The arrogant imperial concubine arrives, the favorite of the regent

Yun Mujiu had several guesses in his mind, one of which was that Du Ziheng's mental state might have become confused before he fainted.

Du Ziheng thought for a moment and immediately replied, "Princess, I am not ill, and I have no mental problems."

Ye Xiaohan then added: "Mu Mu, Du Ziheng has been under my command for six years, and there is nothing wrong with his body."

"Yes." Yun Mujiu nodded. "Du Ziheng is full of energy and spirit. His words and actions are usually decent. There should be nothing wrong with his brain."

Du Ziheng was a medical student, so he naturally understood what Yun Mujiu was thinking about. He was sure that except for the inexplicable headache he had felt when he was on duty at the pharmacy, he had never had any problems with his brain.

Yun Mujiu looked at Du Ziheng and advised, "If you have been wronged, you must clear your name if you have the chance. Even if you never return to Duti Valley, you are fighting for your life. If you don't insist on investigating further, won't it be a waste of money for those who have wrongly accused, mocked, and punished you?"

Du Ziheng's expression suddenly changed, as if Yun Mujiu's words had touched his heart.

Ye Xiaohan looked directly at Du Ziheng and added, "If your master were still alive, he would definitely help you find out the truth."

He looked away and said in a sad tone: "Life is not just about living, but also about fighting for one's life."

“If you don’t want to make trouble, you should just try to save face.” Yun Mujiu’s voice rose at the end, his tone full of encouragement.

Thinking of his master, Du Ziheng's eyes suddenly became red, and he tried hard to suppress the emotions in his eyes.

"Your Highness and Princess are right. The last time I returned to Duti Valley, I heard from other fellow disciples that Master had been looking for me for the past few years and had even investigated the truth for me. Before he died, he still regretted not clearing my name."

Du Ziheng's voice choked with sobs, and he completely opened his heart: "It's my fault. I thought I was disappointed with the people and things in Dudigu. It doesn't matter whether I go back or not, or whether I clear my grievances or not. In fact, it's my fault. It's important to find out the truth. I shouldn't be timid and cowardly in my heart."

Wei Song and Wei Bai smiled at each other, and patted Du Ziheng's shoulders together to express their encouragement to each other.

Yun Mujiu smiled, feeling relieved by Du Ziheng's determination. "By the way, Du Ziheng, come with me back to Qichiyuan later, and I'll give you a small physical examination first."

Du Ziheng asked curiously, "What kind of examination? You're not checking if there's anything wrong with my brain, are you?"

Wei Bai laughed heartily and winked at Du Ziheng, "Of course! I've long suspected that you are stupid and foolish sometimes!"

Du Ziheng was dissatisfied and retorted: "I am just being honest!"

...

At the door of Qichiyuan's pharmacy, Du Ziheng waited for a while.

"Squeak..." A big hole opened at the door of the medicine room, and Yun Mujiu stood at the threshold, "Come in."

Yun Mujiu had just taken out the relevant instruments from the doctor's system and placed them in the box in the medicine room in advance.

Du Ziheng walked in and followed Yun Mujiu obediently, occasionally looking at the layout of the house out of curiosity.

Yun Mujiu stopped in front of a table and picked up a piece of black cloth.

"I'll give you a brain examination. Don't worry, there won't be any problem. I don't doubt your IQ. I just want to check your brain fluctuations to prevent any hidden abnormalities in your brain."

Du Ziheng waved his hand, "Princess, you don't need to explain, I understand."

"Then I will blindfold you first, and I can only remove the tape after the examination is completed."

In fact, you don't need to blindfold yourself when doing an EEG, it's just that the electronic equipment required in the process is too new for people of this era.

Yun Mujiu didn't think she could find a reasonable reason to explain the source of these instruments, so she simply left everyone behind, leaving only her and Du Ziheng in the room, and blindfolded Du Ziheng. Du Ziheng couldn't see the machines, so he wouldn't have many doubts.

