Zhang Yuan has been hiding in this place and waiting, and during this time, the only thing Zhang Yuan did was to keep using the source realm center in his hand to check the entire Zhangcheng and everything around it, but with Zhang Yuan's continuous observation, he found that when this Zhangcheng was built, everything was built around the Spirit Weapon Sect, as if the sect master of the Spirit Weapon Sect had a very strong desire to control, so when building the Spirit Weapon Sect, everything must be centered on the Spirit Weapon Sect, which made it so that when Zhang Yuan stood at the door of the Spirit Weapon Sect, he found that he could overlook the entire Chapter City。

Suddenly, Zhang Yuan thought of something, because the entire Zhangcheng can be rotted in the place of the Spirit Weapon Sect, so the shape of the Zhangcheng naturally became a long strip, after all, only in this way can it be guaranteed to be seen by Zhang Yuan, and this kind of city seems to be very similar to a very common magic weapon, and then, Zhang Yuan began to guess whether Zhangcheng was very particular when he named it.

After all, Zhang Yuan was not a native cultivator of the Source Realm, so there were many things that Zhang Yuan didn't know, so Zhang Yuan immediately contacted Zhang Yue, who was still in the Huazong Cave Mansion, and asked him to immediately investigate the history of Zhangcheng.

For such a thing, the disciples of the Eagle Hall are really very powerful, after all, this is not a too confidential thing, and some sects that pay attention to inheritance will have records in this regard, so soon, among some legends about Zhangcheng, those that are more reliable will directly converge into Zhang Yuan's hands.

The construction of Zhangcheng was more than a thousand years ago, and the Spirit Weapon Sect was still a relatively powerful sect at that time, after all, the cultivation fault had just happened, so many practitioners had not really grown up, so at this time, the Spirit Treasure in the hands of the Spirit Weapon Sect had become an important barrier for a practitioner or a sect to develop and grow immediately, so there were many practitioners or sects who had the idea of the Spirit Weapon Sect.

Although the Spirit Weapon Sect is indeed extraordinary when refining the Spirit Treasure, it is really not good in terms of fighting, so in that era, since the Spirit Weapon Sect left the Source City and settled here, it seems to have really become a pedal for the development of other sects and cultivators, any cultivator sect or individual who wants to obtain the Spirit Treasure dares to come directly to the door, and the request is also to tailor a special Spirit Treasure for it, which makes the Heaven and Earth Treasure stored by the Spirit Weapon Sect's own sect be squandered, because more often, those cultivators who come to the door will not carry any Heavenly Materials and Earth Treasures, and if the Spirit Weapon Sect refuses, it was inevitable that there would be another fight, and in desperation, the Spirit Weapon Sect could only shatter its teeth and swallow blood.

Of course, in the face of such a situation, Wan Jianyi, the first sect master of the Spirit Weapon Sect, also hoped to find a way to get rid of it, but if he couldn't make his sect stronger, then such a thing would continue, so Wan Jianyi thought of a way, as for what this method was, because the time was too long, and there were many people who didn't understand it at that time, so it was gradually buried in the long river of history, but it can be concluded that this method has a certain relationship with the establishment of Zhangcheng, because after Wan Jianyi thought of a way, he immediately began to build Zhangcheng, and during this time, the Spirit Weapon Sect rejected all the sects and cultivators' requests to customize the spirit treasure, even if it was to pay the entire sect for this.

In this way, during the construction of Zhangcheng, the entire Spirit Weapon Sect stopped refining the spirit treasure, and during this time, the only thing everyone cared about was the establishment of Zhangcheng, and all the disciples of the Spirit Weapon Sect had to worry about the area they were responsible for every day, whether it had been built in accordance with the requirements of the sect master Wan Jianyi, and in this way, it took more than two years to be busy before Zhang Cheng was established under the care of the Spirit Weapon Sect.

Of course, because I haven't continued to refine the spirit treasure for more than two years, the day when the establishment of Zhang Cheng was completed, many sects and cultivators came to the door again, and the requirement was to continue refining the spirit treasure, after all, the things that the Spirit Weapon Sect needs to be busy with have also been completed, so now we should continue to help everyone refine the spirit treasure.

And the most unexpected thing is that those cultivators or cultivators who came to ask for refining the spirit treasure only stayed in Zhangcheng for three days, and then left inexplicably, as for the reason, no one really knows, and there is a rumor that these people who entered Zhangcheng passed away one after another after a few years, as for whether this rumor is correct or not, no one knows, because when those cultivators left Zhangcheng, one by one was fine, the only difference is that they no longer quarrel and ask the Spirit Weapon Sect to help everyone refine the spirit treasure, so they will live in Zhangcheng for three days, left Zhangcheng directly, and as for what happened a few years later, no one continued to track it.

At that time, this incident caused a shock in the entire source world, and many powerful sects sent cultivators to Zhangcheng to check, but without exception, there was no gain, and to ask those cultivators who left Zhangcheng, but the answer they got was the same, inexplicably, they didn't want to continue refining the spirit treasure, so they left Zhangcheng directly, because this incident did not cause any damage to the cultivators at that time, although it was still an unsolved mystery, but gradually, it was forgotten by everyone.

