Rise of Rurik

The success of soap making depends greatly on the concentration of lye, and the reason why it is difficult to make it by hand is always that the concentration of alkaline substances is too low.

A dry stick was inserted into the solution, and he carved a knife according to where the water was immersed.

Rurik believed that due to the previous high temperature state, the potassium nitrate from the plant ash in the solution had all turned into potassium nitrite, so it became a very toxic existence to the human body, and its toxicity came from its nitrite radicals. As long as this nitrite comes into contact with fat, it can become alkaline but harmless soap.

Even if he didn't know the specifics of the solution, if he continued to boil it, two-thirds of the water in the urn would be evaporated, and what remained was definitely a high-concentration solution.

What's more, if the urn continues to cool down still, a large amount of crystals will be precipitated in the clay urn.

As long as the water in the urn is lost to only one-third of the length of the stick's flooding point, it is sufficient.

Thus, a fire in the chief priest's house became Rurik's testing ground, and he himself was proudly announcing to all the priests that the greatest action was now.

This glorious declaration is not a serious matter, feeling that it is too late, and the high priest Veria, who is already planning to go to bed, walks up to Rurik on crutches to see what he has to do.

Rurik received the attention of all the priests, but now it seemed that the child was only boiling a jar of brown-yellow water with a special smell.

Because there are still many impurities in this water, they are not the key substances for making soap, but they exude the characteristic burnt smell of charcoal.

The water was boiling, and a lot of steam began to fill the room, which quickly seeped into nature along the gaps in the house.

The priest's long house has a lot of gaps, and it does not have a special chimney. The people inside never consider whether lighting a bonfire indoors will bring poisoning.

None of them have the concept of carbon monoxide poisoning, that is, the flaws in their construction, the large number of unintentional gaps that force the heat to always be lost faster, forcing them to frequently light charcoal fires in the winter, and they are not poisoned.

Therefore, the peculiar smell from the boiling solution gradually dissipated, and inside the brown pottery urn, the water line disappeared at a speed almost visible to the naked eye, leaving cleaning marks on the urn wall.

The current solution is very dangerous, not only because it exists at a high temperature of a hundred degrees, but also because its alkalinity is rapidly increasing. If the potassium nitrite in it becomes pure crystal, it is an extremely dangerous alkaline substance that can corrode rapidly touch its flesh.

But the crystallization of it mixed with other substances is the key to open a new era of human melee.

The priests onlookers hoped to see more fresh things. After staring for a while, they found that they were just pouring water, and gradually lost their interest.

After all, it was very late, and some people didn't want to spend any more time here, so some people went back to their sleeping beds and closed their eyes.

Rurik's work is really just the beginning. In order to get the soil soap out earlier, he must make a decision in his heart. This night is bound to work until dawn, or his spirit will collapse due to excessive exhaustion. .

The water level in the urn continued to drop, and when the lower priests left one after another, Rurik was only accompanied by the loyal Rumia. Not far from the two of them, and Villa, who was waiting for a result, continued to sit on her soft leather cushion, sitting cross-legged and dozing off with eyes closed.

Rurik didn't want to disturb those people. He worked hard, but was disturbed by uninvited guests.

It's really late,

As usual, he should have gone back to his home to sleep.

The son has been staying in the long priest's house, and today the son is still clamoring for a new invention, a kind of baby that can easily wash his hands. Otto didn't interfere with his son's plans at all, until the son didn't come back late at night, an old father's heart couldn't help but worry.

Otto hurriedly broke into the priest to witness, awakening many sleeping people, and also making the dozing Veria suddenly raise his head.

"My leader! You! You shouldn't rush in in such a hurry, what are you going to do?!"

"I..." Otto looked around anxiously, and saw two young figures busy around a bonfire, and his anxious heart calmed down.

"Ah, great priest, I just came to take Rick home to sleep."

"He's right there, don't worry." After that, Villa pointed at him.

There is a strange smell in the air, and Otto's nose is very keen to smell this abnormality. A strange smell came from his son, and together with his servant, the pottery urn that the two children were playing with caught his attention.

"Rurik, what are you doing?"

"I know you're here, Dad," Rurik said perfunctorily.

"Is this the pottery urn? You said you were going to do something special, did you get results?"

