For several days in a row, Liu Xiu immersed himself in a sea of books, constantly flipping through the materials about water conservancy in the books. In Liu Xiu's mind, his thoughts were always chaotic and not sorted out clearly.

After reading all the information, Liu Xiujing sat down and sorted out his chaotic thoughts.

It's just a random move, and the effect is certainly not obvious.

You have to have a certain plan, otherwise you can't form a complete plan.

Liu Xiu pondered, comparing the ideas mentioned in the book.

"Digging wells can solve the problem of farmland in a short time. But the biggest problem is that there is too much farmland to ensure that all farmland can solve the drought problem. In addition, in dry weather, even if a well is dug near the farmland, it is not necessarily guaranteed that the well will produce water. Moreover, digging wells requires a lot of manpower and material resources, which is time-consuming and labor-intensive, and the effect is minimal. ”

"The effect of digging the canal is obvious. But if you want to dig a canal, it will definitely consume a lot of manpower, and it will not be completed overnight, and it is not feasible. ”

In Liu Xiu's mind, he kept thinking about solutions.

One by one, they came up with one method after another, but they were denied.

This kind of process is the most uncomfortable, but Liu Xiu must bear it, this is what he must do.

"How can we save material resources and manpower to the greatest extent in the shortest possible time? ”

Liu Xiu thought about it, trying to get his thoughts closer to this aspect.

"There you have it, there is a document. ”

Suddenly, a flash of inspiration flashed in Liu Xiu's mind, and he thought of a possibility.

He hurriedly stood up, hurriedly ran towards Pound's study, entered the study, and quickly rummaged.

"Where?"

"I remember, it was clearly written on the bamboo slips. ”

"The only way to solve the current crisis is to take water from the Han River and then irrigate the farmland. ”

"Rollover irrigation is the best way. ”

Liu Xiu's eyes flickered, and he kept rummaging.

"Find, must find. ”

"This was the first test that the teacher had arranged and it had to be done perfectly. ”

Liu Xiu rummaged through, and his spirit was even more excited.

A roll of bamboo slips was put aside, Liu Xiu looked for it little by little, and he was looking forward to it in his heart.

"It's this volume, I found it, I finally found it!"

Liu Xiu took out a roll of bamboo slips from the bamboo slips, and then quickly spread them out on the desk. He looked at the introduction on the bamboo slip and the graphics drawn on the bamboo slip, and his face showed ecstasy.

He calmed down and carefully studied the structure of the rollover.

Liu Xiu also has a certain understanding of overturning. In the previous life, the irrigation appliance of the overturned car, after Ma Jun's improvement, began to be used extensively, benefiting hundreds of people.

After reading through it, the ecstasy on Liu Xiu's face disappeared, and his complexion gradually became solemn.

"The rollover looks good, but at the moment, the irrigation of the rollover is still not enough, and it is not convenient. If you want to solve the dilemma of Lumen Mountain, you must find a new way. ”

"However, if the rollover can be properly changed, it may work. ”

"yes, why don't I change it?"

Liu Xiu's eyes lit up, and his eyes flashed with brilliance.

At the beginning, when he thought about solving the drought, he was always limited to digging ditches, or digging wells to get water, etc., and the direction of his thinking was to operate directly, without considering the use of irrigation tools.

In fact, digging wells for water, etc., will not work at all.

Otherwise, the villagers near Lumen Mountain would have started the operation a long time ago.

Liu Xiu is different from all people, he has two lifetimes of skills in his mind.

In the first life, Liu Xiu lived in the world of the information explosion, with a lot of information, and his own knowledge was extremely broad, and he knew a lot of things, but he was not proficient in them, but only slightly involved. In the second life, Liu Xiushi was frustrated, and he had to disguise himself, so his mind was withdrawn from the officialdom and all his energy was diverted. As a result, he is quite proficient in both swordsmanship and other aspects.

There are countless predecessors in his brain, but Liu Xiu ignores them and completely deviates from the direction.

