Doomsday: I Build an Infinite Train.

Chapter 401 The Swordholder!
Bang, bang, bang.

The Infinite's iron wheel passed the old-style transport tracks of Yongcheng Port and began to merge into the main orbit of the planet. The adaptive magnetic levitation device was activated, the sound of the iron wheel and the track disappeared, and it quietly began to accelerate.

Lin Xian had forgotten the last time the sun shone so brightly. The train passed through a desolate plain, its heavy armored body coated with a thin layer of gold. The sky reflected in the train windows was almost transparently blue, with occasional cloud shadows drifting by like silent ghosts.

Inside the carriage, melodious music played over the loudspeaker. Dust particles floated and slowly rotated in the beams of light. In carriage number 2, Sasha was asleep by the window, her eyelashes casting tiny shadows on her cheeks. KIKI, dressed in a refreshing shorts and sweatshirt, was leisurely watching a variety show before Apocalypse Day on her swivel chair, spinning a few colorful lollipops with her telekinesis, a bright smile on her face.

The research carriage has been completely transformed into a forest of plants, crisp and dark green, and stepping inside feels cool and serene. Miao Lu and Xiao Yuan, under the guidance of Director Ding, carefully record the growth of various plants under the abundant sunlight. Viola has replaced Grace's work and become the AI ​​butler on the New Infinity.

Apart from the power car group, all other cars have been replaced by the higher-specification Queen Mo automated cars by Lin Xian. In addition, some of the weaponry from Silent City and Project Emperor has been incorporated. Now, apart from one Eternal-class 'Tianxing 5C' nuclear-powered car and the Dragon-class traction car that Lin Xian has retained, all other cars on the train have been readjusted.

Besides the building and Brother Huo, two other people have moved into carriage number 5. One is Brother Huo's apprentice, Sun Yuzhen's son, Mo Xiaotian, and the other is Long Zhijie, an inorganic matter power user from Silent City who has broken through to the angel level.

This wasn't Lin Xian's arrangement, but rather a special request from Shinji Mochizuki under the Phoenix Society's "Spark Project." After the Battle of Dawn City, Silent City suffered severe damage. Now that the three major Star Abysses are stable, Shinji Mochizuki, combining the Emperor Project and the Crimson World's bio-engineering technology with the dark energy data from Dawn City, initiated the reconstruction of Silent City at Yongcheng Port. He also supported and participated in Dawn City's repair project. And when this guy heard that Lin Xian planned to travel from the Pacific Ocean across the Republic of Sanctuary Islands and then into Ushuaia in South America, he actually arranged for Ryunosuke and Shiori, the two Silent City members with the greatest potential for supernatural abilities, to be included in Lin Xian's ocean orbit journey.

The goal was simple: to participate in the 'protection' of Lin Xian, while Shinji Mochizuki hoped to help the two of them grow their abilities further and become a great asset in the future.

Lin Xian knew what this guy was thinking, but he had his own plans for taking the ocean track this time and couldn't bring too many people. For safety reasons, the Infinite Alliance joined the Phoenix Society's Dawn Center, with Jian Xuwei, Jiang Yun, and Shi Diyuan leading the Silver Star, the joint train, and a huge convoy to the Qionggu Strait. Lin Xian, on the other hand, joined Ye Lan's 'Spark Project'!
Project Spark is a proactive defense plan announced by Ye Lan, the commander of the Phoenix Society, after announcing the start of the Deterrence Era and responding to the unknown slowdown state of 13 Star Abysses around the world.

Following the defense of Dawn City, the Dark Crisis underwent a significant transformation. After shrinking back to its original size, Star Abyss 5, 7, and 8 unexpectedly entered a phase of slow expansion, which was better than the Phoenix Society had anticipated. By combining the information from Lin Xian, Chu Yan, the Corpse Drivers, and Operation Crescent Moon, Phoenix Society Commander Ye Lan believed that after humanity mastered the conversion of dark energy and recaptured the space defense platform to counterattack the Corpse Drivers of Star Abyss 5, this unpredictable latent threat likely led to a change in the Dark Civilization's strategic intentions towards human civilization, possibly characterized by caution or other shifts.

Simply put, humans who remain silent in the dark while also shielding themselves from the darkness's invasion have become a threatening entity with both drug resistance and capability. This gives humans, who were originally like ants, the possibility of confrontation or proactively choosing survival strategies when civilization's information returns to darkness and opacity.

