The Earth Yuan Realm absorbs the Yin and Evil Qi of Heaven and Earth, and the Tian Yuan Realm absorbs the Yang Qi of Heaven and Earth, and these two kinds of Heaven and Earth Spiritual Qi are intertwined with Yin and Yang in the body, and over time, they can be condensed into Yuan Dan in the human body. Yuan Dan is the crystallization of the human body's mental power, condensed into Yuan Dan, which is a sign of stepping into the Yuan Dan realm. Yuan Dan is subdivided into nine stars, with one star Yuan Dan being the secondary, and Nine Star Yuan Dan being the highest. And the ultimate quality of the Yuan Dan depends on the level of Yin and Yang Qi that you absorb when you are in the Earth Yuan Realm and the Tian Yuan Realm. Therefore, the Earth Yuan Realm and the Tian Yuan Realm are both laying the foundation for advancing to the Yuan Dan Realm. Stepping into the Yuan Dan realm, Fang is really in the cultivation and entering the room. The powerhouses of the Yuan Dan Realm can stay in the air for a short time, but they still can't reach the point of flying in the sky. When a person enters the Yuan Dan realm, the Yuan power in the dantian will be compressed into a more powerful and pure energy, and this energy is called pure Yuan Zhengqi, like fighting cattle across the mountains and taking things from the air, these supernatural laws that have been passed down by word of mouth since ancient times, is the cultivation realm that cultivators reach after reaching the Yuan Dan realm.

I don't know what kind of [Innate Xuangong] level my cultivation has reached, but I feel that my body is in a very good state. Refreshed, deaf and clear, the whole body has reached an unprecedented level of comfort and properness, and what is even more amazing is that my skin looks crystal clear, and the blood vessels under the skin are also faintly visible, I can even clearly feel the flow of blood in the blood vessels and the operation of the meridians, this [Innate Xuangong] is really amazing!

At this time, my eyes were drawn to a wooden box placed in the corner, which I had never noticed before. I walked over and opened it, and there was a black-brown alchemy furnace and a book called [Shentong Deed] in the wooden box, and I opened the book casually, which described in detail the origin of the pill and the method of refining.

- True alchemy originated from Qin Shi Huang, who had crazy fantasies about immortal magic throughout his life. When Qin Shi Huang was in his 20s, he became obsessed with elixirs and "real human art". In order to achieve the purpose of cultivating immortals, Qin Shi Huang even moved the palace into the Xianyang underground palace, staying in it without leaving home, while reviewing the chapters, while "leading" the immortals, and not allowing outsiders to disturb. "Alchemy" is a method used by the ancients to refine elixir in pursuit of "longevity". Dan refers to dansa or mercury sulfide, which is an inorganic compound of sulfur and mercury (mercury). Dansha is different from plants and trees, not only does it burn but does not ember, and the longer it is burned, the more wonderful the change becomes. Between heaven and earth, there is no immutable thing, all substances can change, as long as there are appropriate conditions and the spirit of persistent pursuit, some substances may become precious elixir and gold through smelting. However, sulfur and mercury are gold and stone medicines, which will be toxic in the process of smelting, and in order to remove the toxicity of gold and stone drugs, it is necessary to adopt the method of 'Fu Huo', which is as follows: use two taels of sulfur and two taels of stone to grind into powder, put them in a silver pot, light the three soaphorns one by one, and then put them into the pot to burn the sulfur and the stone to make fireworks. When the fire stops, then take three catties of raw and cooked charcoal and fry it, wait for one-third of the charcoal to be annealed, and take out the mixture when it is not cold, which is the specific process of "Fu Huo". The principle of this method is to make the drug burn on its own fire, so as to remove its toxicity. This book is the crystallization of my life's work, if the destined person gets this book, he should be in the heart of helping the common people in the world, and not in order to satisfy his own selfishness, arbitrarily act. This alchemy furnace is called Shennong Ding, which is made of ancient dark iron, and all evils are inviolable. If someone who is destined to get this tripod, beware of good thoughts, remember, remember!"

I once heard my master Li Yunshen say: "Since Qin Shi Huang, the emperors of all Chinese dynasties have had a strong interest in the immortal golden pill, especially in the Tang Dynasty, there were a total of 21 emperors, at least 5 of whom died because of poisoning by taking pills, they were Tang Taizong, Tang Xianzong, Tang Muzong, Tang Wuzong and Tang Xuanzong. In the Qing Dynasty, Emperor Yongzheng was also very obsessed with pills, not only opened a special alchemy venue in the Old Summer Palace, but also rewarded the refined pills to the princes and ministers around him. Although there are often cases of poisoning and death by taking pills, all dynasties and dynasties, from emperors to ordinary people, have not changed their obsession with pills. ”

- "Is there an elixir of immortality in this world?" Qin Shi Huang sent Xu Fu to Penglai Immortal Island in the East China Sea to seek the elixir of immortality, was there such a thing?"

Li Yunshen smiled at the time and said to me, "Everything is possible, if Master tells you that Qin Shi Huang is not dead, will you believe it?"

- "This is impossible, didn't Qin Shi Huang die a long time ago! This is clearly written in the history books of junior high school, could it be that Qin Shi Huang really ate that immortal elixir?"

- "Xiaohu, heaven and earth are full of aura, it's just that ordinary people don't know how to absorb and refine this aura. Throughout the ages, how many alchemists want to refine the elixir of immortality, but how many people are really successful? This is because they have not really understood the core mystery of alchemy, for most alchemists, they all understand the importance of alchemy medicinal materials, alchemy utensils and alchemy heat, but they ignore one of the most important factors, that is, the cultivation of alchemists. Because the most important part of alchemy lies in the refining of the aura of heaven and earth. The so-called aura of heaven and earth refers to the essence of heaven, earth, sun and moon in those medicinal materials, the essence of this kind of grass and trees will volatilize to form a gas in the process of high-temperature flint smelting, and the gathering and refining of this qi is the key to the success or failure of the elixir, and the success or failure of alchemy depends on the cultivation realm of the alchemist, elixir, elixir, only the elixir refined by the gods is called elixir, do you understand this truth?"

It dawned on me that with my current cultivation, I should be able to refine some pills!
