Sister Li and I were both surprised that a person who was deeply trained in Western science would be so passionate about the mysterious Chinese medicine.

I seemed to think of something, and couldn't help asking: "Brother Hui, you just said that the crystals on the box are a mixture of corpse liquid and rotten wood, I see that you didn't touch it with your hands just now, and you didn't look at it much, just closed your eyes and sniffed it with your nose, did you judge it through your sense of smell?" But I didn't smell the crystals. What a special smell? ”

This time, Sister Li asked me in surprise: "How can you not smell it?" This layer of crystals does have a very special smell."

"I don't have a cold, I don't have rhinitis or anything like that, but I've never smelled anything about it," I argued with Sister Li.

Yang Hui smiled and listened to our argument, didn't say anything, just got up from the sofa, took out a bottle of crystals from a cabinet, and then walked up to me, carefully opened the bottle, and then asked me to put my nose close to the bottle, he fanned the air at the mouth of the bottle with his hand, gently fanned it in the direction of my nose a few times, and asked me if I smelled anything.

I remember that when I was in middle school, the teacher used this method to make us smell poisonous gases. But I didn't smell anything.

Yang Hui walked up to Sister Li again, used the same method to make her smell the bottle, and asked her if she smelled anything, and Sister Li's answer was yes: "It smelled, it was very strong."

I'm surprised, is there something wrong with my sense of smell?!

I knew that the reason why Yang Hui suddenly took out this bottle for us to smell must be that he was ready to explain something to us, so he didn't rush to take the initiative to ask.

Sure enough, Yang Hui put the bottle back, and then still unhurriedly did it on the sofa and started his "teaching":

"Any idea what I just sniffed you both? It is cyanide, one of the most poisonous poisons in the world. If cyanide reaches a certain concentration, it only takes 1/5000 of a second to kill a person, but don't be nervous, the concentration that I just smelled you is very small. Do you know why one person can smell this cyanide and the other can't? This is because, about 50% of people in this world are born with this ability, and this ability is inherited, just like some people can curl their tongues and others can't.

Of course, if a forensic doctor, or an ordinary person, has this ability, it is very good, and sometimes it can even save your life.

For example, in the United States, there was a famous "Halloween horror incident", on Halloween that year, someone actually mixed cyanide into candy and distributed it to others, and nine people died of poisoning. But three received the poisoned candy but did not eat it because they smelled cyanide in the candy, and one of them quickly reported the crime. These three people are the ones who have this sense of smell. ”

After listening to Yang Hui's explanation, I suddenly understood that Yang Hui and Sister Li have an innate advantage over me in terms of smell. Because they inherited the ability to smell better than mine.

I joked, and said, "It's over, if I get such poisoned candy, I'm going to die, because I don't have the smell of you two." ”

When we were done, we all laughed.

I admire this Yang Hui more and more, and I like it more and more, how can he be so knowledgeable, not only that, but also so humorous, so approachable, this is the kind of "niceguy" in English.

After talking about the sense of smell, Yang Hui suddenly thought of something and asked Sister Li and me, "Have you read the county records of our county?" ”

Sister Li and I both shook our heads again and again, county chronicles? I'm afraid it's all in classical Chinese, and we're not studying history, so why do we look at that?

The more we don't understand, the more interested Yang Hui seems to be in telling us:

"I've seen it, you don't know, in the late Ming and early Qing Dynasties, there was a strange person in our county, surnamed Gao, because he was blind, so everyone called him Gao Blind, but no one knew his real name.

Why is this tall blind man a strange man? First, although he was blind, he was indeed the most famous 'swordsman' within a radius of hundreds of miles at that time, what was a swordsman? In fact, it is the kind of person who helps people take revenge, or helps people fight, a bit like underworld elements.

is still very capable of fighting when he is blind, which shows that he is strong in martial arts, but it is not necessarily like in martial arts novels, he completely relies on hearing to judge the opponent's attack. He has a very clever strategy, only going out at night to act or fight with people, and hiding during the day. In this way, the visual advantages of normal people can be weakened.

The most surprising thing is that his sense of smell is extremely sensitive, and it is said that his sense of smell is comparable to that of a dog, so his way of understanding the world is very different from that of ordinary people, and he relies on his sense of smell to understand the world. For example, he only needs to raise his nose and smell it, and he can tell exactly what time it is. Because the 'earth atmosphere' is different at different times, even for the average person, if he is completely blindfolded, he can smell the air in midnight and daytime, and the air is different.

He relied on this special ability to become a terrifying swordsman in our area.

At that time, the Qing army had just entered the customs, the world was undecided, and the army was in chaos. As a Han Chinese, of course, he supported the Ming Dynasty, so when the Qing army occupied our area, he and seven or eight other swordsmen with strong martial arts decided to assassinate the top Qing army general of the local garrison.

On a night when they couldn't see their fingers, they went into action.

But due to various reasons, the assassination plan did not go very smoothly, they were exposed in advance and were discovered by the Qing army, after a period of desperate fighting, two swordsmen were hacked to death by the Qing army, and the remaining few swordsmen finally broke through and ran out, these swordsmen are locals, they feel that they are familiar with the terrain, and it is so dark, it should not be too difficult to escape.

But what they didn't expect was that the Manchu people were used to hunting, so they actually used hunting dogs to track down these swordsmen, and they took them as prey. It's miserable, how strong the sense of smell of the hounds is, so their olfactory tracking ability is even more amazing, no matter how the swordsmen run, how they turn, how they turn, they can't get rid of the tracking of these hounds.

From a scientific point of view, the more nervous you are and the faster you run, the stronger the smell on your body and the easier it is for the hound to track.

In the end, these swordsmen were chased by the Qing soldiers who led the hunting dogs one by one, some were hacked to death with random knives, and some were bitten to death by hunting dogs. Only the tall blind man managed to escape.

How did he escape? Why is he the only one who can escape the tracking of these hounds with an unusually sensitive sense of smell? Can you two guess? ”
