(Thank you for the reward of the overbearing sword emperor who picks the wrong one when he is in a bad mood!) Thank you! ）

"Fifth brother, is this salt okay? Just found from a bandit. ”

Duvowe handed over a small cloth bag containing a handful of blackened coarse salt.

The salt is coarse and the particles are large.

Especially yellowish, some are black, such salt used to be pickled cabbage, and I couldn't look down on it. But Luo Cheng knew that most people actually ate such salt at this time.

It's just like that, it's still expensive, as the saying goes, a bucket of rice can only buy a pound of salt.

Although the quality is a little different, it is at least much stronger than Lao Jia's sour salt and vinegar cloth.

"Find an iron helmet, fetch some water, and boil a new pot of water."

Luo Cheng began to command.

"Fu San, you get some wood to make a fire, not to boil water, but to burn some charcoal. Will you burn charcoal? ”

"Yes, fifth brother, I can burn charcoal, I used to burn charcoal with my father, but I was too tired to make money."

Luo Cheng stopped his memories, "It's good to burn charcoal, I don't want much charcoal, you can simply build a fire, and then make some charcoal for me." ”

"Third brother-in-law, you go over there to find the captives and take a look at the ones with clean clothes on your body and pick up one or two pieces."

Qin Qiong asked a little puzzled, "What is this for?" ”

Lao Jia was eating his piece of vinegar and salt cloth to cook meat, "What is delicious, you have to boil water and charcoal and pick up clothes?" Do you really want to try grilled human flesh? ”

Luo Cheng pointed to the injuries on everyone's bodies.

"Help everyone take care of their wounds."

"Dealing with wounds? Is it like that? Isn't it just a matter of getting some grass and gray soil to stop the bleeding? ”

"Of course not, if you fool around like this, it is easy for evil qi to enter the body, and then get fever, and in the end, if you don't get it right, you will talk nonsense, fall into a coma, and even fester. Don't look at the small wound, sometimes a small incision can make you amputate a hand. ”

Lao Jia suddenly fell silent.

It's just that his eyes when he looked at Luo Cheng were terrifying.

"Boy, what you said is true, you can boil some water to prevent these evil qi from entering your body?"

"Of course, I don't dare to say that I am 10% sure of it, but at least it can be reduced by 50% or 60%." Luo Cheng did not brag, wound infection is a terrible thing, it is said that during World War I, a large number of soldiers died not directly in battle, but died of infection after being wounded.

In the ancient cold weapon war, it is said that less than 10% of the soldiers killed died directly in the battle, and more died from wound infection.

Especially in the era of cold weapons, any wound is often easy to cause irreparable consequences, after all, at this time, there is a lack of medical treatment, sanitary conditions and health concepts are backward, and everyone does not know how to protect.

"Xiao Wu, what do you say, just say it, I'll give you a hand." Lao Jia almost gritted his teeth and said.

Luo Cheng looked at him with some surprise, and then saw his one-armed.

"That's right, when I was in the southwest with the county to suppress the rebels, I was hit by an arrow in the arm, I thought it was nothing serious, but then it was red and swollen, and then it became more and more severe, and it was pus. In the end, although I went out of the mountains and found the doctor in the camp for treatment, it was too late, and I had to cut off my entire arm. ”

"If the method you said is really effective, then I don't know how much it will help my Wei Mansion soldiers!"

Luo Chengdao, "The conditions here are very simple, in fact, there is not much that can be done, so you can only do some simple cleaning and bandaging first." ”

"You don't have to tell me so clearly, you help Shubao do it first, I want to see the effect." His face was swollen and red, and if someone had been able to help him with his wounds, maybe he wouldn't have hung an arm forever.

The water boiled, and Luo Cheng threw the black coarse salt into it to boil.

"What do you do with boiling salt to clean wounds?"

"Salt water can remove evil and disinfect!" Luo Cheng explained simply.

There are too many coarse salt impurities, so Luo Cheng can only purify it by himself first.

Boiled the salt.

Then wrap the charcoal powder that has been ground into powder and make a charcoal bag to filter the brine. After filtering several times, some obvious impurities are adsorbed away, and finally boiled again until the salt crystallizes after boiling.

A group of people gathered around Luo Cheng, and they all stared at Luo Cheng's complicated operation with wide eyes.

When the water in the pot was boiled dry, and a small pool of white salt powder appeared, their faces were swollen and red.

"Salt, salt like snow!"

"Oh my God, salt can do this?"

Lao Jia couldn't help but press his finger into the salt powder, dip it and stuff it into his mouth.

"This salt is not bitter!"

"How can there be salt that is not bitter!" The fourth child shouted, and also got some taste.

As a result, when I tasted it, my eyes were about to pop out, "It's really not bitter, it seems to be a little sweet." ”

Luo Cheng glanced at him, this salt actually seemed to him to have a lot of impurities, after all, this filtration method was too simple, the salt was not so black, but it was still a little yellowish, and it was still relatively coarse.

But in Luo Si's opinion, this salt is simply a big trick.

"Such snow-white salt, at least several times the price to buy." After all, he has seen a lot of the world, and no matter how good the green salt is, the whiter and finer the salt, the more expensive it is, and he knows this truth better.

Luo Si's eyes lit up, the bag of salt just now became a lot less after it was boiled, but it was not several times less, and this salt was actually worth several times more when it was boiled and filtered, so didn't it mean that as long as you bought some black coarse salt to filter, you could make several times more money?

It's a cornucopia.

"Lao Jia, this method is the family secret of our Lao Luo family, you can't say it when you see it, and you are not allowed to steal it to make money!"

Lao Jia snorted, "Is Lao Tzu that kind of person?" I'm more concerned about how this salt water is disinfected! ”

"Dissolve the salt again in hot water, and then wait for the water to cool before wiping the wound to remove the dirt from the wound."

Luo Cheng asked Qin Qiong to take off the clothes on his body, revealing his bronzed muscles, and after a night of fighting, there were seven or eight wounds on his body.

Fortunately, most of them were skin injuries, not too serious.

However, it was not bandaged in time, and although the bleeding at the wound had stopped, the blood scab was blurred.

The water in the other iron helmet was also boiled, Luo Cheng threw a piece of cut white linen cloth into it to boil, washed his hands with water, and then took out a dagger, washed it and roasted it on the fire.

"What are you doing here?"

"Wash the water to prevent the wound from being contaminated by the poison on your hands. The same goes for the cloth and the knife, it should be cleaned and disinfected! ”

Everything was ready, Luo Cheng first took the boiled linen cloth to clean Qin Qiong's wounds, and after washing it, he rinsed it with salt water a few more times.

In the process, Qin Qiong clenched her teeth and didn't say a word.

"Second brother, there are a few wounds that are relatively large, and some rotten skin and flesh need to be cut off, and some need to be stitched up with needles, so that they can get better faster, do you believe me?"

Qin Qiong took a look at the few cleanly washed wounds, "My brother, if you don't believe it, you can come!" ”

"What? Do you still want to sew it up with a needle? Needle-sewn skin and flesh sewn clothes the same? You're not kidding, are you? Lao Jia asked in surprise.

"I'm not kidding, after suturing the wound, it helps to speed up the recovery, and it can also prevent the wound from being exposed, so as to prevent the wind evil virus from taking the opportunity to invade."

"But I always thought you were joking." Lao Jia swallowed.

"Are you kidding, you'll know by looking at the effect in the end!"
