Doomsday: I Build an Infinite Train.

Chapter 448 Deep Dive Project
Ghost waves crashed over Haiyan Island, and storms raged in the sky. At 16:12 in the afternoon, the atmosphere in the monitoring hall below the submarine base on the island was deathly silent and heavy.

Everyone remained silent. The people on the Infinite quickly calmed down from their surprise. They had all encountered many life-or-death situations, and they were used to Lin Xian's crazy plan. Moreover, it seemed to be the only evacuation option under the current crisis.

Meanwhile, the Falcon Fleet members all wore solemn expressions. Gaddy broke the silence by speaking up: "So, Captain Lin, your plan is for us all to board that nuclear submarine and escape through that 'Silent Abyss Vortex'?"

Lin Xian responded, "The orbit, the sea, and the sky all seem to be unworkable at the moment. Apart from taking refuge on the island, there is no way to escape so many strange entities 'feasting' here. However, with the instability of the Garan volcano, the geothermal well has also become a time bomb that could explode at any time. Hiding is no longer the best option. You should all understand this."

Ryan nodded and said quite seriously, "Did you come up with this plan because the energy outlet on Chasan Island captured images of the giant ocean god, so now that we're passing through the Ridge Abyss, it's an opportunity?"

"Yes."

“OK.” Ryan immediately pulled down his sunglasses and said decisively, “I agree to this plan.”

"Ryan!"

Erica quickly spoke up, "Even if we abandon the fleet and the Neptune, that submarine can't carry that many people. Should we abandon all the weapons and supplies as well?"

“That’s right.” Vanessa pulled up some data: “I just checked. The Abyss-class Borei-09 strategic nuclear submarine below has a capacity of 400 people. We have nearly 500 people here, plus heavy powered armor. If everyone goes up, it will be a huge burden. Even if we manage to escape successfully, how long can so many of us survive in the Pacific Ocean without supplies?”

“There’s another problem,” the mechanic Azir said to Ryan. “As I just mentioned, this super vortex has a flow speed of over 40 centimeters per second and a depth of over 1000 meters. This is a huge test for the submarine’s structural materials. Although the people of the Holy City have already traversed this path, the Garan volcano is still erupting. Water temperature and volcanic sand are both issues. Under these circumstances, if the submarine were to collide with a large volcanic rock or a powerful vortex, it could be directly shattered by the water pressure and vortex, let alone the strange creature.”

Hearing what everyone was saying, Ryan simply raised his hand to signal everyone to be quiet, then shrugged and said...

“Of course I understand these circumstances, but besides the plan Lin mentioned, does anyone have a better idea?” He glanced at the time. “It’s 16:20 PM now. We’re hiding here and don’t even know whether darkness or a volcanic eruption will come first. To survive, we need to take a huge gamble, don’t we?”

The core members of the Falcon Fleet all fell silent. Ryan then looked at Lin Xian and said, "Lin, I have the best submarine mechanics team here, with rich experience. Perhaps the success rate can be improved?"

"It should be possible," Lin Xian replied.

"Lin Xian." At this moment, Chen Sixuan also spoke up: "If we all evacuate by submarine, what about the Infinity?"

Lin Xian looked at Chen Sixuan: "I didn't say we would all evacuate by submarine..."

"Huh?" Chen Sixuan frowned slightly upon hearing this: "Then we..."

“We’ll take the train to the sea!” Lin Xian said directly.

These words shocked not only the Falcon Fleet but also the Infinite Fleet.

"What?! You're going to drive a train into the deep sea?!" Vanessa's eyes widened in disbelief.

"This is practically suicide!" Erica exclaimed in surprise. "A train, how could this be..."

Meanwhile, although the crew of the Infinite knew that the Infinite had undergone deep-sea modifications, they did not expect that Lin Xian would directly drive this heavy train into the deep sea for such an ultra-deep-sea escape.

“I thought you were planning to use the Sky Train.” Monica crossed her arms, even she was a little puzzled.

Lin Xian shook his head and said with a wry smile, "I'd like to, but given the current situation, it's probably not feasible."

"Why?!" Sasha exclaimed in surprise, "Even if we have a large spaceship, we can't use it?"

"You're so silly." KIKI floated to Lin Xian's side and said to Sasha, "You said it yourself, it's a big spaceship, guess why it can't be used?"

Upon hearing this, Shu Qin and the others immediately looked up and observed their surroundings. Qian Dele, realizing what was happening, said helplessly.
"The deep-water port space and underwater passage are too narrow for the Sky Train to pass through?"

