Queen Wei rested for two days. Her physical strength has recovered a lot and she has the spirit to speak. But her face was still pale and bloodless, because Biyun had to seriously paint empress Wei every morning and hide her pink face as pale and haggard, which was in line with her identity as a "seriously ill person".

After eating a bowl of lotus seed soup brought by Biyun, empress Wei lay in bed again. Luo qingluan went over and asked about the coma that morning. If the cause of Queen Wei's poisoning is not found out, it is likely to be caught again accidentally, so Luo qingluan must confirm this.

Hearing Luo qingluan's question, empress Wei thought about it and frowned. She seemed to recall what happened three days ago: "that morning, the palace was reading, but later she saw that the weather was good and wanted to go out for a walk."

Queen Wei also knew that her physical condition was not very good. She usually took a rest in the yard and rarely went to the imperial garden. Therefore, even though the weather was very good that day, she didn't go far.

Biyun nodded: "yes, Miss Luo, I just accompanied the empress that morning and walked around the yard outside."

Every place is the key to empress Wei's actions that day. Luo qingluan must understand the process in detail. Make sure again whether queen Wei ate anything special.

Queen Wei shook her head and said, "no, the palace didn't have a good appetite that day. She ate some porridge in the morning. Even when Biyun gave me fruit, I didn't eat it."

Since this was said by Empress Wei herself, Luo qingluan believed that there should be no omission: "the empress, think again, do you smell any strange smell in the yard, or touch anything special?"

As a doctor, Luo qingluan knows the possibility of poisoning very well. After all, Queen Wei is not in good health. I'm afraid a little dose will make her attack. Whether it is air contact or touching anything, these may expose queen Wei to Mengtuo grass.

Empress Wei thought for a moment and spoke slowly: "I remember that the roses on the courtyard wall bloomed well that day. I like it very much, but should there be no problem with this?"

The rose is not poisonous, and Luo qingluan also checked the rose that day, and there was no sign of being poisoned, so this can be ruled out.

"What else..." empress Wei continued to think and said with some uncertainty: "by the way, Biyun, didn't our palace feed fish that day? But those fish are alive and kicking. There's no problem? Won't anyone poison the water?"

Suddenly thinking of this, Biyun immediately nodded and said, "Oh, yes, my mother, is there a problem with the water? Because my mother touched the water when feeding the fish, so she was poisoned?"

Luo qingluan shook his head: "this should not. If fish can survive in the water, the water must be no problem, just..."

Now that there are doubts that have not been found before, Luo qingluan plans to have a look anyway.

Out of the door, Luo qingluan saw the cloisonne aquarium under the big banyan tree in the middle of the courtyard. Walking over, she saw that the fish in the water tank were still cheerful and lively, swaying around, and she couldn't see anything different.

Isn't it the problem with this fish tank?

Luo qingluan secretly mocked and thought he might have thought too much. She was about to leave when a flash of light flashed in her mind. It seemed that she thought of something. She immediately turned and asked Biyun beside her: "by the way, is there any fish food that my mother fed to the fish that day? Show me."

Biyun nodded, turned and ran back to the house. A moment later, he came out with a red sandalwood box. When I opened it, the box contained all the fish food that queen Wei usually fed to the fish. It was packed in small squares with a silver spoon inside.

Luo qingluan took the wooden box and put it in front of his nose. Suddenly, a faint smell of dream camel grass penetrated into his nose.

As soon as his eyes brightened, Luo qingluan was surprised and said, "that's it!"

"What, is this fish food?" Biyun didn't react yet and looked surprised.

No wonder she had never thought that the original problem was the fish food. Although Luo qingluan had nine points of doubt, she had to experiment in person to be sure. She scooped some fish food with a silver spoon and put it into the fish tank. Immediately, fish rushed up and swallowed the fish food one by one, which was very interesting.

But Luo qingluan was not playing. After feeding a few spoonfuls of fish, she stopped and carefully observed the reaction of these fish. As time went by, the fish soon ate up the fish. Biyun waited for a while and found nothing unusual.

She was a little strange: "Miss Luo, you see, there's nothing here. It shouldn't be the problem of fish food..." before she finished, there was something wrong with the fish in the fish tank.

Several fish obviously swim very slowly, and there are some signs of tumbling, like dying. After swimming for a while, the fish seemed to want to move, but there was no way. Gradually, they swam more and more slowly. Finally, they stopped moving and floated directly on the water with their stomach upward.

Biyun widened her eyes: "ah... Miss Luo, these fish are dead!"

"Dead? I'm not sure."

Luo qingluan grabbed a fish directly, looked at it carefully and shook his head, "No, these fish have eaten fish food, but at least they are not dead yet. The fish are poisoned by the fish food, but the physical conditions of the fish and people are different. Although the mother will be poisoned and unconscious when she comes into contact with these fish food, the degree of coma of the fish is different. It is estimated that these fish may recover in a while."

The actions of Luo qingluan and Biyue in the courtyard also attracted Xiao Yuqi. He walked over with his hands down and asked, "what's the matter?"

