What?"

When the witch's words fell, faintly, the thief had a feeling that he was about to come into contact with the truth, so panicked that he hurriedly stood up and asked, so that subconsciously, his breathing became tense.

The witch said with an expression that she was not sure about, "Copper." ”

"Copper?" Ji thief, Tushan was stunned at the same time.

Tushan was even more puzzled and asked, "What does it have to do with copper?"

On the contrary, it was a thief, and suddenly there was a clarity in his mind.

After that, the witch continued: "When I asked the people about the situation just now, I found that they were either from the engineering tribe of copper smelting or from the trade tribe of coinage, and there was really nothing in common except for this. ”

As she spoke, the witch sighed, and it seemed that she couldn't find any other reason.

The reason why I say this is just to give Ji Thief an answer.

Who knows, it was this answer that allowed the thief to find the source of the problem.

"Sister Hazel is right, it may be because of copper. Ji Thief pinched his chin and said.

The witch snorted, but she didn't expect that what she said casually really made the thief take it seriously.

"That warrior, I'm talking nonsense, don't believe it, it doesn't matter if you can't find the reason, we can continue to look for it. For a moment, the witch also said in a panic.

Tushan also followed: "Yes, how can it have anything to do with copper, if you want to say so, then the military and military departments and the resources department are in contact with copper mines all day long, is there also a problem." ”

Ji Thief shook his head: "No, you don't understand, Usma's situation is really due to copper." ”

Seeing the confused looks of the two, Ji Thief sighed and said, "Copper is a heavy metal, and if you contact it for a long time without taking any precautions, it will poison copper." Moreover, in retrospect, everyone's symptoms are also similar to heavy metal poisoning, vomiting, diarrhea, dizziness, and brain swelling. ”

"This, this is still poisonous?" Tsuchiyama was stunned.

Like Tsuchiyama, the witch also has an expression of how possible.

Ji Thief said: "Of course it is poisonous, for people, if they consume too much copper, they will die." ”

Tushan had a miserable expression: "It's over, the clansmen have been eating the dishes fried in the copper pot for the past few days, and everyone is going to die." ”

Hearing this, the witch was also full of embarrassment.

Ji thief glanced at Tushan: "Don't talk nonsense, even if it's a copper pot, poisoning can't be done in a few days, the human body has metabolic functions, it's so easy." ”

"So, Patriarch, do you mean we're okay, and we can continue to eat in the copper pot?" asked Tushan.

Ji Thief glanced at Tushan: "If you want to be like Usma, you can continue to eat." ”

Tsuchiyama: "···"

Ji Thief pinched his chin: "It seems that the current situation should be that Usma and some of the engineering tribesmen smelt copper every day and come into contact with the copper element, which leads to heavy metal poisoning." Correspondingly, the same is true for the Ministry of Snow Trade. All of them are poisoning caused by exposure to copper for too long. ”

The witch and Tushan glanced at each other, and they both saw a deep worry in each other's eyes: "Then, how to cure this." ”

Ji Thief thought for a while: "Go to the catering department to find some carbon ash and water for the poisoned clansmen to drink, and then prepare more milk to help nourish the stomach." ”

Tushan was stunned, and asked with some concern, "Is this possible?"

Ji Thief nodded: "Believe me, you know, Xue is also poisoned, and I'm more anxious than you now." ”

Seeing this, the thief said yes, Tushan breathed a sigh of relief and hurriedly went to the catering department.

After he left, the witch was still a little uneasy, and asked Ji Thief, "Patriarch, is it okay if you really do this?"

Ji Thief thought for a while: "I don't dare to guarantee that the medicine will cure the disease, but it is still no problem to solve their current physical condition." As for when it is good, it depends on the individual's ability to recover. ”

"What are we going to do next, warrior? Don't we need copper?" asked the witch.

She knew the importance of copper and the benefits of this thing.

Li Huotong, copper needles, copper spears, copper arrows, etc., are inseparable from copper.

If you give up, then it will be fatal for the development of the Lihuo tribe.

