Doomsday: I Build an Infinite Train.

Chapter 428 Under the Prison (Seeking monthly votes at the end of the month~)

Darkness engulfed the entire city like a tidal wave, with the coastline surging with waves and undercurrents.

The Infinite Train quietly stopped in the maintenance section of the air-raid shelter. The engine was off, all the lights were off, and everyone on board was deliberately keeping their breathing down. Inside the carriages, only the faint red light on the dashboard occasionally flickered, illuminating the tense faces of everyone in each carriage. Even Ding Junyi cooperated by stopping what she was doing, standing still with her hands in her pockets, waiting for the darkness to respond.

This is often the most dangerous time.

Chen Sixuan stood in front of the observation window of the cockpit, staring into the depths of the tunnel through the night vision goggles, where the main track passage was located.

"Something's coming." Monica activated her sonic ability and keenly detected the strange sounds coming from deep within the orbit. Chen Sixuan's eyes narrowed. Her sensory evolution had greatly enhanced her sensitivity to sound. Although not as abnormal as Monica's ability, she could still hear a lot of rustling sounds coming from afar.

"Everyone, prepare to engage the enemy." Chen Sixuan said in a low voice into the communicator, her expression tense.

Rushing sounds came from inside the tunnel, like some kind of multi-legged creature crawling on the rails, occasionally interspersed with low growls, as if its throat was stuffed with rotting flesh. As the sounds increased, the fists of the Infinite crew tightened, and Shu Qin and the others lightly placed their fingers on the triggers, waiting to fire.

Just then, Chen Sixuan and Monica saw several strange figures flash by quickly on the night vision goggles, rushing into the distance with roars, seemingly unaware of the Infinity's existence.

"They're heading towards the decoy!" Footage transmitted by Luo Yang's drone showed a group of red skeletons rushing along the main track. Their bones glowed with an eerie phosphorescence in the darkness, as if driven by some force, frantically rushing into the depths of the city.

"It wasn't just us who released it, but also that huge thing that the Holy City Organization released before. The darkness must have focused its attention on that direction!" Qian Dele analyzed at this moment.

"How strange, these monsters, they're escaping...?" Sasha stared at the screen, her voice extremely low.

“No, it’s not escaping.” Ryunosuke’s psychic power fluctuated slightly as he sensed the energy flow in the distance: “It’s being driven by something.”

A series of slight tremors came from the tunnel, and dust continued to fall. The Infinite, which was hidden in the maintenance section, felt a rumble. Everyone's expression changed slightly when they felt this movement.

"A large creature is coming..."

Chen Sixuan said solemnly, "Everyone, please calm down and act according to the situation!"

Luo Yang was extremely cautious as he piloted the drone. Cold sweat beaded on his face as he carefully withdrew the drone. He said, "It should be the same giant creatures that Captain Lin and Ning Jing saw on the coast and in the sea, as well as those that Ryan and the others mentioned, that were approaching Sea Rock Island. They are at least A-level or Special-level, and there is a good chance that some are S-level."

"S-rank? That's an exaggeration!" Lu Chang said nervously.

Shu Qin remained calm: "Since that giant ocean god has appeared, it's not surprising that there's an S-class or something."

Inside the cockpit, Monica and Chen Sixuan silently stared into the dark passageway. At this moment, Monica spoke to Chen Sixuan and asked...
"If we get caught, do we have any other options?"

Chen Sixuan took a deep breath, looked straight ahead, and said, "If we're discovered, we'll be attacked when it gets dark, so..."

“I mean, if.” Monica’s eyes were sharp.

Chen Sixuan paused for a moment, then calmly replied, "Then kill. We've been through all-night bloodbaths before."

Monica said softly, "It's good to take life and death lightly."

Chen Sixuan looked at her, seemingly sensing something different: "What are you thinking?"

“It’s not that I have any particular thoughts.” Monica crossed her arms and let out a long sigh, a smile playing on her lips. “It’s just that after meeting Lin Xian, he always gives me the illusion that there is still hope even in despair.”

"Isn't this bad?"

“In my opinion, he’s not the kind of leader who can lead a large convoy, but he always gives people a sense of security? No, it’s more like an irrational radiance that makes people lessen or reduce their fear of the dark civilization and the Apocalypse. In fact, objectively speaking, everything we’re facing, including our future survival, seems utterly hopeless.” Monica turned to Chen Sixuan and said calmly, “Isn’t this kind of despair actually more terrifying than the invasion of darkness?”