Liu Xiu sorted out the bamboo slips scattered on the ground, returned to his room with the bamboo slips that recorded the overturned, and began to think about which one was the most practical after the overturned car was gradually improved.

Soon, Liu Xiu searched for the most common irrigation water wheel in his memory.

Barrel car!

The barrel car is similar to the rollover, but it is more practical than the rollover.

The principle of the cylinder car is to frame the cylinder car in the turbulent river, use the turbulent water flow as the power to make the wheel rotate, and then make the water cylinder mounted on the wheel automatically drain the water, and the water in the river can be lifted ashore for irrigation. The power of the cylinder car is not as strong as the rollover, but it is better to use the endless river as the power, which can rotate infinitely.

To meet the farmland near Lumen Mountain, the tube car is enough to complete.

Liu Xiu's eyes flashed with Dao essence.

He quickly sketched a model of the cart on paper according to the train in his head, and then began to draw it. While drawing, Liu Xiu made notes in the lower right corner of the drawing, and made all the notes on the efficacy of each part.

Liu Xiu's drawing skills are good, and in less than two hours, he drew all the models of the cylinder car.

After doing all this, Liu Xiu stretched his waist and had a smile on his face.

It feels so good to finish!

Liu Xiu put away the drawings on the desk, put away the overturned bamboo slips, left the room, and went straight to Pang Degong.

In the study, the two of them sat down.

Pang Degong's expression was calm and he asked, "How is it, do you have an idea?"

Liu Xiu replied: "Back to the teacher, the disciple has some immature ideas, please ask the teacher for advice." ”

"Tell me about it!" said Pang Degong, waving his hand.

Liu Xiu took out the figure of the cylinder car he had drawn, handed it to Pang Degong's hand, and said in a deep voice: "Teacher, this is the cylinder car designed by the disciple. The principle of the cylinder car is to use the impact of the water flow and then take water from the river. The most important thing is that the drum car can slow down the manpower and material resources, consume not many resources, but can continue to irrigate. ”

After Pang Degong listened, his eyes flashed, and he carefully examined the figure.

The more he looked, the more frightened Pang Degong became.

Not long ago, Pang Degong saw the overturned car made by Huang Yueying. Now seeing the production of the cylinder car, Pang Degong has the most intuitive concept when compared with the two.

This design can be called a classic, far better than a rollover.

After Pang Degong read it carefully, the shock in his heart was indescribable.

In my heart, there is a kind of happiness.

I'm glad I accepted Liu Xiu as an apprentice!

Pang Degong took the drawings in his hand and immediately wanted to go down the mountain to find Huang Yueying.

Suddenly, Pang Degong's mind changed and he ordered: "Xiu'er, if the structure on the drawings can really be completed, the crisis of water shortage in the farmland around Lumen Mountain can be easily resolved, and you have done a very good job." ”

Liu Xiudao: "It's all the teachers who teach well!"

Pang Degong smiled and said, "I'm just asking you to figure out a way, how can you teach?" Okay, don't be modest. You take the drawings and go down the mountain immediately, and go to Huang Chengyan's house at the bottom of the mountain to find Huang Yueying. She is very good at the art of traps and can help you. ”

"Yes!"

After Liu Xiu heard this, he turned around and withdrew.

Soon after Liu Xiu left the study, Pang Fu came to Pang Degong's study and reported: "Master, there have been a few people of unknown origin who have come to the mountain recently. ”

Pang Degong said in a deep voice: "What is the origin of the other party?"

Pang Fu said: "It's the people of the Cai family, who keep inquiring about what Gongzi Xiu is doing." The rest, however, were not found. ”

Pang Degong's eyes narrowed slightly, thinking carefully.

After a long time, Pang De said fairly: "You sent someone to deliver the news, and it was said that Xiu'er had found a way to alleviate the drought." Currently, this plan is underway. ”

"No!"

Pomford received the order, turned around and retreated
