I don't know what is under the big pit, but there is a little bit of light in it, it looks like there is a large group of fireflies inside.

But Chen Feng knew that it was not a firefly. At this time, Cheng Zhixue also explained.

"According to the record in the Spiritual Bureau, those lights are a special kind of creature under the pit. After death, they may be stained with some spiritual energy, so they can shine. As for why he floated up instead of sinking, this I have no way to explain, it should be something underneath that can make them float up!"

Spirituality is not a panacea, so Zhixue doesn't know everything, but it's not bad to know at all.

Chen Feng didn't delve into it. The most important thing now is how to find those two people.

He was pretty sure that the two of them didn't come out again after they entered, so there must be a road ahead, just don't know where the road is.

Immediately afterwards, Chen Feng observed this tiankeng.

There seemed to be no stairs in front, and he didn't think they could go directly through the big pit.

In fact, this is not possible.

In thinking, Chen Feng's inspiration flashed.

Perhaps it is not that there are no stairs as he imagined. The stairs are invisible. People who have never been here naturally think that there is no way.

Chen Feng had already prepared before. He took out a can of silver powder from his pocket and sprinkled it on the front.

After a while, a transparent spiral staircase appeared, leading straight down.

From the top down, the stairs seem to be very long, and I don't know where to go, and only one person can walk over it, which looks very fragile.

Just seeing this staircase is enough to startle some people who are afraid of heights.

In addition, Chen Feng felt that the stairs were very rotten.

"The copywriting in the bureau here is also recorded. Don't worry, the stairs are very strong."

I don't know if Cheng Zhixue saw Chen Feng's worries, so she took the lead and walked towards the stairs. After a few steps, she turned her head and looked at Chen Feng with a smile.

Before Chen Feng had any reaction, Zhixue stomped on the stairs abruptly.

She might have done this to verify that the stairs were safe, but she didn't know why, but she did this to make Chen Feng even more worried.

But Chen Feng followed.

After all, if you want to find the evil spirits, they can't stay here forever.

Mainly because there is no other way, Chen Feng has no choice.

Walking on the stairs, Chen Feng thoughtfully.

The emergence of this spiral staircase should be time-limited, and the evil spirits and Hu Zhangye should also go down here.

When Chen Feng and the others came over, they just disappeared.

This spiral staircase is very long, and the time to go down is about the same as the time to walk in from the cave and into the tunnel.

This also let Chen Feng know how deep the big hole is.

If you accidentally fall from above, it will take a lot of time to fall to the ground.

Of course, after falling to the bottom, it won't look like an adult.

Standing on the side of the stairs, Chen Feng looked around.

Let alone other things, the scenery here is still beautiful.

When I stood in front of the pit, I saw the lights as if they were fireflies.

When you get to the stairs, when you look up from below, the lights are like stars.

It's a pity that Chen Feng and Cheng Zhixue don't have time to appreciate these things, because they have to catch up with the evil spirits.

Because the spiral staircase is relatively long, the evil spirits and Hu Zhangye didn't get too far away from Chen Feng.

When Chen Feng came down, they happened to see their backs.

But I only saw a trace of his back from a distance, and only a small shadow was seen.

They are not close to us.

Even if you speak here, you should not be able to hear it over there.

Chen Feng was slightly surprised.

There was such a large space underground, which really surprised him, so he couldn't help but believe the rumor that there was a spirit mine before.

Generally speaking, mines are on the mountain, and they are very large, but the spirit mine is just the opposite. It is underground.

After all, in the spirit mine, what you possess is spirit energy, not those ordinary stone mines.

The following was a smooth journey. With the previous experience, Chen Feng didn't lose patience, but he was curious how long it would take to reach his destination.

I don't know if Chen Feng felt bored and angered certain existences. Soon after, they encountered the first difficulty.

That is a barrier.

At this time, Chen Feng and the others were at a corner of a mountain. Walking straight ahead, they could see a blood-red barrier, and there were two people in front of the barrier, trying to solve the problems they encountered.

It's not that evil spirits and Hu Zhangye will have anyone else.

From their attempts to lift the barrier, Chen Feng knew that their previous embarrassment was caused here.

Cheng Zhixue knew more than Chen Feng, and she slowly explained it in a low voice.

"That is the blood evil spirit. There is a magic circle set up by someone with his own blood, but the circle of that magic circle is at the innermost point. You won't find it if you don't enter.

"From the surface, it looks like a barrier. As long as you touch it and there is no correct way to enter, you will enter the formation and be trapped."

"These two guys obviously know something, so they didn't touch the blood evil spirit, so they haven't entered the formation yet."

Cheng Zhixue explained to Chen Feng while looking forward.

Hearing this, Chen Feng couldn't help but glanced at her twice.

She is much better than she thought.

Although I'm just explaining some things now, it's great to be able to know those things.

Blood Fiend, this Chen Feng has naturally heard of it. If you want to get rid of it, it is difficult to say, but easy to say.

If you can find the blood of the person who set up this blood evil, it will naturally not be difficult to remove this blood evil.

Of course, if you can't unlock it, you won't be able to go in, and if you attack with magic, you will be bounced back.

But this blood evil seems to have existed for a long time, and the arranger must be gone.

Where does this get that person's blood?

And there is one more thing, that arranger must be very powerful, so even if he has his blood, it may not be able to be relieved.

After all, I'm afraid that this person will leave behind dark hands or steps to release. The step difference is a little bit. Not only may it not be released, but it may also be attacked by formations.

Thinking of this, Chen Feng couldn't help but squinted.

Hu Zhangye and the others don't look like they can be cracked, but they have been here several times before, and they still haven't given up. That shows that they are determined not to give up, and perhaps they have found a solution.

"What shall we do next?" At this time, Cheng Zhixue asked in a low voice.
