Regarding the establishment of official files, Zhu Yijun quickly arranged it to Zhang Jing as the focus of the next work of the East Factory. Although it was time-consuming and labor-intensive, Zhu Yijun attached great importance to this matter. He also believed that after the matter was completed, it would bring him a lot of benefits.

After arranging the matter here, Zhu Yijun began to care about Chen Ju's affairs again.

The task assigned by Zhu Yijun to Chen Ju is also very simple. To put it bluntly, it is to support the war of starting a new battle.

Although the military battle situation is an empty yamen, it is still famous and has fewer concerns when doing things. Zhu Yijun also likes this and does not start a new business. Relatively speaking, the military battle situation will not be too resistant to others.

It’s just that Zhu Yijun asked Chen Ju to go, but he did not give Chen Ju financial support.

Whether it is now or later generations, you can't play with it without money. Zhu Yijun sent Chen Ju over, actually just to make him familiar with the military battle situation and adapt to it before starting his formal work.

When Chen Ju learned that Zhu Yijun was coming to the military battle, he had been waiting here long ago.

As an ordinary eunuch in the palace, Chen Ju was very excited and excited when he was valued by Zhu Yijun, and vowed to achieve something. But after coming to the military battle, Chen Ju was stunned.

If you want money but no money, no one, the military battle situation is just a blank air. What should I do if I ask myself?

After thoroughly sorting out the military battle situation, Chen Ju's heart was almost depressed. With such conditions, let alone completing the tasks assigned by the emperor, it would be a problem to make a little money! You can't get some weapons and armor to sell them, right?

First, Chen Ju doesn’t have the courage to do so, and secondly, there is no channel! Don’t sell it here, and someone will report it there.

After hearing that the emperor had arrived, Chen Ju was naturally very nervous. In Chen Ju's opinion, he was afraid that this time he would disappoint the emperor.

After Zhu Yijun came, accompanied by Chen Ju, he visited the entire military battle and asked many questions. He found that Chen Ju answered these questions in a good manner, which was well known to him. Zhu Yijun nodded with satisfaction.

Dongchang has long reported Chen Ju’s affairs to himself. Although Chen Ju was thinking of a solution during this period, he did not do anything bad to the rules, which made Zhu Yijun very happy. These are enough. As for whether Chen Ju did it or not, Zhu Yijun didn’t care so much.

"Chen Ju, you did a good job!" Zhu Yijun looked at Chen Ju with a smile and said.

"I have to bear the great kindness of the emperor, I am, I am!" Chen Ju stood up a little uneasy and said quickly.

Zhu Yijun waved his hand and said with a smile: "You did a good job, I am very satisfied. I came here today to give you a way to make money." After that, Zhu Yijun shook his hands and left, but someone left a large wooden barrel.

"Do you know what's here?" Zhu Yijun asked with a smile, pointing at the big wooden barrel.

"I don't know!" Chen Ju shook his head quickly.

Zhu Yijun felt a little bad, shook his head, reached out to open the lid of the wooden barrel, and said with a smile: "There is a bucket of lard in this place. You can rely on it to make money in the future. Learn it well, I will only teach you once."

Originally, Zhu Yijun wanted to draw a picture for Chen Ju to do it himself, but later, after thinking about it, he still felt that it was more reliable to teach it himself and save some time.

What Zhu Yijun needs to do is saponification reaction, dissolve quicklime in water, make lime water, and then pour baking soda into it. Baking soda, which was used in later generations to steam buns and buns, is sodium bicarbonate. After reacting with the lime solution, it produces calcium carbonate precipitates and a clear upper solution.

These clear liquids are sodium hydroxide, which is what Zhu Yijun needs.

Many people don’t know about sodium hydroxide, but when it comes to another name, many people will know about it, that is, huo alkali, which is an important industrial raw material and is extremely corrosive.

Zhu Yijun skimmed out the liquid with a glass spoon, for fear that a little bit of it would spill out. Once the alkali touched the skin, it would cause serious burns. Zhu Yijun was very careful about these things.

Zhu Yijun took a risk the last time he prepared sodium cyanide and never did it again since then.

Pour the scooped sodium hydroxide solution into a hot oil pan and stir thoroughly, and a saponification reaction will occur.

Zhu Yijun looked at Chen Ju who was burning fire beside him and said with a smile: "Don't be careful, I will give you a book with detailed records on it. You can just watch it now and just write down the general steps."

Although Zhu Yijun said this, Chen Ju still didn't dare to be careless. This was taught by the emperor. If he forgot about his death, he would have to die!

Zhu Yijun stirred the oil pan evenly, and the next thing was to wait. During this process, you need to add a few drops of brine, which is used to order the brine for tofu. There is no saying that if you put the tofu in the brine, you can get the tofu in the brine.

It took not long for the time, and the lard in the pot had already begun to saponify, and the top layer of oily yellow soap began to gradually solidify.

Zhu Yijun quickly said to Chen Ju: "Look, take advantage of this time, take out the purest soap on the surface and put it in rouge powder. This is the first thing we make money, it is called soap."

Lard soap that has not been treated will have a smell of oil. Even after making the soap, no one is willing to use it to make it smell like lard.

Although adding rouge powder can cover up this taste, it is not the best choice. The best choice is of course to use floral essential oil, but things need to be made from generation to generation, and they need to be updated from generation to generation to make money!

This is the marketing method.

After making the soap, there are still some turbid soap and the bottom layer of alkaline waste liquid left in the pot.

The middle layer of turbidity was skimmed out, and Zhu Yijun put them alone in a basin. The ingredients here were mainly lard and impurities that were completely reacted, and a small amount of soap. Zhu Yijun added the mixed brine to it and stirred vigorously to heat it.

Soon, the lard in the pot changed again and gradually solidified.

"This is our second money-making thing, this is wax, candles used for lighting!"

Chen Ju was almost stunned. He didn't know that it was just a bucket of lard. Why did the emperor make so many things in different ways? He didn't know what the soap in front was made of, but he knew the candle!

The best candle now is butter candles, but the Ming Dynasty prohibited the slaughter of plowing oxen, and there are no butter candles on the market to sell.

What Chen Ju didn't know was the candle made from animal fat. Because there was glycerin inside, the flame was smoked when burning, and the smell was bad. If you switch to stearic acid to make a candle, not only will the flame be bright when burning, but there will be almost no black smoke and will not pollute the air.

This is what Zhu Yijun did. The candles produced in this way are not only smoke-free, burn well, but also cheap.

For nobles and rich people, smoke-free is enough. Whether it is oil lamps or grease candles at night, they are all choking. Once this candle is on the market, it will definitely be very popular.
