let go of that priestess

But Ji Cheng's goal is not these, but better quality clay.

After a while, Jiang Hongdou found the leaves and came back, and saw that he was still resting on the stone by the river, but his serious appearance did not seem to be resting.

She was a little strange, blinked, came over and put the leaves aside, squatted down, touched him on the shoulder and reminded:

"Here, here, it's all clay."

"Hey, I know, I'm looking for the best."

"the best?"

"Well, let me ask you a question first." Ji Cheng tilted his head and said, "What is the success rate of your tribe's biscuit firing?"

"10 pieces make 3 pieces." Jiang Hongdou thought for a while and said, "Others can be formed, but they are easy to break."

"Ah, the broken ones are not finished. They are still clay, but it is just clay that has been burnt and dehydrated. It has not evolved into a biscuit, so it is naturally brittle."

Ji Cheng nodded and said, "So, do you know how to increase this success rate?"

"Hmm." Jiang Hongdou glanced around and guessed: "You are making it now, looking for better clay? Using better raw materials?"

"The answer is correct~ but it is not standard."

Ji Cheng smiled: "There are two reasons why your success rate is not high, this is only one of them, the other is because of the temperature.

It’s not enough to use a bonfire to burn the temperature. I guess when you fire it, you surround it and fan the wind inside to succeed occasionally, right? "

"Ah!" Jiang Hongdou nodded with bright eyes: "Yes, absolutely right, it's as if you've seen it with your own eyes!"

"Ha, because those are the essential influencing factors." Ji Cheng wrung his fingers and said, "Air-fuel ratio, initial temperature, initial pressure, etc."

"?..."

"I don't understand again, um, I will teach you later."

Ji Cheng pulled back the topic and said: "At present, we have few manpower and tight time, so we can't bet on the low probability that 10 pieces will become 3 pieces, it's better to succeed once, at least, we must try our best to increase the success rate.

Then, it is natural to look for high-quality clay, in fact, it is to look for clay with less impurity content.

Impurities mean that. "

As he spoke, he got up, dug a palm of soil with his hand at a place on the river bank, then moved it casually, handed it to Jiang Hongdou and continued:

"Look carefully, the smallest and most delicate particles are clay, and the larger ones are sand and other gravel."

"Oh, I see."

It was clear at a glance, Jiang Hongdou nodded, but then he was puzzled: "Just sit here and watch, can you identify where the soil is?"

"Yes." Ji Cheng smiled: "Okay, since I told you, let's just explain it thoroughly.

In fact, in general, if we want to obtain clay with less impurities, we need artificial purification.

Purification method [-]: Dry the clay, crush it, and grind it into powder, and then the clay with the smallest particles can be screened out with a sieve. This method takes a lot of time and effort.

Method [-]: Put the clay mixed with impurities into a container, add water twice the volume of the clay, and then crush the clay with your hands without leaving large pieces, and let it stand for several hours to make it fully absorbed moisture, then stir the mass and let it sit for a few more minutes so the mixture will separate into layers.

The bottom layer is silt, the middle layer is a lighter clay mixture, and the top layer is a water layer. In this way, as long as the water layer is pushed away, it will be super fine clay.

So get it?I am now looking for a natural container of nature, and nature will stir us up, a place to sit! "

"Eh......"

Jiang Hongdou was stunned after hearing this, and then looked up to look around.

Danshui River, this river is neither smooth nor fast.

At a place where a river forked, a small puddle of water came into her eyes.

Natural container, stir, let stand.

Isn't that right there!

Under the accumulation of nature over the years, naturally occurring high-purity clay!

Jiang Hongdou's eyes lit up, and he fully understood!

"I see one! Over there!"

"Hey~" Ji Cheng followed her fingers and smiled, then looked away again:

"I've found that a long time ago, um, 1, 2, 3, I've found three places, and I'll start working on two more places."

"I'll help you find it too!"

"Go do your business, say these are my business."

"My business, I have already found the leaves..." Jiang Hongdou picked up the leaves next to it and said, "Look, 5 big leaves, is it enough?"

"Well, that's enough, but finding the leaves is not the end of the job."

Ji Cheng said: "Pull out one leaf for later use, and use your slender little finger to poke densely packed holes in the four leaves.

The charcoal brought is divided into two pieces, one of which is ground and we will wash our teeth later.

The other section is knocked into a block that will not pass through the small holes of the leaves, and then wrapped with 4 leaves layer by layer to form a ball. "

"Okay, remember!"

Jiang Hongdou responded obediently, and immediately started to work, and she still did not forget to study tirelessly: "What are you doing?"

"I was interrupted by the super useful thing you said about salt before. Charcoal is currently useful to us. The third is to filter water."

Ji Cheng explained: "This is a super simple version, a filter device.

We don't have a water boiling container, if we drink raw water to quench our thirst, it will be very troublesome in case of stomach upset.

And this charcoal filter is the best solution I can come up with so far.

