The next day, the Fourth Prince indeed didn't get up, but slept with Lanqin until Chenshi (7-9 AM). However, he still couldn't sleep as well as Lanqin, so he called Nianxue in to help him change. Huanbi brought a copper basin to help the Fourth Prince wash his hands and face. Nianxue originally thought it should be Xicha who brought in the water, but why was it her again!

The Fourth Prince, of course, did not see through the thoughts of the two maids. He only instructed Nianxue, "Do not wake her. She had a fever all day yesterday and is weak. Let her sleep a little longer." Nianxue quickly agreed, and the Fourth Prince then said, "I promised to stay with her today. When she wakes up, send someone to the front yard to inform her."

After Fourth Master walked out, Nianxue walked up to Huanbi, who was tidying up her face towel, and said, "Where did Xicha go? When were you allowed to come into the inner room to serve her?"

Huanbi said nonchalantly, "Xicha should be preparing breakfast for the princess. I was just trying to help because I saw that you were too busy serving the master by yourself. Why do you misunderstand me like this?"

Nianxue stared at her for a while before scolding, "Go and help Zi Ranjiang wash the clothes. Don't go into the inner room without my permission!"

Huan Bi bowed slightly, then turned and left, but her face was full of resentment and unwillingness.

After the Fourth Prince returned to the front courtyard, Honghui and the other children learned yesterday that Lanqin had suddenly fallen ill. They wanted to come and visit her, but because of yesterday's situation, no one had time to greet them. Therefore, when Honghui greeted the Fourth Prince in the morning, he couldn't help but ask, "Father, how is Aunt Niu's health? Yesterday, the Third Prince and I heard that she had a fever. We wanted to go to the South Courtyard to visit her, but we were afraid that we wouldn't be able to help and would only cause trouble for Mother." It turned out that yesterday, when Honghui went to the main courtyard to rest, he overheard the Fujin (Prince's wife) and Granny Li talking about Lanqin's condition, which shocked him so much that he couldn't sleep.

"Your Aunt Niu is fine now, so you don't need to worry. It's just that she probably won't have time to play with you for a while. You can only visit her after she has recovered, understand?" Fourth Master was afraid that Lanqin would be unable to resist getting up and playing with Honghui and the others once they arrived because she didn't know her "condition," so he specifically instructed Honghui. However, he couldn't say it outright, so he could only say it in such a veiled way.

"Yes!" Honghui agreed, but he was a little puzzled. How could the fever be so serious? Judging from his father's words, Aunt Niu would probably need to rest for a long time.

After Honghui left, the Fourth Prince ordered Su Peisheng to bring breakfast, only to find Chunliu from the Fujin's quarters waiting outside the door, requesting an audience.

After Chunliu entered the Fourth Prince's study, she bowed properly and said, "The Princess Consort has sent me to invite the Fourth Prince to dine with her. Yesterday, the Princess Consort's younger sister, Yan Yu, came over, and the Princess Consort would like to invite the Master to meet her."

Fourth Master put down the door sticker in his hand and said, "Oh, it's Yan Yu. Come to think of it, it's been several years since I've seen her."

This Ulanara Yanyu is the half-sister of the Fujin (principal wife). She and Xinghui are siblings from the same mother, but she is much younger than the Fujin, only fifteen years old this year. The Fourth Prince had seen Yanyu when she was only about ten years old before, when he accompanied the Fujin to see Feiyanggu.

Therefore, after thinking for a while, the Fourth Master got up and went to the main courtyard with Chunliu.

"Sister, your brother-in-law actually spent the whole night with that little princess yesterday, and he even left from her place today?" Yan Yu was sitting next to the Fujin at the moment, watching her check the accounts of the household's various expenses, seemingly not having heard what she had just said at all.

"You're just a child, don't ask questions you shouldn't ask, understand?" The princess raised her hand, which was covered in red gold openwork nail guards, and tapped Yan Yu's forehead.

"Sister, I'm fifteen already, not a child anymore," Yan Yu said defiantly. Actually, she and Lan Qin were in the same batch of imperial concubines, though she had never met Lan Qin, and Lan Qin had never met her. Yan Yu was undeniably beautiful, but her performance in the selection was mediocre, and since being sent back to her family, she hadn't found a suitable in-law. Fei Yanggu had written to the Fujin (Prince's wife) several times, asking her to keep an eye out for a suitable family for her younger sister. A few days ago, the Fujin suddenly wrote back, inviting Yan Yu to stay at the manor for a while. And so, yesterday, Yan Yu, accompanied by her personal maid, entered the Fourth Prince's manor from Ula.

"Greetings, Your Majesty!" The greeting from outside interrupted Yan Yu's attempt to argue with the Fujin that she wasn't a child. She immediately stood up, rushed to the door, and looked outside. Behind Chunliu was none other than the Fourth Prince!

Yan Yu had not seen the Fourth Prince for many years. Now, when she suddenly saw him, he was no longer the taciturn and serious Fourth Prince she remembered from her childhood. The Fourth Prince looked more mature now, with some beard on his chin, and his eyebrows and eyes were more open and three-dimensional. He looked handsome and had a cold temperament.

"Yan Yu greets her brother-in-law!" Before the Fourth Master even came over, she stepped out the door and ran to greet him.

"Are you Yan Yu?" The Fourth Prince looked at the woman in front of him. Her bright smile and lively eyes were somewhat similar to the Fujin, but she was more beautiful.

"It is indeed Yan Yu!" Yan Yu walked up to the Fourth Prince, grabbed his sleeve, and pulled him towards the Princess's room. Looking at Yan Yu, the Fourth Prince couldn't help but recall the time he and his Princess returned to the Ulanara Mansion many years ago. He remembered that Fei Yanggu's youngest daughter was a clever and quick-witted girl, and he had enjoyed talking to little Yan Yu back then.

"Sister, brother-in-law is here! Can we have breakfast together now? Should we call the eldest prince over too?" Yan Yu exclaimed.

"Yan Yu, stop being so disrespectful. Quickly put down your brother-in-law's sleeve. You're all grown up now, and you still have no manners. What kind of behavior is this!" The Fujin scolded, then said to the Fourth Prince, "I'd like to bring Yan Yu to stay with us for a few days. Is that alright, Your Highness?"

The Fourth Prince glanced at his wife and thought to himself: Now that you've already taken her in, how can I possibly say no in front of Yan Yu? So, he said in a tone that barely betrayed his anger, "It's been a long time since I've seen Yan Yu. Stay a few more days."

“Alright, brother-in-law, then I’ll stay here. I’m so bored staying in the manor every day, the prince is nagging me to death.” Yan Yu was referring to Xing Hui. At this time, Fei Yanggu had already resigned from his official post, and his title had been inherited by his eldest son, Wu Ge. When Xing Hui received this result, although he was angry, the imperial decree had been issued, and he had no choice but to accept it.

"Chunliu, bring out the breakfast." The Fujin said to Chunliu, who was waiting at the door, while Yanyu had already pulled the Fourth Prince to sit down next to the Fujin.

"Brother-in-law, I heard there's a garden in your mansion. May I go for a stroll later?" Yan Yu asked, picking up the spoon placed in front of her.
