"Master Tong, the rubber has arrived?" Ren Baqian just heard that more than a dozen ox carts filled with wooden barrels arrived at the work department, so he hurried over and happened to see Tong Zhenye and the ox cart filled with wooden barrels in the yard.

"Mr. Ren is here just right." Tong Zhenye smiled and said, "Let's see if you want it? There will be good things for you later."

Ren Baqian rubbed his palms and opened a wooden barrel lid. It was filled with milky white rubber. Unlike the rubber that was dried last time, the rubber juice collected this time was sealed directly in the wooden barrel and then traveled a long distance to Lancheng.

"That's it!" Ren Baqian laughed after smelling the smell. After waiting for so long, he finally arrived.

With these rubbers, a lot of things have begun to work on.

"These rubbers are sent to Zizhu Academy and the others are sent to the Beast Garden." Ren Baqian made arrangements first before asking Tong Zhenye: "Is the soap ready?"

"As you said, make a batch, and you are here to go and have a look with me." Tong Zhenye said with a smile on his face.

It is said that the price of the genus is not low in Izumo, let alone in Dayao. Only a very small number of people can afford it.

But unexpectedly, this kind of thing is so simple to make. As long as you know the production method and find a few people, you can create a useful pancreas.

And as Ren Baqian said, mashed petals were added to it, so that these soaps could create several colors and also had the aroma of petals, which looked much better than the pancreas sold by the Izumo people.

This made Tong Zhenye quite content.

Although this pancreatic sap was made according to Ren Baqian's words, it was also the achievement of the Ministry of Works.

You should know that Da Yao has too few things, and every extra thing he doesn't have will make him excited.

Ren Baqian went out of the city with Tong Zhenye and came to a newly built yard on the outskirts of the city. The yard walls and the houses in the yard were made of red bricks.

Someone saw the two of them coming here with their guards and immediately welcomed them inside.

In a larger warehouse, Ren Baqian saw the newly prepared pancreas, which according to Ren Baqian's words, it was soap.

This pancreas is made by grinding the pancreas of the goat, adding wood ash, animal fat, and mixing it and stirring it into a thick shape. Then add the powder of the flowers and press it into pieces, then put it on a rack for drying the vagina and then dicing it into pieces.

When Ren Baqian came to the warehouse, he saw a large chunk of pancreas placed aside, and there was a sink under the shelf to guide the dripping liquid into the bucket.

This liquid is a by-product of soap production - glycerin, which is more important than the soap itself.

Glycerin can be made into nitroglycerin, as well as diatom manganese earth explosives and colloidal explosives, and even smokeless gunpowder.

Of course, Ren Baqian was not prepared to use this explosive that was extremely prone to explosion in war. There is no secret in the world that can be permanently protected. The birth of explosives and gunpowder poses great threat to the ancient tribe with sparse population but strong individual strength.

If explosives and gunpowder develop, the advantages of the ancient tribe will be greatly reduced, and the disadvantage of sparse population will be extremely obvious.

So Ren Baqian was ready to control this thing firmly in his own hands.

If explosives and gunpowder were not a hurdle that could not be avoided in the development of technology, Ren Baqian would not want to make it.

Ren Baqian walked around the warehouse and picked up a few pieces of cut soap next to him, with three aromas in total. One of them was very popular with the empress. The production was a bit rough, but it was quite good for the beginning.

Ren Baqian first asked someone to make a basin of water, washed his hands with soap to see the effect, and then turned around and asked, "Sir Tong, how do you plan to sell this soap?"

"I don't know..." Tong Zhenye shook his head: "Before Jingyan, the imperial court never had a precedent for selling things. So this thing was made, but how to sell it, His Majesty still has to make the decision."

Ren Baqian nodded slightly and threw the soap to the guard behind him.

"Master Tong, I will let you deal with these glycerols when you look back." Ren Baqiandao. The production of soap will inevitably produce a large amount of glycerol. In addition to a few of these glycerols used as solvents, the rest must be found to be treated in a place.

He is not going to hand over this kind of thing to others.

"Is this thing useful?" Tong Zhenye wanted to ask about this for a long time.

"Some use, but not much better." Ren Baqian waved his hand.

Then the two went to several other warehouses to check out. These were dried and ground pancreas, ground flowers, used to heat fat to make soap, and a large open space was specially used to burn wood ash.

Although it looks like a small place, there are not many people, only a few dozen people.

"You can print some patterns on the soap, and find a carpenter to make a few molds, and print the patterns on them when pressing them, so that they look more refined. And the factory can also be expanded, and now there are too few people and too few productions.

This thing is a consumable, and even if the factory building is expanded ten times, it can be sold.

If it really doesn't work, you can find a way to sell it to Daxia."

"Mr. Ren has a trade route to sell it to Daxia?" Tong Zhenye asked.

"Contacting." Ren Baqian has contacted Su Qing through Qinglian, and can then open up another road and send a caravan composed of the Jing clan to Daxia.

But there will inevitably be civil strife in Daxia within one or two years, and it is hard to say what the situation will be like at that time.

In times of troubled times, non-essential products such as soap, glass, and silver mirrors are sold very limited.

However, when Yun Kingdom was captured, it would be a good place to dump goods.

After Ren Baqian transferred to the soap factory, he returned to the palace and handed the soap to the empress: "Your Majesty, this is made by the Ministry of Works."

"Soap?" The empress picked up a piece of soap and looked in her hand. It was straight and right angles, and there were traces left by cutting.

"Yes, I tried it, it was almost the same as expected, and it was better than Izumo's pancreas."

"That's good!" The empress smiled. The days when all the goods were brought by foreign caravans began to fade away.

Then Ren Baqian talked to the Empress about the manufacturing and sales of soaps.

"What do you think?" The first thing the Empress thought of was to ask Ren Baqian for such a question.

"A business department is established, which is responsible for managing the factory and establishing sales channels, and then handed over to the court at a certain proportion at the end of the year, and the other part is used to expand the factory." Ren Baqian said casually.

"Then I can't think of anyone else to do except you." The empress said.

"I don't have this time, but I have an idea. Your Majesty first selects a Si Qing, and then let the two shopkeepers of the caravan, Tang Feng and Gu Ziheng, as their deputy.

Tang Feng and Gu Ziheng are both old men in the caravan. They have a certain understanding of this aspect. As deputys, their abilities are enough.

Now there is only one soap factory, so I use this for them to practice. After they get familiar with it, the others can also start.

In the past, some departments needed to use things, and allocated internally.

In the future, as long as it has product characteristics, it can be classified as the Business Department, and the Ministry of Revenue allocates funds to each department, and each department will purchase it from the Business Department. After the Business Department removes the costs, the money will be paid to the Ministry of Revenue in proportion.

In this way, everything can be on track." Ren Baqiandao.

"This is the business model of the earth, right? But if you do this, the business department will have too much power in the future." The empress held her chin and thought for a while.

Although there is nothing in the business department now, the empress knows that if it were as Ren Baqian said, the business department would inevitably become one of the most powerful departments in Dayao after it develops.

At that time, it was a separate part of the six Da Yao departments, the Ministry of Commerce.

"So, Your Majesty must choose the candidate for this business secretary. Ability and loyalty are indispensable." Ren Baqiandao.
