The reason why Li Feng took a fancy to this Phantom Mystery Technique was because this Phantom Mystery Trace Technique was very different in cultivation. Pen, fun, pavilion www. biquge。 info

When cultivating other kinds of exercises, as long as you are diligent in cultivating and use them more often, your power will increase. To put it bluntly, practice makes perfect, and the more you practice, the more proficient you become.

This cultivation method is actually the right way to cultivate all exercises, and it is also in line with the heavenly way that only after giving is rewarded.

It's not that Li Feng doesn't want to practice the exercises according to this method, but there is something about this method that Li Feng can't accept, that is, if he cultivates according to this method, it will definitely delay for a long time before Li Feng can practice the exercises well.

However, the time when Ning Tao came to Li Feng was imminent, and Li Feng really didn't have the time to study the exercises in detail.

The Phantom Trace technique is different. It is written in detail on this exercise that if you want to practice this exercise well, you need to practice diligently and hard, and you will have to pay great hardship, and these will not play any role at all.

Only by taking an elixir called the Earth Soul Pill can this technique continue to be deepened.

It turns out that the most important part of this exercise lies in the cultivator's use of the Five Elements of the Middle Earth. This requires the immortal cultivator to have the aura of the earth in his body, so that he can use the earth line.

The Earth Soul Pill is the elixir that enhances the aura of the cultivators.

......

Li Feng thought about it carefully, practicing this Phantom Trace Technique was undoubtedly the best choice.

But there is a prerequisite in this, that is, he must successfully refine the Earth Soul Pill.

Regarding the refining of the Earth Soul Pill, Li Feng was full of confidence after successfully refining the Muscle Generating Pill and Qi Refining Pill. He believed that he would definitely be able to successfully refine the Earth Soul Pill.

"As long as I refine the Phantom Trace Technique, Ning Tao and the like will not be a problem at all. Whatever you say, I will also refine the Earth Soul Pill. ”

After Li Feng made up his mind, he wrote down the formula of the Earth Soul Pill in the exercises, and then went to the Secret Law Valley to buy medicinal herbs.

......

Li Feng came to the Secret Law Valley again.

To refine the Earth Soul Pill, a total of three herbs are required. Li Feng thought that since they were all herbs for refining the same elixir, they should be able to buy them in one pharmacy.

Who knows, things are not what he imagined.

Under his inquiry, the three herbs were bought in three different pharmacies.

Moreover, Li Feng also discovered a very interesting phenomenon. A herb that is sold in one pharmacy can no longer be purchased in another pharmacy.

Each of the apothecaries in this Secret Magic Valley has its own monopoly on a number of medicinal herbs.

This way of doing business is undoubtedly of great benefit to sellers, but it is not a good thing for buyers.

Li Feng realized that there must be a powerful force at work here. According to his past experience, whenever there is a monopoly, it is somewhat related to power.

What is the secret in this, Li Feng didn't have the time to delve into it, his purpose was only to buy the three herbs for refining the Earth Soul Pill.

Things are really as he thought, once the pharmacy monopolizes all kinds of herbs, the price will be decided by themselves, of course, it is only high and not low.

Each of these three herbs is very expensive. Li Feng spent nearly three hundred spirit stones on his body to barely buy the amount of medicine to refine two Earth Soul Pills.

Li Feng had previously sold a muscle-building pill and earned five hundred spirit stones. Five hundred spirit stones is not a small amount.

But I didn't expect that I only came to the Secret Law Valley twice, bought some medicinal herbs, and consumed all the five hundred spirit stones.

It was only at this time that Li Feng profoundly realized how difficult it was to cultivate immortals.

There are various realms that need to be broken through, and each realm is like a mountain, and climbing it is like climbing to the sky.

Not only that, but the resources for cultivating immortals are also a big problem. If there are not enough resources for cultivating immortals, the road of cultivating immortals is bound to not go far.

......

After returning to his residence, Li Feng couldn't wait to refine the Earth Soul Pill according to the previous method.

In the beginning, everything went smoothly.

It didn't take half an hour for Li Feng to find several temperatures of the Earth Soul Pill reaction.

Subsequently, Li Feng injected spiritual energy into each reaction solution, and there was a bottle of reaction liquid, which was a medicinal liquid that reacted at fifty degrees, absorbing the most spiritual energy. There is no doubt that this bottle is the active ingredient of the Earth Soul Pill.

Up to this point, it went surprisingly well.

However, at the end of the day, something unexpected happened.

In the past, when Li Feng was refining the active ingredients of the Muscle Pills and Qi Refining Pills, after injecting the aura, the active ingredients of the two pills would be separated from the rest of the impurities in the liquid medicine, the upper layer was the active ingredients, and the lower layer was the impurities.

In this way, as long as Li Feng removed those impurities, he could extract the very pure active ingredients of the two pills.

However, when refining this Earth Soul Pill, the active ingredients of the Earth Soul Pill were always mixed with impurities and were not layered at all.

At the beginning, Li Feng thought that there was not enough time, and he only needed to wait for a certain amount of time, and the impurities and active ingredients would be separated.

Half a day passed, and the impurities and active ingredients of the bottle of liquid medicine were still mixed together, without a trace of delamination.

"This time, it seems that we can't refine the active ingredients of the Earth Soul Pill that are very pure. Li Feng thought to himself.

Li Feng is not a perfectionist, he will not force himself, he has to extract pure active ingredients.

However, there was one thing that Li Feng had to consider, these active ingredients, mixed with impurities, would inevitably affect the medicinal effect of the Earth Soul Pill, and would reduce the medicinal effect of the Earth Soul Pill a lot.

Li Feng thought about it for a while, this kind of liquid medicine mixed together made the active ingredients separated, and when he made poison in his previous life, there were many methods that could be used for reference.

For example, distillation, chemical method, and so on.

With all these methods, Li Feng believed, there would definitely be a method that would be suitable for this mixture of medicinal liquids of the Earth Soul Pill.

As for what kind of method works, Li Feng is still not sure, and he has to try one by one to know.

However, the current situation does not allow Li Feng to carry out this work at all. Obviously, this is a waste of time, and if you are lucky, you may be able to separate the impurities from the active ingredient as the first method you try.

If you are unlucky, try one method at a time, maybe before you can successfully separate, Ning Tao has already found it.

Li Feng thought about it carefully again, and made a decisive decision to wait until Ning Tao's matter was resolved.

As for the impurity of the Earth Soul Pill, it's a big deal that one has no effect, and one more one is enough.

......

At that moment, Li Feng refined all the raw materials of the Earth Soul Pill into a mixed medicinal liquid, refining a total of eight bottles of medicinal liquid.

Li Feng evaporated three of the bottles to remove the water and kneaded them into pills. For the other five bottles, Li Feng also had to use them for separation tests, so he kept them for later use.

With three bottles of liquid medicine, Li Feng kneaded a total of nine pills.

After everything was taken care of, Li Feng went to look at the spirit beast again.
