After a while, as the folding space continued to dive, and when it dived to a distance of tens of meters underground, Zhao Xuan's eyes suddenly lit up, and he was overjoyed.

Building!

Dozens of meters underground, he found traces of buildings, buildings piled up of stones buried deep in the ground, not tomb structures, but very ordinary house patterns.

This made Zhao Xuan unhappy.

"Ye Hongji's news is quite reliable, there really are ancient ruins here, a city that has been flooded by the diversion of the river?" At the beginning, Li Jinbiao was digging in the wrong direction by mistake when robbing the tomb nearby, and it seemed to have fallen into an ancient palace, some places are still stone buildings, but some places are also because of the cover of the building, but they are just submerged, and there are certain gaps.

However, digging is wrong, Li Jinbiao still found some good things in that room, and he was even ready to do a lot of work around here, but it's a pity...... I dug around in other places, but most of them were buildings that were filled with dirt and other things, and it was really difficult to find a room that had left a gap before, so I had to give up regrettably.

Now Zhao Xuan is a lot more convenient, the folding space and the normal space are not the same space, he can easily see whether the surrounding is dirt or something else, although if it is all dirt and stone slabs, he can't see through, he can only see a layer near the folding space, but this is enough, after all, he can move at will.

Clearly turning around the building in front of him, Zhao Xuan was slightly excited to find that this architectural style seems to have a lot of similarities in the pre-Qin period. During this time, he studied a lot of ancient knowledge, but he also gained a little in this regard.

"It's really possible, and if this is really the ruins of the hermitage. Although I can't see far from perspective, after all, the scope is determined, as long as I grope around under a large number of buildings, take a walk, more than ten hours, and at my speed, it is enough to walk through a dungeon. ”

A hint of surprise flashed in his eyes, and Zhao Xuan quickly walked forward and backward left and right.

After waiting for a minute or twenty, a hint of surprise flashed again in Zhao Xuan's eyes, who were still underground. The ancient city. The area of this ancient city is really not small, although most of the buildings here are completely buried in the soil, but Zhao Xuan can indeed be sure that this is basically a city in the pre-Qin period.

And it's a metropolis.

This point is also very easy to judge, the pre-Qin period was so backward. It is impossible for an ordinary small city to have so many elegant and high-quality buildings, and there are indeed some of them polished with fine stones. The building of a palatial pavilion attic.

In the pre-Qin period, the metropolis was still located in Qu City, which is indeed very likely.

"It is written on the black gourd. That treasure should be located in a house in Dongcheng District, East ...... "In excitement, he discerned the direction, and Zhao Xuan walked straight to the east side.

………………

Three or four hours later, Qu City, Dongcheng District. Under a prosperous and enthusiastic building is a scene of singing and dancing, but I am afraid that no one would have thought that at this moment, under a ten-storey high-rise building in Dongcheng District, hundreds of meters underground, a figure suddenly let out a whisper of surprise, and then instantly stood on a stone road that was purely constructed of exquisite stone buildings, only two meters high, and could melt one person through.

"Finally found it."

"This underground secret place should be that treasure, it's really good luck, the information collected for the first time is so accurate."

"Thousands of years have passed, and there are still strong fluctuations in the source power of the stars, and this underground killing array is still operating normally? Tsk......"...,

………………

After three or four hours, Zhao Xuan was a little tired from running around underground by relying on the folding space, after all, his whole body cultivation at this time could only support more than ten hours of space folding.

And even if there is a treasure record reminder underground, knowing that things are in Dongcheng District, but he can't affect the real space when he folds the space, he can only rely on his eyes to see, but his eyes can only see a layer at the intersection of space, and the eyes are full of dirt or stone buildings for a few hours, and the direction identification is a big problem, even if he knows that it should be eastward, but there are still many mistakes in the process.

But now that I've finally found it, it's really inspiring.

And before he could penetrate this passage, he felt the fluctuation of the source power of the stars, but he had to know ...... He's still in the folded space at the moment. Space Ancestral Dragon said that he can't affect the real space in the folded space, and the real space can't affect him, but he has to be just a relative situation, and the general situation will not affect him, once there are some special circumstances, this thing doesn't work at all, after all, the strength of the ancestral dragon furnace is too weak at the moment, and there has been a time before when he was beaten by an A-level master with a star weapon and fell into the space, and then there was a time when he encountered a small lock empty stone, and he was shattered as soon as he approached.

Therefore, this kind of inability to affect the ordinary situation that is basically just a reference, once it encounters a master or a treasure with the power of space, it is not suitable, after all, folding space is just a very weak space skill, if this skill is performed by the originator of the power of space, it is estimated that the true god will be difficult to see, but Zhao Xuan himself does not have the slightest power of space, just with the help of the power of the ancestral dragon furnace.

So once you encounter a formation with the power of space, this thing will also be affected.

