Doomsday: I Build an Infinite Train.

Chapter 452 The Cliff, the Nuclear Explosion!
Empty!
Water pressure, collisions, and metallic clanging filled the entire Mugen train carriage. The dark seawater was murky, and outside the porthole, one could only see the bodies of huge, black and white sea serpents that appeared from time to time, gradually becoming thinner as they descended.

Countless planktonic organisms emitting a ghostly green fluorescence began to appear densely in the deep water, making it clear that the train was rapidly descending.

"Lane, the descent is too fast. If it hits any pressure hull, it could cause distortion."

"If we rushed straight into the super vortex array at that speed, we might all disintegrate!"

Behind the Infinity, the Abyss nuclear submarine, carrying hundreds of members of the Falcon Fleet, rapidly descended at an angle. Its ballast tanks were full, and the descent speed had reached its limit. Various alarms blared throughout the submarine. However, Ryan hesitated without hesitation, staring at the target on the monitor screen and decisively giving the order.

"Don't worry about anything else, stick close to Lin, we only have one chance!"

Rumble!
The continental shelf was trembling, the seawater was boiling, the submarine base was collapsing on a large scale, and the boiling lava in the geothermal well completely submerged and swallowed the release device of the Deep-3 core heat extraction device. Lava rushed into the base's passages and laboratories, and everything was burning and exploding.

The sky was already dark, the black canopy almost merging with the turbulent sea, making it impossible to distinguish between night and the ocean.

Onboard the Infinity, the near-vertical descent kept everyone on edge. The full-speed descent caused the special metal pressure hull outside the Infinity to emit a metallic groan, with a continuous 'thump-thump-thump' sound. At this moment, everyone in the carriages was on tenterhooks.

The first stage involved descending to a depth of 2260 meters below the abyss cliff.

The second stage involves entering the underwater super vortex array within the Tranquil Abyss Vortex Channel.

If the Infinity and the nuclear submarine are not torn apart by water pressure or underwater monsters in the second stage, the third stage will be to ride this deep-sea current and break out of the sea rock island area.

However, at this moment, the Infinity, marked with a Level 4 designation, seemed to become a beacon in this dark sea, ignoring the terrain, attracting both those on the islands and the sea monsters in the deep sea.

Therefore, what Lin Xian needs to do is to use the core heat device to detonate a high-energy core wave, eliminate the strange entity, use a larger 'lighthouse' to divert the strange entity's target, and then use the dimensional bubble of the Silver Dragon Ten Thousand Mistakes to complete a magic trick of 'disappearance' amidst the surrounding of billions of sea monsters.

Lin Xian knew his idea was very bold and might be difficult to achieve such a perfect result, but there was no room for consideration at the moment. Detonating the geothermal well was the most likely solution to work. At this moment, Ding Junyi's words made Lin Xian's heart skip a beat.

flowering?
Are you kidding me? Silver Dragon, please don't cause any trouble at this time.

"What does 'bloom' mean?!"

Ding Junyi didn't speak. She directly raised her hand and controlled a vine to send the Silver Dragon Ten Thousand Treasures Plant to Lin Xian's front. Lin Xian looked at it and saw that the purple light inside the roots of the Silver Dragon Ten Thousand Treasures Plant was more dazzling than before. At the tip of its uppermost leaf, a white flower bud the size of a fingernail had grown.

This flower bud was noticeably different from the one in Star Abyss No. 5. Some kind of geometric fragments of light seemed to flow on the petals, like a projection of some dimensional space. Moreover, in Lin Xian's vision, several petals of the flower bud were slowly unfolding. He focused his gaze on the center of the flower bud, only to see that its interior was completely black. Just by looking at it, Lin Xian inexplicably felt that the black center of the flower bud was constantly expanding, as if it was about to suck him in. And in the depths of that darkness, there were countless points of light from the universe.

13...

12...

At that moment, Lin Xian did not notice that the time on his watch began to slow down, and he began to sink into the darkness, with a large number of images flashing past his vision.

A colossal explosion that changed the very fabric of the world, a giant mushroom cloud illuminating the ocean, churning sea monsters, the shadowy silhouette of a giant ocean god in the vast sky and sea, a super vortex of black currents, screams from inside the Infinity Ship, the ticking of a clock, a metal die that keeps repeating the numbers 5 and 6, a countdown on the retina reaching 00:00:01—at that very second, blood engulfed everything…

hiss!
Lin Xian suddenly snapped out of his dark illusion, took a deep breath, and looked at the countdown timer he had set.

15...

14...

what happened?

Before their eyes, the strange buds of the Silver Dragon Ten Thousand Mistakes were slowly opening, and at the same time, Ding Junyi's voice came through.

"I am not clear about the results of stimulating a more mature or advanced state of disaster-caused plants than flower buds."

Lin Xian frowned and looked at Ding Junyi: "What do you mean? So, can we use it now or not?"

"can."

"Well!"

