After eating with a round stomach, An Ying burped and followed Yun Pingshi to Master Guo.

Xiao Yi was already at Master Guo's place, sorted out the situation of Jinling Mansion Academy, and said: "Jinling Mansion Academy is located at the foot of the West Mountain in the north of the city, and it is the best academy in the capital and the country. The students involved this time are mainly a few students from the Jiazi class, all of whom are going to take the provincial examination next year. ”

"Zhu Zhuzhi, that is, the student with zongzi. The eldest son of the third room of the Zhu family in the north of the city. The Zhujia family in the north of the city is also a family with a foundation in the capital, I heard that there are many officials, and there are fertile fields and mountains and forests, and the family is rich. Now the Zhu family's big mansion lives in three rooms and more than 40 people. Zhu Zhuzhi has always had good grades, and I heard that there is no problem with passing the provincial examination next year, so I am waiting for the Jinshi exam. ”

An Ying muttered: "Well, there are more than 40 people in the third room, and the people are very prosperous." ”

Xiao Yi smiled, "The eldest of the Zhu family has accepted a three-room concubine room, the second child has a four-room room, and the third child not only has three concubines at home, but also nostalgic for the Qinglou Wine House." ”

Lao Guo shook his head and said: "The Zhu family used to be very prosperous, and a few years ago, they also had a book in the household department, and now they are also eating the old book." ”

Xiao Yi said again: "Shen Pingxiu, one of the students present that day. Good grades, first class. ”

Yun Pingshi said: "I know Shen Pingxiu's father. His father has read books for most of his life, and he hasn't even passed the provincial exam, so his talent is a little worse. Usually wealthy families provide for studying, but his family is mediocre, he only got married in his twenties, and he has been studying for exams since then, all of which are provided by his wife. Shen Pingxiu's money for studying was still from the Shen family in Huzhou. The elders of the Shen family felt that he had a good future in the future, so the clan gave some money to subsidize him. ”

An Ying let out an "oh", thinking that it was probably Mrs. Shen's handiwork, she has always liked to invest, invest in industries or people.

"The other one is Yang Ye. He worked as a miscellaneous worker in our criminal department and did record-recording work, and he was also recommended by the college. He was also there that day. Yang Ye's situation, you all know that the son of Yang Zhutou, the head of the Beijing Mansion, has a perennial first-class grade, and he studies by receiving the rewards of the academy and the subsidy of our criminal department. ”

Xiao Yi said: "I think this person is very suspicious. Liang Su, Shandong Liang family. The Liang family has been a doctor for generations, and his ancestors were the imperial doctors in the palace. Judging from his family background, he understands medical skills, you see we are basically sure that the poison that poisoned Zhu Kexin came from oleander refining, and this refining requires technology, ordinary people ......"

Guo Xi knocked on the table, "Xiao Yi, don't jump to conclusions, you introduce others first." ”

Xiao Yi reluctantly took out another stack of paper.

"Feng Mo, a native of Baofeng, Yuzhou. A few years ago, I passed the Yuzhou Provincial Examination, came to the capital to take the Jinshi examination, and then entered the Jinling Mansion Academy. The family is a farmer, and his hometown has married a wife, in addition to studying in the academy on weekdays, he also copies books for the bookstore to earn some money. ”

"The last one is Yang Shen. A native of Quanzhou, he is more special, he was originally in the army, but five years ago he abandoned the military and followed the literature, and he was the third in the Fujian Provincial Examination. After arriving in the capital, he took the Jinshi examination and failed repeatedly. He was introduced to Jinling Mansion Academy to study. ”

An Ying asked while looking at the case file, "Why doesn't Zhu Kexin, who was poisoned, have no information?" ”

Xiao Yi was stunned and said: "Zhu Kexin is neither a murderer nor a real victim, so there is no investigation into him." Do you think he poisoned himself? ”

An Ying read the case file at a glance and said, "I just think that everyone involved in the case must be carefully investigated. ”

Guo Xi tapped his fingers on the table and nodded, "Zhu Kexin, the nephew of Zhu Yu in the imperial history." He is a native of Wu County, Jiangsu, and is a cousin of the Zhu family. When I first came to the capital, I lived in Zhu's house, and then I lived out by myself. There is not much information about him in Jinling Mansion Academy, I talked to the head of the academy, he originally studied in Wu County, and he had some talents, so he was sent to the Zhu family at home, and was introduced to Jinling Mansion Academy through the Zhu family. ”

