"So, your poisoning that day is related to the prince."

Chu Hongze was not asking her, but was very sure of this answer.

"Well, I was a little unwell when I just came out of the Prince's Mansion that day, if that's right, I should have been poisoned in the Prince's Mansion."

"Do you think there is anything in common with the poison of the Queen Mother?"

When Wen Ruyi saw the poisoning of the Queen Mother that day, he immediately linked it with his own poisoning, although it was not the same poison, but it was obvious that the poison in these two times was a rare poison, as the imperial doctor said that day, there are very few people who can make and solve this poison at present.

"Although I can't completely confirm that these two poisons are from the hands of the same poison maker, I know that this person is a master of drug production, and there is a high probability that they are the same person, but I haven't found evidence yet."

"In other words, if you can find out the similarities between these two drug productions, you can think that this poisoning incident outside the city and the poisoning of the Queen Mother are both from the prince's mansion."

Wen Ruyi thought about it and nodded, so to speak.

"However, these are also inferences, and specific conclusions can only be drawn after finding evidence."

Chu Hongze didn't reply, thinking about something.

After a while, he stood up, as if he was leaving, and Wen Ruyi hurriedly followed him to stand up.

"Are you leaving?"

"Hmm."

Wen Ruyi was very entangled, she didn't know if he was angry with her.

"Are you still angry?"

Chu Hongze's footsteps as he was about to walk towards the door stopped, he didn't turn around, but still turned his back to Wen Ruyi.

"Don't be angry, I have some things to deal with now, you just wait here for news, don't go anywhere for the time being."

Wen Ruyi was a little disappointed, he must still be angry about what happened just now, but now it is more important to investigate the poisoning incident, so he is not good at this matter.

"Oh!"

Wen Ruyi hung her head and sat down.

"Don't think about it, we'll find the murderer."

This time, Chu Hongze really left and didn't stay too long.

After Chu Hongze left, he found Wei Feng and then followed him to the scene of the crime.

So far, what he knows has been poisoned four times, one is that Wen Ruyi was poisoned in the prince's mansion, once someone poisoned the water of Rui Wang's mansion, and once he poisoned the queen mother, and finally the most serious poisoning, those nameless corpses outside the city.

"On that day, who was the first to discover that there was a problem with the water in the palace?"

"It's the butler."

Wei Feng remembers very well that he met the housekeeper that day, and then the housekeeper fell to the ground when he passed by him, and he was still conscious at that time, and the housekeeper told Wei Feng that there was something wrong with the water.

He hurriedly called the doctor and learned that he was poisoned, but he didn't know what it was.

On that day, he immediately went to see the other people in the house, there was no effect, he thought it was just that the housekeeper had eaten something wrong, after all, everyone else was also drinking this water, but only the housekeeper had a problem.

Unexpectedly, after a while, many people had the same situation, so he thought of the housekeeper's words and went to investigate the water, and sure enough, there was a problem.

"Call the butler."

Fortunately, the housekeeper found out early that day, so the people in the house were basically detoxified by Wen Ruyi in the end.

The butler soon came, and he respectfully saluted Chu Hongze.

"How did you find out there was something wrong with the water that day?"

The housekeeper didn't understand at first, but then Wei Feng reminded him in his ear, and he knew that Chu Hongze was talking about the poisoning of the palace that day.

"That day, I didn't eat anything, I drank some water, and then I started to get dizzy, very uncomfortable, and then I fainted, and before I fainted, I met Wei Feng and told him my guess."

"So, it's just your guess that there's something wrong with the water, right?"

The housekeeper nodded, yes, he didn't know the specifics, until later, when the princess came to tell them that it was indeed a water problem, he was a little lucky, fortunately he found it early, otherwise there would be only so many people in this mansion who were poisoned.

"Yes."

"Have you noticed anything unusual before, like the place where people often go to fetch water?"

The housekeeper recalled it carefully, and when the prince said this, he seemed to have some impressions.

"I think there is."

"Say!"

The housekeeper thought for a while and spoke: "Before that poisoning incident, I saw a few times that a subordinate from the princess's mansion often went there, I don't know what he was doing, I once met him, he looked panicked, I stopped him, asked a few words, he said that he came to find something for the princess, I saw that he was also an honest man, and I didn't make too many guesses, so I let him go." ”

Hua Zhen? Chu Hongze frowned, does it still have anything to do with her?

"Have you seen that person lately?"

"No, I haven't seen him since someone was poisoned when there was a problem with the water in the house that day."

"Is that the man?"

Chu Hongze took out the portrait of the man and asked the housekeeper to come forward to identify it.

