I was a village chief in a primitive society

Chapter 259: A novel aid package. (3 more please customize)

At noon, Su Bai signed in silently in his heart and opened the aid package, and got a fifty-five-degree cup.

When I got up in the morning, because the fox-eared girl was always there, I forgot to sign in.

He looked at the pure black cup in his hand and was stunned for a moment. He didn't expect there to be such a cup.

"But it’s still a good thing in summer."Su Bai opened the cup and poured some hot water into it.

After screwing on the lid, he started to shake it. After a few minutes, he stopped shaking.

Su Bai opened the lid and took a sip. He raised his eyebrows slightly and said:" Not bad, it did become warm water."

The 55-degree cup is a new product on the other side of the earth. Pour boiling water in and shake it, and you can get a cup of 55-degree water, which is considered a novelty. The main working principle is to store it in a food-grade stainless steel interlayer A micron-level heat transfer material has been developed.

These materials will undergo reversible solid-liquid conversion at the micron level as the temperature changes.

When the temperature of the water poured in is higher than 55°C, the heat can be quickly conducted to the cup wall and stored..Thus, the water temperature drops to about 55℃. When the water temperature is lower than 55℃, the material will slowly release heat.

Since the heat transfer material is a pure physical phase change environmentally friendly material, it has fast heat conduction speed and high heat storage efficiency.

"The system was actually able to drive this thing. It was the first time I saw the real thing."Su Bai muttered to himself.

But this kind of thing is not a high-tech product, and the cost is not high at all.

The lining of the cup wrapped in the outer packaging is some sodium acetate trihydrate, 92% of this substance As a heat storage agent.

There are also 5% sodium hydrogen phosphate dodecahydrate as a nucleating agent and 3% gelatin as a thickener. The phase change temperature is about exactly 55 degrees.

This is a so-called high-tech product. In fact, it is a large type of melt. The phase change temperature of salt is between 50 degrees and 60 degrees, but this 55-degree ratio is the cheapest, and the others are just one cup!

For example, the main principle of the baby warmer we use is three hydrates The crystallization of sodium acetate releases heat.

The market price of this kind of warm baby is one yuan a piece. It can be imagined that all the materials add up to only five yuan.

So the so-called fifty-five-degree cup is just more expensive than an ordinary cup. Just a few extra dollars

"Just treat it as a novelty."Su Bai smiled slightly. It's better to have something than nothing at this time.

And in the summer, when you suddenly want to drink water but only boiled water is available, this thing can still come in handy, although there are not many opportunities to use it.

"yawn....."

Su Bai let out a long yawn and murmured to himself:"I'll have to catch up on some sleep in the afternoon."

He experimented with healing techniques again last night and didn't go to bed until midnight. The experiment he performed was to crush the hare's legs. Drop it and see if you can put it back.

At first, Su Bai chopped the hare's leg into pieces and couldn't recover it when he used the healing technique.

The second time it started not to be so broken, and then the recovery effect of the healing spell was not very satisfactory.

So the third and fourth time.....It took more than a dozen experiments to arrive at a theory.

That is, if you break an arm or a leg, if the broken leg is bitten to pieces by a ferocious beast, there is no way to recover it.

The only thing that can be restored is a broken leg. The degree of fragmentation can only be restored to about three pieces.

"Last night's experiment was considered useful. After reaching the third level of the healing technique, you should be able to reattach the thin legs, right?"Su Bai murmured to himself.

Sha Lan stepped into the wooden house and asked:"Witch, I have finished training, is there anything you want me to do?"

"You can help me recruit a group of people. I need more people to sew linen, make paper and make porcelain."Su Bai ordered.

He was also thinking last night. There are not many people making linen, porcelain, and Wolf's tail paper now.

Moreover, they have moved back to their ancestral land and started building cement houses. What about these three major industries? It's time to increase the number of people

"Yes, I wonder if Wu has a suitable candidate? I can tell them directly. Sha Lan asked

"I am not familiar with the people in the tribe. You know better than me who I can trust and who is suitable for what job."Su Bai said.

Sha Lan fiddled with her long blue hair, and her cat ears twitched. This feeling of trust was really good.

She nodded heavily and responded:"I know, I can do this. Done for the witch"

"Let me make some requests. The people you recruit should be from our Yanlong Tribe. We don’t want those from the Black Snake Tribe for the time being. Su

Bai thought for a moment and added:"All linen makers are girls. They need to be smart, have a tight mouth, and they need to be dexterous.""

"Okay, is there anything else?"Sha Lan kept silently remembering it in her heart.

"Those who make porcelain need to be a little older, but not too old. They should be in their forties. They should be mainly men. For the time being, four or five people will be fine. It doesn’t take too many. You need to find some with experience in craftsmanship. Su

Bai rolled his black eyes and continued:"There are no big requirements for making Wolf Tail Papyrus. Both men and women can do it, but the premise is that it must be kept secret, otherwise it will not be as simple as being kicked out of the tribe.""

It was the first time that Sha Lan saw Wu being so serious. He nodded without hesitation and said,"I have remembered it all and will definitely follow Wu's request.""

"Tell them that as long as they keep the secret well, they will have extra dried meat to eat every day, and they will also be given linen cloth when the time comes."Su Bai added

"Wu, actually there is no need to say this, they will keep it a secret, because they are all from the Yanlong tribe."Sha Lan thinks this is a bit of a waste of dried meat.

"It doesn't matter, just do as I say, don't worry about not having enough dried meat, you will definitely have enough before the rainy season comes."Su Bai said with a smile.

Of course he knew what Mao Er Niang was worried about. It was just that the tribe did not have enough food. Now he is giving the extra to these people, which is a bit superfluous.

"I see. Sha Lan nodded and turned around to leave the wooden house.

Yu Ying blinked her pink eyes and asked doubtfully:"Wu, why do you need to add more dried meat to them and distribute linen cloth to them?""

"Only in this way will their motivation to work be greatly improved, and won't we get more linen, porcelain, and Wolf's tail paper?"Su Bai asked back.

"It turned out to be like this, but they were willing to work even if we didn’t give them more."Yu Ying said softly and cutely.

Su Bai scratched the tip of the fox-eared girl's nose and asked with a smile:"Then I say you have finished sewing a linen garment today, and I will give you a large piece of meat. Are you willing?"

Yu Ying nodded without hesitation, her round little face was very cute,"I am willing."

"That’s it, you can’t sew one piece in one day, right? That big chunk of meat is motivation."Su Bai explained

"I see."Yu Ying narrowed her eyes and smiled..........................................
