Why do we say that ordinary heroic spirits are arbitrary for eternity?

Chapter 31 Soap, oil wax, caustic soda, glycerin!

Lu Yu didn't intend to do anything illegal right away.

For example, selling private salt.

This business is too risky.

He has many choices, so there is no need to rush.

You can start by doing some business that is not illegal.

For example, Lu Yu used a pot of lard to extract soap, oil wax, caustic soda, and glycerin.

Then soaps and candles were made from soap and oil wax.

Soap and candles were luxuries during this period that most people could not afford.

But as long as it is manufactured, there is no need to worry about sales.

Because in the late Han Dynasty, there were too many powerful landlords.

Wealth has been transferred upwards and is in the hands of a small number of people.

The soap made by Lu Yu is far easier to use than the current soap locust.

Before soap was invented, nobles usually used rice water, soap locust and other items to clean their bodies.

As for the people at the bottom, they use plant ash to clean their bodies.

The emergence of soap is a dimensionality reduction blow!

What's more, Lu Yu also added some spices to the soap to make it a less pungent soap.

Compared with current candles, Lu Yu's candles don't have such a strong smell and don't have too much smoke. They are also of the highest quality.

Once these two gadgets appear, they will definitely become the treasures that powerful people from aristocratic families compete for.

As for caustic soda and glycerin, Lu Yu had no intention of selling these two items.

The former is an important industrial raw material, and the latter is a good thing.

Although the output is a bit low, a little adds up to a lot.

When there is concentrated sulfuric acid and concentrated nitric acid, mix them, then add glycerin, and stir thoroughly to fully react.

This will give you nitroglycerin.

However, the nitroglycerin at this time was not pure and was still a semi-finished product.

The reaction mixture must be filtered to remove unreacted impurities.

Then carry out purification and refining processing.

In order to obtain high purity nitroglycerin.

This thing is much more powerful than black powder!
  As long as the purity is sufficient, the power is 30 times more powerful than traditional black powder, and the explosion speed can reach 5700 meters per second.

The so-called explosion speed refers to the diffusion speed of the shock wave during the explosion. The faster the speed, the greater the impact force.

but.

Nitroglycerin itself is very flammable and explosive, and may detonate with the slightest impact or static electricity. Therefore, special storage and use conditions are required, otherwise it is easy to cause accidents.

For example, diatom mud must be added for neutralization to make a safe solid explosive.

Otherwise, there will be an explosion accidentally, and the consequences will be unimaginable.

Lu Yu's current cultivation level is low. He doesn't want to be the first practitioner to be killed by playing with explosives, so he doesn't plan to study how to make nitroglycerin immediately.

Moreover, the current industrial level is too low. In this era, it is not a simple matter to produce high-purity nitroglycerin.

Making money first is the most important thing.

Lu Yu brought the finished soaps and finished candles to Tang Shigui as gifts.

Since the last time he fought for Lu Yu's interests, Tang Shigui had had a very unhappy time with those powerful men. Coupled with the heavy rain that lasted for a month, his business had been seriously affected. It could be said that he suffered heavy losses and his life was not good.

However, Tang Shigui was very happy when he heard Lu Yu coming and immediately went out to greet him.

"Brother Lu, I haven't seen you for a long time. The rain a few days ago almost made me moldy all over, and I didn't even have the chance to walk around." Tang Shigui said with a smile: "Today we must have a good talk, and it's best to hold the candle at night. talk!"

"I brought some gifts to Brother Tang. I'm sure Brother Tang will like them." Lu Yu smiled and lifted the box in his hand.

"Brother, it's fine if you can come over. Why don't you bring any gifts? You're really unreasonable!"

Tang Shigui didn't think much about it at this moment, and he didn't know what kind of gift Lu Yu had brought to him. He welcomed Lu Yu into the house all the way.

After a simple greeting.

Lu Yu took out his gift and said straight to the point: "I came here this time because I have something to discuss with Brother Tang."

Tang Shigui looked at the two objects in front of him and asked curiously: "This is a candle, what is this?"

"This thing is called soap." Lu Yu replied.

