Faced with this situation of suddenly falling into the forbidden formation, although Xia Mu was a little surprised, he quickly regained his composure and began to think about how to open the situation in front of him.

As for the formation prohibition, although Xia Mu is not proficient, he is also very familiar with some of the basic knowledge. Generally speaking, no matter how clever the formation prohibition is, you only need to find the foundation of the formation prohibition and destroy it, and the formation will naturally be broken.

So at first, Xia Mu naturally had the purpose of looking for the formation base, but it didn't take long for Xia Mu to feel bad.

Because after some careful observation and research, he found that this formation was not a simple formation, but a composite formation containing multiple prohibitions in it.

At present, the effectiveness of this formation has been reflected in two kinds, one is to confuse the perception of the person entering the formation, causing the person to be unable to get out of the scope of the formation, and the other is that the formation implies illusion, although this illusion has little effect on Xia Mu, who has experienced too illusory realm, but it is still very threatening to the other four.

And because of the existence of this illusion, if Xia Mu wanted to find the foundation of the formation forbidden by this formation, it would undoubtedly be much more difficult than the ordinary formation.

After half a day of searching, Xia Mu not only did not find the foundation of this formation, but also fell into the illusion in the formation many times because of this, although he quickly woke up, but after so many illusion illusions, Xia Mu also became a little dizzy and dizzy for a while.

As for casting a spiritual attack, Xia Mu had already tried it, but after the spiritual attack was cast, it was like a mud cow entering the sea, without causing a single movement.

In this way, his plan to break the formation with force was in vain.

After wandering around in this formation space and experimenting for a while, Xia Mu, who still found nothing, finally stopped, only to see him sitting cross-legged on the ground, his eyes slightly closed, and his mind began to recall what he had seen all the way from the beginning when he fell into the formation prohibition to the present, hoping to find some strange flaws from it, so as to break out of the formation.

Time passed minute by minute, Xia Mu's figure sat motionless, and around him, there was a constantly changing strange scene.

I don't know how long it took, Xia Mu's expression finally moved, and he slowly opened his eyes, looking at the illusion around him with a hint of enlightenment in his eyes.

"Tut, I see, the formation base is actually hidden in these illusions, if you want to find the formation base, you must let go of the inner room automatically fall into the illusion, so that you can find the formation base that changes its position with the change of illusion. Xia Mu smiled on his face and whispered to himself, and then he stepped forward, and he automatically stepped into those illusions.

In the next moment, I saw Xia Mu's body frozen in place motionless, but his divine soul had already entered the illusion and became one of them.

Time passed slowly, and I don't know how long it has been, Xia Mu's fingers, whose body has been stiff and immovable, finally moved, and then saw his eyelids move slightly, and he completely woke up from the illusion, with a trace of clarity in his eyes.

"It seems that I guessed correctly, the foundation of this formation is 'alive', and it can change its position with the change of these illusions, fortunately, my divine soul will is strong and firm enough, otherwise it would be impossible to see through this. Xia Mu muttered softly in his mouth, and then the essence light in his eyes flashed, and the spiritual power in his body swept out, pouring into his arm along the tendons and veins in his body.

"Go!" Xia Mu raised his eyebrows, and after a low snort in his mouth, he punched somewhere in the formation space.

In an instant, a dragon-shaped fist shadow flew out from Xia Mu's right fist and bombarded a certain void in the formation space with lightning speed.

With the loud sound of "boom", centered on the void that was attacked by Xia Mu, the entire formation space began to fluctuate violently, and then the surrounding illusion turned, Xia Mu only felt a flower in front of him, and the whole person suddenly reappeared on the familiar stone steps, and not far behind him, there was the skeleton lying impressively.

"Xia Jiuyou!"

"Xia Daoyou!"

......

It was at this moment that several exclamations sounded beside Xia Mu. Xia Mu turned his gaze, only to see the four Mu Qingxian who had just come out of the formation space, at this time, the four of them looked sluggish, their spirits were a little trance, and they seemed to have not completely gotten rid of the influence of the illusion in the formation.

"A few of them are also out of trouble!" Xia Mu glanced at Mu Qingxian without leaving a trace, and then looked at the other three and said.

"It was Xia Daoyou who broke the ban on this formation! I didn't expect that in addition to Qiu Daoyou, Xia Daoyou was actually proficient in the formation, but thanks to Xia Daoyou, otherwise I would have been killed by that illusion. Li Dequan's eyes quickly regained a trace of clarity, and his heart palpitated.

Obviously, this monk in the late stage of the Shentai suffered a lot of losses in that formation space, and his mind was still in a trance. Although the situation of the other three was not as bad as Li Dequan's, they also looked depressed, and they didn't know what they saw in the illusion of that formation space.

