I closed my eyes and tried to regain my strength.

But I was always thinking about the outcome of the battle of Changbai Mountain.

When I fell into the lava, I once saw my grandfather hurrying over, would he go to find Empress Tizi and Ji Wendi?

Dad and several uncles, did they escape from Changbai Mountain safely?

Also, the fifth uncle died......

The thought of this makes my heart ache a little.

Damn the national teacher of troubled times, if it wasn't for his sneak attack, how could the fifth uncle die in his hands?

If I ever make it out of this underworld alive, I'll have to find a way to kill him!

My mind was so cluttered that I couldn't rest very well.

I don't know how long it took in a daze, until there was a faint rumbling sound in the depths of the darkness, and I woke up suddenly.

I'm worried about the underground world having geological movements again.

I've known for a long time that the Underworld, though vast, is not everywhere to live in.

The first is that only the underside of the continental shelf is suitable for the survival of the revenant and underground creatures.

The second is where the geology is relatively stable.

For example, the twelve cities of Xudu, the eighteen layers of hell, and the places where the listening scriptures and the city of life and death are located, have rarely seen large-scale geological movements for thousands of years.

In places like Changbai Mountain, you will be shaken from time to time, and the rocks above your head will fall again, and even if there is a large enough underground space, it will be destroyed by geological movements sooner or later.

There is not even a ghost in this place, and it is obvious that it belongs to this kind of geological disaster-prone zone.

I know that the rumbling sound just now is that there are rocks collapsing in the distance, and the earth's veins are unstable.

It's just that the sound of the underground world is transmitted through solids and does not rely on air, so I can't tell how far away the geological movement is from me.

I thought about it for a moment, and without hesitation, I packed up my things and continued to follow the leyline.

The next days are relatively boring, so when you are tired, you will rest, regulate your breath, and continue to move forward after recovering.

In the darkness, I don't know the passage of time, let alone day and night.

Even the watch I always wear on my wrist was burned out by the magma, and I don't know how long it was.

This is also my psychological quality is strong enough, otherwise this oppressive environment, the rugged road, and the kind of oncoming darkness will never lead to the end of the underground road.

Even if it's an S-level exorcist, it's estimated that it's a little unbearable.

According to my calculations, it took about seven or eight days before I finally found an underground river.

After finding the underground river, I used the yin-yang compass to calculate the direction and began to follow the underground river upstream.

I don't know how deep I am in the underworld, but I do know that if I follow the underground river, I will probably follow the river back to the surface!

When I found the underground river, I also became energetic.

The chances of returning to the ground suddenly increased a lot.

And I found a fish without eyes in the underground river.

To be precise, the fish's eyes degenerate into small white spots, because it is in the dark all year round and does not need eyes.

But I found that the soul of this fish is very powerful.

Although it is not as powerful as a human soul, it is about three times stronger than the rest of the animals!

I know that this fish is likely to use soul fluctuations to probe the surroundings, as long as it is within the range of soul perception, it is basically equivalent to an eye.

And the soul fluctuation to explore the way, it is 360 degrees without dead ends, which is much easier to use than the eyes.

The only thing that makes me wonder is that such a powerful soul fluctuation is said to give fish a much greater chance of generating intelligence.

In other words, if I'm not mistaken, this fish must have become a climate spirit!

If there are spirits, civilization will be born.

Moreover, this is an underground water system, and it is said that as long as it is an underground water system, it will be under the jurisdiction of the Styx Mansion.

As for me, I happen to have another identity, that is, the young master of the River Styx.

Thinking of this, I immediately lifted my spirits and began to walk along the underground river.

Along the way, this strange fish without eyes also comes and goes.

Sometimes you can see two or three in a short period of time, and sometimes you can't see one after two consecutive breaks.

It wasn't until there was no road ahead that I stopped with a frown.

Strictly speaking, it's not that there is no way out.

Rather, the river turned from a bright river to a dark river.

In other words, I need to pass under the water to continue swimming against the current.

I hesitated for a long time, but I never made up my mind.

Because I don't know how long that dark river lasts and what I'm going to encounter in it.

There are also many underground rivers with many branches, and if I go the wrong way, I risk getting lost in the vast underground water system.

I'm not afraid of death, because even if I die, the three souls and seven spirits will be there, and I will become the young master of the Styx.

But I'm afraid to get lost in it and find no way out.

I'm even more afraid that after I die, I won't be able to face my grandfather, my father, and my uncles who are working hard for me.

That's why I lingered in front of this dark river for a long time.

He even probed around to see if there was any other way out.

In the end, I gritted my teeth, sorted out the package on my body, opened a bottle of canned beef, ate a round belly, and then sealed my mouth and nose with a natural water character, and slowly burrowed into the underground river.

The river is cold, but it's nothing to me.

And the river has a high oxygen content, and the natural water character filtration can also provide me with enough oxygen.

I didn't swim fast because I had to memorize the shape of the rocks at the bottom of the river, the speed of the water, the temperature, and even the changes in the yin and yang breath.

The reason why I remember these things is completely to leave a way out for myself.

If there is a dead end in front of this river, I can still go back the way I came, so as not to get lost in the underwater world.

But this time, Lady Luck seemed to favor me.

Because when I was in the water for about 20 hours, I found that there were many more eyeless strange fish around than usual, and I could see one in an average of a few hours.

There are even some other species of small fish on the side.

The temperature of the surrounding water gradually increased, and although it was still cold, it no longer had that biting feeling.

I was in good spirits and kept swimming.

I don't know how long it took, but suddenly a green light came from the dark waters ahead.

It was the first time I had seen the light of the underworld outside of the vicinity of the lava.

All along, I have been blessed with natural light characters in my eyes, so that I can see far in the dark.

Now seeing the glimmer of light under the water, my spirits are lifted.

At this time, a black shadow suddenly flickered underwater, and a javelin-like weapon quietly poked out from under the water, piercing my heart!