But this method is also very bad, and I don't know how effective it is. I just let you do it with the idea that something is better than nothing. "

"..." Ginger red beans were silent, smashed the charcoal, poked holes in the leaves, wrapped them layer by layer, and made a filter.

She meticulously completed what Ji Cheng asked, then looked back at him and said seriously:

"It's not bad, this method, and you who came up with this method, are not bad!

We started with nothing, and now in less than a day, you have solved the fire and food problems, and now you are trying your best to solve the water problem, and you will need to improve the sleeping conditions later.

Of all the men I know, there is no one better than you!

You are amazing, super awesome!I love the science you talk about and love you too! "

"..."

Appeared, white to the girl's classic quotations.

Ji Cheng burst into sweat, how should I answer now...

It would be nice if you didn't add the last sentence...

Food, clothing, housing, and basic survival cannot be completely resolved, so, do you want to consider sex?

Chapter 14 I Have a Bed, But Not Completely

Facing the girl's confession...well, it's a confession, Ji Cheng chose to ignore it in the end.

Just a compliment for her belief in science.

Full of warmth and thinking about sex, full of warmth, I am not satisfied with any of them now.

In extraordinary times, love is the most unreasonable.

There will be all sorts of troubles...

So nothing exciting happened by the river.

The division of labor between men and women is clear——

Jiang Hongdou made a filter device, let the two drink simple filtered water, grind out charcoal powder, and let the two brush their teeth.

Then he cleaned the tattered animal skins brought from the camp, and picked up some flints suitable for making stone axes and knives along the river bank, wrapped them in animal skins, held them in his hands, and prepared to take them back to the camp.

The tasks that Ji Cheng was responsible for were much simpler and more labor-intensive.

Looking for soil, sorting soil, digging soil, moving soil, and finally carrying the clay filled with two big boxes and a shoulder pole, moving slowly, and embarked on the road back to the camp.

On the way, Jiang Hongdou saw him sweating profusely and his muscles trembling, and wanted to help, but the animal skin stone in her hand was too heavy for her, so she had no choice but to spare one hand to help him up. one time.

After struggling to get back to the camp, Ji Cheng let go of the pole, and immediately collapsed on the ground, like a dead dog.

"Hoo... hoo... hoo...

so tired!

Hoo... hoo..."

"I told you earlier, each person carries a frame, you have to carry it alone." Jiang Hongdou squatted beside him, fanning him with her little hands.

Ji Cheng managed to glance at her: "Keep in shape."

"..."

Jiang Hongdou: "Do you care about my appearance so much?"

"I'm talking about maintaining my figure." Ji Cheng: "This is exercising, do you understand. Do you see that my muscles are sharp and angular?"

"Hey, it's not bad." Jiang Hongdou was stunned, and poked the flesh on his back: "It's quite strong, do you have to do a lot of work there?"

"It's not, it's just that as a person who is qualified to drive a time machine, I have physical requirements."

Ji Cheng turned over and lay on his back.

Just lying on the stomach, I can't use any strength on my body, the damn grass skirt is tied up and hurts too much.

It's not comfortable down there at all.

"I have done special training, such as weightlessness and anti-stunning, swimming pool simulation, extreme survival, etc., including training for physical improvement.

It's just that... the physique has improved, and there is no one who does such a heavy job..."

"Oh." Jiang Hongdou nodded, put the things on the ground, leaned over, fanned him with both hands, and she was dripping with sweat.

The beauty is in front, her face is flushed, and her body is drenched.

Ji Cheng looked at her, but at this moment he didn't have the slightest desire, and even felt a little bit disgusted: "Stay away...you are so hot too.

Don't fan, if you still have strength, go to work quickly, we can't rest now, well, I will get up immediately after lying down for a while. "

"Well, I'm going to..."

Jiang Hongdou stayed away obediently, thought for a while and said, "I'm going to dry this rotten animal skin next, and then make clothes for you."

"Hey, wait a minute." Hearing this, Ji Cheng glanced at the sky and said:

"The plan has changed, and we have spent more time than expected. I don't make my clothes, I just make a cover, and I get into it at night. It's the same, and it doesn't matter when it's daytime.

You use more vines, soft branches, etc., with animal skin as the main body, try to make it as big as possible, enough to cover the two of us, this way the cover is solved, save some time, and you can directly make a kang for lying down later. "

"Okay." Jiang Hongdou believed in Ji Cheng's judgment, immediately nodded in agreement, and then reached out to untie Ji Cheng's grass skirt.

?

Seeing her move, Ji Cheng was taken aback for a moment, and subconsciously reached out to stop her, but immediately put it down again.

Forget it......

Didn't she want to do something to herself, understand her pure thoughts——

Of course, there are ready-made vines to use, which can save time, and in the end, they must be returned to cover the body, and it will be fine after taking it off for a while.

Well, that's what I thought...

Ji Cheng is helpless.

Well, anyway, I got used to catching birds before, and now it's so hot that I need to untie it to cool off.

Feeling those little hands groping for a while, the lower body was cold.

Ah ~

Free ~ Stretch ~ Airy ~
