I am a Primitive Man

His lame eyes were shining, and he kept turning around the wooden ladder made by Han Cheng.

While circling around, he would touch the wooden ladder from time to time, and sometimes he would hold one end of the wooden ladder, and after lifting it, shake it vigorously.

The wooden ladder is still strong, and it doesn't mean to be loose at all.

The more this is the case, the brighter the eyes of the lame, because he has found a new direction!

In the past, if he wanted to connect two things together, the only way he knew was to tie them with a rope, or a rattan that could be used as a rope.

But now, Shenzi actually made an extremely strong wooden ladder that can be connected without ropes!

For a lame who is obsessed with various handicrafts, it is no worse than the night after adulthood, when he opened the door to a new world!

Son of God!

The more he thought about it, the more excited he became, he let go of the wooden ladder and saluted Han Cheng, shouting respectfully.

This is the Qingque tribe's way of showing respect to Han Cheng, and even the highly respected Wu rarely receives such courtesy.

Wu was also looking at the wooden ladder. In his opinion, the wooden ladder made by Shenzi was indeed more exquisite, better than the one tied with ropes, but it was not so good as to make people ecstatic.

It's right to be lame without being excited.

This is the cognitive bias brought about by different occupations.

Just like the pottery board used to engrave characters that the witch was delighted with, it is actually nothing more than that in the eyes of the lame...

With Lai, an enthusiastic handicraft enthusiast, Han Cheng basically didn't get involved in the rest of the wooden ladder manufacturing, and let Lai do it.

Only when there are some lame people who don't understand, he will give guidance.

It is worth mentioning that Han Cheng has already got the ruler out.

Because as more and more things are manufactured, the production of various objects must meet certain standards, so that the manufactured things are more beautiful, and the other is that they are all made according to certain standards, and the things on the objects are damaged. In order to be easy to replace, it will not happen that one part of the object is broken and the whole will be scrapped.

Of course, there is another one that Han Cheng wants a relatively accurate measurement tool.

This ruler is also simple to make, just find some straight wooden strips, peel off the outer skin, leaving only the white inner bone.

First estimate a length of ten centimeters, and then use this length of ten centimeters as a standard to gradually extend a ruler of one meter, one meter five, or even two and a half meters.

Then, within the standard ten centimeters, evenly engrave the scale from zero to ten, and mark it with numbers. After engraving, put a little charcoal foam on your hand, and rub these scales with your hands. No matter how obvious the scale is, it will become clear immediately.

Similarly, using this as a standard ten-centimeter stick for comparison, the scales on the other sticks of different lengths are all accurate to centimeters, and a small vertical bar is engraved in the middle of each centimeter. , that's the half centimeter mark.

For the current Qingque tribe, accuracy to the centimeter is sufficient.

Of course, the distance of ten centimeters estimated by Han Cheng will be more or less different from the ten centimeters of later generations, but there is no need to worry, as long as he can continue this standard and ensure that the rulers he manufactures later will be If they are all the same length as the original ten centimeters, then his standard is accurate.

Therefore, for the first ten centimeters of wood, Han Cheng was very careful.

After communicating with the witch for a while, and after talking about the importance of this thing, the witch who seemed to understand half understood put it on the stone slab in front of the totem pole where the feather crown and bone staff were placed, which is the most sacred place in the entire Qingque tribe. , is also the safest place.

Wu didn't fully understand Shenzi's words, he didn't know how this small section of ordinary wooden sticks suddenly became so important.

But since the Son of God said so solemnly,

Then it must be right.

The manufacture of rulers is a meticulous job, and there must be no sloppy work. In order to make these things well, Han Cheng worked one after another for seven or eight days before completing the work.

However, the ruler made of wooden sticks also has its disadvantages, that is, it is not long enough, and it is okay to measure shorter things, but once it is long, it is extremely inconvenient to use.

Thus, the tape measure came into being again.

The material of the tape measure is very simple, that is, the twisted rope.

Han Cheng intercepted two ropes, one ten meters long and the other five meters long, both of which were measured with the previous gauge.

Then start from the beginning, every ten centimeters, tie a small knot here with a single piece of rope grass, and tie a big knot with a thin rope made of double rope grass every one meter, so that it is a perfect solution Solved the problem of leaving scales on the rope.

These two 'tape measures' are basically used to measure the 'foundation' of the courtyard wall, the gap between the beams and other large distances. You don't need to be too accurate, and the scale of ten centimeters is enough.

The manufactured 'tape measures' are respectively wound on the short wooden sticks, pulled apart when in use, and wound on top when not in use.

In order to popularize the concept of rulers to the people in the tribe and teach them how to use them, Han Cheng also put in a lot of effort and spent a lot of talking and talking to let them gradually accept and understand what a ruler is and how to use it.

In terms of understanding and using rulers, the fastest learner is not Stone, who is extremely talented in Chinese and Chinese characters, but the guy who is lame.

This may be related to his frequent weaving of fish cages, wooden rafts, fences and a series of things in the past year or so.

Because these things must be made with a certain size, he has more contact with them, and naturally understands and uses them faster than ordinary people.

Next is Heiwa, the first pottery maker of the Qingque tribe, and then stone.

Among these people in the tribe, what Han Cheng admired most was lameness.

Because of his leg injury before, he had experienced the sadness of becoming a burden, so when Han Cheng's appearance brought him some hope, he desperately grabbed hold of it.

In this way, after more than a year, when he looks back, he will be surprised to find that he already has so much! And many of them are far beyond ordinary people.

Lame is holding a piece of charcoal in one hand and a one-meter-long ruler in the other, making gestures on top of a wooden post lying flat on the ground, murmuring something in a low voice, and making gestures like this for a while , and draw some imprints with black charcoal on the wooden pillars.

It looks a bit like a carpenter of later generations.

He is looking for the point where he needs to make a burrow.

If you want to make a wooden ladder, the mortise holes on the pillars on both sides of the ladder for passing the horizontal bar must be aligned, otherwise, the horizontal bar will either not fit in when the time comes, or it will be loose...

He was doing things selflessly, but he didn't notice the look of approval in the eyes of Han Cheng who was standing aside.
