In the Honkai: Star Rail world, different "worlds" also exist.
However, here, "world" doesn't mean planets or universes, but refers to small areas within star systems isolated by imaginary number space.
According to imaginary tree theory, the Honkai: Star Rail world has countless small worlds that, like leaves, grow on the same tree but are isolated from each other and cannot contact one another.
Only Aeons, or major interstellar forces blessed by Aeons, or through star tracks laid by the Astral Express, can break through imaginary number space barriers, traverse the stars, and travel from one small world to another.
Representative forces include the Interastral Peace Corporation worshipping Preservation, the Xianzhou Civilization worshipping the Hunt, and naturally the Astral Express worshipping Trailblaze.
As an Astral Express member, March 7th had naturally seen many small worlds along interstellar routes.
Different worlds posed no conceptual difficulty for her.
However, after patiently listening to Tohsaka Rin's explanation, even she understood one thing.
The worlds Tohsaka Rin spoke of differed from her own understanding.
So-called interdimensional chat groups connected individuals from completely different universes beyond the observable universe!
[March 7th: "Is this real?"]
March 7th immediately became excited.
For Trailblazers, nothing was more thrilling than other universes.
That represented unknown territories untouched even by the Astral Express, unexplored even by the Trailblaze Aeon Akivili.
If she could reach such places, wouldn't she become a Trailblazer even greater than Himeko-neesan?
[Tohsaka Rin: "Of course it's real. If you don't believe it, you can come over and see for yourself."]
[March 7th: "Ooh! Can this chat group really travel to other universes?"]
The pink-haired girl's eyes sparkled, completely interested.
[Tohsaka Rin: "Of course. As long as someone's willing to invite you and spend certain points."]
[Tohsaka Rin: "However, some worlds are still dangerous. People without power shouldn't venture there rashly."]
After detailed explanation, the twin-tailed young girl suddenly remembered something.
[Tohsaka Rin: "By the way, since you're in an interstellar civilization, your strength should be pretty good, right?"]
Anyone daring to traverse the stars shouldn't be ordinary people.
Hearing this question, the pink-haired girl paused slightly.
[March 7th: "Strength?"]
She pondered for a few seconds.
Among the current Astral Express crew, her strength ranked a solid fourth.
Though the train crew currently only had four people—not counting Pom-Pom.
As dead last, she obviously couldn't match Dan Heng or Welt Yang, nor did she have the courage to challenge Navigator Himeko.
If the other party questioned her strength, she might have gotten defiant with her personality, but Tohsaka Rin clearly showed concern, and she understood unknown universes would definitely have unknown dangers.
So after contemplating, she drooped her head dejectedly.
[March 7th: "My strength is average. I can only fight small fries. But if Himeko-neesan and Uncle Yang could come with me, then no problem!"]
She had complete confidence in those two seniors' abilities.
[Kanae: "Only fighting small fries? Seems like the interstellar age isn't as exaggerated as Rin said!"]
She immediately believed March 7th's words.
[Tohsaka Rin: "After all, humans are still humans!"]
The twin-tailed young girl also sighed in relief.
She'd been worried about another Jibril-type who played pig to eat tiger, but now it seemed otherwise.
Thinking this, out of habit from verifying Jibril's strength, she still checked March 7th's personal profile.
Then she froze.
[Tohsaka Rin: "???"]
[Tohsaka Rin: "You call Fourth Tier Continental Sinking level strength 'fighting small fries'?!"]
[Tohsaka Rin: "@March 7th"]
[Tohsaka Rin: "Are your small fries made of gold, or is their meat golden?"]
The twin-tailed girl frantically complained.
Damn, she knew new members weren't that simple!
[Kanae: "..."]
[Kanae: "Another monster-level new member!"]
Kanae was also shocked.
With Ryuga already at Fifth Tier, Fourth Tier didn't sound particularly impressive, but that didn't prevent the new member from becoming second-strongest alongside Jibril upon joining.
Besides that, when Jibril joined, she'd been quite arrogant, even attempting to challenge Ryuga.
Though ultimately subdued, Jibril had considerable confidence in her own power.
How did it become "only fighting small fries" when March 7th reached Fourth Tier?
Was the so-called interstellar age actually this terrifying?
Even Jibril had to pay more attention to the new member.
[March 7th: "Fourth Tier? Continental Sinking?"]
Faced with everyone's surprise, March 7th was still confused.
Only after Kanae carefully explained the chat group's power rankings did she understand.
The pink-haired girl immediately waved her hands.
[March 7th: "Although I don't know how it's calculated, my strength really isn't that exaggerated! I definitely can't single-handedly sink continents!"]
She knew her own capabilities. Though she could easily handle Antimatter Legion's Outer Universal Flames and Outer Universal Ice, plus elite monsters like Voidranger Trampler, she truly lacked large-scale terrain-altering abilities.
[Tohsaka Rin: "But the chat group's evaluation won't be wrong."]
The twin-tailed young girl was momentarily puzzled.
The chat group definitely had no issues. Could the other party be lying? She didn't seem like she'd shown that level of cunning... air-headedness?
While she puzzled, lurking Jibril jumped out to explain.
[Jibril: "Sinking continents is just an illustrative description of destructive power. According to chat group rules, even without wide-area destruction capability, reaching corresponding tier strength still earns Fourth Tier evaluation."]
Like Fate or Time gods who couldn't destroy nations with one strike but could still kill same-tier deities, destructive power was an important but not sole strength indicator.
[March 7th: "There are such rules? That makes sense."]
[March 7th: "Though I can't change weather or large-scale terrain, those small fries capable of terrain changes really aren't my opponents."]
[March 7th: "Thinking about it... could I actually be strong?"]
