Song Yuner blushed and asked in confusion: "What's wrong with this leaf? Why can't you touch it? Can this leaf still eat me?"

"That's right, this leaf can be eaten for you!" Yang Qiuchi didn't have a smile on his face, and he raised the leaf and looked at it, "This is the leaf of oleander, it's poisonous!"

Ah? Song Yuner was startled and quickly threw away the branch in her hand. She asked with lingering fear: "Brother, you might have scared me, right?" She looked stern and glared at her almond eyes: "If you dare to scare me, hum!"

Yang Qiuchi didn't say anything, but still stared at the oleander leaves in his hand in a daze, and then looked around. He saw that the mountains and fields were full of oleanders. It can be imagined that in the spring and summer blossom season, the flowers of the oleander all over the mountains and fields were blooming. How beautiful it would be.

But Yang Qiuchi is not available to imagine that kind of beauty now, because he discovered a very serious problem. He turned around and asked Mirizheng behind him: "Why are there so many oleanders on this mountain?"

Mirimatsu also looked up and said, "Wild, when spring and summer come, the mountains are full of oleander flowers, red, yellow, white, and very beautiful."

Yang Qiuchi looked back and forth, and saw that the few small wooden houses on the hillside of Mrs. Wang had turned into a few small black dots. He pondered slightly and said, "We made a mistake, go back immediately!"

Hu Jiang behind him was stunned and asked, "Young Master Yang, what did you make a mistake?"

"Let's talk about it, and I'll go back to Mrs. Wang's house immediately." After that, he turned around and walked up the mountain. Seeing that Yang Qiuchi looked solemn, it didn't seem like a joke, Hu Jiang and others turned around and walked up the mountain.

When Mrs. Wang and her family saw Yang Qiuchi and others return, they were a little surprised and nervous, not knowing what had happened.

Yang Qiuchi went directly to the room where honey was stored and asked the detective to catch another duck. He shoveled a lump of honey from a porcelain bowl next to the porcelain bowl containing honey that Hu Jiang had just inspected.

Although the duck was fine, it started to wilt, and was a little unsteady, so it fell and got up again. Yang Qiuchi shoveled another lump of honey to feed the duck, and two lumps were continuous. This time the duck barely supported it for a while before he fell to the ground and died with convulsions.

Hu Jiang and others were very surprised. Is this honey really poisonous? I found another duck, shoveled honey from another porcelain bowl and fed it. After feeding two large lumps in a row, the duck sustained an incense stick of time and twitched to death.

After almost all the ducks from Mrs. Wang’s house were tested, we confirmed that six of the eight porcelain bowls had poisonous honey.

Hu Jiang asked Mrs. Wang what was going on? Mrs. Wang and her son and daughter-in-law were already scared. I don’t know why this happened. They have been keeping beekeepers for several years. Nothing happened before. Now they have seen the ducks die after eating honey. How can they explain it clearly?

Hu Jiang waved his hand and wanted the yamen runners to come forward to catch people again. Yang Qiuchi waved his hand and stopped him. He said, "No need to catch them. No matter what their business is, they don't know that the honey is poisonous."

Hu Jiang looked at Yang Qiuchi in confusion. Yang Qiuchi pointed to the two toxic porcelain bottles in front of him and asked Mrs. Wang: "These two porcelain bottles are the honey that is collected from the ground after September (lunar calendar) this year?"

Old Mrs. Wang’s daughter-in-law asked in surprise: “Yes, sir, how do you know?”

Yang Qiuchi did not answer, and pointed to the remaining six porcelain bowls with a serious expression and said, "The honey in these six porcelain bowls should be the honey picked before August this year, right?"

Old Mrs. Wang was even more surprised and nodded, "Yes, sir, you are right."

Song Yuner was very surprised and looked at Yang Qiuchi in surprise and asked, "Brother, have you ever raised bees before?"

Yang Qiuchi shook his head, sighed and said, "The real murderer who killed Lu Xueru has been found."

Hu Jiang asked Yang Qiuchi in surprise: "It's this old lady Wang's family, right?"

Yang Qiuchi shook his head again: "No, the murderer who poisoned Lu Xueru was not a human."

This sentence "The murderer is not a human" scared everyone, and even reminded Song Yuner of the murder of Bai Xiaomei in Yunya Mountain. Yang Qiuchi also said that Bai Xiaomei's ghost killed people. She suddenly felt a chill on her back. She looked around and shivered, and asked, "Is it a ghost who is tying another poisonous move?"

"Look at your courage," Yang Qiuchi cursed lovingly, "It's not the ghost that poisons it, but the bees!"

"What?" This sentence confused everyone. Song Yuner asked in surprise: "Bees? How do bees poison and kill people?"

Yang Qiuchi didn't keep it a secret and said to Song Yuner: "Have you noticed that there are many oleanders growing all over the mountains and fields nearby. The whole plant of this embroidered peach is poisonous, with leaves, branches, and seeds all poisonous, and even its beautiful petals and stamens. The bees in the old lady Wang collect honey from the stamens of this oleander, so the honey collected is poisonous."

Old Mrs. Wang’s daughter-in-law argued: “Then, why are the honey in other porcelain bowls in our family not poisonous?”

"The flowering period of oleander is from May to August (lunar calendar). After August, the flowers have already faded. The bees cannot collect poisonous oleander honey. The honey collected from other non-toxic flowers is of course not poisonous. The honey in the two porcelain bowls behind them was collected later, so it is not poisonous."

Hu Jiang and others understood it now. After a long time of work, it turned out that the bee poisoned and killed Lu Xueru. It was really impossible for people to think about it.

Yang Qiuchi asked Mrs. Wang's son to recall when Mrs. Fan, the wife of Mrs. Naru, in Nanshao Village, bought honey with him.

