If you want to find out who poisoned Zhao Ningyi, you must start from the source of the poison.

Maybe the other party wants to do it without being aware of it, or maybe only this suitable poison, so he chose sanhuazi afternoon poison. The layman may not know, but Luo qingluan, who is proficient in pharmacology, knows that the configuration of sanhuazi afternoon poison is very harsh. It needs three kinds of micro poisonous herbs with mutually exclusive properties, which can be successfully processed.

These three poisonous herbs do not specify which three must be. As long as they have the same attributes and have great toxicity, they are even sanhuazi afternoon poison. Therefore, ordinary doctors, even the imperial doctors in the palace, are often difficult to distinguish when they encounter this kind of poison. After all, there are too many herbs in the world. After mixing, they change their own attributes. It is difficult for 90% of doctors to distinguish the toxicity only, so that even if the imperial doctors in the palace were invited by the Royal Palace of Wuyang on the night of Zhao Ningyi's poisoning.

Now Luo qingluan has found out that Zhao Ningyi's sanhuaziwu poison is made of snake grass, lantern ember and ghost needle flower.

She couldn't help but rejoice that if the other party didn't choose these three poisonous herbs, but used them very ordinary or bought them at will, it would be difficult for her to find the killer. But now, because of the particularity of Denghua ember, as long as she finds out who has used this herb recently, she can feel the melon with the vine.

Although the identity of the poisoner cannot be determined, this is at least an opportunity.

She first asked Liang Yuyan to help check the situation of the three herbs in the market. At the same time, she also informed Lin Yixuan that a two pronged approach can save time and know more details from different channels. After all, Luo qingluan has only five days this time. Time is urgent. She must prevent her opponent from getting in the way as soon as possible.

"What about the Wuyang palace? Is there any change?" Luo qingluan asked.

"Not yet. Everything is normal."

Liang Yuyan said: "After all, Zhao Ningyi is the only son of the king of Wuyang. He is naturally grieved after his death. However, due to the imperial edict of the southern Wei emperor and your identity as the princess, he has not made a public announcement for the time being, so the outside world does not know that Zhao Shizi is dead. However, the princess of Wuyang is not so restrained. She cried all day yesterday and said a lot of bad things about the princess. I really hate you if he didn't think about the princess's plan Don't block her mouth. "

Looking at Liang YuYan's hatred, Luo qingluan shook his head: "forget it, she lost her son after all. Although Zhao Ningyi is not very good, it's naturally different for Princess Zhao. We don't care about her."

"That's right."

With a slight frown, Liang Yuyan said, "when I went to check the herbs yesterday, I happened to see Princess Qinghe out. Although she was in a sedan chair, she happened to pass me, so I saw it was her."

"Shouldn't Princess Qinghe be at home with her mother at this time? Why are you still going out?" If so, Luo qingluan also feels something wrong.

"So I also felt strange, so I followed to have a look. As a result, I followed her all the way and knew that she was actually going to the second prince's house."

Luo qingluan suddenly felt wrong: "Zhao Xiu went to Lin Xiaochen? What are you doing?"

As far as she knows, Zhao Xiu is not deeply in love with Lin Yixuan and wants to be the crown princess as soon as possible. How can she go to the second prince's house alone, and at this time? Is she going to ask Lin Xiaochen about something, or if she has a clue about the cause of her brother's death, she will ask?

Nothing is right. These things are not what Zhao Xiu should do at all.

Only one thing, unless the matter is related to Lin Yixuan and Zhao Xiu's crown princess, she will never go to Lin Xiaochen. I'm afraid she's still hiding it from her family.

After listening to Luo qingluan's analysis, Liang Yuyan nodded: "indeed, I was careless yesterday and didn't expect to go here. However, princess, it's too late to hear what Princess Qinghe and Lin Xiaochen talked about. What should I do now?"

After thinking about it, Luo qingluan said, "don't worry. If they're talking about unimportant things, it doesn't matter if they don't know. If Lin Xiaochen needs Zhao Xiu to do something, we just need to stare at Zhao Xiu. She doesn't know we found it. Naturally, she won't be too careful. Yuyan, find someone to stare at her and see what Zhao Xiu is going to do."

……

In Yunyi Pavilion, the girl waited on her side carefully. The crying eyes of Princess Feng of Wuyang were swollen, and she still kept wiping her tears with a silk: "Ning Yi, my son... You died miserably..."

I can't imagine my brother's tragic death at all. Zhao Xiu tries to abandon the situation that night in her mind. For Zhao Ningyi, she didn't have much feelings. Even before, she was eager to have this brother. She was so ignorant and tasteless that she became his sister. It was a shame.

However, looking at Feng's so sad appearance, Zhao Xiu couldn't bear it: "Mom, don't cry. My father will avenge my brother. No matter who killed my brother, he can't run away."

"As soon as I saw the woman's hook, I knew it must be her."

He raised his head and showed a badly made-up face. Feng hated and said, "Your Majesty is also frightened by her identity for fear of offending the king of Chu. Otherwise, how dare that woman be so arrogant and poison your brother."

