For this automatic fan, she plans to use water energy to make the fan automatic.

Just like the last time the water truck transported water from the river to the fields, this time we also need to use a water truck, and this water truck must be larger.

At that time, it can not only be used to make fans, but also used to water vegetable gardens.

In addition, when she finds the right materials, she can make ice cubes in the summer, so that everyone can cool down before going to bed.

In the mountains, it is very cool in the middle of the night and not too hot.

This waterwheel fan is mainly used for Xu Dabao's convenience when he is studying during the day and before everyone goes to bed at night.

Su Xiaoxia entered the space and found Xiao Luo and told her her concept. After all, Xiao Luo had lived a long time and knew a lot, so she thought it was feasible and asked Su Xiaoxia to move all the materials into the space to test it out.

If possible, the waterwheel and windmill can be moved directly outside the space.

Because tools are needed to make a waterwheel fan, Xu Yiyun has not brought in the tools yet.

As a result, at this moment, Xiao Luo said: "Master, if you want tools, Xiao Luo knows where to find them. They are all left by the previous owner. Master, come with Xiao Luo."

After finishing speaking, Su Xiaoxia was led by Xiao Luo to another part of the space.

Su Xiaoxia had only been to this place before when she came in to explore the space, but she didn't pay attention because it was empty and there was nothing.

If I have to say yes, it would be that there is a large grassland here.

However, the tools that Xiao Luo mentioned were all found on this large piece of grass, and Xiao Luo buried these things underground.

"Xiao Luo, there is such a good thing in our space, why are you telling me now..." Su Xiaoxia asked curiously.

There are actually a lot of cold tools here. To put it bluntly, they are knives, hoes, axes and other iron tools. Oh, by the way, there are also editing knives and the like.

"Because I thought the owner would not need these. After all, the owner is busy taking care of the children and making money all day long. These were all used by the previous owner for entertainment in the space."

"Pastime? Why do you have to have fun in space? What did your previous masters have to do in real life?" Su Xiaoxia frowned, thinking that they were just messing around and waiting to die, right?

As a result, after Xiao Luo answered, Su Xiaoxia guessed correctly. After obtaining the space, those owners relied on the spiritual spring water to live a long life, but they spent their whole lives growing things in the space and selling them.

Only she, Su Xiaoxia, is different. After getting the space, she doesn't use the space so much. She only comes in when needed, instead of holding on to the space like a life-saving straw, just treating it as a part of herself.

"So, after my death, you will usher in the next master?" Su Xiaoxia asked.

Xiao Luo shook her head: "Xiao Luo doesn't know either. Xiao Luo only knows that you are different from the previous master."

"Oh... forget it, I don't want to go so far. Since we have the tools, let's quickly test my idea." Su Xiaoxia said, then selected the tools that were handy and the tools that needed to be used, and returned to Lingquan again.

There happens to be a water source there, and as long as Xiao Luo operates it, the spiritual spring water will overflow and form a stream.

Once again, it was familiar. She had already made a waterwheel before, so this time Su Xiaoxia was particularly skilled. After a while, she made a two-meter-high waterwheel using the trees in the space.

The next step is to make the bearings. If you are not a professional in this field, you must be someone who is good at observing in real life.

And Su Xiaoxia is that kind of person who is curious about some weird things and then stares at them for a long time.

She can see ten lines at a time, and she can remember things with a photographic memory, let alone things she keeps staring at.

This requires close specification calculations. Although Su Xiaoxia studied medicine in her previous life, it does not mean that she is not proficient in other subjects. At least she is good at mathematics. Although she cannot reach the level of the first in the world's Mathematical Olympiad, it is more than enough for calculations.

Xiao Luo helped make it, while Su Xiaoxia used the ground and branches to calculate the required size.

The east room and the west room are not opposite, but adjacent, so if you want to make a fan, you need to make two of them together, and you also need to place fans at the windows of the two rooms.

The two rooms in the east room are connected, so we only need to remove the partition between the two small rooms so that Shen Lan and the children can stay cool.

If there are many people and the room is large, a fan that can blow strong winds is needed, which means that the fan blades need to be larger.

So, Su Xiaoxia was immersed in her own calculations, and once she figured it out, she asked Xiao Luo to start making it.

Although Xiao Luo looks like a loli, with purple-blue hair and a slender figure, her strength is not small. It can be said that she can do whatever she wants in the space, but she cannot judge the master and has strange thoughts.

"Master, do you think this is okay?"

Hearing this, Su Xiaoxia looked up and found that Xiao Luo had spliced ​​the fan blades together and supported them on a tripod.

"It looks good." Su Xiaoxia put down the branch in her hand, stood up and pushed it gently with her hand. The fan blades slowly rotated in circles driven by the gear bearings.

I have to say that Xiaoluo’s hands-on ability is really no worse than that of humans!

"Xiao Luo! You are great!"

"Thank you for the compliment, Master!" Xiao Luo chuckled, "Being able to be needed by the Master and also able to help the Master is the biggest compliment Xiao Luo has ever felt!"

Hearing this, Su Xiaoxia reached out and touched Xiaoluo's head, "Now that the fan blades and tripod are made, the next step is the bearings on the waterwheel that drive the two fans to rotate. I have already done the calculations, now let's start Let’s do it!”

"Okay!" Xiao Luo nodded happily, and then followed Su Xiaoxia to help.

With the data in hand, the bearing will be ready in a short while.

However, there is a problem now. She is thinking about it. Bearings and gears are usually covered with belts, that kind of very hard synthetic tape to drive the two bearings, or a certain amount of iron chains, just like motorcycles and bicycles. The same as the bicycle chain.

But in this era, it is obvious that there is no such bearing belt. Even if there is, it is difficult to make...

Xiao Luo understood Su Xiaoxia's worries and said with a smile: "Master, don't worry, Xiao Luo has a solution!"

"Huh?" Upon hearing this, Su Xiaoxia's eyes were filled with joy, but she was more curious.

Xiao Luo disappeared in front of her, and then flashed back a moment later, with a few vines in her hand, which seemed to be some kind of plant.

But Su Xiaoxia, who claims to have seen a lot of plants, was still confused after seeing the vine on Xiao Luo's hand, "Xiao Luo, what kind of vine is this?"
