"What do these paintings have to do with Concubine Su's death?" the emperor was puzzled.

Nangong Yuhuan said: "To be exact, these paintings have nothing to do with Concubine Su's death, but the pigments in the paintings have a lot to do with it. Nangong Yuhuan explained.

"What does the paint in the painting have to do with that?" the emperor was even more inexplicable.

"You see the peacock feathers in this painting are lifelike, the emerald green peacock feathers are brilliant, and the tail feathers of the peacock seem to be gorgeous gold and emerald jewelry. Even the glitter on the feathers is depicted, and the paint used should be more unique, right?" Nangong Yuhuan did not answer the emperor's words directly, but pointed to a picture of a peacock hanging on the wall.

"Of course, I know that Concubine Su likes to paint, in order to make her paintings more beautiful, but in Nanhua to find pigments everywhere, from plants to minerals, but everything with bright colors and good coloring is made into pigments for her, you see that the sparkling is mica, the golden color is lapis lazuli, and the emerald green can also change color is the color-changing stone...... They are all extremely precious. The emperor said with a little pride: "Not only did I make a lot of precious pigments for the pigment maker, but the concubines of the harem also gave Concubine Su a lot of precious pigments and rough stones, so I can draw so many beautiful words." ”

Nangong Yuhuan nodded and said, "I can see that the color of the paintings in Concubine Su's palace is not found elsewhere." But it was these things that killed her. ”

"Why is that?" the emperor still didn't understand.

Nangong Yuhuan explained: "These paints can be said to be spiritually sufficient and colorful, which is also a good look for us, but for Concubine Su, they are all highly poisonous." For example, this cinnabar contains mercury, Daiqing contains lead, goose yellow contains arsenic, etc., the more colorful it is, the more toxic it is. ”

"Even if these pigments are poisonous, but Concubine Su didn't eat it?" the emperor was a little unimpressed.

"Some things don't have to be eaten, and radiation alone can kill people. "Nangong Yuhuan Road.

"If you say so, then it shouldn't be Concubine Su alone, why are so many palace maids and eunuchs in the palace fine?"

Nangong Yuhuan said: "The palace maid and eunuch you chose for Concubine Su are like Concubine Su, who is completely a mortal who can't cultivate. ”

The emperor was stunned for a moment and said, "This doesn't seem to be true." ”

"That's it. Nangong Yuhuan said tactfully: "Just like the elixir we eat, it is made of burning lead and smelting mercury, so let's say that the most cheap Taiyi Divine Essence Pill that can't even be called a first-grade pill is made of dansha, Zeng Qing, male yellow, orpiment, magnet, and gold tooth, what does the emperor think is wrong?"

The emperor thought for a while and said: "This Dan prescription is also ordinary, according to me, the Dansha in this prescription rules the five internal organs and all kinds of diseases in the body, can nourish the spirit and calm the soul, invigorate the qi and eyes, kill the essence and charm, and can pass through the gods for a long time; Zeng Qing is the main wind paralysis, the joints, the nine orifices, and the accumulation of broken diseases; the realgar can also kill sperm, evil ghosts, and a hundred insects; orpiment can cure sores and poisonous insects, and the body is itchy and evil; the magnet can cure the paralysis of the periphery, and the pain in the rheumatoid joints cannot be held; the gold tooth repels the ghost and the poison, and the muscles and bones are cramped and the waist and feet are not successful. This recipe is purely stone-based, and it is specially designed to ward off evil poisons. ”

Nangong Yuhuan praised: "The emperor really knows a lot about the art of Waidan, and the concubine has seen a poem "Burning Dan" written by you before, and the poem Yunyun: "Lead sand and medicine, pines and cypresses surround the cloud altar." The furnace transports yin and yang fire, and the power is both internal and external. "At that time, I thought it was very well written, and when I look at it today, it is really a famous person!"

The emperor smiled and said: "Aiqing praised it falsely, where do I know what alchemy is, I just watched people be a little curious about alchemy, and I was interested in writing it for a while." ”

Nangong Yuhuan smiled slightly and said, "Even if you don't know how to refine the pill, the emperor should have a lot of research on the way of the pill, right?"

The emperor smiled: "It's not that to talk about, but I just know a little bit about it." ”

Nangong Yuhuan raised his head slightly and said: "The concubine only knows that the pills eaten by different cultivation realms are also different, and the cultivation of the Transformation Period is a waste to ask for the Divine Realm, and in the same way, the monks of the Sanhua Realm have eaten the pills of the Transformation God Realm, it is not only as simple as wasting the pills, it is more likely that they can't digest it, and they will be strangled to death by the energy in the pills, I don't know if what the concubine said is right?"

The emperor nodded and said, "You are right, you mean to say that Concubine Su is a mortal, and she can't absorb and digest a large amount of spiritual power in this hall, so she was killed alive?"

Nangong Yuhuan said: "If it's just a simple spiritual power, it can't do anything, after all, the power of the five elements is quite balanced, but the paints in this painting are all very biased, and after coming and going, Concubine Su will inevitably fall ill." ”

The emperor nodded and said, "I see, it seems that I am not blessed to receive the grace of the beauty!" The emperor sighed and said, "But how do you know this?"

Nangong Yuhuan smiled lightly: "Have you forgotten where I came from? Our Shenzhou is not as good as Zuzhou, most of them are mortals, and they also want to learn from our cultivators to eat the cultivation elixir, and they like the technique of "furnace fire cultivation", so many people have died." Later, after these lessons, the cultivation technique of the Outer Dan Furnace Fire gradually weakened, but many of the refining methods they invented also had merits. ”

"Oh, what are the wonderful methods for refining the Outer Pill from the people of the Ancestral Continent?" the emperor was interested when he heard it.

Nangong Yuhuan said: "The most important ones are: flying, rising, pumping, volting, pointing, closing, raising, boiling, refining, forging, grinding, sealing, and so on dozens of methods. In addition to these, there are many other ways to operate the Waidan. Corresponding to the method are the steps of refining, such as entering the yang fire, retreating the yin charm, collecting medicine, refining medicine, and so on. ”

"Wait, Aiqing, can you elaborate on what those ten methods mean?" The emperor asked with a slight frown.

Nangong Yuhuan said: "The so-called "flying" refers to the fact that the solid medicine in Danding is directly converted into vapor without going through the liquid state through the heating action of the furnace fire. "Sheng" has the meaning of sublimation, and its steps are basically similar to "flying", that is, to sublimate solid medicine through heating. These two are just one fast and the other slow. The fast transpiration is called flying, and the slow transpiration is called rising. ”

"Pumping" refers to the heating of raw materials to a boiling state, which vaporizes some of them, and then cools and condenses them into a liquid, which is then collected. "Volt" refers to the processing of those substances that are more active and unstable in nature through some means to make them stable. "Point" refers to the addition of a small amount of reagent to a large amount of substance to change its properties. It's a bit of stone-to-gold. ”