Mr. Lu seems to be very famous in Nanshao Village. He was an old scholar who failed the exam in his fifties and married a wife and a concubine, but his family was in a bad state. It was difficult not to become famous. Mrs. Wang’s son went down the mountain every month to sell honey, so he immediately recalled that Fan bought honey with him around the Double Ninth Festival in September. This is consistent with Fan’s statement. In this way, Fan also bought poisonous honey.

Hu Jiang thought that since it was poisoned by bees, there was nothing we could do. We couldn't catch a few bees and went back to submit the service. The old lady Wang's family didn't know that the nectar collected by the bees was poisonous and was an accident. It was not appropriate to catch them. After thinking about it, they decided to take a porcelain bottle to put some poisonous honey and take it back to submit the case.

Hu Jiang was looking for honey in porcelain bottles, but Yang Qiuchi stared at the honey again.

Song Yuner saw Yang Qiuchi squatting there and staring at the honey in the porcelain bowls. She patted him on the shoulder: "Brother, why are you still stupid? The case has been solved. Let's go down the mountain and go back to sleep. If you haven't slept all night, you will be sleepy."

Yang Qiuchi frowned and waved his hand: "No!"

"What's wrong?" Song Yuner asked.

"This case is wrong! The bees are not the murderer. Lu Xueru did not die after eating poisonous honey."

When Hu Jiang heard this, he asked in surprise: "Young Master Yang. What did you say? Didn't you say it just now..."

Yang Qiuchi interrupted him: "I was wrong before," pointed to the honey in the honey jar and said: "Look, these poisonous honeys are almost sold. Since this honey can poison Lu Xueru and others, why haven't you heard of eating honey killing people?" He turned around and asked Milizheng: "Have anyone died in the village in the past two years?"

Li Zheng shook his head: "No." After thinking about it, he said, "This old lady Wang's honey is very good. Many families in the village buy their honey. I have bought them, but it's nothing to do after eating them. They have also sold them in the neighboring village, but they have never heard of anyone who has eaten their honey and died."

Tongzong Hu Jiang asked, "Then the duck died after eating it, so what explanation is it?"

Miri was scratching her head: "This, this..."

Yang Qiuchi said: "This is easy to explain. It is not that eating poisonous things will cause death. It is necessary to reach the amount of poisoning. Moreover, different individuals and different physical conditions will affect whether they are poisoned. Adults may not be poisoned after eating the same dose, but children may be poisoned after eating it. Children are fine, ducks may be poisoned after eating it."

Song Yuner understood a little and said, "Brother, do you mean that the dose of honey poisoning is not enough to poison people, but it can kill ducks?"

"Smart!" Yang Qiuchi praised.

Song Yuner laughed.

Miri was just finding another question and asked: "The baby is about the same size as a duck. Why haven't I heard that the baby died after eating honey?"

Yang Qiuchi was stunned. He had never thought about this problem and said, "Maybe, maybe it is related to the dosage of swallowing at one time. The baby eats less, pick a little with the head of chopsticks to drink it. But just now we fed two large pieces of duck with this poisonous honey, which is enough for a baby to eat for many days. The dose is very small every day." He pointed to the duck and said, "Besides, no matter how small the baby is, it is bigger than this duck."

Old Mrs. Wang interrupted and said, "Baby cannot feed honey."

"Why?" Yang Qiuchi and Miri asked strangely.

"A child who has not been weaned will cry constantly after eating honey, and the crying sound is weak and he is unable to eat milk. If babies eat too much honey, they will die. So we will remind you when selling honey."

Mrs. Wang’s statement is correct. According to modern medical tests, soil and dust often contain bacteria called "botulinum toxin". When bees use pollen to make honey, they may bring the contaminated pollen and honey back to the beehive. The trace amount of toxins contained in this honey is fine after eating them, but babies will be poisoned or even die. Therefore, babies under one year old cannot feed honey.

This baby cannot eat honey, and Yang Qiuchi doesn't know to be honest. In modern society, he doesn't even have a girlfriend, and he doesn't have the chance to have a child, so he doesn't care about these issues. Now, after listening to Mrs. Wang's words, he has gained knowledge.

Seeing that Song Yuner, Hu Jiang and others were still a little unbelievable that their conclusion that poisoning ducks might not necessarily kill people, Yang Qiuchi was too lazy to explain, so he said to Nangong Xiong: "You take two people to Mrs. Wang's pigpen to lead a pig out, and it costs more than 100 kilograms."

Nangong Xiong agreed, and did not call anyone else. He entered the pigpen alone, and the pig screamed suddenly. After a moment, Nangong Xiong hugged a fat pig. The fat pig was about the same size as him. Nangong Xiong was really strong. The pig was hugged by him with both hands, and he could not move at all except humming in his nose.

Yang Qiuchi asked a detective to shovel two large pieces of poisonous honey to feed the fat pig, and then put the fat pig back into the pigpen. Everyone waited around the pigpen for a long time, but the fat pig still whispered and shook his head and lived well, without any symptoms of poisoning.

Hu Jiang and others believed it now. They were also two big lumps of honey, but the duck was poisoned but failed to poison the fat pig. It seems that Yang Qiuchi said that poisoning people requires a certain dose, which is correct.

Since this fat pig is poisoned by honey, of course it is not poisoned by Lu Xueru. Besides, the duck was poisoned by two large pieces of honey in succession, while Lu Xueru just used honey to apply oral ulcers, one was taken internally and the other was used externally. The dose of toxic honey absorbed by Lu Xueru's body was even smaller, so it was even less likely to be poisoned by this toxic honey.

Yang Qiuchi was in a daze just now and discovered this problem.
