Spoiling History: Starting from the Three Kingdoms

Recalling his experiences over the past few days, Pang Tong felt the urge to burst into tears.

Later generations said it was easy, but after actually getting started, I realized how difficult it was.

After all, he almost knows the process of making alkali. It may need to be heated, left to stand, or stirred. Every step is very orderly.

But this soap just says it can be made by adding oil.

Lard or sesame oil? Strong alkali or light alkali? Does it need to be boiled and heated? Or just mix and dry?

Pang Tong couldn't answer all kinds of questions, so he could only ask Kong Ming for advice. He used different raw materials and different techniques according to the instructions, and selected the best based on the conditions.

After sifting through all kinds of unreliable and failed methods, what was finally placed in front of Kong Ming were these white stone-like things.

Kong Ming knocked with a small iron rod and listened to the "bang bang" sound, and then naturally raised his doubts:

"What's the use? How to use it?"

"Uh..." Pang Tong suddenly got stuck.

After two days of sleepless nights and food, I finally made this thing. I was so excited that I forgot about it.

Kong Ming was used to this. Based on past experience, he first deduced from the name:

"Fat means abundance and prosperity, and soap has the ability to dye."

"Based on the name, the efficacy of this product may be related to the coloring of Ma Ge."

But if it's just dyeing, it probably won't be worth the trouble.

After all, judging from the younger man's tone, it was enough to make the centuries-old rice paper technique troublesome. The only explanation is that soap is far more valuable and effective than rice paper.

Now that there are speculations, the next step is to try them one by one.

For Kong Ming, he had accumulated a lot of experience in exploring the relationship between soil and crop acidity, so after giving the order, more than a dozen pieces of cloth were quickly delivered here.

Hemp, kudzu, and silk are all available, and they are all available in plain and dyed colors.

Then Kong Ming took out his hard pen, opened the small notebook he carried with him, stood aside, and made an invitation gesture to Pang Tong.

Pang Tong did his duty, but everyone was soon disappointed that the "soap stone" did not seem to have any magical effect on these clothes.

Dry wiping didn't work, and I tried adding water but still no special reaction.

After trying on clothes of various colors and materials, Pang Tong looked at his hands a little unsure:

"It seems... cleaner than before?"

Jian Yong, who was watching quietly from the side, also saw this attempt. He immediately took off his blouse and said with a smile:

"You'll know after you give it a try."

Just now, Xia Houyuan and his lord were entertaining Xia Houyuan for a banquet, and there were many stains on their clothes.

Soon, as the stains on Jian Yong's blouse disappeared like winter snow meeting the sun, Kong Ming also wrote down in his notebook:

"It doesn't have the ability to dye, but it actually has the effect of removing stains, and it seems to be able to be used for bathing?"

Seeing that Pang Tong's hands were white and rosy, Kong Ming vaguely understood why this thing was better than rice paper in the eyes of younger generations.

Rice paper can be used for writing, but hemp paper, bamboo slips and wooden slips can also be used.

Everyone likes to be clean, and there may be few substitutes for the effectiveness of this soap.

Looking over there, Pang Tong was still thinking about the more useful functions of this thing. Then he looked at the nearly one-person-high pile of failed products in the corner of the workshop. The hardships can be seen at a glance.

After taking two steps, Kong Ming became curious again: "What is this?"

Placed in another corner of the workshop were pots of something that looked like oil but not oil. It was thick but had a subtle fragrance that made people feel relaxed and happy.

"This is the glycerin used to make soap, and it has many miraculous effects."

"Glycerin?" Kong Ming repeated the name.

Pang Tong stepped forward and explained: "Because it has a subtle sweet fragrance, I wanted to call it sesame oil, but I was afraid of being confused with sesame oil, so I called it glycerin."

"As for effectiveness..."

Pang Tong picked up a bowl of glycerin with a richer color and led everyone outside the house for nearly two hundred steps.

After Jian Yong protested, he carefully put the bowl away, took out a smoldering fire stick from his body, blew out the open flame, and threw it directly into the bowl from a distance.

With a "boom", a pillar of fire that was nearly a person tall immediately shot up from the bowl, illuminating the surprised expressions of several people.

Pang Tong took two more steps back to ensure that the flames would not affect him before explaining:

"This substance is flammable, much better than tung oil, and it will be of great use."

"After making it, I gave a bottle to Divine Doctor Zhang, who said that this substance might also be used as medicine."

For Kong Ming, what he saw today was full of surprises. Overjoyed, he couldn't help but pat Pang Tong on the shoulder and said:

"This soap and glycerin will be of great use!"

"With this thing alone, Shi Yuan will be famous in history!"

Hearing Kong Ming's approval, Pang Tong suddenly smiled from ear to ear.

Kong Ming couldn't help but feel in a daze, feeling that Chang'an might be reestablishing the Ministry of Work Skills next.

Because there were not many things that needed to be busy researching at the time, the Gongqiao Department of Public Security County became in name only after Liu Bei and Kong Ming both left for Chengdu.

But now Kong Ming felt that it was necessary to establish an engineering department in Taixue. After all, not to mention the distance, the soap would change its efficacy, increase its color and sweet taste, and the supply would exceed demand.

Glycerin is even more troublesome. Since it already has such effects, what if sucrose is added? What if it is made with gunpowder?

As well as what Doctor Zhang said could be used as medicine. All these possibilities require hundreds of people to try and record them.

So finally Kong Ming remembered the words of later generations and sighed:

"Knowledge can change a person's life, improve the destiny of a community, and build the momentum of a country."

"If you want to destroy the Ji Han Dynasty, you should promote the Imperial Academy to all the states and counties in the world."

“To strengthen a country and rejuvenate its people, we should start with education.”

Pang Tong, Jian Yong and others believed this deeply. This truth does not need to be explained by later generations. They themselves are the most obvious examples.

…

It wasn't until August that Bu Zhao finally left the city of Chang'an, which was on the rise.

Looking back on the changes in his mentality before and after this trip, Bu Zhi just wanted to look up to the sky and sigh.

Sun Hou asked him to travel thousands of miles to Chang'an to ask for the withdrawal of troops, and he listed his sincerity, including but not limited to the reconciliation between the two families as before, the selection of men and women of suitable age for marriage, the plan to promote business and fight against Cao Cao, and the willingness to send troops to Hefei. With the momentum of aiding Jingbeiguan Yunchang, etc., every condition has room for negotiation.

For example, if General Zuo is willing to provide some money and food, it is not impossible to ask Jiang Dong to respect the emperor's uncle...

But unfortunately, after several conversations, Bu Zhi also summarized the current situation:

Marquis Sun was full of sincerity, but General Zuo lacked interest.

Although Bu Zhi also knew that after his previous betrayal, there was still a question mark as to Sun Hou's sincerity.

But considering that Mrs. Bu has only been in Sunhou's house for less than a year, and the expectations of the whole family are on his shoulders, Bu Zhi can only bite the bullet and continue talking.

Fortunately, in the end Liu Bei agreed to the request to stop the troops. Bu Zhi guessed that perhaps it was because Lu Zijin elaborated on the pros and cons, or perhaps because Mrs. Sun still remembered the old friendship of Marquis Sun.

After all, the conditions for the strike are not harsh, and can even be said to be generous:

Marquis Sun only had to agree that Jiangdong would be opened to cross the Yangtze River, and he would not be allowed to interfere with trade.

That's it.
