It's slow to come in because the passage isn't straight.

The two were afraid that they would accidentally touch some mechanism and expose their whereabouts, so they were always cautious and did not hesitate to slow down the speed of exploration.

Now that there is no scruple about retreating, the two of them retreated in only half a minute.

Yang Yan had already tried it, and the light curtain had no reaction to the dead thing.

Yang Yan and Aotian suppressed their vitality, blood, and body functions, and everything was not a problem.

However, there is still residual vitality or vitality in the surface skin.

It is very likely that the alarm system of the light curtain will be triggered.

And at this time, just cover the whole body with ice cubes.

When they reappeared in front of the light curtain, there was already an extra curtain of water on the two of them that wrapped their whole bodies.

Without too much hesitation, the two passed the light curtain smoothly one after another.

After entering, the two looked at each other and smiled, and the water curtain fell off directly, and in an instant, it evaporated into water vapor.

Although Yang Yan and Aotian have high strength, they still do not leave any mistakes.

Because they know that the slightest flaw will become a possibility for them to be exposed.

With their self-confidence, of course, such a situation will not be allowed.

This passage is very strange.

First from wide to narrow, then from narrow to wide.

And slowly, the eyes suddenly opened up.

The two of them hid their bodies and looked inside.

This is a large iceberg interior space.

It can be seen that this is artificially excavated.

It's so big that it's almost half of the inner belly of the iceberg.

It was empty, but torches were already illuminated.

Strangely, in addition to the passage, there is also the shadow of ice.

Inside, just like a normal cave, there are stone walls everywhere.

This also guarantees that the torches do not melt the ice.

Even under the feet, there are stones.

However, Yang Yan could sense that it was not a real cave inside.

The depths of these stones, the periphery, are still ice.

This place must have been dug out and built with stones that had been brought in.

Otherwise, there is no way to explain why this is the case.

The two of them did not find the shadow or breath of the person, and naturally continued to move forward.

It's quiet and eerie.

Observed for a moment, but did not make any movement.

Yang Yan was now behind a large raised mountain wall, and his whole person was perfectly melted into the darkness.

As far as the eye can see, this is a large space.

There are a lot of sacrificial bronze ornaments, but they have obviously not been used for a long time, or not at all.

Because everything seems so clean.

Under the light of some torches, the place still looked a little dark, but Yang Yan could see the carvings on those huge bronze objects.

It was a dense crowd of angels, and the sky depicted an angel with nine wings.

His gaze indifferently examined everything below.

Another huge bronze vessel depicting a scene of sacrifice.

No matter what kind of scene it is, these all have the same place.

That's all birdmen, the angels of heaven.

Angel popular sacrifice?

Strange!

Although Yang Yan was puzzled, he didn't think much about this issue, he looked around, and there were no living creatures here.

In his perception, deeper down, there were more than a dozen black-robed people he was familiar with.

And, there was a faint smell of blood lingering on the tip of his nose.

Walk.

Glancing at Aotian, Yang Yan rushed out, and Aotian followed.

The two of them are like shadows, and they can't make any sound, which is the terrible thing about them.

It is impossible to imagine how many people would have died if these two men were killers, and their reputation would have been created by this.

Not long after turning forward, the two of them stopped together.

What is it?

Here, it has been opened up so high!

Looking further underneath, there is no bottom.

And it is dark again, and there is no light.

However, Yang Yan could see the scene in front of him, and he could also feel that the dozen or so black-robed people were doing something below.

Moreover, when I came here, the smell of blood lingering on the tip of my nose became more and more intense, and it was simply rushing to my face.

There is no ventilated place here, but there are bursts of cool breeze swirling and sweeping here, as if passing by Yang Yan from time to time, which is a kind of coolness that goes deep into the bone marrow.

You know, Yang Yan can walk on the ice field at that level outside, and he can walk like a normal environment, but this place is so weird?

I can't see the head at the top, I can't see the bottom at the bottom, in front of me, I really see it, Yang Yan can see what this thing is!

It's a huge building, oh no, it's not a building, or rather, an object!

The whole body is made of bronze, from top to bottom, layer after layer, spiraling down the slide.

It's like a kindergarten slide.

It's just that this is made of bronze, and this bronze slide from top to bottom is very narrow, not to mention sitting down a person, it is barely enough for Yang Yan to stuff a fist.

The chute is rounded and neat, like a huge, rigorous work of art.

This thing, even if it is made with the best technology in modern times, does not know how much power it will take.

At the very least, the investment is very time-consuming.

Below.

At this time, Aotian beside Yang Yan stretched out his finger and pointed underneath.

Just tell Yang Yan that the dozen or so black-robed people are down there, do you want to go down and take a look?

At this time, he couldn't see the situation below, and Yang Yan didn't want to move.

With their strength, looking down is also bottomless, after all, there is no light, and it is very good that they can see tens of meters.

Wait.

After Yang Yan expressed this meaning, he actually hid directly in the shadows, and then stood like a statue.

If Aotian hadn't been looking at him, he would have thought that Yang Yan was gone.

At this time, Aotian also did the same, and hid on Yang Yan's right.

Time passed slowly.

To be honest, in such a silent space, it is difficult to perceive the passage of time.

The two of them controlled their breath and almost completely blended into their surroundings.

They waited silently for an unknown amount of time.

At this time, the temperature drops suddenly, and the blood flowing in the veins has a feeling of being frozen.

At this time, Yang Yan could clearly see a large cloud of white mist appear in front of him.

In other words, everything in front of him has been completely covered by white mist.

Then there was a faint glow of fire.

The temperature suddenly pulls back at this time, which suddenly makes people feel a sense of dire straits.

Yang Yan's expression was as usual.

He calmly watched what was happening in front of him.

If he didn't guess wrong, all the mysteries would be solved.

Suddenly, a slight murmur came into Yang Yan's ears.

What followed was a rush of blood.
