"Daddy, what are you doing?"

In the courtyard, Lin Mu and Lin Feng were setting up three big iron pots, and yesterday he shared the management of the Lin family's firm, and he was suddenly a lot more relaxed, and now he was finally able to free up his hands to make inventions.

"Daddy wants to make soap with your Uncle Lin Feng, so that the slaves can bathe with soap every day." Lin Mu said to the slaves, and the little girl was looking at them curiously at this time.

When the slave heard this, he clapped his hands happily and shouted, "The slave also needs to help." “

After that, the slave went to carry the bucket on the ground, Lin Mu smiled slightly when he saw it, and let the little girl make trouble on the side.

He naturally will not adopt the way of the Chinese Dynasty for the education of slaves, and tell her what kind of lady and other great truths, it is necessary to let slaves receive modern education since she was a child, so that she can have her own independent thoughts when she grows up.

Let Lin Feng take care of the slaves, don't let the little girl play too much, Lin Mu went back to the bedroom under the pretext of moving materials, and then entered the secret pavilion.

Facing a large pile of empty boxes, Lin Mu smiled, and then he entered S City.

The scene changed, Lin Mu returned to the familiar city, found a car, he walked out of the city along the main road of S city and went straight to the industrial zone located on the periphery of the city, he clearly remembered that there was a national brand soap factory in the industrial zone.

The traffic lights on the road stop at a fixed color, and Lin Mu no longer has to worry about running the red light, and the car is flying fast.

Even though he knew that he was nothing more than a group consciousness, this sense of being physical still gave him the illusion that he had a body outside and a secondary body here.

After walking for more than an hour, Lin Mu arrived at the industrial park, successfully found the soap factory, and entered the factory.

With the resource of soap factory, there is no worry about not being able to make a fortune in the Chinese Dynasty.

However, he is not going to sell the soap from the soap factory directly, after all, if the amount is too large, the night will always be suspected, so the most reliable is to produce it himself, so that no one can question him, and then take some high-quality soap from the soap factory as a treasure.

Thinking of this, he went directly to the material warehouse, and in the face of the warehouse full of caustic soda and flavors, he was ready to take some of it back with him, after all, a bag of caustic soda was enough to produce a lot of soap.

As we all know, one of the two major materials used in the manufacture of soap is grease and caustic soda.

It is not impossible to obtain caustic soda in a place with zero industrial base in the Hua Dynasty, only need to dissolve the natural soda ash ore and lime into lye, react at a temperature of 100 degrees Celsius, and then cool and clarify to obtain liquid caustic soda, which can be further boiled and solidified to obtain a solid caustic soda finished product.

It's just that Jin Bing is about to go south, and he doesn't have much time to slowly engage in caustic soda production, so he can only use urban resources to produce soap for sale first, after all, he now needs a large amount of money to build a military workshop, and at the same time recruit new troops for training.

If anyone doubts the source of caustic soda, he only needs to use the above method to show it, and when this difficulty is over, he will set up a caustic soda industry.

After taking the materials, Lin Mu was about to return to the Secret Pavilion, when he suddenly felt that something was wrong.

After thinking about it, he found that the location of the void on the edge of the city seemed to be wrong, because he actually saw a landmark building bordering the neighboring city and the city of S, and this building was still not available when he came last time.

Out of curiosity, he immediately drove to the edge of the void, and sure enough, as he thought, the position of the void seemed to have expanded, and more land was included in this uninhabited space by the void, but the speed of the void expansion was not fast, and it seemed that it had only expanded two kilometers in so many days, and it was only a few tens of kilometers in a year.

But even so, this is not bad for him, S City is the most developed industrial economic belt in Xia Country, and the larger the area, the richer the resources he can obtain.

In the nineteenth century, when the Hua Dynasty was at its most drastic, he had more leverage, and after agreeing to Duanwang, he thought a lot, and felt that the most effective way to build his own military-industrial empire at present was to use the resources available in the city.

For example, all kinds of high-strength machine tool tools that the Chinese Dynasty cannot manufacture at present, such as the drill bit for drilling the barrel and the boring tool for boring the gun chamber.

With these tools, he was able to have craftsmen build 18th-century hydraulic machine tools, which were cut by rotation, and hydraulic rotation, a structure similar to the principle of a waterwheel, was not a difficult technique in the Chinese Dynasty.

Once the water conservancy locomotive is built, he will be able to use the boring machine to cut the cylinder, the steam engine is not a problem, although this technology is still more than a hundred years behind the current West, but at least it can be used to deal with the Jin people, and so on to overcome this difficulty, he will continue to find a way to use the resources in the city to upgrade the technology, leading the Chinese Dynasty to industrialization.

The Jin people were very dangerous, but for Lin Mu, the Western colonizers were even more dangerous, if the Hua Dynasty did not transform from an agricultural country to an industrialized country, there was no need for the Eight-Nation Alliance, and a change of law would be enough for the Hua Dynasty to toss.

Looking at the dark void, Lin Mu repeatedly carried thirty bags of caustic soda and essence to the secret pavilion, and took more than three hundred iron molds, so that all the things for producing soap were ready.

Carrying a bag of caustic soda out of the secret pavilion, Lin Mu went to the front yard, at this time Lin Feng was boiling the vegetable oil he bought, the technical level of the Hua Dynasty was not inferior to the Ming Dynasty, and there were even many advanced places, so vegetable oil stir-fry These things have become common in the Hua Dynasty.

There are even many oil mills in Jiangning City, and the hawkers of oil sellers can be heard almost every day.

Put the caustic soda down, Lin Mu took out the caustic soda according to the proportion, put it in the water and stirred to make the caustic soda solution, and stirred it evenly.

At the same time, he always paid attention to the oil in the iron pot, and after the oil boiled, he poured the caustic soda solution evenly into the iron pot, and let Lin Feng continue to stir to make the caustic soda and oil fully reflect.

Because the saponification reaction is a long process and needs to be fully saponified, Lin Feng stood by the iron pot with a wooden stick and kept stirring, and after a while, Lin Feng was sweating profusely.

However, Lin Feng didn't seem to feel tired at all, on the contrary, he seemed to be excited to participate in soap making.

Lin Mu was watching the play while holding the slave, and at the same time looking at Lin Feng's quality, this time, he found that Lin Feng was a person who could endure hardships, and he was slightly satisfied in his heart.

After waiting for a while, seeing that the saponification reaction was much worse, Lin Mu asked Lin Feng to add salt solution to it for salting.

With the addition of the salt solution, the soap begins to become cloudy, and finally a curdled white precipitate precipitates.

At this time, Lin Mu asked Lin Feng to add the flavor and continue to stir, and when the soap liquid no longer precipitated, he asked Lin Feng to take out the soap liquid and pour it into the prepared mold to cool, and the first self-produced soap in the Hua Dynasty was born.
