Alchemists have indeed made great achievements in smelting alloys and making medicines, and they used to produce yellow alloys and white alloys in batches. Among them www.biquge.info there are brass (zinc-copper alloy), cupronickel (nickel-copper alloy), arsenic cupronickel (arsenic-copper alloy), white tin silver (arsenic-tin alloy), and of course, various amalgams. This is the result of an alchemist. But after the Tang Dynasty, especially in the Yuan and Ming dynasties, it was used by some charlatans as a means of defrauding money. This kind of scam is well documented in old novels and notes. For example, in the fourteenth chapter of "The History of Confucianism", "Ma Xiucai Cave Meets Immortals", such a story is told: Mr. Ma Er, a social celebrity, passed by Dingxian Cave in Hangzhou and met an old man with a white beard over the navel and a fairy appearance, claiming to be surnamed Hong and Hanxian. Hong Hanxian said to Mr. Ma Er: "If you want to get rich, why don't you ask me!" So Mr. Ma Er accepted a few pieces of "black coal" given by Hong Hanxian and went back to smelt, and it was really smelted into silver. So Mr. Ma Er thought that he had met a living immortal this time, so he agreed to recognize Hong Hanxian as a cousin, and went to Hu Shangshu's third son's house with Hong Hanxian to testify for him, and asked Hu Sangongzi to contribute capital to "burn silver". Who knew that Hong Hanxian suddenly fell ill and died at this time, and his family told Mr. Ma Er that Hong Hanxian was not an immortal, but a liar, and that the "black coal" was originally blackened silver, giving Mr. Ma Er some benefits, so that he believed it was true, so as to help Hong Hanxian to commit perjury and defraud Hu Sangongzi's money. Mr. Ma Er felt embarrassed after learning the truth.

It's about the Ming Dynasty, and almost at the same time, there was a similar alchemical scam in Europe. The Renaissance English writer G. Chaucer (~1343-1400) told an alchemical deception in his "Canterbury Tales": in England, there was a priest who met a monk, and the monk asked the priest to prepare two or three taels of mercury, take one tael and put it in a jar and smelt it with charcoal, and pile the coals all the way to the top of the jar. While the priest was not looking, the monk took out a piece of charcoal from himself and placed it on the mouth of the jar, which had been dug in the center beforehand, and the hole was pre-filled with a tael of silver powder and sealed with wax. Of course, after this charcoal is burned on the mouth of the jar, the silver powder quickly falls into the jar, smelts with the mercury, and pours it into a mold to condense into a silver ingot. Then the monk performed again, and asked the priest to put another tael of mercury in the jar to smelt, and this time the monk took out a stick and stirred charcoal on the mouth of the jar, and it turned out that the head of the stick was also hollow, and it was filled with silver powder and sealed with wax. When the wax melted when the charcoal was stirred with a stick, the silver powder fell into the jar again, and another piece of silver was made. The monk asked the priest to take the smelted silver to the market and have it examined by a silversmith to prove that it was indeed real silver. At this time, the priest became even more convinced, so he spent a great deal of money to buy the secret recipe from the monk. The monk slipped away after getting his money, but the unfortunate priest tried to make money with the secret recipe but could not make anything, and ended up ruining his family.

It should be pointed out that these deceptions all took place in the Middle Ages, when modern science had not yet been established, and people did not know that the elements could not be transformed under normal circumstances, so it was easy to be deceived by rhetoric and magical performances. However, it is difficult to understand if anyone still believes in alchemy, but in the thirties of the twentieth century, there were two such deceptions in scientifically advanced Germany. ---introduction

"Whew......"

The screams of pain shook the sky and startled a crowd of birds.

The two knives hit, Feng looked at the large pool of blood on the ground, his heart shook suddenly, and he immediately burst out.

"Giving birth!" "Warcraft has a baby?" "His sister's is still a difficult birth." "What's going on?"

Not only that, but Feng also saw a huge demonic beast head, and directly told him that this was the head of a fifth-order demonic beast of the Great Perfection.

The appearance of the head of the fifth-order demonic beast of the Great Perfection was even more like a dose of stimulant, and the whole person was boiling, his eyes were full of golden light, and he said with a smile: "Kill one get one free, this deal is cost-effective." ”

The bloody-eyed mane lion is indeed giving birth, and as the wind says, it is still a difficult birth.

For the demonic beasts, when one lord is weak, there must be other demonic beasts looking for breath to provoke and fight for the territory, and the head behind the bloody-eyed mane is a Great Perfection fifth-order demonic beast, fighting for a day and a night, the whole body collapsed, and at this time it was facing childbirth, and suddenly entered a state of weakness.

If it weren't for the weak state, the wind would have been slapped into flesh by it a long time ago, and then it would have made him close? Under the buttocks, the blood was dripping, the blood-eyed mane wild lion wailed hard, the blood-red eyes turned dark red, the red ones could drip blood, and he stared at the wind angrily, his front paws were slightly suspended in the air, and he stepped back and held it up hard......

It's ready to attack.

The wind opened his eyes and was shocked.

At this moment, the blood-eyed mane lion's retreat softened, and his buttocks fell to the ground again, blood gushed out from under his buttocks, and a small blood-eyed mane lion was struggling hard, its small mouth open, and it wanted to make a sound in pain, but it couldn't make any sound.

"Good Opportunity ......"

"Brother Lion, don't say I'm ruthless, there's no way, who made you handsome."

The wind controls the crystal nucleus in the dantian, and as soon as the idea goes down, the crystal nucleus immediately floats, and the light purple circle flashes out, and the system keeps prompting: "Increase the qigong value by 100, increase the total energy value by 100 ......"

Then, there was the tornado divine power superimposed on the supernatural rage.

Raise your strength to the top again.

This blow is bound to hurt it badly!

The wind kept changing positions, and the blood-eyed mane mad lion's body collapsed, and his reaction couldn't keep up at all, but he just grabbed and released an incomparably powerful wind blade, and the wind blade slashed everywhere it went, and the towering trees kept collapsing, a mess!

Constantly dodging the wind blade, approaching little by little, under the fury of the supernatural powers, the dragon in the depths of the dantian, the two forces of the divine dragon scroll were frantically intertwined and released.

Strength, the wind can clearly feel the power of every part of the body.

The qigong exploded, the full energy skyrocketed, the wind shouted, and an extremely powerful qigong/full energy flashed out on the bone knife, forming two purple-green giant blades, and the giant blades stabbed fiercely towards the stomach of the blood-maned mad lion......

"Whew!" "Whew! ","嗷��......"

After several screams in succession, its whole body convulsed in pain, and it wanted to roll, but it was afraid of hurting the child who had not yet come out, so it could only let out a miserable wail when it endured the great pain.

――――

I hope you can support it a lot...
