Chapter 397: vulgar! How vulgar!

Chapter 397 Common! How vulgar!

“As expected, it still doesn’t work!”

Looking at the soft stuff in the bowl, Feng Yong poked it with his hand and finally grunted.

Although it stands to reason that the finished product must be dried in the shade before it can take shape, but looking at its current appearance, Feng Yong no longer has any hope for it.

Although I was extremely bored and thought about trying to use tung oil to do this, I still had hope in my heart. Now that hope was shattered, Feng Yong was extremely disappointed.

 Putting the contents of the bowl aside, he lowered his head and looked at the waste liquid carefully. Finally, he sighed and cursed: "Damn it, if I had known, I would have studied chemical industry!"

“Brother, what is the use of this thing?”

Zhao Guang’s whole body was shaking slightly uncontrollably, especially his hands, which were shaking so much that he looked like a patient with Parkinson’s syndrome.

What a pity that when he looked at what he had worked on for a whole day, he could not understand anything.

Feng Yong glanced at this brave guy and said calmly, "It's useless. It's a failure."

“What…it’s of no use?”

Zhao Guang's pupils suddenly widened, and he looked excited: "How can it be of no use? How is it possible? I've... been busy all day and it's of no use!?"

“I just did it when I was bored.”

Feng Yong saw that this guy had the urge to run away, and immediately comforted him, "It's also of some use. After it dries, you can try using it to wash clothes!"

“Can it only be used for washing clothes?”

“This is useful.”

Feng Yong quickly pointed at the waste liquid and said.

"What is the use?"

 Zhao Guang had doubts in his eyes. It seemed that Feng Yong's credit was temporarily overdrawn by him.

“Apply it to your hands, feet and face in winter to prevent freezing.”

The by-product of making soap is glycerin, which is a good thing.

Those skin care products of later generations will all contain this kind of thing.

Because it can moisturize the skin, and most importantly, it can prevent the skin from freezing and cracking.

Especially in this Little Ice Age era, when the north is getting colder and colder, the role of glycerol will become more and more prominent.

For the soldiers of the Northern Expedition a few years later, this was an extremely good thing.

However, the Northern Expedition cannot be talked about at the moment, so Feng Yong can only vaguely say that it can prevent freezing.

Furthermore, this soap-making experiment is already considered a semi-failure. Feng Yong doesn’t have much hope that glycerin can be filtered out of the waste liquid.

But who calls Zhao Guang chemically illiterate?

I say yes, but if you don’t accept it, use your chemistry knowledge to argue with me!

Zhao Guang, of course, has never studied chemistry, but he has eyes.

Looking at this liquid whose color is unclear, if he really believes that applying it on his face can prevent him from freezing, that would be a real test of his IQ.

The suspicion in his eyes deepened.

“Of course it cannot be applied directly, it must be filtered out again.”

Feng Yong believes that Zhao Guang’s IQ is not that low. “You need to put some filtered lime water in it to make it.”

Mix plant ash water and lime water together to obtain potassium hydroxide.

Use this to precipitate glycerin through saponification reaction.

Although Feng Yong does not have lime at the moment, he does have a lime mine in Hanzhong, and it is a first-grade large-scale mine with hundreds of millions of tons. Even if he cannot produce ideal soap by then, he will still make money if he can produce glycerin. .

So Feng Yong continued to fool Zhao Guangdao, "I will show it to you when I get back to Hanzhong."

If you really make glycerin, in addition to selling it to Zhuge Lao Yao for the Northern Expedition, you can also think of ways to add some floral fragrance to it, and make some cosmetics and skin care products to bring delicate skin to the women of the Han Dynasty, that would also be great.

Let’s make a slogan at that time: If you want good skin, use Dabao sooner or later. See you Dabao tomorrow, see Dabao every day...

Isn’t it a pleasure?

“Come here, bring up that armor.”

Feng Yong temporarily fooled Zhao Guang, and then gave orders to his servants.

A pair of shiny armor was quickly brought over.

“How is it? Is it effective?”

Looking at the armor in Lao Pou Lu's hand, Feng Yong asked.

Lu Laozu said with joy on his face, "It's useful when I go back to my master's house. A few days ago, I applied tung oil on it as Lang Jun said, and then specially poured water on it. After leaving it for a few days, I didn't find anything." There are signs of rust. It’s very different from before.”

