let go of that priestess

"My lord."

Ying Fan waited for Ji Cheng to roughly finish speaking, then scratched his head and said:

"The Damu clan has never built so many buildings before, and you asked us to make an opinion, but we don't know how to raise it?

Just looking at your planning, very beautiful. "

"Indeed, it's neat and tidy." Ying Ying looked at the picture carefully, no matter what area the adults mentioned, the house was drawn in an orderly manner.

What is left in the blank space naturally becomes a road, with an inexplicable sense of beauty and comfort.

Imagine feeling good.

"We may not have any opinions, my lord, just say what to do."

"Uh, are you sure you have no objections?"

Ji Cheng discussed it with Jiang Hongdou when he was drawing the picture before, and she almost had the same attitude at that time.

Considering that it is the first time for the Damu people to settle down, it is reasonable to have no concept of various building facilities.

Ji Cheng was helpless, so he had no choice but to provoke the design leader alone. He spread his hands and said:

"Okay, just three things right now.

First, let the technical manufacturing group 1 dig out the foundation according to the drawings, and the 2nd group learn how to make kilns and burn plain bricks.

Second, the original tasks of the hunting and reclamation team and the gathering team were suspended, and only the basic field care was retained to reduce the hunting time and gathering time.

The poor food is replenished from the breeding group, and now the breeding group has a lot of food production.

From now on, the hunting and reclamation team and the gathering team will go back to dig gypsum and limestone every day to accumulate various building materials.

Third, this is from my side. Next, I will design a waterwheel with Hongdou, borrowing the power of nature! "

Chapter 86 The waterwheel is quite suitable as a civilized gift~

I'm lazy, I want a machine to do my work for me! ——

This is a classic concept in engineering.

Build machines that do the work for you while you're free to do other things.

"If we can learn a way to enjoy the various gifts of the earth without effort, then we can finally stand on top of the world."

Sitting at the table, Ji Cheng spread out a new animal skin, stretched his waist and said.

Jiang Hongdou blinked and sat next to him, propping her arms and head, tilting her head to look at the picture and then at him.

"Waterwheel harnesses the power of nature to serve us

Well, when you said that before, did you know that Ying Ying and Ying Fan looked at you for a moment as if they were looking at God.

This is exactly what God would say, to control nature. "

"Ha, that's just what you imagine God would say. Now that I've said it, what's the matter?"

Ji Cheng smiled, took a charcoal pencil and said: "In simple words, there are so many liquids flowing non-stop on the surface, which is the embodiment of power itself.

All we have to do is make a big wheel and put the sizing on it, and dip the thing in running water, and the water will make it turn.

With the spinning wheel and a few hammers installed, can the plaster and limestone be beaten and ground continuously?

In addition, if it is replaced with other tools, the waterwheel can also grind grain, saw off wood, polish tools, agitate bellows, smelt metal, and so on.

This is, harnessing the power of nature~"

"Your ideas are really amazing."

The reason is not difficult to understand. Just imagine this picture in your mind and you can understand the working principle of the waterwheel, but no one in the Damu tribe has ever thought about it before.

Migrating non-stop, I can't even think about the days for food and clothing.

The benefits of settling down ah.

The benefits of gradually improving facilities

Jiang Hongdou sighed slightly: "Is this the inheritance that has accumulated for endless years, but unfortunately we don't have it here yet.

But having said that, the principle from what you said is simple, but the construction is definitely not easy.

Otherwise, when we built the house, you would have used waterwheels, and you wouldn't have worked so hard to manually crush limestone. "

"Well, yes, it's not easy to make"

Ji Cheng felt a little helpless: "First, if the waterwheel wants to obtain the powerful power of the above functions, it usually needs to be built relatively large or complicated.

So it's absolutely impossible for the two of us to do it.

We can only start designing and manufacturing it now that the village has developed, the food and clothing problem has been partially resolved, and there is hope that manpower can be allocated.

Second, the waterwheel is preferably a metal waterwheel, made of iron.

But without the waterwheel we can’t upgrade the kiln to get iron, without iron we can’t make metal waterwheel, without waterwheel we can’t upgrade the kiln to get iron, without iron we can’t make metal water”

"Stop I see."

The corner of Jiang Hongdou's mouth twitched and said, "Anyway, it's a cycle of infinite contradictions, right? We can only lower our requirements and make it wooden?"

"yes"

"Ok."

Jiang Hongdou shrugged: "Anyway, you will get used to it, so don't be persistent.

Fire kang, hitting stones to make fire, building a house without a foundation, copper gun barrels, etc., are not all adequate. "

"Hey, I know, but there's a little problem this time."

Ji Cheng drew a river at the bottom of the hide:

"Look, the river we're going to use has gentler water, not rushing, and it's not the kind of waterfall that rushes down.

So, how big of a wheel do you think it can push? "

"Eh? Oh!" Jiang Hongdou was stunned for a moment, and then suddenly realized: "To obtain strong power, it must be made larger or more complicated.

