He was fat, full of energy, and deliberately raised his voice to the highest, and immediately succeeded in attracting all the eyes around him. was about to add a few words to let Zhang sneak out of a big ugly. Unexpectedly, Zhang Qian suddenly picked up two wine glasses, shook his head at him and smiled.

"If it's Brother Lu, naturally you can only use your mouth!" Unhurriedly, he poured two wine glasses, one of which was full of home-brewed chrysanthemum white, and the other one motioned to the servant to help pour water, Zhang Qian explained with a smile, "And Zhang, but he uses a weighing pan that sells medicine, two cups of the same size." The weight of alcohol is exactly 90% of that of white water! A glass of wine, how much alcohol it contains, take the same amount of white water, weigh it, and you can calculate it. You don't believe it, but take it! ”

"Clever!" Bai Yunzi Sima Chengzhen cultivates the way of immortality, dealing with pills and various measuring tools every day, and is no stranger to measuring the proportion of objects. After listening to Zhang Qian's words, he immediately realized, "In this way, if you take the wine pulp to combine the medicine in the future, you will have a reference!" is worthy of being the descendant of Qin Moyan, Xiaoyou is really knowledgeable! Such a simple way, the old man never thought of it! ”

"Clever! Brother Zhang is smart! The young talents who were deliberately attracted by Lu Xuan with a loud voice also nodded. Even if he is not good at calculation, he believes that Zhang Qian's method will definitely work.

Only Lu Xuan himself was still unconvinced, shaking his fat palms, and arguing loudly: "Clever? How is a clever method? With such a small glass, how much difference can the weight of a glass of wine and a glass of water be? How can there be such an accurate weighing pan in the world? Who can guarantee that such a light thing will be called exactly the same! ”

"If Brother Lu can't measure it, others must not be able to measure it. The weight of a glass of wine is too small, one liter, one bucket, what should you do? Zhang Qian took over the conversation unceremoniously and asked with a sneer.

For Zhang Shuo, He Zhizhang, Zhang Ruoxu and other predecessors who have glorified the history of Chinese civilization, Zhang Qian has always maintained a little respect in his heart. Therefore, even if you are criticized by your predecessors for being wrong, you will not get angry and argue. However, for Lu Xuan, who relies on the power of his own parents and is domineering, Zhang Qian is not used to the other party's idea at all, so when he seizes the opportunity, he directly tells the other party: You are a fool, please accept the reality!

"The cup I just talked about, how did it become a liter and bucket again?" Lu Xuan thought that he had caught Zhang Qian's sore foot, and shouted even louder.

"Brother Lu, you can use liters or buckets. The reason makes sense, the size of the gage is the same! I couldn't bear to watch him continue to show his ugliness, so Zhao Zixiao gently pulled his clothes and reminded him quietly.

"Nonsense, how can it be the same as a cup?!" Lu Xuan didn't know the hearts of good people, so he continued to argue with his neck, "How does it make sense?" Giving you a bucket, can you measure the weight of wine or water? ”

Seeing that this person didn't know what to do, Zhao Zixiao wanted to cry without tears, so he had to arch his hand and retreat. The other students tried to move their bodies away from this person as much as possible, lest they move too slowly and be regarded as stupid.

Since the Qin and Han dynasties, Huaxia has paid attention to a farming and reading heirloom. Therefore, most of the scholars are landlords in their families. And the landlord's family collects rent from the tenants every year, how can it not always be equipped with instruments for measuring capacity, such as liters and buckets, and a large scale for measuring weight?

As Zhao Zixiao said, as small as a glass of wine and a glass of water, it is indeed easy to make errors in measurement. It can be zoomed in to a bucket of wine and a bucket of water, and the measurement error is basically negligible. And the principle is the same as using a cup. When the weight of a bucket of wine and a bucket of water is measured, the comparison between the two compartments, combined with the standard weight of pure wine, can naturally obtain the specific essence content of the wine.

"You all know how to measure? You all believe what he says? Sensing that even the previous few people who deliberately flattered themselves were quietly staying away, Lu Xuan finally realized that he had lost his ugliness again. However, he refused to admit defeat easily, stomped his foot a few more times, and quickly changed the topic, "Even if you can measure clearly, what kind of ability is it!" After all, it's a useless crooked way! ”

"Who are you nephews and nephews, why are you talking nonsense?! Using wine and medicine to cure diseases and save people, how can it be a crooked and evil way?! Sima Chengzhen is obsessed with immortality and alchemy, and what he likes to hear the most is the words "crooked and heretical". Immediately, he was so angry that his white beard fluttered, and he pointed at Lu Xuan's nose with floating dust and scolded him sharply.

Then Lu Xuan was bent on finding trouble with Zhang Qian, where did he think that he would accidentally injure a Taoist priest? Instinctively took a few steps back, gritted his teeth and argued, "I'm not talking about your old man, I'm talking about him!" Healing diseases and saving people is the medicinal wine that your old man combined. And he, the chrysanthemum white he made, is a crooked and evil way! This thing is made from grain, and the more essence of wine it contains, the more grain it consumes when it is brewed. As a scholar, I don't want to repay Jun's grace, but I make this chrysanthemum white and take food from the mouths of the people, isn't it a crooked way, what is it? ”

This is pure nonsense, who doesn't usually drink a few sips of wine? If chrysanthemum white is taken from the mouths of the people, then what should rice wine and mash be?