"In the past, the armor made of iron, not only if it was stained with water, but also if it was left unused for a long time, had to be taken out and wiped from time to time to prevent it from rusting. Not to mention that if it was accidentally stained with water, it must be carefully cleaned Just wipe it dry."

"Otherwise, if it gets rusty, it will deteriorate quickly. Now that I've applied this tung oil on it, it doesn't rust easily. Even if it's stained with water, I haven't seen any rust after leaving it for a few days. It's really a good thing."

Of course it is a good thing. Even in the World War II era when industry had developed rapidly, tung oil was still a must-have for maintaining weapons.

It was regarded as a rare strategic reserve material for China at that time.

Even in the 1950s, China still controlled 90% of the world's tung oil exports. No matter how disgusting Meirenxi was, she had to hold her nose and pay high prices to buy tung oil in Hong Kong.

“See? This is very useful.”

Feng Yong activated his special skill "Spoken Words" and said to Zhao Guang, "What you just did was just a trivial matter. The main purpose of this tung oil is to maintain this armor and weapons."

"Look at this weapon and armor. It doesn't need to be said that it will never rust. As long as it can be easily prevented from rusting, then the benefit will be great. This is a big deal."

Nowadays, most of the armor used by soldiers is leather armor. Those who can use iron armor are at least like generals.

The little soldier below is lucky to have a pair of tattered leather armor.

Iron armor has high protection. With it, your chances of surviving on the battlefield are much higher than others.

But iron is scarce, and iron armor is even rarer.

And its maintenance is also a big problem.

In this era, the quality of iron was generally not high. Not to mention iron armor, even the weapons in the hands of soldiers were broken when they were chopped and chopped on the battlefield.

Once rusted, it is more susceptible to damage.

With the large amount of tung oil produced, it is much easier to maintain weapons, let alone iron armor.

Zhao Guang may often make mistakes in other places, but when it comes to marching and fighting, it is like a different person.

The reaction came to his mind immediately, "No wonder my brother asked someone to send this tung oil over. Is it for this purpose?"

As he spoke, he immediately snatched the armor from Old Soldier Lu's hand and looked at it carefully for a while. Then he raised his head with a look of surprise on his face, "It turns out that my brother went to the mountain a few days ago not to relax, but to relax. Are you looking for the poppy tung tree that produces tung oil?"

“That’s right.”

As he spoke, Feng Yong took out another bill from his arms, flicked it, and it made a clear "click" sound, and asked, "What is this?"

“ticket.”

“Do you know the difference between the ink on this note and the ink commonly used by others?”

“Naturally I know that there is oil in this ink.”

"Yes, there is oil in this ink. In the future, Nanxiang will not only print banknotes, but also print more books, so more and more ink will be used. Looking at the Han Dynasty, where has the most oil?"

In order to break the family's knowledge monopoly, Feng Yong not only used a large amount of paper, but also used a large amount of ink for printing.

Since you need to use so much oil, you can’t just use lard again, right?

In terms of the amount of oil, which one has the most oil?

The output of tung oil is the largest in Nanzhong.

As long as the people of Nanzhong can make a fortune, who will be willing to rebel?

As long as no one is willing to rebel, isn't the political mission assigned by the old demon Zhuge completed?

Do you care whether I made money during this period or whether I poached a corner of the family?

Obviously, the notes exuding the scent of ink attracted Zhao Guang's attention more. His eyes lit up, "This tung oil has so many benefits, and this tung oil is everywhere in Nanzhong, so don't we have it again?" Are you going to make money?"

“Vulgar! Really vulgar!”

Feng Yong glanced at Zhao Guang and criticized his ungraceful words, "We came to Nanzhong for the peace of the people of Nanzhong, not to make money for ourselves!"

"Look at how Nanzhong has been ruined by the rebels. The people can't even get peace, let alone food and clothing. So we asked the people to go to the mountains to collect some tung seeds in exchange for food. Then It’s for their own good, do you understand?”

"The people are pitiful," Feng Yong sighed, very pitiful. "Even after Nanzhong was pacified, it doesn't mean that crops will grow immediately in the fields. Useless tung seeds are exchanged for food to tide over the difficulties. , who dares to say that this is not saving lives?”

"Yes, yes, yes!" Zhao Guang nodded repeatedly, "Yes, that's it. The elder brother is still kind-hearted, but the younger brother realizes his mistake."

Then he came over and asked in a low voice, "Brother, can we ask the people in Jincheng to prepare food?"

