In the early morning, Gao Yue, who had palpitations, sat in the middle hall of the official residence, and Wu Cailuan on the opposite side had been led by Yun Shao to clean it, and finally grew long hair, and burned part of it, so it could only be wrapped in a man's head, but fortunately, it was not injured, but his face was sprayed with charcoal ash.

Then Cailuan cried and cried, talking about how he had ordered the sand and returned to the Yanyan Grange.

"I'm so stupid......" Wu Cailuan raised his eyes at this time and said slowly, "I only knew that it would be fine to cover the Dan furnace with a wet cloth, but who would have thought?" ”

"Who thought of that?" Gao Yue asked anxiously.

At this moment, Wu Cailuan seemed to remember something, and began to cry again, saying that the treasure book I spent ten times to buy is now all turned into ashes in the fire!

Yun Shao asked with concern what kind of treasure book, it was actually worth ten yuan.

Wu Cailuan replied, called "All Families of Gods and Gods".

As soon as he heard this name, Gao Yue hid his face, and the books with this kind of name were not reliable.

But then he was shocked.

In the past, I only knew that Wu Cailuan was a Taoist female refiner, and it was normal to go to alchemy, so I casually placed a Dan furnace in her grange, and then let Wu Cailuan go to Yunyou with full of excitement to collect Yin Yang Pill materials.

But at this time, Gao Yue slapped his face fiercely, and it didn't take much effort to shout.

He almost forgot that the world's greatest invention was born in the Tang Dynasty in which he is now located.

And the ghost sent God, Wu Cailuan, a female refiner, will also be recorded in the history of this era?

So at Gao Yue's strong request, Wu Cailuan intermittently restored the scene of last night's accident:

She spent two months collecting materials in the mountains of Xingyuan, the so-called Taoist alchemy needs, in fact, divided into two kinds of yin and yang, the so-called "yin medicine" is those stored in the mountain yin, cold water, dull color, good character, not easy to burn, such as saltpeter, mercury and lead; The so-called "yang medicine" is those things that are bright in color such as red, yellow, red and green, easy to fly when seen in water, flammable when seen in fire, and sublimated violently, such as sulfur, realgar, dansha, gold, etc.

Taoists believe that the core of the pill is "one yin and one yang", that is to say, the yin medicine and the yang medicine should be mixed and smelted according to the carefully explored ratio to form a pill, which can eliminate all kinds of diseases, immortality, and rejuvenation after eating.

In addition, the ruler liked this, so throughout ancient China, the nobles below the emperor liked to take pills, which was prosperous for a long time, and gradually in the Tang Dynasty, "pill medicine" also formed an extremely perfect "scientific" category, and the knowledge of yin and yang medicine marriage was getting bigger and bigger, and more and more sophisticated.

But if saltpeter and sulfur are mixed together and ignited with fire, it will produce a violent chemical reaction like the intersection of yin and yang, that is, deflagration.

This was known to the alchemists for a long time, after all, they were bombed I don't know how many times.

Therefore, for the sake of the safety of alchemy, the previous generation of refiners explored a set of "fire ambushing methods".

In fact, there are many meanings of ambush fire, as well as the meaning of eliminating the toxicity of the pill and suppressing the quality of the pill, but the most intuitive is actually to control the explosiveness of sulfur and saltpeter and prevent the furnace from exploding.

And Wu Cailuan took the fire method in the "Zhujia Shen Pin Dan Method": put out the yin medicine and yang medicine in the bag, then mix them together, pound them into fine powder in the bowl with a pestle, and then pour them into a clay pot, dig a pit in the ground, fill it with soil on all sides, and then find a pot, put the yin and yang medicine powder in the pot, and then install the pot in the pit, use iron tongs to pick up the burning soap horns, clamp them to the mouth of the pot, and make the yin and yang drugs burn, and at the same time, the soap horns can also play a "existential" role, that is, not to let sulfur and saltpeter deflagrate. Wait until three soaphorns are burned, and then put three catties of cooked charcoal on the mouth of the pot, let it "cluster serving", that is, the meaning of slow calcination, and wait until the charcoal is eliminated by one-third, you can open the soil pit, take out the pot, and get the burned elixir.

But after three or two times, Wu Cailuan always felt that it was not good, this fire could be subdued, but the burning was very insufficient, even if it was throwing soaphorns and throwing cooked charcoal to help burning, the pills that were finally pulled out felt that only seven or eight points were in place, far from reaching the tenth level of purity.

So Wu Cailuan carried out one of the few thoughts in her life, that is, between flammable and explosive and insufficient combustion, choose a balanced approach.

In the end, it was a coincidence that she flipped through the previous pill books and found that there was still something that could be "existing", and the strength was greater than that of soaphorn and cooked charcoal, this kind of thing was aristolochia, and it was also a flavored herb, which was found everywhere in Xingyuan Mansion, and its value was not as good as that of angelica.

The bold Cailuan refiner did what he said, so he went to collect aristolochia, and then grinded it into powder, mixed it directly into sulfur (yang) and saltpeter (yin), and added mercury, a little gold and other messy things, and also dug a pit of earth, poured the mixed powder into the iron can, and then burned a small stone of charcoal, and threw it into the mouth of the jar.

"Bang", her eyes suddenly blue and red yellow light flying, the whole sand back to the weir grange yard as if the thunder fire dazzling, in a few seconds "immediately see the disaster", the flames from the pit spewed higher and higher, soon the close to the various miscellaneous trees to peel off the strip on the ground, with the help of the wind swept up, and burned to the pillars, then the ridge, then the window lattice, the door frame and the floor furniture, immediately engulfed half of the grange house.

Fortunately, Wu Cailuan was far away at the beginning, and her arms and face were not burned, but her clothes and hair were stained with flying fire, which frightened her to hug her head and run away, "The true refiner will never look back at the explosion!" "First jumped into the weir pond and rolled in the water, finally stopped the fireworks on his body, and then climbed up without bothering to wash. At this time, the surrounding villagers rushed to put out the fire, but it was too late, and the entire Shahuiyan Grange had no skills.

"Yi Song I'm sorry, I, I will continue to copy the scroll for you as compensation. This grange is worth at least 300 yuan, and I will copy the scriptures for you for free for ten years. When Wu Cailuan said this, he was already so anxious that the six gods had no master.

At this time, she looked at Gao Yue with a stunned expression, and thought to herself that Yi Song would not be distressed and stupid......

He was even more anxious and worried.

"What is three hundred yuan, how can Qingqing be so stingy, just if the refiner is safe." This will Yun Shao hold Cailuan's arm and comfort him repeatedly.

Gao Yue's voice came at this time: "Master, do you still remember the formula for alchemy?" ”

"Remember, remember."

"Write out the formula, don't say 300 guan, it's 3,000 guan and 30,000 guan, and you don't need to compensate for anything." Gao Yue's tone actually quickly became excited.

Soon, Zhi Hui sat down with a pen, ink, paper, and inkstone and handed it to Wu Cailuan.

Xiao Kai was the specialty of the Cailuan refiner, and after she wrote it for a while, she handed over the paper with the formula of the alchemy subduing fire method to Gao Yue.

Gao Yue looked at it, and then said to Wu Cailuan, "Don't move around this month, remember this recipe, and then write down the scene of the burning Grange that day on a piece of paper, and then copy other books casually, and write this book signed as Alchemist Your Alchemy Book." ”

"It's okay to copy, but it's not good to sign yourself?"

"It's okay, you have aristolochia, sulfur and saltpeter smelting and deflagration in this book, which is enough to withstand all other alchemy, I have thought of the title of the book for you, it's called . ”