Immediately, someone frowned, intending to speak up for Zhang Qian. However, for a while, I didn't know how to argue. After all, it does cost food to make alcohol. And in Datang, there are indeed many people who need to use wild vegetables and elm money every year to spend the time of green and yellow.

"Brother Lu has forgotten that this wine is still known as a heart ruler?" Just when they were so anxious that their eyes were on fire, Zhang Qian's gentle voice sounded in everyone's ears, still maintaining politeness and patience, as if he was teaching a lesson to a naughty boy, "In the eyes of stupid and stubborn people, brewing this wine is, of course, a waste of food." In the eyes of the wise man who has the world in mind, winemaking is not only a waste......"

"Don't be forceful, someone said just now, it's always a drunk, drinking rice wine, it's the same!" That Lu Xuan learned the lesson of the last time, resolutely did not give Zhang Qian room to play, grabbed the conversation, and interrupted loudly.

"But this wine can also save people's lives, you know?" Zhang Qian glanced at him disdainfully, and raised his voice by three points in an instant.

"Saving lives? Without adding any drugs, just rely on this wine? Lu Xuan was taken aback, and moved backwards with a weak heart.

Zhang said before that if the alcohol content exceeds 70%, it will cause harm to people's bodies. In the same way, for bacteria, that is, the evil poison in the mouth of the healer, alcohol is the nemesis! Zhang Qian took a step forward with a smile, condescending, like a giant looking down on a dwarf, "If someone is injured on the battlefield, cleaning the wound with a liquor containing more than seventy percent of the alcohol can reduce the chance of infection by at least eighty percent." Even if the wound has suppurated, cleaning it with this substance in time has a better chance of killing the bacteria and evil poison inside, so that the patient can turn the corner! ”

Damn, what's wrong with the liberal arts students, the little junior high school physics and chemistry in the stomach of the liberal arts students, when they get to the eighth century, they still have a crushing advantage! What's more, today Zhang is still facing an eighth-century gentleman who does not learn and does not know!

Immediately, Lu Xuan became mute. Tilting his head, he stared at a pair of overindulgent naked eye bubbles, and retreated again and again. It was as if the demon who was haunting suddenly saw the gods.

And the people around him, including Sima Chengzhen, who was the best at alchemy and dispensing, were also so shocked that they opened their mouths one by one, and they couldn't say half a word for a long time.

You know, in these years, any small wound can lead to purulent infection. And once the infection gets out of control, that is, the evil poison that doctors often say retrograde into the bloodline, it can make people lose their lives.

Looking at those who have experience in the army, including Zhang Ruoxu and Wang Han, they are even more like being struck by lightning. The face will be blue, white, red, and ever-changing.

In the war, most of the soldiers who died in battle did not die on the battlefield, but the wounds infected after the vicious battle! Therefore, any army, with more than 20% casualties, will lose its combat effectiveness. If the casualty rate exceeds forty percent, you will be dragged down by your own lottery number, and if you don't retreat in time, you will face the end of the whole army!

If the alcohol content is more than 70% chrysanthemum white, it can really reduce the chance of wound infection by 80% as Zhang Qian said. It can also kill the evil poison in the wound that has suppurated, so that the patient's chance of healing is increased by half. That, not only saved the lives of a few people, but made all the soldiers of the entire Datang Dynasty reborn!

After all, when the two armies are at war, in addition to the chief general's strategy, the most critical factor that determines victory or defeat is whether the veterans in the army have played a role.

No matter how strong the recruit's body is, due to nervousness, fear and other factors, he will move out of shape, miss the fighter, and even crash around like a headless fly. The veteran, on the other hand, knows to seize most of the opportunities to kill the opponent and protect himself!

The veterans are all new recruits.

A recruit can only become a veteran after several battles, not to die, not to be disabled.

If you can make the wound suppuration, the chance of infection is reduced by 80%......

"Yongzhao, this is true! You're really not talking nonsense to teach this idiot a lesson?! After a moment of silence, Zhang Shuo's voice was the first to sound from behind Zhang Qian, with a slight tremor and full of anticipation!

"With Zhao, you have thought clearly, the stakes are high! No kidding! "Even if he takes good care of Zhang Qian, at this time, Zhang Ruoxu didn't dare to be sloppy in the slightest, rushed over with reddened eyes, and grabbed his shoulders." A certain was once the captain of Gunzhou, and there has never been any joke in the army! ”

"Brother Zhao, you have just come out of the mountain gate. The utensils here in Datang may not be the same as those used in your mountain! Zhang Xu was the most intimate, and even found a way out for Zhang Qian, in case he held on to the end for the sake of face.

"Dao Gong, Shi Weng, Brother Bo, you don't need to doubt what Zhang just said. You should know that Zhang is not the one who believes in it! I am very grateful for everyone's concern, however, Zhang Qian did not take the opportunity to retreat, first broke free from Zhang Ruoxu's control, and then smiled and gave up to Zhang Shuo and the others, "The method of alcohol content measurement, I have just said very clearly. If I want, I can also go home and help refine the spirits up to 70%. Everyone randomly found a few domestic animals, cut their legs with knives, and then soiled the wounds in various ways, and then cleaned them with spirits containing more than 70% alcohol. ”
