A crown princess who doesn't do infrastructure construction isn't a good doctor.

After Chu Yuning walked away, Qin Suiyou looked at Beitang Yan, who was reading a book, with curiosity in his eyes.

"How do you know so much?"

Beitang Yan retorted stubbornly, "I'm reading and can't be disturbed."

Qin Suiyou gently tapped the table, his tone soft.

"answer."

Beitang Yan immediately raised his head.

“I was there when you went to the doctor before. I just had to think about it for a second and I knew what was going on.”

Qin Suiyou rested his elbows on the table, propping his head up in front of Beitang Yan.

"I didn't realize you were so quick-witted."

Feeling looked down upon, Beitang Yan puffed out his cheeks.

"Of course it's a good idea. I'm not stupid. It's easy for me to figure out something this simple."

Qin Suiyou looked up, as if deep in thought.

"Well... why didn't you realize that you should be more tactful when talking to girls? As a boy, you should know how to be gentle and considerate towards women."

“I think she’s a bit slow, and I’m afraid she won’t understand if I’m being tactful.”

Then, remembering Qin Suiyou's words about cherishing women, Beitang Yan frowned.

"Why should I know how to be gentle and chivalrous? She has nothing to do with me. You are my wife. I cherish you and love you. Isn't that enough? To be gentle and chivalrous to others is the behavior of a scumbag. I am not a scumbag. What I want to do is to be a dutiful and loving husband."

"what?"

Now it was Qin Suiyou's turn to frown.

Beitang Yan knew what Qin Suiyou wanted to ask, and immediately betrayed his "accomplice".

"Lu Xi taught me, but I think he makes a lot of sense. As a qualified husband, I have to learn a lot. However, Lu Xi didn't tell me what he meant. I'm a little curious. Do you know what it means, wife?"

Qin Suiyou: "...You're still young, you don't need to know about this for now."

"You've made me sound so young again," Beitang Yan muttered quietly. "Yesterday you said I'm all grown up, why are you always contradicting yourself and giving me these excuses?"

Ignoring Beitang's subtle dissatisfaction, Qin Suiyou, thinking about the imperial physician coming the day after tomorrow, began to teach Beitang Yan how to feign illness.

In fact, Qin Suiyou could have simply drugged Beitang Yan, but thinking that he might not be willing, sure enough, when he told Beitang Yan about this method, he immediately shook his head in disagreement.

"Knocking you out isn't good. I won't know anything then, and what if someone bullies you?"

Qin Suiyou sighed in exasperation, realizing that Beitang Yan's reason for refusing was unexpected.

"Don't even mention that it's just a royal physician who came. Besides, I'm right here in the Prince's mansion, this is our territory. Who can bully me?"

Beitang Yan crossed his arms in protest, tilting his head and saying, "No way."

Seeing how resolute his attitude was, Qin Suiyou stopped pressuring him.

"It's fine if I don't drug you, but when the imperial physician takes your pulse, you can't show any resistance. You have to pretend to be unconscious in bed."

The thought of someone with ill intentions touching him made Beitang Yan feel uneasy.

Seeing his expression, Qin Suiyou seized the opportunity to press his advantage.

"If you can't accept it, I'll just drug you. That way, it won't be easy for me to give myself away."

"No, I can endure it for now!"

"you sure?"

"I am sure!"

Even so, Beitang Yan still sternly refused, leaving Qin Suiyou with no other option.

"Alright, then you'll start learning the rules for faking illness and feigning unconsciousness now..."

After a brief intensive training session, Beitang Yan, with his extraordinary learning talent, mastered most of how to convincingly feign illness and unconsciousness. The remaining small part was probably the possibility of Beitang Yan accidentally revealing his true identity when someone other than Qin Suiyou approached and touched him.

Qin Suiyou was already thinking about how to quickly and efficiently hypnotize and interfere with the imperial physician's memory if the physician noticed anything amiss.

It wasn't that Qin Suiyou didn't trust Beitang Yan, but rather that this guy could genuinely display his fussiness to the fullest extent given the right conditions.

