Lu Chengfeng continued to walk inside along the passage, the further he went, the higher the concentration of heaven and earth aura, and even Lu Chengfeng had already discovered the existence of liquid aura, and this kind of aura would only be formed after the concentration of aura reached an extremely high level.

Compared to ordinary aura, even if it is rich, it is not as strong as this spiritual liquid, which is more conducive to cultivation.

Even the spiritual liquid has appeared now, so I am afraid that it will not be too far from the real location of the spiritual vein, although it is said that in this world it is dominated by leisure civilization, but the spiritual stone is still an extremely scarce cultivation resource.

In this world, spirit stones occupy a very important position, just like oil on the earth. Perhaps it is because the discovery and mining technology of spiritual veins in this world is very immature, so the spirit stones in the entire world are relatively scarce so far.

And Lu Chengfeng looked at the richness of the aura of heaven and earth here, at least it could be used by hundreds of people to practice, and if this entire spiritual vein was added, I am afraid that thousands of people would be fine, or even tens of thousands.

Such a spiritual vein is a huge wealth for any cultivation sect or secular dynasty, but now this huge wealth has been made rich by Lu Chengfeng alone.

It's just that what makes Lu Chengfeng a little puzzled is that such a huge spiritual vein exists in the depths of Jinling City, but no one has developed it on a large scale for so many years, or except for a very few people, no one else has discovered it here.

Maybe the land immortals of the Jindan Realm have developed this place to a certain extent before, after all, it is a very small number of people, or only the person who built this place knows, and Lu Chengfeng is probably the second person to come to this place.

After doing this for a long time, Lu Chengfeng found that the road in front of him had collapsed, but it was also in this place that a lot of light shone in, and at the same time, an extremely rich heaven and earth aura poured out from this place.

And the collapse of this place is obviously due to external forces, either due to water accumulation, earthquakes, or man-made reasons.

Moreover, this place is very close to the ground and Lu Chengfeng's first judgment may be because of the topography. A large amount of water collects in this place, causing great pressure, and the passage itself makes the rock structure more fragile here, so the rock layer above this passage will not be able to withstand it and break.

However, Lu Chengfeng found a very small crack in the place where he was now, which was just enough to lead inside, but it could only allow one person to pass sideways, which was because Lu Chengfeng was very thin, if he changed to a slightly fatter person, I am afraid he would not be able to get by.

The closer he got inside, the more majestic the aura of heaven and earth that Lu Chengfeng felt, and there were condensed water droplets on these stone walls, and these water droplets were all spiritual liquids formed by the condensation of spiritual energy, and then flowed along the ground along those stone walls.

"It's really a tyrannical thing! How many cultivators' coveted spiritual fluid is flowing on the ground like wastewater......

Not to mention Lu Chengfeng, he is now a great cultivator of the Foundation Building Realm, even if it is other cultivators, if he is in Lu Chengfeng's current situation, I am afraid that he will be even more heartbroken than Lu Chengfeng.

Lu Chengfeng was almost in a very excited state throughout the whole process, although he was already a person who had traveled through the sea of stars, but compared to the sea of stars that seemed a little ethereal, but it was just a brilliant moment, these things in front of him were more real.

This is like holding a bank card with 100 million yuan in his hand, which is far less impactful than putting 100 million yuan in front of him.

And gradually, Lu Chengfeng has found relatively mixed spirit stone crystals on the stone wall of this exercise, although there are still many impurities in it, but at least it means that this place has reached the periphery of the spirit vein.

Moreover, the natural spiritual veins are not completely immersed, and they still need to be artificially refined to reach the point where the cultivator can use them, although it is said that the cultivator can also directly absorb the spiritual energy in these spiritual stones, but it is too complicated, not only the cultivation speed is extremely slow, but the danger factor will also be greatly increased.

And from this place, the sky looks like a ray of sky, and on top of the steep cracked stone wall, there are still some ferns growing here and there.

And the entire deep underground is the brightest time only when the sun shines directly into the sky, and as the sun rises in the east and sets in the west, the bottom of this rift valley where Lu Chengfeng is located will become darker and darker.

As Lu Chengfeng walked deeper and further, the purity of those spirit stones became higher and higher, and seeing this original spiritual vein, Lu Chengfeng became even more excited.

Although this spiritual vein seems to be quite large-scale, it is extremely difficult to develop on a large scale due to its deep underground, perhaps the Jindan Immortals who didn't discover this place back then were also based on this reason, so there was no big deal, so let's search for spirit stones here!