Seeing such a situation, Zhang Yuan knew that his guess must have come true, this Zhang Cheng definitely has its own problems, but where is the specific problem, Zhang Yuan really can't find it for a while, but since Mai chose here, he must have discovered the real secret here, so Mai will use this opportunity to complete the fact that he collects the souls of cultivators.

After suddenly discovering this secret, Zhang Yuan's first reaction was to return to Zhangcheng and find out the final secret of Zhangcheng, and the other was that he hoped to notify those cultivators to leave here as soon as possible, since they thought that they had found the formation they had arranged, and they had destroyed this formation, they could leave completely easily, so that they could avoid being collected more souls by Mai.

It's just that the idea comes and goes quickly, after all, all this is just his own speculation, and if he lets those people leave at this time, I don't know if Mai will start to launch the special settings of Zhangcheng in advance, so that those cultivators will leave this world in advance, so it is just a momentary impulse, Zhang Yuan immediately vetoed it himself, compared to these cultivators in Zhangcheng, Mai's appearance is more important to Zhang Yuan, so Zhang Yuan decided to continue to wait and see what happens, and during this time, he can also carefully study the real secrets of Zhangcheng。

Because after suddenly discovering the secret of Zhangcheng at this moment, when Zhang Yuan observed again, he no longer searched every inch of Zhangcheng one by one, and now Zhang Yuan is more willing to observe the entire Zhangcheng as a whole, after all, only in this way did Zhang Yuan really find that this Zhangcheng was very similar to a seal, and before the Spirit Weapon Sect where Zhang Yuan was standing, it seemed that he could just hold this seal in his hand, and then seal it forward.

As if to confirm Zhang Yuan's thoughts, Zhang Yuan pulled his eyes away again, and at this time he realized that in the direction opposite the gate of Zhangcheng, at the end of the field of vision, there were continuous mountain ranges, and Zhang Yuan vaguely remembered that he had not been able to observe this mountain range before the Spirit Weapon Sect, and the observation seemed to be clearer, so Zhang Yuan suddenly felt that he had found the real secret.

Without any stopping, Zhang Yuan teleported directly towards the mountain range in the distance, but Zhang Yuan didn't realize that when he was looking for the real secret of this chapter city, the time had unconsciously come to the evening of the third day.

Although the mountain range can be seen, there is still a long distance from Zhangcheng, so when Zhang Yuan teleported to the mountain range, it was already half an hour later, of course, Zhang Yuan also knew that because everything came from his own speculation, Zhang Yuan himself was not sure what the final result was, in addition, the time required for himself to do it was not a fixed number, but Zhang Yuan never expected that the result he wanted to find appeared in front of him so quickly。

Just when he just came to this mountain range, what appeared in front of him was a cliff, and the smoothest side of the cliff was facing Zhangcheng, and on this cliff, Zhang Yuan found what he was looking for, the mark of a seal, which was engraved with the four words of the spirit weapon seal in an ancient font, but because of the age, these four words have been somewhat blurred, but the only thing that is not blurred is a border that appears around these four words, and the border directly frames the four words together, making them a whole。

Because he knew that these four words should be inextricably linked with Zhang Cheng, so Zhang Yuan began to study it carefully, if you look at it at first, these four words don't seem to be too special, but when Zhang Yuan carefully studied it, he found that the original writing of these four words was not done in one go, but was formed by the convergence of countless small dots, and as for these small dots, if Zhang Yuan's guess was not wrong, I am afraid that it was hit by one old magic weapon after another, and the surrounding border was actually encircled not only by these four words, but by these magic weapons that played four words。

At this time, Zhang Yuan finally understood that the reason why the Spirit Weapon Sect wanted to establish Zhangcheng was not that it did not continue to refine the spirit treasure, but that it was only refined one by one before, and this time, the Spirit Weapon Sect directly refined the entire Zhangcheng into the Spirit Weapon Sect's Guardian Spirit Treasure, of course, the purpose was to protect the Spirit Weapon Sect from being oppressed by other sects and cultivators.

Of course, if you want to refine such a huge spiritual treasure, there is still no way for the cultivators of the Spirit Weapon Sect to do it, so the sect master of the Spirit Weapon Sect thought of a way, that is, to directly combine countless spirit treasures to make it a more powerful spirit treasure, and at this moment, the mark on the cliff is actually the only function is to aggregate these spirit treasures.

After discovering all this, Zhang Yuan also had a certain guess about Mai's specific behavior, although Zhang Yuan didn't know what kind of use this giant spiritual treasure was, but once it was really used, it would definitely have a certain impact on the cultivators living in Zhangcheng, and it was very likely that if this huge seal of Zhangcheng wanted to be used, it would also need some other special conditions, so Mai would choose to do it at a certain time, and at the same time, Zhang Yuan also thought that when he checked in front of the Spirit Weapon Sect before, all the roofs of the entire Zhangcheng City had become a dilapidated color, in fact, the real reason, It should be that he wants to hide the spiritual treasures that Mai prevented from being in it, and at the same time be able to divert his attention, after all, the Spirit Weapon Sect was the only place where the secrets of Zhangcheng could be discovered before, and Mai definitely wouldn't want to find out all this.

