Of course, it was impossible for this Qingyuan City to use spirit crystals to drive the chaotic sky magic array, and even if it was as big as Qingling Mountain, it would be difficult to continuously maintain the magic circle for twelve hours.

Therefore, Chu He deduced that the level of Qingyuan City's chaotic sky magic array was not high, and most of them were driven by mid-to-high-grade spirit stones, and the geomagnetic element force generated could not reach the point of interfering with the teleportation array.

However, even so, if the real person of the Yuan Dan Realm entered it, it would be somewhat affected, and it would be difficult to fly freely. As for the chaotic entry of the Innate Realm or the Qi Refining Realm, most of them are going to make a fool of themselves.

The use of such a chaotic sky array, in this calm place far away from the Demon Cloud Mountain Range, is mostly used to highlight the status of a large city and maintain some necessary order. Even if some spirit stones are wasted, it is a necessary investment.

When it was still more than two hundred zhang away from the city gate, Chu He retracted the clouds and fell down, and walked over slowly. Many monks also reined in here and retreated.

However, there are also some mindless people in the countryside who continue to swagger with magic weapons, wanting to fly over the city gate and enter inside. How do you know that before you get close to the city gate, it is stirred by the powerful geomagnetic elemental force, and in the screams again and again, even the people with magic weapons fell down heavily, and even worse, not only did their faces be scratched, but even two or three teeth were knocked out.

Of course, for these ignorant and fearless fools, the passing audience mostly showed disdainful sneers. There are even more arrogant people, who laugh for it, and make sarcastic remarks, making the faces of those who fall green with anger.

These smiling people are all people whose strength is much higher, even if the embarrassed and embarrassed people are angry when they hear the sound, they can only keep it in their hearts and pretend not to see it.

In this world, whoever has the biggest fist and who speaks loudly has no strength, so he can only swallow his anger and suffocate himself. Seeing this scene, Chu He reviewed the precepts of his predecessors again.

When he got closer, Chu He realized that these walls were all made of some dark yellow rocks.

This kind of dark yellow rock, the Chu River is recognized, it is called pyrite, this kind of rock is mostly associated with many refined iron veins, and it is only found in hundreds of zhang deep underground. This rock is also the main material of the outer wall of Qingling Town.

This rock contains a lot of pure iron gas, each of which can only be formed by the strong pressure of the stratum for thousands of years, so its texture is extremely dense and hard, straight as steel. Even a cultivator at the seventh or eighth level of the Qi Refining Realm may not be able to smash a large piece of Yellow Iron Rock with a single punch.

It is extremely difficult to cast a city wall with this kind of pyrite, because the pyrite is much heavier than ordinary rocks, and it takes a lot of manpower and material resources.

There are orderly rune patterns engraved on it, and the rune light flashes from time to time, which is not conspicuous and slightly dim, but thousands of rune lights rise and fall, echoing and linking, and it is a magic circle.

Chu He has a little understanding of runes, and he knows some characteristics of yellow iron rock, and it can also be inferred that the city walls are mostly imprinted with earth and gold runes. Huang Tieyan is an excellent material to withstand the gold and soil rune array, such a huge city wall, if it is also a rune array of good grade imprinted on it, the power of the magic light formed by it is enough to block the monks who are not high in cultivation outside, according to Chu He's estimate, the average monk of the Yuan Dan realm, even if he has a magic weapon in hand, he really can't get this city wall in a short time.

Similar to this kind of city wall, the Chu River is no stranger, in the periphery of the Demon Cloud Mountain Range, there are many towns that are built like this.

It is so impregnable to resist the surging tide of beasts, and only such a wall can keep those terrifying demon beasts out.

I didn't expect that such a city wall could be seen tens of thousands of miles away. Chu He couldn't help but be frightened: Could it be that the beast tide can also affect here.

There is a record in the classics of Qingling Mountain: Because of unknown reasons, the demon beasts in the Demon Cloud Mountain Range will become bloody and irritable after a period of time, and then pour out of their nests to find blood food, forming a terrifying number of beast tides, radiating to the mountains in all directions. ...,

Since the establishment of Qingling Town, it has experienced the impact of a small beast tide, and it has survived under the concerted efforts of the sect and many powerful forces.

However, the scourge of that little beast tide also stopped at more than a thousand miles around the Demon Cloud Mountain Range.

If it is impossible to avoid the journey of tens of thousands of miles, could it be that it is a tide of great beasts? Chu He thought of a possibility, and a little cold sweat broke out for it.

If it is, it will not be a river of blood, but a purgatory on earth.

The city gate was imminent, Chu He shook his head, and put these chaotic thoughts aside.

At the city gate, there were two or three Innate Realm monks, wearing water-white robes, who should be disciples of the White River Sect.

The Baihe Sect dominates Baihe Prefecture, and a big city like Qingyuan City is naturally firmly controlled in its hands, and it will not be divided and ruled by other families like Baihu City.

In Qingyuan City, other forces may be able to drink soup or something, but don't want to touch the flesh and bones.

Maybe Chu He was good-looking, and he didn't attract any inquiries and investigations, so he easily entered the city.

After walking a few steps, a street more than ten zhang wide is in sight, and there are many pedestrians on the street, and there is even a crowded phenomenon in some places.

With such prosperity, Qingling Town may be comparable, but it has lost a lot in terms of scale.

At this moment, there were several monks who were cultivating at the fifth or sixth level of the Qi Refining Realm, wearing various colored clothes, and they were surrounding several monks who had entered the city towards Chu He.

Chu He didn't understand what they were going to do at first, and there was a trace of vigilance in his heart, but these people's cultivation was so low, and they were close to the city gate, so they couldn't make any waves, and they didn't take any precautions.

When they spoke, they understood: they had come to sell a detailed map of Qingyuan City.

This map can show everything in Qingyuan City in detail, and there are some places to eat, drink and have fun.

After Chu He paid for a medium-grade spirit stone, he got a jade slip.

As soon as the spiritual sense infiltrated into it, everything in Qingyuan City was indeed in front of him, quite detailed. But it's a pity that the inner city of Qingyuan City is a blank existence in this jade slip map, without the slightest information.

Chu He followed the map and went to an inn in the east. The place was farther away from the city gates, so it was naturally quieter. I didn't know that when I arrived at the inn, I was told that it was full, so please move. The same is true for a few more families.

Unexpectedly, the popularity of Qingyuan City was so explosive, Chu He was puzzled, until he asked an innkeeper, he knew that it was the season of green rice harvest, and there was an endless stream of merchants and merchants from various states who came here to buy, which caused such a situation.

"The eighth-rank Spirit Valley does have such a charm. Chu He touched his nose and walked towards the big inn mentioned in the jade slip.

It seems that this money cannot be saved.