This is what you just said, and we can only choose the latter? "

"Yes, to be precise, only smaller water bucket water wheelers can be built."

Ji Cheng thought about it seriously, and began to draw a picture.

While drawing, I don’t know if it’s science popularization or mumbling to myself to straighten out my thoughts:

"The bucket wheel, well, the idea is to put the flow of water under pressure.

The easiest way to do this is to place a pipe vertically with a smaller opening at the bottom than at the top, and let the water flow down the pipe at an angle.

The weight of the water body will accumulate at the bottom, thereby creating a supercharged effect, and then let it hit the wheels like a super-powerful water pipe.

But these 'water pipes' are replaced by wooden ones. Well, I will try my best to make impact blades.

The palms are facing themselves, and the hands are cupped, and the nails are close together.

In this way, the energy absorbed from the running water should be more than 90% if you are lucky.”

""

Jiang Hongdou listened attentively, but still didn't quite understand.

She didn't understand why something that sounded simple in principle before suddenly became complicated.

Combined with the blueprints that Ji Cheng drew slowly, Jiang Hongdou finally understood a little bit.

Before he said that the water flow was too slow, he seemed to find a way to increase the impact of the local water flow.

Recognize the two words marked next to it, is it pressure?

Well, it can be seen that he replaced the flat paddle mentioned earlier with a curved surface with a slightly strange shape.

Well, let's wait until he explains it to himself in detail.

Jiang Hongdou tilted her head and focused on another issue:

"After you draw the blueprint and design it, when do you plan to make water in the village, water bucket water wheeler?"

"Ah, manpower is limited, we have to wait until Ying Fan's hunting and reclamation team and gathering team have dug enough gypsum and limestone to free up their hands, and then let them assist in the production of the technical production team.

A house in a village, plus various facilities we want to build, requires a lot of building materials.

When enough materials have been dug, the Technical Manufacturing Group 1 should also have dug the foundation of the village, just in time. "

Ji Cheng paused, then said with a smile: "Also, at that time, I reckoned that it should be autumn.

Judging from the current situation, no surprises, when the autumn harvest is over, it is the time when we achieve excess production and enter civilization!

I think waterwheels are very good and appropriate as a gift for entering civilization~"

"Everyone work harder!"

Ying Fan and his sister had once again gained full confidence from the adults, and now they are performing tasks with great energy.

Harness the power of nature Hey, adults are really amazing!

My sister said that they should redouble their efforts to try not to hold back the adults, and Ying Fan quite agreed.

Right now, the tasks assigned to them must be completed well.

Mine gypsum, mine limestone!

The place where Ying Fan found the plaster was found by the adults at the bottom of the big pit that was blown up in the rock salt field with divine power.

At that time, he and his team members were digging around at first, but they couldn't dig out. Suddenly, he wondered whether the gypsum would be buried deep in the ground, so he tried it.

The result is really there!

And the gypsum that was dug deep and far down was connected to the place where the adults said limestone.

To be precise, gypsum is inside the limestone.

The adults later told that gypsum is not only often associated with rock salt, but also occurs in limestone, which is normal and they are lucky.

It's really lucky, Ying Fan thought, digging in one place, you can get rock salt, gypsum, and limestone three useful things.

Perhaps adults have thought of this a long time ago!

"Master Village Chief, Lord Village Chief"

The weak and anxious voice of a team member suddenly interrupted Ying Fan's thoughts.

Ying Fan came back to his senses, looked at him and frowned and said, "What's the matter, didn't you just go down the mine a few times and get tired again?

We ate the best meals in the village. Are you not tired from hunting and reclaiming fields?

What's going on today, work harder for me!Don't let the rear support our tribe's jokes! "

"No, Mr. Village Chief, there are some evil ways."

The team member hurriedly pointed to the mine and said, "Several people passed out directly below, we carried them out, look!

This is really wrong, everyone feels tired after going down for a while."

"Eh!?"

Chapter 87 Give me more sulfur

Of course, if Yang Kai deliberately concealed his figure, Monaya thought to himself that there would be no trace of it at such a long distance.

But the battle has been going on for several days, and Yang Kai is still missing, what is he doing?Standing on Monaya's position, the more you can't see Yang Kai, the easier it is to think too much.

At this time, Yang Kai had already returned to Chunyang Pass through the transmission of the Space Law Formation.

Not far away from Mi Jinglun, he hid his figure, and brought together the information he had scouted this time and his own guesses.

After hearing this, Mi Jinglun's expression also became extremely dignified.

According to the information Yang Kai detected, once the elite Mo tribe reinforcements arrive at the battlefield and cooperate with the Mo tribe that does not return to the pass, the human army will be absolutely irresistible. When the Mo people attack, the human race will be in a dilemma.

Fortunately, the support army is far away from here, and it will take at least ten years to get here.
