Little Sizi came to my house and became the family's darling, and Li Shimin got anxious.

Li Yinxun followed Li Shimin slowly to the main hall, vaguely guessing that he probably wanted to ask about modern objects, but pretended to know nothing about it.

"Brother-in-law, why did you call me here specifically? Is there something you need me for?"

Li Shimin stood with his hands behind his back under the corridor, the hem of his dragon robe fluttering gently in the evening breeze.

He frowned slightly, his expression bearing the air of an emperor, and his lips moved twice before closing again.

It would be rather disrespectful for the Emperor of the Great Tang Dynasty to ask a maid for something.

After a moment's hesitation, he spoke casually.

"Xiao Xun, let me ask you, is that thing you call a cell phone expensive? Is it easy for ordinary people to buy?"

Upon hearing this, Li Yinxun instantly understood.

That's it?

After all that beating around the bush, all I really want is a cell phone.

For a dignified emperor to go through such a roundabout way just to get something, and to act so nonchalant, is truly awkward.

On the surface, however, he remained serious and replied in a seemingly innocent manner, "Brother-in-law, there are many kinds of mobile phones. Some cost tens of thousands of yuan, while others can be bought for a few hundred yuan. Everyone can afford one. It mainly depends on what configuration and model you want to buy."

Li Shimin's eyes flickered slightly, and he immediately pressed for an answer.

"In your opinion, if I were to buy one, which one would be the most suitable?"

Li Yinxun almost burst out laughing.

What does "if I want to buy" mean? Isn't that just wanting to buy?

She suppressed a laugh and said in a deliberately serious tone, "Then naturally I'll choose the three-fold one!"

"Three...folds?" Li Shimin didn't understand.

"It's the kind of screen that can be folded three times, making it easy to carry in your pocket. When unfolded, the screen is large and everything is clear. Most importantly, no matter how you fold it, it always looks good."

Upon hearing this, Li Shimin was speechless for a moment.

His lips twitched. Looking at Li Yinxun's serious and innocent expression, he didn't know how to respond. He had a feeling that the girl was teasing him, but he couldn't find any evidence to support it. He could only keep it to himself, his expression complicated and difficult to describe.

Empress Zhangsun could no longer hide it and slowly walked out, her eyes filled with an undisguised smile.

She heard their conversation clearly, and seeing Erlang's awkward expression, she couldn't help but feel annoyed.

She walked up to Li Yinxun with a gentle smile, getting straight to the point without beating around the bush.

"Xiao Xun, don't listen to your brother-in-law's riddles. My sister also wants a phone like that. I wonder if you could help me buy one? I'll pay for it."

Li Yinxun suddenly realized and slapped her thigh: "Hey, that's it! You should have said so earlier, sis. No problem, I'll take care of it! I'll go pick out the latest three-fold model later."

As she spoke, she glanced at Li Shimin, her eyes clearly saying: Just say you want it, why are you being so polite with me?

She had long since realized that Li Shimin wanted a cell phone, but she wouldn't tolerate his bad habit of wanting something but not saying it.

Li Shimin was embarrassed when his own empress exposed him and when Li Yinxun looked at him like that, so he coughed.

Empress Zhangsun smiled and shook her head, then called over a maid who was waiting not far away and whispered a few instructions to her.

Before long, a maid brought over a tray with several ingots of gleaming gold on it.

"Xiao Xun," Empress Zhangsun pushed the tray in front of Li Yinxun, "Here is fifty taels of gold, as a reward for asking you to buy the phone for me this time. You must accept it."

Li Yinxun's eyes widened instantly.

Fifty taels of gold! That's more than enough to buy a hundred top-of-the-line triple-fold phones!

"This...this is too much, sister!" Li Yinxun said, but her hands had already honestly taken the tray. It was heavy, and she was overjoyed. "Then I won't be polite! I promise to buy my brother-in-law the best!"

Li Shimin looked at the gold, said nothing, which was taken as tacit approval.