Thus, Project Spark was born, with two objectives. First, to use the advantages of dark energy shielding to reverse humanity's disadvantage in the dark, and then to conduct a comprehensive and in-depth investigation of all star abysses, and to try to use this technology to make one of humanity's great weapons, nuclear weapons, play a role again, and to seek the possibility of establishing military deterrence. Second, to use S-class bio-armor technology to try to break through the celestial curtain for the second time, with the aim of opening up the polar Kunlun central hub and investigating the possibility of restarting the Moon Gazing Planetary Ring.

The successful counterattack in Dawn City and the establishment of Project Spark greatly boosted the confidence of the remaining human survivors around the world. Most importantly, everyone knew that humanity could survive the invasion of darkness, that the infection could be contained, and that they could regain control of water resources.

In carriage number 5, Lin was testing a new suit of armor he had made on the building, while Huo Ge, Ryunosuke, and Mo Xiaotian sat to the side, drinking iced tea and curiously watching the nearly two-meter-tall building in its berserk mecha.

Woo~
Under Lin Xian's mechanical abilities, the mechanical units throughout the building began to automatically bolt together. In addition to their combat functions, the two specially designed Qilin mechanical arms were also equipped with underwater and deep-space thrusters and had a complete life support system, making them an absolute weapon of mass destruction.

"Yes, Not Bad."

Lin Xian looked at his masterpiece with a hint of satisfaction in his eyes.

"Give it a try, Building."

The building looked at the two mechanical arms with great curiosity. It accidentally triggered something, and the mechanical gates on the arms opened, releasing several small destruction missiles that were aimed at Brother Huo and the others who were drinking tea nearby.

"Hey, hey, hey... Building Bro!"

"Brother Lou, wait a minute!"

Huo Ge and Mo Xiaotian almost choked on their iced tea and immediately assumed defensive stances.

The building was thrown into chaos, but in the tension, the propulsion system was suddenly activated, and the cooling fins on the legs began to heat up.

"Brother Xian!"

The building panicked.

Lin Xian, standing to the side, snapped his fingers and immediately shut down the building's armor's weapon system.

"Brother Xian... I've never used power armor before. Is this not suitable for me, considering my superpowers..." Lou said somewhat awkwardly.

To everyone's surprise, Lin Xian shook his head and said in a serious tone.

“It suits you perfectly. I’ve been wanting to prepare a set for you for a while now. Your superpower is blood energy, but you can’t always fight monsters hand-to-hand. Besides, once we enter the Pacific Ocean, we’ll need mobility both underwater and in the air. You can’t exactly swim in the Pacific Ocean with a steel-slaying greatsword, can you?”

“Brother Lin is right.” Lu Xingchen nodded in agreement and said, “Even if I can fly through the air with fire, I still need the assistance of a power armor. This Black Dragon Armor was specially made for you by Brother Lin. I believe you can make full use of it, Brother Lou.”

"Yes, yes, he looks really cool!" Mo Xiaotian said, his eyes lighting up.

Lin Xian pointed to Ryunosuke, who was silently drinking tea and said with a smile, "Look at this guy, an all-around ability user. He's also wearing a power armor that enhances his combat power, mobility, and defense. It's better to be prepared."

"Okay, Brother Xian, I'll take a look."

Lou was overjoyed to hear Lin Xian's words. As soon as he turned around, the black dragon armor produced a hydraulic sound. It looked heavy, but it actually had a powerful energy core that could help Lou generate greater explosive force.

Carriage 6 now serves as the train's storage and dining car, densely packed with various supplies. In the middle of the carriage is a specially designed sunken aisle sofa that can accommodate more than twenty people in the carriage to eat and rest together, or it can be used for meetings.

Meanwhile, the dining car was bustling with activity. Chen Sixuan, Ning Jing, Shu Qin, and Sun Yuzhen were setting up and taking inventory of supplies. On the sofa, Qian Dele, Luo Yang, and Lü Chang were playing cards. Not far away, A Bai and Xiao Qing sat silently. Monica, holding a glass of red wine, sat at the farthest point with her legs crossed. When she saw Lin Xian come in, she smiled slightly at him and then continued to look at the sunshine and scenery outside the car.

It can be said that the core members of the Infinite Alliance are basically all here. Liang Lei and Li Yi, who are responsible for production, as well as Lao Mo, who is not good at combat, and a group of children, all follow the Infinite Alliance land forces on a safer route.

"Team Lin."

Seeing Lin Xian enter, Ning Jing spoke first, walking over and asking, "Are we entering ocean orbit tomorrow?"

Lin Xian nodded: "The weather is nice today, let's go to the coastline and rest for the night."

“Indeed, the weather is really nice.” Qian Dele leaned back, wearing sunglasses, looking relaxed. “Compared to fighting or anything like that, traveling by train is much more comfortable.”

