This set of laser alarms does not use 980nm invisible light cross-beam, but uses a relatively short wavelength of visible light dual-beam cross-beam, which is not difficult to shield. Lei Dong carefully observed the situation in the passage, and after making sure that there were no other alarm devices, he quickly crawled over, stopped next to the alarm, and used two sets of folding mirrors to smoothly shield this group of alarms, and the dark clouds quickly passed through the broken channel.

Fifty meters further, the two of them came to the exit of the ventilation tunnel, broke the dust cover in the same way as before, and carefully folded the steel wire mesh upwards to expose the passage opening.

According to the minimum tactical requirements, Lei Dong waited quietly in place for two minutes, and after making sure that there was no sound below, he took out the hose speculum from his tactical vest and stretched out the exit to look down.

The image on the display screen surprised Lei Dong!

This is a huge cave, more than a kilometer in diameter and an area of hundreds of thousands of square meters. The cave is not particularly regular, it can be seen that it is a naturally formed cave, but like the outer base, it has obviously been artificially modified, and the dome is cast in alloy and reinforced with three I-beams criss-crossed, which is an essential earthquake-proof facility for the earthquake-prone base located in the volcanic zone.

The smooth straight up and down alloy walls are clean and dusty, and heavy alloy three-proof doors are built on the wall, one by one. The floor is also paved with fine marble.

There was no light in the entire cave, only a faint diffuse light coming in from nowhere, which shrouded the ground, as if shrouded in a thin layer of hazy light.

If such a huge freezer is not enough to really surprise Lei Dong, then the scene seen on the ground of Lei Dong directly plunges Lei Dong into a huge shock.

On a mirror-smooth marble floor, this cave with a diameter of more than a kilometer is home to several traditional pavilions and lofts of Jeppen, as well as a wooden house with white walls and blue tiles, surrounded by a babbling stream. The stream does not have a source, but only emerges from the ground close to the wooden houses and a few hundred meters, passes through the pavilions, and finally draws a circle, from the outcropping to the ground and back below the ground.

What's even more weird is that around the wooden house, on the bank of the stream, there are a bunch of forest skeletons scattered in the east and west! These skeletons can't tell if they are male or female, but Lei Dong can tell at a glance that these skeletons are obviously not a normal death! Because the color of the skeleton had obviously not been weathered for a long time, and it did not have a little phosphorescence as it should be, it should have formed not long ago, but there was not a trace of decaying flesh on it. A normal skeleton is definitely not like this.

Moreover, if you look closely, there are still some parts of these skeletons that have black holes, as if they have been pierced by some sharp object.

"What's the situation? Someone is practicing the Nine Yin White Bone Claw here? Lei Dong was suspicious, where did these skeletons come from, and why did they change from living people to white bones? Below, what are the hidden secrets?

The wooden house in the middle of the cave was urgently closed, and he could not see the situation inside, and Lei Dong carefully released his divine sense and probed into the cabin. But there were still hundreds of meters away from the wooden house, and it was as if the Divine Consciousness had touched a thin barrier that isolated the Divine Consciousness. It seems to be a soft but tough eggshell that protects the wooden house and the surrounding area for hundreds of meters.

"Five Directions Spirit Gathering Array?"

Lei Dong almost cried out in surprise.

This feeling was all too familiar to him, it was on the Saint Emperor Light Island that the Water Yao Immortal had used to protect him and his entire team from being harmed by James Sam's lightsaber.

With this clue, and then looking at the pavilions and pavilions inside, Lei Dong really found that these buildings seemed to be disorganized, but in fact, they were arranged according to the direction of the five elements, arching and guarding the wooden house in the center - and the wooden house happened to stand in the position of the eye of the formation.

Could it be that there are cultivators here?

The old god stick master inadvertently mentioned that in this world, there are actually no republics, and other countries also have a number of cultivation inheritances, especially in the Jiepeng Empire, which directly stole the inheritance of the ancient cultivation school of the republic and formed a unique cultivation sect.

It's just that with the advent of the end of the Dharma era hundreds of years ago, the Xiuzhen sect in the world has basically disappeared, and it is difficult to find their traces.

First, under the mountain outside the base, the dark night guard was discovered, and then here, the five-party spirit gathering array was discovered, which only seemed to show that there must be cultivators here. If they were in charge, today's operation would have faced unpredictable difficulties.

But, no matter what the difficulties, today's task must be completed! Grandma's cultivator is a cultivator, and Lao Tzu is also a primordial infant monk! Lei Dong gritted his teeth and made up his mind without the slightest hesitation.

However, the situation was unclear, Lei Dong didn't dare to be careless, his divine sense and the film were touched, and he turned around and made a gesture to the dark clouds, signaling that he wanted to go down.

This vent location is different from the base hall, it is not set in the center of the cave, but slightly to one side, about 100 meters away from the alloy wall, about 200 meters away from the eye of the five-way spirit gathering array, it is already within the protection range of the formation, you must find a suitable foothold on the periphery of the formation, and land on the ground without making any sound at all without touching the formation.

As long as he was able to do this, with his familiarity with the Five Directions Spirit Gathering Array, Lei Dong had the confidence to approach the cabin in the center of the formation without a sound and assassinate the guards inside.

Looking closely, the diameter of the exit is about 1.5 meters, volleyed on all sides, and there is no borrowing force at all, Lei Dong thought about it, stuffed the hose speculum back into the tactical vest, took out the static rope and connected it with the "O" ring on the lifeline between the crotch, and handed the other end to the dark clouds.

Wuyun sat on the ground, wrapped the static rope around his right leg in an "S" bend, then stepped on the rope on the surface of his left foot, kicked his legs on the edge of the exit, and tensed hard, supporting the whole body weight to form a descending bracket, and the upper body leaned back slightly, holding the static rope tightly in his hand to control the descent speed and ensure that the rope would not make any sound due to contact and friction with the rock wall.

Seeing that the dark clouds had tried their strength and were fully able to support it, Lei Dong nodded and slid out of the hole silently.

In mid-air, Lei Dong bent his body and turned into a head and feet, holding an MP9 submachine gun in one hand and the handle of a P224 pistol equipped with a silencer in the other, holding his breath, his eyes firmly against the ground to prevent being hit by the enemy, and his body slid silently to the ground.
