The alchemy method recorded in this fragment is different from that of ordinary alchemy. The ordinary method of alchemy is to use Danding to refine, put the required materials in the Dan furnace in order, and use mana to transform Danding into Danding fire for refining, or find natural places such as earth fire and sky fire, and use Danding to absorb earth fire and sky fire for refining. It's the same with refiners. This fragment tells a completely different story.

Heaven and earth are furnaces, creation is work, yin and yang are charcoal, and all things are copper......

With his own body as the furnace and the soul as the work, Jin Dan transforms yin and yang into a supreme furnace......

This...... This is too crippled, what is it? With the body as the peak, it is so difficult that I have to swallow the alchemy materials in my stomach first, and then spit it out after refining the pill? But it is convenient to eat it myself, Zhu Yuan joked. It's so difficult to turn yin and yang into yin and yang! I haven't reached the golden pill stage yet. Zhu Yuan thought so and continued to watch.

The most important things in alchemy are Danding, Danfang, materials and people. Only a good Danding can refine a good Dan, and the success rate of alchemy is high. For example, the Dan refined with a magic weapon-level Danding and an Immortal-level Danding must be a Dan refined by the Immortal Ding with a high success rate, a high grade and a large number, and besides, it is impossible to refine the Immortal Pill with a magic weapon-level Danding. Alchemy has high requirements for Ding. Alchemy also requires Danfang and materials, which are also indispensable. The most important thing is people, and the requirements for alchemy are very high. It is required to know the properties of each material very well, and to control the heat in the alchemy process, when to use simmering fire, when to use martial fire, these have strict requirements. If one is not well controlled, a furnace of pills will cost. There is also a big problem with alchemy, that is, you can't just rely on your own mana to transform it into a furnace fire through Danding, because it is consumed quickly, and your personal mana will be consumed quickly. Alchemy is done in one go, and you can't wait for the mana to be restored before continuing to refine, in that case, a furnace of elixir will be destroyed. You can't just rely on absorbing the Yuan Power of Heaven and Earth to refine, because that fire is difficult to control. Therefore, it is very difficult to become a good alchemist. For various reasons, many schools of alchemy have also been created.

And the alchemy method recorded in the nameless fragment is a unique alchemy method, which relies on mana in the body to refine. The heat is well controlled, and the success rate is high. However, the difficulty is to use one's own body as a furnace and the soul as the work, which is understandable, that is, to control the process of alchemy by relying on the divine soul, it is also difficult to do the golden pill to transform the two qi of yin and yang, which requires the monk to practice both yang attribute and yin attribute exercises, and it is very likely that he will go mad and die......

"Is this crippled alchemy method feasible?" Zhu Yuan looked behind as he thought about it.

Washing the marrow pill, as the name suggests, washes the essence and cuts the marrow. A person is born with impurities in the body itself, and they will slowly accumulate and become more and more. People themselves will also have bad blood and have problems of one kind or another. There are many influences on cultivation. After taking the myelin cleansing pill, the impurities in the body will be completely discharged. As a result, the speed at which the monks absorb the vitality of heaven and earth will be accelerated, and the cultivation will be faster. To a certain extent, the monk's sense of the Tao can be enhanced. Moreover, after a person is born, due to various reasons, the body will have a little deformity, although it is very small, and it is usually not visible at all, but it has a great impact on future cultivation. Especially martial immortals, because martial immortals are close to the body, a little uncoordinated body will lead to stiff and incoherent movements, and melee combat is the most dangerous, even a little negligence is fatal. Therefore, the myelin cleansing pill seems to be ineffective, but it is actually a very valuable elixir.

Zhuyan Dan, as the name suggests, is an elixir that can make people stay young forever. People are dying little by little from birth. Immortal cultivators are no exception, but the rate of aging of immortal cultivators will be slower. Unless you become an immortal, you can transcend life and death, not enter reincarnation, and your face will remain forever from now on. Therefore, many immortals are like old men and old women, because they are old when they become immortals, and they can only maintain the appearance when they became immortals. The appearance will be a little better for the friar, and it will be nothing to be old. But it's different for female monks, of course they want to be young and beautiful, but there is no time for cultivating immortals, and they can't become immortals if they want to become immortals as soon as possible. The effect of the anti-Yan pill is that you can always maintain your appearance when you take the pill, even if you can't become an immortal in the end, your face will not change when you get old. Another point is that you can't eat too early, and when you are young, you will always be a child. This elixir, like the Cleansing Pill, can also be taken by mortals. Definitely the most wanted treasure of all female monks.

Tian Yuan Dan is an elixir that restores mana. Monks generally rely on slowly absorbing the vitality of heaven and earth to recover their mana, but if they encounter special circumstances and do not have such a long time to cultivate and recover their mana, they can only rely on pills to recover. Tian Yuan Dan is such an elixir, which can quickly restore mana and heal injuries. Generally, the pill can only recover a small amount of mana at a time, and it has to be refined by itself, but relatively speaking, it is much faster than absorbing the Heaven and Earth Yuan Qi. However, Tian Yuan Dan did not have so many scruples, it could directly recover to its peak mana, and it could absorb it directly into its own mana without refining. Tian Yuan Dan is actually two unilateral parties, one is Tian Yuan Dan and the other is Di Yuan Dan. The materials used in the two are different, in fact, the Diyuan Pill is an ordinary elixir, which can restore all the mana of the immortal cultivators in the Jindan stage at one time, while the Tianyuan Dan is considered an elixir, and can restore almost all the mana of the immortals at one time.

Seeing this, Zhu Yuan's heart was hot. What Zhu Yuan wants most now is the Cleansing Pill, as a person who fights in close combat with a sword, this pill is too important. And Zhu Yuan's swordsmanship has also reached a bottleneck now, he does find that he has a little problem with his body and has defects in his swordsmanship, so he has not been able to break through. Seeing the introduction of the Cleansing Pill, he suddenly understood what it was. Because of his own body, he was a little unsmooth when practicing swords, and his swordsmanship was not perfect, and he couldn't break through.

The nameless fragment only recorded these three Danfangs, but as for the refining artifacts, there was no mention of them. The nameless fragment also said that alchemy and refining are the same, and since it is not mentioned here, other magic weapons can also be refined. Anyway, the Qingyun Sect has many ways to refine magic weapons, and refining magic weapons with the method of alchemy is the same, as long as there are materials for refining magic weapons and the process of knowing the Dao.

Now Zhu Yuan wants to refine the marrow cleansing pill immediately, not only for his own needs, but also for his father, mother, and Grandpa Liu. Anyway, it doesn't hurt to take it. As soon as he said and did it, Zhu Yuan immediately left the Hidden Scripture Pavilion and returned to Mochizuki Peak's own secret room to start cultivating.
