Autumn has passed and winter has come; time has changed and the stars have shifted. Yun Duoduo is already three years old.

Sun Huohuo is almost six years old now, while Jin Zhuangzhuang is still a tiny child, only two years old.

For Yun Duoduo, three years old is a watershed moment. It is said that you can tell what a child will be like at the age of three. You can tell what a child will be like in the future from the age of three.

However, Yun Duoduo was different. She was originally the soul of a modern person, so her personality would not change much. However, the changes in her body brought her a particularly strong feeling. She seemed to feel that her physical strength had become stronger. Her arms and legs were much stronger, her ability to speak had improved a lot, and she even felt that her bones had become much stiffer.

It seems that even the people around me are treating me differently now.

Aunt Xiang treated me the same as always. Because I talked with Aunt Xiang the most on weekdays, Aunt Xiang had long been used to my precocious thinking.

But the nannies were different. Before Yun Duoduo turned three, the nannies who dressed her, combed her hair, and fed her mostly talked to themselves or simply didn't speak when facing her, because they felt that even if they spoke, the little princess probably wouldn't understand.

But now it's different. The nannies not only talk to her, but they also wait for her response.

What a wonderful change!

Yun Duoduo couldn't wait to grow up a bit more so she could visit the Shu Kingdom and experience the wonders of this world.

This world is so different for her. There are martial arts masters here, and some people can actually scale walls and walk on water. And she not only has the ability to hear other people's thoughts, but also has a magical medicine box.

All of this made her extremely excited.

...

On this day, the sky was clear and the air was crisp. Although the weather was a bit chilly, the charcoal fire inside the room burned brightly, so even though one was only wearing a nightgown, one would not feel cold in the bedroom.

Inside the Fu Shuang Palace, Yun Beiming teaches Yun Duoduo to recognize flowers and plants.

Yun Beiming placed a basket of dried flowers on the table. Yun Duoduo sat upright to one side, Sun Huohuo slumped on the table, and Jin Zhuangzhuang lay down to listen to the lesson.

"Duoduo, what is this?" Yun Beiming asked, pointing to a small pile of long, thin, cylindrical, beige dried goods.

“I know, I know, it’s honeysuckle!” Sun Huohuo answered quickly.

"Erhuo, this is Imperata cylindrica root, not honeysuckle," Yun Duoduo corrected.

The Imperata cylindrica root and honeysuckle flower look completely different. Erhuo, your memory is terrible!

[You're already six years old! In modern times, in another year or two, you'd be almost in first grade. Erhuo, with a memory like that, how are you going to learn Chinese, math, history, science, and English?!]

Fortunately, in ancient times, it was relatively simple. One could simply consult history books, straighten one's clothes, study the Analects, and memorize the Four Books and Five Classics, and that was it.

At that moment, Yun Duoduo could not have imagined that a month later, they would be assigned to the royal private school and suffer greatly there.

"Hmm, what can Imperata cylindrica be used to treat?" Yun Beiming asked patiently.

Yun Duoduo didn't speak. It wasn't that she didn't know, but the sound of her reciting her lessons echoed in her mind again—the sound of her reciting her lessons at the medical school.

The voice pulled her thoughts away.

"Imperata cylindrica root clears heat and detoxifies, and can be used for hematemesis, hematuria, urinary tract infections, edema, jaundice, difficulty urinating, feverish thirst, stomach heat vomiting, and cough," Yun Beiming explained when he saw that Yun Duoduo was silent.

"Yes, the weather is getting hot, and this Imperata cylindrica root can also be used to treat the heat rash you have," Yun Beiming continued.

"Yes, for treating heat rash."

"Third Imperial Uncle, Duoduo has remembered." Yun Duoduo replied earnestly; she already knew these things.

"What is this?" Yun Beiming picked up a handful of green plants.

“This is grass,” Sun Huohuo’s childish voice rang out.

"Damn? Hahaha!"

"What kind of grass is this!" Yun Beiming slapped his thigh and laughed heartily.

"Haha, that's right, this pile on the table is all grass."

"Erhu, you're always causing trouble here. This is purslane."

Purslane is an annual herb, entirely hairless.

The leaves are flat, thick, and serrated, dark green on the upper surface and light green or dark reddish on the lower surface.

Flowering period: May to August; fruiting period: June to September.

"Yes, the whole purslane plant is used for medicinal purposes. It has the effects of clearing heat and dampness, detoxifying and reducing swelling, anti-inflammatory, thirst quenching and diuresis; the seeds can improve eyesight; it can also be used as veterinary medicine and pesticide; the tender stems and leaves can be used as vegetables, they taste sour and are also very good feed."

Purslane can also be used to treat heat rash.

"good."

"Duoduo knows so much." Yun Beiming nodded approvingly.

"Uh, Aunt Xiang reads medical books to Duoduo before she goes to sleep, and Duoduo has memorized them." Yun Duoduo didn't think much about it and just blurted out what was in her mind.

Looking at the medicine on the table, Yun Duoduo thought of her medicine box.

When Yun Duoduo bought antivenom and procaine from the medicine box last time, she noticed that the medicine box had become more advanced and had more space inside. Moreover, medicines she had forgotten to buy, such as disinfectant alcohol and medical gloves, would be automatically provided by the medicine box as long as the money was paid.

The changes to the medicine box occurred after she had treated some people.

It seems that the more people she saves, the more advanced her first-aid kit becomes.

She wanted to help more people verify whether the pattern she had discovered was accurate.

Furthermore, she wasn't sure if the more people she saved, the more powerful the medicine box could be upgraded to; however, it seemed that she still needed to buy medicine with silver.

"Third Imperial Uncle, I want to treat the palace maids and eunuchs!" Yun Duoduo slowly expressed her thoughts, observing Yun Beiming's attitude.

Upon hearing Yun Duoduo's words, Yun Beiming was stunned. "What? Treat the palace maids and eunuchs? Does Duoduo want to emulate a physician who saves lives?"

Yunbei pondered for a moment. His little niece was indeed talented in medicine. She could treat common colds and rashes.

However, it seems somewhat inappropriate for a princess of a country to treat the palace maids.

However, at this moment, Yun Beiming was also undecided. After all, he had been staying in the Shu Kingdom for many years, and he was not very clear about the current rules in the Nanyang Imperial City.

"It might be feasible to treat the palace maids, depending on what the Emperor says. However, treating the eunuchs is not an option. Duoduo is still young, and especially when she reaches marriageable age, it might damage her reputation if word gets out."

Why does Duoduo want to treat the palace maids' illnesses?

Why did you want to treat the palace maids' illnesses?