"This isn't a trip," Luo Yang said seriously. "We're going to cross the Pacific Ocean, meet up with the floating city of Noah, and head to the Republic Islands. Who knows what trouble we might encounter in the sea?"

“And we have to cross the 13th Star Abyss.” Ning Jing turned back and smiled at Qian Dele: “This time it won’t be so easy to take a detour.”

"It doesn't matter."

Qian Dele remained unfazed upon hearing this: "Whether it's a giant sea monster or a zombie horde outside, as long as I see it as scenery in my heart, that's travel."

“You’re quite optimistic,” Chen Sixuan said with a smile. “The ocean section of the circumpolar orbit will be along the mid-ocean ridge. In other words, we’ll be advancing along the edge of the deepest trench in the Pacific Ocean. Didn’t you say before that you had thalassophobia?”

Upon hearing this, Qian Dele's smile vanished abruptly. He adjusted his sunglasses, looked at Chen Sixuan, and then at Lin Xian: "Now that you mention it, she doesn't seem so beautiful anymore."

"It's not too late to change your mind now," Lin Xian said as he walked over.

"Forget it." Qian Dele looked at Lin Xian, put his sunglasses back on, and said leisurely, "I'll still follow you. Monica is right. There's always a way to survive if I follow you. You turned the tide of the battle in Dawn City, which was in such a desperate situation. I should also contribute to saving the world."

Lin Xian smiled, then gestured to Monica.
"Thank you for the car, Queen Mo. This Infinity is in its prime now. Apart from not being able to fly, it's fully functional."

Monica smiled slightly and said elegantly to him, "You're welcome. I'm still waiting to ride on your Sky Starship."

"soon."

After Lin Xian finished speaking, he turned and walked towards carriage number 1. Behind carriage number 6 were the living quarters for these core members. Except for Monica, who still lived alone in the luxurious carriage number 9, Qian Dele, Luo Yang, Lü Chang, A Bai, and others lived in carriage number 8. Shu Qin, Xiao Qing, Miao Lu, Ning Jing, and Shi Zhi lived in carriage number 7. The last carriage, number 10, was a special power carriage that Lin Xian had prepared for emergencies—the Giant Whale 03E heavy-duty gas turbine locomotive.

Lin Xian also brought along this Power Warrior, which had accompanied him all the way, hoping it might come in handy at some crucial moments.

Moving forward from the rear carriage, Lin Xian arrived at carriage number 4. Upon entering, he was greeted by a vast expanse of greenery, including various trees, vegetables, and fruits. With the transparent sunroof open, the entire carriage felt like a forest, a truly refreshing sight.

"Team Leader Lin!"

Xiao Yuan, who was picking fruits and melons with Miao Lu, saw Lin Xian approaching and quickly stood up, greeting him happily.

"Wow, there are tomatoes and cucumbers today." Lin Xian's eyes lit up. He couldn't resist taking a cucumber from the small round basket, wiping it on his clothes, and taking a bite. Immediately, a sweet and juicy flavor burst in his mouth.

"The sun has been shining brightly these past few days, and they're growing very fast." Xiao Yuan smiled gently. "I heard that people need to supplement their vitamin intake when they're at sea for too long, so Director Ding switched to planting a lot of melons and fruits."

"That's right, Director Ding's superpower makes plants grow incredibly fast now." Miao Lu nodded hurriedly in agreement, "These cucumbers were only planted yesterday, and they're already bearing fruit today!"

"Increased production volume is practically a god-level superpower."

Lin Xian took a bite of cucumber: "This isn't in the official records of the Phoenix Society, the only one is in our car."

"The only mechanical superpower is also in our car," Miao Lu said with a grin.

Lin Xian smiled and then walked forward. Xiao Yuan followed from behind, and Miao Lu jokingly pulled her back: "Stop looking, your eyes are practically glued to the ground."

Xiao Yuan blushed and said to Miao Lu, "I'm just so happy that Team Leader Lin actually brought me along on this trip."

Miao Lu exclaimed in surprise, "What's so surprising about that? If you and Director Ding hadn't used the Silver Dragon 100,000 to save Captain Lin at the crucial moment, he would be dead by now. You're so capable, Captain Lin would definitely want to take you with him."

Xiao Yuan frowned slightly and said calmly, "That was Director Ding's plan. I was just helping out."

"Hehe, do you hope that Captain Lin actually has feelings for you and that's why he brought you along?" Miao Lu smiled with narrowed eyes.

"Not at all!"

……

Car No. 3.

