Yun Beiming walked to the center of the rock, took out his dagger, and carefully cut off large clusters of green plants growing inside, wrapped them in cloth, and put them in his sleeve.

"Let's go."

Xiao Jinyu looked at the strange things in Yun Beiming's hands but didn't say anything. He knew very little about medicine and these brightly colored plants.

Since His Highness Prince Ning took this green plant away, it must be of great use.

"Come, let's go outside. Follow me and don't touch the plants around us."

Xiao Jinyu nodded, then cautiously looked around at the colorful plants.

The sunlight was once again obscured by clouds, and the valley was shrouded in mist. Yun Beiming and Xiao Jinyu carefully passed through the crevices in the rocks, left the back mountain, and returned to Fushuang Palace.

Upon arriving at Fu Shuang Palace, Xiao Jinyu tried to pull off the handkerchief covering his face. The stuffy air was unbearable, and the thick fog made it hard for him to breathe.

Seeing Xiao Jinyu's actions, Yun Beiming quickly stopped him, "Wait a minute! You're quick on your feet, kid!"

Xiao Jinyu glanced at her and asked with a questioning look, "Your Highness Prince Ning, why is that?"

[We've already left the valley and returned to the palace, and there's no longer any poison gas here. Why can't we remove the veil from our faces?]

“We just came out of a valley shrouded in poisonous fog. This handkerchief has been contaminated with poisonous gas. Don’t touch it with your hands yet. Some of the poisonous substances will stick to your hands, and if you touch your ears or nose, you can easily get infected.”

Xiao Jinyu decided to listen to Yun Beiming's words, slowly lowered his hand from his face, and looked at Yun Beiming.

"let me."

Yun Beiming took out another handkerchief from his pocket and carefully removed the handkerchief from Xiao Jinyu's face.

"Thank you, Your Highness Prince Ning." Xiao Jinyu smiled at Yun Beiming.

"Nothing to thank me for," Yun Beiming replied with a smile to Xiao Jinyu.

Yun Beiming threw the handkerchiefs he had taken off into the brazier in the corner of the courtyard.

"Alright, let's go in." Yun Beiming and Xiao Jinyu walked towards the backyard.

Walking into the backyard, Yun Beiming knelt on the ground and took out the green plant wrapped in a handkerchief, placing it aside.

"Jinyu, go get me a medicine pot and a mortar and pestle. If you don't have those, a garlic press will do." Yun Beiming turned to ask Xiao Jinyu for help.

The herb needed to be crushed to extract its juice for the three soldiers lying on the ground, so he needed a tool similar to a garlic press to crush the herb.

"Okay, I'll go take a look right away." Upon hearing Yun Beiming's words, Xiao Jinyu immediately headed towards the Imperial Medical Bureau, which was closer to the bureau than Langyue Pavilion.

A moment later, Xiao Jinyu came in and handed her a stone medicine pot and a mortar and pestle.

Yun Beiming took the medicine pot and mortar and pestle.

After examining the three soldiers and confirming that there were no other external injuries, he crushed the large, lotus-shaped green plant and gave the juice to the soldiers.

"How long have these three soldiers been lying here?" Yun Beiming asked.

"It has been more than ten hours."

Yun Beiming nodded. "There must be poisonous gas in this courtyard. You go out first, and I'll use some medicine to fumigate it."

"Thank you, Your Highness Prince Ning."

Yun Beiming used what was available. He went to a side hall in Fushuang Palace, found several medicinal candles that were commonly used, and lit the incense candles made from powdered herbs such as Tianxiong, soapberry, and wormwood.

Instantly, the Fu Shuang Palace was filled with an unpleasant, strong smell of Chinese medicine.

A moment later, Xiao Jinyu walked in and smelled the odor. He frowned and covered his mouth and nose.

Yun Duoduo, who was lost in thought about the medicine box in the Fu Shuang Palace, smelled a familiar scent.

What does this taste like?

She closed her eyes and slowly analyzed the contents: Tianxiong, Zaojia, and Wuyi...

[Could someone be using medicinal fumigation?]

As a medical professional, she was extremely sensitive to this smell and would use similar disinfectants to disinfect every time she conducted an experiment last night.

Of course, in modern times they use more advanced instruments and equipment.

After about half an incense stick's time, the three soldiers lying on the ground in the backyard gradually woke up. After coughing up black blood, their complexion and lip color gradually returned to normal.

Seeing the soldiers on the ground awaken, Xiao Jinyu looked at Yun Beiming gratefully, "Thank you, Your Highness Prince Ning!"

[This young man from the Xiao family has already said thank you several times in such a short time!]

"Alright, I'll leave this to you. These little guards are all fine now. With a little more rest, Xiuxiu will be able to walk normally tomorrow."

"There is a lot of poisonous miasma in the back mountain, especially in spring and summer. When we went there just now, I noticed that all kinds of plants are growing in the back mountain during this season, especially some of the highly poisonous ones that you can't tell the difference at all."

"You'll have to be more careful from now on."

"Thank you, Your Highness Prince Ning. I will repay your kindness today in the future." Xiao Jinyu bowed. Such kindness and help were a rare warmth in his cold life.

"Don't mention it, it was just something I did easily!"

"There's nothing to thank me for. I'll be coming to Fushuang Palace often from now on. Speaking of which, I should thank you properly for protecting Duoduo's safety!"

"Alright, I'm going to check on my little niece now!"

Xiao Jinyu nodded and watched Yun Beiming leave.

...

Inside Fu Shuang Palace, the door creaked open.

The weather has been getting warmer lately. At noon or when the sun is shining brightly, Granny Liu will open the doors and windows to let the house air out.

However, the weather wasn't particularly good today; it was cloudy and looked like it was going to rain, so all the doors and windows were closed.

Yun Duoduo didn't even need to look up at the door; she knew from the smell that it was her medical master, the Third Imperial Uncle, Prince Yun Beiming Ning.

[It turns out the person fumigating the courtyard with medicine was the Third Prince.]

Could something have happened in the yard?

Yun Beiming looked at Yun Duoduo's big, puzzled eyes and saw her covering her nose with her delicate white hand, and he smiled.

“Duoduo, an assassin broke into your Fu Shuang Palace last night.”

Assassin? Yun Duoduo frowned. Could it be referring to her third brother, Yun Yishu?

[Hahaha, I can't laugh anymore! The sleepwalking third prince has been mistaken for an assassin!]

Jin Jinzhi raised an eyebrow when she heard the word "assassin".

"They were a few guards under Brother Xiao Jinyu. Last night, while they were capturing the assassin, they accidentally entered the back mountain and were poisoned. The Imperial Uncle just gave them the antidote."

"I was worried that the poisonous gas would stay in the yard. You're still young, so I just did some fumigation!"

"After the fumigation is done, there will be no more toxic fumes."

Yun Beiming continued explaining to himself, while the maids around him simply laughed.
