Doomsday: I Build an Infinite Train.

Chapter 405 The Sea of ​​Stars
High in space, the massive photovoltaic wing of the South Heavenly Gate paused for one second before resetting. When the control command message was activated again, the thousands of photovoltaic wings flipped again.

The four standard decoded texts appeared clearly on the monitoring screen of the deep space monitoring station and were projected into the command hall of the Zhentian ship.

At that moment, the air seemed to fall completely still. Countless people looked at the large monitoring screen and slowly stood up one after another. Every face on everyone's face was filled with shock.

"You're not allowed to resist? Is this a threat to us?" Liu Shijie said in horror.

"What does this sentence mean?" Information engineer Wu Junping also asked with a grave expression. "Is it the Dark Civilization's response to the Dawn City incident?"

"But this message was received on Apocalypse Day..."

"That statement is meaningless. When faced with a life-or-death threat, how could one not fight back?"

In an instant, countless whispers could be heard within the Moon Gazing Project team, and an uneasy and tense atmosphere began to permeate the air.

Chu Yan frowned and looked at Ye Lan beside her. She noticed that Professor Ye was staring intently at the four large characters for a while before speaking.

"I think the key point is who the subject is in this information context?"

Chu Yan's eyes narrowed upon hearing this: "You mean, this message might not necessarily have come from the Dark Civilization?"

Many people turned to look at him at that moment.

Ye Lan shook her head: "It's highly possible, but we can't be sure. First, if this information came from the day of the Apocalypse, we only just finished observing it, so it might not be related to the resistance in Dawn City. Second, the context is unclear; who is this message addressed to? Is it a warning or a cautionary tale? We don't know. Third, it's impossible for humans to accept such a death warrant, so its meaning is also unclear..."

As soon as Ye Lan spoke, everyone around her looked puzzled.

"But for now, we can only take this as a warning from the dark civilization to humanity." Huo Jiang, the commander of the Iron Guard Brigade, said with a solemn expression: "This is the most reasonable guess. As for the context or word choice, we have discussed this point before, which is that the way of thinking and the logic of behavior of the dark civilization are completely different from those of humans."

Ye Lan nodded, then looked at Yang Xu, who had been silent all along, and asked, "Chief Engineer Yang, what do you think?"

"I agree with General Huo's opinion." Yang Xu took a deep breath, his gaze thoughtful, and then spoke.
"However, Professor Ye is right. We cannot take the receipt of this message on the day of the apocalypse as a strong reference. If this dark matter information has the characteristics of a quantum superposition state and is not affected by the time dimension, then it is very likely that this information comes from a higher dimension."

Huo Jiang looked puzzled and turned to look at him: "Gao Wei? Chief Engineer Yang, you might want to elaborate."

Yang Xu adjusted his glasses and explained, "Simply put, time is a linear relationship for us humans, that is, three-dimensional beings. We live on the axis of time, we can't change time, we can't change the past, and we can't see the future. But if we raise the dimension to the fourth dimension, then all the 'present' moments of time can be observed. In other words, four-dimensional beings can see the beginning and the end of things at the same time. 'They' see us as if we are watching a TV series, and the timeline is like a progress bar, allowing us to observe our past and future at any time."

Ye Lan nodded and said, "Yes, assuming this message is not affected by the time dimension, then it means that the 'existence' that sent this message already knew the fate of the 'recipient.' From this perspective, the meaning of the phrase 'No resistance allowed' becomes very different."

"So you just said that warning and admonition have two different meanings?" Chu Yan asked.

Ye Lan nodded, and Chief Engineer Yang then explained.

“Yes, theoretically speaking, since we captured this message, we are the ‘recipient.’ But the problem is, if the dark civilization possesses higher-dimensional power, logically there is no need for it to send us such a message, because our fate is predetermined.”

“But our outcome is predetermined, so Dawn City won’t be able to launch a successful counterattack, and Star Abyss won’t express any ‘doubt’?” Chu Yan realized at this moment.

Ye Lan took a deep breath and said calmly, "That's true, but these are all just our guesses."

She looked at the large monitoring screen as she spoke: "Whether this is a warning or a caution, whether this information comes from a dark civilization or some other higher-dimensional being, it is an important reminder for us."

"It reminds us that humans are ants."

As soon as he uttered those words, the air in the command hall seemed to freeze. Ye Lan's gaze swept over everyone, then settled on Yang Xu.
"Chief Engineer Yang, from now on we must constantly monitor the changes in the photovoltaic wing surface of Nantianmen. Theoretically speaking, the future is already happening while we are doing this..."

