He was fat and had enough energy. He deliberately raised his voice to the highest level, and he immediately successfully attracted all the gazes around him. He was about to add a few words to make Zhang Qian look ugly. However, Zhang Qian suddenly picked up two wine glasses, shook his head and smiled at him.

"If it's Brother Lu, you can only taste it with your mouth!" Unhurriedly, he poured two wine glasses, one of which was filled with the white chrysanthemums from his home brew, and the other one signaled the servant to help pour clean water. Zhang Qian explained with a smile, "And Zhang, using a scale plate for selling medicine, two cups of the same size. The weight of alcohol is exactly 80% of the white water! A glass of wine contains, takes the same amount of white water, weighs the weight, and can be calculated. If you don't believe it, just take it to weigh it!"

"Great!" Bai Yunzi Sima Chengzhen practiced the way of immortality, dealing with elixirs and various measuring tools every day, and was no stranger to calculating the proportion of objects. After hearing Zhang Qian's words, he immediately realized, "In this way, if you take the wine and medicine in the future, you will have a reference object! I am worthy of being the direct descendant of Qin Mo. My friend is indeed very knowledgeable! I never thought of such a simple method!"

"Gaoming! Brother Zhang is smart!" The young talents who were deliberately attracted by Lu Xun's loud voice also nodded. Even if they were not good at calculating, they believed that Zhang Qian's method would definitely work.

Only Lu Xun himself was still dissatisfied and shook his fat palms and quibbled loudly: "Gaoming? Why is a clever method? The cup is so small, how much weight can a glass of wine and a glass of water be different? How can there be such a accurate scale in the world? Who can guarantee that such a light thing is correct!"

"Brother Lu can't measure it correctly, but others will definitely not measure it accurately. If you think the weight of a glass of wine is small, one liter or one dou, what should you do?" Zhang Qian took the conversation without hesitation and asked with a sneer.

Zhang Qian always maintained a little respect for Zhang Shuo, He Zhizhang, Zhang Ruoxu and other seniors who once shined the history of Chinese civilization. Therefore, even if they were criticized by their predecessors, they would not be angry or argue. However, for Lu Hua, a playboy who relied on the power of his elders, who was domineering the other party at all, he had no idea of ​​spoiling the other party. Therefore, when you seize the opportunity, you will tell the other party directly: You are a fool, please accept the reality!

"Why did the cup I just said become Shenghe Dou again?" Lu Xun thought he had caught Zhang Qian's painful foot and shouted louder.

"Brother Lu, you can use Sheng or Dou. The reason is clear, the size of the measuring gauge is the same!" I really couldn't bear to watch him continue to show his bad luck, Zhao Zixiao gently pulled his clothes and quietly reminded him.

"No, how can Sheng and Dou be the same as a cup?!" Lu Xun didn't know the good people's hearts and continued to argue with his neck, "How is the truth understood? Give you a Dou, can you measure the weight of wine or water?"

Seeing that this person had no idea of ​​his own good, Zhao Zixiao wanted to cry without tears, so he had to bow and retreat embarrassedly. While the other students tried their best to move their bodies farther away from this person, for fear that they would be treated as idiots.

Since the Qin and Han dynasties, China has been focusing on farming and studying and passing on the family. Therefore, most scholars are landlords in their families. And the landlords collect rent from tenants every year, so how can they not always have equipment such as raising and buckets to measure capacity, and weight measurement?

As Zhao Zixiao said, as small as a cup of wine and a cup of water, errors are indeed easy to measure. If it can be enlarged to a bucket of wine and a bucket of water, the measurement error can be basically ignored. The reason is the same as using a cup. When the weight of a bucket of wine and a bucket of water is measured, the two sides can be compared, and combined with the standard weight of pure wine, the specific essence content of the wine can naturally be obtained.

"You all know how to test it? Do you all believe what he said?" Seeing that even the previous few people who deliberately pleased him were quietly away, Lu Xu finally realized that he had lost his ugly head. However, he refused to give in easily, stamped his feet a few more times, and quickly changed the topic, "It's just that he can measure it clearly, so what's the ability! After all, it's a useless evil way!"

"Whose nephew is you? Why are you talking nonsense?! Using alcohol and medicine to cure diseases and save people, how is it a wrong way?!" Sima Chengzhen was obsessed with immortality and alchemy. The thing he didn't like to hear the most was the four words "the wrong way". Immediately, he was so angry that his white beard drifted, and pointed at Lu Hua's nose with floating dust and scolded him sternly.

Lu Xun was determined to cause trouble for Zhang Qian, but he didn't expect that he would accidentally hurt a Taoist priest? Instinctively took a few steps back and gritted his teeth and argued, "I'm not talking about you, but he is talking about him! Treating diseases and saving people is the medicinal wine combined with you. And the white chrysanthemums he made is a crooked way! This thing is brewed from grain, and the more essence of the wine it contains, the more grain it consumes when brewing. As a scholar, he doesn't want to repay the kindness of yours, but he makes the white chrysanthemums and snatch food from the people. It's not a crooked way, so what?"

This is pure nonsense. Who doesn’t usually drink a few sips of wine? If the white chrysanthemums are snatching food from the people, what should rice wine and fermented glutinous rice be?

