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

Qin Suiyou sighed helplessly in his heart.

It's unclear whether Xin Yue is genuinely naive or overly naive. He had previously told her that he came from a small, declining family in the south who had practiced medicine for generations. Given their background, it would be impossible for them to own a set of glass teaware. Yet, Bei Tang Xin Yue not only had no questions but also wanted to ask him where he bought it.

"Do you want to buy it?"

Hearing Beitang Xinyue ask that question, Qin Suiyou stopped thinking about it. In any case, for him, these things would gradually become things that didn't need to be hidden. However, he still needed to refine his words based on the lie he had told earlier.

However, if Beitang Xinyue really wants to buy this tea set from the craftsman who made it, it might be difficult in the short term.

"Hmm."

Beitang Xinyue nodded repeatedly, afraid that Qin Suiyou would not know her urgency.

"Well..."

"Is it difficult to answer?"

Beitang Xinyue looked at Qin Suiyou pitifully and pleadingly, her eyes brimming with tears that seemed about to fall, which was truly heartbreaking.

I hadn't realized before that Beitang Xinyue had such superb acting skills; her tears came so easily.

Qin Suiyou sighed and said, "It's not difficult, but you probably won't be able to find the craftsmen who make these things."

Beitang Xinyue tilted her head, puzzled, and asked, "Why?"

"These were bought from itinerant merchants in Zhongzhou City. They are unpredictable and not easy to meet."

"Zhongzhou City!"

After exclaiming in surprise, Beitang Xinyue murmured, "No wonder, that must be the only place where so many exceptional glass pieces can be made."

Qin Suiyou remained noncommittal. During his time in Yejing, he had heard various opinions about Zhongzhou City, most of which were highly praised, given that many good things had gradually flowed out of Zhongzhou City over the years.

Even though people born under the emperor's nose have more knowledge than people from other places, the people of Yejing City and even the entire Beiqian region still hold a sense of awe for things built based on the advanced ideas brought by Qin Suiyou. However, there are bound to be some people who think that the people in Zhongzhou City are deliberately creating mystique by taking advantage of the terrain. There are quite a few people like this.

Seeing Beitang Xinyue's reaction, Qin Suiyou asked, "How much do you know about Zhongzhou City?"

"Um……"

Beitang Xinyue pondered for a moment and said, "I don't know much. Most of it comes from rumors from some aristocratic scions, so it may not be very accurate. However, one thing is certain: Zhongzhou City is very mysterious. Some people even say that it is a fairyland. Otherwise, it would not be able to create so many rare and unique objects."

Beitang Xinyue's words were practically meaningless. Seeing the strange looks Qin Suiyou and Du Ruo were giving her, she probably realized that she had gone off-topic, so she tried to make amends.

“I remember that during the grand banquet for my grandfather’s birthday two years ago, a royal merchant presented a carriage that could move without being pulled by anyone. It was a rare sight in the world. It was said that he had bought it by chance from a traveling merchant in the Central Continent. Unfortunately, I caught a cold and stayed at the mansion during the birthday banquet and was unable to see it with my own eyes.”

"car?"

Qin Suiyou was somewhat puzzled. There were indeed cars in Zhongzhou City, but they were not allowed to be taken out.

His gaze shifted to Du Ruo, who shook her head slightly in confusion, clearly unaware of the situation as well.

Since he couldn't just go to the palace to investigate, Qin Suiyou put the matter aside for the time being and continued to listen to Beitang Xinyue's regretful sigh, wondering when she would be lucky enough to meet the traveling merchants from Zhongzhou.

Beitang Xinyue's visit was not only because she had nothing to do after leaving her younger brother, but also because she wanted to come to Wutong Courtyard for a free meal.

Du Ruo was a master chef. Before she arrived, the kitchen staff in Wutong Courtyard mainly took turns cooking for Jinzhu and Luoxian. The others not only didn't know how, but there were even kitchen "killers" among them. So the meals they made were basically unoriginal, and they were all made according to the standard, foolproof dishes taught by the cooks in the manor. Jinzhu and Luoxian were not bad cooks, but after a few days, even the foodie Lu Xi didn't have much of an appetite. However, he still ate until he was full as usual.

