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

"Could my sister-in-law really be a goddess?"

Although it hadn't rained yet, Beitang Xinyue trusted Qin Suiyou's words completely and subconsciously began to let her thoughts wander.

"He only knows a little about astronomy. There's an Imperial Observatory in the palace, and the director there should be able to make calculations."

The Northern Qian Dynasty did indeed have an Astronomical Bureau, which was in charge of celestial phenomena and calculating the calendar. However, this aspect is not perfect at present. The complete twenty-four solar terms do not exist in this world, or rather, they have not yet been summarized. The seasons mentioned earlier were described from Qin Suiyou's perspective.

The Imperial Observatory was particularly important in this era that valued agriculture. After all, it is said that a skilled director of the observatory had predicted a severe drought in advance, allowing the people to prepare and reducing many disasters. Therefore, even though the officials in the observatory were not the highest-ranking, they were highly respected.

However, things were different for the Imperial Observatory under Beitang Xinyue.

"What are they? They're all a bunch of high-minded but incompetent fools. They're not even as good as a single hair on my sister-in-law's head."

Qin Suiyou was somewhat surprised, but he didn't say anything. He didn't know much about the Imperial Observatory of Beiqian, but for Beitang Xinyue, a girl who was occasionally spoiled but never arrogant, to say such a thing, there must be some hidden reason.

Without saying anything more about that, Qin Suiyou said, "When Rui Rui grows up a bit older and his body gets stronger, we'll be able to detoxify him. I'm going to collect some of his blood for experiments in a little while."

"experiment?"

"By extracting toxins from the blood, we can find the most suitable antidote in advance without affecting the little guy. This process of continuous trial and error is called experimentation."

Beitang Xinyue nodded and said, "I see. Following you, sister-in-law, has really broadened my horizons. I've even learned a new word."

Thinking of something, Qin Suiyou asked, "Why haven't I seen you going to school these past two days?"

Yejing has only one girls' school. Noble ladies from aristocratic families in the city, including the princess, all go there to study. This is because the most famous female teacher is not invited to the palace to teach the princess. Instead, she runs her own girls' school that accepts girls from ordinary families. The tuition is not high, but the rules are strict. Bullying or isolating classmates is not allowed. Otherwise, the girl will be expelled. Therefore, the aristocratic families in Yejing who love their daughters and want them to learn more will tell them to listen to their female teacher.

Beitang Xinyue also attended that girls' school. Because the girls' school was located on West Zheng Street, it was much more convenient than for the noble ladies outside the palace walls on North Zheng Street. However, in recent years, the emperor had no young princesses, and the princesses had no daughters. Beitang Xinyue was the only princess of her generation, and no one in the school had a higher rank than her.

"It seems that Master Liu has gone back to his hometown on some urgent business. There aren't many teachers in the school, and the other teachers can't spare the time. So, Yuqiong School has given us a short break, and we'll resume classes when Master Liu returns."

Qin Suiyou, somewhat puzzled by what he heard, asked, "Yuqiongshe?"

Beitang Xinyue was delighted to be able to tell her sister-in-law what she didn't know, and readily replied, "The girls' school is divided into three dormitories based on the level of knowledge: Yubei, Yuqiong, and Weirui. Each dormitory is further divided into two classes, A and B, corresponding to the process of a flower blooming. I am in Class A of Yuqiong dormitory. After passing the teacher's exam in a few months, I will be able to move up to Weirui dormitory."

Qin Suiyou praised, "Your Master Liu is truly ingenious; he must also be a lover of flowers."

Beitang Xinyue nodded hurriedly, "Yes, yes, yes, there's a whole patch of flowers outside our dorm that Master Liu planted himself, and they're blooming exceptionally well."

The baby in her arms started to whimper, and the experienced Granny Ye recognized the sound and said, "The baby is hungry."

Qin Suiyou carefully handed the baby to Granny Ye, and then called Jinzhu to lead Granny Ye and the wet nurse to the side room to breastfeed the baby.

Beitang Xinyue peeked into the side room and saw that Granny Ye and the others had gone there. She then turned to her and said, "His appetite has increased a lot these past two days. He groans from time to time. If it weren't for Granny's experience, Mother would have thought he was feeling unwell again, considering the previous situation."

Qin Suiyou inquired in detail about the frequency and approximate time of breastfeeding, and said, "After all, his body is gradually getting better, so his energy consumption is increasing. The current frequency is just right, and he will grow faster in the future."

"It's good that you grow up quickly. I've seen babies who were about the same age as Rui Rui before, but they were almost a whole size bigger than Rui Rui."

"Oh, right, I was just about to ask, does your sister-in-law like flowers? I'll take you to the girls' school sometime. Many families in Yejing want to pay the teacher to buy them, but the teacher is reluctant to part with them and they basically don't sell them."

Qin Suiyou nodded: "I like it quite a bit. I also know a little about cultivating flowers. Du Ruo and the others were helping me choose the new flower seeds I bought today in the yard. I saw that the yard was empty, so I thought I would grow some flowers to fill it out."

"Really!"

Beitang Xinyue stood up. "Sister-in-law, may I go and take a look? I didn't notice it when I passed by. I also want to learn. Although the teacher in the school teaches us, he is busy and only talks about it occasionally."

Which girl who loves beauty can resist pretty flowers? If she can, it's probably because she's allergic to pollen.

"of course can."

Once inside the courtyard, Beitang Xinyue soon raised a question.

“If you want to fill the empty space in the yard, why don’t you buy some mature plants that are already half-grown? It takes a long time to grow them from seeds.”

Beitang Xinyue was not the earliest student at the girls' school. When she started school, the area outside the schoolhouse was already full of flowers. However, Master Liu also cultivated new ones later, so she knew how long it would take to cultivate a flower from seed.

Just then, Qin Suiyou was called into the room by Lu Xi and didn't hear Beitang Xinyue's question, so Du Ruo answered it for him.

"Princess, you may not know this, but the young master's medical skills can not only save people, but also animals and plants. Correspondingly, the young master can formulate the most suitable fertilizer and nutrient medicine to accelerate the growth of flowers."

Wow! My sister-in-law (Jung-jun) is amazing.

Beitang Xinyue and her maids all sighed in admiration. None of them questioned these words. The fact that they could trust Qin Suiyou so much in just a few days made Du Ruo sigh in her heart once again at the exceptional personal charm of her young city lord.

"Sister Du Ruo, what exactly is it that Zhengjun can't do?"

Lan Ya, the youngest among those present besides Beitang Xinyue, blinked her round almond-shaped eyes and asked Du Ruo.

"Yeah yeah."

Others, including Beitang Xinyue, also looked at Du Ruo in agreement.

Despite being watched by six pairs of eyes, Du Ruo remained calm. She began to use Qin Suiyou's medical and cultivation techniques to gather some unusual events, embellish them, and then listen to the sharing of the people around her.

The group listened with great interest. After Zhu Yu and Lan Feng finished tidying up the extra stuff from the day, they also came over to help and listen to Qin Suiyou's story. Before they knew it, they had finished picking out all the flower seeds.
