I am a primitive

"Son of God!"

On the way here, the two of them already knew roughly what Han Cheng called them to come from their lameness, so after they came to Han Cheng and said hello, they began to look at Han Cheng with piercing eyes, waiting for Han Cheng to start getting off. Send tasks.

Han Cheng was very satisfied with the attitudes of several people, and immediately took a piece of paper, a charcoal pencil, and things like rulers and compasses, and began to draw two wheels connected by bearings on the paper.

After finishing the painting, I also said some of my own opinions on it.

As for the wheels, Han Cheng's most memories come from when he was a child with a few friends in the village. He went around the room and unloaded from the car, one wheel landed on the ground, and the other wheel flew into the air. matter.

Hold it with your hand, and then push it hard, and the ox cart wheel on it will rotate.

At an age that lacks toys, Han Cheng can play with such fun things for most of the day without getting tired of them.

It's just that the ox cart wheel tires at home are made of rubber, and where the bearing and the wheel are connected, in addition to the steel sleeve, there are small steel balls between the inner sleeve and the outer sleeve.

These things mixed with engine oil will reduce the friction between the wheel and the axle, making the cart more light and stable.

There is still a huge gap between knowing these and making them, but at least you can know where you need to work hard.

Han Cheng pointed to the sketches he had drawn and told several people there. Among them, Lame and Hei Wa understood the fastest, while the second senior brother, a coppersmith who became a monk on the way, was much slower. Compared with the two children, it is much more difficult to teach.

It's just that during this process, you still have to have a pleasant face and a good mood, otherwise, such a big man who looks extremely mighty and majestic will show a look of crying, which makes people feel a little unbearable.

Fortunately, for things like bearing collars, the most important thing is Hei Wa, the mold maker. He just needs to make the mold, and the second senior brother will pour it out step by step.

The discussion about the donkey cart lasted until the sky was about to darken, and then it was considered to be completely over.

And when it was over, there were several more people in the conference room. They were all leaders of the Qingque tribe who came over by themselves after hearing some news.

For example, Senior Brother, Shang, and Mao.

Everyone who came out of the meeting room couldn't hide their excitement. They wished they could ride in that kind of two-wheeled cart pulled by a donkey.

The second senior brother, Lai, and Heiwa, the backbone technicians, rolled up their sleeves eagerly.

If it weren't for Han Cheng's order to sleep well and get enough energy to try again tomorrow, these guys would definitely be able to do something like a night battle...

"Brother Cheng, what is a donkey cart?"

When sleeping at night, Bai Xuemei, who was lying on the kang, asked Han Cheng aloud, full of curiosity.

"It is a cart that puts the sledge close to the left and right sides of the middle, installs a large wheel on each side, and then puts on a donkey, and lets the donkey pull it."

Han Cheng explained aloud.

After thinking for a while, he said again: "When the donkey cart is built in the Time Tribe and the road leading to the Tongshan residential area is also built, we will put on the donkey cart and load it with canned food, dried meat, For things like millet, pots and bowls, I will drive the car, and you and Xiao Wandou will sit in the car, and then you will take Fu Jiang and Tuantuan to play in the Tongshan residential area.

Show you the blue pool on the Copper Mountain..."

In later generations, when you are picking up a girl, if I say that I will take you and your children to see the outside world in the ox cart at home, then in all likelihood, I will give up, and I will give you a white stare at that time, and then Turn around and leave.

Still want to bring the kids?This is simply what happens in dreams.

But now it's completely different.

After Han Cheng sacrificed this kind of donkey cart that doesn't even have a car key that can be dropped straight down from the waistband, and said that it is time to take her and the child out to play, Bai Xuemei was very happy. Hugging Han Cheng's arm, his eyebrows and eyes were full of stars.

In this way, Han Cheng sighed once again, if the majority of single comrades in future generations know that it is so easy to find a wife at this time and the requirements are so low, I don’t know if there will be a wave of going to the Gobi Desert, and then use their hands. Go touch that petroglyph craze...