Chen Sixuan paused for a moment, then said, "Lin Xian and Professor Ye Lan believe that another civilization exists in this disaster, which may be a chance for humanity to survive. Therefore, Lin Xian is trying to use his mechanical abilities and identity as the Swordholder to explore it. I understand his view. The information from the Nantianmen photovoltaic wing surface and the retreat of Xingyuan from Dawn City, as long as the deterrence concept proposed by the Phoenix Society still exists, as long as these anomalies have not been truly proven, and as long as the dark civilization has not destroyed the world before the next dawn, it is all right for Lin Xian and Professor Ye."

She looked at Monica: "This is what Lin is insisting on now. Although it is all speculation and there is no clue whatsoever, it is precisely because he insists on this that he puts himself in this seemingly irrational state."

“Actually, from this perspective, he is very rational.” Monica nodded. “It seems that I don’t know him well enough.”

Chen Sixuan's gaze was indifferent: "Isn't it deep enough...?"

A loud rumble shook the earth, interrupting their conversation. The entire underground tunnel seemed to vibrate violently, with large amounts of sand, gravel, and debris falling from the walls, striking the Infinite with clanging sounds.

At this moment, the night was as black as ink, and along the coastline, the seawater surged, with a huge shadow emerging from the deep sea.

First came the tentacles, thick, black tentacles slapping against the rocks, creating waves tens of meters high. Then came the torso, a mountain-like tumor slowly emerging from the water, its surface covered with writhing holes, from which protruded a rotting human head, its eyes glowing with a ghostly blue light, silently scanning the city.

A giant starfish emerging from the water, a shrunken giant skeleton floating above the water, and a bizarre floating island that drifts in from afar accompanied by a storm...

In the city ruins, split-tailed people, red bones, and even deformed creatures never seen before emerged from sewers, subway entrances, and collapsed buildings, as if summoned by some invisible signal, slowly converging towards the abandoned urban area and the collapsed western rail station. Chaotic howls echoed through the streets and alleys, and residential buildings in the gaps along the coastline were driven and crashed by giant starfish, collapsing. The terrifying black shadows floated above the city, like cosmic ghosts.

"I wonder how things are going with Lin Xian..." Chen Sixuan said with worry as she listened to the alarming noises outside, "Given the situation, they probably won't be able to get close to us tonight."

...Haiyan Island, an isolated island, is as dark as ink, engulfing the entire Haiyan Prison.

The situation was completely beyond Lin Xian's expectations. At this moment, he, KIKI, Ning Jing, and several others retreated to the giant stone tower of the prison to avoid the darkness. They did not rashly enter the underground tunnel. The night wind, carrying the salty smell of the sea and a faint stench of decay, surged in from all directions, creating eddies in the empty area of ​​the prison and making eerie sounds like weeping.

"What is that severed leg? How can it possess such a high level of dark invasion power?"

Ning Jing lowered her voice as she watched Shiori use her powers to heal Ah Bai. Ah Bai's eyes, hidden beneath his armor, had dried up of blood and tears. If he hadn't sounded the alarm at the crucial moment, alerting everyone to retreat, the sudden surge of darkness would have severely injured everyone present.

“Strange, those are a pair of human feet. Although they are broken, they can walk freely. They don’t seem to be a strange creature or a human ghost. They also exude a fierce aura…” Brother Huo said with a solemn expression.

"I wonder if that thing has its eye on us?" Ning Jing asked.

“I can still feel that presence…” Shiori whispered, “It’s right down there.”

shh~
KIKI slowly flew down from the watchtower, made a shushing gesture, and pointed outside: "Some terrifying things have emerged from the sea, they're definitely huge."

Lin Xian operated the drone, zoomed in on the observation screen, and his pupils suddenly contracted.

It seemed that a whirlpool had appeared at sea, and with each wave, he noticed that the coastline was constantly shrinking, indicating that the seawater was beginning to submerge the island.

On the sea, a huge shadow slowly emerged, initially just a blurry outline, then gradually becoming clearer—it was a deformed, bizarre creature, its body like a rotting whale, but with dozens of twisted tentacles, each tentacle ending in a mouth full of sharp teeth. Its skin was covered in pustules, oozing blackish-red mucus, which spread through the seawater as it swam, like some kind of pollution.

“Rank A… no, it’s definitely Rank Special.” KIKI’s voice was tense.

On the distant horizon, more dark shadows emerged from the water, like giant starfish with a gaping maw like an abyss in the center. Some resembled rotting octopuses, but their tentacles were covered with human eyes. There was even a floating "island" with its surface covered with writhing tumors, spewing out pitch-black mist with every breath.

“They are moving towards the main island…” Ning Jing’s voice was cold.

“They must have been lured there by the decoy agent that Holy City used, but we don’t have time to worry about that right now.” At this moment, many corners of the prison were equipped with signal and monitoring devices by Lin Xian’s drones. Hundreds of drones began to search for and take over the entire dark network. At the same time, he began to operate the drones into the underground tunnel to spy on what those severed legs were.

