The most dissolute couple in the capital

His Highness Prince Liang was decisive and acted swiftly.

In order to fulfill his "dream of becoming a famous doctor", Cui Qingyi used some of her connections and spent a lot of money to invite a retired imperial physician named Qi, who had a strange temper.

This old imperial physician, Qi, worked in the Imperial Hospital his entire life. He was known for his fiery temper and unyielding integrity, and he even dared to disrespect the emperor.

Back then, he offended powerful figures when he was young, and it was only because the Cui family spoke up for him that he was spared punishment.

The first day of class was held in the study of the Prince's mansion.

Cui Qingyi specially had a soft couch set up next to her, euphemistically called "accompanying her in her studies".

Su Xin pondered as she helped her set out the tea and pastries.

Do accompanying parents to their children's studies have to eat this good?

The old imperial physician Qi was also helpless. He owed the Cui family a favor when he was young, and he never expected that he would have to repay it in this way in his old age.

I wish I hadn't acted impulsively when I was younger.

He brought a medicine chest to the Liang Prince's residence, wanting to check Liang Prince's basic knowledge.

He took a few dry grass roots from his medicine box and slammed them heavily on the table: "Your Highness, I don't care how noble your status is. If you want to learn medicine, you must start from the beginning. Tell me, what is this?"

Li Chengjing sat upright, staring at the pile of grass roots for a long time, then confidently pointed and said, "This is firewood!"

The study was deathly silent.

The old imperial physician Qi's beard trembled visibly. "This is astragalus! Astragalus that replenishes qi and strengthens the exterior! Is this what your firewood looks like?!"

Li Chengjing said, feeling wronged, "It looks exactly like firewood used in the kitchen. I've never cooked before, how could I tell the difference?"

The old imperial physician sighed, then pulled a dark, grimy object from his medicine chest: "And what about this?"

"I know how to do this one!" Li Chengjing's eyes lit up. "It's sheep dung!"

"This is Rehmannia glutinosa!!!" Imperial Physician Qi roared deafeningly, "Rotten wood! Utterly hopeless! Even if I risk my old life to confess my sins before the Emperor, I will never teach a good-for-nothing like you a spoiled brat!"

After saying that, the old imperial physician Qi flicked his sleeves and turned to leave.

I wish I could go back to that impulsive, young day and slap myself a few times.

"Hey, hey, hey, Elder Qi, please wait! Don't get angry, anger is bad for your health!" Cui Qingyi quickly spoke up to stop him.

The old man is not young anymore; we mustn't let him get so angry that he suffers a serious injury.

She winked at Su Xin beside her, and a maid immediately brought over a cup of calming tea.

Cui Qingyi said unhurriedly, "Old Qi, my prince hasn't memorized the 'Compendium of Materia Medica,' so he's naturally unfamiliar with these common herbs. If you test him on these, it's like asking a cook to forge a blacksmith. Why don't you try bringing some rare and exotic herbs?"

The old imperial physician Qi sneered and stopped in his tracks: "You can't even recognize common herbs, yet you talk about rare and exotic plants? It's utterly ridiculous!"

Despite saying that, the old man was a stickler for things. He took out several small, well-sealed porcelain bottles from the bottom of the medicine box and poured out some powder and a few withered flower petals.

"These are some rare medicinal herbs that I obtained during my travels in the Western Regions in my younger days. Some of them are so rare that even few people in the Imperial Medical Academy can recognize them all. If Your Highness can identify even one of them, I will take back what I just said!"

Li Chengjing pursed his lips, stepped forward, and lowered his head.

He first brought his nose close and gently sniffed twice.

His previously nonchalant expression suddenly changed slightly; he frowned and picked up a bit of powder with his fingertip.

"This yellow powder is styrax from the Western Regions, but the processing method is wrong. It's been overcooked, and it's also mixed with inferior agarwood chips." Li Chengjing clapped his hands in disgust. "If it's used to make lip rouge, it will definitely make people's lips peel and rot."

The cold smile on the face of the old imperial physician Qi froze instantly.

Li Chengjing didn't stop, and pointed to the few withered petals next to him: "These are the inner petals of the Tian Shan Snow Lotus. It's a good thing, but unfortunately it wasn't stored properly. It got damp and was exposed to the sun, so its medicinal properties have dissipated by 30%. If I'm not mistaken, there's also a very faint musky scent on it."

He raised his head, his gaze fixed intently on the old imperial physician, Qi: "Snow lotus is warm in nature. If mixed and ground with musk and applied to the skin, it will initially make the skin appear fair and radiant. However, within half a month, toxins will accumulate, causing stubborn dark spots. Old man, has your medicine box been contaminated with other smells?"

"You...how did you know that a mixture of snow lotus and musk has such toxicity?" The old imperial physician Qi's eyes widened, his voice stammering. "Such unorthodox pharmacology is rarely recorded in medical books!"

Li Chengjing shrugged matter-of-factly: "Nonsense! When I was young, I was making cosmetics, and I once used a mixture of snow lotus powder and musk, which caused a palace maid's face to turn black for half a month. I studied it for three days and three nights before I discovered that these two things were poisonous when mixed together. How could I not learn my lesson?"

The old imperial physician, Qi, was dumbfounded.

Cui Qingyi was stunned.

The old imperial physician Qi was impressed by the Prince of Liang's talent in medicine. He could accurately distinguish the origin, age, and processing errors of rare medicinal materials by smelling them, and even personally tested unorthodox pharmacological toxicities!

Cui Qingyi was amazed by Li Chengjing's audacity, thinking, "You really dare to try anything!"

"Incense making and pharmacology share a common origin..." the old imperial physician Qi murmured to himself, "With His Highness's talent, if properly guided, how could he not achieve great things!"

Li Chengjing was overjoyed: "Really? You're not kidding me?"

The old imperial physician Qi rose and bowed to the two: "In that case, I request that the Princess Consort supervise the Prince to ensure that he reads and memorizes the *Huangdi Neijing*, *Maijing*, *Shennong Bencao Jing*, *Shanghan Lun*, and *Nan Jing* daily..."

As the old imperial physician Qi continued reading through the medical records, Li Chengjing's face visibly grew darker and darker.

The old imperial physician Qi didn't pay attention. After giving instructions on some essential books, he continued, "I will come to the mansion every day to teach. Let's start by learning to identify medicinal herbs."

Cui Qingyi smiled as she saw the old imperial physician Qi out. When she returned, she saw Li Chengjing lying on the ground, his face ashen.

Cui Qingyi suppressed a laugh: "The number one divine doctor in Da Ning has a bright future ahead of him."

Li Chengjing was too embarrassed to show weakness in front of Cui Qingyi. He had already boasted about his medical skills, so how could he easily give up in front of the woman he loved?

He forced a smile: "Yes, yes!"
