Zhao Huaizhong walked nearby and picked up the fragrant and green-colored block.
This is an ancient soap.
The principle of making soap is simple, so it has a high rate of appearance in novels.
Mix animal and vegetable oils with natural alkali to form saponification.
Then heat and cook, stirring continuously, for several or even ten hours, until the materials are further saponified, and then add salt to promote the agglomeration of the soap base.
Then put the rested material in the mold and fix it, which is the original soap.
Natural substitutes can be found for all materials, and there is no deep processing process.
This thing may still be difficult for ordinary families to make now, but for Zhao Huaizhong, it is just a matter of a few words. Lao Sikong and his craftsmen tried repeatedly to find the best salt-alkali ratio, and finally made the current product.
The best soap ever.
Because it contains salt-alkali reaction, it can sterilize, cleanse and remove greasiness.
Zhao Huaizhong took the soap in his hand and let out a long sigh.
No one can understand how troubled a time-traveler like him who is a little mystic feels when he comes to a world without toiletries.
it's good now.
Lao Sikong also mixed precious herbal juice into the soap, making it emerald-like in color and fragrant in smell.
Zhao Huai gave it a try and washed his hands with soap for the first time in this world. He was very happy.
Old Sikong observed the words and said with admiration: "I wonder how the prince came up with such an ingenious thing?"
"I was a hostage in the State of Zhao, and I came up with many ideas when I had nothing to do. After trying, some of them can be realized, and some of them can't." Zhao Huaizhong joked casually.
Everyone immediately followed Lao Sikong into the second room.
This room is researching the use of silk pulping methods to make paper and the technology of movable type printing.
Lao Sikong's expression also cheered up, and he said: "This thing called paper that the prince mentioned, we have made the finished product after many attempts, but it still cannot reach the uniformity and fineness required by the prince.
If this paper could be made, it would shake the seven kingdoms."
Lao Sikong studied the art of making things carefully and was keenly aware of the epoch-making importance of paper.
His admiration for Zhao Huaizhong mainly came from paper manufacturing.
Because there is no concept of bacteria, soap and other things are just luxury items in Lao Sikong's eyes. What he values more is paper technology.
In the past few days, I have personally supervised the production of paper.
This paper is so rough that it is easy to scratch even if you open your buttocks... Zhao Huaizhong touched the paper that Lao Sikong brought up. It was light yellow, very thick, and the surface texture was rough and uneven.
"You can study the floating wadding method again, and superimpose the waste wadding left on the silk. It should be more tough.
It’s so rough, you may have had a problem while beating it.”
The common sense that everyone knows in modern times is an unprecedented theoretical discovery in this era.
This is the advantage arising from the time traveler having the knowledge of two worlds at the same time.
Zhao Huaizhong said a few words casually, but Lao Sikong heard that he had a high-level view. He was so shocked that he asked for advice frequently.
After Zhao Huaizhong responded one by one, he added: "I asked you to use another special kind of silk to make paper. How is the progress?"
Lao Sikong blushed slightly: "It's about the same progress as ordinary paper. I'm afraid it won't satisfy the prince."
Then someone brought in another kind of silk paper with a light yellow color.
This kind of paper is made of special silk and is extremely tough. It is the raw material Zhao Huaizhong plans to use to make paper puppets.
He pulled it with his hands and tried to attach magic power to the paper.
I found that the toughness was pretty good and the mana adhesion was barely up to expectations, so I motioned to go to the next room to check.
"besides…"
At this time, Fan Qingzhou was also a little shocked.
He glanced at the papers in the room, thoughtfully.
This kind of paper is used to transmit messages. It is easier to carry than bamboo scrolls and is much more concealed. It can obviously be used in the message transmission system of Ye Yu Mansion... This kind of thing must be kept strictly confidential and cannot be spread... Fan Qingzhou quickly reported the appearance of the paper
, rising to the perspective of strategic materials.
In the third room, there is a long table about ten feet long.
Holes were dug out in the four corners and symmetrical positions in the middle of the table, and wide openings were polished on the edges, with cloth bags underneath.
