My reborn husband and son are thinking about how to kill me every day.

The servants arranged by Doctor Rui brought over some clothes. After changing his clothes, Lu Yinheng finally listened to Ji Yunshuang and lay down to rest.

Even though his body was utterly exhausted, he couldn't fall asleep. His mind kept replaying the events of the day.

Although today's events were thrilling, they also left him with many memories he wanted to cherish.

At this moment, Fu Weiyi, like Lu Yinheng, was also unable to sleep.

Ji Yunshuang took him to see a doctor, whose diagnosis was similar to what Ji Yunshuang had said before. The doctor said that his amnesia was caused by an injury to his head.

As for whether he can recover his memory, the doctor couldn't say for sure; he could only try acupuncture first.

He had high hopes before the acupuncture treatment. But after the needles were inserted, he showed no sign of regaining his memory.

He couldn't help but feel anxious.

On the other hand, Ji Yunshuang found an opportunity to meet with Doctor Rui alone.

Upon seeing Dr. Rui, Ji Yunshuang went straight to the point and asked, "Dr. Rui, what did you find out?"

Fu Weiyi thought everything was under his watchful eye and control, but little did he know that Ji Yunshuang and Rui Bingtian had already subtly completed their exchange without him noticing.

It must be said that Rui Bingtian truly deserves his position as a physician in the Prince's Palace; his abilities in all aspects are first-rate.

In such a short time, he completely understood Ji Yunshuang's meaning.

Upon hearing Ji Yunshuang's words, Rui Bingtian said, "He was indeed disguised. I removed the disguise from his face while I was giving him acupuncture."

There are no mirrors in this room, and since he has lost his memory, he shouldn't discover that he has revealed his true face.

The acupuncture points he used on him were not the points for restoring memory, but rather points for putting him into a deep sleep without warning.

Because it wasn't a sudden, sudden fall into a deep sleep, but rather a slow, gradual process, even the usually very alert Fu Weiyi didn't notice anything amiss.

He thought the doctor was really treating him.

Rui Bingtian waited until he fell into a deep sleep before carefully examining his face and uncovering the disguise on his face.

Ji Yunshuang said, "What kind of disguise technique did he use? How come I didn't notice anything before?"

Rui Bingtian took out something as thin as a cicada's wing and handed it to Ji Yunshuang, saying, "This is a lost art in the martial arts world, the Human Skin Disguise Technique. This thing has been soaked in medicinal juice and can be worn on the face for a long time."

Upon hearing that it was human skin, Ji Yunshuang felt a chill run down her spine and was even less inclined to touch it.

This reminded her of people whose flesh and blood had been eaten away by insects, leaving only a shell.

Seeing Ji Yunshuang's expression, Rui Bingtian smiled and said, "Don't want it? If you don't want it, I'll just keep it."

Ji Yunshuang shook her head, "If you want it, then keep it! But this thing is incredibly dirty, don't you find it disgusting?"

Rui Bingtian said with a smile, "The medicine soaked in this is no ordinary medicine! When you were in contact with that kid before, did you never smell any medicine on him?"

"Also, you guys fell into the water earlier, right? That kid was in the water for so long, and you didn't see anything wrong with his face, did you?"

Upon hearing this, Ji Yunshuang became even more curious, "This is all thanks to the medicine."

“It accounts for half,” Rui Bingtian said. “Besides the medicine, the bone structure also needs to fit properly.”

As if afraid she wouldn't understand, he gestured with his hand to show the outline of his face, "The person whose skin has been peeled off must have the same facial features as the person in disguise in order to fit perfectly."

Thinking of the person whose face had been brutally stripped off, Ji Yunshuang felt a surge of anger and pity.

Just because a powerful person wants to disguise themselves and assume a different identity, does that mean another person has to have their face ripped off?

"Is the person whose face was peeled off still alive?"

Rui Bingtian frowned, a look of reluctance on his face, and said, "That's hard to say. As far as I know, peeling off the skin completely from one's face involves a lot of torture."

Special medicine must be given to the person first, and then a special knife technique combined with the medicine must be used to peel off the skin completely.

After enduring so much torment, few could survive... and even those who were lucky enough to live would likely be neither human nor ghost.

When it comes to the fate of those who were skinned alive, the joy of studying the precious medicine diminishes somewhat.

As a doctor, Rui Bingtian often deals with life and death and has seen many pitiful people who want to live but cannot.

He had long since developed a strong heart.

But at this moment, thinking about the fate of those who were skinned alive, he couldn't help but feel down.

Ji Yunshuang said, "Doctor Rui, didn't you say before that this kind of disguise technique was lost?"

"Because this disguise technique is cruel, the potions needed are very difficult to obtain, and skinning is not something that can be done successfully even with thorough preparation... In addition, this method is inhumane, so it was suppressed by righteous people, and then some people sought revenge, so it was gradually lost."

Rui Bingtian frowned as he examined the mask in his hand, saying, "I never expected that this long-lost art of disguise would still be used by someone. This person's identity must be quite extraordinary!"

Ji Yunshuang said, "The Crown Prince of Xuan is indeed not simple."

Rui Bingtian was visibly taken aback when Ji Yunshuang revealed the man's identity to him so readily.

"You're just telling me this? Aren't you afraid I'll tell others?"

Ji Yunshuang smiled and said, "Dr. Rui is one of us. I believe you can tell what to say and what not to say, so I don't need to worry about it."

Rui Bingtian was pleased by her words, "It's no wonder he's the Crown Prince of Xuan. Only people like them could gather so many talented individuals to revive this lost technique."

Although he has amnesia, you must still be careful, sir. A doctor who can concoct a skinning potion must also be a master poison maker; these people might already be loyal to the Crown Prince Xuan.”

"Thank you for the reminder, Dr. Rui." Ji Yunshuang said after thanking him, and stood up, saying, "Then I won't bother you any longer. Dr. Rui, please get some rest."

Rui Bingtian looked at the thin woman in front of him.

Although he knew that she was the only female official in the Great Zhou Dynasty who now ruled the entire Ningxing Prefecture, he couldn't help but treat her like a junior every time he saw her.

The girl was tall and thin, with a waist so small that he suspected a strong wind would break her. He found it hard to imagine such a delicate girl going into battle and fighting against the enemy.

He couldn't help but ask with concern, "Would you like me to check you over? I heard you also fell into the water today."

Ji Yunshuang met his kind and concerned gaze, her heart warmed, and she smiled and said, "No need, I checked myself before, I'm fine."

Rui Bingtian suddenly remembered that this lady was not only skilled in literature and martial arts, but also in medicine. Some of the prescriptions she produced were ones that even his master might not be able to write.

He felt a little ashamed, realizing that he always forgot about her abilities because of her appearance.
