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

It was nighttime, and before bedtime, Beitang Yan was quite annoyed as Qin Suiyou kept taking out all sorts of strange tin gadgets.

"How much stuff are you hiding in there?"

After Qin Suiyou adjusted the equipment and confirmed that there were no problems, he placed Chen Xiaodong's blood collection tube into the centrifuge and pressed the button to start it.

“A lot! Guess how much stuff can be stored in a space that's the size of three Ye capital cities?”

Realizing what was happening, Beitang Yan raised his hand in surprise and covered his mouth.

"So big! Did you run around with three cities in your arms, honey?"

"More or less, so you don't need to be too surprised by anything I take out in the future, because they are all my personal belongings."

Beitang Yan's eyes widened, and he continued excitedly, "So, can you just go in and disappear with a bang!"

Qin Suiyou recalled taking Beitang Yan out to play a few days ago. He saw a magician perform a magic trick where a person appeared out of nowhere, which piqued his interest. So he said, "I can go in, but I won't just disappear with a bang."

Qin Suiyou had expected Beitang Yan to say he wanted to go inside the space to take a look, but instead he heard him say, "Wife, if that's the case, can you bring the fighter jet with you? Can I take a look?"

Qin Suiyou sighed, realizing that this guy hadn't grasped the point at all.

"I already told you this afternoon that the technology is still in the experimental stage and it hasn't been fully built yet. How can I show it to you? Of course, if you really want to see it, I can draw a few pictures for you."

Beitang Yanyan chuckled and touched her nose, "I got so excited that I forgot."

After saying that, Beitang Yan picked up the book "Military Theory" that he hadn't finished reading that afternoon and said, "Wife, you continue with your work. I'll read. Call me if there's anything I can do."

After that, Beitang Yan fell silent, quietly focusing his attention on the thick book in his hands.

After the blood was centrifuged, several data checks were performed. By the time Qin Suiyou finished, it was almost midnight. Beitang Yan massaged him, looking distressed.

"Can't we do it tomorrow? You insist on doing it until late at night, and your eyes are all red."

Because he has maintained a regular schedule in recent years, Qin Suiyou has not deliberately been strict with himself. So when he stays up late to work like today, even though he is in good health, his physical reactions are still quite obvious, such as the red blood vessels in his eyes that Beitang Yan found distressing.

"It'll be easier tomorrow if we finish everything at once. Okay, okay, time to sleep. Goodnight."

He lay down next to Qin Suiyou, his gaze never leaving the person beside him, his clear eyes seemingly carrying an unreadable meaning.

Gazing at the person before him for a long time, Beitang Yan uttered a low "Goodnight" in the air, then the candlelight went out, and the bedchamber became quiet and peaceful.

……

At dawn, Beitang Yan and Du Ruo tried to cook a pot of rice porridge for Qin Suiyou. Because he had no experience, he always felt that he hadn't put in enough rice, so when Du Ruo wasn't looking, he put a large handful of rice into the earthenware pot.

By the time Du Ruo realized it, it was too late, which made the porridge too thick. However, the taste was fine. Qin Suiyou praised Beitang Yan with a smile and then ate some according to his appetite. Beitang Yan then finished the rest of the porridge with a satisfied look.

Looking at Beitang Yan, who was acting silly with joy, Chen Xiaodong could hardly recognize him. After accepting Beitang Yan's current persona, he couldn't help but feel a deep respect for Qin Suiyou.

Qin Suiyou handed Chen Xiaodong a handwritten report and said, "The test results are good, and the next step of treatment can proceed." Chen Xiaodong could read some words, but not many. However, this was enough for him to judge how obscure the contents of the report were. He couldn't understand any of the terms like "cells" or "platelets."

However, not understanding the words didn't stop Chen Xiaodong from being happy. After looking at the words for a while, he looked up and asked Qin Suiyou, "Did you write this?"

Qin Suiyou nodded. "That's right, I wrote it."

Upon hearing this, Chen Xiaodong immediately put the report in his hand aside as if it were a treasure, asking his master to keep it for him for a while. Uncle Ma had no objection to this and was even quite happy.

Afterwards, Qin Suiyou led Chen Xiaodong to a room that had been converted into his small pharmacy. There was a makeshift operating table inside. Since there was no professional dental treatment table, this one would do after some tidying up.

While having breakfast, Du Ruo tidied up the utensils Qin Suiyou had brought out, and disinfected them as needed. As soon as they entered the room, Qin Suiyou had Li Yuanyuan and Beitang Yan, who had come to observe, sit down on one side, and then had Chen Xiaodong lie down.

At first, Chen Xiaodong was a little hesitant. After all, he was still a servant, and he would never dare to lie down in front of his master in front of others. However, before Qin Suiyou could say anything, Beitang Yan, who was sitting to the side, gave him a look, and he shut up and obediently lay down on the operating table where his four legs had been sawed off.

Qin Suiyou sat on a high stool to the side, with Du Ruo standing beside him to assist him.

It wasn't the kind of surgery that required extremely high hygiene standards like Beitang Yan's. Qin Suiyou simply tied up his long hair and didn't wear a hat, but he still had to wear medical gloves and a mask. After he and Du Ruo put them on, the procedure officially began.

On the operating table, Chen Xiaodong felt like his mind was a complete mess. To be honest, even after a whole night, he still couldn't mentally prepare himself.

Anyone who has experienced tooth extraction knows how painful it is. When children are losing their baby teeth, the ones that are pulled out are usually the ones that are about to fall out, which can leave a huge psychological scar on a child. Not to mention the one he has now, which is painful but shows no sign of falling out at all.

"Masashi, Masashi, please don't tell me when you're going to do it, or I might not be able to resist jumping up and running away."

Qin Suiyou held up cleaning tools and gestured for Chen Xiaodong to open her mouth. Chen Xiaodong thought that we hadn't gotten to the main point yet, so she opened her mouth as instructed.

While operating the device, Qin Suiyou said, "I'll give you anesthesia, it won't hurt, don't worry."

At Qin Suiyou's prompting, Chen Xiaodong spat the water used to rinse her mouth into a prepared spittoon, then exclaimed in surprise, "Anesthetic? It really won't hurt?"

Qin Suiyou smiled but remained silent, then put a mouth gag into Chen Xiaodong's mouth.

Du Ruo handed over a syringe already filled with anesthetic, which Qin Suiyou held in his hand, giving him a heads-up.

"It will hurt a little when the anesthetic is injected, just bear with it, Ayan will hold him down."

While Chen Xiaodong was still thinking, 'It's just a needle, why would anyone need to hold him down?' a sharp pain spread through his mouth.

"Um!!!"
