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

After thanking him, Chu Huan disregarded the poison he had been poisoned and asked, somewhat excitedly, "How did you come up with this idea?"

Seeing Chu Huan's excited expression, Qin Suiyou tentatively asked, "What's wrong? Is something amiss?"

"No, no, that's absolutely right! Absolutely wonderful! Cough cough, cough cough..."

Chu Huan finished speaking very quickly, and without paying attention to suppressing his cough, a metallic taste rose in his throat, causing him to cough involuntarily.

Realizing he couldn't control himself, Chu Huan turned his head away and covered his mouth. After the coughing subsided, he noticed a red mark on his palm and discreetly put his hand behind his back.

"I apologize for my rudeness, Young Master Qin."

"Ugh."

Under Chu Huan's questioning gaze, Qin Suiyou shook his head.

"You're coughing up blood, aren't you? The doctor's right here, what are you going to do, hold it in?"

Chu Huan pursed his lips awkwardly, rubbing his fingertips together a few times in embarrassment.

"You still figured it out."

He then reached for his handkerchief to wipe himself, but Qin Suiyou stopped him.

"Wait a minute."

Then Qin Suiyou patted Beitang Yan, who was still unhappy after the yin-yang ritual, and said, "Give him a piece of alcohol wipe."

Reluctantly, Beitang Yan took out a box from his satchel, picked out the ugliest piece of cotton cloth in his eyes, and without even glancing at it, simply handed it to him.

Even if he hadn't guessed the identity of the person in front of him, Chu Huan wouldn't have felt anything, let alone if he had guessed it. While wiping his hands with the cotton cloth, he wondered why the Prince An's heir had changed so drastically.

After wiping his hands, Chu Huan still held the alcohol wipe in his hand. He raised his hand to his nose and sniffed it, then asked, "The alcohol wipe... is it soaked in alcohol?"

Qin Suiyou shook his head.

"It's alcohol, purer than regular wine, used only for disinfection. Drinking it is harmful to your health."

Chu Huan gestured to the satchel that Bei Tangyan was carrying and the alcohol wipes in his hand, and said, "Your things are quite special, very different from those of other doctors."

Beitang Yan: "Of course it's different. How can anyone else compare to him?"

Qin Suiyou didn't care about positive praise, but it wasn't good to put others down. He patted Beitang Yan's arm with a bit more force than before, signaling him to say less for now.

"The things I use are indeed different from those of other doctors, but as long as they work, that's fine. Alright, let's get back to the main topic. Since Young Master Chu insists on participating in the imperial examination, I will temporarily use acupuncture to suppress the poison in your body. I also need to make some preparations for the formal detoxification. We'll talk about it after you finish the exam."

Having said that, without further ado, Qin Suiyou took out his needle case. Just before he began, he asked, "Does Young Master Chu hold the brush with his left or right hand?"

Chu Huan replied, "My right hand."

Then, Qin Suiyou instructed Chu Huan to roll up his left sleeve to expose his entire arm.

"I need to draw some blood from you. The left side is the most suitable, but if you hold the pen with your left hand, I will still switch you to the right side. After all, the poisonous blood flowing through the veins of the arm will still have some effect."

Actually, when it comes to temporarily suppressing the poison that is mostly concentrated in the chest by bleeding, the simplest and most direct method is to do it directly in the chest, although the risk is greater. However, this is not a problem for Qin Suiyou. But thinking that Beitang Yan, who is jealous, is still by his side, he still has to sacrifice Chu Huan's arm to avoid trouble.

Just as they were about to take action, Qin Suiyou seemed to remember something and reminded Chu Huan, "You want to suppress the poison that is about to take effect now, instead of eliminating it. This will greatly deplete your vital energy. After you are truly detoxified, the recovery process will be much longer, and if you don't take good care of yourself, you will suffer from aftereffects."

Chu Huan didn't even frown, and calmly said, "I'm mentally prepared. With your help, I won't lose my life, will I?"

"Row."

Having confirmed the patient's firm resolve, Qin Suiyou also finalized the next course of treatment in his mind.

"I'm about to insert the needle. If you're afraid, Young Master Chu, you can close your eyes."

Chu Huan: "Please feel free to proceed."

Now it really began. Following a meridian, Qin Suiyou deftly inserted needles into Chu Huan's arm, showing none of the gentleness he had shown earlier when reminding people to close their eyes if they were afraid.

A short while later, the color of the meridian visibly darkened from top to bottom, and Chu Huan vaguely felt that his left arm seemed to become a little numb.

At this moment, Qin Suiyou quickly pricked two needles into Chu Huan's left thumb, and bright red blood beads instantly gushed out. But the next moment, the blood beads changed color, and as more and more blood gushed out, they gradually flowed down from Chu Huan's fingertip and dripped into a teacup lined with gauze that had been prepared beforehand.

Just as the blood droplets began to fall, Qin Suiyou inserted a silver needle into Chu Huan's shoulder. After a short while, Chu Huan vaguely felt that his arm was not so numb anymore, and the blood that had stopped dripping gradually returned to its normal color.

"Is this the end?"

Seeing that the blood had stopped flowing from his fingertips, Qin Suiyou removed all the silver needles from Chu Huan's arm.

"Doesn't it look simple?"

Chu Huan nodded honestly.

"On the surface, it seems to have some merit, but I don't understand the intricacies and dare not speak rashly."

Seeing that Beitang Yan had poured alcohol into the bottle used to soak the silver needles, Qin Suiyou put the silver needles into it.

"There are actually quite a few tricks to this, but it is simple for me. After all, it's not a real detoxification, but just a suppression. It's not that difficult, it's just that many people can't master it."

After the acupuncture was administered, the waiter served some of their signature dishes. The three of them ate lunch and then left Sanweixuan at different times.

Qin Suiyou and Beitang Yan left first. Before leaving, Qin Suiyou gave Chu Huan a small porcelain bottle.

"This is a recovery and replenishment pill. It also has some detoxification effects. Take one pill the night before the exam, and if you feel unwell during the exam, you can take another one. The proctor shouldn't care if you take medicine during the exam, right?"

Chu Huan shook his head.

"As long as it has been checked beforehand, it is allowed."

Qin Suiyou then reminded him, "You can't take more than two pills in the short term. I put three pills in there for you as a substitute. Too much of a good thing is bad."

Chu Huan nodded as he escorted the person to the door of the private room.

"Understood, will remember."

Upon exiting Sanweixuan, Chen Xiaodong and his carriage were already waiting not far away.

"Have you eaten yet?"

Upon seeing Qin Suiyou and the other person approaching, Chen Xiaodong nimbly jumped down from the platform.

"I've tried it. The food at Sanweixuan is really good, but it's still not as good as what Sister Du Ruo makes."

Because he had become familiar with several people in the Wutong Courtyard who often went out of the mansion to do errands, Chen Xiaodong would sneak off to the Wutong Courtyard when he had nothing to do at the mansion. After a while, he had become a member of the Wutong Courtyard. Chen Xiaodong was young and eloquent, and he always managed to get food from Du Ruo. If he hadn't been running around all day and was in the stage of growing up with high energy expenditure, he would definitely have gained a lot of weight.

Stepping onto the carriage bench that Chen Xiaodong had swiftly moved down, Qin Suiyou said, "If you want to flatter someone, you'll have to let them hear it when you get back."

After Qin Suiyou and Beitang Yan got on, Chen Xiaodong carried the bench up and jumped on himself.

"This isn't flattery, it's the truth."
