"I haven't shown this thing to anyone, even if Ancestor Yu Ji is still alive and is a genius of Tianzhong, it is unlikely that he will know."

Fox Gangzi sighed in a deep groan: "But when I arrived in Changsha, after being trapped in the city due to the war, this sour smell wafted into the air for a long time. ”

"People may not know what it is, but I can't forget it."

"Second son, since you can use this thing to kill the enemy, you must know about this thing, can you tell me what other effects this thing has?"

Sun Quan smiled, he liked this kind of diligent and studious ancients.

"Dare to ask the Taoist, can you give what you have learned in your life to the next level?"

Sun Quan said a word, and the top fox Gangzi was speechless.

Everyone in the world knows that the law cannot be passed on lightly, you are such an old person, how can you go straight to the topic as soon as you come to the door?

Why do people teach you?

"It's Xiaodao, Meng Lang."

In order to express his apology, Hu Gangzi took out another piece of silk silk in his arms, and said again: "After many days in Changsha, I learned that Sun Taishou was in urgent need of food, and this thing may be able to help one or two, I don't know, can I exchange it?" ”

Sun Quan only glanced at it, and immediately saw the "Catalogue of Gold Mines" written in small characters next to him, and Neili also recorded a lot of mountains and rivers, from Shuzhong to Jingzhou, all the way to record clearly, and also pointed out the location of several gold deposits.

With this thing, in the future, Sun Jian will be equivalent to sleeping with a sea of gold and silver, and there will never be a shortage of gold and silver!

Sun Quan forcibly endured the excitement in his heart and pushed this thing out: "It's just a mundane thing." ”

The corners of his mouth trembled with a smile, but he would not give in easily. As a time-traveler, if you come to this era and still lack money, then so many novels in your previous life will be written in vain, and it will be a shame for your peers.

Hu Gangzi suddenly realized that since Sun Quan knew that 'sulfuric acid' must be the same as himself, he disdained all mundane things, so he reached out again and took it out of his arms, one by one, and took it out, so that Sun Quan felt that there was still some unknown treasure hidden in his arms.

"The River Car Sutra", "Xuanzhu Sutra", and "Jinshi Returning Dan Technique" were taken out, and Sun Quan was completely stunned!

He thought that Hu Gangzi would come up with some secret methods for cultivating into immortals, but these were clearly medical books in front of him!

"The Book of the River Car" records the prescription of the grass river car to improve liver function, and the "Xuanzhu Sutra" has a method of improving lung function "Phlegm Pills", no wonder Hu Gangzi will be on the same road with Zhang Ji Zhang Zhongjing, it turns out that this person is not only a chemist, but also a doctor!

Zhang Ji, in the future, he is going to become a figure of the Heavenly Master, and he may not be able to win it over, but this fox Gangzi, Sun Quan will not miss it no matter what.

"That's all there is to the trail."

Fox Gangzi looked at the silk silk full of tables in front of him, and the reluctance in his heart was written on his face, these, but he had worked hard for half of his life, and he had traveled all over half of the rivers and mountains of the Han Dynasty.

Sun Quan nodded, seeing that the things on the table were motionless, and said slowly: "Sulfuric acid, which is extremely corrosive, can burn the skin after touching, and will ulcerate and become inflamed if not cared for in time. ”

"But there's more to this thing than that."

"This material can be used in smelting, agriculture, ...... It's unimaginable to be so versatile...... In fact, there are more useful things in this world than stone galls. ”

"Do you know what saltpeter is?"

Hu Gangzi nodded again and again: "Naturally I know." ”

"After the saltpeter is melted, take the clear mixed liquid and heat it to evaporate, so that it is concentrated, and then cool it in a small basin to make it condense into crystals, this thing, called potassium sulfate, this thing is buried in the ground before sowing, can add nutrients to the land, when the seedlings are not growing well, it is used for top dressing, which can reverse the defeat......"

Sun Quan's 'potassium sulfate' was also discovered by the 'fox gangzi' in front of him, and recorded in the book "Yellow Emperor Jiuding Shendan Sutra", the interesting thing is that this great chemist studied sulfuric acid and potassium sulfate but didn't know what this thing was used for!

If not, how can there be a century-old weakness of traditional civilization?

How can there be a sharp decline in population caused by a shortage of arable land?

"Ahh

As they talked, one of the wounded soldiers in the shack let out an exclamation in his sleep.

"Second son!"

The subordinates came into the shed to pray, and Sun Quan got up again and again and said, "The Taoist chief will wait a while, and then he will step out." ”

Hu Gangzi didn't know that he was waiting for him at all, and he had been waiting by Sun Quan's side for a whole life!

Sun Quan walked into the medical shed, and saw that the wound was red and swollen and pus was coming out, and at first glance he was injured by a weapon soaked in 'boiling dung soup', which could make the wound inflamed and cause fever all over the body, and finally the person was taken away by complications and fever.

"Quick, open the wound and clean it with alcohol, clean the pus, cut off the rotten flesh next to the wound until you see bright red blood flowing out, and then wrap it with allicin."

Immediately after, a simple, primitive operation appeared.

The group of soldiers took the most ordinary daggers and sterilized them with alcohol, and then went about their work.

When Hu Gangzi couldn't wait, he went over to take a look, and he watched Sun Quan's soldiers peel open the red and swollen wounds on the wounded man's arms, and then squeeze out the pus from the wounds, and then pour in the wine-scented wound to clean the wound, and cut off the festering skin with a dagger.

In the process, five or six strong men barely held down the wounded who were tied to the bed board, and the whole medical shed howled like pigs one after another.

When it was all over, the patient was lying on the bed with collapsed body, his clothes and hair soaked with sweat, and he didn't even see the soldiers who had stitched up his wounds with needles and threads, as if a needle had been pricked into the flesh.

Fox Gangzi could be said to have watched the wound on the injured man's arm be stitched together, and he remembered another person for this miraculous skill, who was extremely good at this.

"Does the second son know Hua Tuo?"

Sun Quan shook his head: "I don't know." "He really thinks about Hua Tuo, if there is 'hemp boiling', how much manpower will have to be saved.

"Then where did you learn this medical skill of cutting flesh to heal wounds, and the magic technique of sewing wounds?"

Sun Quan pointed to the side: "The dead man forced it out." ”

Fox Gangzi looked out along the medical shed, and there were several dead people in armor lying there, each of whom was seriously injured, and some even injured important parts, and there was no time to treat them.

Seeing this, Hu Gangzi said to himself: "Isn't this chaotic world that forced out a human holy hand? ”

"Second son, what was the wine-scented liquid that was poured into the wound at the beginning?"

"Alcohol." Sun Quan thought for a while and said, "But don't talk about it...... outside."

"Fox Hill will never leak secrets."

"That's not what I mean, I mean, alcohol needs to be distilled, and if the pressure generated by distillation is not well controlled, it will cause an explosion, and it will hurt others and yourself at that time, so learning art and getting fine, just like this sulfuric acid, if you don't know it, reach out and touch it, it will be easy to be burned......"

Hearing this, Hu Gangzi hurriedly hid his hand behind him, and said with a wry smile: "What the second son said is extremely true. ”