"It's just that my divine soul power is a little stronger than that of ordinary monks, so I can see through those illusions, otherwise even if I see the flaws in this formation, if I want to break the formation, I will not have enough strength to break it. Xia Mu snorted, and did not intend to dwell on this issue, but changed his words and said: "This trial path is specially prepared by the Starry Sky Immortal Lord for his disciples, if I guess correctly, Fang Cai's bones are the key to activating the formation prohibition, once someone touches it, the formation will be automatically activated." ”

"Xia Daoyou is right, it seems that anything I find on this trial path in the future cannot be easily touched. Mu Qingxian glanced at Jin Tianci and said.

"Let's be more careful in the future, this is the creation of an eternal saint, no matter what strange things happen, it's best not to act rashly, after all, the purpose of my wait is to arrive at the Starry Sky Immortal Hall on the top of the mountain." Qiu Shuixian nodded.

"Hehe, this time Jin is a little reckless, and he will not act rashly in the future. Jin Tianci generously admitted his mistake, this move couldn't help but make Xia Mugao look at him, if this person's personality is really as Mu Qingxian said, then he can still be a terrible opponent.

"Now that all of you fellow Daoists have understood, let's continue on the road, after all, the sooner we arrive at the Starry Sky Immortal Palace, we can also relax our hearts earlier. Xia Mu glanced in the direction of the top of the mountain, and then continued to walk up the stone steps first.

The four Mu Qingxian naturally followed closely behind.

This time, the five of them walked for several hours before they were stopped by a spiritual power barrier, and in front of this spiritual power barrier, there was a stone stele.

And after reading the method of passing through the spiritual power barrier recorded on the stone tablet, the five of them all fell into a deep thought.

This spiritual power barrier is the second level of the three levels leading to the top of the mountain, and it assesses the combat power of the trialist. According to the different strength of the trialists, the strength of this spiritual power barrier will be adjusted by itself, taking Xia Mu as an example, his current cultivation is the middle stage of the Shentai, so if he wants to pass through this spiritual power barrier, he must exert the combat power of the late stage of the Shentai, and attack the spiritual power barrier with the attack power comparable to the late stage of the Shentai, so that it can be broken.

This is a trial for geniuses, and those who are not far superior in combat power cannot pass it.

At this time, except for Xia Mu, the other four were all pondering, Li Dequan was a late-stage Shentai monk, so if he wanted to pass, he had to strike a blow comparable to the peak of Shentai, and Jin Tianci and Qiu Shuixian, as the highest Shentai peak cultivators among the five, had to exert an attack comparable to the early stage of the Five Elements Realm.

As for Mu Qingxian, Xia Mu couldn't figure out what kind of cultivation she was doing now, so it was not easy to speculate, but in any case, this level in front of him was an opportunity for him to observe the strength of the other four, and in the face of this level, unless the four of them were willing to give up the treasures in the Starry Sky Immortal Palace, otherwise, they would have to show some of their true strength, and even go all out to break through the level.

People with the same thoughts, there are also four other people, but they have completely given up the idea of wanting to see through the strength of Xia Mu, because before entering the Ten Thousand Bone Cave at the beginning, Xia Mu had already shown combat power comparable to the late stage of Shentai when he fought with Li Dequan, so this level in front of Xia Mu is not difficult to pass, which the four of them know well.

"Ladies and gentlemen, you can only rely on your own strength to break through this level in front of you, since you all don't want to be the first to break through, then Xia will take the first step. Half an hour later, Xia Mu made a decision in his heart, raised his footsteps, and took the lead towards the spiritual power barrier.

And his move also completely fell into the eyes of the other four, only to see Mu Qingxian and the four of them looking up one after another, although they all knew that with Xia Mu's strength, there was absolutely no doubt that they could pass, but even so, they wanted to confirm it with their own eyes.

What they want to confirm is not Xia Mu's strength, but whether everything said on the stone tablet is true, whether it is true that as long as the combat power exceeds the same level, they can pass through the spiritual power barrier in front of them.

"With the respect of the eternal saint, it should not be enough to use his hands and feet on the stone tablet. Standing in front of the spiritual power barrier, Xia Mu took a deep breath, the spiritual power in his body surged, and then he swung out a punch, and immediately a dragon-shaped fist shadow bombarded out, hitting the spiritual power barrier.

In an instant, the spiritual light burst out, accompanied by a low roar, in front of Xia Mu, the spiritual power barrier cracked from the middle, and a crack appeared that could be walked through.

Swish!

It was at this moment that the sound of breaking wind sounded behind Xia Mu, and he saw Li De's whole body unfolding, and he burst out with extreme speed in an instant, intending to rush through the crack before Xia Mu.