"To summarize the growth data, I need to create a file to verify the growth curves of different vegetables, light, and cold-dark reagents on all the superhumans in the vehicle at specific times..."

[Key factors that may be affected include, but are not limited to, the individual's own background, growth potential, gender, age, and individual conversion rate. This may require more than 3615 comparative experiments to obtain the experimental data you need for conclusion verification.]

“I know that we should first assess the major items and then screen the details to find the greatest common denominator as a reference for Lin Xian.”

Lin Xian arrived at carriage number 3 and saw Ding Junyi conducting research with Viola while keeping her head down.
"Lin Xian." Hearing footsteps, Ding Junyi greeted him without even looking up.

"I heard your superpowers have improved a lot?" Lin Xian said as he walked over.

Ding Junyi took a moment to raise her hand and pointed. In an instant, a ripple appeared, and the several potted plants on the table suddenly began to grow explosively, spreading branches and leaves as if they were alive. Then they all converged on Lin Xian, as if tentacles completely surrounded him, forming a simple 'cage' in a short time.

Lin Xian looked at the swaying green plants around him with surprise: "How come they're like living things?"

“Strictly speaking, plants are living things.” Ding Junyi looked up at Lin Xian. “However, I know you don’t like this answer, so the actual situation is that I caused the plant’s growth fibers to multiply and divide rapidly. In this accelerated process, it became ‘moving’. You can think of it as me speeding up the growth process, but it looks like it’s moving.”

Lin Xian nodded: "So it's one-way? I thought you could control plants like you control tentacles."

"It can't be that flexible; plant fibers and muscle fibers are not essentially the same thing."

Seeing Ding Junyi's serious expression, Lin Xian smiled and asked, "I'm curious, how did you come to believe that the Silver Dragon Ten Thousand Mistakes could save me?"

“I don’t think so.” Ding Junyi put down her work and looked at Lin Xian calmly, saying, “I don’t know how long the Silver Dragon Ten Thousand Mistakes can help you hold off the corpse driver, a second or a moment, but for me, this is the only thing I can do for you.”

Lin Xian's expression was complicated. He wanted to say something but then became speechless. After thinking for a long time, he only managed to utter one sentence.

"Thank you."

"You're welcome."

At that moment, Lin Xian was unaware that Chen Sixuan had located him from several kilometers away the instant the South Heavenly Gate opened fire, and that Ding Junyi and Xiao Yuan had already arrived with the Silver Dragon Ten Thousand Mistakes. He also didn't know that Qian Dele and KIKI were rushing over at the same time to rescue him. Just at this critical moment, the dimensional bubble opened up, and Qian Dele used his speed force to take Lin Xian away with him. This allowed Lin Xian to survive even when facing the destructive beam of the South Heavenly Gate, something Lin Xian had never expected.

All I can say is that my teammates were amazing.

At this moment, Lin Xian arrived at the new Eternal-class cockpit of the Infinite. Looking at the sunlit fields in front of him, he took a deep breath. Then he sat in the driver's seat, and a voice came to his ear.

"Although Star Abyss No. 13 is the only one located in the ocean, it is also the largest in scale. It forms a super-large storm zone with a range of more than 10,000 kilometers at the junction of the western Pacific Ocean and the Black Ocean. Even trying to pass through that area via a circumpolar orbit would be an extremely dangerous thing."

"It's dangerous for either of us to go anywhere."

Lin Xian looked at Chu Yan: "The corpse driver's spiritual power probed the two of us, so I told Professor Ye that the darkness might be watching us."

“I understand that,” Chu Yan said, looking at him. “I’m just curious, now that you’re the ‘Sword Bearer’ of the Southern Heavenly Gate, why would Professor Ye let you cross the Pacific Ocean in an elite squad?”

Lin Xian looked at Chu Yan's semi-transparent consciousness beside him and said, "So I have already told Professor Ye that we two must split up. You are currently on your way to the Dawn Center. The Phoenix Society will ensure your safety."

Chu Yan frowned slightly: "I didn't know I could contact Grace."

"You'll know when you wake up." Lin Xian smiled. "You should have some free time lately. I've spoken with Professor Ye, and you can assist in establishing a connection with the South Heavenly Gate. However, we probably won't be able to get the shielding layer of the Heavenly Curtain in a short time. For safety reasons, the two of us 'Swordholders' must separate. You can take the land route to maximize your safety, while I can take the ocean orbit to reach the Kunlun Central Hub in the polar region the fastest. These are two different arrangements."

"So you dismantled your entire Infinite Alliance and took a group of elites on an ocean-going route just to reach the polar regions faster?" Chu Yan asked.