Thinking of the time, Zhang Yuan suddenly realized that he seemed to have forgotten a little, because it was about to come to the time that Mai said, and it was absolutely impossible for him to rush back directly at the moment, so I am afraid that it would be a little impossible to stop Mai from making a move.

Again used the center of the source realm to look in front of the sect of the Spirit Weapon Sect, and sure enough, at this moment there was a person wearing a cloak standing there, and the black cloak completely shrouded this person in darkness, so that Zhang Yuan could not see the other party's appearance at all, but it seemed that when Zhang Yuan checked it, it seemed that the other party noticed it, so this person suddenly looked up to the sky, and it was also at this time that Zhang Yuan finally found that Mai who he couldn't find appeared here, and at this moment, Mai's eyes suddenly flashed a smile。

Seeing the smile in Mai's eyes, Zhang Yuan really had some hateful teeth, but after all, the distance between the two was too far, so Zhang Yuan couldn't do anything at all, just when Zhang Yuan was about to set off to rush back, he suddenly found that Mai's lips moved, and he simply said four words, and then waved his arm fiercely in the direction of Zhang Cheng, and Zhang Yuan felt that a dangerous force was flying towards the place where he was standing at a rapid speed.

Mai's last four words, Zhang Yuan saw clearly, just like the words left by Mai in the mountain city before, Mai told Zhang Yuan, "You're late again!"

After seeing the four words that Mai left for himself, Zhang Yuan's heart was still a little annoyed, annoyed that he couldn't find the final answer faster, if he could have discovered all the secrets earlier, then he shouldn't have been in front of this cliff at this moment, but in front of the sect of the Spirit Weapon Sect, he successfully detained Mai, but now it seems that it is too late to regret it, because Mai has already launched the special seal of Zhang Cheng, and Zhang Yuan is likely to be the first to see the attack ability of this huge spiritual treasure of Zhang Cheng。

Looking at the cliff again, Zhang Yuan felt that the weathering degree of the four words of the Spirit Weapon Zongyin and the weathering degree of the surrounding frame were too different, which seemed completely illogical, so, the ghost made the god worse, when Zhang Cheng's attack was about to come, Zhang Yuan stepped forward again, took out the treasure money, and drew it against the mountain wall, of course, Zhang Yuan's stroke was not arbitrary, but to the surrounding border strokes, and successfully took a section of the border off the cliff, but after all, Zhang Yuan only had time to shoot once at the moment, so the frame that was cut was only a small piece, and then Zhang Cheng's attack came, which is fiercely imprinted on this cliff.

I thought that Zhang Cheng's attack would be very powerful, but when it really came, it was just a gentle drizzle, Zhang Cheng's attack was only imprinted on the cliff, and it did not break the cliff, the only result was that the four words of the very powerful spirit weapon sect that had been weathered were suddenly re-depicted, and they clearly appeared on the cliff again.

Frowning and looking at the result in front of him, it seemed that his random blow did not change any results, so Zhang Yuan did not continue to stay, and began to teleport in the direction where Zhang Cheng was, and at this time, when Zhang Yuan wanted to reposition Mai, he found that the entire Zhang Cheng disappeared from his supervision again, apparently after the successful attack, Mai once again used his master feng shui technique, so that Zhang Cheng was suddenly separated from this world, so Zhang Yuan completely lost the trace of Mai。

When Zhang Yuan returned to Zhangcheng, he found that the entire Zhangcheng was already a dead silence, and the cultivators who had gathered in Zhangcheng before were lying on the ground silently at this moment, Zhang Yuan checked these people who fell to the ground, and found that these people did not have any injuries, but they all lost the fluctuation of their souls, Zhang Yuan didn't know, it turned out that when Zhangcheng really attacked, it was not the distant mountains that were really hurt, but these cultivators who were in Zhangcheng.

At this time, Zhang Yuan finally understood that the real function of Zhangcheng was actually only to absorb the soul power of those cultivators who lived in Zhangcheng, but this time Mai was more ruthless than Wan Jianyi, the first sect master of the Spirit Weapon Sect, and directly wiped out all the cultivators, and the original Wan Jianyi also left a trace of life for those people, so compared with the two, Mai in front of him was even more ruthless.

Just when Zhang Yuan stood in the empty Zhangcheng and sighed, suddenly a person gradually stood up from above the ground, and with the beginning of this person, then people continued to stand up from the ground, which made Zhang Yuan a little surprised, but after a little thought, he understood that it should have a certain relationship with his previous attack, and in the end, the one who successfully survived this attack was only one-tenth of the entire Zhangcheng cultivators, and the others fell forever in the cold streets of Zhangcheng。
