In the blink of an eye, Nie Fei came to the Hundred Refining Gate, and Lin Qiao's residence had been seven days.

After coming, Nie Fei found that this Hundred Refining Sect was really a big sect, and the entire sect covered no less than two hundred miles, and this was only a place where there were buildings. If you count the entire sphere of influence of the Hundred Refining Sect, at least it is thousands of miles away. Nie Fei thought of the Fenglin Sect, and the sphere of influence was only two hundred miles, so it can be seen that this Hundred Refining Sect was many times larger than the Fenglin Sect.

After arriving at Lin Qiao's residence, Nie Fei took a closer look. This is a courtyard more than two miles deep, most of which is covered by some medicinal herbs and other plants, and there are several buildings in it, with cultivation rooms, residences, and so on. The most ambitious building is the Alchemy Room, which is a huge stone room with three stories high, which is the location of Lin Qiao's alchemy.

Lin Qiao arranged him in the last cabin for the disciples to live in, and went to take care of himself. Only then did Nie Fei realize that he was the only disciple of this Lin Qiao. During these seven days, Lin Qiao only briefly explained to Nie Fei the rules of the Hundred Refining Gate, and gave Nie Fei in great detail how to make fire, how to fan the wind, and how to observe and control the fire when refining the pill. He explained these things to Nie Fei in one day, and then ignored Nie Fei.

Lin Qiao's attitude was very much in line with Nie Fei's mind, and he wished that Lin Qiao would ignore him.

Taking advantage of this time, Nie Fei used more than a hundred Soul Relief Herbs to remove their drug resistance with Fire Feather Pill, and obtained a total of ten bottles of medicinal liquid. He didn't drink these medicinal liquids immediately, but put them in a storage bag for later use.

By this time, all the Spirit Relief Grass on his body had been used up, and he urgently needed to buy some more Spirit Relief Grass. One day, he went out to inquire about the Spiritual Herb, and what made him feel terrified was that none of the people he inquired about knew what the Spiritual Herb was, and they had never heard of the herb Spiritual Herb at all.

What this meant, of course Nie Fei knew in his heart, it meant that if he couldn't go back to Heavenly Spirit Fort immediately, then his cultivation could only be improved to the point where all the remaining bottles of Spiritual Relief Herbal Liquid were consumed. By that time, his cultivation would have come to a standstill.

But the earthly world is vast, and when he returns to Tianling Castle, maybe how much time will be in the future. Maybe half a year, a year, or even ten years. Could it be that cultivation is fixed here?

No, absolutely not. Since there is no Soul Herb, then find other herbs instead, Nie Fei doesn't believe it, the Immortal Cultivation Realm is so big, so the Soul Herb is a kind of herb, which contains immortal nature.

......

In the middle of this courtyard, there is a place that resembles a study. What is hidden in it is, of course, not ordinary paper books, but replaced by jade tablets and jade slips, as long as the immortal cultivator's divine sense penetrates, he can understand the contents.

One day, Nie Fei walked into the study, and then soaked in it almost all day and all night.

Of course, his original intention was to find a medicinal herb that could replace the Soul Relief Herb. However, he didn't find the herbs, but he had a comprehensive understanding of the knowledge of alchemy.

The reason why the Hundred Refining Gate is called the Hundred Refining Gate is divided into the outer door and the inner door. The outer gate is mainly for practicing various exercises, and each exercise is outstanding and very combative. Their role, in addition to protecting the sect, also provides materials for the inner sect's alchemy refiners. The reason why the outer gate is called the outer gate shows that their status is not the core.

The real core of the Hundred Refining Gate is the inner door. That is, alchemists and refiners. Alchemists mainly refine various pills, while refiners refine all kinds of treasures and magic weapons. In the Hundred Refining Sect, as long as he is an inner disciple, his status is very high. Nie Fei found that he was very lucky to be an inner disciple. However, he is only listed, not official.

Because, his master, Lin Qiao, is the elder of the inner gate. The apprentice is a teacher, and the tide rises, and he, the only disciple of Lin Qiao, naturally has a lot of elevation.

Nie Fei's master, Lin Qiao, is an alchemist. The classification of alchemists is generally determined by the grade of the elixir refined, and has nothing to do with cultivation. For example, Lin Qiao can only refine a first-level pill now, so he is a first-level alchemist, and it has nothing to do with whether he is a cultivator in the foundation building period. In the Hundred Refining Sect, ordinary alchemists can be reached in the Qi refining period, and it is very rare for Lin Qiao to be a first-level alchemist in the foundation building period.

But alchemy has nothing to do with cultivation, but it can't be said either. When refining the pill, it is necessary to inject spiritual energy into the Dan furnace, which has something to do with cultivation. In short, a cultivator in the Qi refining period, no matter how good his talent is, he should not think of refining a second-level elixir.

In addition, according to the different qualities of alchemy, the elixir is divided into ten grades. Generally speaking, the pills above the fifth grade are the best goods, and there are so many alchemists in the Hundred Refining Sect, and there are few people who can refine more than the fifth grade.

Nie Fei looked at it and couldn't help but be fascinated by this alchemist. This yearning for an alchemist is not his unrealistic idea, to say that alchemy, similar to chemistry, he has a foundation, and it is by no means impossible to become an alchemist.

However, when Nie Fei continued to look down, he found a restriction on alchemists. As soon as he saw this restriction, Nie Fei couldn't help but be dumbfounded. It clearly says that if you want to become an alchemist, you must practice wood aura, and this is a must. Because alchemy, to put it bluntly, is dealing with medicinal herbs and stones, and this wood aura can play a role. In addition, in addition to this, it is written above that people who cultivate fire aura at the same time are the best choice for alchemists. If you cultivate fire aura, you can control the heat during alchemy, which will undoubtedly greatly increase the success rate of alchemy.

"Do you have to cultivate Wood Aura?" Nie Fei was a little disappointed, he had never cultivated Wood Aura, he could barely be regarded as having cultivated a few Fire Aura, but Fire Aura was not a necessary condition. He sighed and thought to himself, "It seems that he can't be an alchemist." ”

In addition, among these jade slips, there are also many alchemy methods of pills, such as first-class pills such as Qi Gathering Dispersion, Xiao Huan Dan, and Hui Qi Pill. But Nie Fei thought that he couldn't do alchemy, so he was not interested at all, but after glancing at the names of these pills, he didn't look at it anymore.

......

On the eighth day that Nie Fei came to the Hundred Refining Gate, Lin Qiao finally walked out of his room and called Nie Fei over.

It turned out that these days, Lin Qiao was preparing materials and planning to refine an elixir called Detoxification San. Although Lin Qiao is an alchemist, he is still an alchemist in the foundation building period, but it is precisely because of his cultivation in the foundation building period that he is not valued in the sect. The reason is that alchemy is a thing that depends on talent very much, and an immortal cultivator, whether he is an alchemy talent or not, can generally see some signs at a very young age.