Biyun hurriedly said, "Your Highness, come and see these fish."

Xiao Yuqi just looked at it and his face sank. Luo qingluan handed over the things in the wooden box. Xiao Yuqi naturally understood what she meant. The feeling of the other party was to put the poison in the fish food and infiltrate the poison into his body with the opportunity of feeding the fish by his mother.

Luo qingluan nodded: "it seems that the person who poisoned specially knows the physical condition of the empress. If ordinary people touch such a little poisoned fish food, they won't be in a coma even if they have some physical discomfort, dizziness and other symptoms. However, the empress has always been in poor health. If they touch it a little, they fainted."

Xiao Yuqi's face was heavy: "Biyun, who is usually responsible for these things?"

Biyun hurriedly said, "Your Highness, these things that your mother feeds fish are sent by grandpa Wang."

The Duke Wang in Biyun's mouth is Wang Chu, the eunuch in charge of Fengwu palace. At the mention of this name, Xiao Yuqi knew that Wang Chu, as the eunuch manager, had been with his mother for more than 20 years. He had been with his mother since she was still a crown princess. If you say the degree of loyalty, there should be no problem.

Xiao Yuqi's face gradually eased: "since he is not the crown prince, it must be that the people around him secretly changed the real fish food and added toxic substances."

Luo qingluan nodded: "Your Highness, at this critical moment, you can't scare the snake at will. If you wronged the wrong person, you might make the suspect wary. If you want to investigate, you'd better do it quietly."

Xiao Yuqi also wanted to catch the murderer immediately and avenge his mother, but now he also knows that he can't be careless. The truth will come out soon. He can't miss it at this critical time.

He called his confidant and carefully ordered him to leave.

Recalling what had happened just now, Xiao Yuqi arched his hand to Luo qingluan and said, "Miss Luo, thank you very much. If you hadn't remembered that there might be a problem with fish food, we don't know where to start the investigation."

Luo qingluan smiled and didn't answer. She just wanted to repay Xiao Yuqi for saving her life. Besides, after contacting queen Wei for such a period of time, she didn't want an accident to happen to Queen Wei. After all, Queen Wei is a real mother in the world, much better than that vicious woman.

Luo qingluan handed over the investigation to Xiao Yuqi. Seeing that she was ready to leave the palace, Xiao Yuqi always sent Luo qingluan to the gate of Fengwu Palace: "Miss Luo, thank you these days. Since your mother is all right, go back and have a good rest."

Luo qingluan nodded, but asked him something unexpected: "does your highness know anything about Princess Li's family?"

Luo qingluan didn't expect so many twists and turns.

From the beginning, I ran into Xiao Tianci bullying men and women in the street. Because Luo qingluan couldn't see it, she did it easily. But when she learned that Xiao Tianci was actually Li Fengnian's grandson, she began to punish him severely. As for whether it was the hatred of imperial concubine Li, or whether she had long hated queen Wei before she laid hands on her, Luo qingluan didn't know, but she always felt that there was an invisible line involved in all this.

Since the safety of empress Wei has been solved, naluo qingluan also hopes to learn some news about Li Fengnian from Xiao Yuqi. Since the dark night hall investigated Li Fengnian, it also fought for it, which must have a lot to do with it.

Xiao Yuqi frowned: "did Miss Luo ask Li Shangshu?"

Although he didn't understand why Luo qingluan was interested in Li Fengnian, Xiao Yuqi said positively: "Li Shangshu has a good reputation. He has tried his best to share his worries for his father for decades and won the trust of his father."

"Well..." Luo qingluan paused and said, "if I say... This Li Shangshu may collude with the enemy country, will the crown prince think I'm alarmist?"

I thought Xiao Yuqi would be angry and wouldn't believe it, but unexpectedly, Xiao Yuqi didn't speak for a while, but his face was a little dark.

Luo qingluan's heart moved: "Your Highness, have you ever doubted this?"

Although he was still the crown prince, Xiao Yuqi was deeply trusted by Dongwan emperor and had been allowed to listen to politics in the upper hall. As the Minister of household of Dongwan state, Xiao Yuqi will naturally pay attention to it. He also has some confidants and counselors of his own. He once had a detailed understanding of Li Fengnian. It is precisely because of something that aroused his doubt. Otherwise, Xiao Yuqi would not have thought that Li Fengnian might be doing something behind his back.

However, he never found evidence, and he was just skeptical. After all, Li Fengnian was in a high position. His every move, words and deeds were related to the people's livelihood of Dongwan country.

Even Xiao Yuqi dared not show his attitude before there was no absolute evidence. If he hadn't heard Luo qingluan talking about this today, he would never have been touched.

"What did Miss Luo find?" Xiao Yuqi looked at her.

Did he really have doubts, but there was no evidence? Luo qingluan shook his head: "no, I just heard about it. It can't be true. Since your highness is the prince of Dongwan, you should be careful. I'm just reminding you."

Xiao Yu Qi arched: "thank you, Miss Luo."
