Jia Rong thought of the practice of soap, which is in the chemistry textbook of junior high school, the principle is very simple, and in the future, Shijie Jia Rong will also do it himself.

Came to the Han Dynasty, but did not have enough confidence to make soap, the main reason is the lack of raw materials, such as caustic soda, which cannot be found at all, but you can choose to use plant ash instead, the grease is easy to find, and it depends on the will of God whether it succeeds or not.

Jia Rong instructed Zhang Wei to immediately go to the craftsman's workshop to make a large pot, and then asked the soldiers to go to the market to buy a lot of animal fat, which was relatively simple in comparison.

In a closed hut, Blacksmith Liu was working hard to light the fire, Jia Rong held a big soup spoon in his left hand, constantly stirring, and his right hand kept adding something to the pot, his expression was very focused, the pot was constantly boiling, the house was like a steam room in later generations, outside the hut, Zhang Wei took five or six soldiers to guard it closely.

Jia Rong, who had been busy all morning, also realized this, and decisively ordered the soldiers to dig down the big windows on the walls, and when the wind blew, the heat in the house dissipated a lot.

The rice paper was thrown into the raging flames by Jia Rong as garbage, and Liu Blacksmith was distressed when he saw it.

The day passed quickly, and Jia Rong and Liu Blacksmith spent the rest of the time in this closed hut except for eating.

Jia Rong's head, face, and clothes were covered with a thick layer of black smoke, and from a distance, he looked like he had fled from Africa.

Jia Rong knew that the clear proportions of soap were just the difference in raw materials, resulting in these proportions being completely inaccurate, and what Jia Rong did was to experiment again and again, recording the proportions until he succeeded, Jia Rong didn't remember how many times he had failed, but each time the proportions were recorded by Jia Rong in symbols that the Han Dynasty people could not understand, and after a day, Jia Rong was sure that the soap would be made.

Three days later, when Jia Rong came out of the closed hut with a dusty face, he felt for the first time that the sun was so bright, the shijie was so big, and the spring breeze was so warm.

Finally succeeded, after unremitting efforts, the soap was finally made, but the pot in front of him was still a synthesis of glycerin and soap, as long as it was decomposed, Jia Rong was the inventor of the Han Dynasty and made the first soap.

Jia Rong happily took a hot bath, washed away the dirt of the past three days, and studied the soap, Jia Rong was excited, with soap, it means that there will be a lot of money.

In fact, the things used by ancient people to wash clothes and bathe are similar to soap, they call it pancreas, which is finely mashed with animal internal organs, and then completed through a series of processing.

Blacksmith Liu circled around the cauldron that was moved by the soldiers into the courtyard three times, but he still didn't find anything strange about the pot, it was just a pot of viscous things, could it be that these were the hard work of the past few days, but looking at the excitement on Jia Rong's face, Blacksmith Liu felt that things were not so simple.

A bucket of salt water was brought up, Jia Rong carefully sprinkled the salt water in the pot, and only then stopped and stood aside when it was almost done, chatting with a few soldiers, the soldiers of the Xiliang Army knew that Jia Rong had the habit of chatting with soldiers, and the soldiers were also happy to chat with Jia Rong, and often some problems that they felt unfair would be solved soon after telling Jia Rong through chatting.

Half an hour later, the things in the pot have completely reacted, Jia Rong gently took out a part of the upper layer of things, put it next to his nose and smelled it, did not smell any fragrance, but the fresh smell of soap was a shock to Jia Rong's spirit, no fragrance, naturally it will not be fragrant, for the first time to create things, Jia Rong looked at the more pleasing to the eye, he knew that he would learn more things in later generations, and came to ancient times to engage in scientific creation, and by the way, he built a Han Academy of Sciences, like a Mauser gun, Gatling or something made a large number of them, and he was worried that he couldn't unify the world, suddenly, Jia Rong remembered something, his brows furrowed tightly, and it took a long time before he slowly relaxed.

As witnesses to this invention, several soldiers present and Blacksmith Liu were honored to be given a small piece.

It is not enough to have a finished product, but also to be effective is the most important thing, a soldier quickly called a basin of water, Jia Rong washed it, it felt very good, not only the hands were clean, but there was a faint freshness left on it, and the washed hands also felt slippery.

The rest of the people did the same, and soon they were shocked by this small thing, because its cleaning effect was so obvious, Liu Blacksmith's hands were black, and when they were washed by this magical thing, they were immediately clean, but the water he had washed turned black.

After the joy, Blacksmith Liu immediately realized the value of the thing in front of him, as the leader of the craftsman's workshop for so long, if he didn't even have this vision, I am afraid that he would have been kicked down by Jia Rong a long time ago, and he felt sorry for wasting such a good piece of things just now.

