When it comes to metal smelting, Yin Seke is naturally not a professional.

After all, what you hear is false and what you see is true.

Qingyun followed Junior Sister Yin through several levels of mountain cols and came to a sunny valley.

Because it has been exposed to the sun for a long time, little moisture can be retained here, vegetation is sparse, and the mountains are mostly exposed rocks.

However, the scene in front of me was full of steaming clouds and rosy clouds. Half of the mountain was wrapped in thick fog, and a pungent smell could be smelled from a long distance away.

That kind of mist did not conform to the laws of nature, and the smell was also unusual. Qingyun had probably guessed that it was the work of Master and Disciple Huayang.

Liu Ying knew that the two men were coming and had been waiting by the roadside for a long time.

There was a mole-nosed mask on his face, and Qingyun could only vaguely identify his third brother through his figure and clothing.

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

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

"The fifth brother is here too!" Xuan Zhi, who was wearing a mask, saw Qing Yun from a distance and greeted him.

"Why is there so much fog in this valley?" Qingyun asked in confusion.

"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 kinds of lead?" Although Qingyun had heard Yin Seke's explanation, the little girl only used one term after another that she might not even understand, and she couldn't get to the point at all.

.

If you can listen to Xunzhi's personal explanation, the Samadhi will naturally be different.

"The method of lead and mercury is the foundation of Taoist alchemy. Lead is mixed with gold. In fact, the ancients began to use the properties of different lead to improve the performance of hardware very early. The most common one is copper with different properties. Copper and tin are combined to make bronze.

, it is smelted with Japanese lead (zinc) to become brass, and it is smelted with ghost lead (nickel) to become white copper, which are all materials we often use."

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

"Although there are many types of lead, not many can be used alone to make tools. For example, the Japanese lead and ghost lead we have isolated 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 also has limitations. For example, ghost lead, although it was early in Zhu Ti's generation

White copper is mined and smelted together with copper to replace silver. But if you want to purify it, you can only use Guifa Mine in Hexi. There is no other company. Therefore, the research on lead has been limited to alchemy, and attempts to use various lead

The different properties of lead can change substances. For example, the famous Midas touch is accomplished by using the properties of lead."

"Turn stone into gold! Is it true that there is such a magic trick as turning stone into gold?" Qingyun's voice was so excited that he was a little distorted. If his face was not covered by the mask, his expression at this time would have been very wonderful. This is not because

He was obsessed with money, but he suddenly heard that the legendary magic actually existed, and his curiosity arose from spontaneous psychological stress.

"Since ancient times, the Midas touch has been open to the public, and it is not a secret. The "Compendium of Materia Medica" clearly states: The sky is green, the taste is sweet and cold. It is born in the valley. It improves eyesight. Long-term use can lighten the body and prolong life. It can transform copper and lead.

Make gold. Born in Yizhou. The empty bluestone can be used to make gold, and the empty bluestone can be used for enlightenment.

The Chen ore is sphalerite. There are not only true lead but also Japanese lead in the sphalerite. Kongqing can be used to smelt copper. Kongqing and flash lead can be smelted together to obtain brass with a color like gold. This is the "Compendium of Materia Medica"

The 'turning lead and copper into gold' mentioned in the Sutra is what lay people call turning stone into gold."

"If Taoists had this method, wouldn't they be fighting for gold every day?" Uncle Chen once told Qingyun when he was talking about Confucianism. It is absolutely impossible to have the Midas touch, because if gold is easy to obtain, the price of gold will be cheap. In the Central Plains, it is

The monetary system based on gold and silver will be greatly impacted.

Unexpectedly, when Xunzhi heard Qingyun raise this question, he just casually said, "There is a technique, but it may not be practical. First, the Midas touch is not real gold, but gold-like brass.

Secondly, Kongqing is known as the best stone medicine, and its price is not much lower than that of real gold. Coupled with a series of refining costs, refining fake gold in this way is completely outweighing the gains. Every day there is a lot of gold, but the daily market is far more than a dollar.

Jin, is this necessary?"

With this explanation, Qingyun suddenly realized that it seemed that his situation was indeed small in the past.

As the saying goes, turning stone into gold, stone may not be 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 using heavy profits as bait to defraud "research and development" funds. This is an IQ tax levied by alchemists who have mastered the relevant knowledge of alchemy from the ignorant superiors. But

After being spread by the royal family, many deceptions using this as a gimmick were formed among the people.

In fact, the essence of it is that the truth was only in the hands of a few people at that time, and public opinion could only spread lies and demonize alchemy. How many people still remember that the alchemy classic "Zhou Yi Shen Tong Qi" first taught to nourish oneself internally,

Quiet and nothingness. Rest in peace and quiet, often with others?

And most of those charlatans and charlatans who talk all kinds of mystical things have never even read these alchemy classics thoroughly.

"By the way, you came just in time today. Help us fill up the boiler, otherwise the fog here may hurt unsuspecting passers-by." Xuan temporarily pulled them into a strong man.

Qingyun agreed readily, but on the way, he would inevitably have to ask a hundred thousand questions, "What? Do you want to fill up the lead pit? Is the arrow shaft of the divine crossbow missing?"

"Huh? Your information is very good. We have only selected the materials and have not yet purified them. Whether it will be successful or not is still unknown."

"It hasn't been purified yet? Aren't those magic hair lead, Japanese lead, etc. not acceptable?"

Xunzhi shook his head helplessly, "No. In order to pursue the ultimate accuracy of crossbow arrows, the arrow shaft must be made of metal, and wood with uneven density and difficult to control the shape of the tool cannot be used. Moreover, the arrow shaft must be light and hard. Magic Hair

Lead and Japanese lead are not hard enough and light enough, so they are not good materials for making arrow shafts. But after exploring the Yin Ruins, I suddenly felt

For some inspiration, I talked with my teacher about the possibility of using thunderbolts, and wanted to try to restore the legendary thunder lead to make arrow shafts. It is said that thunder lead is mixed with copper, making it hard and light, but the method of preparation is a secret that has not been passed down from generation to generation.

The Xuanyuan Five Stone Forging Technique is also a lightning magic technique that was lost in ancient times. Japanese lead is a very good mine-conducting material, and the master refined some of it some time ago, and it just comes in handy."

Qingyun kept clicking his tongue as he listened, "The Xuanyuan Five Stone Method sounds like a name made up by those alchemists under the guise of Yanhuang. Who can prove that these methods have ever existed?"

"Who says it never existed? Legend has it that the ancient emperors forged the Xuanyuan Sword and tempered the sword with this method. The power of Xuanyuan was unparalleled in the world. Because there is no real object, just listen to it and don't believe it. But King Goujian of Yue accidentally found this method and tempered a sword to set the foundation.