"Lin Xian," KIKI leaned closer and said solemnly, "Could it be a parasitic creature like the one we encountered in the Pseudo-Human Town?"

"I thought about that too, but it's too weird. Luckily, we didn't go down directly," Lin Xian said.

Ning Jing stood by the tower window, observing the situation outside with Xiao Qing, keeping watch for the team. Inside the tower, only the signal light of Lin Xian's drone was flashing; otherwise, everything was shrouded in darkness.

Lin Xian then shifted his gaze to the drone, piloting a Reconnaissance drone back into the underground warehouse. Under the night vision, the pit resembled a black abyss. As Lin Xian looked at the terrain, images from Gu Zheng's consciousness flashed through his eyes, capturing the scene of many members of the Holy City Organization emerging from the tunnel. He was immediately puzzled, wondering how these people were coming out of here.

He immediately had the drone deploy a small signal device next to the pit, and then it slowly descended into the pit. The drone was silent. Lin Xian held his breath as he looked at the dark outline of the pit. In the noisy night vision image, a deep, large drainage pipe appeared that seemed to have no end.

Woo~
A faint flight control sound came, and the drone slowly turned. On the other side was also a dark tunnel. As the drone descended, Lin Xian did not find any other abnormalities. However, before dark, they did see a pair of severed feet walking strangely in the tunnel. If Ah Bai hadn't warned them quickly, they didn't know what they would have encountered. On the severed feet, Lin Xian seemed to sense a kind of forbidden fluctuation. Thinking of this, he immediately activated a search module on the Scout.

That was a special device used to detect forbidden objects that Lin Xian seized from the member of the Holy Revelation called "Old Ghost" in Silent City. Later, Lin Xian modified it and put it on this drone, which is used specifically for searching for forbidden objects.

At this moment, strange noise appeared on the scout's screen in Lin Xian's observation window, accompanied by signal lag and flickering. Lin Xian immediately sensed something was wrong. The screen in front was still completely black and empty. He frowned and began to rotate the drone's view again. Perhaps affected by the abnormal signal, the drone rotated amidst the lag, and the fragmented screen began to switch to the rear. At this moment, a black shadow appeared in the screen without warning!
It was a massive creature, resembling a long, intertwined black worm, almost filling the entire pit. It appeared eerily in the drone's view. Lin Xian's eyes narrowed sharply as he looked down and was shocked to see that the severed human feet had reappeared on the ground ahead, completely torn apart from the knees. The dense black worms were growing from the pale, rotting tissue of those severed feet, covering the entire pit!

Lin Xian immediately frowned and couldn't help but gasp. He realized that what they had seen earlier was not just a pair of severed legs, but a giant tunnel creature. Strangely, apart from the pair of human severed legs, the main body of this thing was invisible!

Thank goodness! If Ah Bai hadn't noticed, none of the people on Lin Xian's side would have been detected, even with the power armor observation system and radar system. If they had gone down rashly, they wouldn't have even known what bit them when they were bitten. It was terrifying!
Wow~
At this moment, the swarm of creatures entwined with countless black worms in the tunnel surged toward the drone, seemingly devouring it. In the currently lagging footage, Lin Xian could only see countless long snakes crawling past the camera. The next moment, an even more horrifying scene appeared: among the black worms, a large number of undigested human corpses began to emerge. Some were skeletal, some had severed limbs, and several of them were still wearing the power armor of the Holy City Organization, indicating that they had not been dead for long.

Just then, the video abruptly stopped, and Lin Xian didn't know whether the drone was damaged or the signal was completely lost.

"How is it?" KIKI asked.

“That tunnel should lead somewhere. People from the Holy City Organization have appeared here, but there’s an invisible monster blocking the flood discharge pipe,” Lin Xian replied.

"An invisible monster?" KIKI frowned. "How big is it?"

Lin Xian shook his head: "We can't see the whole picture, but that concentration of darkness intrusion is definitely not simple."

At this moment, Lin Xian thought of something and said to KIKI, "KIKI, use the information you got from the Federation before to check this prison. If this kind of passage is related to the military, then we should know what the Holy City Organization is doing down there."

“That’s right!” KIKI immediately operated the power armor’s intelligent computer. The data in her information center had already been imported into it. Soon, she retrieved information related to the island’s sea rock prison and then searched for a while.

Not long after, KIKI's surprised voice came from a screen of light.

"How about it?"

"Lin Xian, you guessed right." KIKI simultaneously activated a holographic screen, magnifying a secret blueprint. Ning Jing and Huo Ge, who were standing nearby, both missed it. Ning Jing couldn't help but exclaim in surprise upon seeing it.
"G085 - Nuclear Submarine's Underwater Secret Port!?"
