It is not surprising that Ningzhu screamed loudly before she died, as if she was trapped in a nightmare. Shen Qingzhi was poisoned before her, and she was poisoned to death. The cause of her series of abnormal behaviors was naturally the poison she was poisoned.

Shen Qingyu felt that the source of the poison was a good entry point. She carefully recalled Shen Qingzhi's words, "She waved her hands and kept shouting "go away", "eye", "go away", "eye" and other words while shouting

A lot of things were pushed down as she stepped back, and then she fell on her back, still shaking after falling."

Judging from the signs she described, Shen Qingyu guessed that the poison in the condensation beads was not the same as Shen Qingzhi's. Maybe it was some kind of neurotoxin poisoning, which caused the poisoned person to hallucinate, so she yelled and walked away, her eyes and the like

.

That's probably it, she thought uncertainly.

It's a pity that she knows nothing about poisons and has no way to determine what the poison is. Now she can only understand the poison that Ningzhu has been exposed to by asking someone to find out what the people in the government office have concluded.

The situation soon became clear, but unlike her previous conjecture, the poison in the condensation beads was speculated to be the same type as Shen Qingzhi's, but it was just the different degrees of poisoning that led to such seemingly different reactions.

To Shen Qingyu's disappointment, the government officials could not find the source of the poison, which meant that they could not determine how the condensation beads were poisoned.

The government officials investigated the people who came in and out of the courtyard in the past two days and found no one suspicious, which undoubtedly made the case more complicated and confusing.

But what surprised her even more was that there was a long period of time between when Ningzhu shouted loudly and when she died. The people around Shen Qingzhi were so panicked and allowed Ningzhu to go crazy until she died. I heard that those people

He felt that Ningzhu was going crazy, so he just escorted Shen Qingzhi out safely. When he looked back, Ningzhu was already dead.

For the sake of Shen Qingzhi's health, the doctor was obviously not far away. If the doctor had been called earlier, maybe Ningzhu could be saved. Shen Qingyu breathed out, feeling that maybe she was thinking too much. Shen Qingzhi was poisoned and the doctor was fine.

Grasp it, let alone condense it.

She was lost in thought when Ruyi, who she had sent out to talk to the people around Shen Qingzhi, came back.

She grimaced and begged, "Girl, can you please stop asking me to inquire about these things? I really can't do this kind of thing."

At this time, Shen Qingyu missed Qiaohe especially. He was a master at collecting information, but who told her not to bring him with him!

Shen Qingyu didn't answer Ruyi's words, but just asked: "How is it? Did you ask anything? I remember that aunt told Ningzhu not to get close to the fourth sister these days, why did she go there again today?"

"The fourth girl said that Ningzhu is so skillful that she can't do without her every morning when dressing up. I called her over early in the morning today," Ruyi replied.

Shen Qingyu frowned, "How much do you know about this condensed bead?"

Ruyi shook her head, "Although it has been a few months since the eldest master and his family returned home, this servant has only followed you, the girl, and has never interacted with her at all."

"But..." Ruyi thought for a moment, then continued, "But I have seen her twice, and she was following Miss Shen San."

Miss Shen San? Shen Qingyuan, is she involved in this?

Rao Xue, who had been silent and had a low sense of presence, said: "Ningzhu was originally the maid next to the third girl."

She saw Shen Qingyu's inquiring eyes turning to herself, and then explained: "Because of her good hair combing skills, Ningzhu was named by the fourth girl and asked to come from the third girl."

Ningzhu was originally Shen Qingyuan's maid. Could this be an important clue? Shen Qingyu had a vague guess.

But at the same time, Shen Qingyu had more questions that she couldn't figure out. For a moment, she didn't even know where to start. She thought she could check the poison, for example, by going to a nearby drugstore to ask if anyone had bought the drug, but she couldn't.

I found out that her idea was too simple and it wouldn't work at all.

Start from the beginning! Shen Qingyu looked at Rao Xue and Ruyi in the room, and waved them forward. She knew that her own ideas were very limited, so she wanted to hear their opinions, say opinions, but more

Hopefully someone can discuss the case with her.

She originally wanted the three of them to sit at the table to discuss, but Ruyi and Rao Xue refused to sit down, so she had to let them go.

"The night we first arrived, Ningzhu yelled that someone was looking through the crack in the door. She also said there was a knock on the door. Besides her, there was a girl in the house at the time, but the girl was very sleepy at the time and only said

I vaguely thought I heard a knock on the door. How likely do you think she is to lie?"

Ruyi was confused, "Why would she lie? If it is found that she deliberately caused confusion, she would be in trouble."

Shen Qingyu couldn't think of an answer, but she remembered her previous discovery and said: "Ningzhu mentioned that the knock on the door was made twice, the first time there was one sound, and the second time there were many sounds.

I found a stone in front of my fourth sister's door, and combined with the marks on the door, I think the first knock on the door was probably the sound of a stone hitting the door."

"Girl, what do you mean, the first knock on the door and the many subsequent knocks were not made by the same person?" Rao Xue was also surprised.

Shen Qingyu nodded, "The person who threw the stone didn't come into the yard at all. If someone came in, it would be meaningless to knock on the door with a stone, so I guess the person who threw the stone has nothing to do with the next knock on the door."

Ruyi scratched her head, "Then who knocked on the door? Who was the person who peeked through the crack in the door? No strangers sneaked in? And after Ningzhu shouted, many people in the yard soon responded.

We came over and went out to check, but we didn’t find anyone suspicious.”

"That's why I asked you how likely you think Ningzhu is to lie. It may sound a little incredible, but I think this is the most likely." Shen Qingyu clenched her hands unconsciously, "Ningzhu was lying. What happened later?

The knock on the door was her own. The fourth sister was already asleep at the time, and the other little girl was sleepy. Even if the knock on the door came from inside the house, I'm afraid those two people wouldn't be able to tell the difference."

She took a teacup on the table and put it on the table, "We assume this is the fourth sister. The poison in the fourth sister is the same as the poison in the condensation beads, but her symptoms are much milder. The person who poisoned her first time

The amount of poison may not have been controlled well, so the fourth sister was saved."

She took another cup and put it on the table, "This is Ningzhu, but she was poisoned and died. Do you think the murderer wanted to kill the fourth sister and accidentally poisoned Ningzhu, or is it possible that Ningzhu was the target?"
