Lin Qingyuan called the servant to find a puppy, broke up the half of the steamed bun and poured it into the puppy's belly, and also poured the remaining porridge and pickles into the poor puppy, and as a result, the puppy barked. Pen "Fun" Pavilion www.biquge.info

When they fed the puppy the water in the porcelain bowl again, the puppy ate the half of the steamed buns and pickles that were dry and hard, and was thirsty, and the bowl of water was drunk without being filled.

After waiting for a long time, the puppy was still barking and wagging its tail around the house, nothing happened. It seems that there is no poison in the food.

Xie Bing and Lin Qingyuan were a little disappointed, shook their heads and were about to leave the room, at this time, Bai Zhiruo, who had gone to visit the Zhong family, happened to come back, and she who was standing at the door suddenly snorted at the door, pointed to the bed and shouted, "Look, what is that?" ”

Lin Qingyuan and Xie Bing looked back in the direction of Bai Zhiruodi's finger, and saw that something was shining under the bed. Lin Qingyuan bent down and took a closer look at it first, it seemed to be a small porcelain bottle. Reaching in and taking out the porcelain bottle, he unscrewed the lid and looked at it, and there was a small half-bottle of semi-solid stuff inside.

He put the small porcelain bottle in front of his nose and sniffed it, and then a smile appeared on the corner of his mouth, but he didn't expect the man's wife to make a meritorious contribution this time, and actually found the most important physical evidence, arsenic!

He laughed and said, "I have a bad temper, but my eyes are good." The disgruntled Bai Zhiruo reciprocated with a big white eye.

Lin Qingyuan judged that since no signs of poisoning were found in Gu Haichen's food, the only chance for this arsenic to be poisoned was in the decoction he drank. And the decoction he drank was all boiled by his mother Zhong, even if others wanted to take the opportunity to poison it, it had to be without Zhong's knowledge.

Lin Qingyuan turned back to the backyard and found the medicine jar on the ground, then reached out and probed inside, and sure enough, there was arsenic slag remaining at the bottom of the jar. It seems that the poison was indeed put in the decoction.

Judging from the clues, there are two possibilities: one is that this Gu Haichen has been studying in the academy all the year round, and he may have been poisoned when he came from home. Another possibility is that he offended someone in the academy, and then in order to take revenge, that person secretly went to Gu Haichen's house and poisoned the decoction that Gu Haichen usually drank.

However, according to the proof of Mr. Zheng of the school, Gu Haichen has always been a loner in the school, has a very introverted personality, is silent every day, and has almost no friends. If you have to count friends, there is only Du Hongshu who studied hard with his classmates, that is, the scholar who informed Xie Bing during the assessment in the Lin Mansion that day.

From this point of view, the biggest possibility is the former, Gu Haichen has been poisoned after drinking medicine at home. But the latter is not out of the question, and the more introverted people are, the more likely they are to make surprising moves.

So who poisoned it? Judging by all indications, the person who lived in the school and his mother and wife were suspicious.

Lin Qingyuan asked Xie Bing to send officials to bring all the people in the academy to the backyard for interrogation, counting about a dozen people. They are all scholars who have no power to tie the chicken, and their legs will be weak when they see the tolerance, and when they hear the rumors from the yamen, how dare they say half a word.

Lin Qingyuan and Xie Bing called these people to the courtyard one by one to inquire, and Lin Qingyuan also asked Bai Zhiruo to invite the old lady over, after all, Zhizi is better than his mother.

These people include Mr. Zheng and his students, running the hall, doing miscellaneous things, and so on. I asked them all one by one, but I didn't find any clues.

After interrogation, it was found that in the eyes of everyone, this Lu Xueru was purely pedantic, and he did not go out of the gate of the school every day, except for the time when he went out to take the exam. Shaking his head and reading in his room all day long. As soon as you go out, you have to lock the door, even when you go to the thatched house.

Lin Qingyuan pondered for a while, and suddenly asked Zhong, "Mother Gu, is there any medicine left over from the decoction that Gu Haichen drank?" ”

The old lady had not yet come out of the pain of losing her child, wiped away her old tears and nodded: "Yes, there are two packs." Right under my bed. ”

"Brother Xie, you quickly send someone to fetch those two packs of medicine." He said. Xie Bing didn't know what Lin Qingyuan's intentions were, but since he did this, it must be reasonable, and he trusted Lin Qingyuan unconditionally.

When the official took the medicinal materials, Lin Qingyuan hurriedly took it and opened the package and looked through it carefully. Suddenly, his eyes lit up, and then he handed the medicinal herbs to the servant.

Lin Qingyuan whispered a few words in Xie Bing's ear, Xie Bing nodded, and said to everyone: "Okay, I'll ask here today, you all go back." ”

Suddenly, the people in the courtyard were relieved and rushed to Gu Haichen's house, as if they were afraid of being infected with bad luck.

Lin Qingyuan and the three of them said goodbye to Gu Haichen's mother and wife, and took the officials out of the courtyard.

After returning to the yamen, Lin Qingyuan also brought the puppy back, and after feeding the puppy with the medicinal herbs brought back by his servant, after a while, the puppy began to twitch, and white foam kept coming out of his mouth, Lin Qingyuan hurriedly flushed the salt water and poured it into the puppy, and after a while, the puppy gradually eased up, coughing and coughing, and it was considered to have picked up a life.

Bai Zhiruo and Xie were both surprised: "This medicine is poisonous!" ”

Lin Qingyuan groaned: "This arsenic cream is not very strong, a pack of medicine can barely poison a puppy, but it is difficult to poison it immediately." Therefore, the murderer should have prepared to pretend to be Gu Haichen's mother, poisoning every packet of the decoction he usually drinks, and as he drank the medicine more and more, he poisoned Gu Haichen little by little. In this way, even if the East Window incident happens, he will be able to get rid of suspicion, and it is logical to let Gu Haichen's mother bear the charge of poisoning and murder. ”

Bai Zhiruo gritted her teeth and said angrily: "It's really hateful that there are such scorpion-hearted people in this world!" ”

Xie Bing said steadily: "From this point of view, this person is also very scheming, and it must not be easy to come up with such a poisonous plan." ”

"Yes, but unfortunately, it met me." Lin Qingyuan sneered.

"Then let's go to Gu Haichen's house again tomorrow?" Xie Bing looked at the sky and proposed to go again the next day. Lin Qingyuan objected: "No, we don't need to be in a hurry, now we should be in a hurry." ”

Xie Bing was taken aback and said, "Brother Lin, do you mean you know who the murderer is?" ”

Lin Qingyuan smiled and asked, "Brother Xie, have you forgotten what I put in the Haichen family?" ”

"That little porcelain vase!" Xie Bin thought about it and suddenly shouted.

He nodded and said, "That's right, once the murderer knew that the poisoning of Gu Haichen was discovered, the first thing he thought of was to destroy the evidence, and the small porcelain bottle containing arsenic was undoubtedly the most important evidence." So what we have to do now is to wait for the murderer to fall into the net! After he finished speaking, he once again showed his own confident smile.
