"Don't do it, I'll study a bottle of botanical herbal hair dye for you when you get back, and your hair will be black and bright immediately after dyeing, and you will be rejuvenated."

"Got that good thing? It won't rain and get ink, right? Are there any ready-made ones? Concubine Hui will be skeptical.

Leng Qinghuan glanced at her: "I don't have the heart to fix it now, I'm thinking about how to save your son from the dire situation." You said that the barracks were so peaceful, and there was nothing going on. I want to find some trouble, and I can't get out of the palace gate. Trapped here, he can't do anything, he can't say anything, and he is still under the nose of his father, and if he is a little troubled, he can't hide it. ”

"It's not simple, I'll leave it to Linfeng to do. I have a channel of communication, and your father doesn't know it. ”

"Facing the wind?" Leng Qinghuan's eyes lit up: "You let him think of a way first, let me go out of the palace and go out to touch a cannon fodder." ”

Concubine Hui didn't understand what this cannon fodder meant, but Leng Qinghuan said that there was a way, that is, there was a way, she inexplicably added a little confidence to this daughter-in-law, and immediately ordered someone to bring a letter to Shen Linfeng.

The next day, Leng Qinghuan saw Shen Linfeng.

The emperor's chamberlain came to the Pujia Palace and was ordered to pass on a decree to let Leng Qinghuan follow Shen Linfeng out of the palace and assist him in investigating the case of Lord Wei's death.

Leng Qinghuan had already calculated how to act today last night, but Shen Linfeng found an excuse to get himself out of the palace, so he immediately packed up and followed him out of the palace.

Shen Linfeng was waiting at the gate of the palace, and when he saw her, he smiled at her, revealing a mouthful of white teeth.

"My cousin-in-law is feeling better today?"

Thinking of the crying scene in front of the emperor yesterday, Leng Qinghuan was really a little embarrassed: "It's much better, it's much better." ”

"I'm sorry to trouble my cousin again."

So polite? There are no outsiders here again, who is acting for?

Leng Qinghuan also said politely: "It's that I'm embarrassed, I always trouble you." It's such a small thing, and I want to ask you for help. ”

Shen Linfeng was a little surprised: "What help?" ”

Leng Qinghuan was also stunned: "You didn't receive the message sent to you by your aunt?" ”

Shen Linfeng shook his head: "I was busy with the case for a day yesterday, I had no clue, I didn't return to the National Mansion, and I didn't receive any message, what's wrong?" ”

Didn't receive it? Could it be that he was cut off by the emperor's father again? I know that my mother is unreliable, she is not successful enough, she is the first to be mischievous, and she feels complacent and secret, and she is really blessed to be a woman who is stupid to her.

Thanks to the fact that he did not plot anything shady, the emperor also allowed him to go out, is it a tacit approval?

"There's nothing to do, I just want to find an excuse to go out of the palace to relax. What about you, what are you looking for me? Could it really be for this case? ”

Shen Linfeng nodded: "It's inconvenient to talk here, let's talk while walking." ”

Leng Qinghuan got into the carriage that Shen Linfeng prepared for her, and Shen Linfeng rode a horse and walked side by side with the carriage. When he got to a sparsely populated area, he briefly told her about the case.

The official who was killed this time was the right attendant of the Ministry of Officials, surnamed Wei, and the time of murder was the second watch last night. The first to be discovered was his original wife, Lin.

The cause of death, like the previous killed officer, was poisoning. The poison was also put down in a cup of green tea on the table, and after taking it, he died violently immediately.

And it was none other than his wife Lin who brought tea to this Wei Shilang.

According to Lin's confession, Wei Shilang has not slept very well recently, and he is often anxious and sleepless at night. She took it upon herself to replace Tieguanyin, which he liked to eat at night, with Longjing and sent it to him personally.

When the tea was brought into the study, the little grandson was asleep, crying and looking for his grandmother, so she turned around and went to put the little grandson to sleep. It wasn't until the little guy finally fell asleep and turned back to the study, and when he saw that the light was still on, he pushed the door in, urging Wei Shilang to go back and rest quickly.

As a result, I saw Wei Shilang lying motionless on the table, bleeding from his mouth and nose, and he had been out of breath for a long time. According to the examination, the poison fell in the tea in front of him, colorless and tasteless, but blood sealed his throat.

And the guard at the door of the study explained that after Lin left the study, no one else entered. Therefore, Lin has the biggest suspicion.

However, according to the people in the house, Lord Wei and the Lin family are a husband and wife in distress, with three children, and they raise their eyebrows and respect each other like guests, and the Lin family really has no motive to start.

Wei Shilang also had no suicidal tendencies.

This case has similarities with the last case of murder in a closed room, and Shen Linfeng is at a loss, after all, the last case is still unsolved, and this time there are no clues.

He hoped that Leng Qinghuan could see some clues from the poison in Lord Wei, and the most important thing was the poisoning method.

Leng Qinghuan roughly understood the facts of the case, and followed Shen Linfeng directly into the Shilang Mansion, which was naturally unimpeded.

Before he reached the door of the study, Shen Linfeng's face suddenly changed, and he took two steps quickly, and roared: "What are you doing?" ”

Leng Qinghuan looked fixedly, and the thick smoke was billowing from the study, drilling out through the cracks in the open doors and windows, and something was obviously burning inside.

Shen Linfeng stood at the door and glared at the people inside: "Didn't you explain in advance that no one is allowed to enter and leave at will and move the things inside?" ”

There was a person dressed in filial piety clothes and wearing a filial piety hat to greet him, his eyes were red, his face was sad, and he arched his hand at Shen Linfeng and said: "The house invited the master to spend time for my father, and the master said that we need to come to the place where my father died to burn some paper money, we didn't touch anything here, and we will leave after burning." ”

Out of sensitivity to the case, Shen Linfeng asked a few words about the background of the so-called "master", and then went in to check it out, and then waved his hand.

The paper money had been burned, and Wei Gongzi kicked the charcoal basin back to the corner of the table, and waved his hand to leave with the people in front of him.

Shen Linfeng stopped him: "Where was this charcoal basin originally?" ”

"It was in this location that my father used to burn some of the obsolete correspondence."

"Does he exchange a lot of letters on weekdays?"

Wei Gongzi shook his head: "It's not much, official transactions are generally sent directly to the Yamen of the Ministry of Officials." ”

Shen Linfeng glanced at the well-organized and spotless study, which showed that this Wei Shilang was very particular about his daily life. If this charcoal basin is not commonly used, why should it be kept under the soles of your feet?

He nodded, indicating that he understood. Then he pointed to the remaining half of the tea on the table, and said to Leng Qinghuan: "It's this tea, I specially ordered someone to keep it." Cousin-in-law, take a look, what clues are there? ”

Leng Qinghuan wore disposable gloves on his hands, picked up the tea cup, and put it on his nose to sniff lightly. As Shen Linfeng said, it is colorless and tasteless, and it is impossible to identify what kind of poison it is simply by virtue of the sense of smell.

She immediately started the mass spectrometry detection in the nano ring, and the results were soon available, but this poison was nothing special except that it was extremely toxic and instant.

However, she found something else unusual in the teacup.
