Jiangmen Tianjiao: Reborn with funny ancestors

Feng Jia sent someone from Shu to send back a letter and drawings.

Feng Jia said in her letter that she only discovered when she arrived in Shu that the barrel carts here no longer relied on manpower but were driven by water power.

The disadvantage is that the height of water delivery is limited, and water can only be delivered to a place with the same height as the drum truck.

After reading the letter, Chu Qingyan sighed: "The wisdom of the common people cannot be underestimated. I didn't expect that after a few decades, they had already figured out a barrel car that relied on water power."

Feng Jia also said that the barrel cart was huge and it would be difficult to transport a real object back to Ganzhou.

She is convincing two craftsmen who can make bobbin carts to move her family to Ganzhou and will return to Ganzhou later.

Chu Tianjiao got the blueprint of the barrel cart and felt like he had found a treasure.

She immediately summoned the craftsmen from Ganzhou to come and see it together.

In the eyes of an expert, once you have a drawing, you basically have an outline.

Although it is difficult to copy it, it is not impossible to have a clue.

Chu Tianjiao asked one of the old craftsmen to explain the drawings to her.

After listening, she frowned and said: "The bobbin truck is installed on the riverside, taking water directly to the shore and irrigating farmland. This is very useful for low-lying areas!

The center of Shu is a plain, so the water of the Minjiang River can irrigate thousands of hectares of fertile farmland.

But this is not suitable for us in Ganzhou.

Half of Ganzhou's farmland is in mountains and hills, and it is impossible to build such a high barrel truck to transport water.

Let's brainstorm together and think about it carefully. Can we improve how to transport water from the bottom of the mountain to the mountain? "

The carpenters looked at each other, feeling that Mr. Zhou Mu was trying to create a problem for everyone.

Water flows downwards, this is the law of nature.

It is already a feat for the Shu people to use the height of the trolley to fetch water from the river and go ashore to irrigate their farmland.

Master Zhou Mu still wants to let this water go up the mountain. Isn't this whimsical?

After Chu Tianjiao returned from Dongyi, no matter how busy she was with government affairs, she still found time to study the lessons left for her by Taoist Master Xuanqing.

Ever since Li Kuang mentioned that there was an enlightenment book "Yun's Miscellaneous Studies" in Yunzhong Temple, Chu Tianjiao sent people to Yishan to deliver a letter to Taoist Xuanqing and asked Taoist Xuanqing if she could study "Yun's Miscellaneous Studies" .

As a result, Taoist Master Xuanqing not only brought back "Yun's Miscellaneous Studies", but also brought back a book called "Tiangong Kaiwu".

Taoist Master Xuanqing said that this book was silently written by the Patriarch. It is said to be the work of a strange man. It contains a lot of handicrafts and agricultural techniques, which may be useful to Chu Tianjiao.

Chu Tianjiao would read these two books in her spare time. She learned about a power called "momentum". In her understanding, mountain momentum is also a kind of momentum.

This kind of potential can be borrowed. Perhaps this "potential" can make water violate the law of only flowing downwards.

Chu Tianjiao told the craftsmen his thoughts.

He also asked someone to bring a teapot with a spout, fill it with water and show it to the craftsmen.

"Look, I poured water into the pot. Why is the water in the spout the same height as the water in the pot? Can this be used to transport water?

Let's see, if I use a piece of stuff to block this side of the pot and apply pressure, the water on this side of the pot goes down, but the water on the spout rises. Can this be used to transport water?

We can use large moso bamboo to make water pipes and design a structure like a pot and spout.

Can water in water pipes be sent to higher places by relying on hydraulic pressure near the river? "

Chu Tianjiao's words made the craftsmen suddenly enlightened.

The example she gave with a water bottle is easy to understand. Phenomenons like this can be seen everywhere in life, but no one has thought of applying it to water conservancy and irrigation.

After providing the idea, Chu Tianjiao left the matter to the craftsmen to study.

A few days later, Feng Jia brought back the craftsmen from Shu.

When the Shu craftsmen heard Chu Tianjiao's idea, they said excitedly: "In this way, the role of the barrel cart will be greatly improved, and the number of barrel carts used will be greatly reduced."

While the craftsmen were busy studying the problem of hydraulic transportation, Ganzhou gradually began to heat up.

Since the last rain, it has not rained for more than half a month.

Water trucks and canals are under intensive construction, and canals in low-lying areas are gradually beginning to be connected.

There were many more barrel carts along the Dahe and Weihe rivers, and the people were full of curiosity about such behemoths.

"what is that?"

"That's a barrel cart made by Mr. Zhou Mu. It's said to be used to draw water from the river."

"Rain and precipitation are all matters under the control of the Dragon Prince. Lord Zhou Mu extended his hand into the river, will he not anger the Dragon Prince?"

