Ji Chang's big movement finally woke up Chonghou Hu, who was asleep.

Chonghou Hu is still ready to sleep in the shade of the trees today, and occasionally listens to the birds and insects chirping in this countryside, smelling the fragrance of grass and flowers, and sleeps well.

But he found that he couldn't sleep.

I saw a huge thing in the small river beside the shade of the trees, which seemed to be made of wood, in the shape of a dragon, with wooden planks as troughs, and the tail was immersed in the water, connecting the lower river with the higher fields.

Zhang San and Li Si were constantly stepping on the wooden crutches behind the long dragon, driving the wooden chains to turn over and over again, while the scrapers mounted on the wooden chains drew water up, carrying the water all the way to the ditch hastily dug by the edge of the field.

"What is this?"

Chonghou Hu exclaimed.

Ji Chang smiled with satisfaction, stretched out his fingers like the bark of an old pine tree, and said, "This thing is called a waterwheel." ”

"This place is mostly dry land, eight families share water wells, it is inevitable to quarrel, although there is a river nearby, but the terrain is higher, there is no water for irrigation, and this waterwheel, can solve the difficulty of irrigation. ”

"Just place the body obliquely at the water's edge, use three boards to form a rectangular long groove, each end of the groove has a sprocket, the wooden chain passes through the long groove, the lower sprocket and part of the long groove is immersed in the water, the sprocket on the shore is the main wheel, the two ends of the main wheel each have four crutches, the farmer only needs to step on the crutches, drive the sprockets, the scraper draws water along the trough and rises, discharges the water to the trough end, and then returns to the water along the top of the trough, so circulating, the water can be sent to the shore, and extremely labor-saving. ”

Ji Chang gushed endlessly, in this waterwheel, he used a lot of seven-incense car technology, and it was also handy to make it.

As for how to come up with the idea of inventing the waterwheel, it's even simpler, pick up a turtle shell and make a divination, count a few hexagrams, and you can know.

Of course, the price he paid for making such a divine object that benefits the world is not small, but it is worth it.

As soon as the waterwheel came out, the people no longer had the difficulty of irrigation, and even through the bet with Zhang San and Li Si, the world knew in an instant, all this in his hands was equivalent to a life amulet.

Even if he can't let the king relax his vigilance, the king will never dare to kill him Ji Chang at will, as long as the operation is done properly, there will be a day when he will return to Xiqi.

Chonghou Hu pondered for a while, he listened to it for a long time, what scraper wooden chain was flowing downstream, and he didn't understand it.

"This..." He pondered for a while, and for the sake of face, he simply asked Zhang San and Li Si: "Is this thing really useful?"

Zhang San and Li Si struggled to step on the crutches, and said excitedly: "It's useful, it's useful!"

It's useful....

Chonghou Hu looked at Ji Chang, this is another layer of intention of the King of Zhou, the King of Zhou wants to squeeze out the surplus value of Ji Chang.

Ji Chang has been imprisoned for two years, although Xiqi has not made any particularly big moves, but it is also an undercurrent, the war between the big merchants and the princes is irreversible, but the timing is not right, at this time Ji Chang can not be moved lightly, once Ji Chang is moved, it is tantamount to forcibly starting a war with Xiqi.

Maybe someone else will pick up the sweetness when the time comes.

And the King of Xuan has an advantage, which is also the reason why Chonghou Hu believes that the King of Xuan will be a generation of holy monarchs.

Pattern.

The pattern of the king is bigger than anyone else.

What about forging iron tools that are sharper than bronze blades?

The Emperor made the method of forging iron tools public, and even did not prevent the noble merchants from selling the key product of raising the temperature of the forge to other princes.

What about manure, a fetish that increases grain production?

There is no exclusive enjoyment, but in a special way to let the world know, so that every farmer who works hard knows how to fertilize the field.

This time is no exception, although Ji Chang is a sinner, although he is an enemy, he can even be said to be the prince who has the greatest rebellion and the longest plan in the world, but Ji Chang is also the person who knows how to farm the most in the world.

Ji Chang is not only a prince, but also a figure related to the annual harvest of the field.

The king did not depose Ji Chang because of his own selfishness or the hostility of the two families, but used the method of the minister going to the countryside to let Ji Chang do his best.

Can the king not know that Ji Chang will win the hearts of the people because of this?

Can the king not know that once Ji Chang's people's morale rises, Xiqi will be more stable, and even those displaced people who fled from Xiqi to Chaoge may also miss Ji Chang's benevolence in the past?

The king knew it, but he chose to pretend not to know, because compared to those gains and losses, what the king saw was that the people of the world would have a bumper harvest, fill their stomachs, and live a good life because of Ji Chang's invention.

This is the real king who has the world in mind and sets his sights on all the people in the world!

Chonghou Hu sighed a lot for a while, but he was afraid that there would be no such righteous king in the world.

After a long time, he asked Ji Chang: "This thing is like a dragon, it is better to add two words in front of the waterwheel and name it the keel waterwheel." ”

He has to change a name that is easier to spread, and the keel waterwheel is much more imposing and easier to be accepted by the people, so that he can achieve the wish of the king more quickly.

And.... I can also get a little bit of fame from it.

Ji Chang nodded, it's just a name, it's the same name.

Chonghou Hu said: "I don't know how much this keel waterwheel is fake?"

Ji Chang pinched his fingers and calculated: "The materials for production are not expensive, if you count the money spent on hiring craftsmen to make it, the price of a keel waterwheel is not high, and ordinary people can afford it, if you can understand the principle, it is not difficult to build yourself." ”

Chonghou Hu nodded, and then asked, "Lifting the water so high is the limit?"

Ji Chang explained: "The highest drop of the wooden waterwheel is about seven meters, if it is high, the skeleton of the waterwheel can not bear the weight of the water, and it will not save much effort, but if it is made of bronze or iron, it is not too difficult to lift some more, and the cost is higher, but it can irrigate higher land." ”

Chonghou Hu sighed in his heart, it is really something that benefits the world!

With such a divine object, it is no wonder that King Xuan would rather let Ji Chang's reputation rise and pinch his nose to release it.

After all, the heart of the king is all in the people of this world!

Chonghou Hu's eyes narrowed slightly, Ji Chang is not a person who is peaceful, he must cherish this opportunity, I am afraid that it is far from being a mere keel waterwheel that can be ended, but I am afraid that more things can be drummed up.

He slowly walked to the shade of the tree, it seemed that he had to sleep lightly, keep an eye on Ji Chang all the time, squeeze out everything he had, and never let him have any reservations, so as to live up to the intentions of the king.

Ji Chang was stared at by Chonghou Hu, and he also understood that Chonghou Hu was specially sent by the King of Zhou to stare at him.

But he doesn't care, no matter how he stares, no matter how jealous the king is, what he gets is a real reputation!

Now, he began to ponder something else.

Manure has been popularized by the king in a different way, and cultivation does not need to be too scrupulous about the loss of soil labor, and can create a more efficient and faster means to cultivate the land, so as to maximize the advantages of manure.
