Li Feng took the half bottle of clear liquid and gently took a small sip. Pen "Fun" Pavilion www.biquge.info

As soon as this small mouthful of clear liquid entered his abdomen, Li Feng felt a burst of breath be generated in his abdomen, rushing straight towards the sea of qi.

This kind of feeling, Li Feng is very familiar, it is the breath of the earth's aura. It's just that this aura is very different from the aura of the earthy aura that Li Feng absorbed before, and it has to be integrated into the sea of qi more quickly than before.

Li Feng had to sit down cross-legged to absorb this earthy aura.

Two hours later, Li Feng had absorbed this earthy aura, and in the sea of qi, the earthy aura had increased a lot.

It's just that with this small sip of the medicinal liquid, the amount of earth-moving spiritual energy increases, which is comparable to the entire bottle of medicinal liquid before.

This further illustrates that the active ingredient of the Earth Soul Pill is in the clear liquid.

Li Feng took the half bottle of clear liquid in his hand, raised his head, and drank half a bottle of clear liquid cleanly.

......

After two days passed, Li Feng completely absorbed the earthy aura in this half bottle of clear liquid, and all of it was turned into earthy aura and stored in the sea of his qi.

The earth spirit in the sea of qi is steaming and majestic. This half bottle of clear liquid is more than the kind of mixed liquid that Li Feng drinks, and the hundred bottles absorb more earth-walking spiritual energy.

This caught Li Feng by surprise. Who would have thought that it was only half a bottle of clear liquid, and the active ingredients in it were limited, how could it be compared with the active ingredients of 100 bottles of mixed liquid.

Obviously, things cannot be calculated simply by this amount.

Li Feng realized that it must be that in the half bottle of clear liquid, the active ingredients are more refined, so he can absorb more earth-moving aura.

And the mixed medicinal liquid, there were a lot of impurities mixed in it, and those impurities would obviously affect the utilization of the active ingredients of the Earth Soul Pill.

"It seems that the purer the active ingredient, the more amazing the efficiency, and the faster it can be absorbed. ”

Li Feng thought to himself.

Now, Li Feng could conclude that the clear liquid was the active ingredient of the Earth Soul Pill. As for whether it was 100% pure, Li Feng didn't dare to conclude, it was likely that there were some impurities mixed in it. But what Li Feng can conclude is that there must be much less impurities in the clear liquid than before.

It is precisely because there are fewer impurities that the serum has such an amazing effect.

Even if there were still impurities in the clear liquid, Li Feng did not plan to purify it again, and this effect had already made Li Feng very satisfied.

At this moment, Li Feng had never had so much earth-walking aura in the sea of qi, and he didn't know what kind of effect such a profound earth-walking aura would have if he performed the Phantom Trace technique.

Li Feng stepped out and walked into the courtyard. In the sea of qi, the aura of the earth line turned, and the phantom trace technique was cast.

As soon as he used the earthy aura, he suddenly felt bad in his heart. The earth-walking aura, like a flood bursting its banks, frantically gushed out of the sea of qi and acted on the dirt beneath its feet.

Li Feng originally wanted to glide for a distance, which was only between one or two zhang. Who knows, when the earthy aura was stimulated, Li Feng's body suddenly rushed forward, and he felt that everything passed in front of him with a swish.

When he stopped, he found himself outside the courtyard.

Li Feng looked back, and the courtyard wall was more than twenty zhang away behind him. At this time, he slid for a distance of nearly thirty feet, not to mention, even the thick wall, also crossed through. Of course, the wall is also made of earth, which is among the dirt rows, so it can be passed through.

Rao is Li Feng was determined, and after seeing this result, he couldn't help but look at the courtyard wall behind him blankly, opening his mouth and not knowing how to close it.

It took a moment for Li Feng to recover. He only felt that the earth spirit aura in the sea of qi was very sufficient, but where did he think that just such a casual use would have such a miraculous effect.

"It's all because of the purified Earth Soul Pill liquid. Li Feng thought secretly in his heart: "It is precisely because the medicinal liquid is more refined, that the earth spirit aura in the qi sea is very full, and the earth spirit spirit qi will have such an explosive effect." This is the liquid medicine mixed with impurities before, which is far from comparable. ”

After this time, Li Feng finally understood that it turned out that the active ingredients of this Earth Soul Pill were very different from those with impurities and those with purity, and they had the effect of judging like mud.

Compared with the pure liquid medicine, the liquid medicine with impurities is simply garbage, and the amount required to absorb it is large, and the absorption time is also long. Moreover, the efficacy is far less than that of pure liquids.

Li Feng thought again, "Through the medicinal liquid of this Earth Soul Pill, can it be said that in this world, all kinds of pills have the same situation as the Earth Soul Pill." The purer the active ingredient of the elixir, the greater the effectiveness of the elixir. ”

Although this theory has not yet been confirmed, Li Feng feels in his heart that this should be the final conclusion, and it must be correct.

Then, Li Feng performed the Phantom Trace Technique for a while.

At the beginning, Li Feng was very uncomfortable, because the earthy aura in his body, every time he was triggered, it would burst out of the sea of qi, which made it difficult for him to control the distance he could glide on the ground.

However, after practicing for a while, Li Feng finally found the trick to control this explosive earth-moving aura, and every time he swiped, he became freewheeling.

On one of them, Li Feng urged the earth-moving aura in his body with all his strength to test how far he could slide out under the full force.

As a result, in an instant, Li Feng's body appeared fifty zhang away in front of him.

Fifty zhang is the farthest distance that Li Feng can reach this time.

This kind of longest distance actually has nothing to do with the amount of earth-walking aura, but has to do with the explosive power of earth-walking aura.

The amount of earth-walking aura is only related to how long the Phantom Trace Technique can be performed.

Outside Li Feng's residence, there was an empty wasteland, and few people could appear here. Therefore, Li Feng is outside here, and he can experiment to his heart's content.

In less than an hour, Li Feng used this earthy aura in the sea of qi to reach the point where he was at ease.

He stopped and looked ahead. About 30 zhang in front of you is the courtyard wall of your residence.

Suddenly, Li Feng mentioned the earthy aura, and his body turned into an afterimage, and suddenly disappeared in place.

By the time Li Feng's figure reappeared, he was already standing in his courtyard.

The courtyard wall is made of earth, and the aura of the earth can be applied at will, and there is no difficulty in passing through the wall.

Not far in front of Li Feng was the outer wall of the house where he lived. The outer wall is made of solid wood, which belongs to the wood line, and I don't know if the Phantom Trace Technique can pass through.

Li Feng's skills are itchy and he really wants to try it. But in the end, he finally restrained his impulses. Wooden walls belong to the wood line, and the earth line aura may not work. If you can't get through, you're bound to hit the wooden wall hard, and then your head will be broken and bleeding.
