What is more advanced than the lever is the wheel shaft principle, which is mostly used to collect water from wells. In later generations, people who have wells at home and in the village have seen them, which are quite labor-saving.

Similar to the winch, there is also a kind of mechanical winch "wind" that is equivalent to a modern winch powered by human or animal power. The shaft of the winch is placed upright and is mostly used for traction of ships over weirs.

On the water shore of the Gu family, you can still see crane drinks standing. Sometimes, households use it to get water, so even if there is a crane drink, it is still there.

The overturning is larger than the previous tools. If the water flows rapidly, you can use hydraulic power to rotate, but if the terrain is flat, you will have to trample on it.

Its overall structure is made of wooden boards into a long groove. Dozens of wipers commensurate with the width of the wooden groove are placed in the groove. The wipers are connected in sequence by hinge and connected to the ends. There are toothed wooden shafts at the upper and lower ends of the wooden groove. When the upper and lower ends of the wooden groove are rotated, the wiper will be carried up to pour into the canal.

Looking through the League of Legends, the Crow, the Snake is sure to be the Snake.

Once this thing is running, it is still very powerful to irrigate the land.

The only drawback is that Gu Qingyi didn't have enough money at that time. Most of the keel rollovers were renovations, but she couldn't ask for more financial resources. Now she is very satisfied if she can use it.

Li Mingying listened to Gu Qingyi explaining these to her. Although she had read some books and heard others mention them occasionally, she could learn that she had put in a lot of effort like Gu Qingyi, and knew very well.

There is a keel overturning carriage along the river bank at any distance, taking the river water up and sending it into the ditches, and the river water flows into the fields along the ditches.

There are at least a dozen of them wherever they see them. The green seedlings in the field are waving in the wind. The vitality is really touching in this chaotic world.

"How could Sister Qingyi think of making these things? Which ordinary girls know about this?" Li Mingying asked sincerely.

Just like her, she never thought she would come into contact with these things in her life.

But now standing here, looking at this green land with vitality, these seedlings will bear fruit and be put into the granaries. Then this is the hope of survival.

For some reason, her heart seemed to have also swayed with the seedlings that were dancing in the wind.

Gu Qingyi felt miserable inside, and she was forced to go to Liangshan, or it might be too difficult.

But this is definitely not something that way. She looked at Li Mingying and smiled generously, saying, "Sister Mingying, at first I came here just to live well, but later I saw that the refugees had no place to settle down, but I couldn't afford them, so I could only let them open up the land and raise themselves. If the land was opened, you had to plant it. If you want to have a harvest, you had to fertilize and water it..."

Listening to Gu Qingyi's last helpless sigh, Li Mingying was amused and looked at her with a gentle expression, "You are very kind in your heart, willing to endure hardships, and with a little intelligence, you have just had this prosperous scene in the Yuzhou. Sister Qingyi, I have read so many books and feel ashamed that I am far from you."

Not as pragmatic as you, not as kind as you, not as eagerly expecting this troubled times, and tolerating refugees from all over the world.

The future may be difficult, but every step you take is bright.

Li Mingying's thoughts were surging. She knew that there were so many girls in the world, but only Gu Qingyi dared to do this, which was inseparable from the support and trust of the Gu family.

The recognition and yearning for the Gu family quietly took root at this moment.

Li Mingying is looking forward to this marriage first.

However, it is still unknown whether the Gu family can fall in love with her daughter-in-law. Maybe she still has to continue working hard to achieve it.

Li Chaying was also very interested in these things. Listening to her cousin talking with her friends, she carefully observed it before speaking: "It's very expensive to build a piece of this thing, but you have made so many, no wonder you always cry poorly."

Gu Qingyi:...

"This is a refurbished, how can I make it a brand new one?" Gu Qingyi smiled helplessly, "Refurbishing saves money, but it is not durable. You can make up for it first to repair it. This is also impossible."

