Looking at Jiao Zhen's surprised appearance, Jing Ziyan nodded with a gloomy face.

Jiao Zhen hurriedly stepped forward and asked, "I don't know what to call the son?" Can Childe inform me of the details? ”

"Villain Jing Han, I've seen Master Jiao." In order not to reveal his identity at will, Jing Ziyan still used a pseudonym. Subsequently, Jing Ziyan told Jiao Zhen in detail how he fainted and how he found out. Jiao Zhen felt from the bottom of his heart that this matter was not ordinary. But as an envoy to the criminal department, he can't put this worry on his face. Jing Ziyan said: "My lord, can you allow the villain to investigate the case together." The villain can also be regarded as the bitter master of this sachet incident. ”

Jiao Zhen was in a dilemma for a while. In general, cases of state government prisons cannot be handled by people other than the government officials.

"But Jing Han is the bitter master of this case, even if he doesn't agree to him, looking at his appearance, he may start investigating the case himself, if he finds out, it will be unfavorable to the yamen to abuse lynching the person who poisoned him."

Thinking of this, Jiao Zhen said with a soothing face, "I don't know what the son does for a living?" I've heard that this sachet is so expensive that people who are idle can't afford it. ”

Jing Ziyan knew that he would have this question, and said, "The villain's family lives in Xiaotian Village and makes a living by selling medicinal herbs. Then he pointed to Liu Jingyi behind him and said: "This is the housemate Yi'er, who has been a doctor since she was a child, and she knows a little about medicine. ”

Jiao Zhen looked in the direction of Jing Ziyan at the thin man with a mask. Liu Jingyi hurriedly stepped forward and bowed her hand: "The little girl Yi'er has seen Master Jiao. ”

Jiao Zhen rubbed his chin with his hand and said, "It's easy to say, I was still suspicious just now, how could there be such a thin man, could it be a woman dressed as a man, sure enough." Jiao Zhen paused, as if remembering something, and continued: "I heard that Lord Yan of Zhishi said that the person who treated Miss Yan was a doctor surnamed Liu, could it be you?" ”

Liu Jingyi nodded: "It's the little girl." ”

"Oh, it's really young and promising." Jiao Zhen was even more sure at this time, to investigate this case, he needed to use Jing Han's power. "Jing Gongzi, it's not difficult for you to investigate this case personally, but the yamen has rules, and criminal prison cases must not be interfered with by people outside the yamen." Jiao Zhen paused and said, "Is Jing Gongzi willing to be wronged and investigate this case as a yamen commissioner?" ”

"If the adult allows the villain to personally investigate the case, it is the adult who exalts the villain, and the villain is wronged." Jing Ziyan said.

"Then how about Jing Gongzi as a famous master of the Yacha Punishment Officer, how about running an errand for this official?" Jiao Zhen asked.

"But by the dispatch of the Lord."

Jing Ziyan took Liu Jingyi back to the yamen with Jiao Zhen, and carefully recounted the situation that Liu Jingyi had told him before.

"According to what you say, this poisoned person started to lay out a year ago." Jiao Zhen said. "These two sachets, used separately, have no toxicity in the medicinal materials, but as long as they are put together, they will induce toxicity. This is the poisoning that wants people to be unaware of the ghost, and the poison of the person's mind is terrifying. ”

"My lord, as far as I know, the Liu family and the Zuo family also bought this expensive sachet at the same time, and the top priority is to find out whether anyone in the Liu family and the Zuo family is poisoned or unwell." Jing Ziyan said.

"Master, this case must be investigated, Lord Yan has been an official to worship the household department, although it has been sent to the scholar, we must not be lazy, let people have the mind of going to the tea." After many years of mixing in officialdom, Jiao Zhen has his own set of rules for officialdom survival.

"My lord, I will do my best in this case, and you can call me Jing Han in the future. In this way, I went to Liu's house and Zuo's house to inquire about the situation. ”

Without further ado, Jing Ziyan took Liu Jingyi to Zuojiazhuang. In the main hall of Zuojiazhuang, after explaining the intention to the owner of the village, Zuo Ren ordered someone to bring all the several sachets worn by the eldest lady of the Zuo family, Liu Jingyi opened them one by one and examined them, and suddenly exclaimed, "Childe. ”

Hearing this, Jing Ziyan hurriedly walked to Liu Jingyi's side, "Childe, the prescriptions for mosquitoes and insects in these sachets use borneol, not ice grass. ”

"What did you say?" Jing Ziyan's face suddenly turned cold as frost. "This means that the murderer has a very strong purpose." Jing Ziyan subconsciously felt that he had been involved in a huge conspiracy. "Let's go, let's go to Liu's Mansion and ask again."

After speaking, Jing Ziyan said goodbye to Zuo Ren and took Liu Jingyi to Liu's mansion, and the result was the same, the sachet purchased by the Liu family also used ice chips instead of ice grass.

The murderer's purpose has been clarified, that is, to target the Yan family. As for Jing Ziyan, whether it was intentional or unintentionally affected, it is not yet certain.

"Childe, I want to go and see Sun Xinglai's corpse." Liu Jingyi said suddenly.

Jing Ziyan glanced at Liu Jingyi and frowned, after all, Liu Jingyi is a girl's family, and she just cares for medicinal herbs every day, Jing Ziyan doesn't want her to deal with corpses.

"You are a girl's family, what kind of body is it to deal with corpses, I will go to examine the corpse again with the servants. You go to Sun Xinglai's house again to check the scene. Jing Ziyan said sternly.

