Regarding Wang Jianshu's words, Mo Mo patted his head, he was negligent, and he didn't tell them the purpose of the waterwheel all along.

Just like the skilled workers who make auto parts, if they don't know what the workpiece they process is used for, they will make a lot of mistakes and omissions in the process of production, such as making key workpieces, but workers don't know its use, even if there are drawings (it is normal for design drawings to have errors and omissions), some workers tamper with them privately, or make themselves smart, and the final processed workpiece does not meet the design requirements, or it is too much, and waste energy.

For another example, if the clerk writes a report for the leader, if he does not know the leader's intentions, no matter how well he writes, it is not in line with the leader's appetite.

Mo Mo inspected the waterwheel and found the above problems, some of the processing parts on the waterwheel are too fine and unnecessary.

Originally, Mo Mo planned to install a water wheel in the Blue River near Qingyuan Village, but with Caigu, he changed his original idea.

"Our current arrow shaft lathe power is too small, processing has a great limitation, if the waterwheel is the power, there will be no need to step on manpower in the future, the waterwheel capacity can drive a larger lathe. Mo Mo and Wang Jianshu sat opposite each other, holding a stone pen, and said while drawing on the ground, Mo Mo explained for a long time before he understood the principle of waterwheel power.

"The most important thing is that our wood is too difficult to process into planks, you have to plane slowly, and the processing is rough. If there is a waterwheel driving a large machine, you can directly cut the wood into a film!" Mo Mo drew and decomposed on the ground again, and Wang Jianshu quickly understood the work of a carpenter.

Mo Mo's meaning is to use the water flow as the power to drive the waterwheel, and connect it to drive the lathe and sawing machine.

The sawing machine can process large wood in flakes, which can solve the long-standing problem of making wooden boards.

Mo Mo's space is too small, otherwise he would have moved generators and sawing machines directly from the earth, why would he still use such trouble.

"Uncle Wang, pause the work of building wooden houses, the wooden houses that have been built so far are enough. We first set up the waterwheel, made the sawing machine, and when we were able to process the boards, we went to make the wooden house much faster. Mo Mo commanded, and then left the carpenter's room.

In fact, if Zhengtu Group could produce cement, Mo Mo would not be so troublesome.

The main raw material of cement is easy to find, it is available in Caigu, and the production process of cement seems simple, but it is not easy to produce it. The conditions above 1400 °C required for the sintering of materials in the light kiln require a lot of preparation work.

After the waterwheel is installed and Caigu settles down, cement production may be the next major work of Zhengtu Group.

At the same time, with cement, it is much easier to build an iron-making blast furnace.

Mo Mo came to the blacksmith's room, and he mainly came to inspect the making of the saw.

If it is a small-diameter saw, Mo Mo can directly purchase it from the earth and send it to the other world, and the ones he buys are all very tough and not easy to break his teeth.

But with a large-diameter saw, Mo Mo couldn't carry it to the other world. Mo Mo bought steel from the earth and transferred it to the other world, let the blacksmith forge it into a large round cake, first make a zigzag outline and then grind it, then quench it locally to ensure the hardness of the sharp teeth, and finally draw a circle center on the round cake and drill it with a drilling tool. Large-diameter saws are mainly used to cut large pieces of wood.

Mo Mo walked around the blacksmith's room and found that there were many small problems in the workshop, but there were no major problems.

Mo Mo left the blacksmith's house, took the horse back to the stable next to the wooden house, found a hidden place, and turned back to Earth.

……

Earth.

Mo Mo returned to his villa in Pingzhou, had nothing to do, played with wood carving, and planned to carve an agarwood pendant for each family member.

At nine o'clock the next morning, as soon as Mo Mo finished practicing martial arts, someone called.

"Brother, are you back? The newspaper said that you have returned to China, returned to Yangcheng, are you in Pingzhou?"

Mo Mo took the phone, and there was a crisp and sweet voice in his ears, and he knew that it was Yu Xiao's little girl's voice.

Yu Xiao sometimes she is like a little sparrow, chattering and asking endless questions, as if there are endless questions, and Mo Mo is also very helpless.

The recent news about him is really hot, all kinds of strange and outrageous reports, Mo Mo feels disgusted after reading it.

Hey, don't praise me for being good, I have a system!

When she came out of the airport, the reporter saw it, and it was probably reported by the local media again, probably her parents told her.

