In the vast expanse of the universe, a cosmic train, resplendent with shimmering lights, hurtled through the star-studded void. Its sleek, silvery body reflected the distant starlight, creating a dazzling spectacle as it traversed the celestial highways between worlds.

Inside one of the train's luxurious compartments, March 7th and Stelle were engaged in animated conversation, having just bid farewell to the imposing silhouette of the Herta Space Station, which now receded into the cosmic distance behind them.

March 7th, her vibrant pink hair framing her face, blinked her lively, expressive eyes. A smile of pure excitement played across her lips as she turned to her companion. "Wow, we're about to head to our next destination! Aren't you feeling absolutely thrilled right now?" she asked, her voice brimming with enthusiasm.

Suddenly, as if struck by a revelation, March 7th's eyes widened even further. "Oh, that's right!" she exclaimed, her excitement palpable in the air. "This is your very first journey, isn't it? That must mean you're experiencing double the excitement!"

Stelle, observing the bubbly pink-haired girl beside her, straightened her posture, puffing out her chest with a mix of nervousness and determination. "I'm ready!" she declared loudly, her voice echoing slightly in the train compartment. "I'm absolutely ready for this adventure!"

"That's the spirit! You're really fired up, aren't you?" March 7th beamed, leaning casually against a nearby storage unit. Her eyes twinkled with amusement as she continued, "You know, I was just as excited the first time I experienced a space jump. But now, I'm much more composed about it all."

With a playful wink, she added, "Don't worry, you'll get used to it soon enough. Before you know it, you'll be a seasoned and reliable passenger just like me." As she spoke, she nodded sagely, as if imparting great wisdom.

Suddenly, Stelle's attention was drawn to something outside the window. Her hand rose slowly, finger pointing towards the cosmic expanse beyond the train. "What... what is that?" she murmured, her voice barely above a whisper.

Puzzled by Stelle's sudden change in demeanor, March 7th turned her head, following the direction of Stelle's outstretched finger. Her gaze fell upon the train's window, and what she saw made her gasp in astonishment.

"What are you talking abo— Oh my stars!" March 7th's exclamation of disbelief cut through the air as her eyes registered the sight before her. The once pitch-black canvas of space, dotted with countless stars, had suddenly been transformed. A colossal screen of light, impossibly vast, had materialized amidst the cosmic tableau.

This ethereal apparition hung suspended in the void, reminiscent of an immense silver wall stretching across the stars. It emitted a light so intense and otherworldly that it sent shivers down March 7th's spine. Never before had she witnessed such a phenomenon in all her travels across the galaxy.

March 7th's eyes grew wide with wonder, her mouth agape in an expression of pure amazement. The sight before her defied all logic and understanding, filling her with a potent mixture of curiosity and awe.

"Whoa! What in the universe is that?" she cried out, her voice trembling with excitement and a hint of trepidation. Without missing a beat, she called out to her fellow passengers, "Uncle Yang! Jing Yuan! You've got to come see this!"

Meanwhile, in the observation car, Jing Yuan had already taken notice of the strange occurrence unfolding in the cosmic expanse. Her usual calm demeanor was replaced by one of stunned fascination as she gazed upon the enormous screen that had materialized out of nowhere.

"This is... unprecedented," Jing Yuan muttered, her eyes fixed on the mysterious apparition. "I've never encountered anything like this in all my years of space travel."

As if on cue, a chorus of notification chimes rang out from the communication devices of everyone aboard the train. Glancing at their screens, they found that a new chat channel had mysteriously appeared, bearing the intriguing title "Viewing Room."

The channel's description read: "Viewing Room Rules: Random images from the future or past will be broadcast across the universe. Trailblazers may comment without restriction. Ordinary individuals may have limited commenting privileges."

Below this cryptic message, a lively chat had already begun to unfold:

[Hemiko: Hey, is anyone else seeing this? Who's behind this? It's kind of exciting, isn't it?]

[Fu Xuan: This defies all logic. My Astromancy cannot discern the nature of this phenomenon. How is this possible?]

[Jing Yuan: Patience, Fu Xuan. Let us observe and gather more information before drawing conclusions.]

[Fu Xuan: Understood, General. I shall restrain my curiosity for now.]

Despite her reluctance to admit defeat, Fu Xuan had exhausted the full capabilities of her Astromancy in an attempt to unravel the mystery before them. Her inability to glean even the slightest bit of information was a blow to her pride, but she recognized the wisdom in Jing Yuan's words. Sometimes, the best course of action was indeed to wait and observe.

[Silver Wolf: Fascinating technology... It's infiltrated even my secure systems. I can't begin to comprehend how it works.]

[Herta: What in the name of science is going on here?]

In the depths of space, the massive Herta Space Station hung suspended among the stars. Herta's android avatar stood at a large observation window, her gaze fixed intently on the shimmering screen that had appeared in the cosmic void.

Curiosity burned within Herta's circuits. This enigmatic screen defied all her attempts at analysis, a fact that both frustrated and intrigued her brilliant mind. For a genius of her caliber, encountering something she couldn't immediately understand was a rare and exhilarating experience.

A daring hypothesis began to form in her digital consciousness. "Could this be the work of some unknown Aeon? If so, how utterly fascinating!"

The thought sent a surge of excitement through Herta's systems. She had always been driven by an insatiable desire to explore and understand the unknown. Normally, her interest in new discoveries would wane quickly once she had unraveled their mysteries. But this... this promised to be a challenge worthy of her intellect.

As for her previous project involving the Stellaron hunter with a Stellaron core... well, that could wait. After all, she had already secured permission to study the subject. There would be time for that later. Right now, all of Herta's considerable mental resources were focused on the enigmatic screen before her.

[Sampo: Well, well! I never thought I'd see so many familiar faces gathered in one place like this. It's a pleasure, truly!]

[Seele: Who are you all? Sampo, is that really you?]

Seele's message appeared quickly, recognizing the familiar name.

[Sampo: Why, if it isn't the lovely Miss Seele! Good evening to you, my dear.]

[Bronya: This is a most peculiar construct. I've never encountered anything like it. Who are you people?]

On the distant, frozen world of Jarilo-VI, the inhabitants of Belobog found themselves in possession of strange new devices. These mysterious gadgets had appeared without warning, materializing in pockets, on desks, and in backpacks throughout the city.

As curious citizens activated these devices, they were greeted by an astonishing sight—a chat room and an enigmatic channel displayed on holographic screens.

[Cocolia: Bronya, return to base immediately.]

Upon seeing this message, Bronya, who had been leading a patrol of soldiers, paused for a moment. Recognizing the gravity of the situation, she quickly made her way back to the Silvermane Guards' headquarters.

[Stelle: Hello, everyone! I'm the Galactic Baseball Star! It's a pleasure to make your acquaintance.]

[March 7th: Oh, come on! What are you saying, you silly goose?]

March 7th playfully ruffled Stelle's hair, a mix of amusement and concern in her eyes. She couldn't help but wonder if the excitement of their journey had gone to her friend's head, causing her to spout such nonsense.

As this surreal scenario unfolded, similar events were transpiring across the universe. From the Xianzhou Alliance to the Penacony, and countless worlds in between, the mysterious "Viewing Room" channel appeared on communication devices everywhere.

Even on planets like Jarilo-VI, where advanced interstellar communication technology was scarce, people found themselves in possession of devices capable of accessing the chat room. They could look up at the sky and see the celestial broadcast, or use their new gadgets to watch and participate in the ongoing conversation.

People gathered in groups, excitedly discussing this unprecedented occurrence, eagerly anticipating what might happen next in this cosmic spectacle.
