Whether Zhao Xiaocui was satisfied with the final fifty taels of gold or not, Qin Su didn't care. Her repeated provocations of Qin Su's bottom line were enough to annoy her.

Compared to Zhao Xiaocui, she is now more concerned about Yu Shuo. She has invited the best doctors in Shacheng, but the results are not satisfactory.

The doctor only said that Yu Shuo had been poisoned and had also suffered a head injury from falling from a height, which affected his intelligence and memory. Apart from that, his injuries had mostly healed.

To fully recover, it requires gradual conditioning, but the doctor didn't say how long that conditioning would take.

Qin Su didn't mind that Yu Shuo had become like this, but it was truly a painful thing for him to become like this when he was so proud and so talented.

"Should this matter be reported back to the capital?" Chongyang's gaze never left his master; he still couldn't accept it since they brought him back.

I can't accept that my master has become like this.

Such a big thing should be reported back, right?

Qin Su handed the pastries to Yu Shuo, who sweetly said, "Thank you, my dear wife."

Even though his mind had reverted to that of a child, he remained very polite, which left Qin Su with indescribable feelings.

"Let's keep it a secret for now."

Both Emperor Mingyang and the Empress Dowager doted on Yu Shuo. If they heard about this, they would probably send someone to bring Yu Shuo back immediately.

But they haven't finished dealing with things in Shacheng yet.

Qin Su told Lian Tao and Chongyang to leave first, and then closed the door behind them. Qin Su used a handkerchief to wipe the crumbs from Yu Shuo's mouth, saying, "I remember Ziyu doesn't seem to like sweets."

Yu Shuo shook his head. "I like them. As long as they're not too sweet, I like them. But who is Ziyu?"

His wife's sister asked him, "Are you talking about him? When did he get such a name?"

It sounds pretty good.

Qin Su was stunned for a moment, but quickly realized what was happening.

Ziyu was Yu Shuo's courtesy name. Generally, men would take a courtesy name after reaching adulthood. The royal family was different; they might take a courtesy name earlier. This was the case for both Yu Shuo and Emperor Mingyang, except for a few princes born out of wedlock.

"Ziyu is your courtesy name." Qin Su didn't choose to hide it from Yu Shuo. She took his hand, which was a little sticky because of the sweets. She led him to the mirror and pointed at Yu Shuo in the mirror, saying, "Have you noticed that you are different from how I remember you?"

Yu Shuo looked in the mirror.

The mirrors in the inn weren't very good; you could only vaguely see a person's face and general outline.

The man in the mirror had changed out of his coarse linen clothes and was now wearing a long, loose black robe, the fabric of which was crisp but not rough.

"I've grown up?" Yu Shuo stared at the person in the mirror, finding it increasingly strange.

"But when did I grow up?"

He couldn't understand it.

I clearly remember myself as only four or five years old.

He should have chubby little hands and be quite short at four or five years old.

It must be said that the head injury not only affected Yu Shuo's memory, but also had some impact on his intelligence, not just a matter of returning to childhood.

If Yu Shuo were only five years old, he should have noticed something was wrong much earlier, instead of waiting until now.

"Getting married and having children is something that happens after I grow up. So, have I lost a part of my memory, sister-in-law?" He turned to look at Qin Su, and only then did he realize that he had to look down at his sister-in-law because she was shorter than him.

Qin Su is considered tall for a woman, but she is still much shorter than Yu Shuo.

Yu Shuo reached out and touched the back of his head with his large, slender fingers. There was still some pain there, but it was much less than before.

"Is it because I injured my head?"

Qin Su nodded. "Yes. You've grown up now, you just came of age this year." She really wanted to tell Yu Shuo that he had a lovely and lively daughter, but he wasn't in the right state to know about it right now.

"sorry."

Yu Shuo lowered his head, looking very remorseful.

"Why did you suddenly apologize?" Qin Su asked him. She reassured him by taking his hand and sitting down, her tone gentler than ever before.

"I don't remember. I don't remember how I met you, or when we got together."

He thought it must be very important, right?

The Empress Dowager often talked about the days she spent with the Emperor, cherishing and finding them beautiful.

"It's okay, you'll remember. I'll help you remember."

Perhaps it was Qin Su's unwavering gaze that convinced Yu Shuo, who nodded emphatically.

"Okay, I'll listen to my wife's sister."

"Don't call your wife 'sister,' it's strange."

This is a really strange title, even though Yu Shuo is clearly a few years older than her.

"What's that called?"

"Call me 'sister'."

It's so sweet to just call her "sister"!

"elder sister!"

Qin Su's heart softened instantly, and she wished she could hug Yu Shuo and kiss him hard.

But looking into his eyes during the Spring Festival, Qin Su really couldn't bring herself to kiss him.

I feel a little guilty.

She originally wanted to ask about Prince Quegu, but... Yu Shuo was in such a state that she probably wouldn't get any information out of him. She could only wait until Chongyang brought back the other secret guards before asking them in detail.

"Sister, does my brother have a child now?" His eyes sparkled with anticipation.

"Yes, there are two princes, both quite young." And neither of them were born to the Empress, because the Empress Dowager was furious about it back then.

In the words of the Empress Dowager, the legal wife didn't even have a child yet, but the mistress was already pregnant.

At first, she didn't quite understand the meaning of "mistress," but after thinking about it, she understood.

They were referring to the imperial concubines.

"Can I play with them?"

Qin Su blinked.

Was Yu Shuo like this when he was a child?

No, the Empress Dowager mentioned that Yu Shuo was quiet as a child and had a mature and old-fashioned demeanor.

Qin Su wanted to pat his head, but realized that he was taller than her, and that he was her husband, not her real brother.

She awkwardly withdrew her hand, but unexpectedly, Yu Shuo seemed to know something, and obediently lowered his head, resting his head against Qin Su's palm.

"My mother also likes to touch my head. But I don't want her to touch it. I'm an adult now, and adults can't rely on their mothers."

"But my sister is my wife, so it's different."

He nuzzled against her, instantly making Qin Su submit.

In the evening, the guards followed the clues from the daytime events to the inn, where they were handed over to Chongyang and quickly led to Qin Su.

They were accompanied by a teenager with healthy wheat-colored skin, several small braids on his head, and a necklace hanging from his chest that resembled the teeth of some kind of animal, dressed in a foreign style.

Is this the prince of Quegu?

Qin Su looked him up and down, and had some guesses in his mind.

"Your Highness!" the guards shouted in unison, their voices not loud, but their presence was imposing.

Qin Su nodded slightly. Seeing their anxious expressions and the restless look in their eyes, she knew what was going on.