"Lin Xian!!!" Lin Xian grabbed the Silver Dragon Ten Thousand Mistakes, and KIKI shouted through the earpiece: "We're about to plunge into the deep sea cliff!"

[Danger! I have detected a large number of biological signals in the waters outside the channel.]

13, 12…

Lin Xian's heart sank: "How many?"

Beep! Viola simultaneously displayed a sonar image on Lin Xian's power armor holographic screen. After the circular scanning path, the entire screen turned blood red!
Empty!
The Mugen train collided with a turbulent underwater current, causing the entire train to tremble violently. The deep-water port below the island was a steep, dark slope. In the deep-sea cliff area, there was an extremely narrow ridge valley where a huge ocean current would suddenly accelerate, sucking seawater directly into the abyss below.

It was precisely because of this natural terrain and ocean current environment that the original Federation established a secret submarine base here, from which they could silently enter the 1000-1200 meter deep water layer.

"This is not good!"

"What should we do? Should we fight our way out together?"

At this moment, Ning Jing, Qian Dele, and others could be heard talking together.

“I can freeze a section of seawater to create an environment for us to dive. Once we get into that whirlpool, we might be able to shake it off,” Ryan’s voice came through the communication channel.

"Lin Xian, we'll be out of the tunnel in 300 meters!" Chen Sixuan shouted.

The beeping of the watch continued incessantly, signaling that it was getting dark.

"Never mind that, everyone get ready for the impact. Ryan, you guys just stick close to Infinity!"

7...

In carriage number 3, Lin Xian shouted, grabbed the Silver Dragon 100,000-fold incubation pod, and flew towards the cockpit, adjusting the thrusters of his power armor as he descended.

At this moment, several green vines grabbed Lin Xian and the silver dragon, stabilizing them. Ding Junyi controlled the green vines as if they were her own limbs, quickly approaching them and coldly speaking to Lin Xian.

"let me help you!"

Cluck cluck cluck! At this moment, Ding Junyi controlled the green vines, which quickly built a smooth passage inside the carriage like countless flexible tentacles, and then followed Lin Xian towards the cockpit.

Seeing this, KIKI from carriage number 2 immediately followed.

"Ryunosuke, go to the back of the train and keep the Mugen and the people inside steady!"

Upon hearing this, Ryunosuke immediately used his telekinesis to fly rapidly towards the carriage above.

Lin Xian skipped carriages 1 and 2 and entered the lowest driver's cabin. Chen Sixuan, clad in battle armor, was firmly secured to her seat. Viola, who was controlling the train, pointed to the colorful giant snake that flashed past the porthole as Lin Xian entered.
"We're almost at the bottom of the cliff, but this monster is blocking the entrance. There are definitely a lot of other strange creatures blocking the way outside. What do we do?!"

"Let's just charge!" Lin Xian gritted his teeth. The sound of water explosions roared ahead, and the entire Infinite train trembled under the high pressure.

"It's about to explode, KIKI! No matter what you see, smash it open!"

"Okay!" KIKI responded loudly, her entire body bursting with psychic power, and the surging waves caused her body to begin to radiate a luminous glow.

"Director Ding, the countdown is over. Immediately expedite the release of 100,000 Silver Dragons."

"clear."

Empty!
The water was turbulent, and the speed at which the Infinity was descending was still increasing, soon exceeding 900 meters and then 1000 meters.

In sight, the giant black and white sea serpent's body stretched downwards like a pillar reaching the sky, its diameter beginning to narrow, seemingly about to reach its tail.

At this moment, the turbulent eddies made the seabed and cliffs murky. The Infinity plunged into the murky water, and the lights outside the portholes disappeared instantly, leaving only darkness. At this time, the Infinity continued to descend rapidly, relying solely on the detectors and Viola's precise all-around control.

With a deafening roar, the Infinity began to tremble violently. The entire train seemed to be churned in a whirlpool, and the people inside felt dizzy and disoriented, with explosions occurring repeatedly. Lin Xian knew that the Infinity was currently rushing out of that vortex with its enormous suction force. His heart tightened, and he stared intently at the time.

Suddenly, the violent tremors stopped abruptly, and the explosions inside the vehicle vanished. The Infinity emerged from a murky current and entered a calm body of water. The Infinity's near-vertical descent began to stabilize, and only then did they truly enter the deep waters of the Pacific Ocean!

"Lin Xian!"

With her keen observation skills, Chen Sixuan suddenly spoke in a low voice. The sonar system alarm sounded a sharp bang. The group, who had regained their footing from the violent tremors, looked out through the Starry Sky porthole. Instantly, everyone's aura froze!
In the pitch-black sea, countless shadowy outlines covered the entire area. The lights of the Infinity ship shone only on a patch of bony spikes shimmering on the edge of its fins. Deeper in, countless whip-like tentacles swayed like a sea forest.

Perhaps there is one or some other creature, or perhaps there are countless of them. The sonar system is completely blood red, making it impossible to see their full appearance or distinguish their types.

