Although Tian Yinzhen's mana cultivation had reached the Great Perfection of the Qi Refining Period, and she could basically start building a foundation at any time, she faintly felt that after she cultivated the Great Yin and Yang Reincarnation Sutra, it seemed that this was not the apex, and the facts also told her that this was indeed the case, unlike others, once the mana of other monks reached a bottleneck, no matter how they cultivated, it would be impossible to make any progress, unless they broke through the current stage. However, Tian Yinzhen could feel that although her cultivation growth had stagnated, with the continuous deepening of her cultivation, her strength was still growing little by little, since this was the case, she was not in a hurry to break through before she obtained the best Zhuji Dan.

Since knowing that there is the existence of the best Zhuji Dan in this world, Tian Yinzhen has already made up her mind that she must use the best Zhuji Dan to build the foundation, and the use of the best Zhuji Dan to build the foundation is much more beneficial than using the ordinary Zhuji Dan to build the foundation.

First of all, the success rate is naturally higher, at least two percent. The success or failure of the foundation building is related to the cultivation future of the future life, so no one will not pay attention to their own foundation building, but the success rate of building the foundation is too low, there are almost no people who succeed without using the foundation building Dan, and the success rate of using the ordinary foundation building Dan is less than two percent, but the success rate of the best foundation building can increase the success rate of the foundation building by two percent on this basis, which is almost equivalent to doubling.

Tian Yinzhen estimated that the mana of the "Great Yin and Yang Reincarnation Sutra" that he cultivated was three times deeper than that of the same level, and the difficulty of breaking through was probably also increasing in geometric progression, even if his talent was good, he didn't dare to say that he had a certain grasp of a breakthrough in the face of this top-level exercise.

Every breakthrough is a process in which a cultivator's vitality is greatly damaged, and generally speaking, if the same realm does not break through twice in a row, the possibility of a successful breakthrough for the third time is very small. She didn't intend to joke at all about this kind of thing related to her future future, since she knew that there was a top-grade Tsukidan, then when she built the foundation, of course, she should use this pill as much as possible.

The second benefit of the best Zhuji Dan is naturally to strengthen the foundation of Peiyuan, and enhance the role of the foundation after the success of the foundation, and this role is also not possessed by ordinary Zhuji Dan, although it is nothing compared to the first role, and it is too luxurious to use the best Zhuji Dan to consolidate the foundation Peiyuan, but Tian Yinzhen still plans to try it hard.

Tian Yinzhen knew that most of her knowledge did not have a fire spirit root, but she seemed to have some talent in the cultivation of water spells, it seemed that she might have a good water spirit root, and the practice of water refining alchemy would become a good choice for her.

Taking out the jade slip that Qi Rang gave him, Tian Yinzhen put the jade slip on his forehead, calmed down completely, and began to read the jade slip.

Reading the jade slip this time, I naturally don't want to look at the flowers like before, but carefully savor it word by word.

Tian Yinzhen first read all the refining methods of the best Zhuji Dan, and couldn't help but praise from the bottom of his heart, this Qi Rang is really a genius of alchemy, and he actually came up with an alchemy method that the ancients never dared to try: the three-yuan alchemy method, that is, to refine three identical pills at the same time, with one as the main pill, and the other two as auxiliary pills, the three pills are refined at the same time, but they are fused with each other in the link of melting the pill, and finally form a pill, then the medicinal power and medicinal properties of this pill are naturally much stronger than an ordinary pill, and it has become the legendary best pill。

Of course, this process is simple to say, and there are many problems and troubles to deal with, but Qi Rang also made a detailed explanation in each link, which is like splitting each link of a very complex advanced mathematics problem in front of the students, and all of them give specific operation formulas, and the result is that the difficulty of the problem has been reduced by several times, but even so, Tian Yinzhen does not have the slightest alchemy foundation, and it still seems to be in the clouds, and even the basic medicinal properties of some medicinal materials are not very clear。

Thinking of this, Tian Yinzhen couldn't help but smile bitterly, and secretly said that he would have to make up for the lessons in the future.