Lin Xian nodded, looked up at the sky, and said, "Yes, unless we're outside, but that's impossible now."

The underwater passageway of the deep-water port was specially built by the original military base for submarines. The giant airship like the Sky Dome cannot pass through it at all. Lin Xian even had a hard time taking this behemoth out of the Black Star Forge in the deep-water port, let alone getting on it. If we had to find another way, it would be for everyone to enter the deep water first through their power armor, and then land after Lin Xian took the Sky Dome train out of the water. However, this plan is too stupid. In comparison, it is much more direct to use the modified Infinite.

In addition, there is another reason: the Sky-class arsenal ship has not yet been completed. This unfinished starship is not as reliable as the Infinity.

Watching Lin Xian seriously discuss the plan to launch the train into the water, the members of the Falcon Sea Group looked at each other in bewilderment.

"Are you really going to drive the train into the deep ocean?" Ryan asked.

"Isn't our train amazing?" KIKI replied confidently. "Don't underestimate it. This train can not only go to sea but also soar into the sky. It can even go toe-to-toe with S-class trains. You don't need to worry."

"That's right!"

Lu Xingchen stood up at this moment, and said with a heroic expression: "If you want to turn a desperate situation into a life-or-death one, you must have the courage to put yourself in a life-or-death situation. We have extraordinary divine power, so what do we have to fear if we go to the sky or into the sea!"

Seeing the guy who had just been dozing off looking so smug, Sasha immediately leaned over and covered his mouth to remind him.
"Brother Lin's plan is to have you sit in the Infinity and then sink to a depth of a thousand meters in the ocean, drill into a super underwater vortex from the territory of the underwater volcano and the ocean god, and then escape..."

Upon hearing this, Lu Xingchen's lower body went limp, and he almost lost his balance. Seeing Xiao Qing's gaze upon him, he quickly regained his composure and said loudly...

"No...it's alright, it's just a mere underwater whirlpool."

“Alright.” Seeing that everyone on Lin Xian’s side looked calm, Ryan clicked his tongue in amazement and looked at Lin Xian, saying, “Lin, when shall we make our move?”

"immediately!"

Lin Xian immediately said decisively, "Ryan, you guys arrange for people to board the ship right away. Move as much of the supplies as possible. We should set off before dark."

"Okay." Rumble!
Before the words were finished, another violent earthquake struck, but this time it did not resemble a volcanic eruption. Instead, it was more like the violent tremors caused by some giant beast stepping onto the continental shelf of a rocky island, with a deafening roar!

"That monster has set sail!" Ning Jing's expression hardened. "We need to hurry."

"Wait, there's another problem!"

Gaddy looked at Lin Xian and Ryan with a tense expression and said, "We've descended such a long distance from here to that super vortex. Once we're tagged by the monster, it might be difficult for us to escape. Are we just going to bite the bullet and run?"

“You’re right, so I plan to use a decoy,” Lin Xian said immediately.

"A decoy?" Gaddy retorted. "How could a decoy possibly cover such a wide area?"

“I’m not talking about ordinary decoys.” Lin Xian’s eyes sharpened, and he tapped KIKI’s mobile terminal. Immediately, the holographic screen changed, and a giant mechanical device appeared. It was a three-dimensional image of the Deep-3 core heat extraction device in the geothermal well in the submarine base. He immediately said, “Since we’re going to run away, let’s set off a grand fireworks display to help us make a run for it.”

After saying that, he said to Viola, "Viola, if I actively detonate the Deep-3 core thermal detonation device to release the thermonuclear energy in the geothermal well, how much of a chance of success can that give us?"

"What?!" Everyone was shocked to hear Lin Xian's words. He was planning to deliberately detonate the volcano?!
[If this operation is carried out without the appearance of the Dark Mark, the success rate of the plan can reach 23.4%, but there are also greater risks, including but not limited to 1. attracting more strange entities and even Unija 1 to the waters near the island; 2. triggering a volcanic chain reaction, causing the volcano to erupt; 3. ...]

"Alright," Lin Xian interrupted.
After saying that, he immediately said to everyone, "23.4%, which is rounded up to 100%. In order to turn this into a lifeline, everyone should act quickly."

Ryan and the others: "..."

Upon hearing Lin Xian's words, the members of the Falcon Sea Group felt a sudden jolt; the calculation that 23% rounded to 100% was simply astonishing.

However, no one had time to pay attention to these details. Under Ryan's arrangement, the Falcon Fleet immediately began to board the ship and move supplies. At the same time, due to space issues, Ryan consulted Lin Xian and asked Vanessa to lead dozens of people to prepare to board Lin Xian's 'train' that was about to be launched.

