The kitchen was in the corner of the military camp. The fat and fat chef of the Huotou Army was shocked when he saw the general coming and hurriedly saluted.

Peng Yue waved his hand: "You are busy with yours!"

He followed Xu Yan into the kitchen, where several large pots were supported, and there were chopping boards next to them, with a pile of bottles and jars on them.

Xu Yan turned around and found that it was a seasoning, including pepper, cinnamon, salt, oil, etc. He took out a piece of brown crystal from a clay pot. It was very hard to pinch and it smelled a little pungent.

This is the coarse salt eaten by the ancients. Xu Yan had seen it in the mountain village. At first, he thought it was slag, but he talked about it for a long time.

"It is better to eat less coarse salt, because there are too many impurities, such as toxic substances such as nitrate and phosphorus. Eating too much is not good for the body!"

Peng Yue was puzzled: "I have been eating in the camp, but I haven't seen anything wrong!"

"It won't happen in a short period of time, but it will damage the internal organs after years of accumulation. This should be the salt you can eat!"

Xu Yan took out a cloth bag from his arms, Peng Yue took it, saw the white crystal inside, and said in surprise: "This is the best salt, where did you get it?"

Of course, it was brought from the medicine house. Liu Heiqi would deliver things every once in a while, including fine salt.

But I can't say anything about the bandits, Xu Yan said: "There is a salt mine in the deep mountains. My master and I mine some every year, bring them back to our residence, and extract edible salt from it. The coarse salt you eat can be turned into fine salt as long as you process it a little!"

"What you said is true?" Peng Yue widened his eyes.

"Of course, how dare you deceive the general?"

Peng Yue looked overjoyed and pulled him and said, "Hurry, you can practice the extraction method now. Just say whatever you need!"

"But I still have to cook..."

"Let's do it later!" Peng Yue said impatiently.

The method of purifying coarse salt is very simple, and there are only a few things needed, charcoal, gauze, funnel, and wooden barrel.

First, smash the coarse salt and pour it into the wooden barrel, add water and stir, filter the precipitate with gauze, and then use charcoal to detoxify.

Finally, the light green liquid is left, pour it into an iron pot and boil it until the water is evaporated, and edible salt particles will precipitate at the bottom of the pot.

A group of people surrounded the iron pot and were eager to see it. Peng Yue personally added firewood, looking forward to the miracle.

Xu Yan was so hungry that he put his chest on his back. After doing it, he stopped caring about them, but went into the kitchen to search for ingredients.

A ball of hot noodles is just used to make scallion pancakes.

Knead the dough into a ball, roll it out and apply oil and salt, sprinkle with chopped green onion, then roll it out, pour oil into the pot, and after the oil is hot, spread the cakes, so that you can spread five or six at once.

In addition, half a piece of pork was found, Xu Yan chopped it into large pieces with a knife, threw it into a pot and cooked it. The green onion, ginger, garlic and garlic can be used to remove the fishy smell, the pepper and salt can be used to enhance the flavor, as well as Xu Yan's homemade seasonings, star anise cinnamon, etc.

The fat chef stared at his round eyes and looked at him intently. This is a skill, and he has benefited greatly from learning it.

The cake that was first released from the pot was half cool and not hot, spread it on the chopping board, and Xu Yan picked up a large piece of meat from the pot and placed it on the cake. The meat was cooked soft and rotten, with an attractive fragrance.

Bring the cake a roll and bite it with the meat, full of happiness.

When they smelled the fragrance, Peng Yue and the others came, staring at the pot with their eyes shining, and kept swallowing.

"Eat, why are you standing there?" Xu Yan smiled.

Everyone was delighted and rushed forward, eating voraciously. The fat chef who helped to burn the fire became anxious and waved his hands and shouted, "Leave one for me, don't grab it!"

More than a dozen cakes were quickly snatched up, and after eating them, they were still unsatisfied. At this time, the role of a fat chef was shown. He learned very quickly and called a few hot-headed soldiers to help him. He opened three pots at once and made scallion oil pancakes continuously until everyone was over.

Xu Yan walked out of the kitchen. It was already dark and a waning moon hung in the sky.

The water in the iron pot was boiled dry. Xu Yan lifted the lid and saw a thick layer of salt crystal precipitated from the bottom of the pot. He pinched it and tasted it. It had no bitterness at all, which was better than the fine salt he ate!

Peng Yue was obviously aware of the goods and said in shock: "This is green salt, the price is more expensive than fine salt. Oh my God! We're sending it now!"

One pound of coarse salt can be made into half a pound of green salt. Once sold, it will be a hundred times the profit.

Everyone fell into ecstasy, which was the shock brought by wealth.

Of course, Xu Yan knew the benefits of selling salt, but in ancient times, the official business of salt and iron was needed to obtain an official license if he wanted to sell it.

He didn't want to get involved in this, because it was too dangerous, so he passed the technology to Peng Yue to gain favor.

Peng Yue had two choices: one was to present the purification method to the court and get rewards, and the other was to secretly sell salt in private and obtain huge profits.

I don't know how he would choose?

At night, Xu Yan moved into the military camp. Peng Yue specially arranged a tent for him and slept until dawn. Dr. Zheng came to call him that he would have surgery today.

After breakfast, he followed Dr. Zheng to the medical area. The operation was performed by Dr. Zheng, who was the one who was next to him.

The pain caused by amputation is enough to cause collapse, so before the operation, the patient needs to undergo anesthesia, but now there is no anesthetic, and the amnesia that Xu Yan has refined before has too many toxic side effects and cannot be used.

After thinking about it, I could only drink and get drunk.

After drinking two jars of strong wine in a row, the soldier died of drunkenness and the operation officially began.

The knives used were soaked in alcohol in advance, including the hands of the two people, and they washed them with alcohol. Xu Yan also asked someone to make a mask and put them on. Dr. Zheng felt it was a bit strange, but he didn't stop him.

Cut it accurately along the incision agreed in advance, because the thighs have been tied with a soft towel in advance, so there is not much bleeding.

Dr. Zheng's hands were very stable, thanks to his years of fighting with the army and having seen too many bloody scenes. Now he is calm. However, Xu Yan couldn't stand the bloody look, but he could only bear it.

The operation lasted until noon and the process went very smoothly. The cut off calves were put into thick medicine, and the blood flow rate was significantly slowed down, which made both of them breathe a sigh of relief.

Then apply ointment on the wound and wrap it with disinfected gauze, and this is the end.
Chapter completed!
