This person's voice was sonorous, like a golden stone striking each other, it was the Phantom Bamboo of the Lei Yin Sect, and he asked everyone's questions.

Trap Mountain is a small place in the Demon Abyss, but it is also thousands of miles in radius, and although there are many demon suppression troops on the giant flying boat, it is impossible to surround them very tightly.

Three days have passed since the three demon marshals fled into the Trap Mountain, and perhaps the Shadow Demon has already run away.

The captain of the Demon Suppression Military Academy who introduced the situation was called Zheng Fei, of course he understood this truth, and explained:

"The Ice Jianbing True Monarch has already laid down the Ice and Fire Double Extreme Array and sealed the Trapping Mountain, so the Shadow Demon must still be in the Trapping Mountain."

It turned out that there was a large array surrounding, and everyone understood, but this ice and fire double extreme array obviously only had the effect of blocking, and could not be found, or even killed the demon commander in the array.

Zheng Fei presided over the distribution of the formation cards for entering and exiting the big array, and arranged the general strategy for everyone to search after entering the Trap Mountain.

Because the Shadow Demon can transform into a Demon Hunter, everyone has set a password and code to recognize each other.

In the end, Haihong Zhenjun said: "The big array outside the Empty Mountain was temporarily laid by Jianbing Zhenjun, because the terrain and spiritual veins are not suitable, so it can only hold on for another seven days."

"We can't stay here for the sake of the three marshals, so after seven days, no matter what the outcome is, the operation will be over.

"Everyone should hurry up, blow the whistle immediately when you find the demon handsome, don't be greedy."

"Yes!" Everyone agreed in unison, all of them are veterans here, although they all have their own plans, coveting the true skill of punishing demons, but they also know the priorities, in the face of the demons, they should move the people, and they should not make mistakes because of their own selfishness.

Chen Jing took out a white bone whistle and looked at it, this is the "Demon Whistle" mentioned by Haihong Zhenjun, it is a kind of sound transmission magic weapon, the sound emitted can be transmitted far away, and if you are in distress in the Demon Abyss, you can blow the Demon Whistle for help.

Because the fog in the Demon Abyss will absorb the sound, although the whistle of the Demon Whistle is far away, it is only a few dozen miles, and the distance of dozens of miles in the vast Demon Abyss is too small, and there is little hope of being heard, and it is possible to attract the demons.

So the Demon Whistle is a thing that seems to be very good, but it is actually very chicken, Chen Jing and Liu Fei'er have long had a Demon Whistle, but they have never used it, nor have they heard of it in the Demon Abyss, including the time when they assisted Wu Zhao.

However, in this situation, in the Hollow Mountain surrounded by a large array, the searching people will not go too far, and the Demon Alarm Whistle is too easy to use.

Everything was arranged, and Haihong Zhenjun led everyone into the Trap Mountain.

A large transparent shield appeared in the fog ahead, and the shield disappeared into the fog on all sides, and it was difficult to see the whole picture, but it was conceivable that the shield must be huge.

There were two colors of light blue and light red on the shield flickering from time to time, and it looked a little unstable, Chen Jing thought to himself, this Ice and Fire Double Extreme Array really couldn't last for a long time.

Jianbing Zhenjun should have a powerful set of array flags, so he can lay down this large array in a short period of time, but because the mountain and river spiritual veins are not suitable, he can only barely maintain it for a few days.

The array cards had been sacrificed before, and everyone passed through the large array and entered the Trap Mountain.

Through the fog, you can see the undulating hills below, and there are many bottomless vertical holes and crevasses between the mountains.

These vertical holes and fissures extend all the way into the interior of the mountain, and they are also interconnected and complex.

If these vertical holes and cracks continue to expand, it is likely that the Hollow Mountain will become a terrain like the Wanfeng Stone Forest.

This time, more than forty elite demon hunters came, divided into more than a dozen teams, and now each team was responsible for a vertical hole or crack, and they all drilled into the mountain, and Haihong Zhenjun answered from above.

Listening to what Zheng Fei said just now, the Jianbing True Monarch of the Demon Suppression Army was searching elsewhere in the Trapping Mountain.

The Demon Hunter in the Yudan Period can search a range of a few miles in the middle of the Fallen Demon Abyss, and the Yuanying True Monarch can search for dozens of miles, which is indeed much stronger, but compared to the vast Fallen Demon Abyss, the efficiency is still not high.

In the complex caverns inside the Hollow Mountain, the difference in search ability between the Demon Hunter and the Yuanying Zhenjun in the Yuedan period has been further narrowed, so it is best for Haihong Zhenjun to wander above to support.

Chen Jing, Liu Fei'er and Chongshan entered a crack, this crack was bottomless, when they looked at it, because the crack was full of thick fog, it looked like a gray-white pool, but when they entered the crack, it became darker and darker, and became chaotic and dark.

In the cave cracks inside the mountain, the Phantom Bee can see not far and is easy to get lost, the fog gourd will affect other demon hunters and cannot be used, and the effect of the sky-piercing miniature of the mountain is also greatly reduced.

And those three demon commanders are strong, so the three of them have long decided to put safety first and act carefully.

The Phantom Bee, the Fog Gourd, and the Celestial Miniature were not easy to use, but Chen Jing still decided to come, so he was naturally prepared, and after encountering the cave in the Spruce Rift, he also thought of a way to search in the cave.

The three of them walked forward in the crack with all their attention, and five or six phantoms flew into the cracks of the surrounding caves.

There is a faint connection between Chen Jing and the illusions created by the mirage gourd, and some simple information can be perceived with the help of illusions, and now using these illusions to search with great fanfare can reduce their own danger, and have the effect of startling the grass and snakes.

The caves and cracks in the mountain were very complicated, and after searching for a while, Chen Jing realized that even with the help of phantoms, it would be difficult to search them one by one.

After thinking about it for a while, Chen Jing said to Chongshan: "Let's pay more attention to the key access passages and see if we can find the traces left by the demons." ”

Chongshan responded: "Okay! ”

In the dim and oppressive cave, Liu Fei'er felt that her sword intent was not affected too much, but the caves in the mountain were intricate, and the sword intent could not help much.

The caves here are relatively smooth up and down, while the lateral caves are relatively few, and there are often dead ends.

Passing through a cave, the three of them had already entered another area, Chen Jing had seen the Bafang Concentric Disk, there should be no other demon hunters here.

This is the eight-sided concentric disk specially prepared by the Demon Suppression Army for this operation, there are more than forty people in total, each of whom has a piece, and the actions of nearby squads can be observed through the concentric disk.

The three of them cautiously continued to search, because the cave was narrow, and the activity space and observation range were severely limited, Chen Jing felt more and more that it was not a good idea to search for the demon marshal in the Hollow Mountain.

The Demon Suppression Hall should also know, but there is a shadow demon among the demon commanders, and even if this shadow demon only wanders in the fallen demon abyss, it can cause great harm, so he is looking for it.

After searching for more than a day, Chen Jing, Liu Fei'er, and Chongshan found no trace of the demon clan.

Chen Jing had also been observing the Bafang Concentric Disk, and found that the progress of several groups of demon hunters nearby was also relatively slow, after all, in the cave, the environment was more favorable to the demons who were good at melee combat, and everyone was very careful, and the speed was naturally not fast.

Suddenly, a shrill voice pierced through the fog and came from above.
