Apocalypse: I Built the Infinite Train-Chapter 454: The Super Whirlpool

At this moment, after understanding their current predicament, everyone aboard the Infinite and the Northern 09 nuclear submarine tensed up, silently sweating with anxiety.

The thrusters were reduced to their minimum speed as the two submersibles began moving toward the cliff ahead at their slowest cruising pace.

The mud rising from the seabed had turned the entire sea area into a turbid hell. The Infinite advanced slowly relying on its detectors, and in the cockpit, Lin Xian and the others all wore grave expressions, as if they could hear their own heartbeats.

Beep.

The sonar detector sounded.

The terrain scan continuously mapped out a holographic seabed topographic map. A smooth underwater cliff slope descended downward, increasing the depth.

In the rear carriage, Shiori and A Bai, who could sense the monster's aura, looked extremely panicked. They were acutely aware that a terrifying evil god-like colossal beast stood in the abyss ahead. Neither submersible, including Viola's detectors, could truly gauge the monster's actual scale. The heavy train and the North Wind nuclear submarine were like two insignificant earthworms at the foot of a mountain. In Shiori and A Bai's perception, this was the first time they had directly sensed such a world-ending behemoth that blotted out the sky.

Its aura felt like the sky collapsing and the sea overturning.

And they were now advancing toward this monster!

In the Infinite's cockpit, Lin Xian's entire body was tense. He focused all his attention on the Mechanical Heart, and at this moment, the Infinite seemed to merge completely with him. He could clearly perceive the bone-chilling pressure outside the cabin and the eerily flowing underwater currents.

Beep.

The sonar detector sounded again, issuing an alarm—not a biological alarm, but a terrain alarm. The terrain scan analysis indicated that ahead was a sea cliff, a mountain mass.

But Lin Xian knew that ahead should be a bottomless abyss.

Boom!

Massive impact currents surged continuously from behind, as if invisible hands were pushing them toward the sea cliff, toward the abyss.

"Is that thing standing at the bottom of the trench abyss, or is it rising?" KIKI hovered beside Lin Xian, speaking cautiously.

Lin Xian shook his head, not daring to be distracted at all at this moment.

"Viola, help me find a descent path."

【Descent path has been mapped through terrain scanning.】A clear holographic image appeared before Lin Xian. The area before the sea cliff was filled by a massive bodily structure. Viola found a relatively wide hollow area in the cliff and charted a path.

【If the target moves, it is highly likely to collide with us. Recommend proceeding at a tilted attitude and increasing descent speed.】Viola reminded.

"I know."

Lin Xian's heart was in his throat. He was well aware of the danger, but the closer they got to the monster, the more intense the dark energy fluctuations became, making everyone feel as if they had fallen into an ice cellar, as if they were in hell. Even the electromagnetic components on the Infinite were interfered with. To maintain stealth, they couldn't activate the shielding device actively. The Infinite could only rely on the Heterogeneous Cube for resistance, while the North Wind 09 wasn't as fortunate. Many inside the submarine already felt a suffocating pressure, with blurred vision, bleeding eardrums, and skin.

At this moment, Lin Xian's ears were filled only with the ticking of his watch and the sound of the sonar detector. He controlled the Infinite to slowly move away from the cliff terrain, then adjusted the bow inclination angle, continuously descending through the turbid sediment.

Before long, the Infinite had moved away from the cliff terrain and entered the area below the abyss. However, according to the terrain scan, they seemed to be crossing some kind of valley gap. But Lin Xian and the others knew that there was no longer any *terrain* here—the massive terrain structure on the scan was actually the body of a living creature, capable of moving at any moment.

In Carriage 5, Shasha and Monica nervously pressed against the porthole, but in their field of vision, aside from the flowing turbid sediment, they could see nothing. Beyond the light inside the carriage, there was no light left in the seawater.

"Are we in between the Oceanic Titan's toes?" Shasha whispered.

Xiao Lou shook his head, not daring to breathe heavily. "I don't know."

After saying this, he looked at Lu Xingchen. At this moment, Fire Bro leaned tensely against his chair, arms crossed, brows tightly furrowed. Noticing Xiao Lou's gaze, he immediately said in a deep voice,

"What are you looking at? I'm not scared. It's just too stuffy in this water. If we were on land, I wouldn't care if it's world-class or not—I'd burn it all away!" 𝘧𝑟𝑒𝑒𝘸𝘦𝘣𝑛𝑜𝘷𝑒𝓁.𝘤𝘰𝓂

Xiao Lou nodded. "I believe that."