"Isn't that reason enough?" Lin Xian asked with a smile. "If I reach the polar regions faster, I can enjoy the Phoenix Society's resources in peace and improve my abilities. Besides, I'm tired. It's a good thing that I don't have to worry about the survival of tens of thousands of people, isn't it?"

"Lin Xian."

Chu Yan smiled and looked at him: "Have you forgotten that I've seen through all your thoughts? Your mechanical ability is completely different from all other ability users. Although you like to say that you are an egoist, in reality, you are bound by responsibility. So do you think I would believe that you are only doing this for this purpose?"

Lin Xian was taken aback upon hearing this, then smiled helplessly.

"Okay, I really don't have any secrets from you."

"Do you remember what we saw from the corpse-driver?" Lin Xian said calmly, "There are humans beneath Star Abyss No. 13."

Chu Yan nodded: "Yes, this is beyond reason. Deep in the ocean, beneath the star abyss, there are actually humans..."

"Do you remember that after you invaded Julius's consciousness, you obtained a lot of information related to the SIID Foundation?"

"remember."

Lin Xian looked at the approaching coastline in the distance and said, "We previously thought that the SIID Foundation was just a conglomerate or organizer behind the Crimson World, but now, after reviewing that information, we have found that many of my previous conjectures have been confirmed."

"Are you saying that the SIID Foundation might possess 'prophetic abilities' from the Day of Apocalypse or 'human power' that surpasses the current level of civilization?"

"Yes."

"Professor Ye also thinks so?"

Lin Xian said, "She expressed her curiosity. I have synchronized some of this information now, and it should be more complete when you wake up. At that time, it can help the Phoenix Society to sweep through the Crimson World. As for the humans under the Abyss of Star 13, Professor Ye and I both think that this may be unusual. After all, this was obtained from the perspective of the corpse driver. The Phoenix Society's Noah and Phoenix City have already sent people to investigate, and we may soon have some results."

"You brought an elite team to investigate this too?" Chu Yan asked, looking at him.

Lin Xian shook his head: "Not entirely. I have my own purposes, which I haven't told Professor Ye."

"What is your purpose?"

“Mechanical abilities,” Lin Xian said, looking at Chu Yan. “You’ve entered my consciousness, so you know my mechanical abilities, how to improve them, how to expand them, including my Black Star Forge. I’m currently putting the entire Sky Train inside for weaponization. Similarly, I’m collaborating with Shinji Mochizuki, combining Project Monarch and bio-engineering technology to create new suppressor systems and bio-engineered weapons, including my robot army…”

“I know…” Chu Yan’s lips curled slightly as she looked at the scenery: “You have quite a few secrets, even more than Julius.”

Lin Xianwen said calmly, "Yes, Hell Chrysanthemum, Heterogeneous Cube, Silver Dragon Ten Thousand Mistakes, Blood Vine, but there is a problem, a problem that Mochizuki Shinji reminded me of."

Chu Yan turned her head: "You believe your mechanical abilities are developed by some higher-dimensional civilization combined with current human industrial civilization. Even if they aren't, with your current abilities, even if you acquire all the blueprints and materials, at most you'll only..."

"At most, it's just a production line slightly smaller than the one in Silent City." Lin Xian said directly, "In the battle of Dawn City, the flesh-and-blood armor of the Crimson World, the top-tier mechs of the Phoenix Society's Emperor Project, and the former South Heaven Gate, we relied on these to repel the Darkness's probing. In Professor Ye's words, this may only be a temporary balance in the fog, and the Darkness's counterattack will definitely come again."

Chu Yan remained silent for a moment.

“I’ve been thinking about how mechanical abilities can break the deadlock. If I can only manufacture equipment that the Phoenix Society, Project Emperor, and Xinghua Heavy Industries can all manufacture, or weapons that already exist, then essentially my mechanical abilities won’t change anything. When the darkness counterattacks, I may not be able to do anything.”

Lin Xian stared ahead: "So I'm thinking, what would happen if my mechanical abilities were upgraded to level 7, 8, or even 9 and finally awakened? What if the SIID Foundation really possesses 'human power' that surpasses the current level of civilization? What if my mechanical abilities really come from a higher-dimensional civilization? Or what if my research and development center blueprint can be upgraded to break through the limitations of the current civilization..."

As he spoke, he slowly looked at Chu Yan, and said in a calm yet expectant tone, "Only in this way can we truly possess the power to fight against the darkness, only in this way can we truly achieve a deterrent effect on civilization, only in this way can we truly become..."

"Sword Bearer!"