Immediately, someone frowned and planned to speak up for Zhang Qian. However, for a while, he didn't know how to defend himself. After all, brewing wine did consume food. In the Tang Dynasty, there were indeed many people who needed to spend the time with wild vegetables and elm money every year.

"Brother Lu has forgotten that this wine is also called the measure of the heart?" Just as his eyes were so anxious that his eyes were on fire, Zhang Qian's gentle voice sounded in everyone's ears, and he still maintained politeness and patience, as if he was teaching a naughty boy. "In the eyes of stupid and naughty people, brewing this wine is of course a waste of food in vain. In the eyes of wise men who care about the world, brewing wine is not just a waste..."

"Don't make sense. Someone said just now. In short, it's the same if you are drunk and drink yellow wine!" Lu Xun learned from the lesson last time, resolutely refused to give Zhang Qian room to play, snatched the conversation, and interrupted loudly.

"But this wine can save lives, do you know?" Zhang Qian glanced at him disdainfully, and instantly raised his voice by three points.

"Save life? If you don't add any medicine, just drink it?" Lu Xun was shocked and moved back guiltily.

"Zhang said before that alcohol content exceeds 70% will cause harm to the human body. Similarly, for bacteria, that is, the evil poison in the mouth of doctors, alcohol is the nemesis!" Zhang Qian smiled and took a step forward, condescendingly, like a giant looking down at the dwarf. "If someone is injured on the battlefield, cleaning the wound with more than 70% alcohol can reduce the chance of infection by at least 80%. Even if the wound has become suppurated, use this object to clean it in time, and there is a half chance to kill the bacteria and evil poison inside, so that the patient can be safe!"

Damn, what's wrong with liberal arts students? The little bit of junior high school physics and chemistry in the liberal arts students' belly still has a crushing advantage in the eighth century! What's more, today Zhang is facing a ignorant playboy who is ignorant in the eighth century!

Immediately, Lu Zhang turned into a mute. He raised his head, widened his eyes with excessive indulgence, and retreated repeatedly. It seemed that the demon who was causing trouble suddenly saw the god.

The people around, including Sima Chengzhen, who is best at refining elixirs and prescriptions, were also shocked to open their mouths one by one. After a while, they could not say a word.

You should know that these days, any small wound may lead to suppuration infection. Once the infection is out of control, which is what doctors often say, evil poisons go backwards into the blood vessels, it can cause life to be lost.

Looking at those who have experience in the ranks, including Zhang Ruoxu and Wang Han, they are even more like being struck by lightning. Their faces are sometimes blue, sometimes white, sometimes red, and ever-changing.

During the war, most of the soldiers who died did not die on the battlefield, but were infected with the wounds after the fierce battle! Therefore, any army, if more than 20% of the casualties, will lose its combat effectiveness. If the casualties rate exceeds 40%, it will be dragged down by its own lottery number. If it does not retreat in time, it will face the end of annihilation of the entire army!

If the chrysanthemum with an alcohol content of more than 70% is really as Zhang Qian said, it can reduce the chance of wound infection by 80%. It can also kill the evil poison in the already purified wound and increase the patient's chance of recovery by half. Then, it will not only save the lives of a few people, but also allow all the soldiers of the Tang Dynasty to be reborn!

After all, when the two armies are fighting, the most critical factor that decides the winner and lose, in addition to the main general's strategy, is whether the veterans in the army play a role.

No matter how strong the new recruits are, they will move out of shape due to factors such as nervousness and fear, miss out on the fighter's chances, and even bump around like headless flies. However, the veterans know to seize most of the opportunities to kill their opponents and protect themselves!

All veterans are transformed by new soldiers.

Only if a new recruit fights a few battles, he will not die or be disabled can he become a veteran.

If the risk of suppuration and infection in the wound can be reduced by 80%...

"To use Zhao, take this seriously! You are really not talking nonsense to teach this idiot a lesson?!" After a moment of silence, Zhang's voice was the first to ring behind Zhang Qian, with a slight tremor and full of expectations!

"Use Zhao, you think it clearly, it's important! You can't joke!" Even though you took good care of Zhang Qian, Zhang Ruoxu did not dare to be careless at this time. He rushed over with his red eyes and moved his shoulders. "I used to be the commander of Gunzhou, and there has never been any jokes in the army!"

"Brother Zhao, you have just left the mountain gate. The artifacts on the Tang Dynasty may be different from those you use in the mountains!" Zhang Xu was the most considerate and even found a way out for Zhang Qian to prevent him from holding on to the end for the sake of face.

"Daogong, Shiweng, Brother Bo Gao, you don't need to doubt what Zhang said just now. You should know that Zhang is not the kind-hearted person!" He was very grateful for everyone's concern, but Zhang Qian did not take the opportunity to retreat. He first broke free from Zhang Ruoxu's control, and then bowed to Zhang and others with a smile, "I have already explained the method of measuring alcohol content very clearly. If necessary, I can also go home to help refine strong alcohol with a content of 70%. Everyone just found a few domestic animals, cut their legs with a knife, and then dirty the wounds in various ways, and then cleaned them with strong alcohol containing more than 70% of the alcohol content. After five days, it will naturally verify that what Zhang said is true!"