The tabletop is covered with fine fine velvet animal skins.
After Fan Qingzhou came in, he walked around the stage and looked at it for a long time, not knowing what it was.
Zhao Huaizhong was quite satisfied.
Unexpectedly, Lao Sikong really solved the billiards case in just a few days.
This thing needs to be polished smooth, and the fine velvet on the table must take into account the resistance of the ball speed. In modern times, it also needs to be carefully crafted, which is not easy.
Fortunately, if you don't have enough technology, you can use mana to make up for it.
Technical problems are solved by non-technical means.
For the flatness of the table, Lao Sikong hired a practitioner who was proficient in vertical and horizontal techniques to tell him that it should be flat and not undulating. When making the ball, he also said that it should be round, uniform, and uniform in size... The result was a wooden billiard ball that was even.
Place them uniformly on the table.
Of course, vertical and horizontal techniques also have their own rules and restrictions. It is impossible to say what they are, and they need to comply with the rules of physical properties.
Zhao Huaizhong tried to play a few games of billiards, but the resistance of the fine velvet on the table was too great, and the ball speed was too slow, which was obviously wrong.
But many people in this world have practiced cultivation and have great strength, so it is appropriate to use them.
Billiards can be a pastime in one's free time, Zhao Huai thought, so he asked Liu Qi to ask people to transport everything back to the palace.
After checking these things, Zhao Huaizhong walked first.
However, Fan Qingzhou looked solemn and said to Lao Sikong: "These items proposed by the prince to be made are strictly forbidden to be spread to outsiders. You must restrain your subordinates."
Lao Sikong said: "I have been Sikong for so many years, why don't I save these things?
These things are for the prince's use and will not be spread to outsiders."
Fan Qingzhou thought for a while: "What are the values of these things?"
"It's all very high. Just the herbs added to the soap make me reluctant to use it to clean my hands," said Lao Sikong.
Fan Qingzhou said: "It's just right if you don't want to use it.
Liu Qi took away all the soaps that were in good shape, but the remaining ten pieces are unevenly shaped, how about you give me some?"
"No." Lao Sikong rolled his eyes and flatly refused.
…
In the evening, Zhao Huaizhong returned to the palace and took some soap to send to Zhao Ji and King Zhuang Xiang first.
After returning to the palace, His Royal Highness took a soapy bath for the first time since time travel and felt refreshed.
The next day.
After dawn, Zhao Huaizhong watered the gourds for the third time, using up the last drop of liquid in the container.
After attending the court meeting, he came to Xuangu Academy. When the carriage drove into the academy, Wei Yang came out from the palace on one side to greet him and bowed to Zhao Huaizhong.
"Excuse me, sir, I want to meet you at the academy." Zhao Huaizhong said.
"It doesn't matter, I often come to the academy, and Prime Minister Lu has no time, so I will teach him the miscellaneous skills." Wei Yang apologized respectfully.
The two walked forward slowly, talking as they walked, and soon arrived at the school building.
The atmosphere in the school building was noisy, and a group of teenagers led by Wang Ben looked red-faced and somewhat indignant.
When he saw Zhao Huaizhong, Wang Ben rushed over to greet him.
"What's wrong with you?" Zhao Huaizhong asked.
Wang Ben's face showed a gloomy expression as if he had encountered a natural enemy, and he said fiercely: "Today there is a new guy in the academy. He is from Qi State and is now a guest of Prime Minister Lu's Mansion.
This guy relies on his appearance to get close to women, which is annoying."
Another young man added: "The most hateful thing is that that guy just came today and went to find Jiang Shu and talk about how to cultivate vegetation. Looking at Jiang Shu's look, he actually agreed with what he said. We were so angry.
"
Zhao Huaizhong laughed and said, "Who are you talking about?"
"Lao Ai." Wang Ben said in a deep voice.
"...This man died miserably."
In the history, there was a man who wanted to be the fake father of the First Emperor, but ended up committing suicide. He was a famous wealthy man in history?
Zhao Huaizhong always felt that people like Lao Ai were not very smart, so no wonder he was dragged away by the car.
