I am a Primitive Man

I found the crux of the problem, and then I can do more.

Han Cheng rekindled the iron-strike stove, took off the wooden handle behind the iron saw, and put it back in the stove and burned it again.

Take out the hot red, with the saw edge facing up, and clamp it vertically between two stones, and then use an iron chisel to tilt the irregular and small serrations to the left and right.

In fact, the best way to grind the teeth is not to hold it on the grindstone as before, but first use a saw to make a cut that is not too deep on a log or stool.

Then take the saw out and turn the saw upside down, with the saw blade facing upwards, and it is stuck in the saw gap.

Then use the iron frustration to start attacking the small zigzags.

However, because the blue bird tribe currently has too little iron, every piece of iron should exert its effect to the greatest extent. It is impossible to make a special iron frustrate for the purpose of sharpening the saw, so it can only temporarily use the grinding stone. Grind.

"Chish~"

"Chish~"

The iron saw handle was held in a lame hand, pushing and pulling back and forth. There were fine sawdust, which ran out of the saw with his pull, and fell on the ground sporadically, gathering into a small pile of sawdust.

The saw after the transformation does not appear to be clamped, and it is used to saw wood very smoothly.

The first carpenter was lame, like a child who got a new toy, sawing wood with a saw, and couldn't stop at all.

It is said that the saw was invented after the legendary carpenter Luban went into the mountains to chop wood and was cut by thatch.

Now that he has the existence of the traverser himself, the lame man who is drifting away and slowly rising toward the carpentry industry has not been dragged by the grass, and then has an idea to invent the opportunity of the saw.

"Click"

The hard wood finally couldn't stand the torture of the saw, and was chopped off at the waist, and it was cut into two pieces at once.

The fracture is very flat, and it feels hot to the touch.

This is rubbed by a saw.

Squatting limp on the ground, looking at the incredibly flat wooden incision, with admiration and emotion on his face.

Such a flat incision was something he had never thought of before.

The speed of progress was much faster than burning with fire, which also surprised him with emotion.

Iron tools are so easy to use!

This is his heartfelt emotion.

The lame man with a saw in one hand and an axe in one hand, looking at the wood on the ground, became extremely confident. With these tools, he would be able to make something more usable and beautiful!

"Brother Cheng, what is this?"

Bai Xuemei squatted aside, pointed to the broken wood and asked curiously.

The lame wielding an axe also slowed down, wanting to hear what the **** child said.

There will be circles in the wood, which they only discovered recently.

In the past, the wood was cut, the thin piece was broken by hand, and the thick piece was burned with fire. The cut has never been flat, so the annual rings in the wood have never been found.

"This is an annual ring."

Han Cheng said with a smile.

"Annual ring?"

"Annual rings are the age of the tree. Every year it grows, an additional annual ring will appear in the trunk.

Bai Xuemei tilted her head and thought for a while, and after figuring out what Han Cheng was saying, she began to squat on the ground for a few laps with interest.

"One year, two years, ... eight years, brother, this tree is eight years old!"

After Bai Xuemei counted the circles, she shouted excitedly at Han Cheng.

The little child bride-in-law who discovered the novelty was so happy that she ran around and counted the lame-cut wooden rollers lying around.

"Brother Cheng, this tree is ten years old... this one is nine years old..."

The chuckle and joyful reports sounded continuously, surrounding Han Cheng.

Embracing the stone of flying dreams, after teaching the primitive bone tribe to learn a few words in Mandarin, they also gathered around to watch the lame use iron tools to make utensils.

Not only him, but the other members of the Qingque tribe, they like to get here when they are all right.

Many people even look forward to the lameness who is doing work and take a short break, so that they have the opportunity to touch the iron tools.

The teaching of the original bone tribe has now begun to differentiate.

Just like the people of the Qingque tribe taught by Han Cheng before, after the adults have mastered some characters, they start to let them choose for themselves. Those who want to learn the characters can continue to learn, and those who don’t like to learn the words of God can stop learning. Learning the words of God is no longer a rigid indicator.

For the promotion and popularization of Mandarin, no discount is allowed.

These are all aimed at adults. Minors who don’t need to work all day are still doing nearly three hours of study every day as before.

Bai Xuemei did not learn with them. As the child bride-in-law whom Han Cheng had approved, she had been eating Han Cheng's small stove.

I don't know if it is because of men's possessiveness. Han Cheng is unwilling to have too much contact with other men, especially if she is about the same age as her.

Eating and living with the son of God, although Han Cheng has never said clearly to the people of the tribe, under the subtle influence, the people of the Qingque tribe treat Bai Xuemei differently from others.

At the beginning, Xing, Xiaomei, Xiaoli and other people who were about the same age who wanted to sleep with the son of God were still a little dissatisfied with this, but now they are all used to it.

For primitive people, things similar to love ~www.wuxiaspot.com~ that are still in a state of ignorance will not occupy too much of their lives, especially those tribes who work hard for food all day.

Love in childhood is more like a storm in summer. It comes fast and goes fast. After some unpleasantness, Xing, Xiaomei, and Xiaoli basically no longer think about things that sleep with the son of God. .

The stone squatted on the ground and touched it with his hand. The sawn and flat section of the wood was lamely cut. His thoughts were flying fiercely, and his eyes were filled with joy and impulse of sudden enlightenment.

He has a keen interest in astronomical calendars, and he has always struggled with how old he is.

Because the calendar had not yet appeared when he was born, there was no way to know the specific age.

This is also an important reason for most tribes to determine whether they are adults based on their height.

Regarding how old he was, he thought about it for a long time, but there was no solution, but now, he suddenly had a clear understanding.

After the tree is cut with a saw, you can determine how old it is based on the circles in its body. Is this also possible for people?

Will it hurt too much if this is the case?

Thinking of this, then suddenly regretted.

People who were killed when they came to attack their own tribe should not be burned directly with fire. First cut open to see if there are some small circles on their legs. How good...

"Stone, what do you think?"

When Han Cheng saw Shishi squatting there without saying a word, he asked.

Shishi was stunned for a moment, and then told Han Cheng what he had just thought.

After Han Cheng heard it, his brain was full of circles, and there was an urge to retreat.

The former has witch-breed rabbits, and now there is a stone that wants to cut off the legs of people to test their age...Should you be so crazy?
