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

After finishing their business, Beitang Xinyue didn't stay long before taking her leave when Beitang Yan came over.

Before Beitang Yan could get close, Qin Suiyou stood up.

"Go and rest, today is another tiring day."

Beitang Yan readily agreed and followed, asking as they entered the bedroom, "What did she say to you?"

Qin Suiyou was feeling lazy at this point and didn't want to talk much, so he said, "It's just telling me some information in advance, it's nothing."

It seems he doesn't need to worry about it for now. Although his wife hadn't given him any trouble before, Beitang Yan still imagined it himself. He didn't insist on what it was, and after tidying up the thin blanket for Qin Suiyou and covering him with it, he lay down next to her. Sleeping in a rattan chair for too long isn't good, so Qin Suiyou would still take a nap on the couch. Beitang Yan also liked it most when his wife slept on the couch, so he could lie down next to her for half an hour.

In the afternoon, Qin Suiyou sorted out some medicinal herbs he had obtained from Li Yuanyuan, and after having Beitang Yan grind them, he took her to the small laboratory next to the study to teach her how to use some instruments.

Looking at the microscope that could magnify the medicine on the glass slide hundreds of times, Beitang Yan was so excited that he became like a real child, smiling foolishly and even whining that he wanted to look at it a little longer.

Qin Suiyou wanted to indulge him, but he still needed to observe the effects of the medicine he had prepared on the toxins that had not yet been cleared from Beitang Rui's body. If he let Beitang Yan play around for a while longer, the cells he had extracted from Beitang Rui's blood might lose their activity.

However, Beitang Yan was not idle. While Qin Suiyou was observing the situation, he was responsible for recording Qin Suiyou's observations in real time.

The two worked together very well, and their efficiency was quite high. When Qin Suiyou realized something was wrong and needed to adjust the dosage or change the herbs to improve the formula, Beitang Yan helped with the herbs. He was also very familiar with the tools Qin Suiyou had brought out, which greatly freed up Qin Suiyou's hands throughout the process. Basically, as long as Qin Suiyou said something, he would operate accordingly.

Having such a reliable and trouble-free assistant was truly getting Qin Suiyou excited. He almost got Beitang Yan to take a look at the reaction situation, but Beitang Yan couldn't do that yet. He hadn't studied cells in depth and couldn't analyze the reaction situation. This made Qin Suiyou think: Should he give Beitang Yan some crash courses soon?

Putting aside the matter of special treatment for now, Qin Suiyou participated in a pitch-pot competition at Princess Yong'an's flower-viewing banquet and won a large piece of Canaan incense. The reason for choosing it was that Qin Suiyou needed such an ingredient in the antidote he was making for the young prince Beitang Rui.

Before obtaining the piece of Canaan incense, Qin Suiyou studied the antidote formula, pondering whether there was anything that could be used as a substitute.

Because of the limited production of Canaan incense and the generally poor quality of what is available on the market, and because of the uncertainty of the dosage, Qin Suiyou needed as much as possible for his experiments, which temporarily stalled the pharmaceutical process. However, it was truly a blessing from heaven for Beitang Rui, a child who had suffered an undeserved misfortune in the womb, allowing Qin Suiyou to obtain such a lucky prize by chance.

Canaan incense played a significant role in this prescription; otherwise, it wouldn't have delayed Qin Suiyou's pharmaceutical preparation process. It was also a surprising ingredient, not only balancing the properties of several herbs but also stimulating their effects. This contradiction intrigued Qin Suiyou, leading him to conduct numerous experiments during the preparation process. However, he now restrained his inquisitive mind and focused on researching methods to improve detoxification efficiency while ensuring the medicine's gentleness and avoiding harm to the baby.

Improving detoxification efficiency is not too difficult; the challenge lies in not harming Beitang Rui's still young and fragile body, which cannot withstand strong medicine. After all, detoxification should be carried out as early as possible within a controllable range, which also increases the difficulty considerably.

As evening approached, Beitang Yan was diligently studying his notes. Qin Suiyou was engrossed in his studies, and having someone else help him would only disrupt his train of thought. Therefore, Beitang Yan obediently sat to the side, out of Qin Suiyou's way.

"All right!"

The voice, tinged with obvious laughter, made Beitang Yan also burst into a big laugh, feeling somewhat relieved. He looked at Qin Suiyou's unusually enthusiastic state and was a little worried that he would continue like this. Fortunately, it was over now.

Beitang Yan took the test tube containing the medicine from Qin Suiyou's hand and placed it on the test tube rack. Under Qin Suiyou's puzzled gaze, Beitang Yan pulled him to sit down and then gently massaged his pair of fair and slender hands.

"Rest for a while, and close your eyes too."

Qin Suiyou subconsciously did as he was told, blinked slowly, and then felt a pang of soreness.

"What time is it now?"

Beitang Yan continued massaging Qin Suiyou skillfully, then got up and massaged his shoulders.

"Just past the hour of You (5-7 PM)."

Qin Suiyou opened his eyes and said with a smile, "That's not bad. You completed the mission so quickly. I have a lot to thank you for today."

Beitang Yan ignored Qin Suiyou's praise and instead complained, "What do you mean by fast? You've been working on it from dawn till dusk, aren't you tired? It's not like we can't do it tomorrow."

Knowing that Beitang Yan's complaints were out of concern for him, Qin Suiyou did not refute them, but only said, "Isn't that all so that your lovely little brother can recover his health as soon as possible?"

"younger brother?"

Thinking back to the little guy Princess An brought over a few days ago, he was indeed cute and would even smile at her. He would probably be a good little brother in the future, but it wouldn't be good if he troubled his wife.

Beitang Yan's lips curled down, and he said with dissatisfaction, "There's no need to be in such a hurry. What if you get exhausted?"

Qin Suiyou felt a little dumbfounded.

"At this intensity, there's no need to get exhausted. People who are truly engrossed in research spend even short periods of time on a monthly basis. They don't even consider whether they'll get tired."

Upon hearing this, Beitang Yan asked nervously, "Then, wife, will you be able to study something for months at a time?"

Qin Suiyou shook his head and said self-deprecatingly, "No, I'm not a research fanatic, I'm very lazy."

Upon hearing this, Beitang Yan did not feel that Qin Suiyou was mocking himself at all, and even breathed a sigh of relief, saying, "It's better to be a little lazy."

Qin Suiyou chuckled softly, then said, "Alright, tidy up the table, I'm hungry."

Upon hearing Qin Suiyou say he was hungry, Beitang Yanyan immediately took action, without any hesitation, and finished in one go. After tidying up, she pointed to the test tube containing the medicine and asked, "Should we put this away?"

Qin Suiyou thought for a moment and then picked up the test tube.

"I'll keep it myself. I need to do a few more experiments to ensure stability, so it needs to be stored under specific conditions."

As he spoke, Qin Suiyou flicked his wrist, and his hand was empty.

Upon seeing this, Beitang Yan quickly turned his head left and right to look around. After finding nothing suspicious, he frowned and said, "Wife, you have to be more careful. You can't just do this outside."

"Understood, little steward."

"I'm not small, I'm very big."

"Yes, yes, you're the oldest."

"But in my heart, my wife is still the most important."
