After Liu Jingyi waited for Jing Ziyan to finish using the medicine, she came to the sachet shop again with a woman and a man accompanied by Han Che.

After Sun Xinglai's death, everything in the sachet shop was taken care of by Ding Yi.

As soon as Ding saw Liu Jingyi coming, he hurriedly stepped forward to greet him: "My lord, I don't know what happened to the small shop this time?" The villain has already told the adults everything he needs to know. ”

Liu Jingyi said: "When I came yesterday, I remembered that there was a pot of blooming flowers in Boss Sun's living room. Where is that pot of flowers now? ”

Ding Yi said: "The flower is still in the master's living room, it was given to the master by a good friend of the master, because the fragrance is special, the master has always liked it very much, so the flower has been in the living room and has not moved, I have been watering and maintaining it well in the past two days, which can be regarded as an explanation to the master." ”

"Take me to see the pot of flowers."

Ding Yi and Liu Jingyi came to the living room, and sure enough, the flowers were still there. Liu Jingyi carefully identified the pot of flowers, from the flowers to the leaves, to the flower soil, one by one, and she was sure that this pot of flowers was the same kind of flower as the pot of flowers in her room. Two identical flowers, why are the aromas different.

She carefully observed the pot of flowers, and she found that the flower soil had been moved, and under the leafy branches, there was an inconspicuous small plant, at first she thought that this was a young plant from this flower, but carefully distinguished, it was a completely different plant from the flower in the pot.

Liu Jingyi fiddled with the flower pot, quietly moved the small plant out of the flower pot, took out a handkerchief from the sleeve, wrapped the small plant, and restored the flower soil.

She asked Ding Yi, "Do you know where to sell this kind of potted plant in Liuzhou Mansion?" ”

Ding Yi replied: "There is a flower merchant surnamed Zhao in the west of the city, who specializes in serving flowers and plants, and the big families in the city go to them to buy flowers. ”

"You said that this pot of flowers was given by your master's friend, do you know this person?"

"I haven't seen him in real life, every time I come with a silver mask, Master seems to be very familiar with him."

This is a clue, Liu Jingyi thought. She decided to meet the florist that Ding Yi had mentioned.

Walking out of the sachet shop, she looked at Han Che behind her, a little helpless. Han Che is a stuffy gourd, he didn't say a word along the way, and kept an absolute distance from Liu Jingyi. She knew that Jing Ziyan hoped that Han Che would follow, it was to protect her safety, don't say that she knows some punches and kicks, but she can't punch and kick, she is a doctor, and she usually carries a certain amount of self-defense herbs in case of emergency, Jing Ziyan is indeed too worried.

Looking at Han Che's expressionless face, Liu Jingyi secretly complained. "Brother Han Che, do you think that me and Childe, who needs protection more?" Liu Jingyi said.

"This... Miss Jing, under the order of the son to protect the girl, the son said that the girl needs protection, then it must be reasonable. Han Che said innocently.

Liu Jingyi was blocked to internal injuries. "Brother Han, you said that with my face, who dares to murder me, I am scared half to death." Liu Jingyi's eyes rolled, "It's better to be like this, let's discuss, you see that since someone is plotting to kill Gongzi, then there must be someone who wants to be unfavorable to Gongzi, in this case, Gongzi's comfort is more important than mine." I think you need to protect Childe even more. ”

Liu Jingyi said as she nodded to herself.

“。。。。”

Seeing that Han Che didn't speak, Liu Jingyi continued to pout. "Brother Han, look, if Gongzi is investigating the case, if someone is unfavorable to Gongzi, wouldn't it be a lot of fun. Brother Han, you should hurry up to Childe's side to protect Childe, if something happens to Childe, we can't afford it, right?"

Han Che hesitated, obviously he was moved.

In this way, Han Che was supported by Liu Jingyi to Jing Ziyan's side. She went to the florist herself.

When I came to the flower shop mentioned by Ding Yi in the west of the city, it was indeed a big flower room, and there were all kinds of strange flowers in it. Liu Jingyi saw the blooming Nalan jacquard at a glance, stepped forward gently, and smelled the flowers.