Nearby, Ryunosuke was ready to act at any moment. Underwater, very few could use their abilities. In the current situation, he was among those who could help.

As for abilities like Da Luo's, even with ten-thousand-ton strength, they were useless at thousand-meter depths and could only stay in the carriage watching helplessly.

Similarly, in the front carriage, the two sensory ability users, Shiori and A Bai, couldn't stay calm either. Now, perception was meaningless. From their perspective, the dark aura had completely enveloped the Infinite. Shu Qin, Qian Dele, Luo Yang, Xiao Qing, Lü Chang, including Ning Jing and others, could only watch helplessly.

Meanwhile, Monica stood in the rear Twin Star 11R and power carriage, having removed her power armor. She was alone here, her eye abilities operating at their peak. Pressing her headset, she whispered into the frequency to Lin Xian,

"Descend, accelerate by 200 meters."

"Okay." Hearing Monica's voice, Lin Xian didn't doubt it at all. He began letting Viola take over some precision operations, controlling the Infinite to descend deeper.

Hum.

Just after completing the descent, the waters ahead suddenly shook as if the earth were moving and the mountains shaking. Violent underwater currents tore through the water. Lin Xian heard an intense roaring sound and saw on the terrain scanner a hundred-meter cylindrical mountain sweeping past above them.

One of the Oceanic Titan's tentacles!

In that instant, everyone's hearts tightened. Chen Sixuan's nails dug in sharply, her face pale, as if she might lose her breath any moment.

In the cockpit, only Ding Junyi's expression was relatively better, though she was still very tense. Her eyes remained fixed on the instruments.

Outside the silent deep-diving star dust crystal window, the ink-black seawater was too thick to dissolve.

The Infinite continued to descend into the six-thousand-meter trench abyss. Twelve sets of propellers rotated silently at their lowest frequency, the stirred bubbles crushed by the deep-sea pressure the moment they left the blades, not a single sound escaping.

The Oceanic Titan's limbs created various eerie water currents, making the Infinite like a feather encountering turbulence in the air, constantly being pulled. At this moment, they could only rely entirely on KIKI and Ryunosuke's powerful telekinesis to control the Infinite, as well as the North Wind 09 on Laine's side.

"Port side, seven o'clock direction, friction sound."

Monica's voice sounded again.

Lin Xian turned his gaze to the left. In the searchlight's faint beam, a massive wall covered in bluish-gray keratin was slowly settling. In the folds of the Oceanic Titan's torso, mineral vein-like glowing bacterial colonies were embedded, flickering like breathing.

Lin Xian gritted his teeth, controlling the Infinite to hover and stop. After the massive wall passed, he advanced again into the turbid deep water.

The train slid like a leaf pushed by ocean currents, silently entering the mountain's shadow.

"Rising vortex current!"

Scrape!

The next moment, countless bone spines swept through the turbid sediment, scraping past the carriage's pressure hull with a faint metallic screech. The sound instantly made everyone's hearts leap into their throats. If the pressure hull were torn, most people inside would be instantly turned into blood mist by the water pressure.

Only a few minutes had passed, but to Lin Xian, it felt like hours. He had never experienced such a heart-stopping scene. Facing the colossal Oceanic Titan, their abilities and all their means were almost meaningless. The only option was to carefully escape.

At this moment, the two submersibles continuously "threaded the needle" in the abyss, like drifting at the gates of hell, truly terrifying.

Swoosh~

【Current depth, 1790 meters.】

Viola's calm voice sounded.

Over ten minutes later, the Infinite and the North Wind 09 slowly advanced into the deep sea from a vast turbid area. When the Infinite's searchlight finally illuminated the seabed fissure at the base of the cliff, Lin Xian asked Viola in a dry tone,

"Rescan the terrain."

【Sonar detects the offshore island Garland Trench, matching hydrological intelligence. Our current depth is 1790 meters, 4782 meters straight line distance from the cliff. From the scan, we have left the Oceanic Titan's range.】

Beep.

In the dark abyss, the searchlights of the Infinite and the North Wind 09 were like two tiny fireflies in a dark starry sky, minuscule and tranquil.

Upon learning they had successfully descended from the Oceanic Titan's vicinity and escaped the monster's range, the members aboard the Infinite and the North Wind 09 collectively breathed a sigh of relief. A lifetime's worth of cold sweat might have been shed in the past few dozen minutes.

"Heavens, did we escape right under that monster's nose?"

"Incredible."