The more Li Mingying looked at him, the more he liked Gu Qingyi. Which girl could openly promote the issue of poverty? Everyone kept talking about yellow and white things, but their words and deeds had to declare how extravagant food and clothing they were.

Looking at what Gu Qingyi wore, what he wore, and what he used, and looking at the changes in Huzhou, Li Mingying felt indescribable.

It seemed that at this moment, something in her heart was knocked over, but she couldn't get what she wanted for a while.

He wandered, yearned, and hesitated. Many thoughts surrounded her heart.

"I see that these seedlings are stronger than other places." Li Mingying squatted down and looked carefully.

When they came, they saw fields on the road, with short and yellow seedlings, which were not as beautiful as Huzhou.

Gu Qingyi smiled and said, "Grain seeds should also be selected and cultivated. Full seeds always grow better than shriveled ones."

Li Chaying nodded, "It makes sense, but it would be too troublesome if so many seeds from the fields had to do this."

For the gentry, thousands of acres of land, selecting grain plants is also a hard and time-consuming task.

Gu Qingyi spread his hands, "There is no way. If you want to collect more food, you have to put in more effort."

Li Mingying looked at the green seedlings thoughtfully. Yes, the grain seedlings that had been exhausted are naturally much better than those who left their fate.

Li Mingying really likes chatting with Gu Qingyi. Not only does it increase her experience, but the key is to let her see the scenery she has never seen before, things she has never heard, and know a lot of knowledge she should know.

After returning, Li Chaying felt that her cousin was a little weird, so she sent the maid out and said softly: "Sister, what's wrong with you? Why am I a little unhappy when I look at you?"

Lee Mingying looked up at her cousin, "I finally understand why you are good friends with Qingyi."

Li Chaying said proudly: "Cousin, am I right? Qingqing is really a very comfortable friend. You will be very happy to be with her. In fact, you didn't do anything special, but you just feel relaxed."

Lee Mingying nodded. Cha Ying was different from her. Cha Ying grew up with her uncle and aunt in Hye Kang, and the environment was not as complicated as hers. So Cha Ying herself is relatively purer than hers and is easy to be happy.

She is different. She has grown up in the clan since she was a child. She has a huge family and a few hundred relatives. She has learned to observe words and expressions since she was a child, knowing how to give herself an advantage among sisters and brothers, how to make the clan leader value it, increase her weight and thus make her mother's status more stable.

She was very thoughtful, cautious at every step, thoughtfully, and thought about things over and over again, but she was not sure and never did anything that was disgusting.

Therefore, not only is her identity as the eldest daughter in the clan, but the most important thing is that she has the most proud thing about the Li family, that is, as a girl, she has become a benchmark for her life.

Stand out and compare with the lady from the side, oh, the girl from the Li family is really excellent. This is her capital and the skill she relies on for survival.

But she now finds that she is wrong.

Gu Qingyi let her see that a woman could live in another way, a look she had never thought about.

"You're right." Lee Ming-ying said, it's indeed a very amazing skill to make others relaxed.

Some people do things throughout their lives and others make people feel disgusting.

Girl Gu is the last one.

"Sister, are you okay?" Li Chaying sensitively found that her cousin's mood seemed to be a little wrong.

Lee Mingying looked at her sister helplessly, "I just envy Qingyi."

Li Chaying almost rolled her eyes when she heard this, "Who doesn't envy her? I'm also envious! I haven't seen any girl from a family who can do whatever she wants. Sister, you haven't seen her. When she was in Huikang, the uncle and aunt of the Gu family were very spoiled for her, and she didn't spoil her. Can ordinary people control her? Anyway, Qingyi is not an ordinary person."

If she weren't a female playboy!

Li Mingying smiled and didn't say anything else. Her cousin was also very smart. If she asked too much, she would inevitably become suspicious. This is a good thing.

The Li sisters talked to Gu Qingyi at night and didn't know that she was talking to Zheng Huan now.

