Inside the Solace Book House, the light within the shop gradually faded.
"Looks like… I really came back!"
Looking around at the familiar interior of the manga shop, surprise flashed across Yae Miko's eyes.
Although she often visited Tenshukaku, it had never been in her own identity.
Not to mention—it had been Inazuma from 500 years ago!
So during the soul exchange, she had felt a faint sense of awkwardness.
Now that she had returned—that feeling was finally gone.
"Ah… my own body is definitely more comfortable."
Yae Miko stretched lazily in satisfaction.
But when the corner of her eye caught sight of Raiden Ei, she froze.
Why was Ei here?!
Could it be—that something happened during the half day she had been away?
Yae Miko frowned in thought.
"Could Boss Han have opened a branch store in Inazuma?"
Thinking of what happened in Liyue, Yae Miko suddenly came up with a possibility.
Only that could explain it.
As for why Ei was here rather than the Raiden Shogun—she guessed some sort of incident must've occurred.
She could ask later.
"Makoto, are you alright?"
At that moment, Raiden Ei approached with concern.
Earlier, she had seen dazzling light surrounding her sister's body.
Worried something had happened, she had rushed over—only to be blocked by some mysterious force.
She only managed to approach after the light disappeared.
"Makoto?"
A playful glint appeared in Yae Miko's fox-like eyes.
From that form of address, it was obvious—the sisters had already reunited.
Thinking about how her old friend still hadn't recognized her, Yae Miko's eyes turned mischievous.
She coughed lightly.
"Ahem. Ei… after all these years apart, couldn't you at least call me 'Big Sister' once?"
"Huh?"
Ei blinked and froze adorably.
In the past, when she called her sister by name, Makoto never reacted.
So why was she suddenly asking for that?
"Could it be… after seeing the future me from 500 years later, her emotions became stronger?"
Ei quietly thought to herself.
But—it was only calling her sister once.
Not a big deal.
Thinking this, Ei looked at Makoto with emotion and softly said:
"Big Sister."
"Ah, such a good girl."
Yae Miko smiled brightly and pinched her friend's cheek.
That title made her feel refreshed all over.
This trip truly hadn't been wasted.
"Wait… you're not Makoto. Y-You're Miko?!"
The sudden shift in temperament—and that familiar fox-like smile—finally made Ei realize.
Disaster.
She'd been tricked.
She got fooled by this fox again!
"Ei, my dear little sister—how about calling me 'Big Sister' one more time?"
Yae Miko leaned in slightly and teased with a grin.
Being able to take advantage of her old friend through identity alone—she was in an excellent mood.
"Not happening. Hurry back. That witch—Alice—is already in Inazuma."
Hearing this shameless fox continue teasing her, Ei's face darkened.
Then she turned and walked toward the exit.
As for the "Big Sister" thing—she decided not to pursue it.
After all, being able to meet her sister from 500 years ago—
Ei still felt deeply grateful.
"What? That witch actually came?"
Hearing the news, Yae Miko frowned.
Her expression even became unusually serious.
That witch—was one of the rare people even Yae Miko found difficult to deal with!
When she was little, she'd been bullied by Alice more than once!
You could say many of her embarrassing memories involved Alice.
Though—she had successfully gotten revenge once.
By getting Alice completely drunk.
"I should go back and properly meet her."
Interest flashed across Yae Miko's face.
Back then she was young and got pushed around.
But now…who would be bullying whom?
Thinking this, Yae Miko turned and walked toward the counter.
After all, if she wanted to return to Inazuma—she still needed Boss Han's help.
"Welcome back, Miss Miko."
Looking at the familiar cheeky fox, Han Feng smiled.
"Thank you, Boss, for granting me this opportunity. Miko is deeply grateful.
If there is a chance in the future, please visit the Grand Narukami Shrine. Miko would gladly let you experience the flavors of Inazuma."
Yae Miko bowed respectfully.
In front of Han Feng, her attitude was unusually proper.
A casual reward—and she could travel 500 years into the past.
One could imagine how mysterious and powerful Boss Han truly was.
Faced with an existence even more unfathomable than a god—
she naturally had to maintain sufficient respect.
If Ei saw this scene, she'd probably be speechless.
Whose familiar are you supposed to be?
"No need. A fair exchange. Nothing more."
Han Feng lightly shook his head.
Though internally—he couldn't help but sigh.
Who would've thought that cheeky fox would become this polite?
It felt strangely out of place.
"You came over because you want to know what happened after the soul exchange?"
"No. I can ask Ei about that later. I simply wish to return to Inazuma, so I ask Boss for a favor."
Yae Miko shook her head slightly.
"I see."
Han Feng didn't refuse.
After all—being allowed to witness such an entertaining soul exchange drama—this small favor was nothing.
He casually waved his hand.
A ray of light descended onto Yae Miko.
"Thank you, Boss."
Yae Miko bowed once more and prepared to leave.
But then she suddenly remembered something.
Turning back, she asked:
"Boss—if Ei's sister truly changes the tragedy of the past…
what impact would that have on present-day Inazuma… and Teyvat?"
"Impact…"
Han Feng thought for a moment.
Time was a terrifying thing.
Changing the future and changing the past were entirely different.
Even the slightest alteration—could trigger enormous consequences.
Like a novel he once read in his previous life.
Someone wrote a letter to their past self—and accidentally released a demon.
Eventually it caused a world-level crisis.
After pondering briefly, Han Feng said:
"For Teyvat as a whole, the impact probably won't be too large.
The biggest changes would be in Inazuma.
If Raiden Makoto succeeds—many of your memories could change.
Even the daily lives of Inazuma's people could become completely different.
But time also has a certain corrective force.
So the exact outcome…
will only become clear after the Khaenri'ah war."
"I understand. Thank you, Boss."
Yae Miko nodded lightly.
She roughly understood his meaning.
Overall, not too much would fundamentally change—but adjustments would happen.
For example—
Inazuma might still pursue Eternity.
The Raiden Shogun might still appear as usual.
But perhaps—the Vision Hunt Decree and the Sakoku Decree would never come to exist.
