This time, she will definitely not let Qu Qingxi off the hook.

“Since I’ve said it, there must be evidence.” Ren Nuanyun sneered, then looked at the Crown Prince.

The Crown Prince nodded slightly and gestured to the Emperor. After receiving the Emperor's approval, he walked out of the Imperial Study and soon brought in a person. The person was wearing a gray robe and was carrying something in his hand, which was covered with a black cloth.

“Father, that night, when that person wasn’t paying attention, I sprinkled a kind of powder on him. The powder was colorless and odorless, and it was hard for people to detect. Once you came into contact with this powder, it would stay on your body for seven days. Even if you washed it with water, you couldn’t wash it off. However, there is a kind of butterfly that can smell the powder very clearly.”

"As long as this butterfly is released, it will smell the scent and land on the murderer." The crown prince glanced at Qu Qingxi with a look of certainty, as if he could already see the butterfly flying onto Qu Qingxi.

Qu Qingxi and He Liufeng exchanged a glance. He Liufeng stepped forward, turned to the Emperor, and said, “Your Majesty, I believe this method is not feasible. Butterflies are attracted by the fragrance of flowers, and women have always liked to use perfumes. This proves nothing.”

"Don't worry, Imperial Uncle, these butterflies will only be attracted to that kind of powder; other scents won't work." The Crown Prince seemed to have anticipated this question, and he immediately replied as soon as He Liufeng finished speaking.

"Then how can you prove that what you're saying is true? After all, we've never seen this kind of butterfly before," He Liufeng continued to ask.

"Uncle, I am the Crown Prince, and I have no need to lie." After being questioned and blocked by He Liufeng, the Crown Prince became visibly displeased.

However, He Liufeng is the Prince of Nanqing and the Crown Prince's uncle. He Liufeng has been suppressing the Crown Prince since childhood, and this is no exception. He Liufeng is not afraid of the Crown Prince at all.

“I am your royal uncle, and there is no need for me to lie. My queen has never done such a thing.” He Liufeng’s face was unusually cold, and his aura was full of unyielding authority.

The scene became tense. Qu Qingxi just stared at the scene before her without saying a word. The Emperor looked at Qu Qingxi frequently, wanting her to speak up and ease the awkward atmosphere. Qu Qingxi was He Liufeng's princess consort. As long as she spoke, He Liufeng's attitude would definitely soften.

Qu Qingxi would never do such a thing. He Liufeng was backing her up. She wasn't stupid; she wouldn't step forward to undermine him at this time and embarrass He Liufeng instead.

Qu Qingxi pretended not to notice the Emperor's hint, but stared straight at He Liufeng beside her with eyes full of admiration. To outsiders, it seemed as if Qu Qingxi was being completely controlled by He Liufeng, and that she was now completely focused on him.

He Liufeng naturally noticed the intense gaze beside him. He turned his head slightly and met Qu Qingxi's clear eyes. He Liufeng's heart skipped a beat.

Seeing that Qu Qingxi couldn't see his hints no matter what, the Emperor had no choice but to speak up himself, "In that case, Crown Prince, you must find a way to prove that this butterfly only recognizes the kind of medicinal fragrance you mentioned."

Both sides have their own version of events. Now, if the Crown Prince wants his words to be convincing, he must prove that his statement is correct.

Upon hearing this, the Crown Prince glanced at the Emperor in disbelief, then smiled bitterly to himself. His father had always doted on his younger brother, even more than his own children.

Ren Nuanyun stood beside the Crown Prince and quickly touched his sleeve. Anyway, the Crown Prince did indeed scatter the powder that night, and the system also told her that the person was Qu Qingxi. They would only win today. Since they insisted on proving it, then let them die more knowingly.

The prince nodded, glanced at Laifu beside him, and then walked directly to Laifu. "Eunuch Laifu, I apologize for the inconvenience." Before Laifu could react, the prince took out a small porcelain bottle from his pocket, pulled Laifu's arm, and gently poured a little into it.

Looking at the substance on Lai Fu's sleeve, the Crown Prince then looked at the Emperor. "Father, there is no fragrance on Lai Fu. I have already poured the powder on him. Father, you can have this person follow Eunuch Lai Fu to a place where there is no smell and check whether I am lying."

The Emperor gave the Crown Prince a deep look, then waved his hand to signal. Lai Fu nodded in understanding, turned around, and led the person who had just come in out.

The imperial study fell silent as everyone waited quietly for Laifu's answer.

Qu Qingxi and He Liufeng both knew that the butterfly was probably fine. They did this on purpose only because they couldn't stand the smug look on the face of the Crown Prince and Ren Nuanyun.

Sure enough, Laifu soon returned with the man, nodding to the Emperor and the Prince, "Your Majesty, Your Highness, this butterfly indeed only recognizes the powder in the Crown Prince's hand."

"Royal Uncle, Royal Aunt, can you believe me now?" The Crown Prince glanced coldly at the two people opposite him, then gestured for one of them to release the butterfly.

The man lifted the black cloth covering the cage, revealing an extremely exquisite cage. However, unlike ordinary cages, this cage had very small gaps, allowing one to clearly see something moving inside, but it was impossible to discern exactly what that thing was.

The man manipulated something under the cage, and the side of the cage opened, releasing a butterfly. The butterfly was entirely silver, with almost translucent wings adorned with delicate patterns. It fluttered and began to fly, the outside light shining in and scattering across its body, as if draping it in a layer of silvery shimmer—a truly beautiful sight.

Qu Qingxi stared curiously at the butterflies that were flying up. She had never seen butterflies like these before. They were so beautiful. She wished she could keep them as pets.

He Liufeng also noticed the look of amazement in Qu Qingxi's eyes and casually glanced at the butterflies.

The others stared intently at the butterflies that had flown out, wondering where they would end up.

Perhaps because they had just come out, the butterflies fluttered around in the air for a while, and then, as if they had a goal, they began to fly in two directions.

One direction is Laifu. It's understandable that the butterflies were attracted to Laifu's sleeves, which were just stained with medicinal powder.

The other direction was actually the Emperor!

This scene surprised not only the Crown Prince and Ren Nuanyun, but also He Liufeng and Qu Qingxi, who stared in astonishment at the butterflies flying towards the Emperor.

When Laifu saw that something was wrong, he quickly stood in front of the Emperor. No one knew what was going on with the butterfly. The Emperor was the supreme ruler, and if someone wanted to harm him, this was the perfect opportunity.

As the emperor watched the three butterflies hurtling straight toward him, his expression gradually turned cold. He stood up from his seat, pushed aside Lai Fu who was blocking his way, and with a flick of his sleeve, all the butterflies that had been fluttering about fell to the ground and died instantly.