Zheng Huan came to find Gu Qingyi specifically because he sat opposite Xi Changnian all night and still couldn't figure out some parts.

Girl Gu is cunning and intelligent, and she might have any inspiration when chatting with her.

Gu Qingyi had a headache when she saw Zheng Huan, but she had to pretend to be nothing and listen to his nagging matters. As she listened, she looked serious.

"The result of the encounter between the two divine objects of nitrogen, the ultimate yang, and the result of the encounter between the two divine objects of Yin and Yang is that the soul will be filled with shock and soul powder." Gu Qingyi thought and spoke slowly, "The toner added is also of particular importance, just like the toner made of bamboo leaves is the most intense, and these subtle parts should also be thoughtful."

Gu Qingyi's mind was spinning rapidly. I wonder if it was because of eating the leaves of Xiaoyushu. Many places I read in the past have been returned to the teacher. Now, if you think about it carefully, you can remember it again.

"In all fire attacks, there are several techniques. The poisonous fire is mainly made of white arsenic, slurry, and mixed with gold juice, silver rust, etc. The divine fire is mainly made of cinnabar, realgar, orchid. The camp fire is mainly made of tung oil and rosin. Therefore, it is also necessary to repeatedly experiment with the gunpowder formula we made..."

When Gu Qingyi turned around, she saw Zheng Huanzheng writing quickly, and she couldn't help but stop.

Zheng Huan didn't hear Gu Qingyi's voice and said anxiously: "Stop talking."

What do you say!

Is there anything wrong with what she said? Are these things that are not available in this time and space yet?

She really can't remember it very clearly.

Zheng Huan looked up and saw Gu Qingyi's confused expression. He didn't know what he was thinking, and seemed to be immersed in his mind.

Zheng Huan has been so common recently. Xi Changxian always stares blankly when he thinks about key places. He often sits for an afternoon, letting you howl and scream without any effect.

It seems that Ms. Gu must have thought of something important. He wants to know a lot. Now he can leave and not disturb Ms. Gu's thinking.

What if you open your mouth and interrupt your thoughts?

Anyway, if he was thinking about something about the armillary sphere being interrupted, the inspiration would fly away instantly, and the murderous heart would be there.

Zheng Huan quietly walked away with his stuff on his toes.

Gu Qingyi:...

Really, don't be like a thief.

She just didn't understand whether she had missed something, but it didn't seem that the problem was big.

Forget it, she is not an intelligent robot, you can tell that it has been five thousand years with just a scan.

I'm so tired.

Gunpowder belongs to the category of low-explosion speed explosives. As long as you go to the Tao, it is actually very easy to make.

She had already made such a clear reminder that if she couldn't do it, she might as well roll up her sleeves.

Zheng Huan and Xi have been working hard in the gunpowder industry for a long time. A new batch of paper armor has also come out, with more than a thousand pairs. Gu Qingyi has divided 200 and sent it to Gu Yishu, and the remaining 800 people have been sent to Jizhou.

Starting from Huzhou through Lucheng, Licheng, Shexian to Wu'an, this road is very familiar. It is the way she came to Huzhou and it is also the way to pick up the emperor's uncle to Huzhou. After arriving in Wu'an, there will naturally be people from the emperor's uncle to pick him up.

Gu Qingyi transferred a large part of the remaining troops in Yuzhou to escort it. In this way, Yuzhou was really weak in defense.

Fortunately, it won’t take long to go back and forth, and something really happens, and I can wait for reinforcements for a while.

After loading the car before dawn, Gu Qingyi got up early to see everyone off, and ox carts were ready to go. Gu Qingyi watched them leave the fort, and the gray sky looked gloomy.

"Girls, Licheng, Wuxiang, Pingshun all heard good news and found iron." He ran all the way. Since he followed his young man, he learned more about his husband's ability to remain calm when encountering problems, but now he really can't hold back.
