Ye Qing walked ahead with a submachine gun on his back and a fire axe in his hand, exploring the way. Jiang Yan walked behind with a backpack on her back as usual.

The road at the beginning could only accommodate two adults, and it was rugged and difficult to walk.

The further they walked in, the more black stalagmites of different heights and scattered boulders appeared in their field of vision.

They looked natural, but if you look closely, there are still traces of later artificial carving.

Some places with steep slopes have been made into steps.

As for some protruding stalagmites beside the main road, they have been patinated by people passing by.

Not only are they smooth, but they also glow.

With Ye Qing alone by her side, Jiang Yan was much less worried.

After walking for a while, she reached into her backpack and actually took out a high-intensity flashlight from the space.

Ye Qing also held the hand-cranked rechargeable flashlight in his hand, but the light was very dim, which was better than nothing.

The two of them walked slowly and quietly along the main road, one in front and one behind, and they didn't walk far before they found a very obvious fork in the road.

One went up, and the other went down.

Jiang Yan swept the flashlight up and down, and her eyes stopped at the bottom.

Not far away, in the narrow gap between two natural mountain walls, there was a plank road made of branches.

Those branches were as thick as wrists, and the side branches were cut off and crooked.

They originally came here to find wood.

If all the branches on the plank road were taken back, they would be enough for them to burn for a while.

There were actually many dead trees and wooden boards floating in the water outside, but they were wet and obviously could not burn.

"Go down."

"Yes."

The two of them stopped and looked at each other, and made up their minds at the same time.

When they got closer, Jiang Yan discovered that under the dense plank road, there was actually a very deep gully formed by nature.

Judging from the light and shadow reflected by the flashlight, there should be water in it.

The gully was very deep and gradually narrowed.

If a person fell down, the probability of survival would be almost zero.

Jiang Yan didn't know what the point of building such a plank road was here. After all, at the end of the plank road, there was a natural crack in the stone as wide as a palm.

The crack in the stone spanned the dome, and it was unknown where it led to.

This reminded her of the tomb-robbing novels she had read before.

But it was only a flash, and she withdrew her thoughts.

"Jiang Yan, you stay here, I'll go up." Ye Qing handed the submachine gun on his back to Jiang Yan.

He also had a fire axe in his hand. The branches were directly stuck on the stone walls on both sides, so it was not difficult to take them down.

But to take those branches, you have to walk to the end of the plank road, and then back up one by one to remove them.

Jiang Yan glanced at the bottomless ravine and said, "Why don't I go? I'm light, and you can hold me up from above."

"It's okay, I'll test the load-bearing capacity of the branches first." Ye Qing knew what she was worried about. After saying that, he had rolled up his sleeves and raised one foot to slowly step on it.

The branches under his feet made a "creaking" sound, sank a little, and then stabilized.

This branch has a good load-bearing capacity.

Ye Qing stood very skillfully, with his legs spread as far apart as possible to disperse the pressure.

Jiang Yan had no choice but to take out a rope from her backpack and let him tie it to her body in case of an emergency.

The other end of the rope was tied to a nearby stalagmite.

In less than a minute, Ye Qing had walked to the end of the plank road in a nimble manner, and slowly squatted down and started to tap "bang bang bang".

The broken stones knocked off by the axe on the edge were scattered everywhere, and some crackling sounds of falling water could be heard faintly.

Ye Qing's movements were very agile. In less than a few minutes, he had removed all the branches.

The whole process was safe.

Ye Qing retreated to the ground and took out a thin ordinary rope from his backpack. The two worked together to tie up the branches.

"Jiang Yan, you said that this area is considered to be a relatively high position here. Is there no one who escaped here?" Ye Qing pressed the branches with his legs and tightened the rope while whispering.

The two were very cautious before and hardly spoke along the way.

"I don't know, it stands to reason that there should be someone."

Jiang Yan was also confused.

There is obviously a way to get up here.

The belly of the mountain is relatively warm in winter and cool in summer, which is much better than being outside.

It can just avoid high temperatures and heavy rains.

Looking at the tight appearance of the mountain, it should not have experienced an earthquake or anything.

But the few people did not find any traces of human habitation in the cave outside and along the way, which was indeed a bit strange.

In addition, if there were people living there, these wooden planks that could be used to make fire would not be their turn.

Jiang Yan had a bold guess in her heart:

"Is it possible that the natural disasters experienced in each place are similar? This area has experienced something before, so there are no people left."

According to Song Qian, this mountain is hidden in an ancient village.

It seems that the population density is obviously not as high as in the city.

It is not impossible that everything was lost in a natural disaster or man-made disaster.

"It's not impossible." Ye Qing nodded, and his thoughts coincided with hers.

High temperatures and bloody mosquitoes are indeed experienced by the whole world.

The reason why we know this is because the communication can still be used normally at that time, and everyone can see the latest information.

As for what happened afterwards, everyone only knows the situation nearby.

So is the whole world experiencing the same disaster at the same time?

It is unknown.

Or, the whole world will experience the same disaster, but some secondary disasters are obviously different.

Just as Song Qian said, the situation in Dongshan is not just as simple as high temperature, there is also very serious radiation.

This makes sense.

Dongshan is located on a plateau with high terrain, and the ultraviolet rays before the end of the world are obviously much higher than other plains.

And this time, Anming, which is located in the earthquake zone, was severely damaged and obviously much better than Xiangyun where it is now.

"If the natural disasters experienced by each place are different, then after experiencing many natural disasters, the survivors will be gradually concentrated in some areas that are most suitable for survival, just like the great migrations in human history around the world.

And according to history, those who first occupy advantageous locations are likely to become the founders and rulers of the new order." Ye Qing had tied the last knot while speaking.

Jiang Yan listened to his words, thinking of the five private bases mentioned by Song Qian, and was thoughtful.

Ye Qing on the opposite side raised his head, looked at her seriously, and lowered his voice a bit and said:

"Jiang Yan, that Song Qian, although he doesn't look like a bad guy, he is a subordinate of Mo Jingsheng in Yaoben Base.

That base is somewhat related to Lieyan Base.

You'd better be careful in the next few days when you go to Dongshan."