"Nonsense, Mr. Zhou Mu built this cart just because he was afraid of drought."

"What if the Dragon King is angered and no rain is allowed, and a drought really occurs, what use can the little water transported by this truck do?"

"I've heard people say that people in Shu have been using this cart for a long time, and I haven't seen the Dragon King getting angry."

"If you ask me, don't worry about the Dragon Prince. It will rain when it should rain, and it will rain when it should be dry. When we had severe droughts in previous years, we did not anger the Dragon King."

"..."

The people talked a lot. They had never seen such a thing as a barrel cart, and they could talk about anything.

More than half a month passed and it still didn't rain.

At this time, the officials and people in Ganzhou felt something was wrong.

The people began to become anxious. In the fields, old farmers could always be seen squatting on the ridges, sighing at the listless crops due to lack of water.

"If it doesn't rain, the crops will suffer."

"It didn't rain for nearly a month before, but didn't it also rain later?"

"How can it be the same? It's starting to get hot today. Even if we carry water to irrigate the fields, the fields will be dry in two or three days. If it doesn't rain, the crops will really dry up."

"Isn't it true that Mr. Zhou Mu was right and there will be a drought?"

The magistrates of several counties began to feel anxious.

Wu Shiyi, the magistrate of Tianshui County, did not take this matter to heart at all.

"There is the Wei River in Tianshui, so what are you afraid of? Even if there is a drought, those canals dug by Chu Tianjiao can only irrigate low areas, so how effective can they be?

Farming means relying on the sky to eat. If God doesn’t provide food, what does it have to do with me if the untouchables are hungry? "

Several waterwheels have been built along the Dahe River and the Weihe River.

Chu Tianjiao ordered to start collecting water, and the water truck continuously sent water into the built canal.

People in low-lying areas have experienced convenience and their fear of drought has been alleviated.

These people gathered in groups beside the canal, watching the gurgling water passing through their farmland, with smiles on their faces:

"I didn't expect that the ditch built by Mr. Zhou Mu would actually work."

But the people at high places were still panicking.

They began to carry buckets of water up the mountain with their shoulders and hands, and poured them into their fields to alleviate the drought.

After a few days, a craftsman made a piston device that could be opened and closed to pressurize water.

Chu Tianjiao saw that this was a good idea and asked other craftsmen to help improve it. He also sent people to the Qinling Mountains to cut down a large amount of moso bamboo and transport it back.

After countless improvements, the problem of transporting water to high places was finally solved.

There is also a smart craftsman who designed some small mechanisms based on Chu Tianjiao's idea of ​​using the mountains to transport water to distant places. During the transportation, he can use the differences in the mountains to replenish the water pressure so that the water can be transported section by section. .

When the farmland on the first hill was irrigated, the local people regarded this as a miracle.

The Weihe River water is pumped ashore by the water tank truck, then pressurized by the piston device, and transported along the thick moso bamboo pipe to the reservoir on the first hill.

From this reservoir, it impacts down and drives another piston device to pressurize the water pipe next to it and send the water to other places.

……

The common people never thought that one day they would not have to go down the mountain to carry water to the river, but the water would go up the mountain itself to irrigate farmland and provide drinking water for people.

Although water diversion has only been achieved on two hills beside the Wei River, it is already a miracle.

The incident spread quickly in Ganzhou.

After that, Chu Tianjiao called on the people across the state to lay moso bamboo water pipes, build barrel trucks, and deliver water to high places. Not only did the people not complain about the hard work, but they were in high spirits.

With these moso bamboo water pipes, it is much more convenient for them to irrigate their farmland with water not only during drought periods, but also during normal times.

At the same time, Qiao Xing also purchased a large amount of grain from Shu and returned to Ganzhou.

"Miss, because we are harvesting grain aggressively, the price of grain in Shu has increased by [-]%. Do we still need to continue harvesting?"

"Thirty percent is nothing. When the grain merchants in Shu realize that drought has begun in Ganzhou, the price of grain will double."

When Chu Tianjiao asked Qiao Xing to go to Shu to collect grain, there was no drought yet.

The land of Shu is rich. Last year, the land of Shu had a good harvest, and the big families had a lot of grain.

In March, the early rice will be ready for harvest.

Grain merchants in Shu speculated that this year would be a good harvest year, and grain prices would be low.

Therefore, the price of grain purchased by Qiao Xing before was quite cheap.

Chu Tianjiao sent troops, disguised as civilians, and followed Qiao Xing's people to buy grain from various places in Ganzhou.

The granary of the state pastoral office is full.

Chu Tianjiao also ordered a larger granary to be built next to the Ganzhou camp.

But at this time, Chu Qingyan came to Chu Tianjiao: "Jiaojiao, we have no money!"