Jia Rong once again gave a death order: "No one can say anything about the matter here, even if the closest people ask about it, otherwise they will be endlessly pursued and killed by the Xiliang Army!" ”

The cold tone made several people present shudder, Blacksmith Liu repeatedly said that he would never say anything about it, and for a few soldiers, it was not so important, they didn't know how this thing was made at all, and their loyalty Jia Rong still believed it very much.

"Blacksmith Liu, from now on, all the blacksmiths in the craftsman's workshop must be registered one by one when they go home, including how long this blacksmith has been back, is it really home, understand?"

"Yes!" Blacksmith Liu replied loudly.

As expected, the soap will be welcomed by all consumers as soon as it comes out, and the price will have to be discussed with Su Shuang, after all, he is the real businessman, and the substance that is decomposed by salt water is glycerin, which is also a very practical item, and it can effectively prevent freezing and cracking on the hands and faces in winter.

With soap, Jia Rong is full of confidence, and he will not be as passive as before when talking to Su Shuang.

For a time, all the grease in Lingzhou City was ordered to be purchased by Jia Rong, in order to avoid the calculation of people with intentions, Jia Rong specially ordered the soldiers to buy many irrelevant items, confusing the public, I believe that no matter how smart the people of the Han are, it is difficult to imitate them for a while.

By the time they copied it, the fame of the soap they made had already spread, and they would only make a small amount of money at best.

The craftsman's workshop deliberately divided ten small houses for making soap, dozens of soldiers guarded here day and night, Jia Rong even handed over a copy of the soap making method to Liu Blacksmith, suspects do not need to use people, since these blacksmiths are willing to follow themselves all the way to Lingzhou, loyalty is still worth considering.

Especially Blacksmith Liu, when he knew that this was the production method of magical things, he fell to the ground excitedly, thinking that he was a small blacksmith in Beidi County, it was Jia Rong's step-by-step promotion that led to him today, how not to be grateful, the value of the formula in his hand Blacksmith Liu also understands, and it is not an exaggeration to describe it as valuable.

After the soap is produced, it will only become a consumer product for the upper class of society for the time being, in order to divide the grade, Jia Rong added flavor to some soap, and the soap naturally became soap, compared with soap, soap is more precious, and it makes people feel more face-saving and more noble.

When Su Shuang really couldn't wait, Jia Rong appeared, Lingzhou City really didn't have anything to visit, Su Shuang tasted all the food and drink, Su Shuang felt that the border county really couldn't be compared with the county town in the mainland, whether it was wine or food, it was inferior more than a notch, except that the folk customs were a little stronger.

"Brother Su has been doing for a few days?" Jia Rong looked at Su Shuang's panda eyes and asked.

Su Shuanglang laughed loudly: "Lingzhou City is really a good place, located on the border, the people are bold, and it is a great honor for Zhiyuan to serve here." For Jia Rong's immortal paintings, Su Shuang felt that he could endure anything, and his words against his heart became very smooth.

Although Jia Rong has stayed at home in the craftsman's workshop these days, he still knows all the situations in Lingzhou well, and said with a smile: "Since Brother Su lives very well here, let's stay, although Lingzhou is poor, Brother Su's food and clothing can still be afforded." ”

Su Shuang hurriedly said: "Zhiyuan's kindness is appreciated by my brother's heart, but my father specially asked me to go back early before leaving, my father's fate is difficult to disobey, and I hope Zhiyuan will forgive me." ”

Jia Rong smiled faintly and took the lead in walking into the county office.

"I don't know what I said to Brother Su a few days ago, how did you think about it?"

Su Shuang said with a look of embarrassment: "I can't help my brother!" The family's assets are still in charge of the father, and even if he wants to help his brother, he can't help. ”

Su Huang's dodging gaze naturally did not escape Jia Rong's eyes, and he smiled disapprerovitically: "It's still the same sentence as before, Brother Su shouldn't make a conclusion early!" ”

Su Shuang wanted to say something more, seeing the confident look on Jia Rong's face, he stopped talking, and looked at Jia Rong quietly, in fact, it is not impossible for the Su family to help Jia Rong, the key is that Jia Rong has to come up with enough benefits, no profit can not be early, after all, there are only so many saints.

Jia Rong mysteriously took out a small piece of item from his arms and handed it to Su Shuang's hand, "Brother Su, look at what this is?" ”

I couldn't name this item when I saw it with Su Shuang's resume, I just felt that it was very slippery to start with, and there was nothing special about the appearance, so I asked: "I don't know what kind of artifact this is?" ”

Jia Rong smiled mysteriously, handed the haode ink that had been prepared to Su Shuang, and then used a brush to draw a little on Su Shuang's hand.

"Brother Su will know by washing his hands with this thing and trying it." Jia Rong said with a smile.

The soldier had already brought a basin of water, and Su Shuang carefully washed his hands under Jia Rong's guidance.

Jia Rong clearly saw that Su Shuang's expression gradually turned from surprise to shock.
