let go of that priestess

Pants......

The corner of Ji Cheng's mouth twitched slightly, and he nodded: "No problem!"

"That's fine." Jiang Hongdou picked up the frame and was about to collect leaves, but just as he lifted his foot, he remembered something.

"Oh, by the way, you said before that our house is going to be built too?"

"Ah yes... after the breeding house is built, we will start to do it.

In fact, our house is already being prepared, but the raw materials and pre-technology have not yet been completed. "

Ji Cheng once again suppressed his resentment of making clothes first and then pants, and seriously answered the girl:

"The place we live in can't be as crude as a breeding house, right? So we need to use better materials to build a more comfortable house."

"Huh? What materials are used to build it?"

"cement!"

Chapter 32 Calcium Carbonate

Spring rain is as expensive as oil, and spring rain is like silk.

With such a statement, Ji Cheng's previous life... Bah!He was familiar with Lanxing before.

I also thank the spring rain for being so rare and gentle. Here, the two people who have been sleeping on the kang in the open air throughout the spring are only occasionally brushed by the spring rain like silk.

But the following summer will be different.

It was a torrential rain accompanied by thunder!

So whether it is from the perspective of sun protection in summer, or to shelter from wind and rain, you must——

Build a house!

After building the white bird's breeding house, the next day.

On this day, the two made meals first.

After eating, Ji Cheng put on the newly woven linen clothes on his upper body and a sexy grass skirt on his lower body, and took the girl to the field together.

"I won't weave today, put the pants back, and do it in spare time, just take your time...

After I'm tending the fields, you go to the river to fiddle and gather the shells you can see everywhere, and then I'll be with you after I finish the farm work.

In fact, I do this by the way every day. Anyway, the river is close to the fields, so I kick a piece of it when I see it.

But now we need to speed up and assign someone to do it.

Those shells are smashed and that's what we make our houses from. "

"Cement?" Jiang Hongdou remembered the word he said yesterday.

Ji Cheng shook his head: "No, the smashed shells are just raw materials. Calcium carbonate has to be fired in a kiln to make quicklime. Quicklime is added with water to turn into slaked lime. Slaked lime is added with clay and river sand, which is the most basic cement.

And the kiln used for firing can't be done with a kang... a new one has to be built.

Usually I ask you to make containers, and the plain bricks I make by the way are used to build kilns. "

"Wow...so that's how it is."

Jiang Hongdou was stunned and said: That's why you said that you have already started to prepare. Well, the raw materials are still more shells, and the pre-stage technology is... to build a kiln.

It sounds like a very complicated thing. What kind of house is it built like this? "

"Anyway, it's not the tent of your clan..."

"Hey, we've built better ones too."

Jiang Hongdou blinked and said, "For example, a house built of pure wood.

Once, the Damu clan stayed in one place for a long time, and the place where the patriarch lived and the house of the priestess were all well built. "

"Oh, that would be nice."

Ji Cheng nodded, and spread his hands again: "It's just that, as you said, the family only supports two such houses.

And there are only two of us, plus a stone axe, with this manpower and material resources, rough processing the logs, and then building a house, that is too tiring.

If you want to further process it into wooden boards...it's even more idiotic.

So just give up building a house with wood, if you really want to imagine the appearance of our future house now, it is almost..."

He paused, pointed to the river that he could already see, and continued:

"Those houses that you make stone tools, less round river stones, and gray mud (cement) are just like this."

"Oh."

Jiang Hongdou imagined it for a while, and then said: "Why use a stone that is inferior to making stone tools? Isn't it better to use harder flint?"

"Huh?" Ji Cheng was taken aback when he heard this, "Flint, that...is hard.

But in the future, we will definitely use ironware such as the hematite we have.

Then, many everyday items including clothes are flammable.

So, do you want to live in a house that can catch fire if you wipe it? "

Ginger Red Bean: "..."

......

......

The plan to build a house officially started.

Useful materials that can be collected by the river: shells (calcium carbonate), clay, river sand, water, and river stones.

The raw materials are directly complete!

So the two discussed for a while, planning to build the kiln near the river and close to the raw materials, so that the subsequent firing can save a lot of trouble.

