In Nie Fei's hand, there happened to be a Fire Feather Beast's Inner Dan, which was the contents of the Wood Spotted Storage Bag. Nie Fei pinched the inner pill in his hand, and thought to himself: It turns out that this pill is also very important to the Five Immortals Palace. The second-level intermediate level, the toxicity is the same as the spirit relief grass, so why not replace the five immortal palaces with the spirit relief grass?

Although Nie Fei didn't understand this question, he faintly guessed. Suddenly, he seemed to have grasped something in his heart.

In the end, Nie Fei held the jade box in his hand again and opened it. As soon as the jade box was opened, a fresh fragrance of herbs suddenly came to my nose. Smelling this fragrance, I don't know if it's a psychological effect, Nie Feiden felt refreshed and indescribable.

Nie Fei opened his eyes and looked into the jade box, only to see a piece of green velvet spread in the jade box, with four small characters on it, which read: "Building the foundation of the elixir." "A pearl-like elixir was placed in the middle of the jade box, exuding bursts of medicinal fragrance.

"This ...... Is this the Zhuji Dan?" Nie Fei looked at the pill, and his heart was extremely excited. He was thinking about getting some Tsukidan, but he didn't expect that Mu Zhuozi had such a hidden one in his storage bag, and it was not easy to get it. After a while, Nie Fei recovered from his excitement, covered the lid of the jade box, and properly stored the Tsukidan in the storage bag, thinking to himself: This Tsukidan is not helpful, and I will need to get a few more in the future.

......

By now, Nie Fei had inspected all the foreign items. There are so many items, useful ones, and of course some unused. However, these items, after all, were obtained for nothing, how could Nie Fei ask for too much for fat and thin?

At the same time, Nie Fei also had a deeper understanding of the matter of killing people and snatching treasures, and the reason was that it was too easy to kill people and seize treasures to obtain immortal cultivation items. For example, Nie Fei spent nearly 30,000 spirit stones to buy only three treasures, which can be described as a huge cost. And he killed Mu Zhuozi and Mu Madara, and it didn't take much effort, but the harvest was so great. Compared with the two, it is obviously more affordable to kill people and seize treasures. In this way, it is easy to understand why the matter of killing people and snatching treasures often happens in the world of cultivating immortals.

But in the same way, the cost of killing people and looting treasures is small, but the risks are very high. Of course, this kind of risk is not moral, it is normal for the weak to eat the strong in the immortal cultivation world, and the strong kill the weak. This risk comes from two main sources. First of all, if you can't figure out the cultivation of the person who wants to kill and grab the treasure, it is likely to be counter-killed, such as Mu Zhuozi and Mu Madara, which will cost you your life. Second, if it is the object of murder and treasure grabbing, with a deep background, and he is killed rashly, the treasure is snatched, and maybe the other party's division commander will come to seek revenge, so that his life is not guaranteed.

Therefore, this murder and treasure grabbing looks refreshing, but it is actually dancing on the tip of a knife, and it is difficult to guarantee that you will lose your life at any time.

Thinking of this, Nie Fei couldn't help but wonder: I don't know how their master would react if he killed Mu Banzi and Mu Zhuozi, and whether he would find his head.

But then, Nie Fei thought again: Worrying about these things now is not just worrying too much, it is useless. First of all, the other party wanted to rob his treasure, and he did not take the initiative to provoke the other party, at that time, if he did not kill the other party, he would be killed by the other party, and he had a sufficient advantage in principle. Of course, the other party's division commander, if he comes to the door, is likely not to reason with him. Then, as long as you do one, that is to do your best to improve your cultivation, and even if the other party's teacher is unreasonable, then you will see the level of the exercises.

Whoever has a hard fist is the truth. This is this immortal cultivation realm, a simple and dark law.

......

Cultivation is now the most urgent thing for Nie Fei. However, in order to improve this cultivation, it is obviously not realistic to absorb the spiritual energy over time, so the most important thing is to solve the problem of the failure of the spiritual liquid of the spiritual herb.

Nie Fei had also thought about treating the Jie Ling Herbal Liquid as a contemporary antibiotic such as penicillin, and changing its internal structure to solve the problem of drug resistance of the Xie Ling Herbal Liquid.

However, in this world, Nie Fei had no means of analysis, and there was no way to detect what the structure of the Spiritual Herb Liquid was. Based on this concept, we can continue to try to add various materials to the Spiritual Solution, in the hope of being able to react with the Spiritual Solution, to obtain a new substance. This substance not only has the aura in the Spiritual Solution, but also makes the resistance of the Spiritual Liquid disappear.

This is Nie Fei's ultimate goal, but this goal is not easy to achieve, so he can only add one substance to the Spiritual Relief Herbal Liquid one substance, and then look at the results.

Therefore, Nie Fei didn't have any skills to speak of this solution, just like there is a way to crack the code in contemporary times, he kept trying, maybe he would happen to run into it. This method is purely a form of violence, and there is no beauty in it. But with the current conditions alone, Nie Fei can only take this way, and there is really no other good way.

But today, Nie Fei's distress for many days seems to have found a solution.

This is due to the jade plate with poison inscription written on it that Nie Fei obtained, and the Fire Feather Beast Neidan that he inadvertently obtained. Through the jade plate, Nie Fei learned that the Fire Feather Beast Neidan and the Jie Ling Grass were both second-level and medium-sized poisons. So, is there some connection between them? Just two poisons are poisons of the same order, and the relationship between them is very subtle.

Another thing that caught Nie Fei's attention was that since the two kinds of poisons were poisons of the same level, why didn't the Five Immortal Palaces practice poison skills and not use the spirit relief grass, which was extremely widely distributed and very convenient to cultivate and purchase, to cultivate and cultivate poison skills? Instead, they had to go to the Fire Demon Valley to hunt down the fierce beast called the Fire Feather Beast and use its inner pill to cultivate the poison skill? Isn't this a kind of behavior that is difficult for people to understand.

Nie Fei thought that he could think of it, and others who were not stupid could also think of it. The people of the Five Elements Palace make a living by cultivating poisonous skills, and the various joints in it have naturally been thoroughly studied for a long time. They don't need to solve the spirit grass, it must be that the spirit grass is not available. Then why is the Spiritual Relief Grass not usable? Is the Spiritual Relief Grass too poisonous and not suitable for use? Or is the toxicity of the Spiritual Relief Grass different and not suitable for cultivating poisonous skills?

Nie Fei believes that the above two reasons are possible, but they are unlikely. Nie Fei couldn't help but guess in his heart that in fact, the reason why the people in the Five Elements Palace didn't use the Spirit Solving Grass was not that they didn't use it, but that they used it too much and too indiscriminately, resulting in drug resistance.
