In the room where Han Cheng was in Jinguan City, not only Han Cheng was confused at the moment, but Han Youyue was also equally confused.

Wasn't everything fine before?

How come everything has changed now?

I have been so excited and looking forward to this for so long, I have even come to your house and taken off my animal skins, and you tell me, did I misunderstand?!

This is simply not happening?!

How can this be like this!

"You, you kept looking at me, I, I said I would come back to sleep, you, you said okay..."

Han Youyue looked at Han Cheng, appeared anxious and somewhat aggrieved, and explained.

"Wrap the animal skin around yourself first."

Han Cheng said to Han Youyue that he just felt a headache.

What the hell is going on!

I was not looking at you. I was clearly looking at the water mill, and then thinking about how to update the tribe's water mill and make a better one that is more suitable for the tribe.

How did it become just looking at you, not knowing what was going on, and then developed into wanting to put you to sleep?

It is such a serious and great thing to update the tribe's water mill and make a significant contribution to the tribe!

How come it has changed now, becoming so indecent and vulgar?

Han Dashenzi, who was stunned by the headache, suddenly had the urge to remain speechless.

How did this happen?

Why did it become like this when I, the person involved, knew nothing about it?

Han Youyue, feeling aggrieved, picked up the animal skin that fell on the ground reluctantly and wrapped it around himself following Han Dashenzi's orders.

Then he still looked at Han Cheng with aggrieved, confused and anxious look.

Han Cheng rubbed his forehead vigorously with his hands, and then began to explain the matter to Han Youyue.

"I was looking at the water mill, thinking about how to make the tribe's water mill better... I thought you got up too early and were sleepy, so I wanted to come back to sleep..."

In the awkward atmosphere, Han Cheng kept explaining to Han Youyue.

After a while, Han Youyue walked out of the house where Han Cheng lived, his face red.

This was certainly not a mark left by something she had experienced, but because she felt particularly uncomfortable and embarrassed for her misunderstanding of the Son of God's intentions not long ago.

I thought I had seen through the Son of God’s intentions, and I was proud of it for a long time. I thought that during this period of time, I had become the person who understood the Son of God the best. But I didn’t expect that my understanding was so far away from the Son of God’s intentions...

Shenzi was thinking about how to make a water mill that would be more useful to the tribe, but he was thinking about the issue of sleepiness...

In the room, with Han Youyue's departure, the awkwardness that was so strong that it seemed almost unsolvable gradually faded a lot.

Han Cheng, who was sitting in front of the desk, rubbed his head and smiled bitterly.

What's going on every day?

Long before he met Sister Bai Xue, he had once been in deep thought, which led to people like Xiao Mei and Xiao Li wanting to offer themselves to her.

Now that so much time has passed and he has become the father of two children and an unborn child, it was for a similar reason that Han Youyue ran into his house and stripped off the animal skins that were surrounding him, wanting to...

Does this mean that from now on, when I go out, I can't open my eyes to see the road, and I need to keep my eyes closed the whole time?

Then tie a rope to the lucky general and let him lead you and bring the cat down for you?

Or should I find a way to get a pair of sunglasses, wear them on my eyes, and wander around the tribe**?

In the same way, no one will think they are looking at her anymore!

Han Dashenzi sat here, daydreaming about nothing.

"Alas~"

After a while, Han Dashenzi sighed deeply, looking particularly sad and uncomfortable.

This person is just too good!

Just when I was stunned for a moment, someone came over to offer himself to me. Such charm is really beyond words.

This matter is really too annoying!

What should I do in the future to reduce my charm a little bit?

How can I avoid becoming so attractive and being liked by the women in the tribe?

After thinking about it for a while, Han Dashenzi sighed heavily again.

Because he found that he couldn't do such a thing at all!

This task is even more difficult than making the updated water mill!

"Alas~"

Han Cheng sighed heavily once again. Why is it so difficult to become less outstanding?

A certain son of God demonstrated to the fullest what it means to be shameless!

After thinking about it dejectedly for a while and realizing that this was an unsolvable problem, Han Cheng stopped worrying about it.

He picked up his pen and began to continue what he had not done before, working hard on the new water mill...

"Alas~"

Han Cheng sighed heavily again.

Because during this period of time, he didn't write much.

The image of Han Youyue untied the animal skin and standing in the room kept wandering in his mind and could not be shaken off.

In fact, to be fair, Han Youyue's appearance is more in line with modern people's aesthetics.

She is much slimmer, not as strong as Zhuang, Ruhua and others, and the lines on her face are softer.

If it were not for this, Han Cheng would not have named her "Yue" and let her do the relatively light work of pounding rice with a water pestle.

Han Cheng shook his head vigorously to get rid of the mess out of his mind, then picked up the pen and continued writing.

But the effect was not good at all. He still had no ideas and could not write anything.

After repeating this for five or more times, Han Cheng sighed once again, placed the pen in his hand on the pen holder made of pebbles, rubbed his hands vigorously on his face, paused for a moment, stood up from the chair, turned around and walked towards the door...

"Squeak~"

With a creaking sound, the door that had just been open was closed by Han Cheng.

Just closing it was not enough, so Han Cheng plugged it in from the inside.

After doing these things, Han Cheng came to the desk again and sat down in front of the chair...

"Squeak~"

The door that had been closed for a while opened from the inside and Han Cheng walked out.

He walked to a nearby place, washed his hands and face with clean water, without wiping them, and walked slowly towards the house with water droplets on his face.