It's just that after working like this for a few days, they found that the collection of other raw materials was okay.

Only the shells, which seem to be seen everywhere and seem easy to collect, are extremely difficult.

If you want to get enough to build a house, even with Ji Cheng's previous accumulation, the process of picking up small pieces now is really——

too!tired!up!

"Don't do it!"

On this day, Ji Cheng worked again for a while, feeling that his back was sore from bending over to pick up shells, so he went on strike immediately.

He picked up the girl who was still picking up shells, quickly undressed the two of them, and jumped into the river with a plop.

"Eh? You..." Jiang Hongdou was holding a piece of shell in his hand, still in a daze.

Ji Cheng also took this piece of shell, threw it out, curled his lips and said, "Take a break, it's too hard. Come on, put soap on, and let's have fun."

"Well......"

In the cool and comfortable river water, their slippery bodies were pressed together for a kiss.

After a while, their lips parted, and they took a good bath again.

Afterwards, both of them felt happy physically and mentally.

Jiang Hongdou leaned against Ji Cheng's arms with a flushed face, and she also reacted at this moment.

She already knows her husband better, he is not someone who gives up lightly, and even occasionally is irrational...

So when he said quit, he stopped picking up shells, which actually meant that there was another way.

"What are we going to do next?"

"Look for larger natural calcium carbonate, limestone."

Ji Cheng gently kissed the girl's face again, held her and swam to the river bank, brushed away the sand with his hands, and carefully explained while drawing on it with his fingers:

"We already know about rock salt land, remember what I said? The formation of rock salt is the crystallization of salt blocks after seawater evaporates, which is sealed underground, and now it is exposed again.

The calcium carbonate deposited in lakes and seas, after losing water, is compacted and cemented to form rocks, which is limestone.

In other words, if you look at the simple map I drew, with the rock salt field as the center, there should be a whole piece of calcium carbonate rock much larger than the shell around it. "

"Oh!"

Although the map is simple, it is also easy to understand.

Jiang Hongdou understood: "We'll follow these circles later, shall we?

But you usually go into the forest, so you probably haven't seen it?

If you see it, don't look for it. "

"Uh yes." Ji Cheng shrugged: "I didn't find it before, maybe these rocks are still buried in the ground.

So later we'll have to chisel it round and round, hoping it won't be buried too deep and come out obediently.

It stands to reason that this kind of rock is actually quite common, accounting for 4% of the earth's crust in my place.

Here, our luck should not be so bad. "

"Not always......"

Jiang Hongdou glanced at him and warned: "If there is no good harvest, don't allow that..."

"Up."

Ji Cheng said awkwardly: "That's called the boss, don't worry, it won't happen, it's just calcium carbonate, at worst, just take a break and continue picking shells."

"You're wrong!" Jiang Hongdou caught the bug and said, "What is a mere calcium carbonate? If it's food, you can put it on it. If it's on it? That won't work either!"

"I know, I know..." Ji Cheng blinked at her and said, "It feels like you care more and more about me."

"What are you talking about?" Jiang Hongdou said helplessly, "You are my husband."

"Well, by the way, which aspect is more important now?"

"what?"

"The one I mean..." Ji Cheng blushed a little and said, "I'm a man, you have to live by me.

I have science and technology.

Finally, you like me as a person.

Three factors, you care about me now, which one is the more reason? "

"Eh!?"

Jiang Hongdou was taken aback for a moment, then raised her head to stare at Ji Cheng in a daze, her cheeks turned redder for some reason.

"Why are you asking this?..."

"I'm curious."

"However, these three factors cannot be calculated separately at all." Jiang Hongdou moaned like a mosquito, and lowered her head.

"Anyway, I, I don't know..."

Chapter 33

Ji Cheng is very strange.

Ginger Red Bean has known this for a long time.

He has repeatedly stated that he does not like muscular women.

And just now, really, how could I even think of asking that kind of thing...

Which of the three factors is more important?

Ah...she knows, she can guess, Ji Cheng must want her to say: "I like you more."

But when this idea appeared in his mind, Jiang Hongdou felt an unprecedented sense of shyness strangely.

Ming, everyone in the Ming clan, the marriage between men and women is very straightforward, so it's not like this...
