The county magistrate's daughter only wants to farm

After drawing the structure of the pulley and tripod, Gu Yin looked up at the two of them and said, "Do you understand what I'm saying?"

Niu Dachui nodded: "Isn't the axle of this pulley similar to the roller of the thresher?"

"Yes, the principle is the same, but the outer wheels are one with gears and the other with smooth grooves."

The old tree seemed to be thinking: "If we put more pulleys together, can we save more effort?"

Gu Yin was stunned when he heard this. He was indeed a master at mechanical engineering. He discovered the wonder of the pulley system so quickly.

He smiled and praised: "Brother Gu Shu, your brain is really quick. You even figured this out. However, although the movable pulley saves effort, it does not save distance, which means that the required line will be longer. You can combine them according to the actual situation. The most suitable one is the best."

The old tree smiled innocently: "The county lady said before that moving the pulley can save effort, so I just made a guess."

"Hehehe... young people are still smart. You see, I didn't think of this." Niu Dachui patted Gu Shu's shoulder and praised happily.

Niu Dachui didn't see that when he slapped Gu Shu, his face almost wrinkled into a bitter gourd. But there was a smile in his eyes.

Afterwards, Gu Yin explained to them the pulley system composed of multiple pulleys and how to wind the wire in the most labor-saving way. Finally, he made a summary: "I called you all here because Brother Gu Shu is good at making mechanisms and Uncle Niu is very skilled in blacksmithing. I hope that the two of you can work together to make the pulley as soon as possible."

After listening to Gu Yin's explanation, the two nodded solemnly.

The fact that the county lady took out such important tool drawings showed that she trusted them. So, how could they let her down?

Moreover, since they already have the blueprints, it is not difficult to make the finished product. This is a good opportunity for them to make a contribution.

"Keep working hard, there will be rewards if you do well!" After explaining the matter, Gu Yin did not forget to make a promise, which of course can be fulfilled.

"Thank you, Princess!" They both thanked her in unison, their voices rising several degrees.

An excited look appeared on Niu Dachui's dark face.

Even if there is no reward, they will work hard, but who wouldn’t be happy if there is a reward?

Only fools can't get along with money.

After discussing the pulley, Gu Shu thought of what Gu Yin had said before about the two tools and asked:

"The county lord said before that there were two tools, the first one was a pulley, so what about the second one? What is it?"

"trolley!"

"trolley?"

"Yes, it's a cart!" Gu Yin nodded affirmatively.

He saw that the workers were still carrying the soil manually, which was not only laborious and tiring, but also inefficient.

When Gu Yin thought of the pulley, his mind suddenly seemed to be cleared and he immediately thought of the cart.

The Daji Dynasty had horse-drawn carriages, which meant that wheels were not a problem. By putting a few wooden boards on the wheels to secure them, they could be used as wooden carts, which was perfect for transporting sacks.

By replacing the wooden boards with wooden boxes, they can be used directly to hold the soil. A large truckload can be moved at a time. Isn't it faster and more labor-saving than carrying it on a shoulder pole?

As Gu Yin spoke, she drew a picture of a cart. Although it was simple, it was clear enough to understand.

“This should be easy to do.”

"This is not difficult. It's just the carriage without the upper compartment." Gu Shu understood it immediately.

"That's right. If you modify the wheelbarrow, you can also make it into a bucket cart. That is, replace the wooden board on top with a bucket-shaped wooden box, like this." Gu Yin said, and drew the original straight line into an arc that was shallow at the front and like a big belly at the back.

"Great! After this modification, it can be used directly to store soil, and it will be much more convenient to pour it." Niu Dachui understood, clapped his hands excitedly, and shouted in a loud voice.

After getting the structural drawings of the two tools, the two did not dare to delay and immediately got up and prepared to go back to work.

"County Princess, let's go back and think about it now and make sure we can get it done as quickly as possible." Niu Dachui patted his chest and promised loudly.

The ancient tree standing aside also had a determined look on its face.

"Okay, then I'll leave it to Uncle Niu and Brother Gushu. Try to delegate other tasks to others, and focus on researching new tools. If you can come up with a tool that can significantly improve work efficiency, you will not only be generously rewarded, but you will also get a certain share of the profits after the new tool is sold."

The two of them nodded repeatedly after hearing this. Working for the county government not only earned them a monthly salary, but also received rewards from time to time. They had never dared to dream of such a job before.

With the help of pulleys and bucket carts, the construction speed of the county sewer was as fast as riding a rocket, soaring up.

Seeing that the sewer on the main road was about to be repaired, Gu Yin began to arrange another thing, which was to persuade the surrounding residents and shops to dredge their own sewers and discharge domestic sewage and daily excrement out of the city through the sewer of the county town.

When designing the county's sewer system, it was actually divided into two channels.

One is used to dredge rainwater and domestic sewage, which can be discharged directly into the Lingshui River outside the city.

Another one is used to drain excrement, which is collected in several huge septic tanks outside the city. This is a good fertilizer that can be used to irrigate crops.

It’s just that… the idea is good, but the actual implementation doesn’t look that good.

"Get lost! What are you digging for? Our house is fine, why are you digging a hole underneath?"

"No... Auntie, if we dig a passage to connect the toilet to the outside, you won't have to work so hard to empty the toilet at night. It will be much more convenient in the future." The yamen runner who was sent to persuade the people to dig a sewer patiently persuaded the lady in front of him.

"Why is it so hard? Where is it hard? Don't you want to send someone to collect the night incense in the morning?" The old lady insisted.

"That's not what I mean. If the sewers are unblocked, all domestic sewage can be directly discharged outside the city. We won't have to smell those bad odors anymore. Wouldn't our living environment be better?"

The county government has always sent people to collect the night incense from every household in the morning. There is no other way. If no one is sent to collect it, some families will just throw their feces on the street.

When wealthy people heard about the function of sewers, they all expressed their willingness to cooperate. This is a mutually beneficial thing.

If the feces can be directly drained out of the city, wouldn't their houses be much cleaner? It's worth digging the sewer.

However, Gu Yin didn't want to bother with families like the old lady. He sent people to inform each household now, just to make the subsequent supervision smoother.

Everything is easy for those who listen to advice, but for those who are unreasonable, it will just be a matter of their father's orders.

In extraordinary circumstances, Gu Yin does not reject the use of some coercive measures.