"Okay." Du Ziheng knew that Yun Mujiu had some unique instruments, and he didn't know how Yun Mujiu would examine him. Anyway, he believed in Yun Mujiu, and he would just do whatever Yun Mujiu said.

Du Ziheng sat on a wooden chair and covered his eyes with a cloth. Even though his eyes were still open, the cloth was thick and dark, and all he could see was darkness.

Yun Mujiu took a few steps, lifted the curtain and entered the inner room, then brought out a large wooden box.

Du Ziheng heard the sound of Yun Mujiu moving things and felt a little nervous.

Yun Mujiu put the equipment in place and comforted her, "It's okay. We'll just stick some clips on your scalp and we'll be able to get your brain wave information in a while."

"Yeah." Du Ziheng moved his body, which showed that he was still a little nervous.

Yun Mujiu said: "To explain briefly, brain waves are similar to pulse and heart rate. They just reflect certain aspects of the human body's physical condition."

Yun Mujiu's plain explanation was easy to understand, and Du Ziheng's sitting posture obviously relaxed.

Yun Mujiu quickly placed the electrode patch on a specific location on Du Ziheng's scalp and connected the other end of the electrode line to the EEG machine. After waiting for a while, Du Ziheng's EEG appeared on the EEG machine.

Not long after, Yun Mujiu quickly collected all the instruments and put them into a wooden box.

"You can untie the straps now."

Du Ziheng opened his eyes and said, "Thank you, Princess."

Yun Mujiu chuckled, "You are so polite."

Du Ziheng glanced at the wooden box on the ground unintentionally, and then looked away. He knew that Yun Mujiu had many special features, but Ye Xiaohan had specifically reminded him of this, so he had no intention of asking too many questions.

Yun Mujiu took the initiative to speak and told the results: "Your brain wave results are normal, there is nothing wrong with your brain. When you were guarding the pharmacy, you must have been stimulated by external factors and became dizzy and lost consciousness..."

Du Ziheng nodded, and the heavy stone in his heart fell a little.

Yun Mujiu sat down and picked up a medical book. "I've been reading medical books recently and encountered some things I don't understand. Can I ask you for advice?" She was reading medical books from this dynasty, and recently she was mostly reading the family medical books of Doctor Wu, so it was inevitable that she would encounter some new knowledge.

"I don't deserve it. My medical skills are limited. But as long as I know, I will tell you everything I know."

During the next incense stick of time, Yun Mujiu opened the medical book and asked questions, while Du Ziheng patiently explained and occasionally consulted Yun Mujiu with some questions.

After the two finished chatting, it was already dark outside the window.

After Du Ziheng said goodbye, Yun Mujiu got up to find Ye Xiaohan and told him the results of Du Ziheng's brain examination.

Ye Xiaohan said dimly: "I will assign some people to investigate what happened to Du Ziheng back then."

Yun Mujiu was a little worried. "Duti Valley is isolated from the outside world, and it's been a long time since the incident. It might be troublesome to find clues."

"It doesn't matter. As long as there are people there, there will be opportunities. Things will eventually come to light."

Ye Xiaohan still had an indifferent expression. Yun Mujiu thought that he had rarely seen Ye Xiaohan so flustered.

Yun Mujiu stood up and said, "It's getting late. Since I have applied medicine to the prince's wound, I will take my leave first. The prince should rest early."

"What?" Ye Xiaohan's brows showed a bit of anxiety, and he immediately refused: "No!"

"The prince said yesterday that he would stay with you for one more night. Tonight is a new night..."

Yun Mujiu didn't want to pay attention to Ye Xiaohan. She didn't want to embarrass herself by sleeping in front of Ye Xiaohan again. Besides, Ye Xiaohan was in the recovery period now, and it was not the right time for the two of them to be intimate with each other.

"Your Highness, please take care of yourself." Yun Mujiu blinked and left with small steps.

Ye Xiaohan frowned, looking at Yun Mujiu's departing back with some helplessness. It seemed that Yun Mujiu was still not close enough to him, and was so shy even to sleep in the same bed with him...