However, he was only a little surprised, Zhao Xuan didn't continue to care, the formation here is still running, it is not surprising at all, because there is a source crystal mine here.

Back then, a certain nobleman would build a treasure hiding place under a slum house in a civilian area, the main reason was not that it was close to the imperial capital, but that he accidentally found a source crystal mine hundreds of meters deep underground.

The source crystal is the crystallization of the source power of the stars, the thin source power of the stars, which can be integrated into the air formless and substantial, permeating the entire void, some of the blessed land of the immortal mountains with rich source power, and the rich source power can be atomized, liquefied, foggy, and the fairy energy is the same, and the place with the most concentrated source power can be condensed into a solid, which is the source crystal.

The source crystal is divided into upper, middle and lower grades, and there are soul crystals on top of the source crystal.

If a planet is a life, then the source power of the stars is its escaping breath of life, the source crystal is the condensed thing of its flesh and blood, and the soul crystal is indeed the soul of the planet, the soul of the stars.

For earth-level martial artists, medium-grade source crystals can allow them to get terrifying cultivation efficiency, high-grade source crystals are treasures to Tianzun, and cultivation is of great help, and as for soul crystals, in addition to allowing saint-level, supreme, and god-level powerhouses to get a lot of help in cultivation, it is also very beneficial to comprehend the laws of the stars and the laws of the universe.

It's that when Blood Slaughter was at the peak of the gods, he didn't have many top-grade soul crystals in his hands.

Of course, these are the memories of the blood massacre, and the record of the great nobleman of the Shang Dynasty once said that this is a medium-sized medium-grade source crystal vein, he was originally going to secretly dig it out for private ownership, so he bought a house to work day and night, but unfortunately who would have thought that before the source crystal was mined, he encountered that file extinction crisis.

The whole family is in danger, so it is useless to have a treasure, and they gave up mining and transformed this place into a treasure base, and that medium-sized medium-grade source crystal vein is the foundation that supports the operation of the large array, and it is mentioned in the record that if it only supports the operation of the large array, with the scale of that vein, it can be immortal for tens of thousands of years. …,

After all, this is the flesh and blood purification of a living planet, even if it is a medium-grade mineral vein, it is enough to support the rise of a small and medium-sized family. If it was just a formation that was not very terrifying, the consumption would naturally be extremely slow, which was why Zhao Xuan would be so cautious after getting the black gourd. If it weren't for the fact that the gourd had already mentioned this, how could he be so careful?

"Tens of thousands of years of immortality, I don't know how many of these medium-grade source crystals are left, the Shang Dynasty Pangeng period is only more than 3,000 years away from now, is there still a lot of high-grade Yuanjing veins left? If that's the case, it's just that this vein is a batch of priceless treasures, and the high-grade source crystal vein is indeed a great thing. ”

In the slight excitement, Zhao Xuan quickly reined in his emotions, walked out of the folded space, and then calmed down and began to recover his dry cultivation.

But...... After trying it, Zhao Xuan suddenly frowned again and opened his eyes, a trace of strangeness flashed in his eyes.

Void.

The source power here can't absorb it.

"Nima, the stellar source power I cultivated, this is the crystallization of planetary source power, the pure planetary source power crystallization, it can't be used at all, it can't be restored like this, it can't work at all, on the ground, even if it's dark night, you can absorb sporadic stellar source power, but here...... Not a single bit. ”

After thinking about it for a while, Zhao Xuan scolded in a low voice, but no, what he cultivated was pure stellar source power.

And such a pure planetary source power crystal, even if it is very advanced, he can't use it.

As for the alchemy in the past, it was all collected materials from the earth, why could he use it? The reason is very simple, basically nine out of nine of the best elixirs, in the process of growth, in addition to absorbing the vitality of the earth, but also absorbing the vitality of the sun, ninety out of nine materials are bathed in the sun every day to grow.

Zhao Xuan refined into an elixir, others absorbed the planetary source power medicinal properties in the elixir, but what he absorbed was the stellar source power medicinal properties, but a perennial buried underground, pure planetary source power crystallization, and his practice was diametrically opposed.

And this is the source crystal of the earth.

"I should pay attention to this in the future, I haven't paid attention to it before, and I have ignored it." A trace of thought flashed in his eyes, and Zhao Xuan silently looked at the passage that had been extending downward, this dense place was very large, and the surrounding left and right were made of stone slabs several meters thick, making this place a solid underground cage, and Zhao Xuan didn't know how big the enveloping area was for a while.

However, just as Zhao Xuan was thinking, a voice suddenly exploded in Zhao Xuan's ears, directly making Zhao Xuan stunned, and then his color changed.

"Huh, hey, hey, hey, ah, ah, ......"

The direct fluctuations of his thoughts, crisp and gorgeous, echoed in Zhao Xuan's ears, it sounded like the most beautiful movement in the world, but it really made Zhao Xuan change color, how could it be possible, there were people here?!!
