I opened a shop on the Astral Train

March 7 waved at Welt.

"Uncle Yang, Uncle Yang, don't worry! Yuri is a really good guy."

Kevin immediately echoed, "Yeah! Yuri is a nice person."

Dan Heng, standing nearby, added, "I've observed him. There's no ill will toward our train crew in his demeanor. And while the train crew has never rented out carriages before, non-crew members have traveled with us, right?

In essence, it's the same thing—he'll just be following the train from one world to another."

Pam nodded in agreement. "That's right, Pa! If someone wants to travel with the train, the train welcomes them, Pa! We have plenty of empty carriages, Pa!"

Seeing that no one objected, Himeko made the final call. "Alright then, I'll send a message to Yuri right away.

As for the rental carriage, how about the cargo car behind our rest car?"

Everyone agreed, and Himeko immediately sent Yuri a message.

At that time, Yuri was fast asleep in the luxurious room arranged for him by Black Tower.

Thanks to Black Tower's influence, the accommodations were top-notch. The moment the staff heard it was an order from Black Tower, they became exceptionally attentive.

Without hesitation, they arranged for Yuri to stay in the most extravagant presidential suite and even prepared a lavish dinner for him.

—

The next morning, Yuri received the message.

Although space had no distinction between day and night, Yuri still followed a normal schedule—active during the day, resting at night.

There was no sun or moon here, but time still flowed, and using that, he could keep track of when it should be "morning."

After waking up, Yuri enjoyed the exquisite breakfast prepared by the staff before heading to the train.

He arrived at the door of the observation car and knocked.

A moment later, the door opened, revealing Pam standing in the entrance.

"Who are you, Pa? What's your business, Pa?"

Yuri answered, "I'm Yuri. Himeko asked me to come discuss renting a carriage."

Upon hearing this, Pam stepped aside. "Oh! It's you, Pa! Come in, Pa! Himeko and the others are having breakfast, Pa!"

Yuri stepped onto the train and entered the observation car.

As soon as he walked in, he saw Himeko and the others gathered around, enjoying breakfast together.

Kevin spotted him first and waved. "Yuri! You're here!"

Himeko also greeted him. "Yuri, have you eaten yet?"

Yuri walked closer. "I have. Looks like you all are having quite a feast."

At that moment, Welt spoke up. "Why not have some more with us?"

Yuri glanced at him. "I appreciate the offer, but I'm good. By the way, I don't think we've met. What's your name?"

Welt introduced himself. "I'm Welt, a member of the train crew. When you visited yesterday, I was busy checking the supplies. By the time I got back, you had already left."

Yuri smiled. "Well, it's good to finally meet you. You guys finish eating—I'll wait, and we can talk afterward."

He then walked over to the side, sat down, and pulled out his phone to continue adding products to his system catalog.

At the moment, he had over 1,000 items listed.

Welt observed Yuri closely but sensed no hostility from him.

I've lived a long life, and I can read people well enough.

—

A few minutes later, after finishing their meal, the train crew led Yuri to the carriage behind their rest car.

By now, all the debris in the carriage had been cleared away.

Himeko turned to Yuri. "How's this space?"

Yuri nodded in satisfaction. "This will do."

Without another word, he took out the [Store Card] and tore it into pieces.

The moment the card was destroyed, a radiant light engulfed the carriage.

The brightness was overwhelming, forcing everyone to shield their eyes.

When the light finally faded, their eyes widened in astonishment.

The once dull and empty carriage had been transformed into a beautifully designed shop.

To the right, an open kitchen now stood, complete with a bar and several high stools next to a sleek grill station.

To the left, large floor-to-ceiling windows lined the space, next to three cozy booths, each seating up to four people.

Directly ahead, a small bar counter had been set up, equipped with two interactive touchscreens displaying Yuri's entire inventory.

In the center of the room, a long communal table stood, capable of seating ten diners at once.

The entire shop was decorated in warm tones, exuding an inviting and vibrant atmosphere.

Yuri took in the scene and nodded in approval.

The system's Store Card is amazing. This layout is exactly my style.