"Soap?" Tang Shigui frowned. He could vaguely understand the purpose of this thing from the literal meaning. He guessed: "Is it made from soap locust? Does it have a cleaning effect?"

"Yes, this thing is used for cleaning, but it is not refined from soap locust, but it is much easier to use than soap locust. Brother Tang will know after trying it." Lu Yu nodded.

The two came outside the house, and Tang Shigui called a subordinate who was training.

Because it rained for a month, the training ground was full of mud and water, but even so, we still had to practice. The clothes were already extremely dirty, and occasionally there was some oil stains on them that couldn't be washed away. Over time, this became The clothes are quite miserable.

"Take off your clothes and wash them with these things." Tang Shigui ordered directly.

Without hesitation, the men took off their clothes and washed them in the pond next to them.

The effectiveness of soap in removing stains is amazing.

It was just a simple scrubbing, which produced a lot of foam. After soaking again, it suddenly became much cleaner.

Seeing such an effect, Tang Shigui's eyes lit up and he decided to try it himself.

He had just studied the candle sent by Lu Yu, and his hands were stained with a lot of oil, so he happened to use this thing to wash his hands.

I simply washed my hands with soap, and the oil stains were immediately removed, leaving no trace behind.

“This thing is so convenient!”

Tang Shigui couldn't help but admired it. He instantly realized the power and value of this thing.

Tang Shigui then pulled Lu Yu into the room and quickly asked about the cost of making the soap.

The cost determines how much profit the item can make.

"This product is made from lard." Lu Yu said, "About twenty pounds of lard can make twenty pieces of soap and a dozen candles."

One kilogram in the Eastern Han Dynasty is equivalent to 224 grams today, so it is said to be twenty kilograms, but in fact it is less than ten kilograms.

"Do you just need this lard?" Tang Shigui's eyes lit up and he asked again.

"Of course not, you still need some auxiliary materials, but they are not expensive. The most expensive thing is the spices. This is very important. It can turn the lard soap into the current soap and make the unpleasant smell disappear." Lu Yu explained.

"This……"

Tang Shigui looked at the two items in front of him in disbelief. He thought that the refining price might be very low, but he didn't expect it to be so low. He only needed lard to refine it.

Although lard is a treasure in this era, to the powerful Tang Shigui, lard is not a valuable thing at all. This soap is a treasure.

The most important thing is that this thing is still a consumable! !
  A valuable consumable!

The commercial value of this thing is simply unimaginable.

Tang Shigui's breathing became slightly heavier.

Lu Yu really gave me a big gift!
  "My brother gave this to me because he plans to cooperate with me in selling it?" Tang Shigui glanced at Lu Yu and asked.

It's easy to talk to smart people. Lu Yu nodded: "If not, why would I come here?"

"Brother Lu, how are you going to cooperate?" Tang Shigui asked.

"I'll pay half a million, and then I'll give you this refining technology, and I'll get a [-]% profit. Brother Tang, how much do you want to pay?" Lu Yu said slowly, then asked the question to Tang Shigui.

When Tang Shigui heard this, he couldn't help but frown and think. After a while, he raised his head and said seriously: "My family can contribute four million, plus all the trade routes our family has, we will also get [-]% of the profit. How about it?"

"Not enough." Lu Yu shook his head.

"Five million!" Tang Shigui knew the profit and immediately raised the price.

"Okay, but I have one condition." Lu Yu said.

"Please tell me!" Tang Shigui said quickly.

"In the process of refining lard, in addition to producing oil candles and soap, it will also produce two substances, which I named caustic soda and glycerol." Lu Yu thought for a while and said, "But I can't study these two substances for the time being. What are the uses of things, so they all belong to me and I can continue to study them, how about it?”

"Of course!" Tang Shigui nodded without thinking. If he researches something useful, he can continue to cooperate!
  After preliminary negotiations on cooperation, both parties were very satisfied with the result.

Tang Shigui knew that Lu Yu's methods were unusual, so he had no intention of fooling Lu Yu, and he didn't dare to kick him out. It was better to cooperate honestly and win-win!
