A large-scale inspection of the entire underground cave began. Yin Dong ignored those trivial matters and instead explored the cracks deep in the underground cave. There was a huge boulder blocking the entrance to the crack so tightly that ordinary people could not push it open.

Yin Dong accidentally noticed the spiritual energy seeping out from behind the boulder, and after touching it, he realized that the boulder was moving.

After removing the boulder, a dark and unfathomable fissure was revealed, which was nearly a hundred meters deep. It had not yet reached the end. Yin Dong's heart beat inexplicably fast, as if he sensed an invisible crisis.

And after going a hundred meters deep, the sense of crisis gradually intensified until the hairs all over the body stood on end and the surrounding air seemed to be frozen, making it feel like being in an ice cave.

Yin Dong held his breath and moved forward, going deep into the crack very slowly, getting slower and slower with the sense of crisis, for fear of making some movement that would alarm some unknown existence deep in the crack.

He plans to use the underground cave as a temporary base, where most of the fleet will be stationed before leaving Donglai Mountain and returning to Baishan Base.

If there is a dangerous existence deep in the fissure, if he can remove it, he must remove it quickly. Otherwise, the people in the underground cave must be removed as soon as possible.

The light in the depths of the fissure strangely did not become dark as the depths of Yin Dong deepened. Instead, it gradually became brighter, as if a torch was burning. The light of the fire swayed, making people sway in response to the reflection on the rock wall.

Occasionally, there is a crackling sound.

Looking at the transmitted firelight, Yin Dong did not feel a trace of warmth. Instead, he felt a chill on his back, as if cold air was seeping into the pores of his body.

Yin Dong's nerves tightened, and he quietly and quickly penetrated deep into the fissure, and with the help of the terrain, even if he could hide his figure, he dived deeper into the fissure.

The rock wall of the fissure is not dug, but a natural opening. The cave wall is not smooth and has many intertwined sharp stone protrusions, so it is not difficult for Yin Dong to hide his figure when moving forward. Moreover, the fissure is sloping downward.

It is also relatively easy for him to climb down the rock wall.

After sneaking for nearly 10,000 meters, Yin Dong saw an artificially dug vent. It was very secret and blocked by gravel. It was not big, only about the size of a watermelon, and there were gusts of cold wind blowing from it.

Yin Dong approached the vent and heard a strange sound suddenly coming from inside the cave, like the sharp claws of some ferocious beast scratching on the stone.

He cleared away the rubble from the vent and dug with his bare hands. When he expanded the vent to allow an adult to get in, he heard strange noises inside, and there was a shadow cast by the fire. As the fire swayed,

The shadow was also twisting and shaking.

Arriving here, Yin Dong's heart has been filled with a strong sense of crisis. For the sake of safety, it is wisest for him to retreat now. But he is a little unwilling to find a place suitable for tens of thousands of people to be stationed. It is difficult to find this place.

The underground cave group is very suitable for current needs.

What's more, under natural disasters, there is no guarantee that there will be danger?

No matter what, he had to figure out the source of this sense of crisis. After enlarging the hole, he went straight in without hesitation. After getting to the other side of the vent, the sound of claw tips scratching on the stone became clearer.

Shaking and twisting in the firelight

The shadow also shook more violently.

Yin Dong continued to move forward, but at this time, he was no longer in an underground fissure, but a corridor paved with blue bricks. The firelight was emitted from the oil lamps on the walls on both sides of the corridor. The lamp oil was refined from some kind of animal fat, and emitted

A burnt aroma of barbecue mixed with the rotten smell permeating the corridor.

The further he walked, the lower the temperature in the corridor. When he didn't activate the Dragon Essence Bodyguard, the blood in his body seemed to be freezing.

Yin Dong walked along the corridor for a long time. He didn't see anyone, nor any animals, nor heard any other movement in the corridor. However, the sense of crisis in his heart became stronger, making his hair stand on end.

A chill ran up my spine and quickly spread throughout my body.

Did he seem to have overlooked something?

This thought flashed through Yin Dong's mind. Before Yin Dong could think about it, wind suddenly blew up from the back of his head, and a sharp burst of air came with Senhan's murderous intent, making his scalp feel like it was going to explode at this moment.

boom!

Completely subconsciously, Yin Dong backhanded a Blood Dragon Claw. In a hurry, he was caught in the incoming black shadow. There was a loud bang, and the wall of the corridor was blasted away by the explosion wave, with gravel flying and many sharp objects flying.

Stones flew out, some hit Yin Dong and were shaken into stone powder, and some shot into the black shadow, making a series of banging noises.

All this is complicated, but it all happened in a few breaths. Yin Dong was not aware of where the black shadow was hiding in advance. He was even attacked, and he didn't know what it was.

When Yin Dong struck out, his body turned over, only to find that the black shadow that attacked him had exploded, and mixed with the flying gravel, they were all gray and black fragments, and it was impossible to tell what they were.

In the corridor, after a sound of debris falling to the ground, silence returned. If you didn't look at the gravel on the ground and the damage on the wall, you would have felt like you were hallucinating just now.

Yin Dong's expression changed. That dangerous existence was staring at him. Moreover, the guy seemed to be somewhat elusive and hard to guard against. Even if he wanted to retreat now, he might not be able to escape intact.

After looking around, Yin Dong did not stop where he was and continued to move forward. He was still unwilling to give up now. And the cold wind coming in from somewhere in front made the corridor become colder and colder. Even the corridor

A thin layer of ice was frozen on the green bricks on the floor.

Click, click, click...

Suddenly, Yin Dong heard the sound of something crushing thin ice from a crack in the corridor. The sound was a bit far away, and sounded a bit erratic in the cold wind that poured into the corridor, but it made the blood in his body rush.

It started to boil as if being pulled, and the heart beat like it was being hit by a heavy hammer.

Yin Dong's expression changed with shock, and he felt a strong desire to retreat. He didn't want to take any more risks, but his body seemed to be controlled by a mysterious force and kept moving forward.

The thin ice on the green bricks is getting thicker and thicker, the temperature is falling rapidly, and the rate of decline is very fast. The cold air has formed a mist in the corridor. Yin Dong felt that his face was about to become numb from the cold, when a sudden change occurred!

With a bang, the wall exploded in the section of corridor he had just walked through, and an animal claw with exploding scales stretched out, grabbing Yin Dong like lightning.

Yin Dong's reaction was quick. He rushed forward and rolled again, and saw the beast's claw slamming down hard, just grazing his left shoulder and hitting the ground. If he had been slower, he would have definitely been killed.

Will be hit by the claws of the beast.