"What flowers does the guest officer want to buy?" Seeing a thin man with a mask standing in front of the treasure of the town, although the man was thin, he exuded a compelling temperament, and the flower shop owner Zhao Gui was afraid that the person who came would not be good, so he hurriedly stepped forward. This man is none other than Liu Jingyi, who is dressed as a man.

"Boss, what is this pot of flowers called?"

"Keguan, this flower is called Nalan jacquard, produced in the Western Regions, low yield, extremely precious, is the treasure of the store's town store, this year the small shop has entered a total of three pots."

Liu Jingyi carefully observed the Nalan jacquard in the store. This pot of flowers is luxuriant, and it is corrected neatly, there are no side branches and leaves, and there are no extra branches and leaves at the bottom of the flower branches, which is clean and safe.

"Boss, I'm here to handle the Yamen of the Criminal Division." Liu Jingyi revealed her identity, "Boss, do you remember how many pots of this flower have been sold so far, and who have they sold to?" ”

Hearing that Liu Jingyi was on an errand by the Yamen, Zhao Gui was shocked, and said respectfully: "Forgive the villain for being clumsy, I didn't see the identity of the adult, and I ask the adult to forgive me." ”

Then he continued: "This year, the small shop has entered three pots of this flower, and so far two pots have been sold, one pot was sold yesterday, a teenage girl, the girl was very happy to see this flower yesterday, and said that she wanted to buy it for her own young lady, so that the young lady was depressed recently, and bought it back to please the young lady, so that the young lady changed her mood." ”

Liu Jingyi knew in her heart, this is perilla.

Zhao Gui paused and continued: "The other pot was bought by a man with a mask a month ago. Zhao Gui recalled carefully and said: "That person was dressed in a green coat, his whole face was covered with a silver mask, he couldn't see the real face clearly, and he was about 7 feet tall. He thought about it again and said with certainty, "Yes, with the left hand." ”

Liu Jingyi asked again: "Does this orchid jacquard need to be assisted by planting other plants in the pot in order to grow vigorously?" ”

Zhao Gui smiled, shook his head and said, "It seems that adults don't know much about serving flowers and plants, and for this kind of potted plant, the most taboo is to plant a variety of plants in a potted plant, which is a taboo for raising flowers." ”

When Liu Jingyi heard this, she took out the small plant removed from Sun Xinglai's house from the pot of Nalan jacquard in Sun Xinglai's house, and asked, "Boss, do you recognize this thing?" ”

Zhao Gui took the small plant in Liu Jingyi's hand, carefully observed its branches and leaves, and then leaned to his nose to sniff it, and said, "This is Peixin grass, I don't know where the adults got this thing?" ”

Liu Jingyi said: "It is from a pot of Nalan jacquard, which is covered by the lush branches and leaves of Nalan jacquard, so this thing grows thin and is not easy to detect. ”

Zhao Gui's face changed slightly. "My lord, this peixin grass itself is non-toxic, and when it is planted with flowers, it can induce the volatilization of some hidden toxins in the flowers, and over time, it can also change the original smell of flowers."

Liu Jingyi's face changed greatly, and she looked at Zhao Gui in surprise, "Then is this Nalan jacquard toxic?" ”

Zhao Gui nodded, "Nalan jacquard has a strange fragrance, but it is also slightly poisonous, after being induced, the smell makes people's hearts beat faster and dizzy."

Liu Jingyi's voice changed slightly, "Can Nalan jacquard be planted alone to have toxins?" ”

"Nalan jacquard has low toxin, and if there is no attractant factor, even if it is placed in the city, it is not easy to poison people."

Liu Jingyi remembered that pine and cedar incense is also very easy to induce the volatilization of poison toxicity. Liu Jingyi said in a deep voice: "If two inducing things are put together with Nalan jacquard, what kind of consequences will people cause when they hear it?" ”

"In severe cases, people will suffer cardiac arrest and die of heart palpitations." Zhao Gui said solemnly. "People with the poison of Nalan jacquard generally have rapid palpitations and cardiac arrest, but their faces are as usual, and it is extremely difficult to detect the cause of death."

"Does the pollen of Nalan jacquard change color when it encounters any substances?"

"Its pollen is indeed special, it will turn pink when it encounters acidic substances, so generally the dyeing mill will also use the pollen of Nalan jacquard as an ingredient for dyeing."