……

Yongcheng Port connecting port, number infinity.

Viola projected the image from the South Heavenly Gate, leaving everyone on the Infinite somewhat puzzled.

"I feel a little scared..." Sasha's face was a little confused, and the other girls also looked apprehensive. Shiori hid behind Ryunosuke.

"It feels like I'm having a conversation with a strange civilization." KIKI crossed her arms. "Is that all?"

“It looks like a provocation,” Qian Dele said.

"What does that mean? Is it meant for us?" Luo Yang asked with a worried look, while Lü Chang shrugged, indicating that he didn't understand at all.

Monica's gaze remained calm as she spoke, "A civilization capable of wiping out Earth doesn't need provocation. This sounds more like an order."

Chen Sixuan looked at Lin Xian and noticed that Lin Xian's expression was also somewhat blank.

"Lin Xian."

"Ok?"

"What do you think?"

Lin Xian took a deep breath and looked at Ding Junyi: "I don't quite understand, I'll have to ask Director Ding."

After she finished speaking, everyone's eyes immediately fell on Ding Junyi.

Ding Junyi, with her hands in her pockets and a calm expression, said, "Do you have some misunderstanding about scientists? I'm in the field of biology, I'm not good at astrophysics, and my knowledge of quantum mechanics is limited to casual conversation."

Lin Xian smiled and said, "Aliens are also living beings, and strictly speaking, they fall within your research scope."

Ding Junyi adjusted her glasses helplessly: "The Phoenix Society's Stargazing Group should be in urgent discussion right now. However, based on the information you provided, the quantum superposition state under the time loop involves spacetime distortion or black hole energy extraction such as the Penrose process to achieve quantum entanglement communication. This power has reached the level of a Kardashev Type II or even Type III civilization, approaching or already possessing high-dimensional technology. So, the key issue for us now is 'who' sent this message, and to 'who'?"

"What if it was sent to us?" Shuqin asked.

Ding Junyi shrugged: "Then we can only pray. Humanity is not even sure if it can defeat the Dark Star Abyss, and even if we were given another thousand years, we would have no chance of winning against this power."

After saying that, she turned around to go back to continue her research, but Lin Xian stopped her: "Director Ding, do you think this message wasn't transmitted by the Dark Civilization?" "I'm not sure, it's contradictory." Ding Junyi turned around and said to him, "Currently, the information is limited, we can't make many guesses, and it doesn't mean much to us."

Lin Xian pursed his lips and nodded, saying, "Okay, you're right."

He then asked Viola, "Viola, if the civilized power that Director Ding mentioned exists, can it calculate humanity's chances of winning?"

【0】

Viola maintained a dignified demeanor. Everyone knew she had performed calculations on the order of hundreds of billions, yet she uttered those words as if without any hesitation.

"Wow, that's impressive." Qian Dele smiled. "Luckily, it's not some 1% hope that requires several generations to struggle for, so I can finally sleep well."

After saying that, he yawned, turned around and patted Lu Chang and Luo Yang on the shoulder: "Let's go, sleep a little longer, we have to take turns on duty later."

The information observation at Nantianmen ended, but the strange four-word message kept buzzing around Lin Xian's ears like a mosquito, making him restless.

So Lin Xian gave up on staying up all night to devour food, went back to his car to catch up on some sleep, and set off after dawn.

The nights by the sea were quite peaceful except for the howls of zombies. Lin Xian had gotten used to falling asleep to the scratching sounds of zombies outside his window, and the Infinite, with its sturdy armor, still gave him a great sense of security.

Many times, Lin Xian even missed the days of falling asleep on the train. Although he was constantly on the run from danger, he had gotten used to being with danger. The days of building a solid fortress with his mechanical abilities were actually quite tempting.

After the four-character signal from Nantianmen, Lin Xian didn't know if the world would change as a result, nor did he know where the original Blue Star and the wandering human civilization would go.

Before falling asleep, Lin Xian looked out the window at the dark night sky and suddenly thought of the Natural Selection and Deep Blue. He wondered where these two starships, which carried the mission of mankind, were now sailing. After entering the vast and boundless deep space of the universe, perhaps only faith could overcome 1500 years of loneliness.

Drop drop, drop drop.

The long-awaited alarm clock rang, and Lin Xian felt a warm breeze on his face. He slowly opened his eyes, and sunlight shone through the gap in the sun visor he had opened last night. The sky outside was clear and blue, while hundreds of rotting zombies still surrounded the car window.

"Good morning."

