There are hundreds of huge chains that make up the iron bridge, and these chains stretch side by side from the edge of the cliff to the depths of the clouds, and of course, the iron ropes are so stable that those who walk on them do not feel anything. What is frightening is not that anyone will accidentally fall into the abyss below, this fear comes from the bottom of everyone's heart, that is, the fear of the unknown, after all, no one knows whether the other end of this iron bridge is an exit or a yellow spring.

The yin wind kept gushing up from below, making people's backs feel a little chilly, but it was a pity that the little girls in the Heavenly Dao Academy did not appear here, otherwise, what kind of scenery should it be if the cold wind lifted the skirt.

"Hey...... What the hell are you thinking? fuck ...... The saliva is pouring out. ”

Chu Ge rarely burst into a foul mouth, Zhang Heng's previous expression was too obscene, and there was no one else here, this phenomenon really made him break out in a cold sweat, and he unconsciously clenched his hips.

Zhang Heng realized that he was out of shape, so he coughed dryly twice, and he didn't expect Chu Ge to be wary of himself at this time, and said that he wouldn't let him continue to walk behind.

"Qin Shan, they obviously walked in, but in the end they returned to the same place, if they didn't lie, there should be some kind of formation prohibition here. If we don't destroy this place, we're afraid we'll be repeating the mistakes of the past. ”

Zhang Heng rubbed his chin, looked at the still white patch in front of him, and said with a somewhat solemn expression. Hearing this, Chu Ge remembered that when he first climbed the mountain, he had attacked the sun, and only then did he break free from that illusion. Obviously, that sun is the formation eye that Zhang Heng said, but if there is really a formation here, then what is its formation eye?

Chu Ge looked around, and then locked his gaze on the iron rope under his feet. Zhang Heng was shocked and said angrily: "I, don't mess around, I don't want to die." ”

Chu Ge glanced at him with disdain and said, "Why are you so nervous, although I don't know the way of the formation, but since the white hair has gone out from here." If there really was such a thing as a circle, this iron rope would not be intact, I was just thinking about how he did it. ”

"Is there anything else you don't understand?"

"Hmm...... That's a lot. ”

The two of them stopped and fell silent at the same time, there were only the two of them on the iron bridge, if it was according to the normal situation, Qin Shan and the others had already followed their footsteps. But behind them there was only a thick fog, and there was not a sound from them.

On the iron bridge, their vision was only a few feet away. No one knows if they're heading towards the exit or heading back. It's a strange feeling, and they're sure they're not skewed in the skew of their steps when they step on the bridge, but where does that feeling of stepping on the return journey come from?

They noticed this subtle change, as if someone had reversed the entrance, but fortunately, they had a feeling, at least the possibility of following this trace to find a breakthrough.

"I've always wondered, who arranged these strange formations?"

"Maybe the whole mountain is a formation. ”

Chu Ge closed his eyes. Feel the fluctuations of the aura of heaven and earth.

The things between heaven and earth that can be absorbed by cultivators and belong to themselves are divided into two types, starlight and aura. The former provides direct power to the cultivator, while the latter can play a supporting role. Xinghui can be condensed into Xingyuan, and the aura can change the attributes of the Xingyuan, and the aura is divided into five elements, for example, Chu Ge's ice attribute Xingyuan can be classified as water, so he can easily perceive the fluctuations of the water attribute aura between heaven and earth.

Although the Ice Star Yuan is made of eternal cold air. But this cold air comes from this heaven and earth in the final analysis, and so does the imperial fire of the white warbler. The attribute star element seems to be powerful, but it also has its own drawbacks, such as once it absorbs the aura of heaven and earth, it is equivalent to putting a puddle of sludge into the clear water. The star element will become impure. The direct consequence is that with the continuous improvement of the realm, those sludges will sooner or later block the mouth of the pot, making the progress of the realm slow or even stagnant.

This is also the fact that most cultivators have not absorbed the aura to change the attributes of their star elements, and the same is true for Zhang Heng, he does not have the imperial fire and the eternal cold qi in his body, let alone take the initiative to absorb the aura of heaven and earth, so when he really wants to master the flow laws of these breaths, it will become extremely difficult.

He didn't have a deep understanding of formations, but he also knew that many formation masters could rely on those aura control formations to create illusions and even change the world. About three hundred years ago, a formation master set up a large array in a city in the north, so that the people in the city lived in the illusion for a hundred years, but when these people woke up, they found that it was only a day.

The rumors may be exaggerated, but it is true that those masters rely on manipulating the aura of heaven and earth to preside over the formation.

