In the package was a pile of dark things. A strong smell of medicine floated in the air and entered everyone's nose, so that everyone knew what was in front of them in an instant.

"Drug residue?" the weight of the medicine is prepared by someone, added with water and heat, carefully boiled, poured out soup medicine for the patient, and the rest is drug residue.

"The imperial doctor doesn't smell it." Yan Xiaoxi handed over the drug residue to the imperial doctor. She knew that the medical skills of the whole imperial hospital were not as good as her own. It was really not easy to smell the components of pearl powder in an empty bowl. It was easy for the Imperial doctor to distinguish the medicinal materials from the drug residue.

The imperial doctor looked at Yan Xiaoxi with appreciation and felt that she was the smartest woman he had ever seen. She was not only skilled in medicine, but also intelligent. It was the dress of the south water country that Lord Lin could marry such a princess. Unfortunately, the Prince did not have this blessing. Otherwise, the North moon country would be more prosperous in the future.

"There is pearl powder inside." after careful identification, the imperial doctor came to the same conclusion as Yan Xiaoxi.

"What if there is pearl powder? Princess Lin seems to be trying to cover up. It has nothing to do with this matter?" Gu Zetian continued.

"The prime minister is wrong. My imperial concubine has been answering your questions, like you proving that the princess is not the murderer." Yan Xiaoxi calmly replied, not overwhelmed by Gu Zetian's momentum.

Seeing this, beiboxi, who stood silent, finally reacted. He finally understood what Yan Xiaoxi wanted to express after a big circle.

Fortunately, she has excellent medical skills, otherwise she will really muddle through Gu Yuyao.

"What do you mean?" Gu Zetian frowned and asked suspiciously.

"Isn't it clear to ask the Crown Princess about this?" in a word, the people's attention was shifted to Gu Yuyao again.

Gu Yuyao's face was pale, and she was stunned. She didn't return to her mind for a long time. It was obvious that she didn't calm down. She didn't believe Yan Xiaoxi could see through her tight layout.

How is it possible that the foolproof plan, without any evidence, was easily reversed by her, and Gu Yuyao refused to accept it.

Why?

Why?

"Yan Xiaoxi, I don't believe it. You must be lying to me." Gu Yuyao was flustered and incoherent. She knew clearly that she would never have a chance to turn over once she lost this time.

"What's the princess nervous about?" Yan Xiaoxi deliberately didn't say the answer readily in order to wait for this moment.

Watching the prey struggling to death is a pleasure, which can be regarded as real revenge.

Gu Yuyao framed her three or two times. To be kind to the enemy is to be cruel to herself. This time, Yan Xiaoxi doesn't intend to let her go.

"I didn't." Gu Yuyao quickly denied.

Gu Zetian glared at Gu Yuyao and wanted to keep her calm. The sentence that blood is thicker than water didn't play any role in him. A piece that hasn't played a role was discarded. He felt it was a waste.

After so many years of layout, Gu Yuyao was placed on beiboxi and wanted her to help him find out the news. Unexpectedly, she fell in love with beiboxi and caused him a lot of trouble.

If he had known that he couldn't save her, Gu Zetian wouldn't have run into muddy water. Now that the matter is over, he has to take one step at a time.

Receiving Gu Zetian's eyes, Gu Yuyao breathed a sigh and thought that her father was the big backer. She didn't have to panic. With his power, even if she was exposed, she wouldn't do anything.

Yan Xiaoxi smiled and saw through Gu Yuyao's thoughts. He also understood that Gu Zetian's wishful thinking and the crime of murdering the queen was to kill his head. No matter how powerful Gu Zetian was, he could not protect Gu Yuyao.

Unless, for the sake of Gu Yuyao.

"It's been a long time. Is it time to reveal the answer?" the emperor thought it was time to give Gu Yuyao's father and daughter a fatal blow.

Yan Xiaoxi understood, nodded and replied, "the whole thing is very simple. It takes too much use of the princess to murder the imperial concubine. She gave her a bag of medicine powder to tell her fans. The medicine is actually pearl powder. The princess added the soup medicine is pearl powder, not heding red."

"No, where did the hedonghong in the medicine come from?" the doctor didn't want to blurt out.

"Hedinghong was made by the Crown Princess herself." Yan Xiaoxi replied.

Gu Yuyao felt terrible about Yan Xiaoxi's analysis. She seemed to have seen the whole process with her own eyes. She guessed that it was eight or nine to ten, which was related to her life. She still resisted tenaciously and retorted: "the crown prince sent someone to monitor me day and night. How can I go down heding red?"

That's right. Beiboxi personally admitted it. Gu Yuyao really didn't have a chance.

"Yes, still in full view of the public." this is Gu Yuyao's best place. No one thought she would poison in that way.

"How is it possible that everyone is watching, and no one is stopping me." Gu Yuyao tries to keep his voice calm.

"Because you put the heding red down in an instant. No one thought of it when everyone was unprepared." looking at the two people, you said a word and I said a word, and everyone was still confused.

The scene was full of discussion and fell into a noisy scene.

"Be quiet." North Percy made a gesture, and suddenly became silent. We could only hear each other's breathing.

At this time, a medicine boy whispered, "wasn't the princess who took the medicine at that time? She had relieved the medicine, as Princess Lin said..."

His voice is very small, but it is enough for everyone to hear in a silent environment.

"Shut up, master. It's your turn to interrupt." Gu Yuyao scolded.

"Why? Is the Crown Princess guilty?" Yan Xiaoxi asked with a smile.

"Princess Lin misunderstood. My concubine was just teaching a servant who didn't understand etiquette." Gu Yuyao looked like Gu Zetian asking for help, getting closer and closer to the truth. What should she do? “

"Really? Didn't the medicine boy explain the key problem of the whole thing?" the person who answered was North Percy, who had understood the whole process.

The medicine boy followed the imperial doctor to deliver the medicine. He personally handed the bowl full of soup medicine to Gu Yuyao, transferred it from Gu Yuyao's hand to him, and he fed the medicine to the queen.

If she had planned everything well, she would still have the opportunity to poison in an instant.

"Prince, what are you talking about?" Gu Yuyao pretended not to know and looked at beiboxi stupidly.

Beiboxi saw Gu Yuyao's true face and wouldn't be deceived by her disguise. He joked and replied, "the crown princess will continue to pretend to be stupid?"

"I didn't. It's really not me. Your highness, you should believe that Princess Lin framed me. It's none of my business." Gu Yuyao's dying resistance was particularly pitiful.

"That's enough. Whoever hurts the mother and empress, the crown prince will never let her go." beiboxi said this to Gu Zetian on purpose.

Gu Zetian glanced at beibaixi, looked at Yan Xiaoxi and asked, "Princess Lin still didn't show evidence, didn't she? Who knows if you colluded with the medicine boy?"
