Then, Nie Fei injected aura into another jade plaque. In this jade plaque, what is recorded is not the exercises, nor is it something that is classified and counted like poison medicine, but a detailed record of how the disciples of the Five Immortal Palace should build the foundation.

When Nie Fei saw it, he was interested. Although what is recorded in this jade plaque can only be said to be the experience of building a foundation specifically for the disciples of the Five Immortal Palace, Nie Fei knows very little about building a foundation, so he can learn from this experience.

It only took two hours for Nie Fei to read through this experience, and then thought about it. It turned out that the disciples of the Five Immortal Palaces were basically the same as the monks of other sects. In each sect, there is a special place to build the foundation, and the foundation building place of the Five Immortal Palace is called the Five Immortal Blessed Land. Once the Qi Refining Stage disciples of the Five Immortal Palaces have cultivated to the perfection of Qi refining, they can go to the Five Immortals Blessed Land to sit on the death pass and impact the foundation.

But for some reason, the success rate of the disciples of the Five Immortal Palaces in building the foundation was far lower than that of the disciples of other sects. Not only that, when the disciples of the Five Immortal Palace built the foundation, they also needed to take an elixir called Zhuji Dan. The effect of this Tsukidan can improve the success rate of foundation building. In fact, this Zhuji Dan is not exclusive to the Five Immortal Palace, and when the disciples of various sects build the foundation, they often need to take the Zhuji Dan to help the disciples succeed in building the foundation.

But the special feature of the Five Immortal Palaces is that even if they take the Tsukidan, their success rate of building the foundation is about the same as that of the disciples of other sects when they have never taken the Tsukidan, which is pitifully low. For example, in a normal sect, when you don't take the Tsukidan, maybe one or two out of a hundred disciples succeed in building the foundation. And after taking the Tsukidan, out of a hundred disciples, maybe four or five of them succeeded in building the foundation. And the disciples of the Five Immortal Palace, if they don't take the Zhuji Dan, there may be a hundred disciples, and none of them succeed in building the foundation, and if they take the Zhuji Dan, the situation is not necessarily any better, and among the hundred disciples, there may be one or two who succeed in building the foundation.

Such a low success rate of foundation building is obviously extremely detrimental to the continuation of the Five Immortal Palace. But the Five Immortal Palaces were very helpless about this, and there was no way to fundamentally solve the problem of the disciple's foundation building rate being too low. Moreover, if this foundation building is not successful, the cultivation will be greatly reduced, and the cultivation will generally be reduced to one level, from the completion of Qi refining to the ninth layer of Qi refining. If you want to build a foundation again, you have to re-cultivate to the perfection of Qi refining, which often takes a long time.

There was no way, so the Five Immortal Palace had no choice but to take a few more Zhuji Dan when each disciple was building a foundation to increase the chance of building a foundation. Therefore, the disciples of the Five Immortal Palaces often take two or three Zhuji Dan together before going to the Five Immortals Blessed Land to build a foundation. Even so, the foundation building rate is not very high, and only four or five out of 100 people have successfully built the foundation. Of course, if each person takes five or six Tsukidans together, the chances of building a foundation will definitely increase greatly. But this Zhuji Dan is not so easy to obtain, no one knows this Zhuji Dan Dan recipe and refining method, and they can't refine it themselves, so they can only buy it from the Immortal Cultivation Sect. And this Tsukidan, the price is frighteningly expensive, and the Five Immortals Palace simply doesn't have that kind of strength to buy so many Tsukidan.

Nie Fei read all the lessons learned, and there was an understanding in his mind. This foundation building is indeed extremely difficult, and it is often out of a hundred people that only three or four people can succeed. It is no wonder that the immortal cultivators in the foundation building period are pitifully few compared to the immortal cultivators in the qi refining period, and the probability of foundation building is so low. In addition, Nie Fei also knew why there was such a big gap between the two realms in the foundation building period and the qi refining period. It turns out that after the foundation is built, the aura in the body will be more refined, and the power of the exercises used will also increase by a hundredfold. It can be said that the gap between these two realms is simply one heaven and one underground.

Nie Fei sometimes thought that he had the strength to fight with the monks of the foundation building period by relying on his ice spirit, but looking at it this way, he was too naïve. It is true that he may not lose to the foundation building period monk in terms of cold qi, but the gap in spiritual qi is too large, and he has no ability to fight at all. Ever since he read this experience, he couldn't help but put away his contempt, and at the same time, he also paid unprecedented attention to the restrictions on the realm of cultivating immortals.

Although this experience did not help Nie Fei substantially, it could be regarded as a preliminary understanding of Nie Fei's foundation building. Nie Fei thought to himself: Now that he is at the sixth level of qi refining, there is still a distance from the completion of qi refining. However, if the problem of the failure of the spiritual herb liquid is solved, this distance is actually not too far, and it is completely possible to raise the spiritual energy to the perfection of qi refining within a month. At that time, the matter of building the foundation became an urgent matter. Therefore, this foundation building is actually not far away, and it is the right time to make plans at this time.

To Nie Fei's surprise, it turned out that there was also the term Zhuji Dan. Looking at the meaning of the experience, it seems that the more Tsukidan is taken at one time, the higher the success rate of this Tsuki. "Since external forces can help, then in the future, I will try to get more Tsukidan. Nie Fei couldn't help but think.

But after a while, Nie Fei sighed softly again. The idea of building a foundation is good, but in his current situation, it is not the most important thing, and the most important thing is to solve the problem of the failure of the Spiritual Solution. If this problem is not solved, it will be empty talk. Unfortunately, he hasn't made any progress so far.

......

Nie Fei shook his head, no longer thinking about the matter of the spiritual herb liquid, and picked up the jade slip again.

In this jade slip, it is recorded that an ancestor of the Five Immortal Palaces has an edict, and it is an order to all disciples not to delay the moment of entering the Fire Demon Valley. In addition, it was probably this patriarch, in order to inspire the various disciples, faintly revealing a hint of the purpose of going to the Fire Demon Valley. It seems that the disciples of the Fire Demon Valley for generations, after countless trips to the Fire Demon Valley, found that there is a mystery hidden in the Fire Demon, and if this mystery is solved, it can solve the problem of the low probability of the disciples of the Five Immortal Palace building a foundation.

Nie Fei couldn't help but suddenly realize, no wonder the Five Immortal Palace made such a big effort, and also sent four elders from the foundation building period into the Fire Demon Valley, it turned out to be for this. Nie Fei secretly thought: If the Five Immortal Palaces can really solve this major matter through this trip to the Fire Demon Valley, no matter how hard they exert their efforts, it will not be in vain.

In addition, the patriarch of the Five Immortal Palaces also said that there was another purpose for entering the valley this time, that is, in the Fire Demon Valley, there were a very large number of fierce beasts called Fire Feather Beasts. The adult Fire Feather Beast is a mid-level fierce beast, which is equivalent to the cultivation of the ** layer of Qi refining of an immortal cultivator. There are even some ancient Fire Feather Beasts that have advanced to the Upper Order Fierce Beasts, which are equivalent to the cultivation of immortal cultivators in the Qi refining perfection and even in the foundation building period.

In the body of this fierce beast, there is a Neidan. This inner pill is toxic, and it is generally second-class, intermediate to upper-level. This inner pill is the best material for the cultivation of poison in the Five Immortal Palace. Therefore, another purpose of the Five Immortal Palace's entry into the valley this time was to hunt and kill this beast and take its inner pill for cultivation of poison skills.