"That's it." Rurik was very proud and wanted to introduce Otto Haosheng. But on second thought, the lengthy description is nonsense, and only the real thing is the last word.

Rurik thought for a while, and muttered, "I'm not going back today, I'm going to do a great thing. Dad, go back and tell Mom that when it's dawn tomorrow, I'll definitely take out my invention."

But Otto could hear that his son was announcing that he would stay up all night.

"Ah? My child, you are not a hunter yet. You don't need to stay up all night. You are too young, I believe you will succeed. Now it is more appropriate for me to carry you back to sleep."

"No! My work has reached a critical moment." Rurik increased his voice.

"Perhaps, the work can be entrusted to your servant. Listen, servants are made for this." After speaking, Otto gave the ignorant Rumia a wink.

Otto's idea was exchanged for Rurik's stern refusal of course.

He thought to himself, I am an old guy with a mental age of forty years old. It's hard enough to pretend to be a seven-year-old child and pretend to be naive. Does the so-called adult still forcibly deprive a child of the right to play with toys.

Ah, this toy is extremely dangerous lye... is this a toy?

No, Rumia doesn't know anything at all. She will do many things for me in the future, as long as I have to teach her the first time.

Rurik stomped his feet, "Dad, you must believe me this time, you will get a huge fortune because of the right choice tonight."

"Wealth? My child, you are my greatest wealth." Otto squatted down, his eyes converged, he pinched his son's soft face as if he was coaxing a child, "You are only seven years old, in the future you will With the challenges of a real man, of course, now you really need to go to bed."

"No! I will never be a man who can only row and fight, I have to become a wise man!" Rurik pointed to his brain in excitement, "I will use my strength to become the leader, and I will use my brain to make Everyone gets rich. Dad, you have to follow my advice, don't you believe in your son? Or do you... do you think I'm the same as the other kids?"

A question about the depths of the soul stunned Otto.

Ask yourself, when this child is in the snow under the background light, holding his own "Destroyer" sword and protecting his current servant, this child is indeed very different from other little boys.

At that moment, Rurik was not a child at all, as if possessed by some great being.

Seeing that his son was so stubborn, he was afraid that he would be forced to run away like a lamb, and the child could not sleep peacefully on the soft leather blanket.

Otto didn't speak any more and left angrily.

After the dispute was over, the huge room was quiet again.

Villa can close her eyes again with peace of mind, she knows that no one will disturb her dream tonight. She was also curious about Rurik's invention, and after listening to the child's simple description, the invention was a mixture of seal oil and yellow water in an urn. No one in the tribe had attempted this until Rurik explained it.

Even a priest who often boils oil, even when he was young, did not have such a whim. Perhaps, the convergence of the two will indeed happen a miracle, but that will not give the elderly Villar greater mental stimulation. She is too old and has a low appetite for novelty.

Villa returned to his compartment, lay in the sleeping nest made of animal skins, and soon fell asleep.

The hall of the long priest's house suddenly became empty, Rurik looked at the quiet scene around him, and couldn't help comforting Rumia, who couldn't help yawning.

"Ah, now it's just the two of us."

"Rurik, you? Go on?"

"Yes, I need your help next. My sister, you and I don't have to rest tonight, because I promised Dad that I will produce results."

Lumia understood the meaning, she did not refuse, and she had no right to refuse, she could only follow the master's orders with all her might.

It's not a hard command to take, it's even fun.

Now, the scorched pottery urn rests, and the hot solution inside is gradually cooling. Rurik still didn't know the concentration of potassium nitrite in the solution. Seeing that the water immersion position of the wooden stick had reached the target value, it must have had enough concentration. He believes that the saponification reaction can start as long as it reaches a critical value, and the problem after that is only the relationship between the concentration of the solution and the hardness of the soap.

In fact, Rurik is also the first time to make soil soap. The principle is as simple as that. To create exquisite soap, and even to create soap with exquisite and charming aroma, that is his ultimate desire in this regard.

Because as long as it is successful, the people of the tribe use it to wipe and clean the body, and the fragrance replaces the inherent sweat odor, and even the bad body odor. Especially those who are happy to spruce up their appearance, they will pay huge sums of money for a bar of soap that leaves them clean and scented.