Lin Xian immediately began two preparations: one was to prepare for the detonation of the Deep-3 core thermal detonation device, and the other was to release the Mugen-go deep-sea submersible system, and then have KIKI and Ryunosuke transport the train from the platform to the deep-water port.

16:35
Haiyan Island trembled violently during the ongoing earthquakes, and the lighting equipment on the ceiling of the monitoring hall flickered.

In the waters southeast of Chasan Island, the thick smoke from the Garan volcano has turned the sky iron gray, and in the distance, an indescribable, enormous black shadow lurks on the sea surface, with unnatural, eerie lights flashing intermittently among the waves.

At the deep-water port, Ryan led his men, shouting orders. The Falcon Squad members began boarding the submarine in a flurry of activity. Many of them were entering a submarine for the first time, and a tense atmosphere permeated the air.

"Mechanical team, check the pressure valves! Power team, start the engine within three minutes!" Mechanic Azir's roar echoed in the steel-framed corridor. At the nuclear submarine's hatch, Erica and Gedi led the ordinary survivors of the Falcon Squad into the inner living quarters. At this moment, with the continuous earthquake, the surface of the deep-water harbor began to churn with boiling bubbles, and the smell of sulfur mixed with the sea odor assaulted their nostrils.

Seeing this, Ryan frowned, checked the time, and quickly spoke into the communicator.
"The eruption has been ongoing, but we don't know when it will erupt on a major scale, at which point hundreds of miles of sea will be a hell."

"This world is hell."

In the upper supply depot, Lin Xian watched as Viola directed the construction and maintenance robots to begin deploying the deep-sea module that Silent City had previously built for the Infinite.

"The fluid balance module under the vehicle should be checked again." Luo Yang nervously approached, holding a mobile terminal. "We fought several battles in Haiyan City, so we need to consider whether it was damaged."

"Very thoughtful." Lin Xian nodded, instructing Viola to proceed simultaneously.

Amidst the hum of the robotic arm, the train chassis deployed three layers of fin-shaped deflectors, and Luo Yang's detection drone's projection flickered and jumped on the rails: "Pressure hull charging 87% 92%!"

On the bus, the moment Chen Sixuan pressed down the pressure-resistant window, another earthquake shook the ground, and concrete from the platform above fell onto the bus roof with a crackling sound like popping beans.

"Deep-sea airtightness test of the train completed!"

"Train watertight compartment pressurization test!"

Lin Xian arrived at the Infinite cockpit, and the Mechanical Heart activated, quickly checking all the carriages.

He noticed the fine beads of sweat on Chen Sixuan's forehead and immediately asked softly, "Are you nervous?"

"It's impossible not to be nervous." Chen Sixuan took a deep breath and looked straight ahead. "Although I believe in you and in the Silent City Dao technology, however..."

"But I still find it a bit unbelievable to launch this train into the water?" Lin Xian said.
Chen Sixuan nodded: "Going up and down mountains, it's really not easy." She turned to look at Lin Xian, her expression slightly nervous.
"Did I not tell you that I have thalassophobia?"

Lin Xian was slightly taken aback: "I really didn't say that."

Chen Sixuan raised her palm to show Lin Xian, and breathed a sigh of relief, saying, "Thousands of meters deep in the ocean, where you can't see the sunlight, unknown deep-sea monsters, underwater volcanoes, super whirlpools—just hearing about these makes my palms sweat. Okay... don't laugh at me."

"How could I laugh at you?" Lin Xian smiled helplessly and said frankly, "Teacher Chen, actually... I'm scared too."

Compared to going to heaven, Lin Xian was actually more afraid of going into the sea. The reason was the same as what Chen Sixuan said: the unknown in the deep sea, the suffocating feeling of sinking, it was impossible not to be nervous. Although he calmly discussed the success rate of the plan with Viola, Lin Xian had a deep-seated fear of the deep sea, a feeling similar to drifting into the depths of the universe in the uninhabited space.

But Lin Xian had no other choice. If he had the chance to fly over the sea, he would never choose such a risk. However, combined with Gu Zheng's consciousness information, Lin Xian knew that this path must be feasible, provided that their luck was not too bad and that the train could withstand the high-pressure ocean currents.

The propulsion system has been deployed and is ready for water entry testing.

Just then, Viola's voice came through.

Lin Xian immediately turned around and said in a stern voice, "KIKI, prepare to launch the Infinity!"
