Zhou Fengshan and Du Chenghu took a closer look and found that Lin Jiangbei was holding a broken leaf in his hand. Before Zhou Fengshan could react, Du Chenghu had already opened his mouth in confusion: "Jiangbei, isn't this a chili pepper leaf?" Wang Longfei was killed by it? Can't you? In the past, when boiling chili water, there would be some chili leaves in it! ”

When the torture personnel in the torture room boil chili water, they need to consume a large amount of dried chili peppers, and naturally they will not be like housewives who buy vegetables carefully, but buy them in whole sacks, which will inevitably be mixed with some dried chili leaves. When boiling chili water, they are also holding a sack and pouring it directly into a large iron pot, and the torturers will not pick out these chili leaves mixed in it like cooking rice and vegetables.

As the stationmaster of Hangcheng Station, Du Chenghu has also personally observed the torturers boiling chili water, so he naturally knows the situation clearly. So at this time, when he saw Lin Jiangbei holding this broken leaf in his hand, he subconsciously thought that it was a chili leaf.

Hearing the stationmaster standing on his side, Xu Zhiji glanced at Du Chenghu gratefully, but said nothing in his mouth. Anyway, the stationmaster who should say it has said it, and if you say it yourself, you will be suspected of adding to it!

"It's not a chili leaf," Lin Jiangbei shook his head slowly and said, "This is an oleander leaf." ”

Oleander leaves?

Du Chenghu and Zhou Fengshan met a look, and hurriedly went up to watch carefully, but they looked at it for a long time, and they didn't see any doorway, I don't know how Lin Jiangbei judged that it was an oleander leaf from this leaf that was broken into an irregular shape.

Although Lin Jiangbei finally judged that it was oleander leaves from the taste of broken leaves, it did not mean that it was impossible to distinguish the difference between it and chili leaves from other aspects.

Lin Jiangbei leaned over and took out a broken leaf from the big iron pot and handed it to Zhou Fengshan and Du Chenghu for them to observe.

"Principal Zhou, Inspector General, you see, this broken leaf is a real chili leaf. Compared with the oleander leaves in the hands of the students, the crushed leaves of the pepper are significantly thinner, and the veins are richer. Looking at this oleander leaf, not only is it obviously thicker than the broken leaves of the pepper, but there is no leaf vein pattern except for a straight leaf vein in the center, and the leaf surface is smoother than the pepper leaf here! ”

After Lin Jiangbei's prompt, Zhou Fengshan and Du Chenghu both saw it, and sure enough, the broken leaf that Lin Jiangbei took out of the iron pot earlier was very different from the crushed pepper leaf behind.

At this time, Chen Haitao also reacted and said to Gu Siqiang: "Aren't there two oleanders in the yard?" Go down there and pick up two dried leaves and come back! ”

"Yes!" Gu Siqiang responded, and hurriedly ran outside, and two minutes later, he ran back from outside, holding seven or eight dried oleander leaves in his hands.

Lin Jiangbei stretched out his hand and took a dried leaf from Gu Siqiang's hand, gently crushed it with his hand, picked out two fragments, handed them to Zhou Fengshan and Du Chenghu respectively, and said, "Principal Zhou, Inspector General, compare it, is this broken leaf of oleander exactly the same as this broken leaf in the student's hand?" ”

Zhou Fengshan compared it with Du Chenghu, and indeed, the two broken leaves in their hands were exactly the same except that the shape was different from the broken leaf that Lin Jiangbei picked out from the big iron pot.

What Lin Jiangbei took out of the iron pot was indeed oleander leaves!

It's just that Zhou Fengshan had another question in his heart at this time.

"Jiangbei, can oleander leaves be mixed with chili water, can it kill people?" He said: "How do I remember that oleander leaves are a medicinal herb? When I was studying in Nanjing, a classmate had a toothache, and a Lang Zhong wrote him a home remedy and asked him to find an oleander leaf to bite with his teeth, and he did so, and then his teeth really didn't hurt. I haven't seen anything happen to him since then! ”

"Principal Zhou," Lin Jiangbei smiled bitterly, "It's because your classmate has a big life, and he just bites it with his teeth, and he doesn't absorb much of the toxic ingredients in oleander leaves." ”

After a pause, Lin Jiangbei said again, "Regarding the treatment of toothache in oleander leaves, it is because oleander leaves contain a substance called oleander acid, which can inhibit the enzymes produced by caries bacteria and prevent sugar and protein from precipitating on the teeth to form plaque. Therefore, it has a certain effect on the treatment of dental caries. ”

"It's just that oleander acid is a substance that is not only contained in oleander leaves, but also in foods such as jujubes, so there is no need to risk using oleander leaves in order to treat tooth decay."

"And students can be sure that your classmate doesn't seem to have anything wrong on the surface. But the heart must have been damaged, but it wasn't visible at the time. ”

"Huh? It seems like yes! Zhou Fengshan suddenly realized, "The last time I went to Nanjing, I also visited my classmate, who did have heart problems, and drank Chinese medicine every day to recuperate." At that time, I was still wondering how he was young, thirty-seven or eighteen years old, had a problem with his heart. It turned out to be related to the fact that he used oleander leaves to treat toothache! ”

"It should be!" Lin Jiangbei nodded and said, "Oleander, also known as willow leaf peach, is poisonous, contains cardiac toxic glycosides, oleander leaves have the same effect as digitalis, and only the amount of a penny can make people die." ”

"And how much does a penny weigh?" Lin Jiangbei took three dried oleander leaves from Gu Siqiang's hand and said, "Three dried leaves!" ”

Zhou Fengshan and Du Chenghu were dumbfounded, they didn't expect that the commonplace oleander leaves had such great power, and just three pieces could kill people......

In the Republic of China, one pound was equal to sixteen taels, and one tael was equal to ten yuan, which was converted into the current unit, and one coin in the Republic of China was about 3.72 grams. According to modern textbooks, three grams of oleander leaves are enough to kill people, and Lin Jiangbei's statement is only shrunk and not exaggerated.

"And how many oleander leaves are in this big iron pot?" Lin Jiangbei turned around and rummaged in the big iron pot, and in just over a minute, he found dozens of broken leaves from the big iron pot, he pointed to these broken leaves and said, "These broken leaves found by the students alone can spell out at least fifteen or sixteen complete oleander leaves, that is to say, the water boiled out of these leaves is enough to kill five or six Wang Longfei." ”

Speaking of this, Lin Jiangbei turned to look at Xu Zhiji, "Should you explain now, where do the oleander leaves in this pot come from?" ”