At this moment, the Infinite and the Abyss nuclear submarine, which rushed out of the turbulent current, were like earthworms floating in front of a group of deep-sea behemoths, stared at by countless abyssal eyes.

drop!
In an instant, the spirit level monitoring devices on everyone aboard the Infinite and the Abyss-class nuclear submarine simultaneously went off.

Level 5 marking!
Everyone is locked down!
At this moment, Lin Xian felt a chill run from the soles of his feet to the top of the furnace. He had no time to consider whether there were any S-class beings in the abyss ahead, or whether they were marked as level 5 because of the numerous special-class beings.

Lin Xian looked at Ding Junyi. At this moment, the flower bud on the Silver Dragon Ten Thousand Ingot had fully bloomed, and the time on Lin Xian's watch also returned to zero.

3...

2...

1...

Beep! At the same time as the time on Lin Xian's watch ended, so did the detonator of the space-based weapon that Lin Xian had placed above the reactor.

In an instant, the molten titanium alloy shell of the Deep-3 core heat extractor emitted a final, blinding blue light amidst the magma, and the superconducting ring of the Hyperion directional confinement gun abruptly contracted! The chain reaction device implanted in the reactor core was instantly activated, and the fusion energy released by the honeycomb fuel rod array broke through the critical point in a fraction of a second—

On the island, a golden-white star suddenly shone brightly in the black sky and sea!

There was no sound, only a blinding light that illuminated almost the entire world.

Centered on the geothermal well, seawater within a radius of 1.2 kilometers was forcibly drained, forming a vacuum bubble with a diameter of one kilometer.

The swarm of sea-dwelling worms and snakes, along with countless bizarre creatures burrowing into the earth from the sea rock prison, were vaporized directly at a temperature of 1.7 million degrees Celsius. The lava flow from this geothermal well was pushed back into the mantle by the fusion shockwave.

The entire island began to vanish from the middle like a sand tower. The rubble that splashed up when the prison walls collapsed was vaporized into sulfurous clouds in mid-air. It was then carried back into the vacuum zone by the steaming seawater with high heat radiation, forming a ring-shaped tsunami wall that was thousands of meters high.

This enormous star over the sea directly cleared a huge hole in the sky, creating a massive canopy. From high above, one could see countless sea monsters and strange creatures approaching the island being instantly annihilated, spewing out a ring of black mist that dissipated from the sea surface.

Rumble!
The moment the fusion fireball contracted, it triggered a secondary fusion of deuterium and tritium. A pulse-like shock wave propagated at high speed along the mid-ocean ridge of the Pacific Ocean. The seabed rock layers shattered and rose like an eggshell. The huge shock wave was transmitted through the seawater and the seabed, and within seconds it directly impacted the cliff seabed in front of it.

At that moment, the Infinity and the nuclear submarine, which were floating in the deep sea, were like capsules being shaken in a water bottle. In an instant, they were pushed down the cliff, and at the same time, the dense sea monsters in the cliff were also washed away.

"what!!!"

Screams filled the air inside the Infinity, which was being turned upside down by the seawater. At this point, people could not tell which way was which as they were swept away by the terrifying current. Through the portholes, it looked as if the Infinity was rushing past all sorts of terrifying abyssal monsters.

A vortex-like gaping maw, fin edges resembling mountain ridges, compound eyes of some kind of multi-segmented giant ringed creature…

Lin Xian held Chen Sixuan tightly. At this moment, the entire cockpit was stabilized by Kiki's telekinesis. Behind them, Ryunosuke also used his superpower to protect the passengers in the car from being torn apart by the huge churning force.

In that instant, Lin Xian seemed to hear all sorts of strange cries, some like the howling of an abyss, others like the rumbling of the earth's crust. He raised his finger and pointed out the porthole, ready to use the gravitational lens at any moment.

Under the rotating headlights, a gigantic maw, covered with spiraling teeth like a volcano's crater, hurtled straight toward the Infinity with immense water pressure and suction, as if it wanted to swallow them whole.

Lin Xian's eyes flashed with anger, and he immediately prepared to attack simultaneously with Kiki.

Unexpectedly, in the next instant, several giant, deep red vines crackling with lightning stretched forward at a visible speed, growing rapidly from half a meter to several meters in diameter. Each vine was thicker and larger than the Infinity Ship. The vines spiraled out and smashed open the abyss's gaping maw, even using the force to push the Infinity Ship off the cliff below.

Lin Xian suddenly turned around and saw that Ding Junyi's eyes were flashing with a faint green light. The blood vine had somehow grown out of the cabin of the Infinite.

Without having time to think about what had happened, Lin Xian made a decisive decision.

"Director Ding, now is the time!!"

With her left hand controlling the blood vine and her right hand controlling a thin green vine to reach into the silver dragon's 100,000-fold incubation chamber, Ding Junyi gently plucked the open flower.

puff!
In an instant, everyone on the Infinity, including the nuclear submarine, seemed to feel the boiling sound of the seawater disappear, and at the same time, they heard a slight sound of bubbles bursting in their ears.