Empress Zhangsun straightened her expression slightly after the matter of the cell phone was settled.

"Xiao Xun, there's one more thing I'd like to ask you."

"Sister, you tell me."

"The hospitals over there... the kind of clinics that treated me," Empress Zhangsun carefully chose her words, "can they treat leg ailments? You mean... problems with the bones or meridians, the kind that make walking difficult and cause frequent pain."

Upon hearing this, Li Yinxun immediately understood.

This is a question about Crown Prince Li Chengqian's illness.

"Well," she didn't give a definitive answer, "we'll have to see for sure. We have all sorts of diagnostic machines there that can clearly see the bones and the internal condition. Some conditions can be treated, while others might only provide temporary relief. We'll have to bring the person over for a doctor's examination to determine the exact cause."

Li Shimin and Empress Zhangsun exchanged a glance.

They both saw hope in each other's eyes.

Empress Zhangsun took a deep breath and said directly, "To be honest, it's your nephew Chengqian. He had a serious illness a few years ago, and after recovering, he became somewhat lame, and it's getting worse over time. If possible, I'd like to take him to your place to have a doctor examine him. Whether or not it can be cured completely, it's still a hope."

Li Yinxun nodded slowly, her tone sincere: "Okay, sis, no problem, but..."

"Tell me if you have any concerns. Money is definitely not a problem."

During her few days in the modern world, she learned about the currency of that era on her phone. Gold and antiques could be exchanged for money, and the Tang Dynasty had gold mines.

Li Yinxun truthfully said, "Having money isn't enough; we need to solve the identity issue first. He's a grown man, but in the past, he didn't have a household registration or ID card, which made it quite difficult for him to see a doctor. I'll try to think of a way to see if I can help you register your household."

There shouldn't be any problems for the time being, but I'm afraid something unexpected might happen.

With the ID card sorted out, all worries are gone.

Upon hearing this, Empress Zhangsun knew that Li Yinxun had agreed, and a grateful expression appeared on her face: "Good, good, this matter is not urgent, we will discuss it at length. With your words, I feel much more at ease."

Li Shimin stood aside, silent.

Although he usually doted on Qingque, he never forgot about his eldest son, and it would be best if his leg ailment could be cured.

As they were talking, Li Yinxun took out her phone and casually turned on the screen.

The next second, her pupils contracted slightly.

The signal bars were clearly displayed at the top of the phone screen.

"How is this possible..." Li Yinxun muttered. Where would the Tang Dynasty get a base station?

Empress Zhangsun felt a pang of anxiety upon seeing her reaction.

"What's wrong? Did something happen?"

Li Yinxun did not reply immediately, but took a few quick steps forward with her phone in hand.

One step, two steps, three steps... ten steps.

The signal on the screen disappeared instantly, returning to a no-service state.

She stopped and went back to where she started.

The signal reappeared.

After several attempts, Li Yinxun finally figured out the pattern: within ten steps of the broken bowl, the mobile phone could receive modern signals; beyond ten steps, the signal disappeared.

What does this mean?

This means that the bowl is not only a medium for time travel, but also maintains a signal channel within a very small range between the two times.

She immediately told Empress Zhangsun about this discovery.

Empress Zhangsun listened with a solemn expression and silently kept it in mind.

Li Yinxun put her phone away and said to the two of them, "Sister, brother-in-law, I'm going back now. If you need to contact me urgently, just call me on my phone."

Li Shimin nodded: "Alright, go ahead. As for that girl, Sizi..."

Li Yinxun turned around and went out to find Sizi.

Not long after, he returned carrying the little princess.

The little princess clung tightly to Li Yinxun's neck, her short legs dangling back and forth, and she cried out in her childish voice that she wanted to go to the modern world with her auntie.

Li Shimin did not object.

Empress Zhangsun carefully instructed Sizi to be obedient and sensible, and not to be naughty and cause trouble for her aunt.

The little princess waved her hand at Li Shimin and Empress Zhangsun.

"Goodbye, Father and Mother! How many elbows are left?"
