"This array of locking spirits can block the leakage of spiritual energy, and it can also resist the invasion of external forces. However, just this one formation is impossible to keep this place until now. Within this formation, there must be other formations. Gu Feng's voice sounded.

"No matter how many formations there are, it's up to you. Nie Chen smiled.

She definitely wouldn't do such a drudgery as cracking the formation. Handed over to Gu Feng, it is naturally the best choice.

"Leave it to me?" Gu Feng chuckled, "Do you think that now I can still go out and help you crack the formation?"

"Eh, this ......" Nie Chen was stunned, and really ignored Gu Feng's state.

Gu Feng incarnated into the spirit of the Cave Heaven, and all the power of cultivation disappeared, and all that was left was the realm of true gods. In addition, he is a spirit body at this time, even if he condenses the clone and walks out, it is difficult to have the strength to break the formation.

"Otherwise, let the madman come out to help me?" Nie Chen pondered.

"You can, so why bother others. That's good, I'll pass you the method of cracking, and you can do it yourself. Gu Feng's voice sounded again.

"Well, well. Nie Chen nodded helplessly.

Although the formation is strong, it is really not difficult for a true god. With Gu Feng's guidance, Nie Chen quickly gained something and opened the first protective formation.

Just like Gu Feng guessed before, this formation was just the beginning. Within the formation, another formation emerged, still resisting Nie Chen's footsteps.

This second formation is not much different from the previous one. Nie Chen had the previous experience, and his speed was a little faster. It was only a tea time before and after, and Nie Chen had a harvest again.

However, at this time, Nie Chen was not happy at all. Because she found that within the second formation, there were still formations. And the two ways that Nie Chen cracked only made her advance by more than ten meters.

If there are many formations in it, it will be an extremely time-consuming matter. Nie Chen wasn't sure how much time he had left, but he didn't want to waste it all on cracking the formation.

"Let the madmen help you. Gu Feng's voice sounded.

Gu Feng's original intention was to let Nie Chen crack the formation alone, sharpen her state of mind, and by the way, also master some formation techniques.

But now, the number of formations seems to be extremely large, and the patterns are almost repetitive. If you continue to let Nie Chen crack it alone, it will be a waste of time.

Nie Chen naturally had no opinion, and with a turn of his mind, he summoned the madman out and asked him to help him crack it together. The cultivation of the mad Daoist is slightly lower, but his understanding and attainment of the formation method are far superior to Nie Chen's. With his help, Nie Chen's speed of cracking the formation instantly became more than ten times faster.

Dean Xu followed behind him, looking at the two people not far away, his eyes were a little straight. Although he knew that Nie Chen had special abilities, this great change was still beyond his imagination.

Fortunately, Dean Xu was well-informed and recovered quickly after a brief shock. followed the two of them step by step, constantly moving towards Devil's Mountain.

He has studied this devil's mountain for several years, but there has never been much breakthrough. Now that Nie Chen has appeared, he has seen hope, and naturally he will not give up this opportunity.

"Dean Xu, you'd better stay a little farther away so as not to hurt you by mistake. Nie Chen turned around and reminded.

Dean Xu is just a mortal, and he is a little older. If he was really affected by the power of the formation, he was afraid that he would not be able to bear it at all.

"It's okay, you go ahead, I'll be careful. Dean Xu responded, but there was no intention of stopping at all.

Nie Chen knew that he would not retreat, so he did not continue to waste words and persuasion. However, secretly, a cultivation power spread out, enveloping the dean. This strength is not too strong, but it can protect his safety and not be injured by the formation.

In the following days, Nie Chen was busy cracking the formation. And the number of formations has reached an astonishing number of thousands.

"When will this road come to an end!" Nie Chen couldn't help but complain.

With so many formations, the mad Dao people felt a little irritable, not to mention Nie Chen, who was impatient.

"In my opinion, it shouldn't be much. The madman spoke.

"Not much, but we've only advanced a few hundred feet, and we're still far from the core of the mountain. Nie Chen glanced into the distance, and his face showed a depressed look.

"Miss, do you feel that the formation behind this is a little different?"

"No? When you say that, I remember. The formation inside seems to be much weaker than the outside. ”

"Yes, it's weak. According to this trend, the formation inside will become weaker and weaker, and eventually disappear completely. ”

"That's strange! Logically speaking, the formation was set up to protect this place. Even if it's not getting stronger and stronger, it's about to be on par with the outside. What is the effect of becoming so weak?" Nie Chen was puzzled.

"I know that. Gu Feng's voice sounded.

"What?"

"This formation is called the Great Soul Formation. This formation itself is not strong, but it has a special feature, if it is constantly attacked by external forces, it will gradually strengthen the power of the formation.

The formation in this place has been arranged for many years, and it has been constantly eroded by the power of the outside spirit, so that the outer layer of the formation has gradually strengthened. And the internal formation, because it is far away from external forces, cannot activate the special feature of the formation, and it is naturally a little weaker than the outside. ”

"This formation is so strong, isn't it invincible in the world!" Nie Chen's eyes lit up.

She thought of Tu Tian, if she used this formation on him, wouldn't it make this formation more powerful.

"It's not possible. Gu Feng spoke, naturally knowing what Nie Chen was thinking, "This formation has a weakness, that is, the strength it can bear cannot exceed its maximum limit. Otherwise, not only will it not play the role of enhancing the formation, but it will also make the formation collapse instantly. ”

"Eh, chicken ribs!" Nie Chen held his forehead.

This kind of formation can only be used to protect some special places, and it is useless to really use it against the enemy. Trapping a low-level monk does not need such a formation, and the high-level monk can directly shatter it, making it even more difficult to have a chance to slowly strengthen.

"This kind of formation is not meant to be used against the enemy. It is generally laid out to protect some special places. ”

"You mean, there's something special in this Devil's Mountain?"

"Possibly. ”

"Then go in and have a look. Nie Chen became interested, and the previous fatigue disappeared in an instant.

As the formation weakened, the cracking speed of the two accelerated again. Finally, after a day, they entered the interior of Devil's Mountain.

From the outside, this is an ordinary mountain. But when you really go inside, it's a different scene. The mountain in front of me is huge, far more than any other in this world. Even Everest, known as the tallest one, is insignificant in front of him.

"What a high mountain!" Dean Xu followed behind him, and couldn't help but sigh when he saw this.

"Here, there's a familiar atmosphere!" Nie Chen's face showed surprise.