For example, when it came to makeup, except for the first time when he was not familiar with the makeup tools, Du Ruo did his makeup. During that first time, Beitang Yan held up the mirror and watched the whole process, asking questions from time to time. In this way, he gradually mastered the technique of doing his own makeup. After that, he did his own makeup when he went out, and it was different every time.

Once he got the hang of it, Beitang Yan even tried to do Qin Suiyou's makeup as well, but Qin Suiyou wasn't interested and was too lazy to remove it, so he refused.

Getting back to the main point, Beitang Yan really is a shameless fussman who takes advantage of his childish nature. Apart from Qin Suiyou, no one can touch his things without his permission, let alone perform a direct physical act like taking his pulse.

After teaching Beitang Yan how to feign illness and unconsciousness, Qin Suiyou let him do whatever he wanted and began writing letters himself.

While writing the letter, Qin Suiyou asked Du Heng to light a stick of incense about the thickness of a thumb in the courtyard. Beitang Yan watched from the side, but could not smell any special scents other than the smell of burning wood around the lit incense.

"What kind of incense is this? Why does it have no scent?"

Du Heng: "The incense used to attract birds has a scent that only special birds, besides the righteous king, can smell."

Beitang Yan asked, "Why?"

Du Heng replied, "I don't know either."

Beitang Yan shook his head.

"So you're not that smart after all; you didn't even know this?"

Du Heng looked puzzled.

"Don't you know?"

Beitang Yan shook his head again, looking at Du Heng with an expression as if he were a fool.

"How could I possibly know?"

Du Heng: "..."

Then may I ask what your stance was when you spoke to me with that tone and that look in your eyes?

This was the first time Du Heng had encountered someone with such an eccentric way of thinking as Beitang Yan, and he couldn't reason with him. Du Heng felt that he should really reconsider this marriage proposal.

The incense was lit on both sides to attract the messenger birds. Should he write a letter back as well? No, no, if he writes a letter about this kind of thing rashly, the young city lord might be unhappy. Let's wait until next time. I need to discuss with Du Ruo how to write a letter back to Zhongzhou City next time.

Unaware that he had escaped being complained about to his father-in-law, Beitang Yan looked up at the sky, wanting to see what the birds attracted by the fragrance looked like.

As Qin Suiyou finished writing the letter and put it in the mailbox in the study, several pure white birds gradually flew over the Wutong Courtyard. Beitang Yan couldn't tell what kind of birds they were, so he just stared at them curiously.

The birds seemed to know their destination; after circling a few times, they flapped their wings and flew directly to the window of the study.

Qin Suiyou walked to the window with the letterbox in his hand, and also held a plate full of dried meat and grains in his other hand.

Qin Suiyou touched each of the white birds that were standing on the windowsill. They looked much larger than ordinary pigeons. He said, "Good children, you've taken good care of yourselves these days. Here, this is a reward for you. After you send the letter back, your mother will give you another reward."

When the white birds first saw the plate that Qin Suiyou brought, they did not immediately peck at the food on it. Only after Qin Suiyou said that it was okay to eat did they tiptoe to the edge of the plate and start eating.

Beitang Yan came over curiously, and Du Heng also went outside the window after extinguishing the incense.

Watching the white birds eating their treats and occasionally raising their heads to look around, their round heads looking very cute, Du Heng thought he should reach out and touch them like Qin Suiyou had done earlier. But before his hand could even get too close, one of the white birds turned its head, its round eyes staring unblinkingly at Du Heng's hand, its sharp beak tightly closed, ready to attack.

Knowing better than to touch the white bird, Du Heng withdrew his hand and sighed, watching it turn back to continue eating.

"Sigh~ I've fed them so many times, why aren't they affectionate towards me at all?"

Beitang Yan: "Maybe they just like good-looking people."

Du Heng: "!"

Qin Suiyou brought over a plate of water. After the white birds had eaten and drunk their fill, they leisurely stretched out their legs and let Qin Suiyou fix the letter tube on it.

Because there was a lot of content written, Qin Suiyou divided the letter into three parts and fixed them to the legs of three white birds. The birds that did not carry letters would act as guards during the delivery process.
