On that day, when the sun went down, Wang Han looked at the translucent layered oily liquid in the clay pot, and exhaled deeply, glycerin was finally made......

"This is my son's lifesaver?"

Lin Hong frowned and stared at the glycerin that Wang Han had taken off, and looked at him with a puzzled expression, indicating that he couldn't understand it. Pen % fun % Pavilion www.biquge.info

"It's glycerin."

"What is glycerin?"

Lin Hong's old face was a little uneasy, because he didn't understand, this was not the point, the point was that he felt that he was despised by a junior, and the despised body was incomplete......

Wang Han shook his head with a smile and said, "My lord, it's hard for me to explain, it's extracted from lard, but it can't treat angina, and there are still two raw materials missing." ”

Lin Hong nodded, wondering if lard could treat angina, he also felt for the first time that the scholar in front of him was not joking with him, at least he had never seen the layered liquid in front of him, it sounded quite doorway and mysterious.

……

……

Early the next morning, Wang Han woke up early.

Once the glycerin is made, it's time for the main event......

"There should have been sulfuric acid in this era of the Ming Dynasty, and it is easier for sulfuric acid to become concentrated sulfuric acid, and nitric acid is ......."

Wang Han frowned again, painted on the ground for a while, his eyes lit up, and then called the housekeeper over and ordered something.

After about half an hour, the butler came back, holding a sorghum stalk and a small half bucket of fire and nitrate, which were placed on the ground.

First, the ashes were burned to obtain plant ash, and after repeated heating, stirring and evaporation, Wang Han finally obtained some long crystals, but the amount was a little small, and it seemed that it was not enough.

"Do you understand the steps?"

Wang Han looked at a small servant left behind to assist him next to him.

The little guy was startled, then nodded.

"What's your name?"

"The little one's name is Ah Fu."

"Ah Fu, you go and call a few helpers, just follow my previous method and get more of this kind of thing." shook the long crystal in the bowl, "If you don't know, ask me, don't pretend you don't know, did you hear that?" ”

"The little one knows."

Wang Han exhaled, with a burning smell all over his body.

Moreover, all kinds of gases are also harmful in the process of nitroglycerin, so Wang Han is not ready to do it himself, and with Lin Hong's resource, he must make proper use of it.

Besides, this day and age...... I don't think there's soap yet, right?

I asked and learned that the things used now are still soaphorns, and the ingredients are nothing more than adding some fragrant things, and the decontamination ability is average, which is much worse than soap, and it seems that after this matter is over, he should also start to develop and develop domestic demand, it is too troublesome to study this kind of thing, and there is no copyright protection in this era, so I can use it myself first......

I have to say that Ah Fu's skills are quite good, except for letting Wang Han point out a few places in the process, it didn't take long for almost a certain amount of potassium nitrate to be manufactured, after collecting, Wang Han gave a word, lay on the stone table, squinted, and slowly fell asleep.

Before dark, Wang Han woke up and looked at Ah Fu and the others who were still busy, and when there was a half jar of long crystals next to him, the corners of his mouth smiled slightly.

Very good, now that he has obtained a sufficient amount of potassium nitrate, after praising Ah Fu, in Ah Fu's flattered expression, Wang Han returned directly to the small courtyard house.

……

……

The next day, Wang Han called Lin Hong again and handed Lin Hong a lot of potassium nitrate that he got yesterday.

"What is this?"

Lin Hong's face was full of doubts, and the little fat man was watching unconsciously beside him, with many stars flashing in his eyes.

"Potassium nitrate."

Lin Hong: "......"

The prefect was obviously very knowledgeable today, because he didn't continue to ask what potassium nitrate was, but looked at Wang Han and knew that he had something to say.

"This is something made of sorghum ash, and it is also a very important raw material, but the tools are limited, and the next steps may be difficult to solve by one person, and I still need the help of Lord Lin."

Wang Han sighed, and then explained to Lin Hong the steps of preparation, and emphasized some special points such as sealing with ceramics after being made.

Of course, in the process, he also said something such as asking Lin Hong to keep it secret, saying that this was the family's generation of single-handed medicine prescription Yunyun, anyway, it was very mysterious, and he almost burst into tears, and Wang Han himself almost believed it.

When he heard it three or four times, he left the Lin Mansion with potassium nitrate unconsciously, and was still muttering to himself before leaving, as if he didn't understand how the ash from the sorghum stalk became this kind of thing? Could this kid be a fool?

After Lin Hong took his things and left, Wang Han finally became idle, said hello to the housekeeper casually, and walked out of the Lin Mansion.