"You can feel it?"

Zhang Heng looked at Chu Ge with a suspicious face, and after a while, he realized that his question seemed to be a little redundant. This kid's Ice Xingyuan is so domineering, and the flow of water attribute aura must not be able to hide from him.

Chu Ge closed his eyes, but his skin was much sharper than his eyes at this time, the ethereal aura in the heaven and earth seemed to have been gathered by someone, and the flow of aura should have been irregular, but over this iron bridge, they flowed in one direction in an orderly manner, but the strange feeling that arose in his and Zhang Heng's hearts just now was precisely because the aura suddenly changed the direction of flow. Both of them could feel it, but the difference was that Chu Ge's feeling was much stronger than Zhang Heng's.

Since the aura is the key to controlling the formation, it has reversed the direction of flow, and if the two of them continue to walk forward, they will only return to the original point like Qin Shan and them.

"Presumably, those people will soon discover the key to this formation, as long as the direction of the aura flow changes, we can turn around and walk out of this fog. ”

Chu Ge opened his eyes and a smile appeared on his face.

Zhang Heng nodded and agreed, as long as this was confirmed, even if Chu Ge did not lead the way, he could go out by himself. There are only two directions on the bridge, and whenever that strange feeling arises, just turn around and keep walking. The problems that plagued the two of them were easily solved, these topics seemed difficult, but once they figured out the doorway, it couldn't be easier, at least it was easier than asking Zhang Heng to make a good poem, I don't know how many times easier.

Both of them thought so, but they both ignored one point, that is, the biggest problem left by the holy mountain for them was not a test of knowledge and experience, let alone cultivation strength, but people's hearts.

There is no ban on killing on the mountain, even if old classmates fight here, no one will say that yours is not, there are many people participating in this conference, and the strength is uneven. The fundamental reason for this situation is not that there is no threshold for students, but that those who are not strong want to find a suitable place to solve things that cannot be solved on a daily basis, such as revenge.

Finding a way out, the two of them couldn't help but relax a lot, and even the terrifying information contained in the few corpses at the entrance was temporarily forgotten. Zhang Heng is a person who talks a lot, and naturally he can't stop for a moment in this atmosphere, from his own scenery in the Alien Demon Domain, to how to get to know Lu Su and other things, Chu Ge also listened to them one by one, he is not as heartless as Zhang Heng, he knows Qingfeng's strength very well, not to mention that there were three Juxing and two Star Mansions present at that time. Except for gray hair, who has the ability to erase those people so easily?

And, if there is no deep hatred, why do you do this? I can't figure it out, I really can't figure it out. It wasn't until Zhang Heng inadvertently mentioned the alliance between the two clans that Chu Ge was stunned and inexplicably thought of a possibility.

If it weren't for Bai Hao's hand, Xiao Zhang, who ranked second, was a student of Tiandao Academy, so it couldn't be his hand, and as for the third to ninth being taken over by the Seven Sons of Xiling, these people also had no need to make a move. Since it weren't for these people, it was impossible for all the contestants in this Qingyun Conference to have the strength to easily kill those few people.

Unless the person who killed them was not the young talent who participated in the convention.

This conjecture is really a bit creepy, but Chu Ge has already thought of this, but he himself feels absurd and has not said it, who would be bored enough to sneak into the holy mountain to kill people, what good is this for him? If Chu Ge's mind has long been shrouded in doubts, the thing that Zhang Heng unintentionally mentioned is the dawn that breaks through these doubts.

It's just a pity that behind the clouds is not a clear sky, but an even more eerie sky.

Although these were all conjectures, Chu Ge's back was still wet, and his face looked extremely unnatural. Zhang Heng noticed his strange appearance, and his brows couldn't help frowning, this guy was even blocked out of the door by the sixteen academies, and his face was light, what made him like this?

"Did you think there would be any demons sneaking in?"

Chu Ge swallowed his saliva and spoke. His face was not pretty, but it was not a sign of fear, and his eyes were reddened as if they were suppressing hatred, so much so that he sounded a little gnashed when he said this. Even Zhang Heng originally wanted to say something ridiculous, but after seeing his appearance, he didn't say it, just pouted and said: "Impossible, unless those old men are all eating rice, do you know how important these people who are staying on the mountain now are to human beings? ”

"After all, for so many years, Shushan is the only place on the continent that has not been touched by alien demons, and there is naturally a reason for this. ”

Zhang Heng didn't agree with Chu Ge's point of view, thinking that he was worrying about the sky, but the latter's next words made his confidence shaken a little. (To be continued......) R1292