As soon as Mo Mo heard Yu Xiao's tone, he knew that this little guy was going to pester him to play again, so he had to be an honest child and said, "Well, I'm back, sleep at home." ”

"Brother is so lazy, the sun is out, and the sun is getting to the buttocks. Brother, this weekend, take Xiaoxiao to the cinema to watch cartoons, okay? My mother is busy, my father doesn't like to watch it, saying that cartoons are too naïve, in fact, where do they understand the thoughts of our children, big brother, don't you say?"

Mo Mo couldn't help laughing, he really wanted to say to Xiaoxiao, I don't understand your childish thoughts.

Mo Mo shook his head and patted his head, thought about it, and estimated that he couldn't resist this pestering little guy, so he still agreed, and said, "Okay, my brother will take you to play later." In his previous life, his niece was like Yu Xiao, pestering him all the time.

Mo Mo hung up the phone, changed his clothes casually, and didn't even bother to bring his bag, only bringing money, door keys and mobile phones. When she arrived at Yu Xiao's house in Minghua Community, she saw that the family was at home, said hello to her parents, and took Yu Xiao out.

Today's weather is hot, Yu Xiao wore a powder blue skirt, a small whip, and a small bag, and got the consent of her parents, and went back to the house to dress up before pulling Mo Mo out.

Along the way, Yu Xiao was like a little elf, really excited, his eyes were crooked like a crescent moon, as if the spiritual rhyme was overflowing, walking in a circle around Mo Mo, and singing "Let's Swing Double Pulp", the voice was crisp and loud, as if there was an aura, which made Mo Mo feel relaxed and happy.

"Big brother, I've learned to walk the swan step, you see. Yu Xiao walked in front of Mo Mo, and after speaking, he made a "heart" shape with his hands on the top of his head, stood on tiptoe with his legs, walked forward in broken steps, stepped on a small pit, stumbled, and almost fell.

"Hehe, is it good-looking?" Yu Xiao looked back, his big eyes were tactful and smart, revealing two rows of white teeth like broken jade, and asked with a grin.

"Well, it's pretty!" Mo Mo replied without wanting to dampen her confidence, in fact, it looked like a penguin walking, but it was very cute.

Mo Mo walked, Yu Xiao jumped up, and after a while, the two of them walked to the gate of Minghua Community, Mo Mo stopped a taxi and went directly to the city center.

The two went to the cinema first, and there happened to be a cartoon schedule, Mo Mo bought a ticket, bought some snacks, and took Yu Xiao into the cinema to watch it.

After watching the movie, it was already noon, but Yu Xiao didn't want to go home, so Mo Mo reluctantly called her mother and said that she was eating out. After lunch, Yu Xiao went to the botanical garden again, Mo Mo could only accept it helplessly, like a little bodyguard following her, holding a drink in one hand and a snack in the other.

An hour later, the two walked around the botanical garden for most of the time.

"Brother, I'm tired of walking, and my leg hurts a little. Yu Xiao squatted down and rubbed her calves, she walked for nearly an hour, she really couldn't walk, and looked at Mo Mo who was still energetic, self-evident.

"Oh, I'm sorry, my brother will carry you. "Mo Mo patronized himself, he was in good physical condition, and he didn't take into account a girl's physical fitness.

Mo Mo carried Yu Xiao to a wooden chair in the park, asked her to sit on the chair, took off her shoes, saw her red and swollen ankles, and helped her rub them with some self-blame.

Yu Xiao leaned back in the chair, eating ice cream with a look of enjoyment, every time he took a bite, he let out a comfortable "ha", and smashed his little mouth again, staring at Mo Mo.

"How much?" Mo Mo rubbed it for a while, seeing her pursed her small mouth, her eyes slipping, as if it didn't hurt anymore.

"Well, it's better, but it still hurts a little. Xiaoxiao nodded happily, stood up and jumped twice, feeling much more comfortable, two sweet dimples appeared on her cheeks, and said, "Thank you, brother!"

"Look at what you're eating, your little mouth is full of cream. You sit here first, and I'll buy you some napkins. Mo Mo touched his pocket, found that the napkins he was carrying had been used up, looked around, and saw a small shop a hundred meters away.

"Okay, I'm not leaving. Yu Xiao leaned back on the wooden chair, and her two calves took turns bouncing the wooden chair to soothe her still painful calf muscles.

Mo Mo trotted over to the shop, bought water and paper, and when he came back, he saw a young and middle-aged woman pulling Yu Xiao, followed by a young and middle-aged man.

Mo Mo frowned thoughtfully, his face changed suddenly, and he hurriedly ran over.
