Chapter 392: Turning Stone into Gold
When it comes to metal smelting, Yin Se is naturally not a professional.

After all, hearing is believing, seeing is believing.

Qingyun followed Junior Sister Yin through several layers of valleys and came to a sunny valley.

Because it has been exposed to the sun for a long time, there is little moisture left here, the vegetation is sparse, and most of the mountains are bare rocks.

But the scene in front of my eyes is full of clouds and rosy clouds, and the middle of the mountain is wrapped in thick fog. From a long distance, I can smell a pungent smell.

That kind of mist does not conform to the laws of nature, and the smell is also unusual.

Qingyun probably already guessed that it should be written by Huayang's master and apprentice.

Liu Ying knew that the two of them were coming, and had been waiting by the side of the road for a long time.

With a mole nose mask on his face, Qingyun could only vaguely recognize the third brother by his figure and attire.

"Quick, put it on!" Liu Ying handed over two masks.

Qingyun had seen the world, so he put on the labor protection device very consciously, and followed Liu Ying down the valley.

"Fifth brother is here too!", the masked Douzhi saw Qingyun from a distance and greeted him.

"Why is this valley full of fog?" Asking if you don't understand is Qingyun's excellent quality.

"Oh, this is caused by the device for purifying Japanese lead. The teacher has been studying how to purify different kinds of lead."

"Are there still so many types of lead?" Although Qing Yun had heard Yin Seke's explanation, that little girl only knew how to throw out one term after another that he might not understand very well, and couldn't explain the point at all. .

I can listen to the personal explanation of the samadhi, and the samadhi is naturally different.

"The way of lead and mercury is the root of Taoist alchemy. Lead is mixed with gold. In fact, the ancients began to use the characteristics of different lead to improve the performance of hardware. The most common is copper with different characteristics. Copper and tin are smelted into bronze. , smelted with Japanese lead (zinc) to make brass, and smelted with Guifa lead (nickel) to make white copper, all of which are materials we often use."

"Then why didn't the ancients purify and distinguish various types of lead?"

"Although there are many types of lead, there are not many that can be used alone to make utensils. For example, the Japanese lead and ghost hair lead we separated are not as hard as iron, and their ductility is not as good as copper. However, they are more difficult to smelt. It is much more than the hardware we commonly use, and the mineral division is also limited. For example, ghost hair lead, although it was mined in the generation of Zhu Ti, it was smelted with copper to replace silver. However, if you want to purify, you can only use ghosts from Hexi. There is no other way to make ore. Therefore, the research on lead has always been limited to alchemy, trying to use the different properties of lead to change substances. For example, the famous alchemy is to use the properties of lead to complete of."

"Turn a stone into gold! Is there really such a thaumaturgy as turning a stone into gold?" Qingyun's voice was distorted with excitement. If his face was not covered by a mask, his expression at this time must be very exciting.This was not because he was obsessed with money, but because he suddenly heard that the legendary magical arts actually existed, and his curiosity was generated by spontaneous psychological stress.

"Since ancient times, alchemy has been open, and it is not a secret. It is clearly stated in the "Materia Medica": empty green, sweet and cold. It grows valleys. Bright eyes, long-term use makes light of body and prolongs life. It can transform copper and lead For gold. Born in Yizhou. Kong Qingshi can be used to refine gold, and the Chen mine that enlightens Kong Qingshi is sphalerite. There are not only real lead in sphalerite, but also Japanese lead. Kong Qing can be used to refine copper. Kong Qing Refined together with flash lead, you can get brass with a color like gold. This is the "turning lead and copper into gold" mentioned in the "Materia Medica", which is what the layman calls turning a stone into gold."

"If Taoism has this method, wouldn't it mean that it will become a battle of gold every day?" Uncle Chen once said to Qingyun when he talked about Confucianism that it is absolutely impossible to turn a stone into gold, because if gold is easy to get, the price of gold will be cheap. The monetary system based on gold and silver will be greatly impacted.

Unexpectedly, after hearing Qingyun's question, Tiezhi just casually said, "There is a technique, but it may not be practical. First, what the stone-turning-alchemy technique points out is not real gold, but real brass." Second, Kongqing is known as the ultimate stone medicine, and the price is not much lower than real gold. Coupled with a series of refining costs, this method of refining fake gold is completely worth the candle. The daily investment of gold is far more than that of gold ,is this necessary?"

With such an explanation, Qingyun suddenly realized that it was indeed because he had become a small person in the past.

The so-called turning stone into gold, stone is not necessarily cheaper than gold!

However, some unscrupulous Taoist priests used this as a selling point, pretending to be gods and ghosts, bewitching the emperor's family, and defrauding "research and development" funds with great profits as bait.This is the IQ tax levied by the alchemists who have mastered the relevant alchemy knowledge from the ignorant superiors.However, after being disseminated by the royal family, many deceptions using this as a gimmick have been formed among the people.

In fact, the essence is that the truth is only in the hands of a few people, and public opinion can only spread rumors and demonize alchemy.How many people still remember the first principle taught in Dan Ding's classic "Zhou Yi Can Tong Qi" is: to nourish oneself within, to be quiet and empty.Rest in movement and stillness, often with others?

And most of those charlatans who are full of mysteries have never even read these classics of the Dan family.

"By the way, you came today just in time. Help us fill the boiler together, otherwise the fog here may hurt passers-by who don't know." At the moment, he pulled them into strong men.

Qingyun also readily agreed, but on the way, he would inevitably throw out a hundred thousand whys, "What? To fill up the lead pit? Did the arrow shaft of the divine crossbow fall?"

"Huh? Your news is very well-informed. We just selected the materials, and haven't started manual purification yet. Whether it will be successful or not is still unknown."

"It hasn't been purified yet? Are those magic hair lead, Japanese lead, etc. all okay?"

Ji Zhi shook his head helplessly, "No. In order to pursue the ultimate accuracy, the arrow shaft must be made of metal, and wood with uneven density and difficult to control the shape of the device cannot be used. Moreover, the arrow shaft must be light and hard. The magic hair Lead and Japanese lead are not hard enough, and they are not light enough, so they are not good materials for arrow shafts. But after exploring the secrets of Yin Ruins, I suddenly got some inspiration, and talked with the teacher about the possibility of using thunderbolt, and wanted to try to restore the legendary Thunder lead is used to make arrow shafts. It is said that thunder lead mixed with copper is hard and light, but its preparation method is a secret that has not been handed down in the past dynasties. Good lightning-guiding materials are necessary for lightning techniques. The master refined some some time ago, and they are just in use."

Qingyun couldn't stop clicking his tongue, "Xuanyuan Five Stone Method, it sounds like those alchemists invented the name under the guise of Yanhuang. Who can prove that these methods once existed?"

"Who said it didn't exist? It is said that the ancient emperor cast the Xuanyuan sword and tempered it with this method. The power of Xuanyuan is unmatched in the world. Because there is no real thing, I don't believe it. But Goujian, the king of Yue, accidentally obtained this method and tempered a sword to set the foundation. The First Emperor corrected Zhengshuo, and also recruited the underworld warriors to replicate this method to harden the Qin Tongjian. The reliability of the latter two weapons is very high."
