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

Just like the last time the waterwheel carried water from the river to the fields, this time it was with the help of a waterwheel, and this waterwheel had to be larger.

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

In addition, when she finds the right ingredients, she will be able to make ice cubes in the summer, and everyone will be able to cool down before bed.

In the mountains, the second half of the night is very cool and not very stuffy.

This waterwheel fan is mainly for the convenience of Xu Dabao when he reads during the day and before everyone goes to bed at night.

Su Xiaoxia entered the space and found Xiao Luo and said her own concept, after all, Xiao Luo has lived for a long time and knows a lot, so she thinks it is feasible, so she asked Su Xiaoxia to move all the materials into the space to test it.

If you can, you can move the waterwheel windmill directly outside the space at that time.

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

As a result, at this time, Xiao Luo said: "Master, if you want tools, Xiao Luo knows where they are, they are all left by the previous master, and the master will come with Xiao Luo." ”

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

This place, Su Xiaoxia had only come to explore the space before, but she didn't care, because it was empty and there was nothing.

If I had to say that there was, it was a big meadow.

However, the tools that Xiao Luo said were all under this big grass, and Xiao Luo buried these things underground.

"Xiaoluo, we have such a good thing in our space, why are you only telling me now......" Su Xiaoxia asked curiously.

There are a lot of cold tools here, to put it bluntly, knives, hoes, axes, these iron tools, oh yes, there are also carving knives and the like.

"Because I thought the owner wouldn't need this, after all, the owner was busy taking care of the children all day long, busy making money, and these were all used by the previous owner for recreation in the space."

"Pastime? Why do you want to spend time in space? Did those previous masters of yours have nothing to do in real life? Su Xiaoxia frowned, thinking to herself that it could be a rotten master who was eating and waiting for death, right?

As a result, after Xiaoluo answered, Su Xiaoxia really guessed correctly, after those masters got the space, they relied on the spiritual spring water to live a hundred years, but they planted things in the space and sold them, and spent their lives like this.

Only she Su Xiaoxia is different, after getting the space, she doesn't use the space so many times, and she will only come in when she needs it, instead of holding the space tightly like a life-saving straw, just treating it as a part of herself.

"So, after my death, you'll have 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 do so much, now that I have the tools, let's quickly test my idea. Su Xiaoxia said, then picked out the tools that he had and the tools he needed, and returned to Lingquan again.

There is a water source over there, as long as under Xiao Luo's operation, the spiritual spring water overflows into a small stream.

Once raw and twice ripe, he had already made a waterwheel before, so this time Su Xiaoxia was extremely skilled, and after a while, he made a two-meter-high waterwheel from the trees in the space.

The next step is to make bearings, if you are not a person in this related profession, you must be a person who is good at observing in real life.

And Su Xiaoxia is such a person, she is curious about some strange things, and then she will stare at it for a long time.

She can see ten lines at a glance, and she can never forget it, let alone what she keeps staring at.

Although Su Xiaoxia studied medicine in his previous life, it does not mean that he is not proficient in other subjects, at least mathematics is still good, although it does not reach the first level of the global Olympiad, but it is more than enough for calculation.

Xiao Luo helped with the production, while Su Xiaoxia used the ground and tree branches to calculate the required size.

The east and west houses are not opposite, they are adjacent, so if you want to make a fan, you need to make two of them, and you also need to place fans in the windows of the two houses.

The two rooms in the east room are connected, so when the time comes, only the partition between the two small rooms needs to be removed, and Shen Lan and the children will be cool at that time.

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

So, Su Xiaoxia was immersed in her own calculations, and as soon as the calculations were completed, she let Xiaoluo start to make them.

Although Xiao Luo is Lori, her hair is purple and blue, and her body is slender, but her strength is not small, it can be said that in the space, it can do whatever it wants, but it just can't judge the Lord and have a different mind.

"Master, do you think this will work?"

Hearing this, Su Xiaoxia looked up and found that Xiao Luo had already spliced the made fan blades, and then supported them with a tripod.

"Looks good." Su Xiaoxia put down the branch in his hand, got up and went over with a gentle push with his hand, and the fan blades slowly rotated under the drive of the gear bearing.

I have to say that Xiao Luo's hands-on ability is really no worse than that of humans!

"Little Luo! You're amazing! ”

"Thank you host for the compliment!" Xiao Luo smiled, "Being able to be needed by the master and helping the master is Xiao Luo's greatest convincing since she was conscious!" ”

When Su Xiaoxia heard this, she reached out and touched Xiaoluo's head, "Now that the fan blades and tripod are made, the next thing is the bearing on the waterwheel that drives the two fans to rotate." I've done the math, now let's get started! ”

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

With the data, it didn't take long for the bearing to be made.

But now there's a problem, she's pondering, the bearings and gears are usually belts, the kind of very hard synthetic tape that drives the two bearings, or a certain amount of iron chains, just like the chains of motorcycles and bicycles.

However, in this era, it is clear that there is no such bearing belt, and even if there is, it is difficult to make it......

Xiao Luo knew Su Xiaoxia's worries, and said with a smile: "Don't worry, master, Xiao Luo has a way!" ”

"Huh?" Hearing this, Su Xiaoxia's eyes were happy, but more curious.

I saw Xiao Luo disappear in front of her, and then flashed again after a while, with a few more vines in her hands, which seemed to be some kind of plant.

But Su Xiaoxia, who boasted of having seen a lot of plants, was still at a loss after seeing the vines in Xiao Luo's hands, "Xiao Luo, what kind of vine is this?" ”

"This ...... I don't know, yes, it was left by the previous owner. When Xiao Luo said this, her head was lowered, and her eyes were a little weird.
