The legitimate daughter returns to the capital and embarks on a splendid life, tearing apart the fak

The physician's eyelids twitched suddenly, and he said urgently, "Your Highness, I'm telling the truth! I'm not lying!"

Xiao Jingyan didn't waste words with him.

He grabbed Doctor Du's right hand, and with a swift stroke, a section of his little finger fell to the ground.

Doctor Du was stunned for a moment, then opened his mouth wide and couldn't help but groan.

Xiao Jingyan picked at his ear, frowned, and said coldly, "Noisy. Too loud!"

The sound wasn't loud, but it was like a thunderclap, silencing the scream that Doctor Du was about to utter again.

The saying "the ten fingers are connected to the heart" is no exaggeration. The pain made his whole body convulse, but he dared not make a sound. He could only gasp for breath and dared not look at Xiao Jingyan.

Xiao Jingyan chuckled and asked again, "Now, can you tell the truth?"

"What I said...is...is the truth..." Doctor Du's teeth were chattering, but he still clenched his teeth and refused to let go.

Xiao Jingyan held up a finger and shook it, correcting him, "No, you're not telling the truth."

As soon as he finished speaking, he picked up the knife, grabbed Doctor Du's left wrist, and asked with a smile, though the smile didn't reach his eyes: "How about we cut this side too? To make it more symmetrical. I can't stand things being asymmetrical."

The physician, Du, was trembling all over, but he still gritted his teeth and said, "I... I really told the truth..."

Xiao Jingyan snorted coldly, his grip suddenly tightening, the blade pressing a shallow bloodstain into the base of his fingers: "Doctor Du, let me remind you, you just said that the Cold Jade Powder comes from the Southern Frontier. How did you find out about the Southern Frontier? What makes you so certain that it comes from there?"

He leaned down slightly, his voice low but clear, his tone firm, "You said you investigated the origins of the Cold Jade Powder. The reason you were able to find it is because you already knew about it, right?"

The physician's pupils suddenly contracted.

He was caught off guard by the questioning and blurted out the origin of the Cold Jade Powder. He never expected that the man in front of him would be so meticulous.

Yun Jin, standing beside her, also felt a twitch in her eyelids. Sure enough, she was no good at interrogation; if it were her, she definitely wouldn't have thought of these things.

On the other side, Physician Du was drenched in cold sweat, gritting his teeth as he stared at Xiao Jingyan, his heart filled with panic.

Xiao Jingyan straightened up, twirled the knife between his fingers, and said casually, "I just said I'd give you three chances. You've already wasted two. Now, I've lost my patience. You might as well just give up this hand!"

With that, he slashed the knife at Doctor Du's wrist. Doctor Du was so frightened that he pulled his hand back, but the blade still left a bloody mark on the back of his hand.

The physician of the Du family was truly devastated this time. Prince Yu's words were not empty threats; he really would take action.

He collapsed to the ground, his voice trembling like a leaf: "Your Highness... if I were to tell... they... they would not let me go... and the people behind Lady Liu... they would not let me go..."

"If you won't talk," Xiao Jingyan said calmly, "I can finish you off right now. Do you think the people behind you are more terrifying, or am I? Want to try? But this time, what I want is your head!"

Looking into Xiao Jingyan's cold eyes, Doctor Du finally understood that if he didn't speak, he wouldn't be able to leave this stone chamber today.

"I said..." Doctor Du finally resigned himself to his fate and lowered his head. "Your Highness is right. I did not tell the whole truth earlier."

I am not actually a pure Han Chinese. My mother is from southern Xinjiang, and my father is Han Chinese. My father was a merchant. He fell seriously ill while traveling in southern Xinjiang and was saved by my mother. Later, they fell in love, but my mother followed him back to the Central Plains and discovered that he already had a wife.

At that time, the child's mother was already pregnant. In a fit of anger, she ran back to the southern border, where the child was born. But from birth, the child was called a bastard. Later, when he grew up, he went to the Central Plains alone to find his father, and only then did he stay in the Central Plains.

Xiao Jingyan raised an eyebrow but did not interrupt him.

"As for the Cold Jade Powder used on Madam Yun... it is indeed a secret medicine from the Southern Frontier." Doctor Du closed his eyes, as if making a decision. "This medicine is not available in the capital, and very few people in the Central Plains recognize it. That medicine... was given to Lord Yun by Madam Liu."

Yun Jin blinked. The medical book in her mind didn't say where this medicine came from, only that it was extremely cold. She never expected it to be a secret medicine from the Southern Frontier.

Xiao Jingyan placed the small knife back on the table, turned around, looked at Physician Du, and asked, "You learned your medical skills from your mother, didn't you?"

The physician, surnamed Du, nodded without speaking.

Xiao Jingyan then asked, "Where is your father?"

The physician's eyes suddenly turned sinister, and he gritted his teeth, saying, "Dead!"

Xiao Jingyan asked with certainty, "You killed him?"

The physician from the Du family suddenly looked up at Xiao Jingyan, and after a long while, finally spoke, his tone full of resentment: "They deserved it! In the Southern Frontier, people called me a bastard, and when I returned to the Central Plains, his wife and son also called me a bastard! So I added something to their water and food, and they all died, hahaha, all of them died!"

The physician, Du, suddenly burst into wild laughter.

Xiao Jingyan looked at him calmly without interrupting.

Yun Jin felt a chill run down her spine. This man was so ruthless; he killed everyone just because she had insulted him a few times.

She suddenly realized that she was too kind and could never have imagined that human nature could be so ugly. If it weren't for Xiao Jingyan, she would never have thought of so much.

Only after Physician Du had finished laughing did Xiao Jingyan continue in a deep voice to ask, "How did you meet Liu Zhixue? What is her relationship with Southern Xinjiang?"

He spoke with such certainty that Yun Jin looked up in confusion, only to meet his sly smile. She immediately realized that he was just trying to trick Doctor Du.

The physician remained silent for a long while, his breathing rapid and disordered due to the pain from his severed finger. He endured the pain and slowly spoke:

"I met her in Jizhou. That year, I was practicing medicine in Jizhou and accidentally killed someone. But it really wasn't my fault; the person was already on their deathbed and there was nothing I could do. I didn't want to treat him, but his family forced me..."

Later, that man died, and they sued me. It was Lady Liu who helped me escape imprisonment.

Yun Jin frowned, puzzled, and asked, "Why would she help you?"

Doctor Du closed his eyes and resignedly replied, "When Madam Liu heard that I knew medical skills from the Southern Frontier, she came to find me. She said that as long as I was willing to do something for her, she could help me get out of prison."

Xiao Jingyan looked at him and suddenly said in a calm voice, "You're not being honest again!"

Doctor Du, unaware of what he had said wrong, looked blankly at Xiao Jingyan.

Yun Jin understood, and she reminded her, "How would Liu know you were in prison? You two probably already knew each other, right?"