"Don't celebrate yet." Hearing everyone starting to relax over the communicator, though Lin Xian's anxious heart had eased somewhat, he still didn't dare let his guard down. Instead, he said,

"Everyone, we're only a few hundred meters away from the super vortex array at the bottom of this trench. This isn't a tourist express lane. You all saw what happened earlier. All carriages, prepare and hold on tight!"

Lin Xian's words instantly made hundreds of people tense again. After experiencing the massive turbulence on the cliff, everyone quickly sprang into action.

Super vortex array—every word in this combination sounded unsafe to everyone.

"We've come this far. Being afraid is meaningless now."

Chen Sixuan's complexion had improved considerably. She sighed slowly and said to Lin Xian, "We can only press onward downward in one go."

"It's fine. After surviving great disaster, good fortune follows. We've already passed the most dangerous part." KIKI tapped the sonar detector with her finger. "As long as that monster doesn't suddenly turn around and chase us, I think we don't need to worry."

Lin Xian nodded. Actually, he felt the same. In this sea area, his greatest concern was the Oceanic Titan. Originally, he had thought that if the offshore island explosion achieved a diversion effect, they might luckily avoid the Oceanic Titan without having to confront it directly.

Now that the terrifying monster was right before them and they had slipped away under its nose, he no longer needed to worry about encountering the Oceanic Titan after boarding the Silent Abyss Whirlpool.

Thinking this, Lin Xian didn't hesitate. He directly notified Laine to accelerate, and the two submersibles descended toward the deeper abyss.

The depth gradually reached 2200 meters underwater. The Infinite's beams couldn't illuminate the bottom or the edges in the dark deep water.

"According to the coordinates, we should be approaching the Silent Abyss Whirlpool. Why is there no reaction at all?" KIKI operated the computer, comparing it with Viola's coordinate data.

【Sensors can detect that the current sea area's ocean current speed has reached 8-9 meters per second. Based on thermocline changes and multi-environment comparisons, a large-scale underwater current should exist here.】

Viola's analysis was very calm. 【I recommend deploying small deep-diving drones for multi-directional detection.】

"Detectors? Do we still need to search?" KIKI asked.

"No need."

At this moment, Lin Xian's voice came through. He stood by the porthole, looking out into the deep sea, and said,

"It's right before our eyes."

As soon as he said this, everyone looked toward the portholes. Ding Junyi was very puzzled. Aside from being two thousand meters deep with no light, how could an underwater current be *seen* with the eyes?

But since it was Lin Xian who said it, Ding Junyi immediately dismissed her doubts and went to his side to look out the porthole. However, in the next instant, this unflappable female scientist's pupils contracted, showing an extremely surprised expression.

At the same time, the rear carriages, including Laine, Erica, Azrael, Geddy, and others on the North Wind 09, also looked out in amazement through their portholes.

The searchlights of the Infinite and the North Wind-09 were swallowed by endless darkness, but further away, the pitch-black deep sea began to show faint light. This light grew broader and more vast, like a boundless fluorescent sea.

Outside the portholes unfolded not pitch-black emptiness, but a liquid galaxy composed of trillions of what seemed to be geothermal luminous microorganisms. Azure currents stretched for hundreds of kilometers, as if the entire Milky Way had been crushed and poured into the trench.

The luminous microbial communities were pulled into fine light threads by the currents, visually illuminating the originally invisible underwater super vortex into a massive abyss galaxy, like the eye of the sea. From a distance, one could even directly perceive the terrifying flow speed of the vortex array.

Everyone who saw this scene was speechless, as if beholding a magnificent universe. No one could have imagined seeing such a scene in the deep sea. Those luminous microorganisms allowed them to clearly see a vast super underwater vortex, its vortex path extending into the distance like a giant underwater rainbow bridge!

"At this moment, I don't know whether to say it's too beautiful or too terrifying." Monica stood alone in the nuclear power carriage, looking out the porthole with subtly shimmering eyes. This situation was strange—the massive galactic vortex seemed to carry a deadly beauty, filled with the terrifying power of nature. Combined with the threat of the massive world-class disaster creature behind them, many watched this scene with incredibly complex emotions.

"It's actually a visible deep-sea current." KIKI looked at Lin Xian. "Lin Xian, don't you think this is like a rainbow bridge coming to help us escape?"

Boom!

Violent crustal movement caused the trench bottom to rise with dense bubbles. Mount Garland truly began to rage, the ocean surging. Mantle magma broke through the seabed rock layer like golden-red giant scales, supercritical steam carrying sulfur toxic fog blasted up kilometer-high tsunami walls!

Feeling the water's massive vibrations, Lin Xian immediately ordered without hesitation,

"Viola, charge into the vortex! Everyone, prepare for impact!"