Instead, some buildings were built directly here, including a place to live, but this place was not suitable for long-term living, and even dervishes did not want to live in places where they did not see the light of day almost all year round.

This is almost equivalent to exile, but the only difference from exile is that there is a huge spiritual vein here, which can allow people to practice for thousands of miles in a day and quickly improve their cultivation realm.

And for the current Lu Chengfeng, such a huge spiritual vein is actually not as good as the night pearl on the wall he encountered before, at least the pure aura in those night pearls has been refined and purified by a land immortal at the level of a Jindan immortal, and it can be said that it is twice the result with half the effort when used for cultivation, and it is also extremely easy to carry.

But this huge spiritual vein is different, unless Lu Chengfeng stays here for a long time, otherwise it will be difficult for him to transport a large number of spirit stones to the outside world by himself.

"What a happy trouble!"

Lu Chengfeng was about to go crazy with laughter, and the terrible laughter echoing in the depths of this younger brother seemed very ethereal and long, especially that there were many, many echoes.

Lu Chengfeng not only sighed that the world is really impermanent!

He was hunted down by great cultivators before, but now he not only stepped into the realm of foundation building, but also discovered such a huge spiritual vein, but such a huge wealth, he couldn't completely swallow it alone.

In that place, Lu Chengfeng suddenly had the idea of establishing a sect, since he could not swallow such a huge spiritual vein alone, he could establish a sect to cultivate his own people.

At least the forces he has cultivated are trustworthy, although it is said that Lu Chengfeng is now in a high position in the Great Liang Dynasty and holds great power, but it is not a force that he can really control after all.

Although he is now half in control of the Privy Council. But in fact, the real boss behind it is His Majesty the Emperor, and whether it is the Tiger Guard or the Wolf Guard under the jurisdiction of the Privy Council, no matter how it is said, it belongs to the army of the Great Liang Dynasty, and it belongs to the public, not his own.

Although the secular dynasties of this era are dominated by the family and the world, the development of the entire dynasty in modern times is no longer something that the emperor can say alone, and the emperor cannot truly monopolize power and hegemony.

Whether it was Beigulou, the world's No. 1 intelligence organization, or Qianshan Pavilion, the world's No. 1 killer organization, that he encountered before, they were all existences that could affect the overall situation of the world, and even competed with the imperial court to a certain extent.

For the first time, Lu Chengfeng experienced the dual contradiction of slow and fast cultivation, although in normal times, he relied on the Heaven Swallowing Technique, and the speed of his cultivation was far higher than that of other cultivators, in the depths of the earth, the majestic and rich aura of heaven and earth had already been in short supply.

Compared with the past, Lu Chengfeng's current cultivation can be described as a thousand miles a day, but compared to the majestic heaven and earth aura here, Lu Chengfeng's speed is really like an ant, even if he consumes a lot of heaven and earth aura, it has almost no impact on this place.

Lu Chengfeng knew very well that once he really started a sect, this place could only be used as a cultivation place for elite disciples, and it could not be developed on a large scale to supply all the disciples under his sect, at least with the current mining technology, it would not be able to reach that level.

If this world can reach the scientific and technological level of the earth where Lu Chengfeng was before, it is easy to mine such a deep spiritual vein, but for this feudal society with extremely low productivity, it is tantamount to a fool's dream, even if it is a land immortal in the realm of Jindan, it is impossible to act as a coolie to mine here day and night.

In particular, the geological structure of this place is very complex, not only many places are dominated by sedimentary rocks, but also there is a huge underground river, maybe once the mining is overdone or the defense measures are not done well, I am afraid that the entire Lingmai mine will collapse again, or even cause underground river water to backflow.

Moreover, there is another point that this place is very close to Jinling City, and there are many great cultivators in Jinling City, and there are even some Emperor His Majesty of the Jindan Realm.

Once the excessively rich heaven and earth aura in this place leaks out, it will inevitably attract the attention of a large number of cultivators, and at that time, this place will definitely be exposed in front of the eyes of the world.

At that time, this place will definitely be unavoidable, causing a multi-party force to compete, and then it will be followed by large-scale non-standard mining, although it may be half the effort, and a lot of manpower and material resources will be consumed to obtain a very small number of spirit stones, but it will not be able to resist the desire in the hearts of cultivators.

Compared to the desires of ordinary people, the desires of cultivators with more powerful powers are even more terrifying.

Comparatively speaking, most of the cultivators have greatly improved their strength. However, the depth and realm of his thoughts have not been improved accordingly, so there are many hidden dangers for the future.

Although many practitioners pay attention to cultivating the Dao mind on the path of cultivation, how many of them can truly do it?
