His lame eyes were shining, and he couldn't stop circling around the wooden ladder made by Han Cheng.

While turning in circles, he also touched the wooden ladder from time to time, and sometimes held one end of the wooden ladder, and after lifting it, he shook it vigorously.

The wooden ladder is still sturdy, and there is no meaning of loosening.

The more this happens, the brighter the lame eye becomes, because he has found a whole new direction!

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

But now, Miko has actually made an incomparably strong wooden ladder that can be connected without being tied with a rope!

This is no worse for a lame who is obsessed with all kinds of handicrafts than the night after adulthood, poking the door to a new world!

"Miko!"

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

This was the way the Qingque tribe showed respect for Han Cheng, and even the highly respected witches rarely received such courtesy.

Wu was also looking at the wooden ladder, and in his opinion, the wooden ladder made by the Son of God was indeed more exquisite, better than the kind that was tied up with rope, but it was not so good as to be ecstatic.

Lameness is not to get excited, so it's right.

This is the cognitive bias brought about by different occupations.

Just like the clay plate that Wu was pleased with and used to engrave words, in the eyes of the lame, it was actually nothing more than that......

There is a fanatical handicraft enthusiast with lameness, and the rest of the wooden ladder manufacturing, Han Cheng basically doesn't interfere and lets lame do it.

Only if some lame people don't understand something, he will guide it.

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

Because with the manufacture of more and more things, the production of various objects must also meet certain standards, so that the manufactured things are more beautiful, and the other is to do it in accordance with a certain standard, and the things on the object are damaged and easy to replace, so that there will be no part on the object is broken, and the whole will be scrapped.

Of course, there is also the fact that Han Cheng wants a relatively accurate measurement tool.

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

First estimate the length of a ten-centimeter, and then use the length of the ten-centimeter as the standard, step by step to extend a ruler of one meter, one meter five or even two and a half meters.

Then, within this standard ten centimeters, evenly carve out a scale of zero to ten, mark it with numbers, and after carving, make a little charcoal foam on your hand, and then rub it with your hand on these scales, and the scales that are not very obvious will immediately become clear.

Again, this is a standard ten-centimeter stick, and the scales on the other sticks of different lengths are accurate to centimeters, and in the middle of each centimeter, a small vertical bar is engraved, which is a half-centimeter mark.

For the current Qingque tribe, the accuracy to the centimeter is enough to use.

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

Therefore, for the original ten-centimeter wooden segment, Han Cheng was very attentive to preservation.

After communicating with Wu for a while, and explaining the importance of this thing, Wu Wu, who seemed to understand it or not, placed it on the stone slab in front of the totem pole with a feather crown and a bone staff, which was the most sacred place and the safest place in the entire Qingque tribe.

Wu didn't fully understand Shenzi's words, and he didn't know how this small section of ordinary wooden stick could suddenly become so important.

But since the Son of God said it so solemnly, it must not be wrong.

The manufacture of the ruler is a meticulous work, and it cannot be sloppy at all, in order to do these things well, Han Cheng did it for seven or eight days one after another before it was completed.

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

Thus, the tape measure was born.

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

Han Cheng intercepted two ropes, one rope was ten meters and one rope was five meters, both of which were measured with the previous ruler.

Then start from the beginning, every ten centimeters, a single rope grass is used to tie a small pimple here, and a meter is twisted into a thin rope with two rope grasses, and a large pimple is tied, so that the problem of leaving a scale on the rope is perfectly solved.

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

The finished 'tape measure' is wound around a short wooden stick, pulled apart when it is used, and then wound around it 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 a lot of effort and spent a lot of tongues to let them gradually accept and understand what a ruler is and learn how to use it.

In terms of the comprehension and use of rulers, the fastest learner is not Shishi, who is extremely talented in Chinese and Chinese characters, but this guy who is lame.

This may have something to do with the fact that he has been weaving a series of things such as fish cages, wooden rafts, and grids for more than a year.

Because these things have to be made to a certain size, he has been exposed to more, and it is naturally faster to understand and use than ordinary people.

followed by Heiwa, the first potter of the Qingque tribe, and then the stone.

Among these people in the tribe, Han Cheng admired the lame one more.

Because he had suffered a 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 it and didn't let go.

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

The lame holds a piece of charcoal in one hand and a one-meter-long ruler in the other, and makes a gesture on a wooden pillar that is flat on the ground, muttering something quietly in his mouth.

It looks a bit like a later carpenter.

He's looking for a spot to figure out.

If you want to make a wooden ladder out, the holes used to thread the horizontal bars on the pillars on both sides of the ladder must be aligned, otherwise, the horizontal bars will either not fit in or loosely ......

He did things selflessly, not noticing the approving look in the eyes of Han Cheng who was standing aside.

(Good news!) Good news! I received the news that I would go to Sanjiang at 2 o'clock this Sunday afternoon, and I was so excited that I finally got the recommendation that I had been looking forward to for so long!

Thank you for your support. I am also very grateful to my editorial boss for giving me such an important push and pull position for such a niche book. Thank you.

Tomorrow the old book will end, you can concentrate on writing a book, from the day after tomorrow every day is a double update, save some manuscripts waiting to be put on the shelves. After it is put on the shelves, the update will not be so weak, and it will break out from time to time.

And then...... It's better to ask for a ticket, comrades have a ticket in their hands, just greet me to your heart's content! Not afraid of pain.
