Hearing Elder Jing say that the Source Crystal of the Ice Immortal City Spirit Gathering Array should be replaced, Master Mu even claimed that the Xuan Yuan Crystal had been carefully put away by him, and the magic staff he used to tease his old opponent Master Huo had already been taken back by him, and at this time, his hands were empty, leading everyone to the place where the Spirit Gathering Array was.

Master Huo didn't want to watch his opponent enjoy the results of the battle, so he greeted Elder Jing and his party from the general association, ignored others, and directly took out the flying carpet, the flying carpet became larger and spread on the ground, Yan Xiancheng and his party went up, Master Huo's mind moved, and the flying carpet carried everyone, and fled away at a speed like a lightning speed.

In a few breaths, he had disappeared into the sky, and at this time, Master Huo didn't want to stay here for a moment, otherwise it would only add fuel to his fire and make him even more angry.

Of course, before leaving, Huo Bao stared at Sisi coquettishly, Sisi was thinking about his thoughts, and he didn't see his gaze, so there was no such thing as eye contact.

Jun Jackdaw looked at Chu Tian, and his eyes no longer had the kind of perverted psychology that abused him, but were filled with deep fear.

Just as he was afraid of his younger brother who he thought had taken everything from him, no matter how dissatisfied he was, he could only forcibly suppress himself, first because of the family, and then because of the younger brother himself.

Several other people also stared at their opponents who had fought each other, and those who could be on their par with them were always easy to attract attention, and a few pairs of eyes collided with a series of sparks in the air.

Cheng Xuan didn't look at Chu Tian at all, he just thought about things sullenly, gritted his teeth, and clenched his fists.

He didn't resent Chu Tian, he just hated himself, if he wasn't careless, how could he make such a big mistake when he used the Golden Shield Technique at a critical time?

Elder Jing followed Master Mu and them to replace Xuanyuan Crystal, and they always had to be a witness, which also meant that they would always attach importance to the Ice Immortal City Branch.

The location of the Spirit Gathering Array is a secret place, and only the high-ranking members of the association are allowed to enter it.

Those who are qualified go with them, and the ordinary audience who are not qualified are still unsatisfied with the two competitions just now, and while discussing with high expressions, they slowly disperse.

Everyone's hearts were filled with joy, and after the replacement of the Xuanyuan Crystal, any spiritual cultivator in this city would be able to obtain practical benefits, which was exciting news.

In view of the excellent performance of Chu Tian and others, the association authorized Chu Tian and other five players to witness this moment, and a senior executive gave them a message before leaving, and the players followed according to their words.

Leaving the playground, past the small buildings nearby, and leaving the communication area, the group twisted and wound in the ice crystal passage, and finally after passing a certain hall, the walking passage gradually lowered and spiraled to the underground.

There are lights on both sides of the passage, and the ice crystal ground is very bright, and the eye can see in the passage, even if there is no sunlight, it will not feel dark.

Chu Tian estimated that he went down more than 100 meters, and a gate was horizontal in front of everyone's eyes, several tall and long, and it seemed to be very magnificent, and one after another powerful fluctuations spread out, Chu Tian was secretly frightened, and he was keenly aware of the indestructibility of this gate with his perception.

According to his perception, even if the Transformation Gang Realm tried its best to shake this door, I am afraid that it would be like a mayfly shaking a tree, and it would not be able to shake it at all, and as for the powerhouses of the higher level, he would have no way to judge.

In fact, when it comes to the Huagang Realm, even if the martial artists of the Ning Dan Realm cast a peerless skill at the bottom of the box, or the strong people of the Nian Sect do not hesitate to spend a lot of spiritual power to cast forbidden spells, it is no different from a child tickling an adult for this door.

This gate is used to seal the Spirit Gathering Array, not only is it strong, but even the surrounding surface has been changed because of it, and it is also indestructible, so it is hard to enter.

This is also reasonable, this Spirit Gathering Array can be said to be the lifeblood of the entire Ice Immortal City, if it is not strong enough, once the war breaks out and affects the Ice Immortal City, if the Spirit Gathering Array is destroyed, even if it is repaired, it will cost a huge price, not to mention the creation.

At least in the entire Ice Immortal City, there is no one who has the level of creation, and if you want to go, you will always ask for help, and invite powerful characters to come over.