Yun Pan finished reading the case file and said: "The adults focus on these six students, and I also agree with this very much. ”

Xiao Yi was a little puzzled, "Why?" In case it was poisoned by a gangster on the road, or by someone in the kitchen of the academy, these are all possible. ”

An Ying said slowly: "Lord Guo has written the inspection slip in the file at the back, and judging from the degree of poisoning, the poisoning will not take more than six hours. And Zhu Zhuzhi set off from home in the morning to the academy, the poisoning at home has been eliminated, they cooked zongzi to eat that night, although Zhu Zhuzhi stopped twice on the road, but the zongzi gift box was watched by the coachman, and there was no chance for outsiders to get close. “

"That is to say, the time period when the zongzi is poisoned can be narrowed to two hours from noon to dinner in Zhu Zhuzhi, and the people who can come into contact with the zongzi in these two hours are these five people and the people in the kitchen."

Yun Pan nodded with satisfaction and continued: "The kitchen person is responsible for the three meals a day of the entire academy on weekdays, if you want to poison Zhu Zhuzhi, you can poison Zhu Zhuzhi's food at any time, but you don't have to deliberately poison the zongzi that Zhu Zhuzhi brought." “

At that time, Zhu Zhuzhi also told the people in the kitchen that this was for his classmates to eat, and the success rate of poisoning was too low at this time. This case is strange, this way of poisoning feels very casual, and there is no special direction. ”

Xiao Yi was even more confused, "Then according to what you say, isn't this just an accident?" Is there really a murderer? In case someone in the kitchen mistakenly put poison or something, how can you find out? ”

Yun Pan also said: "So at that time, the young Yin of the capital also thought so, and there was no special direction after checking and checking, so they judged that this case was an accident." ”

But judging from the fact that the killer deliberately used oleander stems and leaves, this must have been a planned poisoning. Now the main suspicion is still on those students. Guo Xi lowered his head and said meaningfully: "Although they all have a good future, people's hearts are unpredictable." ”

Yun Pan said to Guo Xi: "I remember that during the investigation, it was said that Zhu Kexin and Zhu Zhuzhi had a very good relationship, and the two basically ate and slept together. At that time, Zhu Zhuzhi took the boiled zongzi to the canteen, called a dozen or so students who were in the canteen at the time, and after he picked a zongzi himself, Zhu Kexin happened to come in from outside, probably no zongzi, so he asked for the zongzi in Zhu Zhuzhi's hand, the two had a close relationship, and Zhu Zhuzhi handed the zongzi in his hand to Zhu Kexin. ”

Yun Pan glanced at An Ying, and continued: "Before, An Ying said that if you poison someone, you must ensure that person will eat this thing, so it is unlikely that someone from the Zhu family will be poisoned. But I think that if you push it backwards according to reason, no one can guarantee that the zongzi picked by Zhu Zhuzhi is poisonous. ”

As soon as these words came out, Guo Xi and An Ying glanced at each other, and Guo Xi's words couldn't help but be excited: "Yun Pan's words reminded me. Only Zhu Zhuzhi can guarantee that the zongzi he picks is the poisonous one! ”

Yun Pan's mind flashed, but before he could speak, Master Guo shook his head again and said, "Then how can you guarantee that Zhu Kexin will definitely eat the one in his hand?" ”

Xiao Yi also said: "Zhu Zhuzhi is the first place in the provincial city test, and he is also the victim. He won't poison his dumplings and want to poison himself. ”

An Ying also shook his head and said, "If this poison was given by Zhu Zhuzhi himself, then it would be good to explain how to ensure that he got the poisoned zongzi." However, such an inference is that Zhu Zhuzhi wants to poison Zhu Kexin, but how can he be sure that Zhu Kexin will want the zongzi in his hand?

Although the two have a good relationship, this matter of begging for zongzi in other people's hands must be an accident. Who can guarantee that Zhu Kexin will definitely ask for the zongzi in Zhu Zhuzhi's hand? If you don't want to, Zhu Zhuzhi will throw away the zongzi in his hand again, which will arouse the suspicion of others. There are so many loopholes here that there is no real evidence at all. It's all our own guess. ”

"Among these people, Yang Ye has some connections with the Criminal Department, so let's ask him first." Guo Xi closed the case file and said to An Ying and the others
