Yu Shu walked in with an umbrella and a piece of paper at this time, and when she walked to the front, she spread out the paper, which was a simple map of Stone Village. "As you can see, this is a simple topographic map of our village, this side is the mountain, our field is here, in the middle is our residential area, and there is some vacant land near the field, so we can dig a pond in this area, and the water flows from west to east, so we should build a pond in these two places, just enough to supply the whole field with water." Yu Shu explained.

Then I opened the second piece of paper for everyone to see, this is a simple drawing of the reservoir, which was drawn by Yu Shu in the shape of a pond, only one gate in each of the four directions of east, west, south and north, and the gate was bolded by Yu Shu.

"This is the special practice of the new pond I want to say, we will make an opening in different directions, usually use a large iron plate to block the main can store water, if you need water in the dry season, you can open this iron plate gate, you can release water." Yu Shu explained.

As for the system of this iron plate with a lifting combination, Yu Shu will personally draw the drawings and find the blacksmith to customize, this matter is not in a hurry, you can dig the pond first.

"So, let's count the number of people who can dig the pond." The village chief said that because it is a matter of the whole village, everyone must participate.

After a period of discussion, each family has at least one laborer, or even more, the village registered its name, and Yu Shu asked everyone if they all have a cloth, if they don't have a clothes, they have to buy a clothes and come back for everyone to use.

In this ancient backwardness, when you go out on a rainy day, you can only use an umbrella or a hat and a robe, and the coat is thick and bulky, and it is inconvenient to wear it on your body to do things.

I only blame myself for forgetting this problem before, otherwise I have to dig the reservoir before the rainy season comes, there is no such trouble, this matter was quickly implemented, and in the afternoon, under the leadership of Yu Shu, we came to the designated place to excavate, some people took hoes, some people took shovels, and some people took dustpans to start moving.

Yu Shu thought about the sketch man who drew a trolley in the house, Pei Qingrin, and asked the blacksmith to make it as soon as possible, and made ten trolleys first, and they drove them at any price.

Pei Qingrin saw that it was something he had never seen before, and couldn't help but take a deep look at Yu Shu, why did the things this little woman give were things that no one in this world recognized?

"It's called a cart, and if the blacksmith thinks it's profitable for them, he can give it to them to make and sell, provided that he helps us get more than ten carts." Yu Shu said.

Pei Qingrin imagined the usefulness of this thing, and immediately set off to Qingshan Town, because on rainy days, Pei Qingrin also walked with a hat and a robe.

Yu Shuzhi sighed how good it would be if there was a raincoat here, but unfortunately his golden finger to the God of Food Treasure Book is not the kind with the function of purchasing items like other crossing scallops, so he can only sigh to himself.

Pei Qinglin braved the rain to come to the town, because the lively streets on rainy days were now deserted, and there were few pedestrians on the road.

Pei Qingrin came to the blacksmith shop and took out the drawings to the blacksmith, but the other party refused, saying that this thing could not be done, it turned out that the trolley painted by Yu Shu was not made of a whole piece of sticker, and there was no welding technology in ancient times, so they didn't know it.

"This man, you're not kidding, I'm a blacksmith, not a carpenter! How do we put our iron pieces together like you draw? The blacksmith said.

At first glance, this drawing is still very innovative, but where can such a large piece of iron be made into such a car? He didn't know how to do it at all, so he could only refuse the other party's customization.

Pei Qingrin had to go through several blacksmith shops in the town with the drawings, and the results were the same, and there was no way to do it.

Pei Qingrin looked at this drawing, if it is wood, it can be nailed together a single piece, if it is iron, how to put it together? Pei Qingrin wondered if Yu Shu was mistaken, and he should let himself go to the woodworking workshop?

What the facts were Pei Qingrin didn't know, he quickly took the drawings to the carpentry workshop, and after getting the carpentry workshop boss to confirm that it could be done, Pei Qingrin selected strong wood and asked the carpenter to hurry up and make it.

"I need more than ten units, please help me make it as soon as possible, I can wait here for a while." Pei Qinglin didn't want to waste time and wanted to go back and forth to time.

In fact, there is a thing called the wooden cow and the horse in the woodworking workshop, which should have the same function as the one Pei Qinglin brought, but the difference is the head and the method of use.

After all, the wooden ox flowing horse can walk as long as the person pushes it from behind, but it seems to be too bulky, this trolley is much simpler, and the owner of the woodworking workshop asked the people below to bring up a wooden ox flowing horse to Pei Qingrin to see.

"We will make what Master Pei needs as soon as possible, but I have a thing here that is the same as yours in terms of function, called Muniu Liuma, you can see if it is suitable and if you need it urgently, you can use this first." The boss said.

Pei Qingrin had seen a wooden ox flowing horse in ancient books, so he was no stranger to this thing at all, and directly watched the worker push out a wooden ox flowing horse.

It was as tall as a real horse, and someone was pushing the wooden ox behind the horse and walking in front of it, as if a real horse were moving.

Pei Qingrin knew from the ancient books that this wooden ox flowing horse was invented by an official of the Ministry of Industry in the previous dynasty, but this thing is only suitable for carrying goods, and it is a small expert who crosses mountains and mountains, and he is not good at transporting soil.

"How do you sell this wooden ox and flowing horse? I'm going to buy one and use it first, and you'll help me make the trolley and I'll take it all back and use it all. Pei Qingrin knew that this thing was not suitable for use now, but in the future, when Yu Shu harvested the crops, he could put the grain into operation.

This thing is mostly ancient books, and there are records of the lackluster that can make real wooden oxen and flowing horses, so it is very expensive, Pei Qinglin spent ten taels of silver to buy one, and paid a deposit for the wheelbarrow, let people carry it to the carriage, and he went to buy a large piece of oilcloth and put it in the carriage and took it home directly.

When she returned home, Yu Shu almost screamed the moment she saw the wooden cow flowing horse, the wooden cow flowing horse! O great wisdom of the ancients!

This thing is well-known to modern people because of the walking wooden ox and flowing horse made by Zhuge Liang in the Romance of the Three Kingdoms, and no matter what kind of technology in modern times, it can't really let the Trojan horse walk on its own.

"Pei Qingrin, I'll let you customize the trolley, what are you going to do when you get me a wooden ox and a flowing horse?" Yu Shu asked strangely, and as soon as she finished speaking, she realized that something was wrong, what is this thing called here, is it also a wooden cow and a flowing horse?
