Next to Haoyue Lake, more than ten miles away from Xiangyang City, Ling Feng sat in a hidden cave, and after most of the day of recuperation, the cracks on his body had basically disappeared.

But gradually, he discovers the strange place in this cave.

In addition to isolating all sounds from the outside world, the aura in this cave was stronger than the outside world, especially where he was sitting now, the aura was more than ten times stronger than the outside world.

If you feel it carefully, it is not difficult to find that this rich aura comes from the underground.

Ling Feng knocked on where he was sitting, his voice was thick and deep, obviously it was not hollow underneath, but this made Ling Feng even more strange.

"Could it be that there is any mechanism?" Ling Feng was looking around at the moment, and suddenly felt a bulge near the corner of the wall, and subconsciously pressed it, and immediately Ling Feng felt a whirlwind of the sky, and after that, he found himself in a stone house.

The concentration of aura here is even richer than outside, and even the existence of aura can be seen with the naked eye, and every wisp of aura is very pure.

"It turned out to be a spirit room. "Ling Feng had seen this kind of stone chamber before, but he hadn't seen much of it now.

You must know that more than a hundred years ago, if a certain family could occupy a spirit room, then this family could become a giant in a short time.

Because at that time, in addition to the use of spirit stones, there was only enough spiritual energy in the spirit room for martial artists to cultivate, and compared with spirit stones, the cost of using the spirit room was much smaller.

Because underneath the spirit chamber is a spiritual vein, which can provide a large amount of pure aura.

But now, because the aura of heaven and earth is already very strong, the role of the spirit room is much smaller.

Moreover, using a spiritual vein to make a spiritual chamber is a helpless move, after all, the spiritual energy in a spiritual vein is limited, and the coverage is large, and the period of use is short.

In addition, under the nourishment of the rich aura of these spiritual veins, a larger, even super spiritual vein, has been formed, and such spiritual veins are not something that ordinary people can touch.

However, no matter what period it is, the spiritual vein has its irreplaceable role.

Because, the aura in the spiritual vein is different from the spiritual stone aura.

The aura in the spiritual veins is the purest aura in heaven and earth, and it has been filtered through the layers of the earth, and the impurities in it are so small that they can almost be ignored.

Therefore, it can not only improve people's cultivation like ordinary aura, but also play a role in washing the body after a long period of absorption.

This kind of washing is different from the refining of the body in the realm of earth martial arts.

Although the refining of the body in the Earth Martial Realm will quickly and massively remove impurities from the body, the deeper impurities cannot be refined in this way, while the aura in the spiritual veins can.

It is because it is very pure, so pure that it almost does not contain any impurities, and when it shuttles through the human body, some impurities will melt into it and then be excreted from the body.

Moreover, compared with the tempering of the Earth Martial Realm, this tempering is more gentle and more thorough.

If the tempering of the body in the Earth Martial Realm is compared to a storm, then the washing of the spiritual veins is a drizzle.

Although the storm is very violent and can wet the ground in an instant, after the rain has passed, when you dig up the ground, you will see that there are still some parts of the ground dry.

Although the drizzle is small, it takes a long time to wet the ground, but it reaches several meters underground.

Of course, the latter takes a long time, there is no doubt about it.

Some people may say that a little impurity will not affect the breakthrough of cultivation and one's own strength, and there is not much difference between washing it away and keeping it.

Is that also the case?

If someone asked Ling Feng this question, then he would get Ling Feng's affirmative answer.

No, of course not!

It is true that the deeper impurities will not affect the breakthrough of the cultivation of the Earth Martial Realm and the exertion of strength, but its existence will directly affect the time for the Earth Martial to break through the Heavenly Martial Realm.

There are even many people who ignore the existence of these impurities and stop at the ground martial arts all their lives.

Of course, the reason why Ling Feng knew so much was mainly because he had looked at the collections in the Heavenly Wind City Scripture Pavilion, which were the crystallization of tens of thousands of years of human beings, and he had a detailed introduction to almost every realm.

However, knowing is knowing, some things will not change just because they know, if he hadn't touched this spirit room, Ling Feng could only choose other ways to clear the deep impurities in his body.

It's just that it will be more troublesome, and it is not as straightforward, easy and simple as using the spirit chamber.

Therefore, this discovery made Ling Feng very happy, he had just met the golden carp that had quickly broken through the Earth Martial Arts, and now even the spiritual veins that had broken through the shackles of the Heavenly Martial Arts had appeared.

It's just that he can't figure out why there is such a spirit room in this place, after all, the existence of the spirit room means that there is a spirit vein underneath.

And the value of a spiritual vein for any family or sect is immeasurable, after all, with it, the probability of breaking through the Heavenly Martial Arts will be greatly increased.

The reason why the Xia, Zhao, Wang, and Zhang families were able to become the four major families of Xiangyang City was because the four families had a Tianwu Realm martial artist in charge.

Just a martial artist of the Heavenly Martial Realm has allowed them to sit firmly in the position of the four major families of Xiangyang City for decades, so if it is ten, a hundred, what kind of situation is it......

Compared to the value of the spirit vein, Ling Feng was even more surprised by the terrifying ability of the original owner of this spirit room.

You must know that although the spiritual vein is not a living thing, it is not a dead thing, it has spirituality, and drawing spiritual energy from its body is like trying to extract blood from the body of a demon beast.

Therefore, it will not willingly let people extract its own strength, and it will resist like a demon beast.

And if you want the spirit vein to be used by people, you must first subdue it.

But the spiritual vein is a thing conceived by heaven and earth, and it is very supernatural, even if it is the smallest spiritual vein, its power is not something that human beings can compete with.

Ling Feng didn't know how this Spirit Room Master did it, but one thing was for sure, that is, the strength of this Spirit Room Master was probably the most terrifying of the people he had ever seen.

"I don't know if this senior has left anything behind. Thinking of this, Ling Feng's eyes lit up, and he immediately searched for it in the stone house.

Suddenly, it was as if he had touched another mechanism, and then the wall in front of him began to become illusory, eventually turning into a black hole.

Ling Feng's eyes lit up, and he cautiously approached the entrance of the cave.

However, he did not rush in, but wandered around the entrance of the cave for a while, picked up the stone pier next to it and threw it into the black hole, and only after making sure that there was no danger did he walk inside.

The cave is also a stone room, but it is more like a storage room, and there are many bottles and jars in it, but most of them are broken, only two or three bottles are still intact and capped.

Ling Feng walked to the front of these bottles, picked them up and shook them gently, immediately making a crisp collision sound, and then he gently opened the caps of the bottles, and suddenly a strange fragrance wafted out.

"This is ......" Ling Feng seemed to have guessed something, and immediately poured out the contents of the bottle.

This is a dragon's eye laughing pill, and there is a faint glow on it.

Then, he immediately put the pill back into the bottle and closed the cap.

"It seems that this senior should be an alchemist, and this pill should be an elixir refined by an alchemist. Ling Feng said with some excitement.

Alchemists are a very special profession, they are able to refine powerful elixirs with different functions.

It's just that more than a few hundred years ago, with the lack of spiritual energy, all kinds of medicinal herbs gradually became extinct, and the alchemists gradually faded out of people's sight because they had no medicine to refine.

Also, the inheritance of the alchemist is generally an oral transmission of heart techniques, so even in the Hidden Gold Pavilion of the Heavenly Wind City, the holy land of martial arts, there is not much introduction to this.

And after confirming the identity of this person, Ling Feng's mood became even more excited.

If you can get the inheritance of the alchemist, then with the assistance of the pill in your cultivation in the future, the effect will be even better.
