A special forces soldier traveled through time and space to become a genius of literature and martia

It was noon, and the yamen runners brought in lunch. It was a table of ordinary home-cooked dishes. Yuan Ying was the last one to sit down. He served lunch to Old Man Hua before eating it himself.

Eating the dishes on the table, each one had a bitter taste, similar to the taste I had at the inn last time.

Yuan Ying was very puzzled and couldn't help asking Murong Xuanyi: "Why does every dish taste a bit bitter?"

Murong Xuanyi looked at him deeply and said, "The production process of Daxia salt is crude. Fine salt is imported from Yindu. Because fine salt is expensive, it is only used by dignitaries. Ordinary people can only eat local coarse salt. Coarse salt has this bitter taste."

When Murong Xuanyi heard Yuan Ying ask this, it was obvious that he had never eaten coarse salt, but from his clothes, he didn't look like a noble. Was he from Yin? His accent didn't sound like that either. Murong Xuanyi was puzzled.

Yuan Ying couldn't believe it. A country as big as Daxia couldn't even make fine salt. How difficult is it to refine fine salt? It's something that children who have studied high school chemistry in the 21st century can do.

The impurities contained in crude salt mainly include magnesium chloride, sodium sulfate, calcium sulfate and insoluble substances, etc. Thinking of such impurities, eating them will only make the patient's diarrhea worse.

She said to Murong Xuanyi: "Your Highness, patients with severe diarrhea cannot consume coarse salt, otherwise it will aggravate their condition."

Murong Xuanyi said calmly: "I will find a way to transfer some fine salt from somewhere else as soon as possible."

Yuan Ying didn't say anything either, just ate the somewhat bitter dish in silence.

After lunch, everyone went back to their rooms to work on their tasks.

Yuan Ying knocked on Murong Xuanyi's door. Fang Yang was grinding ink while Murong Xuanyi was writing something at the desk.

Seeing Yuan Ying coming in, he asked, "What's the matter?"

Yuan Ying said directly without beating around the bush: "Your Majesty, please arrange for someone to get some coarse salt so that I can extract fine salt."

As soon as Yuan Ying said this, Fang Yang and Jiang Chong looked at Yuan Ying in surprise. Murong Xuanyi was so shocked that his hand holding the pen trembled, and the ink dripped directly onto the rice paper, forming an ink flower.

Yuan Ying looked at their surprised expressions and said, "You don't believe me? If I had coarse salt, I would show it to you right now."

Murong Xuanyi excitedly walked up to Yuan Ying from his chair and said, "Are you serious? If you can refine fine salt, I promise you a lifetime of prosperity."

Yuan Ying nodded and said, "It is absolutely true, but there is a condition."

"What conditions? Just tell me." If Daxia could master the refining of fine salt, it would no longer be afraid of Yin blocking Daxia's lifeline. Don't mention one condition, even a hundred of them must be agreed to.

Yuan Ying looked at the other two and said, "I can only tell you the refining method. I don't want a third person to know that I can refine fine salt, at least not now."

Yuan Ying was a cautious person. If everyone knew that she could refine fine salt, some people would take risks driven by profit. Then they would be in danger of being killed. She wanted to do something practical for the ancients, but she didn't want to get into trouble.

Murong Xuanyi didn't expect Yuan Ying's condition to be this: "Okay, I promise you."

He immediately said to his two guards: "If you leak it, my three clans will be exterminated."

Fang Yang and Jiang Chong hurriedly said, "Master, we dare not!"

All the doctors in the West Wing went to the front line to fight the epidemic, and Lord Cui and Lord Zhang were also sent away by Murong Xuanyi. Old Man Hua took the pheasant and ran to some corner to eat it alone.

Soon Fang Yang and Jiang Chong prepared a large sack of coarse salt, two large pots, gauze, river sand, charcoal and wood ash.

The purification of crude salt is not too complicated. There are two methods. One is to use wood ash, and the other is to use lime milk. The fine salt extracted from wood ash is not as white as the fine salt extracted from lime milk. But there is no lime milk at the moment, so we can only use wood ash. Anyway, it is edible.

Common impurities in crude salt are divided into insoluble impurities and soluble impurities. The first step is to filter out the insoluble impurities with fine sand and charcoal. Then add plant ash and let it settle in the sun, which is enough to remove the soluble impurities.

Although there are still some impurities in the salt after this kind of filtration, it is undoubtedly much better than before. After repeated refining, which took a whole afternoon, when night fell.

As the brine in the pot gradually turned into pure white crystals, Yuan Ying's mouth couldn't help but smile.

"It's done!"

This was also her first time to actually extract fine salt. She couldn't help but feel excited in her eyes.

Although the refined salt extracted from hundreds of kilograms of crude salt looked to be less than 21 kilograms, and not as white as the finished salt of the st century, it was already finer and whiter than the salt produced in Yin country.

Murong Xuanyi looked at the fine salt in the pot and couldn't help but feel excited. This half-day's effort was something that Daxia people could hardly achieve in their lifetime. How could he not be excited?

Fang Yang, Jiang Chong and others were also very shocked. They saw with their own eyes that the brown-yellow coarse salt gradually turned into pure white fine salt.

If everything before their eyes was not so real, they would feel like they were dreaming.

In the minds of Daxia people, fine salt and coarse salt are two different species. In this era, coarse salt and fine salt are simply a world of difference. Coarse salt is only about 100 coins per bucket, while the price of fine salt is more than 100 times.

Murong Xuanyi memorized all the steps in his mind, and an inappropriate idea popped up in his mind. If he submitted the method of making fine salt to the court, would Yuan Ying agree...

"Yuan Ying, I want to submit this method of making fine salt to the court. Do you think it is okay..."

"Of course. Salt is a serious matter. If the method of refining fine salt can be widely used, it will be a great blessing for the country and the people. Just don't mention me." Since Yuan Ying planned to teach him, he wanted the people to be able to afford fine salt.

Murong Xuanyi couldn't help but take a deep look at Yuan Ying. Who was he? He could refine fine salt, and he was from Yin? Then why did he tell him the refining method? Now he was even more confused. He couldn't wait to know his background.

After dinner, Yuan Ying returned to his room and prepared to write down the two methods of extracting crude salt and give them to Murong Xuanyi.

As she was sitting at the table writing furiously, she suddenly felt a warm current under her body.

Yuan Ying suddenly felt something was wrong. He had been having a dull stomachache for the past two days. Could it be that he was about to have his period?

Yuan Ying quickly took out a tampon from his bag and went to the toilet.

It was just as she expected.

Murong Xuanyi saw Yuan Ying walking outside listlessly like an eggplant hit by frost.

He wanted to say hello, but Yuan Ying acted as if he didn't see him and went straight back to his room.

Yuan Ying returned to her room in frustration and opened all the tampons in her bag. There were still three left. What should she do when these three are used up? Use wood ash? She doesn't know how to do it either. Ahhhh... She rubbed her hair angrily.

Is there any way to avoid having your period?

I don't know if it's because of the pills I took. This time, my stomach hurt several times more than before. Yuan Ying was in unbearable pain all night, tossing and turning in bed. He even went to the toilet halfway. I couldn't sleep, so I sat at the table and wrote and drew to distract myself.

Murong Xuanyi next door was in a state of excitement because of the fine salt incident and couldn't sleep all night. He heard everything that happened on Yuan Ying's side clearly.