Recalling Outer Universal Flames, Outer Universal Ice, and elite Voidranger monsters that, according to Himeko-neesan, would be god-like to indigenous civilizations and capable of world destruction if encountered on underdeveloped planets.
If comparing this way, she didn't seem that weak?
Somehow, the pink-haired girl suddenly felt confident.
[Tohsaka Rin: "Of course you're strong. I don't even dare let you come to my world—if you accidentally destroyed the country I'm in, wouldn't that be terrible?"]
The twin-tailed young girl complained like this.
Previously, she wouldn't have had such excessive worries, but Jibril's earlier challenge had left them with a warning bell in their hearts.
Ryuga could handle new members, but that didn't mean they could.
If they rashly brought new members to their own worlds without Ryuga's confirmation, and something went wrong, they might not even have time to call for help.
[Kanae: "Makes sense."]
She was convinced by Rin's caution.
Hearing both people's statements, March 7th was a bit confused. Having always been underestimated for her simple nature, this was the first time she was being wary due to her strength.
[March 7th: "You're worrying too much! I'm not the Antimatter Legion—how could I do such terrible things as destroying other people's countries!"]
[Kanae: "Sorry, we're not being wary of you. It's just that this kind of thing has precedent."]
[Tohsaka Rin: "Right! A certain someone once said they wanted to conquer all of us and become the chat group's master!"]
Both pointed meaningfully.
Even if they'd taken benefits and become allies, that didn't mean they'd forgotten Jibril's actions.
[March 7th: "Eh? Sounds like there's quite a story here. Details!"]
Sensing gossip, the pink-haired girl immediately perked up.
[Jibril: "How mean of you two, scaring the new member like that. I can't stand watching this."]
[Jibril: "Our chat group has always been fair and free. Everyone's Ryuga-sama's friend—how could there be such inconsiderate plunderers!"]
The Flügel girl firmly refused to admit such things existed.
She was one of Ryuga-sama's most cherished ones—how could she do such bad things!
[Tohsaka Rin: "You sure there weren't any?"]
[Kanae: "Ahem!"]
[Jibril: "Whatever new products you two release, I'll pay for them!"]
The Flügel girl played her trump card.
[Tohsaka Rin: "Oh my! I must have remembered wrong. Our chat group has no bad people—Jibril is an angel-like girl!"]
[Kanae: "Rin's absolutely right!"]
Under money's power, both immediately changed their tune.
[March 7th: "?"]
[March 7th: "I feel like I witnessed an evil transaction. Are you really not from the Company?"]
The pink-haired girl didn't miss the obvious transaction.
[Madoka: "March 7th-neesan doesn't need to worry. Rin-neesan and the others are like this."]
[Jibril: "Don't misunderstand—I didn't do any dirty deals!"]
[Tohsaka Rin: "I didn't lie either. Jibril really does look like an angel!"]
Although she only looked like one—her personality was more like a reaper.
[March 7th: "The more you deny it, the more suspicious you sound..."]
The pink-haired girl complained helplessly.
[Jibril: "Don't worry about those details. More importantly, March 7th-san, didn't you say you wanted to see beautiful scenery from other universes? If you don't mind, you could come to my place!"]
[Jibril: "Please rest assured, here you can even destroy countries if you want!"]
The Flügel girl had some unknown scheme, desperately inviting March 7th.
[March 7th: "I don't want to destroy countries!"]
The pink-haired girl complained, but was somewhat tempted.
[March 7th: "But are there really beautiful sights? You're not scamming me, are you?"]
She had some caution, but not much.
Such questions naturally couldn't reveal any problems.
[Jibril: "Of course not! I guarantee this is a once-in-ten-thousand-years spectacle. Even in interstellar universes, you might not encounter such thrilling grand scenes. Definitely worth seeing!"]
Seeing this, the other chat group members paused, then grimaced slightly.
They weren't ignorant of No Game No Life's specific situation. This war-torn world approaching apocalypse—what beautiful scenery could there be?
They couldn't even see basic blue skies and white clouds.
This was clearly trying to trick the new member!
If it were only Jibril doing this, the group members would naturally object and not let the new member jump into a pit.
But currently, Ryuga was also in the No Game No Life world. Out of trust in Ryuga, everyone didn't interfere.
[March 7th: "Ten-thousand-year spectacle? Sounds amazing!"]
The innocent girl was immediately fooled.
[Jibril: "I swear by my creator Artosh-sama's name—the scenery here is definitely special enough!"]
[Jibril: "Action beats hesitation—hurry over!"]
[Group member Jibril has sent you an invitation]
[Jibril: "Don't dawdle. If you're late, you might miss it!"]
The series of urgings made March 7th nervous too.
She'd originally wanted to ask Himeko or Welt Yang for their opinions, to see if the two elders would come with her.
But hearing Jibril's urgency, she instinctively thought it was some fleeting scenery.
Plus Jibril's guarantees sounded sincere, unlike lies.
"Forget it. I'll go take photos first, then share them with Himeko-neesan and the others when I get back!"
Her naturally impulsive nature was stirred up.
[March 7th: "Wait for me, wait for me! I'm coming right now!"]
Too late to pack spare clothes, she grabbed her ever-present camera and directly accepted the invitation.
In just a moment, the scenery before her changed from her princess-decorated bedroom to an unfamiliar world.
Under the blood-red sky, the expectant girl excitedly opened her eyes, hoping to witness otherworldly wonders.
Then she saw the Ex-Machina legions before her, flanked by Forest Elf and Dwarf warships, plus Dragonia, Phantasma, and other supernatural beings.
The scent of iron and blood permeated the entire battlefield, with unsettling power fluctuations emanating from the fleets.
March 7th immediately froze.
Where was the promised beautiful scenery? This was clearly the prelude to world-ending war!
