After three rounds, there was no one left to stand.

The rain of arrows swept back to the surface of the water.

Only screams remained on the surface of the water, staining the clear surface of the lake with blood flowers.

Annihilation!

Tomahawk thought about this word before he died, and his heart was full of regret.

Mend the knife!

When the warriors of the Silk Clan were in the White Bone Clan, they fought a lot, and they would not be soft in the slightest.

After the battle, in addition to cheers, Zhang Jingtao was thrown up by several men to celebrate, and the silk people naturally wanted to take back all the long arrows.

In this battle, no enemy could escape, and the arrows were everywhere.

Even if this arrow fell into the hands of the oil-eater, it did not matter much, and without a longbow, the arrow was at most like a sharp knife.

Even the arrows in the lake were fished back by Zhang Jingtao.

After all, the silk clan is still very scarce for the time being.

The rainbow forged with Ah Xue said that all the resources known to the five-color clan, and to Zhang Jingtao's expectation, the five-color clan still knew quite a lot of minerals, but unfortunately, these minerals were quite far away from Xidao.

It takes the power of the barbarian to transport the ore to the silk clan, which takes time.

It is not surprising that this will be the case, the range of activities of the five-color clan in the past will not be too close to the north.

After the battle, Zhang Jingtao couldn't hold back any longer, thinking that if he looked at the smelting, he wouldn't alarm Xizi, so he went to Ah's metal production studio.

He was busy impregnating the women, training them in archery formations, and even teaching them how to swim on the shore in advance so that they could learn to swim in the summer.

Before arriving at the shed, Zhang Jingtao was surprised to see a child playing 'No Waves'.

There is no drum, the top is a small drum, and the bottom is vertically installed with a wooden trunk, and then at the junction of the small drum and the wooden trunk, two ropes are installed, and the top of the rope is equipped with any beads as a bone hammer.

The drum noodles are made of bamboo and sheepskin.

When such a drum is shaken, it becomes a 'no' shape.

If you use more force, the bone hammer will hit the drum surface in the swing.

No, that's how it came about.

It's a lot of fun.

For this, shaking the head can mean no.

And Ah made this toy to let children understand what a circle is.

It is these two ropes that are thrown together to form a circle.

For this reason, Ah Ah has come up with a compass, and this kind of compass, Ah Ah calls it 'also'.

Also, this character is the hand-held stem of the compass in the middle, one end is the center Ding, the other end is drawn a circle, the center Ding rotates in reverse in situ, and the circle is rotated in reverse around the center Ding, and you can draw a circle like the 'earth' ball.

For this reason, half of the word "earth" is used in the word 'also'.

It's just that the earth is a big ball formed by the 'earth' rotating in the opposite direction.

Confucianism would use the word 'also' at the end of sentences, because the earliest Confucians, at least roughly aware, that the word 'also' can represent a circle, which can mean a full stop, just like the word 'xi' made by Confucianism can represent a broken comma.

This is why some literati are under the high pressure of Confucianism, and they are unable to resist, but they still have a conscience, so they will write some metaphors and hide them in the text for future generations to ponder, such as Qu Yuan's "Tianwen", "Lisao", and so on.

Of course, the cognition of these literati is often only a little groping, and it is not necessarily accurate. And they are exhausted, and they are only circling in circles among the things that the Confucians have made, in order to never get around such a labyrinth.

And the reason why the word 'also' can mean multiple selectivity, can be this or that, is precisely because it is the embodiment of the compass.

It can be reversed, or it can be reversed, and it can all achieve the same purpose, drawing a circle.

Its span can be enlarged or smaller, and it can still draw a circle, at most the size of the circle is different.

And the compass, in the 21st century, is still recognized as coming from China, but it has not yet come up with a foreign theory.

For this reason, Zhang Jingtao finally had a sudden understanding of the word 'pool' in the pool involved in He's Bi.

Depend on! It turns out that it is a completely round pool.

As for the three points of water, it is undoubtedly the meaning of the water gathering in one place to become a pool, and the strokes in the three points of water are usually reversed, or reversed, and rotated into a circle.

This is the case next to the soil word, the same is true next to the handle, and the same is true for the three points of water.

No wonder there is information about He's Bi in Xiangtang Villa, that Tai Chi Pool, is it a pure round pool?

and not drumming, but also made Zhang Jingtao understand why Ah He would understand that the speed of light can be measured with gears.

There is no doubt that Ah, who is good at observing shadows, finds that the shadow when the drum does not rotate, has the effect of blocking light, as long as the drum does not shake fast enough, Ah He thinks that the two rocker arms can overlap and block the light, and the speed of the non-wave drum that blocks the light is the speed of light.

Referring to this principle, Ah He, who knew how to draw a circle, thought of adding a vertical stem to the circle, that is, making the disc into a gear to test the speed of light, in this way, the gear can be made very large, as long as the rotation speed of the gear and the number of teeth are calculated, it is easier to measure the speed of light.

Of course, Ah didn't do such an experiment, it was just her inference.

She thought there was no problem with this inference, and for this reason, she created the word 'light', and the word 'light' has a method for measuring the speed of light.

For this reason, Zhang Jingtao also found that Ah Hao had already had the idea of calculating circles.

For some reason, Ah has an accurate length unit datum.

Otherwise, the recent arrowhead production will not be so smooth, in the past, although Ah would use her thumb as a size reference, but still can't make a large number of things with a very standard size.

When I arrived outside the shed, I saw that Sister Watermelon was using a wooden board mold with a very standardized size to press the bricks, and the wooden lattice of the pressed bricks had the word 'mother' written on it.

This kind of plank is made with some cutting tools and a hacksaw.

But it's this tooth and saw, and Auntie, who knows how to rub bamboo to start a fire, knows this very well.

The scratch is very narrow, the tighter the friction between the edge of the friction bamboo and the cut of the bamboo, the greater the friction, the easier it is to catch fire, if the cut of the bamboo becomes larger, the friction will become worse, but it is easier to cut off the bamboo.

As for the story of Lu Ban, it is said that the saws were invented after the thatch was strained?

It can only be a story that foreigners or Confucians who have no civilization and no common sense of life.

In this story, I didn't even understand the principle of the saw!

For this reason, if you don't want the processed bamboo to be scorched by friction and the scratch hole expands, it is best to let the friction-dry peak sway from side to side like a wave.