Moreover, this kind of super-large city-specific formation is generally not completed by a formation master, and if you invite a group, the price is too high, even if it is a master's meeting, you will never be willing to pay it unless you have to.

The seal on the door has extremely high authority, and it can only be lifted by Master Mu himself.

Master Mu suddenly popped out his palm, and complex lines appeared in his palm, as far as Chu Tian could see, it was many times more difficult than the decoding of the blue crystal cultivation room he cultivated, and it was at least hundreds of times more difficult than the visual inspection.

Such a difficult pattern is almost impossible for human beings to memorize and describe, in fact, even if it is still drawn, it is useless to draw exactly the same, and it is necessary to use the original version in the master's hand, so the security level of this door can be described as extremely high.

The position of the close hand on the door also shows the lines, which are complementary to the lines on Master Mu's hands.

Just like heaven and earth, sun and moon, yin and yang, male and female, water and fire, it is like a natural pair and an underground pair, and the two fit together, as if they are a world of their own.

When the group entered, Master Mu immediately closed the door, so as not to let the young people take advantage of the inattention.

As soon as he entered the door, Chu Tian clearly sensed that the location of the Spirit Gathering Array was not too far away, and the corner in front of him revealed a light, and he couldn't stop flickering, this was not because he sensed how keen, but the fluctuations of the Spirit Gathering Array were too obvious, if there was no ban on the gate, even if he was far away from the Ice Immortal City, he could clearly detect it, it was too eye-catching.

As he walked around the passage, the light became more and more intense, flashing and flashing, and his eyes were tingling, and it was to protect his eyes with spiritual thoughts, so that he no longer moved the stinging.

After a few turns, an underground hall appeared in front of them, and Chu Tian was deeply shocked by the scene in front of him.

This hall is extremely large, just like a medium-sized square, on the square, as if sensing the existence of the source crystal that Master Mu received, the Taoist lines emerge, profound and mysterious, and extremely simple, just like the truth between this heaven and earth.

The lines spread vertically and horizontally like cobwebs, occupying the entire hall, Chu Tian couldn't help but gasp, how could he ever see a formation of this scale.

Han Junxiao and a few others also showed a look of amazement, Sisi was no exception, the county town naturally also had a giant formation at the same level, but it was a secret place, and her father didn't dare to treat her to that kind of place, this was a dereliction of duty, and it was known by the imperial court, even if it was a county guard, it would be heavily responsible.

The Dao pattern flickered, vaguely revealing a touch of humanized excitement, Chu Tian sensed this, and couldn't help but be taken aback again, the formation has wisdom, is this still a formation?

After thinking about it, he felt relieved, since the spirit weapon can use spiritual intelligence, and the formation has spiritual wisdom, and he doesn't know what to make a fuss about.

Master Mu closed his eyes slightly, and the young people didn't know what he was doing, and only a few high-level people knew that he was communicating with the Spirit Gathering Array.

The flickering light of the Spirit Gathering Array seemed to produce some kind of anomaly, and it also revealed a taste of dialogue.

Soon, Master Mu opened his eyes, took out the Xuanyuan Crystal, and walked towards the Spirit Gathering Array, the Spirit Gathering Array dispersed the light, and a white crystal appeared in the center, the quality of this Spirit Source Crystal was inferior to the Xuanyuan Crystal by one level, and the light was dim, which was a sign that the energy was about to run out.

There will always be a particular time chosen, if the source crystal is not replaced, this old piece will not last for a day or two, and at most the energy inside it will be exhausted the day after tomorrow.

Master Mu approached, took down the old Lingyuan Crystal with a special technique, and installed the Xuanyuan Crystal that he had just won.

The Spirit Gathering Array was slightly silent, and then a more brilliant brilliance burst out, the Dao Dao lines were thicker than before, and waves of powerful fluctuations emanated, and anyone could feel that the quality of the Spirit Gathering Array had gone up a whole level.

This array is not closed, but extends in all directions, with channels connecting all important places of the association.

Through these channels, the Spirit Gathering Array transmits the energy of the Xuan Array Source to these places through the channels.

At the same time, the entire association and even the entire Ice Immortal City underwent earth-shaking changes.
