the camera, and Chu Zihang and Caesar were stunned.

It was like a group of fireflies rising from the depths of the ocean, or a huge number of stars rising into the sky.

It turned out to be a slender fish, covered with beautiful silver-blue scales, and the light came from a slender tentacle on their heads.

There were thousands of them, glowing with a faint blue light, like a vortex of starlight.

"It's a ghost-toothed viper..." Chu Zihang's voice was hoarse.

This thing was once considered by the academy to be a non-existent fantasy creature, but now they appear in groups above the abyss, chasing the top predators in the deep sea all the way to the surface.

The teeth of the ghost-toothed viper are sharp and hard, and can even bite through steel. In the ancient era of the gods, they were used as executioners to kill and torture pure-blooded dragons.

A mutant shark is just food in front of these monsters.

But fortunately, this thing does not act by hearing but by smell. The drone and the Trieste are just lifeless stones in their eyes.

In front of the camera, a silver river rushed through the black ocean. A few minutes later, silver dots of light bypassed the Trieste like a whirlpool and continued to chase the smell of sharks upward.

"The genes of these things are very unstable. They must continue to ingest the gene fragments of the dragon race for a long time to avoid death, so they will not spread from the abyss to the entire Pacific Ocean." Caesar said, looking out of the observation window. Even though he didn't smell anything, he still felt the bloody smell coming.

"But it's strange. The original purpose of the dragon race to create the ghost tooth dragon viper was to serve as the guard of those towering cities, so they should not be as far away from their habitat as they are now."
