The Three Kingdoms began with self-reliance as king

Chapter 260 New Bathing Artifact (Thanks to the monthly pass of "Phantom Addiction Heart")
Liu Yi smiled and reminded: "I can't eat hot tofu in a hurry!
The beggar chicken is wrapped in mud and absorbs a lot of heat. The temperature is very high just out of the oven, so don't burn your mouth! "

With the lessons learned from Guan Hai, everyone would brag about it before eating, and then eat in small bites.

Beggar chicken has a different flavor than barbecue, fat but not greasy, creamy and delicious.

Soon the rest of the beggar chickens were dug out and smashed into mud, and distributed to everyone.

Everyone ate full of praise and was full of interest.

Looking at this happy scene.

Liu Yi thought about waiting for the weather to get colder, and it would be possible to organize everyone to have a hot pot and try some different delicacies.

……

It is worth mentioning that on the way back.

Liu Yi planned to pick some wild flowers to give to Zhang Ning, but found a few fragrant plants.

In later generations, people's various daily necessities are extracted from various plants.

In addition to the vegetable oils that can be used, some vegetable oils and plant essences can also be used to make cosmetics and skin care products.

Of course, with Liu Yi's level and current technological means, it is obviously unrealistic for him to make cosmetics and skin care products.

He can't do nothing.

He still knew how to make soap.

In this era, people use something called pancreas to bathe.

The secret recipe of pancreas is mastered by officials and some gentry.

Luxuries that only a few people can use, it is difficult for ordinary people to have enough food and clothing, so naturally they cannot afford to consume them.

Even if they can afford it, there are not many circulating in the market, and they are bought at high prices as soon as they appear.

Liu Yi didn't expect that this strange item would be a luxury item in this era.

It can be seen that the living standards of the people in the late Han Dynasty were really hard to describe.

As a time traveler, Liu Yi felt that he had to do something for the people of this era.

There was no time to study and make soap before, but now it must be put on the agenda and developed as soon as possible.

Whether it's for Zhang Ning, for the people of the world, or for himself.

……

Liu Yi is a person who thinks and does it.

He locked himself in the hut.

Since Liu Yi made soap with his own hands under the guidance of his teacher when he was a student, he still remembers the general process of making soap in his mind.

So he decided to make soap directly.

There are not many materials needed to make soap, and the procedure is not complicated.

With water, vegetable oil, sodium hydroxide, and a few essentials, you can make easy handmade soap.

Sodium hydroxide is also commonly known as caustic soda.

In the chemical laboratory of the student days, it was not uncommon to see it.

It is not difficult to make sodium hydroxide. It can be made by adding water such as quicklime, sodium bicarbonate, etc., and the supernatant can be obtained after standing still.

After burying his head in the hut and studying hard.

Liu Yi finally succeeded in making the first piece of soap in the late Eastern Han Dynasty.

He was so excited it was hard to add.

Although this is just a small invention, it can benefit countless people.

Just like a small drying rack, although it looks insignificant, it is indeed very convenient for every household.

He can't do much for the people of this era, but it's like "a lowly position dare not forget to worry about the country".

He also hopes to benefit more people through his own heart.

Liu Yi was delighted that he could finally end the hard days of relying on soap or hand rubs for bathing.

A new bath artifact is about to be born!

However, achieving this goal is extremely difficult.

The brunt of the problem is low productivity.

This is a flaw, and the output can only be increased by increasing the input of manpower.

Secondly, it violated the interests of the family.

This problem can be big or small.

It is said to be big because cutting off one's fortune is like killing one's parents. The aristocratic family is definitely not reconciled to this big cake being taken away by Liu Yi.

It is said to be small because people with bare feet are not afraid of wearing shoes. Liu Yi was originally a rebel who started with elite soldiers and mighty generals, and even Huangfusong was captured alive by him.

If the aristocratic families have opinions, they must first weigh their own points and see if it is worthwhile to fight him hard.

The last question is that there was no such thing as a patent in ancient times.

The materials needed to make soap and the making process were studied by the ancients, or they sent people to steal the secret recipe, and they would take it as their own in a short time.

But Liu Yi is not worried about this. If the secret recipe is really leaked, the big deal will be a few more competitors.

It is the common people who benefit from each other's lower prices, so that the rich will not hoard goods, but the poor will not be able to buy them.

Various thoughts flashed through Liu Yi's mind one by one.

He took into account all kinds of resistance and difficulties, but this is a project that benefits the people. Going to benefit the people's life and death, the whole world.

Liu Yi is planning how to expand production, and at the same time is calculating the production cost and pre-sale price.

Only when the final price is within the acceptable range of the common people can he achieve his goal.

Otherwise, you can only take the second route.

Do fine work, monopoly dignitaries.

Make soap into profiteering products like special salt and top-quality shochu.

The specific situation depends on how it is produced.

With a general idea in mind, Liu Yi quickly called the relevant personnel.

Even Zhang Ling, who was far away in Luoyang, was recalled by him.

Not for anything else, but because Zhang Ling is reliable in his work!
Under the leadership of Liu Yi.

The soap workshop was quickly set up, the relevant raw materials were quickly collected, and everything was ready.

The pool in the workshop is filled with clean water, and the raw materials are placed in different categories.

The production staff is checked by Zhang Ling.

In addition, other people are not allowed to approach.

The most important thing in the production process is the extraction and preservation of sodium hydroxide solution.

Sodium hydroxide is highly corrosive and has certain dangers during the extraction process.

If it gets on the skin accidentally, it must be washed with plenty of water, and then apply the corresponding ointment.

Since sodium hydroxide easily absorbs moisture in the air and gradually deliquesces, it should be sealed and kept dry.

Liu Yi must be there to guide these things hand in hand.

Under the guidance of Liu Yi.

Workers throw quicklime into the water.

The huge clear water pool gradually became turbid, and the water temperature gradually increased.

Dian Wei and the others looked at the solemn Liu Yi, wondering what Liu Yi was going to do this time.

Liu Yi was too mysterious in their hearts, and they couldn't figure out his thoughts at all.

Except for Guan Hai, other personnel who have seen Liu Yi refine special salt and make shochu.

They all look forward to Liu Yi's ability to turn decay into magic again.

Liu Yi didn't know what everyone was thinking.

The rise in warm water is due to the chemical reaction between quicklime and water to form calcium hydroxide, which produces an exothermic phenomenon.

Liu Yi did not explain this to them. What he needed was to teach the workers how to make sodium hydroxide solution.

With the addition of an appropriate amount of plant oxalin, the heat release in the pool water became more intense, and the temperature of the entire workshop also increased a lot.

When Dian Wei and the others saw the pool boiling without firewood, their eyes stared straight and their mouths opened wide.

Looking at this scene in disbelief.

My lord really has something!

The surprised expressions of Dian Wei and others couldn't escape Liu Yi's eyes.

He deeply realized that knowledge can really change the world and technology can really create the future.

It seems that when the conditions are met in the future, we must carry out preliminary science popularization for them, lead them closer to science, and understand a brand new world.