But things changed after Du Ruo arrived. Under Qin Suiyou's guidance, she was able to create many novel dishes, and she used a lot more seasonings than Beiqian did. After tasting her cooking once at Wutong Courtyard, Beitang Xinyue fell in love with her skills and wished she could live there so she could taste it every day.

After eating her fill, Beitang Xinyue stayed a while longer to finish Du Ruo's specially made digestive tea before reluctantly leaving. As she was leaving, Qin Suiyou said he would give her the glass tea set, which startled the girl so much that she quickly refused and ran out of the Wutong Courtyard without caring about her image.

"Young master, should we think of a way to go to the palace and take a look?"

After Beitang Xinyue left, Du Ruo asked with some concern.

Qin Suiyou shook his head, "No need. Even if they had the guts, they couldn't cross the Azure Sea. As for the car, if they weren't afraid to dismantle it, someone skilled in mechanical arts could have studied it thoroughly. It's not enough to make them do anything. There's no need to waste your energy on it."

After saying this, Qin Suiyou sighed and said, "But I still need to write a letter to my grandfather. If there really is someone with ulterior motives, it will be better to deal with it sooner rather than later."

Du Ruo was still somewhat worried, but thinking of Cang Qiong Hai and his consistent trust in Qin Suiyou, she felt a little relieved.

The days passed smoothly without any unexpected events, and two days later, Beitang Yan's medicinal bath ended.

"how?"

The day after the third medicinal bath, Prince An and Princess An also came to Yuqing Courtyard to watch Qin Suiyou check the results of the past few days for Beitang Yan.

"The results are very good. All the equipment I need is ready. After I give him two more acupuncture treatments, he will be able to have the surgery."

When Qin Suiyou performed the second Yuan-drawing technique on Beitang Yan, an unexpected yet reasonable problem arose.

During the acupuncture treatment, Qin Suiyou discovered that the power within Beitang Yan's body seemed to have developed an antibody, making the entire process extremely difficult and inefficient. Fortunately, with experience, the consumption of Qin Suiyou and Lu Xi did not change much and could be reduced slightly. Thus, Qin Suiyou had no choice but to decide to perform another Yuan-guiding technique on Beitang Yan.

"Operation……"

Princess An's face showed worry. She and Prince An had both heard Qin Suiyou explain the surgical procedure, and despite several days of mental preparation, they were still trembling with fear.

“Mother, Father, you must believe not only in me, but also in Beitang Yan.”

Princess An leaned against Prince An's arm and wiped away the tears that had involuntarily welled up in her eyes.

Seeing this, Prince An tightened his arm, thinking of giving his wife more support and comfort.

"Don't you understand Yan'er? He may not talk much, but he's a filial son. He won't let us, the white-haired, bury our black-haired son."

"What are you talking about?"

Princess An lightly punched Prince An in the chest and said, "He's so heartless. He went to the military camp without saying a word, and he didn't even discuss going to the Northern Region with us."

As she spoke, Princess An's tears fell like beads from a broken string.

Prince An remained silent. In these two matters, Beitang Yan was indeed too opinionated. At the time, Princess An thought that it was her father, General Zhenbei, who had led Beitang Yan into the military camp, and she was furious.

Qin Suiyou quietly waited for Princess An to gradually come to her senses under the comforting words of Prince An. After all, he had basically said everything he needed to say, and he didn't know much about what had happened before. At this moment, he couldn't help but think that it would be even better if that clever little girl, Beitang Xinyue, was present.

After the couple had thoroughly vented their anger by "criticizing" Beitang Yan's "glorious deeds," Princess An and Prince An exchanged a deep look for a while before Princess An looked at Qin Suiyou and slowly nodded, saying, "Child, just follow the original treatment plan. If there's anything missing, I'll arrange it myself."
