By this point, the women had roughly understood the great usefulness of metal, and in their excitement, according to what Ah said, they kept placing stones next to metal.

Zhang Jingtao also helped.

When everything is done, Ah He said: "We have to study this hole carefully, and then, seal it again, because the state in this cave can tell us how these stone gold came from, these stone gold usually can't be burned, it must be at an extremely high temperature, and after we burn the stone gold ourselves, these stone gold will be of great use." ”

"Uh-huh." Chu Nu's face flushed with excitement, because she knew that Ah He had wanted to cook chicken soup to drink, but there was never a good way, wouldn't this unburnable stone gold be very useful?

It's just that, in addition to agreeing, Chu Nu couldn't help but ask worriedly: "What if this cave mansion is destroyed because of oil-eating people?" ”

Ah Ha smiled: "It doesn't matter, more importantly, we know how Shijin came from." We also know how big the furnace must be, how much material to put in order to be able to burn stone gold, and I also know that salt, alkali, earth and other things can be burned together with stone gold, and different stone gold can be burned, if this hole is destroyed, we will find all kinds of stones and burn a new furnace. ”

Chu Nu thought about it for a while, and asked happily: "What words do we use to express the fire that came out of the cross?" ”

Ah Yu immediately had a strong interest, and drew a big word 'fire' on the open space on the side, and said: "Point, can have the meaning of light and shadow, appendages, seals, etc., the word I wrote, is fire, it has the meaning of the staggered friction of the word 乂, because I think that not only bamboo, but also many things as long as they rub hard enough, should also be able to catch fire, and break it on the left side of the word 乂, and become a point, that is, this point, is the bamboo body of the appendage bamboo chips and bamboo leaves, so that the fire can be lit, and, After the fire ignites the wooden pile, this point really becomes an appendage of light and shadow, and as long as the fire has various fuels, it can spread like the word 'human', so I plan to add a conspicuous herringbone structure, so that the word 'fire' is born. ”

Zhang Jingtao suddenly felt his soul shake, because this involved the point in the word 'Xi' that he wrote on Guanyin's body with his mind.

Fortunately, it was just a shaking, and it didn't leave his soul.

For this reason, Zhang Jingtao even felt very strange, you know, the meaning of light and shadow, heat, appendages, and seals contained in ' is already relatively comprehensive, but it doesn't touch the karmic support, can this'' have other meanings?

Zhang Jingtao couldn't figure it out.

And after Ah He's memories and discrimination, the silk girls are very clear about Shi Jin's arrangement of stones.

In particular, the ores in the corner of the cave are large and small, and the stones of the same color are piled together, and they are all stones that Ah got at the same time period, that is to say, they were originally placed in a certain order, and the stones that Ah Ah piled up next to the fire are also in the same order.

After looking at these classified stones, Ah said, "Huh? It seems that the color of copper will change, because it is mixed with different other stones, probably because it is integrated with leadstone, zinc stone, and cassiterite. ”

Of course, this way of speaking is just Zhang Jingtao's explanation in his heart, otherwise, he would have to use ape-man gestures to illustrate these strange metals, and of course he hasn't named these metals yet.

There is only steel, Ah Ah doesn't understand why the raw materials are the same, but the black is translucent and white, which will be very different from the iron of black Qiqi.

In Zhang Jingtao's mind, it is difficult for Ah to figure this out.

But he couldn't hold back his voice, and it didn't affect Ah Ah's thinking, but he always thought about whether to push Ah Ah when he didn't understand.

After all, Ah Ah has completely understood how to smelt, so his inference will only speed up the process of human civilization at most, but it will not affect Ah Ah's creativity.

You must know that Zhang Jingtao has always been afraid that his thinking will interfere with Ah He's spirituality, and he doesn't care whether the process of human civilization will speed up.

Unexpectedly, after careful observation, Ah also figured it out, she grabbed some toner, twisted it and said, "Huh? This metal, like a human, eats, but it is afraid that it eats this charcoal, or it breathes in the toner, and for this reason, it is no different from the raw material of iron, but it becomes steel. ”

Undoubtedly, steel will have such a magical glyph, which is roughly the opposite of fierce, that is, steel, breathing downwards and absorbing what is below, and what is underneath? Obviously, for the steel underneath is the flame, and only the carbon that comes out of the flame burns out.

As for saying downward, it can be seen from the glyph of fierce that fierce, with the mouth facing upwards, is a human being breathing upright, just like a zone, which has the meaning of zone pressure, so that a person exhales to the side, and Gang, naturally, breathes downward.

Of course, at the same time, this uses the gang character of the Zhou character frame, and then there must be a round of overlapping hammering tempering meaning.

Because the frame of the word Zhou must be able to represent the meaning of the surroundings, the circumference, and the repetition of the wheel.

Zhang Jingtao wanted to scream from the moment he entered the cave, and at this moment he finally could, and immediately shouted happily: "Ah! Yes! Yes! Ah, that's amazing! ”

Ah He smiled dazzlingly, and saw that the steel piece was very sharp in one place because of its shape, so he took the steel piece and scratched it on the leaves, and stabbed it into the wood hard.

After this experiment, Ah He was even happier, and said: "What a powerful stone gold, tomorrow we will go to find the stone, and we will also open a big fire hole on the island to burn the stone, not only to make the stone gold bamboo tube, but also to make the stone gold arrowhead, instead of the stone arrow!" ”

Chu Nu also felt that this must be very remarkable, so she asked, "What is this arrow called?" ”

Ah He looked at the dagger in her hand, and the crescent moon shape was like the character in the seven characters she created, and said, "This arrow, let's call it a sword." ”

Ah said that the word "乚" is used in the sound of "yi", because although this thing represents a curved object and the tail of a wealth dog, the main original meaning is still to represent the movement of light, so it still uses the "yi" sound with the meaning of moving.

Then he went to look closely at the condensed mud, and in detail he could tell that it was from the kind of stone that was burned.

There is very little natural marl, which is formed by the limestone bursting some powder mixed with the burned clay, and most of the limestone is only burned into a lump of mixture with the soil.

Ah Ah took a piece, smashed it, and then crushed it with a stone a few times, and saw exactly the same plaster.

Chu Nu saw that there was a piece of limestone that was burned out of the limestone, but there was still black ash on it, and the place where the cave was originally burning and hooking the fire, because she had dug a pit, accumulated the rainwater accumulated during the heavy rain in the past two days, and it did not all evaporate, she did not know the danger of this stone, so she took the stone to wash.
