Upon hearing this, Xiao Shengyuan was so angry he almost vomited blood.

"You wretched child, do you wish your own father were an executioner?!"

Xiao Qingyin didn't even glance at him.

Madam Xu was taken aback for a moment, then replied, "This old servant has never heard Madam mention any conspiracy, and is unaware of it."

Xiao Shengyuan snorted coldly.

She's honest, I suppose.

If she dares to frame him, he'll see how he deals with her.

Ms. Yao cried out that she was wronged.

"My lord, this old servant must have been bribed or threatened to spout nonsense here. You can't judge me based on just her side of the story!"

The Prefect of the Capital looked at Madam Xu: "Is there any physical evidence?"

Madam Xu shook her head: "The medicine we bought back then has all been used up by Madam, and the clothes Madam gave to Master have long been replaced and burned."

"I have some evidence here."

Xiao Qingyin presented the medical record that Ji Yunhua had just handed her to the Prefect of the Capital.

"This is the pulse record left by the old doctor of Qianjintang back then. The changes in Yun's pulse are consistent with the changes in her pulse after being poisoned by the strange poison 'Spring is Gone'."

If you do not understand, sir, you may send a doctor over.

"Spring has gone" has only become known to people in the last ten years; the old doctor probably didn't recognize it back then.

The Prefect of the Capital was not very familiar with these poisons from the martial arts world, so he first had a coroner identify them.

The coroner nodded: "It is indeed 'Spring is Gone'. This medicine can make people gradually weaken as soon as it comes into contact with the skin, and its effects are especially obvious on pregnant women."

Upon hearing this, Xiao Shengyuan immediately recalled the time when he was wearing the clothes given to him by Yao Shi, and he did indeed feel easily fatigued.

For several months, I felt powerless.

He only gradually recovered after marrying Yao.

At the time, he thought Yao was bringing him good fortune.

It turns out that even he was poisoned!

Xiao Shengyuan glared fiercely at Yao Shi.

Yao retorted, "My lord, even if Yun was indeed poisoned by Chun Qu Ye, it doesn't prove that I was the one who poisoned her."

"That makes sense."

The Prefect of the Capital looked at Xiao Qingyin.

"This case is insufficient to prove that Yao murdered Yun."

Xiao Qingyin asked Madam Yao, "May I ask if Madam has had any contact with Chun Qu?"

Without hesitation, Yao replied, "I've never even heard of it. How could a woman like me possibly come into contact with such a rare and powerful poison?"

"very good."

Xiao Qingyin smiled.

"Then I presume that Madam would not mind undergoing the examination."

Mrs. Yao frowned: "What kind of test?"

"Spring has a unique characteristic: anyone who comes into contact with it, regardless of the duration of contact, will have some residue in their body."

If these people take 'Falling Flowers and Flowing Water,' which is another kind of drug, their whole body will turn blue.

so……"

Xiao Qingyin gave a meaningful smile.

"I hope Madam wouldn't mind taking the medicine for testing."

Just as the coroner was about to say that he had never heard of it, he saw Xiao Qingyin give him a wink.

He immediately shut his mouth.

A hint of fear flashed across Yao's eyes.

There's actually such a medicine?

what to do?

Is there really no way to escape it?

She secretly glanced at Xiao Qingyin and noticed that her gaze wasn't so firm.

It seemed like feigned confidence.

A sudden flash of inspiration struck me.

Xiao Qingyin is bluffing her!

He immediately felt relieved.

"Try it then," Yao sneered, "but let me make this clear: if it doesn't turn blue, you'll have to kneel down and kowtow to me in apology!"

“No problem.” Xiao Qingyin smiled. “But if it turns blue, Madam will have to admit her guilt.”

Seeing that Xiao Qingyin was deliberately putting pressure on her, Yao felt even more relieved.

"Let's begin."

Xiao Qingyin nodded to Ji Yunhua.

Ji Yunhua handed over a medicine packet.

Xiao Qingyin opened the medicine packet, shook it a few times, and mixed the powder well.

He said to the Prefect of the Capital, "I would like to trouble you to find someone who has never been in contact with Chun Quye to take the medicine together as a comparison, so that no one will suspect that I have tampered with it."

Please rest assured, this medicine is not toxic at all. You can have the coroner examine it first.

"good."

The Prefect of the Capital had the coroner examine the medicine, which confirmed it was non-toxic. He then appointed a constable to take the medicine with Yao.

To avoid suspicion, the medicine was divided equally between the two people by the coroner.

After the two finished taking the medicine, Xiao Qingyin said, "It will probably take about fifteen minutes for the color to appear."

Yao sneered inwardly.

Let's see how this little bitch gets out of this mess.

She stood confidently in the hall, and when Xiao Shengyuan saw her, he began to doubt whether she had really been framed by Madam Xu.

As time went by, Yao's complexion became increasingly dark.

The onlookers exclaimed in surprise, "It's really starting to change color!"

Yao's heart skipped a beat.

No, no, this isn't real, it must be a stunt.

It was that little bitch who arranged it.

However, as more and more people began to clamor that "the sky has turned blue," Yao began to lose her composure.

"A quarter of an hour has passed. Please fetch a mirror, sir."

Xiao Qingyin smiled.

"So that my lady may know, you have indeed turned blue."

"You're lying to me!"

Yao pretended to be calm.

The constable's expression didn't change at all; how could she possibly turn blue?

After looking in the mirror, she could no longer maintain her composure.

In the mirror, her skin tone was bluish from head to neck.

Upon closer inspection, I noticed that the skin on both hands had turned blue as well.

With a clang, the bronze mirror fell to the ground.

Yao was filled with panic.

She suddenly rushed towards Xu's mother, grabbed her collar and said, "You put Chunqu on me too, didn't you?"

"I have always treated you well, why did you frame me like this! Why!"

"Madam, please confess your guilt, stop making excuses."
