When this thought crossed his mind, Lin Xian couldn’t help but break into a cold sweat, so he simply chose not to dwell on it. He felt that the best course of action in the current situation was to go with the flow. This Jingyuan Vortex Channel was like an underwater highway and was safer than fleeing in panic. Now, breaking through the surface wouldn’t lead to land discovery, nor could they take off with the Sky Dome. It was better to let nature take its course, which was the wiser choice. Besides, he was physically exhausted, and there had been no personnel reduction on the Infinity and Northern 09, which was a relief, so he decided to get some sleep.

Lin Xian’s heart grew larger, although outside was the abyss, he believed he could surely fall asleep.

Unexpectedly, when Lin Xian headed towards Car No. 1, Shi Zhi hurriedly followed with small steps, trailing like a nurse holding an IV drip bottle, continuously using her Healing Ability to help Lin Xian recover.

Taking two steps, Lin Xian stopped, turned around, and said,

"I’m going to rest for a while, Shi Zhi, you go help others."

Shi Zhi shook her head, "No, I sense there’s something wrong with your spirit, and my intuition tells me I must fully restore you."

"Spirit problem?" Lin Xian frowned, raising his gaze to look at Chen Sixuan, "Do you think I have a problem?"

Chen Sixuan’s face showed concern, "Viola and I are here watching, you better listen to Shi Zhi."

Lin Xian looked at Shi Zhi and found the young lady resolute, so he said nothing and walked out of the cockpit, entered the bedroom in Car No. 1, removed his Power Armor, and fell back into the soft bed, sighing as he gazed at the ceiling. The bedroom had a Star Dust Glass porthole, and he looked outside, finding that there was no longer any sign of the luminous blue plankton, only darkness remained, with only the light inside the car illuminating it.

Silent and without a trace, yet surrounded by a massive high-speed ocean current, outside lay a bottomless abyss, with no fish or shrimp in sight.

Loneliness, dead silence, suffocation, endless unknown, deep-sea fear.

Shi Zhi followed Lin Xian into the bedroom, then sat on a chair by the bed. Although somewhat fatigued, she continued to heal Lin Xian tirelessly, from start to finish without speaking.

"Did you ever imagine traveling by train into the deep sea?" Lin Xian’s words seemed directed at Shi Zhi, yet also sounded like self-talk.

Shi Zhi nodded, but Lin Xian didn’t see it, as if there was no response.

"Shi Zhi, danger lurks everywhere outside, aren’t you afraid?" Lin Xian asked, looking at the darkness outside the porthole.

"No," Shi Zhi said softly.

"Why?"

"Because..." Shi Zhi pondered, "Shinji once said, even if the Blue Star ceases to exist, the atmosphere is gone, the oceans vanish, Silent City will fly among the stars, he’ll create a safe haven, as he journeys through the star systems with us. We can withstand any danger because Silent City is our home. This feeling... is wonderful."

Lin Xian fell silent for a moment upon hearing this, murmuring, "Yeah, it sounds really nice. I have had similar thoughts."

To build a robust steel train, incorporating residential cars, resource cars, medical, cultivation, energy, production, and other functional cars into a fortress train, fully armed, unstoppable, fleeing eastward along the 320,000 kilometers of Star Orbital, even if halted midway, relying on the fortress-like Armor, it could repel swarms of zombies and mysterious attacks in the dark!

It’s romantic enough, and crazy enough!

Thinking back, Lin Xian found Mochizuki Masashi’s idea deeply inspiring. Perhaps his Mechanical Superpower should venture in this direction.

For example...

The one in the Research and Development Center, what is it...

Planet Titan?
