As their understanding of each other deepened, the senior brothers who had communicated with Lin Quan the most also learned about some of Lin Quan's deleted past experiences and his ability to purify and refine refining materials. Through their mouths, the news that Lin Quan usually relied on selling some purified refining materials to earn spirit stones spread throughout Qingfeng Valley. It's just that in the eyes of these senior brothers, Lin Quan, who can only refine some primary magic weapons at most, is simply an ordinary junior brother.

Such comfortable and cozy days passed in a flash. When Lin Quan fully comprehended the two alchemy classics, he gradually reduced the number of times he participated in various exchange meetings under the pretext that he needed to continue refining and cultivating, and gradually, Lin Quan faded out of the small circle of those senior brothers again.

After learning the basic alchemy systematically and completely through this time, Lin Quan consciously took a step forward in his understanding of alchemy. In particular, some alchemy tips introduced in the classics made him gain a lot. For this reason, Lin Quan confidently restarted alchemy.

Unfortunately, the wishes are always good, and the reality is just as cruel.

I don't know if it was because the elixir of the Great Perfection of the Qi Condensation Period was too difficult to refine, or if Lin Quan's own luck was too bad, thinking that he hadn't made any mistakes this time, Lin Quan's ambitious second challenge ended hastily. The finished "Qi Condensing Pill" didn't get a few, but the painful failure made him relive it again.

Oh no.

Although this time it also failed miserably, it cannot be said that there has been no progress at all. At least in the past half month, Lin Quan's Cheng Dan rate has increased slightly compared to the last time. Well, it's just a little bit, indeed.

"I have obviously done everything the best in this alchemy, why is the failure rate of the 'Qi Condensing Pill' still so alarming?" Lin Quan was puzzled by this.

If you want to refine the "Qi Condensing Pill" that is suitable for Qi Condensing Great Perfection monks to enhance their spiritual power cultivation, you need at least eighty years of medicinal Golden Pulp Grass. Just two retreat alchemy pills failed nearly two hundred times in a row, and even Lin Quan, who had the Yin Yang Pagoda, couldn't bear such a consumption.

Of course, after thinking seriously about the classics for two days, Lin Quan didn't gain nothing. At least he could be sure that there was nothing wrong with the alchemy he had learned. The reason for the failure should be in other aspects, and he already had a vague idea in his vague mind, but he couldn't grasp it for a while.

"Looks like we'll have to make another trip to the Scripture Pavilion. Maybe it would be more suitable to look for more alchemy experience classics this time. Well, let's do it. ”

The next day, Lin Quan left Qingfeng Valley early, and it took less than an hour to arrive at the Hidden Scripture Pavilion of Ningcui Valley in a hurry. After greeting Zhou Lao, he went straight to the second floor with ease and plunged into the alchemy classics.

After having a new idea, Lin Quan entered the Tibetan Scripture Pavilion this time and did not leave without finding two classics like last time. This time, he directly paid for four hours in advance, and calmly took out dozens of books that he thought were useful, and looked through them carefully. In the end, after repeated arguments and screenings, I picked out two alchemy tips that I thought were the most useful. Just when he was about to copy these two experiences first, suddenly, an ancient book called "Jianding" next to him came into his eyes. After a slight movement in his heart, he immediately took out the book and flipped through it.

"Jianding" is neither an alchemy experience, nor an alchemy classic. It is just an ancient book dedicated to the introduction of various types of ritual weapons. The author is a self-proclaimed "Lingding Sanren" who is a ten-layer small loose cultivator of condensation. At first, Lin Quan didn't care too much, he just looked at it casually with an indifferent attitude. However, when he saw the introduction of Danding, his face suddenly changed, and then he picked up the book and went downstairs.

"Elder Zhou, the disciple will copy these three classics this time. As soon as he arrived in front of Old Zhou, Lin Quan casually threw out fifty spirit stones and put them on the jade table.

"No problem, it'll be right away!" Lin Quan's generous act of paying five more spirit stones every time made Zhou Lao feel very good, and he was also extremely diligent in doing things.

In less than a stick of incense, Zhou Lao had already copied all three classics. He swept all the spirit stones into his storage bag with a smile, and said with a smile: "Lin boy, there are still quite a lot of alchemy classics. Why don't you look at it a little longer?"

"Old Zhou, the disciple has just come into contact with Dan Dao, and he still understands the truth that he can't chew it out. If there is a chance in the future, the disciple will come again. Therefore, it is sufficient to have these texts for the time being. For this Uncle Zhou, who likes to be greedy for a little money, Lin Quan is also very speechless. After a perfunctory sentence, he picked up the jade slip and left.

..................

After returning to his residence, Lin Quan couldn't wait to take out the "Ding Jian" and examine it carefully.

The book "Jianding" has less than 20,000 words, mainly introducing various tripod magic weapons in the world of cultivating immortals. What is rare is that it contains dozens of exquisite pictures of various tripod vessels. And under each illustration there are detailed annotations and comments of "Lingding Sanren". With such illustrated classics, it only took Lin Quan two hours to have a very intuitive understanding of the various commonly used tripod vessels in the immortal cultivation world.