***********************************************************************

In the past few days, there has been a news circulating in Anyang County.

That is, Liu Xi, the chief secretary of Anyang County, came back after being taken away by Jinyiwei, and the person behind him was the prefect, and even more, he said that there were people in the Liuxi Dynasty, otherwise Jinyiwei, who had always done all kinds of evil, would have obediently put people back?

After hearing the news, the county magistrate of Anyang County, the county Cheng and others went to the Liu family with all kinds of condolences, but they were all politely rejected from the door, and then, the county magistrate of Anyang County came to the news of Liu's resignation and resignation, and the county magistrate and others had no result outside the Liu family, and finally returned to the county yazhong, and they did not remember how arrogant they were when the Liu family begged them before, and their faces were as thick as the city wall.

Today's Liu family ushered in an uninvited guest......

The uninvited guest was Wang Han, Wang Han finally took some time out today, facing that woman, he didn't know what his feelings were, in short, he just wanted to help, and felt that woman was a little pitiful...... Human nature, of course, the point is that there is a beauty in ancient costumes, everyone loves beauty, it is normal feelings, not to mention that they have experienced such thrilling things together.

Standing in front of the somewhat dilapidated door, Wang Han sighed.

From the front of the door, you can know how the Liu family is doing on weekdays, this family, if it weren't for the villagers at the entrance of the village in advance to guide the way, Wang Han would definitely not believe that this is a dignified family with a nine-grade master book, to tell the truth, the Liu family is not even as good as the village chief of Wang Village, which official would be in this position?

In later generations, a small village chief can afford to drive a BMW, let alone a high-grade master book, if he remembers correctly, the Jiupin master book will be a secretary and director in later generations, and Liu Xi is mixed with this kind of share, which is enough to prove his integrity.

After shaking his head, Wang Han knocked on the door.

Soon, a familiar face appeared in front of Wang Han, vigilant.

"Is that you?"

Liu Ruyan was stunned for a moment, and on her face, she could clearly see that there were a few tears that had not yet dried up.

"I'm coming to see you." Wang Han smiled slightly, "Is it inconvenient for me to go in and have a look?" ”

Liu Ruyan hesitated for a moment, but still nodded.

……

……

Outside the village, by a small river, the breeze gently caresses the face.

The two sat on a wooden pier by the river and were silent for a long time.

Wang Han is in a more comfortable mood today, he finally escaped death, he can be accompanied by a beautiful woman, this kind of artistic conception has a unique flavor, if this beauty has a gentle temper and speaks softly, that atmosphere will be better, but it is a pity that there is no perfect person in the world, just like Wang Han would never have thought that this is a master anyway.

Just now he has read the book of Lord Liu, the situation is very bad, it is not an exaggeration to describe it with a trace of anger, looking at the tragic situation of Liu Xi up close, Wang Han couldn't help but shudder, he has a lot of fear of the way Jin Yiwei tortures people, and also expresses deep admiration for Liu Xi's temperament, if he changes to Liu Xi, I am afraid that he will be tortured before he has time to use all the tricks, whether it is his crime or not, the torture can be less or less, and the temperament of this thing must also be enjoyed with life......

It's just that what Wang Han didn't expect was that there were only Liu Ruyan's father and daughter in the Liu family, and when she asked, she realized that this was the case when she was a child.

"How's your dad?"

Wang Han looked at Liu Ruyan, who was preoccupied, and took the lead in breaking the silence.

Liu Ruyan shook her head and looked depressed.

"I think surviving safely is the best gift God can give you, isn't it?" Wang Han smiled, where he didn't see it, the corners of Liu Ruyan's mouth twitched, his expression was quite miserable, and the fist that was also behind his back was clenched tightly, revealing a distressing white on his knuckles......

"Wang Gongzi, the grace of saving my life, the little woman can't repay it."

Looking at Wang Han's sincere expression, Liu Ruyan bit her lip, got up and knelt down for him, but was supported by Wang Han, who was quick-eyed.

Touching each other through the thin shirt, Liu Ruyan was startled and hurriedly withdrew her arm.

After a helpless dry cough, Wang Han smiled and said, "You really don't have to kneel, besides, we are friends in life and death, right?" Oh, you don't have a straight face, just laugh a ......"

Before Wang Han could finish his words to adjust the atmosphere, an old doctor came to the entrance of the village, who else was not the doctor who took care of Liuxi in the Liu family before?

"Miss Liu, your father is dying!"

Liu Ruyan trembled......