"Somewhat like, it should be."

The butler wasn't sure that the man in the painting was somewhat similar to the man, but he couldn't guarantee that it was.

"When did this man enter the house?"

"This person was brought in by the princess herself one day ago."

"Go and call the princess."

Chu Hongze didn't expect this Hua Yan to be so bold, joining forces with the prince, planning to get rid of him?

After a long while, Hua Yan was late, and it could be seen from her clothes and makeup that she had been carefully dressed for a long time.

"Lord Wang, do you have any instructions for calling Hua Yan over so late?"

Hua Yan's voice was always so gentle in front of Chu Hongze, as if he was deliberately currying favor with him.

"This king asks you, is this man one of yours?"

This time, Chu Hongze threw the portrait directly in front of her, Hua Yan was stunned, and took two steps forward to pick up the paper thrown on the ground.

She looked at it carefully, and felt a little familiar, but she couldn't remember if it was someone from her house.

"This... Hua Yan doesn't remember. ”

Don't remember? Play stupid, huh?

"Okay, since I don't remember, then I'll change the way I asked, did you bring a subordinate back from outside before."

Hua Yan thought about it, it seems that there is such a thing.

"Yes, lord, if you don't like me to bring someone back from outside, I'll let him leave, and never again..."

"Where did you bring it from?"

Chu Hongze didn't have the heart to listen to her say those useless words.

"It's... It was Wen Dongling who gave it to me. Hua Yan saw that Chu Hongze's face was very bad, thinking that he had done something wrong, and hurriedly apologized: "I'm sorry, I... I really don't dare to bring people in from outside without permission in the future, I..."

Seeing her like this, Chu Hongze wondered a little in her heart, didn't she know who that person was? Or is it all she faked?

"Do you know who that man is?"

Chu Hongze raised his voice, startling Hua Yan and almost crying.

Hua Yan really didn't know what mistake he had made.

"I don't know... That person was really given to me by Wen Dongling, that day, I went to look for Wen Dongling, but a slave who traveled with me suddenly disappeared in his house, she said that in order to apologize, he brought this person back to me. ”

Chu Hongze glanced at her, this woman should really not know anything, it is estimated that she was being used, she is really stupid.

"Is that man still in the house?"

"It's gone, I haven't seen him in a long time."

Hua Yan knew that she must have made Chu Hongze angry, and she stood in place at a loss.

"This king knows, go back."

Hua Yan was a little lost, she just saw the housekeeper come to her, and when she heard him say that it was the prince who wanted to find her, she hurriedly and happily went to clean up and dress up, this was the first time he took the initiative to call her over, which was a surprise for her.

After the result came, I found out that he was looking for her for business, and she was really unwilling.

"Lord Wang, I..."

However, it is obvious that Chu Hongze did not intend to give her a chance to speak.

"Butler, take her out."

"Yes!"

Hua Yan wanted to say something, but Chu Hongze got up directly and went to the bedside and watered a few pots of flowers over there.

It seems that everything needs to be investigated from Chu Hongchen's side.

On the second day, Wen Ruyi got up early and waited at Chu Hongze's door.

When Chu Hongze pushed the door open, Wen Ruyi suddenly appeared and startled him.

"Why don't you knock on the door and go in?"

Wen Ruyi was embarrassed to say that she was worried that he was still angry, so she decided to wait for her outside.

"I'm afraid I'll disturb you."

Chu Hongze couldn't see her careful thoughts clearly, but he didn't plan to expose her now.

"Something so early?"

"Well, I thought about it for a long time yesterday, and I thought we should go to the scene outside the city to have a look, maybe something will be found."

Chu Hongze looked at her and motioned for her to continue.

"Because a poison maker like them doesn't mean that there are no flaws, if it's the same person, we will definitely find common ground."

"Well, wait for me, I'll go with you right away."

After Chu Hongze finished speaking, he called Wei Feng, walked to the side and instructed him something, and then walked over to her.

"Let's go!"

The crime scene outside the city is very cruel, maybe it has been a long time, and the faces of these people have all been swollen, not only on their faces, but also on their bodies, and they are almost completely unable to see the original faces of these people.

And the portrait of Chu Hongze before was painted when these people had just been poisoned and their appearance had not changed.

Wen Ruyi squatted down and carefully examined the corpses.

After a while, Chu Hongze squatted down beside her and asked her, "How is it?" What did you find? ”

"This time, this person did not poison indirectly, but directly used poison."

Wen Ruyi exposed the neck of one of them, there was a very inconspicuous needle eye on it, and she really couldn't find it if she didn't look closely, and then she went to see several other corpses, all of which were the same.