Lin Xian's gaze swept across the faces of the zombies, then he checked the time.

10:20
It was quite early. The dark tide of Star Abyss No. 8, carrying a salty sea breeze from the Pacific Ocean, swept across the world. Lin Xian got up and found that everyone except Qian Dele and the others who were on night watch had already gotten up.

Because there are not many people, the food reserves on the Infinite are quite abundant. In addition, with the dark energy filtration technology, water resources on the vehicle are no longer scarce. The A1-level subcritical reverse osmosis water purifier installed by Lin purifies the water to drinking water quality for use by the whole vehicle.

In carriage 2, Sasha and KIKI were already eating bread, while in carriage 3, Ding Junyi was studying plants. Xiao Yuan and Miao Lu had gotten up early to help out. Ding Junyi's main focus was now on the cultivation of plants in the disaster-prone and green-plant carriages, which would help her evolve and explore her superpowers.

In carriage number 5, Mo Xiaotian was practicing controlling lightning arcs at Huo Ge's request early in the morning, his fingers crackling incessantly. Huo Ge was playing chess with Ryunosuke on the side, while Da Lou was studying his Black Dragon Armor.

"Team Leader Lin, the weapons, equipment, and vehicles have all been inspected and are ready to depart at any time."

Ning Jing sent a message that she and Shu Qin are now mainly responsible for the safety inspection of the train. Originally, Ning Jing was in charge of this aspect on Longshan No. 1. Meanwhile, the two young people, A Bai and Xiao Qing, are basically idle. Luo Yang, Lü Chang, and Sa Sha have recently been researching some kind of underwater mechanical device. They even had Viola help design the blueprint, and Lin Xian helped manufacture it.

The remaining money was kept in Monica's room, connected by a communicator, so Lin could contact them anytime if needed.

"Alright, get ready to depart. We'll head to Takor deep-water floating harbor first, and we should dock at Sea Rock Island tonight." Lin Xian went to the cockpit and started the Infinite together with Chen Sixuan.

Woo!
With a humming sound, the magnetic levitation array beneath the Infinity train began to activate, and the entire train slowly rose into the air before moving forward.

"Yay!" came KIKI's cheer from the communicator.

"I heard that after the Apocalypse Day, many islands became popular refuges. The beaches on Sea Rock Island are nice; I hope I don't encounter any monsters~"

"What, even if it's the end of the world, you still want to sunbathe on the beach?" Chen Sixuan replied with a smile.

At this moment, Lu Xingchen's voice came: "That's a great idea, I agree, I agree!"

Chen Sixuan listened with a smile and looked at Lin Xian. Lin Xian smiled helplessly and took a deep breath: "Let's go, let's cross the ocean!"

The Infinity began to accelerate, merging from the parking track into the main orbit of the planet. All the sunshades were opened, and then it drove eastward into the ocean section of the planet. Countless zombies were smashed aside. This black heavy train drove into the paralyzed traction hall, and after passing through a short period of darkness, it suddenly rushed out from a huge exit!

Wow!
In an instant, the sea breeze howled, and the view outside the porthole turned into a vast expanse of blue. It seemed as if only this giant, straight man-made sea track remained between heaven and earth, and an endless sense of openness rushed into everyone's hearts.

Sasha, KIKI, Xiaoyuan, everyone, even Director Ding couldn't help but stop their work and look out the window at the azure sky that suddenly filled the sky and earth.

Inside carriage number 9, Monica, dressed in an elegant long dress and wearing sunglasses, sat by the window, gazing at the vast ocean with a smile on her lips.

Qian Dele had already woken up, opened the window and looked outside, smiling meaningfully.
"Extraterrestrial civilizations and the end of the world are irrelevant. We should take advantage of our remaining life and the fact that this planet hasn't been destroyed to take a good look around."

In the cockpit, Lin Xian and Chen Sixuan looked at the vast scenery outside the porthole and couldn't help but exchange glances.

"Teacher Chen." Lin Xian noticed that Chen Sixuan seemed nervous and reached out to take her hand. "Are you scared?"

Chen Sixuan shook her head
"You used to be afraid, but you're not as afraid now?"

"why?"

Chen Sixuan looked at him with great satisfaction and said, "My power armor can go up into the sky and down into the water, the Infinity has a deep-sea propulsion module, and the Sky Train can soar into the sky, and... there's you too, so it seems like I'm not so afraid anymore."

"Crossing the Pacific Ocean is only the first step."

Lin Xian smiled, then looked at the vast ocean ahead and said in a stern voice.

"We'll travel to the stars and the sea together someday!"
