Lu Yuemei's method can prevent the two of them from accidentally falling into the formation, which is relatively safe.

Ye Xing took the mountain god and began to carefully search for the remaining formations.

This cemetery is not the deepest part of the entire mountain, the more you go inside, the wider the field of vision, a big reason is because there is no grass around, the war in the past has caused this place to become a barren land, the influence of antiquity is still there, these monstrous murderous aura makes it difficult to imagine how magnificent and terrible the battle here in ancient times will be.

In addition to these murderous aura, Ye Xing couldn't feel any formation fluctuations at all, which was no wonder, after all, the ancient period was at least five thousand years away from now, and if it was farther away, it could even be traced back to eight thousand years ago, even if it was an ancient battlefield, it was impossible to tell when it was an ancient battlefield, except for the hidden formation that had not been activated, it was difficult for an ordinary formation to last so long and still be intact.

Formations can be roughly divided into three categories, which are not the types of formations, but the durability of formations. First of all, the first is a formation that is completely laid out by cultivators, this kind of formation is somewhat similar to the talisman, although the power is huge, there are many types, but this formation relies on the complete energy supply, if the energy of the formation itself is used up, there is no follow-up supply method, the entire formation will lose its effect, so most of this type of formation are killing formations, although the power is huge, but it cannot last too long. Of course, many formations of this type are no problem if they are well prepared, and they can be maintained for ten days and a half months.

As for the second formation, it needs to borrow external energy, such as the phantom array. Most phantom arrays or trapped formations need to borrow the aura of heaven and earth, as long as the aura of this place is not exhausted, the formation will be maintained forever, so that people can be trapped in it forever.

There is also a natural formation, which will last forever unless the rules of heaven and earth change, or someone destroys it. However, unless the natural formation is extremely special, it will not be hidden.

For example, the hidden formation in this battlefield, if the activation conditions are not reached, it will not be revealed, as long as the formation is not activated, there will be no consumption, and many formations are not activated when someone enters the range of the formation.

The conditions for each formation to be activated are different, for example, some killing formations can only be activated if a master steps in, otherwise a random monk who refines qi will activate the killing array, and if it is discovered by those masters, it will definitely not enter rashly, and this killing array will be equivalent to losing its effect.

In addition to the requirements for cultivation, there are also formations that use blood as an activation condition, and only when you see blood will you be activated. Some formations need to be based on breath, some are based on position, a certain item, etc., and some are like Lu Yuemei who went to pick up the storage ring before, but there was no ring at all, just a trapped formation that induced you to touch.

In short, some powerful formations require a specific activation method, so some ancient formations can naturally be preserved for a long time.

However, these hidden formations are not impossible to discover, if you want to discover this hidden formation, you must at least reach the level of the formation master, if it is a talisman master, the requirements are even higher, and Ye Xing is only an intermediate talisman master now, and it is still far behind.

Therefore, the deeper he went, the more Ye Xing had to raise the spirit of the twelve, and carefully go deeper with the mountain god.

At this time, Ye Xing and Lu Yuemei didn't know that after the two of them came here, it was fortunate that they had only touched a magic circle after they had gone so far.

On the other side, Long Yi and Long Er had already chased to the Nine Shadows Ruins, and the two were suspended in mid-air, looking at the inside of the mountain.

"Big brother, these two people must have entered this mountain, but there seems to be a strong murderous aura in this mountain, could it be that these two people are ghosts again?"

Long Yi could also feel the breath of Ye Xing and Lu Yuemei, but in the same way, he also felt the murderous aura in the belly of this mountain, Long Yi thought for a while before speaking: "It is true that there is a murderous aura in the belly of this mountain, but it is not like it was created by these two people. This murderous aura was not only powerful, but also enveloped too wide, if the two of them could have such a murderous aura, they didn't need to flee all the way like this. ”

"Are you saying that the murderous aura here is formed by other reasons?" Long Er thought about it and felt that what Long Yi said made a lot of sense.

Such a large area of the mountain's belly is all shrouded in murderous aura, if these two people can control this murderous aura, as long as the murderous aura is gathered together, let alone them, even if the master of the Tribulation Period comes, he will be shocked by this murderous aura and unable to move.

The dragon nodded and said, "Here, it is very likely to be a dangerous place, the two of them brought us here, they should want to use this place to fight us." ”

"Joke, if this place can't even trap the two of them, how can it trap us. Ryuuji pursed his lips, his face full of indifference.

Long Yi was full of seriousness: "Since they dare to come to this place, it is likely that they are so sure, let's be careful." ”

Long Er gritted his teeth and said: "No matter what, I must kill these two people with my own hands to avenge the third, fourth, and fifth!"

The two looked at each other, nodded to each other, and flew towards the side of the mountain.

However, as soon as they landed, bursts of formation fluctuations came immediately, enveloping the two of them at once.

On the other side, Ye Xing also suffered the same thing.

However, it was not Ye Xing who triggered the formation, but the mountain god.

As soon as Ye Xing felt the fluctuation of the formation, he immediately felt the wind in his back, and subconsciously flashed to the side, and the mountain god's fist fell.

Rumble!

The punch that didn't hit Ye Xing smashed directly into the ground, and the surface of the ground cracked all at once.

Ye Xing frowned slightly, it stands to reason that once they enter the formation, the connection between Lu Yuemei and the mountain god will be severed, and according to Lu Yuemei, the mountain god will be controlled by Ye Xing at that time, but at the moment, Ye Xing can't control the mountain god, and the mountain god will attack him instead.

Obviously, the mountain god touched the formation, and in this formation, the mountain god was directly controlled.

In fact, there are many similar formations, and many formations are specifically aimed at monks like Lu Yuemei who can use mountain gods or summoned spirit beasts as auxiliaries, making the spirit beasts they summoned disobedient and attacking their masters.