Ji Thief lowered his head and pondered for a long time: "Copper must be used, at least, until I find a better alternative metal." ”

When he said these words, Ji Thief couldn't help but be a little distracted.

Is there a better metal than copper in this primitive society?

In the case of iron, the melting point is too high, and even if you find it, you can't use it.

Those with low melting points, similar to aluminum, tin and the like, are not found.

Not to mention gold and silver minerals, this thing is as rare as the hair on a bald man's head.

The witch looked down at the thief, waiting for the thief's solution.

After thinking about it, Ji Thief said: "It's a big deal to implement the rotation system, and you can't give up the production of copper." ”

"What rotation?" said the witch.

"It's very simple, the military department stationed in the copper mine valley rotates with the military fighting department, and changes shifts every twenty days. The seventy clansmen of the engineering department and the thirty clansmen of the trade department are divided into three parts, which rotate every ten days to minimize the time of contact with copper. In addition, it is necessary to find a way to make a mask to further isolate everyone from contact with copper. Ji Thief said.

The other witches understood, but only one thing, the witches didn't know what the mask was.

So much so that the witch looked at the thief directly, and the thief who watched it was puzzled.

"Why do you think of me like this?" asked the thief, puzzled.

The witch scratched her head, "What is the mask?"

As he opened his mouth to explain to the witch, the thief suddenly realized that there was no such thing as a mask in the primitive era, and there was not even a cloth to make the mask.

There are some materials for making linen, and the kind of flax fiber that is kneaded into a rope is sufficient.

The only thing that was uncomfortable was that there was no loom to make cloth.

The book he gave to Usma had a record of how to make a loom, but the thief had never done it, so he didn't know what to do with it.

Is it impossible to experiment over and over again?

No, even if you try it again and again, you have to get the loom out by yourself, in addition to making the masks you need, more importantly, after making linen, you don't have to run back and forth all day with a hide.

Moreover, you can also make a quilt from linen and wild cotton, and how can you do it without a quilt in winter?

Of course, I won't be able to cover the quilt this winter.

Thinking of this, the thief raised his head and said to the witch: "It's nothing, since the problem has been figured out, if the copper pot is to be used, tell everyone not to use it first." ”

The witch asked the thief, "What about the dozens of copper pots that the engineering department has newly made in the past few days?"

Ji Thief thought for a while and said, "First throw it in the logistics department and put it away, and after a month, when the clansmen are greedy, they will take it out and eat a stir-fried dish." ”

The witch said, "Isn't it going to be poisoned?"

Ji Thief waved his hand: "It's okay, eat it once in a while, the body's metabolic function can completely keep up." ”

Seeing the witch's sluggish appearance, the thief couldn't help but ask her, "What's wrong with you?"

The witch couldn't help but shake her head: "No, it's nothing, it's just that warrior, what is the metabolic function you just said?"

Ji Thief: "···"

After thinking about it for a long time, the thief muttered: "It's just eating and defecating." ”

The witch fell silent instantly.

At this time, Tushan had already run back with carbon ash and asked Ji Thief, "Patriarch, will you feed this thing to everyone now?"

Ji Thief snorted, took the carbon ash from Tushan's hand, turned around and entered the medical department, and asked Ah Qi to bring a lot of crockpots, and then flushed with the ashes and distributed them to everyone, the first one was to feed Usma, who was in the most serious condition.

When he walked to the hospital bed where Usma was lying, he had woken up for more than a day, but his body was still weak, and he was lying on the hospital bed, and there was a female member of the medical department who was expressionless and applied cooling herbs on Usma's body and arm.

Hearing the voice, the female member stood up and looked back, and when she saw that it was a thief, she packed up, hugged the crockpot and went elsewhere.

Seeing this, Tushan not only frowned, but said, "Why didn't that person greet the patriarch when he saw him?"

Ji Thief hugged the water filled with ash and said, "If you don't fight, don't fight, let's not ask for this, it's important to heal." ”

As he spoke, the thief came to Usma's bedside.