After reading the refining method of the best Zhuji Dan, Tian Yinzhen immediately found the link of "The Method of Water Refining" that he wanted to learn, and began to read it seriously.

Perhaps considering the lack of basic knowledge of alchemy by the people who studied this jade slip, Qi Rang explained the most basic knowledge of alchemy in detail in the first chapter of "The Law of Water Refining".

After reading it, Tian Yinzhen suddenly had a feeling of sudden realization in his heart, it turned out to be like this.

The so-called alchemy, in fact, does not start from the skills of alchemy itself, but only for the alchemy itself, it is nothing more than two important issues: one is the problem of how to refine the material to condense the essence, and the other is the problem of stimulating the medicinal properties and successfully fusing the medicinal properties of a variety of medicinal materials to form the elixir.

The quality of the elixir is seventy percent due to innate factors, and the acquired alchemist's technique accounts for thirty percent, but this is not to say that the alchemist is not important, if there is not enough alchemy skills, then even if the elixir is successfully refined, it can only be a waste pill and an inferior pill.

The waste pill is completely ineffective, and the medicinal power of the inferior pill is also very weak, these two kinds of pills are not only useless but harmful to the human body, and the monks who use the inferior pill to build the foundation will not be able to make any breakthroughs in their lives, and they are also the worst among the cultivators in the foundation building period.

It is precisely because of the first problem of how to refine the essence of the material, so the method of fire refining came into being, there is a way that real gold is not afraid of fire refining, fire is the most rigid and yang thing in the world, calcining with fire, can remove any impurities and dirt in the substance, leaving only the most essential part, and fire can also catalyze the maturation process of a pill, so that it can be solidified as quickly as possible, virtually reducing the risk of alchemy failure, so since ancient times, the method of fire refining has been popular, and almost all cultivators believe that only the monks of the fire spirit root have the potential and qualifications to become alchemists。

But is this really the case? Of course, this is not entirely the case, in fact, any spiritual root cultivator has the possibility of becoming an alchemist, of course, this is only a theoretical possibility, as long as your mana is endless, you can remove all the impurities in any material, and then use the Dan fire to calcinate at the expense of self-cultivation, you can always practice the spiritual pill, but no cultivator will do this, because it is simply an act that outweighs the loss.

But there is an exception to the spiritual root, that is the water spiritual root, according to the theory of water and fire, and mutual restraint, the effect of quenching impurities that fire spiritual power can play, in fact, water spiritual power can also be done, and it is true, from ancient times to the present, many cultivators have made attempts in this regard, and they have indeed achieved some success, but this road has come to the end, they are faced with a new problem, there is that the attributes of water spiritual power are still too soft, some very stubborn impurities, maybe through the calcination of fire for a few hours can be peeled off, and the washing of water may take ten or even twenty days, What's more, the alchemy of water spiritual power is still facing a more difficult problem to overcome, that is, how to better condense the pill, as long as the fire spiritual power is controlled within a reasonable range, it can assist in the rapid condensation of the pill, but the water spiritual power is better at turning the pill, and it is not helpful for the condensing pill, because the inherent property of water is originally dissolved.

It is precisely because of these many difficulties that many people think that the method of water refining is feasible, but there is almost no success, and ninety-nine percent of the classics of alchemy are all about the method of fire attribute alchemy, of course, this does not mean that the cultivators of the water spirit root are inferior to the cultivators of the fire spirit root, they naturally have other good at it.

The cultivators of the Water Spiritual Root have specialties that are not matched by other Spiritual Root cultivators in terms of healing injuries and preventing them from going mad, and it can be said that the Five Elements Spiritual Root is not simple regardless of priority.

Qi Rang's alchemy experience gave a completely different opinion from others, he believed that the cultivator of the Water Spirit Root could not only alchemize, but also become an alchemist, and was not inferior to the alchemist of the Fire Spirit Root, and what he used was the solubility of water that was not favored by everyone.