According to the introduction of "Lingding Sanren", the tripods in the world of cultivating immortals can be roughly divided into three categories according to their uses.

The first is the "instrument ding". As the name suggests, this kind of tripod is of course used for refining weapons;

The second is "Danding". Nature is used for alchemy;

The third type is the "sacrifice tripod". It mainly includes tripods for all special purposes. These special types of tripod vessels can be used for a wide range of purposes, such as storing items, collecting certain special spiritual objects, sacrificing and even arranging arrays.

Since each type of tripod has a different function, it is natural to choose carefully when choosing a tripod. If you choose randomly, you will only get twice the result with half the effort. Seeing this, Lin Quan finally came to his senses. It turned out that he didn't have a problem with alchemy, but that he made a mistake in the choice of Danding.

As for how to distinguish the use of various tripod vessels, there is one easiest way, that is, to look at the number of "tripod ears". Generally speaking, the "instrument ding" is fixed with three ears. And "Danding" is only two-eared. As for those special-purpose "sacrificial tripods", in order to distinguish them, the number of "tripod ears" is at least four, and up to nine.

Seeing this, Lin Quan finally understood what the problem was. It turned out that the "Nine Peaks Ding" with nine legs and nine ears that he bought cheaply in the "Qingdanfang" at that time was not a "Danding" at all, but a special "Sacrifice Ding" that did not know the purpose. That's why he would fail so many times in a row when refining a slightly more advanced "Qi Condensing Pill".

"I really didn't expect that I have always prided myself on being smart, but I was so stupid when it came to this Danding. If you hadn't seen this "Ding Jian" today, I don't know when I would be pitted by this 'Nine Peaks Ding'!" Lin Quan shook his head, his face full of laughter and tears. "Forget it, eat a trench and grow wise, the top priority is to study the choice of Danding first. ”

After settling down, Lin Quan stopped thinking nonsense, and he continued to look through it carefully. Because it is not enough to distinguish only various types of tripods, each kind of tripod is also very different according to the different fire sources, Lin Quan must choose the most suitable Danding according to his own situation.

"Lingding Sanren" divides the fire sources used in each type of tripod vessel into three categories.

The first is the lowest-tier and cheapest "Spirit Fire Ding". This kind of tripod can only accept the natal true fire cultivated by the monk himself, and other sources such as earth fire, mortal fire, or spiritual charcoal cannot be used. Generally speaking, this kind of "spiritual fire tripod" is only used by ordinary monks in the condensation period, such a thankless tripod.

The second type is the "Earth Fire Ding". This kind of tripod can only accept the earth fire. Because earth fire has the characteristics of stronger firepower and longer lasting. Therefore, all monks with the support of their families or sects will choose to use earth fire resources to refine their weapons, so the "Earth Fire Ding" specially used to cooperate with earth fire came into being. And once this kind of tripod device appeared, it has become the most mainstream tripod in the world of cultivating immortals today.

The third is the "Earth Spirit Double Fire Ding" that integrates all the functions of the first two tripods. This tripod can be used for all fire sources at will, and the monk who owns this tripod can refine the elixir or magic weapon anytime and anywhere. It can be said that it is the favorite tripod of all those who live in a fixed place. It's just that this kind of tripod refining is difficult, and all the materials are also very valuable, and generally speaking, ordinary casual cultivators can't afford it even if they look at it.

Finally, the "Lingding Sanren" also specifically mentioned the relationship between the fire source when refining different grades of elixirs or magic weapons.

Most of the pills used by monks in the condensation period were low-grade pills, and the requirements for tripod and fire source were generally not high when refining low-grade pills. Basically, as long as a cultivator who has reached the tenth level of Qi Condensation, even if he only uses the natal true fire he has condensed, it is enough to refine all the Qi Condensing Stage Pills. However, if you want to refine a mid-level pill equivalent to that used by a condensation stage cultivator, it is different. Because if you want to further purify and condense the essence of all kinds of spirit grasses, you can't meet the requirements at all with the natal truth of the cultivator in the condensation period, and you must have a stronger fire source to support it at this time. Therefore, the samadhi true fire of the earth fire or condensation stage monk is a necessary condition. For example, if Lin Quan wanted to refine a mid-level pill like the "Spirit Condensation Pill", he would have to rely on earth fire.

"It seems that I have to go to Zixufang City tomorrow to spend some money. Well, it's best to buy a 'Earth Spirit Twin Fire Ding' directly in one step. In this way, even if you advance to the condensation stage in the future, you don't have to worry about Danding anymore. If you really can't do it, then you can only buy a good 'Spirit Fire Ding' first, and for now, you must hurry up and refine enough 'Qi Condensing Pill'. ”

After understanding the reason, Lin Quan was immediately relieved.

It's just a Danding, with his current cultivation in the Great Perfection of the Qi Condensation Period, even if he consumes more than 1,000 spirit stones at a time in the Fang Market, it will not be too conspicuous. What's more, he also has the title of a B-level disciple of the "Purple Void Sect", even if he doesn't open his eyes, he doesn't dare to have any thoughts about a Purple Void Sect disciple in Purple Void Fang City.
