In addition, on the ground in the fire cave, there are many small metal water-soluble gold cakes, silver cakes, copper cakes, zinc cakes, lead cakes, tin cakes, and iron cakes.

The zinc cake was about to fall down along a hole wall. Against a hole wall, the copper cake had several colors, which were derived from pure copper: bronze, brass, and white copper.

There are even the evolutionary products of discus, steel cakes, which are located in the middle of the hole.

Because there is absolutely no shortage of carbon components in this hole, and the temperature of this big hole must have increased amazingly at that time.

The temperature increase requires insulation space and time.

Not profound and complex.

The conditions for the Niu Mo Fire Cave are met.

The crescent-shaped dagger is made of molten steel.

After Ah He couldn't feel the temperature of these metals, he was surprised to pick up the crescent dagger and immediately felt the powerful strength.

This is not only the carbonized steel, but also the hardness of the surface is caused by rainwater entering the hole, which has a quenching effect.

Ah Yi, who was good at thinking, immediately discovered that these were all amazing things and did not rush to pick up all of them.

Ah Yi pointed to the naturally formed crescent mold and said, "This is the stone essence burned out of the stone. They are very hard and can be used as a tool for excavation. As long as we can make such molds and find stone essences that can produce stone essences, we must remember which stone essence comes from which stone essence."

After hearing this, Zhang Jingtao immediately discovered that he was proficient in golden sounds.

Undoubtedly, Ah Yi will give gold and use essence. The pronunciation is naturally the sound of "gold and gold" produced by metal collision. Although Ah Yi uses the meaning of essence to express metal, in fact, the sequence of these two words is reversed.

In terms of sequence, metal gold characters appeared earlier because Ah Yi had never created the word Jing before.

And at this moment, the golden characters will probably be created by Ah Yi soon.

Then, the initial essence actually uses the word "gold".

For this reason, China has the place name Jinhua, and many people do not understand its meaning. In fact, its original meaning is the meaning of "element".

Jinhua ham is a very famous food.

The girls who were talking in shock agreed, knowing that they should not touch these things randomly, but rather classifying stones and metals. When everyone remembers them later, they can find such stones in the wild to burn stone spirits.

The girls carefully packed up.

I heard Ah Yi say again: "Each stone spirit can only be taken away the same, and the surrounding stones are the same. Only if there is the same one can be picked up. If there is only one type, don't pick it up."

But Chu said, "But there are no stones beside some stones, so I'm afraid they'll burn them."

Ah Yi saw that there were many stones piled up by her in one corner of the cave, and there were very complete types. Because it was a corner of the cave, the stones were still intact, he said happily: "It doesn't matter, I'm watching the layout of the stones in this cave every day, all in my mind. I even remember that there was saline and alkali on the side of the fire. As I said, you picked up the stones over there and matched them with the metal over here."

The Chu girl agreed, and then listened to Ah Yi's instructions and became busy.

When Zhang Jingtao saw it, he just wanted to laugh.

The invention of metal smelting, which later generations believed to be extremely complex, was actually so simple.

This hardware was actually served by Ai in a pot because Ai likes to collect stones and makes a melting pot!

He had no doubt that even if he had not eaten oil, Ah Yi would have discovered this sooner or later, because Ah Yi had long understood that people needed sheep energy and burned sheep energy, and also knew the use of charcoal, and also created the cross-fire method, so he would not be afraid of the fire cave extinguishing.

Therefore, in order to save fuel, Ah He will definitely play the method of sealing the hole to reduce the input of sheep gas, but he does not know that the ventilation vent is still enough to enter the sheep gas, which will only create a high temperature in the entire cave. Then, once the dryness hidden in the hole is ignited due to the high temperature, such a fire will inevitably be triggered, thereby burning out metal.

Or, even if Ah Yi only burned metals with a lower melting point at the beginning, this discovery would inevitably lead her to gradually discover all the metals.

For this reason, Zhang Jingtao immediately discovered that in modern times, all humans who only know how to play with fireplaces could not invent metal manufacturing. Only Chinese people who are good at playing with earth pits, who understand the concept of cellars, can they have the ability to burn metal in ancient times.

Logic is the best evidence, this is cause and effect. Without cause, where does the result come from?

In China, you can find all the reasons: cause!

It seems that Ah Yi, who has become a "Huo Zheng", plans to change his career and become a "Da Zhurong" in the future.

In addition to being happy in his heart, Zhang Jingtao also walked to look at the metal carefully, and picked up one from time to time to take a look.

It turned out that these metals were really complete.

Even daily hardware is complete.

As for what is hardware?

Indeed, many people don’t know which hardware is in daily life, because there are far more than five types of metals, and they all seem to be very commonly used.

For this reason, many people say that the ownership of hardware should be: gold, silver, copper, iron, and tin;

Or: gold, silver, copper, lead, tin;

etc.

However, no matter what, almost all gold and silver are included. But the problem is that hardware should be the best metal used in daily life, so why should gold and silver be included?

Their application range is not wide, and it is definitely not a reason to be used daily. What hardware requires is that everyone can use it, and it is enough for daily use.

Fortunately, Zhang Jingtao knew that the real hardware was: silver, copper, gold, aluminum, and zinc.

For this reason, he was really surprised when he saw aluminum in the hole.

Can it burn aluminum?

Isn't it just obtained by electrolysis?

Zhang Jingtao was really surprised by this. After thinking about the smelting knowledge obtained from Luo Anguo, he realized that Luo Anguo also said that aluminum can be burned through alkali, salt, fluorite, alumina, and higher furnace temperatures.

These things are commonly used by Ai. There are many fluorites in the second part of Jiangsu and Zhejiang in later generations. The word alum in alumina is even more fake. Just use the ordinary word ordinary, which shows the popularity of ordinary land.

For this reason, aluminum is produced, not surprising.

However, during the process of burning aluminum, whether saline and alkali reacted with other minerals, he did not take a closer look at Luo Anguo's method of burning aluminum. After all, the craftsmen in the Warring States Period also knew those methods. At that time, Zhang Jingtao thought there was no need to remember all the details. Metal smelting will naturally be passed down by craftsmen, as long as China is immortal.

In short, aluminum will be placed inside because the definition of this hardware is based on conductivity.

In ancient China, the Silk people had long used electricity, and electricity was undoubtedly like a miracle. For this reason, metals with good conductivity were increased their importance.

The Gold and Silver Association belongs to hardware. It is precisely because of this situation that it also proves how early it is for China to use electricity.