At the mention of Luo qingluan, Zhao Xiu was unhappy: "isn't it? Obviously she is the most suspect. Her Royal Highness the crown prince still protects her. She said that she is pregnant and works unceasingly. It's time to let her live in the crown prince's house. I'm not afraid that she will hurt herself!"

Although Lin Yixuan was nice to her in the past, and there was even a rumor that the empress wanted her to be the crown princess, compared with Luo qingluan, Zhao Xiu knew that she was inferior to her for the first time.

Not as good as her position in the heart of the crown prince!

"Mother, you said that if you really found out that Princess Chu killed her brother," Zhao Xiu tentatively asked Feng, "do you think your Highness the prince will shield that woman and even plead for her?"

As soon as Feng heard this, he also felt the seriousness of the matter. His son died and could not be reborn, but his daughter had to marry the crown prince. However, from the current situation, the crown prince's attitude towards the princess of Chu is indeed different!

In such a big murder case, the Prince did not hesitate to believe that he was even willing to go to the palace to intercede for her. Such an attitude has never been so kind to her daughter before.

Looking at Zhao Xiu, Feng Shi asked, "Xiuer, are you worried that if the crown prince likes that woman, isn't it?"

"That's not true."

Zhao Xiu has long thought clearly that even if the crown prince really likes Luo qingluan, she is the woman of the king of Chu and pregnant. It is impossible to have anything to do with the crown prince. At most, Xiang Wang has no intention of being a goddess. Over time, the crown prince will eventually forget her.

But what she was worried about was what the second prince Lin Xiaochen said yesterday.

Although he had little contact with the second prince before, Lin Xiaochen confided in her yesterday and talked about what she was worried about but didn't notice.

"Mom, my daughter means that if the prince continues to help the woman, what will she do if she takes the opportunity to ask the prince to do something? Such as destroying criminal evidence, buying witnesses, etc. it will be a great trouble to the prince at that time?" Zhao Xiuyue thought more and more worried, for fear that Lin Yixuan was really cheated by Luo qingluan.

As soon as Feng heard this, he suddenly felt that the problem was really serious. She saw the crown prince's attitude towards Luo qingluan with her own eyes. If the woman couldn't find evidence to prove her innocence five days later, the crown prince would certainly plead with her, but her royal palace of Wuyang will not give up. Your majesty also needs an explanation. If the crown prince goes to plead, I'm afraid it will annoy your majesty!

If the prince has a problem, it is bound to affect her Xiuer. Such a thing must not happen.

Looking at his mother's face, Zhao Xiu thought again and said in a low voice, "Mom, I see, do you want to do something?"

"Yes, you must not let that woman affect the crown prince." Feng's hatred surged up and his eyes were full of hatred. "Since she dares to kill your brother, we can't let her go unpunished. Xiu'er, go to the prince's house right away, no matter what excuse you use..."

Whispered something next to Zhao Xiuer. Feng hated and said, "it's about your position as Crown Princess and revenge for your brother. Xiuer, it's up to you."

At dusk, the setting sun slanted to the west, and the dark guard on duty at the gate of the prince's house was a little more leisurely.

It was time for the shift change again. The two teams handed over their work without the seriousness and tension of carrying out their tasks on weekdays. For them, although they stayed in the prince's house, they didn't think anything would happen.

As long as Princess Chu doesn't leave the house, the rest will do as usual. This is the imperial edict received by the dark guards.

After all, this is the prince's residence, but it's not the prince's guilt. They naturally show respect, and even are polite to the guards of the prince's residence. As long as five days, they can complete the task. For Luo qingluan, the pregnant Princess of Chu, they feel that the task is easy.

Soon after the handover, a new pair of people held the night. When Liang Yuyan came to the prince's house again, they didn't care. After all, Princess Chu must find evidence to prove that she didn't poison Zhao Shizi. As for the people who went in and out of the prince's house, it belonged to the guards of the prince's house and had nothing to do with them.

Soon, Liang Yuyan met Luo qingluan: "princess, your subordinates have found something about what you ordered."

At this time, Lin Yixuan also just came in. As soon as he saw Luo qingluan, he said, "qingluan, there is a result..."

When he saw Liang Yuyan, who was also in the room, he found someone, but it was important. He didn't have time to delay. He nodded at Liang Yuyan and told Luo qingluan the results: "my people went to Taiyuan hospital to check. In the last month, only Zhang Yaoshun, deputy envoy of Taiyuan hospital, used the medicine of lamp flower Ember. It is said that the people in the imperial dining room asked for it and said they wanted to match some rat medicine."

"Zhang Yaoshun, Doctor Zhang?"

Hearing this, Liang Yuyan also made a move in her eyes and immediately said to Luo qingluan, "coincidentally, among the people who treated Zhao Shizi, there happened to be Doctor Zhang Yaoshun. Moreover, I also heard that he just asked for leave yesterday and said that there was an emergency in his hometown. I think he must be suspicious!"