Rumia hung the pottery urn full of seal grease on the bonfire. Gradually, the semi-solidified grease gradually turned into a pure liquid state.

"That's all it takes? Does it need to be hotter?" she asked Rurik.

Rurik stretched out his small hand and tried to touch the liquefied oil, a strong pain felt on his hand.

"Enough is enough, if it boils over our work will be difficult."

The saponification reaction requires the right temperature, and there is no doubt that the boiling oil is simply overheated.

He ordered Rumia to heat the grease again, and then let her remove the pottery urn.

"Rumia, the most important thing is now, you avoid it for now."

"Why? I will help you well."

"No. You observe my movements for a while, and you have to remember my movements. In the future, you will do these things yourself."

"I will."

Rumia stepped aside with an uneasy heart, still staring at Rurik's movements.

There is a saying that more oil is added with more water and more oil. If you know the exact concentration of the key materials in the solution, as well as the exact mass of all the materials, with some mathematical calculations, Rurik can master the blending ratio of all the substances in advance. In desperation, he can only use a very stupid method, which is to use a wooden spoon to pour the hot liquid oil directly into the plant ash precipitation liquid of unknown concentration.

The first spoonful of oil is poured in, and the saponification reaction occurs instantly.

The clear, yellowish oil suddenly changed color, and there were still some tiny air bubbles.

He continued to pour the oil, and finally poured all the oil in the pottery urn into it.

But grease and water are naturally repelled, and grease is only particularly interested in alkaline substances dissolved in water.

"Ah, great. If I pour the oil slowly, there won't be a violent chemical reaction. Next..." Rurik paused, and beckoned to Rumia, who was observing carefully with a satisfied smile, "You Come here, it's your job next."

Rumia's current status is a servant, if she has a lot of idle time, it will definitely cause criticism from others.

Rurik really needs such a sister to do a lot of things. She is only seven when she is ten years old. Although her mental age is completely different, a seven-year-old child is frantically stirring the mixture of oil and water with a wooden stick, even if it is quite strong, You will be exhausted in no time.

"Rumia, take a stick, and then you'll stir this pottery urn. It's going to be a tiring process, and you have to do it in order to make a treasure."

Afraid that she didn't understand the Norse language well, Rurik explained more slowly, and explained the key words in the newly learned ancient Sami language.

"I'll stir hard and I'll make you happy."

Rumia didn't have any complaints. It was an honor to be a servant to be able to do great things for her "younger brother", otherwise that sister would really be ashamed.

She stirred the material in the pottery urn with a selfless heroic attitude, and soon, the change of the material surpassed her cognition.

The saponification reaction had fully begun, and Rurik hung his head in satisfaction as he watched the chemical changes taking place.

The pale-yellow, rather transparent oil had changed its properties, and it was becoming creamy and viscous. Because of the color of the plant ash precipitation, the mixture in the urn turned into a brownish-yellow paste, accompanied by a special smell, just like normal soap.

The pervasive smell was exactly what Rurik wanted to smell.

His heart was very excited, and he used plant ash and seal oil to create soap in ancient northern Europe thousands of years ago.

He was very sure that the substance in the urn was soap, but the dissolved alkaline substance was quickly combining with the fatty acid molecules because of Rumia's selfless stirring.

A large amount of water needs to be removed, but it should not be completely removed.

Soaps can be as hard as bricks in the sun, and their water content can be very low, and even such soaps feel terrible to use.

Of course, too much water will not work. If the soap bar is too soft, there are relatively few active ingredients, and it will not be durable.

The soap base liquid has been completed, and it is still very hot. Even though Rumia's arm is already very sore, the heat of the paste can instantly burn the flesh that touches it.

"Rumia, are you tired?"

"Not tired! I can still persevere."

In fact, she must be very tired. The ten-year-old girl's forehead was covered with sweat, and the movements of her hands slowed down.

"Stir slowly now." Rurik patted her on the shoulder, but was taken as an encouragement by the girl, so he gritted his teeth and stirred desperately.

"I really can't do anything about you. Well, then you won't be able to go pasture grazing tomorrow because you're too tired. Well, I'll also entrust you with a big job in the future. It's enough to let others do the grazing for me." Rick went to get the small wooden box prepared in advance.