"Childe, I'm a doctor, I've been dealing with medicinal herbs for many years, and I'm very familiar with all kinds of smells, so I may be able to find toxins and the like that I can't find. Childe, just let me go and see the corpse," Liu Jingyi said firmly.

Looking at Liu Jingyi's resolute eyes, Jing Ziyan knew that he couldn't do it, and said helplessly: "Okay, but when you get to the morgue, you have to listen to my orders." ”

Liu Jingyi nodded. Then he came to the morgue with Jing Ziyan.

Entering the morgue, Liu Jingyi took a deep breath, stepped forward and lifted the corpse cloth covering the corpse, although three or four hours had passed, the corpse's face was still lifelike. Sun Xinglai's corpse was indeed as Ding Yi said, with a peaceful face and a smile.

According to the report, Sun Xinglai died suddenly, not poisoned, there were no external injuries to his body, and after the autopsy, there was no abnormality in the internal organs. Liu Jingyi stepped forward to carefully examine Sun Xinglai's body, her face was as usual, she carefully recalled the medical books she had read, it was not poisoned, there were no other wounds, but she died suddenly, she had the impression that there were cases of death caused by sudden cardiac arrest.

However, cardiac arrest usually requires a trigger. If Sun Xinglai really died of cardiac arrest, then what was the trigger? She carefully observed Sun Xinglai's corpse and found that there was a trace of light pink staining on the white collar of his shirt.

"He burned incense," Liu Jingyi said to Jing Ziyan. "But in Sun Xinglai's shop, I didn't smell this fragrance, maybe it was Sun Xinglai's shop, all kinds of spices were mixed, so this fragrance was covered."

Liu Jingyi smelled to the servant again, "There is a little pink stain on the collar of Sun Xinglai's corpse, do you know what this stain is?" ”

He said, "This piece of dyeing is also quite strange, when I was performing an autopsy, I used autopsy vinegar, and accidentally dripped on his collar, and this collar became this color." ”

Liu Jingyi was taken aback. "Then why didn't you report it?"

"This... He whispered, "I don't think this has anything to do with the case. ”

Listening to the conversation between Liu Jingyi and Qi Zuo, Jing Ziyan had a judgment in his heart. "Yi'er, do you know what changes color when it encounters vinegar? I suspect that Sun Xinglai died of poisoning. ”

Subsequently, Jing Ziyan instructed Han Che and Mo Yu to go to Yanfu again to find out who Sun Xinglai sent by Yanfu to investigate.

"Childe, I want to go to Sun Xinglai's shop again." Liu Jingyi said.

"Okay," Jing Ziyan said, "I'll go with you." ”

In the end, they were not worried about Liu Jingyi herself, Jing Ziyan and Liu Jingyi returned to Sun Xinglai's sachet shop again. The apprentice Ding Yi was still in the store, and when he saw Jing Ziyan and Liu Jingyi coming, he hurriedly greeted him. "Two guest officers, I don't know what the two of you are doing this time."

Ding Yi's memory is not bad, he knows that these two are here to investigate the case.

Liu Jingyi said, "I want to take a look at the place where Boss Sun received guests before his death. ”

Ding Yi hesitated. Jing Ziyan said: "Now I am an official of the government. If you don't cooperate, you will be in the way of getting in the way. ”

Ding Yi immediately nodded and said, "The villain doesn't dare." Ding led them into the back hall.

This sachet shop, which leads directly to the front hall, has an antique furnishings, and the living room is separated by beaded curtains, and the hall has a strong smell of sandalwood.

Liu Jingyi looked around the back hall, this back hall is connected to the front hall, if anyone comes in the front hall, or what happens, the back hall can know the first time. There is also a back door in the back hall that leads to the backyard, which leads to the street. That is, if someone wants to escape, they can do so without going through the antechamber.

On the table in the living room, there was an incense burner for burning incense, Liu Jingyi stepped forward to pick up the incense burner with her hand, gently leaned it in front of her nose, and gently picked up the breath of the incense burner with her hand, and her heart trembled slightly. The incense burner has a scent other than sandalwood.

She had a little guess in her heart, and looked up and asked Ding Yi: "Did you burn incense during your master's reception?" ”

Ding Yi looked up at Liu Jingyi with a weak heart, "Master has always had the habit of burning incense, so as long as Master meets guests or mixes incense here, he will burn incense." ”

"Then what kind of incense does your master usually use to burn?" Liu Jingyi continued to ask.

"Master loves sandalwood and agarwood the most."

"Then do you know what kind of incense your master burned this time?"

"It's sandalwood," Ding Yi said.

"Are you sure?" Liu Jingyi continued to ask.

"yes, I'm definitely sandalwood." Ding Yi said. "Every time Master burns incense, the incense used is prepared by Master himself, and Master is obsessed with incense, so he is extremely precious to incense, so the incense used by Master on weekdays is generally not touched by others."

"Do you know where your master's usual incense is?" Liu Jingyi asked.

"Oh, the incense used by Master is all in a special incense box, you wait a minute, I'll go get it for you." Ding Yi trotted to get the incense box used by Sun Xinglai. After a while, Sun Xinglai came to Liu Jingyi with a rectangular box.

"My lord, this is the incense box that my master uses on weekdays."

Liu Jingyi covered her nose with a handkerchief, gently opened the incense box with her hand, carefully observed the incense in the incense box, and gently smelled the breath in it, no, this is not the smell of sandalwood.