A space to cook, sell items, and relax with friends over a drink. Perfect.

Kevin and March 7 were left completely stunned.

"March, pinch me. Am I dreaming?"

March 7 smirked and twisted Kevin's waist hard.

"Hiss!!" Kevin winced. "That hurts! That hurts! That hurts!"

Now fully convinced he wasn't dreaming, Kevin looked around in disbelief.

"Is this real? Yuri, how did you do this?!"

Yuri clapped his hands together. "It's just one of the things I sell."

Store Cards were available in the system shop, though under a different name: Decoration Cards—each priced at 1,000 star coins.

Yuri then gave the train crew a tour of the store.

Himeko, observing the empty space next to the bar, considered moving the Spiritual Coffee Machine there.

The cabinet in the observation car is a bit cramped. If I put it here, it'll be much easier to use.

Meanwhile, Kevin and March 7 had wandered over to the small bar.

Kevin opened the refrigerator and was immediately shocked.

"March! Come look at this!"

March 7, who had been busy taking pictures with her Starry Sky Camera, ran over. "What is it?"

Kevin pointed inside. "Look! This fridge is huge!"

March 7 peered inside and gasped. "Whoa… this thing has a hidden storage space! It's at least 50 cubic meters!"

Himeko, Welt, and Dan Heng also happened to pass by and were equally amazed by the seemingly endless fridge capacity.

While the train crew explored, Yuri quietly communicated with his system.

"System, submit the task."

[Notification: Congratulations, Host! You have successfully opened your store!]

Rewards: Special Product Series (Elf Series unlocked), Invitation Letter for Guests from Another World x1.

A new set of tasks then appeared before him:

Task 1: Serve a total of 20 different customers.

Reward: Lottery Machine x1

Task 2: Reach a total turnover of 100,000 star coins.

Reward: Commander-Level Strength x1

Yuri smirked. This is going to be fun.

Yuri was just about to check the specific function of the Invitation Letter for Guests from Another World when Kevin suddenly peeked out from behind the sofa and patted him on the shoulder.

"Yuri!"

Yuri turned to see Kevin grinning, one hand on his shoulder and the other clutching the can of herring he had pulled from the scratch ticket earlier.

"Hey, Yuri, can I put something in your fridge?"

Without hesitation, Yuri nodded. "Sure, just don't put anything with a strong smell."

Kevin glanced at the can of herring. This should be fine… It doesn't smell as long as it's not opened.

With Yuri's permission, Kevin wasted no time, rushing to the fridge and placing the can into the storage space.

Then, he felt around his waist and pulled out a baseball bat.

He made a show of shoving it inside, but March 7 quickly stopped him. "Kevin, forget about the bat. Just find another place to put it."

Kevin thought for a moment and agreed. "Alright."

He looked around before propping the bat up near the door.

Meanwhile, Yuri was examining the Invitation Letter for Guests from Another World.

[Invitation Letter for Guests from Another World]

Effect: After use, you can invite a guest from another world.

The description was simple—just a single line—but that only made Yuri more curious.

Following the system's prompt, he took out the invitation and infused it with a bit of his own energy.

The next moment, the letter activated and vanished into thin air.

Teyvat Continent – Mondstadt, Eagle's Gate

Ying, the traveler from beyond the stars, and her floating companion, Paimon, were walking along the path, chatting.

"Ying, hurry up! We're almost at the Statue of The Seven!" Paimon called, flying ahead and waving enthusiastically.

Ying picked up her pace, keeping up with her tiny companion.

Just as they reached the top of a cliff, a strange sight appeared before them—an envelope with wings fluttering through the air, heading straight toward them.

Paimon tilted her head in confusion. "Huh? Ying, look at that! A flying letter?"

Ying raised an eyebrow and watched as the envelope gracefully landed in her hands.

Curious, she opened it.

The instant the seal was broken, a glowing portal appeared before them, startling Paimon.

"W-Wha—?! What is this?!"

Ying instinctively drew her sword, eyes locked on the mysterious portal.