According to Han Cheng's guess, if he travels far enough, he might be able to find a fair-skinned, beautiful woman with long legs that could crush a watermelon, and blonde hair and blue eyes as his wife.

Of course, the premise is that they can survive in such an era, and not become food for wild beasts, and drag them to take a bath...

On the second day, the people in the tribe got up very early, and many people had dark circles under their eyes. Among them were the three main personnel who built the donkey carts, Lai, Heiwa, and the second senior brother, and those who were sitting on the donkey cart. The excited and sleepless Bai Xuemei and the others who went out for an outing in the donkey cart were the most obvious.

So much so that when the two chubby guys, Tuantuan and its mother, came over, they were confused for a long time, then silently hugged the bamboo in their arms, turned and left without a word...

"Chi Chi ~ Chi Chi ~"

Outside the carpenter's room, two apprentices brought out by a lame hand stopped weaving the rattan armor, and were pulling the saw hard, sawing down the straight line drawn with charcoal and a ruler, and sawing with the fine sawdust. It fell down one after another, and a piece of wood standing there was gradually disintegrated into planks.

Lame squatted aside, chopping a piece of wood with a bronze ax in his hand.

The sledge is similar to the upper part of the donkey cart, but there are still some differences after all.

Moreover, it is a pity to destroy a good sledge and change it into a donkey cart. In addition, such things as copper casting axles cannot be manufactured in a short time, and there is plenty of time, so the lame is prepared on the basis of manufacturing the sledge. According to some suggestions that Han Cheng said yesterday, a donkey cart was rebuilt.

After you get this new donkey cart out, go get the wooden wheels...

In the pottery room, Heiwa was squatting there and using the reconciled mud to make molds. This new mold was not very smooth to make. After a while, he would look at the two pieces of paper not far away.

On it are the shapes of two wheels connected by bearings drawn by Han Cheng, as well as the appearance of individual bearings.

After looking at it for a while, I turned back and continued making molds.

In the process, he destroyed many semi-finished molds made of mud.

Squatting aside to help make mud is Wu's hand warmer Baoyuan. For pottery, Yuan, who used to make pottery in the Bannong tribe, has a deep obsession.

Therefore, when she came to the Qingque Tribe, and saw Heiwa started making pottery with clay, she would lean over and watch with piercing eyes.

After watching a lot, I will slowly start mixing mud and try to make pottery.

With Heiwa, a master pottery maker, Yuan has benefited a lot from it. Compared with before, the level of pottery making has been greatly improved...

"Ah~"

An apprentice carpenter holding a long ruler made of wood in one hand and a charcoal pencil in the other to draw straight lines on the wood couldn't help sighing.

Because he accidentally drew a crooked line just now, this is the third time he has drawn a crooked line.

The line is crooked. If it is not corrected, the whole piece of wood will become waste after the wood is opened along this line, so the little apprentice can only find a broken rag, stick it in water and continue. wipe.

After finally wiping it clean, he drew it wrong again, which almost made the little apprentice jump on the spot angrily and anxiously.

Because there is only a small half of the last piece of wood being sawed, and it will be finished in a short time. If the painting is done well, then the work will be delayed.

And there is also the possibility of being blamed by the master.

The little apprentice was anxious and wanted to draw these lines quickly, but the more anxious he was, the more mistakes he made.

Seeing that the rest of the wood was about to be untied, and he hadn't finished drawing the line on the pillar, the little apprentice was crying anxiously.

"Why haven't you finished drawing yet?"

The lame man who was chopping a pillar with an ax over there couldn't hear the sound of the big saw. He looked up and saw that the two people who pulled the big saw had stopped, and they were standing on the side of the man who was in charge of marking the line. The little apprentice looked in front of him, and the little apprentice wiped away tears anxiously, and immediately knew what was going on.

Immediately, he frowned and asked aloud, with some sternness in his voice.