"As you said, Nalan jacquard is so expensive, how much pollen do you need to use as a dyeing ingredient?"

"Actually, it's an ingredient, but it's just to add some of this pollen to the dye formula, which doesn't require much, but Nalan jacquard has the effect of dyeing permanent color, so some good silk satin will choose to dye with it. Of course, the price is also very expensive. ”

Liu Jingyi's eyes narrowed, and her heart was suddenly in her heart. It turned out that Sun Xinglai died of heart palpitations caused by the toxin volatilized by Nalan jacquard, and the pink of Sun Xinglai's collar was originally dyed with the pollen of Nalan jacquard.

"Boss, do you know where this heart grass grows? Is there a place for us to grow in Liuzhou Mansion? Liu Jingyi continued to ask.

"This heartgrass likes shade and generally grows on the backlit shade side of the mountain. Liuzhou was originally backed by the mountains, maybe you can find this kind of peheartt grass in the mountains. Flower growers know the role of the flower, so the flower growers generally do not plant the flower. Zhao Gui said carefully.

At this point, Liu Jingyi has fully understood the cause of Sun Xinglai's death. Without further ado, she had to hurry up and tell Jing Ziyan about this discovery. After thanking Zhao Gui, she hurriedly walked in the direction of the Yamen of the Criminal Division.

At this time, Jing Ziyan had already returned to the yamen of the Criminal Department with Jiao Zhen. In the main hall of the back hall of the Yamen of the Criminal Division, Jiao Zhen was sitting at the top with a difficult face.

Liu Jingyi entered the main hall and bowed to Jiao Zhen: "I've seen my lord, son." ”

"My lord, childe, I know the cause of Sun Xinglai's death." Liu Jingyi then recounted her discovery in detail, and presented the peixin grass to Jiao Zhen.

"Now it seems that Sun Xinglai was indeed poisoned." Liu Jingyi said. "Just, why was he killed?"

Jing Ziyan said in a low voice, "Maybe this Sun Xinglai did something he shouldn't have done. ”

"I went to Yanfu with Master Jiao, and Lord Yan, who had already sent a message, told us that Miss Yan had been assigned to marry the fifth prince, and the marriage was originally scheduled to be completed in April this year." Jing Ziyan sighed and continued, "Who knows, since the beginning of this year, Miss Yan's body has been good and bad, and half a year ago, she couldn't afford to be sick, and this marriage has been delayed."

"No wonder last time I went to check Miss Yan's pulse, Lord Yan has always been grateful to me, and let me be commensurate with Miss Yan's sisters in the future, it turns out that there is still this relationship, if Miss Yan's illness has not been good, then this family matter will be done, and they will not be able to climb this layer of royal relatives." Liu Jingyi smiled bitterly.

Jiao Zhen, who had never interjected, said: "Hey, Miss Yan, she has always been famous in Beijing, and her piano, chess, calligraphy and painting are famous in Beijing, and many noble sons have expectations for this Miss Yan." Among them, there are many princes. ”

Jiao Zhen was two big, sighed and said, "Lord Yan said that before he was married to the fifth prince, the fourth prince asked him for Miss Yan before. ”

"Miss Yan was able to attract two princes to compete for it, which shows that her talent is extraordinary." Liu Jingyi said. "Then why didn't Lord Yan agree to the four princes?"

"The prince begged for a kiss, but Lord Yan didn't agree. Lord Yan agreed, but the prince must have the emperor to marry, and the fourth prince saw that Lord Yan agreed, so he went to ask the emperor to marry, but Lord Yan did not wait for the will of the four princes, but waited for the will of the five princes. ”

Liu Jingyi was slightly surprised, it turned out that there were such twists and turns in this marriage. "Why was he suddenly assigned to marry the fifth prince?"

"The five princes have preemptively decreed marriage to the emperor." Jiao Zhen said.

"That... Adults are skeptical... Liu Jingyi lightly opened her lips and did not continue.

"Hey, I didn't say anything, now that Miss Yan has recovered, the Ministry of Rites may reschedule her to consummate her marriage with the Fifth Prince." Jiao Zhen hurriedly denied it.

"We know more about these twists and turns, and it won't do us any good," Jiao Zhen said earnestly, "We just need to find the person who poisoned us at the moment." ”