Minutes passed. No one emerged from the other side.

Cautiously, Ying approached the portal, curiosity and wariness in equal measure.

"Be careful, Ying!" Paimon whispered anxiously, floating close behind.

Ying nodded and slowly extended a hand toward the light.

The moment her fingers brushed against its glow—

A sudden force pulled her in.

"Ying!" Paimon shrieked as she watched her friend disappear into the portal. She hovered in panic, fists clenched. "What do I do, what do I do?!"

With a determined huff, she dove in after her.

Inside Yuri's Shop

March 7 stood beside the still-glowing portal, hands on her hips. "Yuri, when's this mystery guest going to show up? It's been a while, and nothing's happening."

Kevin leaned forward, squinting at the shimmering gateway. "Yeah, this might be a dud. Maybe it's just for decoration."

Himeko, Welt, and Dan Heng were also watching with interest.

The idea of someone arriving from another world was intriguing. They wanted to see what kind of person would step through.

Yuri, unfazed, sipped his tea. "Patience. It won't take long."

As if on cue, the portal flickered.

A soft hum filled the room.

Then—

A figure shot out of the portal at high speed.

Followed by another.

Before Kevin or March 7 could react, the two newcomers collided with them, sending them both tumbling to the ground.

"Oof!"

Dazed, Ying slowly opened her eyes. Her surroundings were unfamiliar. Where am I…?

A shop? And… a starry sky beyond the windows?

Wait—

A starry sky?!

Her mind jolted into awareness. She was no longer in Teyvat!

Before she could react further, a groan beneath her caught her attention.

"Ugh… Miss, could you, uh, get off me? You're kinda crushing me here."

Ying looked down to see March 7, pinned beneath her, coughing weakly.

Eyes widening, Ying scrambled to her feet. "S-Sorry! I didn't mean to!"

She quickly helped March 7 up. "Are you alright?"

March 7 brushed herself off, shaking her head. "I'm fine, I'm fine. Just didn't expect that to happen."

Kevin groaned, pushing himself up. "Ugh, did Paimon just tackle me?!"

On the nearby sofa, Paimon lay sprawled out, tiny limbs twitching. Her head spun in dizzy circles.

Kevin turned to Ying, curiosity flashing in his eyes. "Hey, what's your name?"

Still recovering from the shock, Ying composed herself and answered, "My name is Ying. I'm a traveler."

Kevin and March 7 exchanged glances before introducing themselves.

March 7 grinned. "I'm March 7, an unknown passenger on the Astral Express!"

Kevin puffed out his chest. "And I'm Kevin, the Galaxy Batman, famous across the universe!"

Ying blinked. "...The what?"

Before Kevin could elaborate, Yuri approached.

"Welcome, Ying," he said, his tone even. "This is my shop, and as you've probably guessed, you're no longer in Teyvat."

Ying turned to face him. "You're the one who invited me here?"

Kevin clapped Yuri on the shoulder. "Yep, he's the guy!"

Ying frowned slightly at the word "invite."

Invite? Was that what that was? Because to her, it felt more like she had been forcibly teleported against her will!

If she weren't currently in his domain, she might've thrown a punch.

Yuri noticed the displeasure in her expression and quickly asked the system for clarification.

A moment later, he understood.

Ah.

So that wasn't an invitation—it was basically kidnapping.

Smiling awkwardly, he cleared his throat and continued. "Ying, I brought you here to offer you the opportunity to shop."

"Shop?" Ying narrowed her eyes. "You brought me across dimensions just to sell me something?"

Yuri remained unfazed. "I sell things from countless worlds. There's nothing you can't buy here."

Ying still looked doubtful.

Seeing her hesitation, Yuri gestured toward the bar counter. "If you don't believe me, go see for yourself. Those touchscreens list all my products."

Then he added, "Oh, and I only accept Star Coins here. But if my guess is right, you should be able to exchange Primogems for them."

That caught Ying's attention.

If this is real… If this shop really does have items from different worlds…

She could find a way to regain her strength faster.

And if she grew stronger...she could find her brother...