At this moment, Han Cheng felt relaxed and refreshed.

After returning to the house, he sat down at the desk again, picked up his pen and started working on the things he had not finished before.

After eliminating some particularly uncomfortable interfering factors, Han Cheng felt that his thoughts were extremely clear.

Once a person's mind is clear and his thoughts are flowing, inspiration will come and it will be easy to get something that he couldn't get before.

Just like Han Cheng now.

Before, he wrote and drew on paper in order to find out how to make the key parts of the water mill.

But there has been no breakthrough progress.

But now, with a clear mind and a happy mood, I have just sat here for a short while and inspiration suddenly came to me!

An object suddenly appeared in Han Cheng's mind, making Han Cheng excited.

More exciting than just now!

The thing that appeared in his mind was nothing else but a huge waterwheel that was turning driven by the running water!

As the waterwheel turned, bucket after bucket of water was lifted from the pool and poured into the canal, then flowed happily along the canal into the distance...

What Han Cheng wanted to make was a water mill, but what he thought of at this moment was a waterwheel. There should be no connection between the two, so Han Cheng didn't need to be so excited.

But Han Cheng was so excited at this moment that he could hardly control himself!

Because he had found what he wanted from the rotating waterwheel!

What has always troubled him the most is how to use the running water to make the shaft inside rotate.

Now, with the waterwheel, everything suddenly becomes clear!

All you have to do is lengthen one side of the waterwheel's axle!

This rotating shaft can drive the water mill to operate!

Han Cheng became more and more excited as he thought about it while sitting here. After waiting for a while, he picked up a pen and started writing quickly.

It may not be possible to copy the water wheel, and it is not suitable for the water mill, but I already understand the principle now.

Once you know the principle, the rest will be easy.

Based on this principle, we can make improvements on the waterwheel to make it more suitable as a water mill!

After more than half a day, Han Cheng had basically finished getting these things done.

After sitting here, drinking two sips of mint water and stretching nicely, Han Cheng took the things he had written and drawn in his hands, walked out of his room, and went to look for Mao Er.

Mao Er, the young carpenter who was encouraged by Han Cheng's inkstone, has now become very mature.

Among all the craftsmen in Jinguan City, his skills are the best and most advanced.

It was precisely because of this that Han Cheng asked him to be the team leader of the Jinguancheng Carpenter Group, leading the carpenters in the tribe to do various things.

When Han Cheng came over, Mao Er was busy here.

He held the 'ears' of the plane with his hands, one on each side, his back slightly bent forward, and was working hard to flatten the wooden board placed on a tall, simple four-legged stool.

Every time you push forward with force, some shavings will appear in curls, then flow out of the plane hole and fall to the ground.

Through his actions, this side of the wood soon became flat and smooth.

What he was working on now was the front crossbeam of the ox cart frame.

Three oxcarts with cat ears have been made, and the fourth one is being made now.

As there are more cows in the tribe, ox carts must keep up.

Oxen are strong, so ox carts are big and can pull a lot of things at once. Whether they are used to transport food or soil, they are very useful, so naturally more of them should be made.

In addition to Mao Er, there are nearly twenty other people busy here.

Some of these people were working in groups of two, pulling large saws to cut the boards, while others were drilling holes with hammers and chisels in their hands.

Unlike Maoer who was making car frames, these people mostly worked on doors, windows, tables and chairs.

It was for the tile house that was under construction.

In addition to making doors and windows, there were several people weaving fences there using some soft branches.

This is laid on top after the house is built and the beams and rafters are installed.

"Son of God."

"Son of God."

…

When Han Cheng arrived, everyone who was busy here greeted him with a smile.

Seeing this, Han Cheng smiled and nodded to them.

“Look at this.”

Han Cheng walked all the way to Mao Er, handed the paper in his hand to Mao Er, and said to Mao Er with a smile.

When Mao Er saw the paper in Han Cheng's hand, he felt excited and expectant.

After hearing Han Cheng's words and confirming his guess, he became even more excited!

As the direct disciple of Lame, the first carpenter in the tribe, Mao Er naturally knew what the Son of God brought, and he also understood what this thing and the behavior of the Son of God meant to him!

This means that his skills have been recognized by the Son of God!

It is a great affirmation of myself!

After all, this kind of thing of making new objects was previously the patent of Bo!

At this time, the Son of God handed the case over to him to deal with. Although one of the reasons was that Bo stayed in the main tribe and did not come, this was also a great affirmation of himself!

At that moment, Mao Er, who was in an excited mood, rubbed his hands vigorously on his body, then quickly stretched out his hands, took it, and then looked at it carefully...

"The water-powered mill in the tribe is too slow for pounding rice, so I plan to make a new kind of water-powered mill.

This water mill has a relatively complex structure, but it is very easy to use.

One shaft can drive at least two hammers to move up and down to pound rice.

Moreover, the frequency of the hammer's up and down movement is also high..."

After Mao Er looked at it for a while, Han Cheng spoke to Mao Er and explained to him what it was, what it was used for, what the effect would be after it was made, and how much significance it would have for the tribe.

Knowing these things will help Mao Er to have peace of mind.

It is more exciting to do and easier to find ideas.

After telling this, Han Cheng explained to Mao Er how the water mill works under the action of water flow and how some of its components are roughly connected.

Many of these things cannot be clearly described in pictures, or are difficult to record or describe. If Han Cheng tells them in person, it will be clearer and more convenient, and more conducive to Maoer's understanding...