"Why are you so anxious?" Feng Yong said angrily, "Although the price of food has not risen as much as the year before, it has risen after all. Wouldn't it be a big loss to buy food now?"

"Tung trees can only be picked in autumn, which happens to be the time for harvesting grain in Jincheng. I estimate that by then, the prime minister will have almost put down the rebellion. Once the news comes back to Jincheng, the price of grain will definitely drop to the lowest. , this is the only cost-effective way to buy food.”

“The people in Nanzhong didn’t plant much food this year, so it’s good for Jincheng to transport food for them to survive the winter, and at the same time to calm people’s hearts.”

“Sure with one stone! My elder brother is still the best.”

Feng Yong’s careful calculation made Zhao Guang raise his thumbs up in sincerity.

Wang Xun’s face was expressionless, and his outlook had long been numb.

But when Yang Wanwan heard this, his heart felt like ten thousand mythical beasts running through him: Is this the young hero Feng Langjun who was praised by the prime minister?

The most handsome young man in the Han Dynasty, who was praised by the Empress of the Han Dynasty, looks like this?

Sure enough...it makes sense!

If his father had such a plan back then, would he still be driven out and homeless? It's hard to say that he can even swallow up his enemies and strengthen his own tribe.

The Han people are indeed too cunning, but we Hu people are still upright.

Yang Wanwan had a lot of thoughts in his mind, and then secretly made up his mind that I must learn from my brother!

Feng Tibi had no idea that he, the source of pollution, had polluted another young man with great ambitions.

"Pour this out." Feng Yong pointed at the waste liquid and then at the soap, "Put this in a dark spot and wait until it dries to see what it looks like."

"I come!"

As soon as Yang Wanwan heard this, he said quickly.

He did not let his servants do it, he did it himself.

Feng Yong washed his hands, walked into the house, took out a wooden box, took out a notebook and a charcoal pen, turned to a page with the "Tung Oil" catalog, and then began to record:

The failure to make soap proves that tung oil is not a good raw material for making soap.

Maintaining weapons and armor is currently possible.

The production of glycerin is unknown.

He thought for a while, and then added two more sentences: Potassium hydroxide has relatively active properties, so you can try to use potassium hydroxide to make glycerin. Potassium hydroxide can be made from potassium carbonate and calcium hydroxide.

After writing, put the last two sentences in parentheses to indicate supplementary content.

Finally he put the notebook away again and put it carefully into the box.

This box, no matter where he goes, must be taken with him. It is full of past life knowledge that he has inadvertently remembered in his daily life. Regardless of whether it is useful or not, as long as he can remember a little bit, he will write it down.

There is another box like this in Fengzhuang, Jincheng.

The only difference from the one next to him is that Feng Zhuang's box is already filled with things he has written.

The reason why Feng Yong takes the trouble to write down everything he can remember is because he is afraid that after being in this era for too long, he will gradually forget everything from the past.

I patted the box and sighed. The loneliness deep in my heart has never disappeared, because the things in the box have always reminded me that I am different from others.

While Feng Yong was writing, Zhao Guang and the other three consciously stood guard at the door so that no one would disturb him.

The box is full of knowledge from the sect, this is what the elder brother told them.

Moreover, my brother has never shied away from writing this thing in front of them. They can even read it if they want - it's a pity that none of them can understand it.

Most of the knowledge, even though they can understand the words, they cannot understand the meaning between the lines.

It is said that the Book of Heaven has no words. I think that although my brother’s knowledge is not up to this level, but there are words but people can’t understand it, that’s very impressive.

Of course, there are a small number of them who can understand it.

Seeing that Feng Yong had finally finished writing, Zhao Guang walked in, took a quick look, and then said, "Brother, have you finished writing?"

“Well, it’s finished.”

“So fast?”

Zhao Guang's face lit up after hearing this. He hurriedly went over to rummage through the box, and then took out a notebook. On the cover of the notebook, he saw four big words written on it: "Fight to Break the Sphere".

After a while, Zhao Guang said disappointedly, "Brother, why hasn't it been updated yet?"

Feng Yong glanced at the guy who was urging him to wake up, and said slowly, "What's the rush? You have to let me think about it slowly."

“Well, brother, can you tell me first whether the little medical fairy helped Xiao Yan heal his injuries?”

Zhao Guang sat next to Feng Yong and asked flatteringly.

"what is the benefit?"
