The fact that Nanliu was able to find the entrance and exit should be related to the information left by their ancestors who knew the inside story.

But Shen Lang wasn't worried, if he just told him that there was such a place, in the whole world, even to the waterfall, he wouldn't be able to find such a deep entrance.

But now that he is inside, if he is just looking for an exit, the scope is greatly reduced.

For the carpet search up and down this huge pit, Shen Lang did not need to go through them one by one, but searched in all directions with his divine sense.

The search was quickly completed, and in addition to that one crack, there were many cracks in the surrounding stone walls. I don't know if it's the relationship between the mountain compression, or the trick that was laid out at the beginning.

What he needed now was to try one by one to see if the exit would be in one of the cracks.

The first crack was not far from the end of the crack, and after careful investigation, there was no mechanism.

The second crack is too small for people to enter, and it is also a very short section for the divine sense to probe.

Third, fourth......

checked one by one, and all the cracks were "dead ends". The longest stretch is the crack at the entrance.

However, Shen Lang was still not discouraged, he locked the hole of the light above!

This place is exquisitely designed, borrowing the continuous refraction of a light, so that this huge pit in the belly of the mountain, which should be black and rumbling, has a little dim light.

Since there is light to let in, it means that the hole is outside the mountain.

Even if there is a cliff outside, as long as he can get out, he can land safely, and even if the hole is not big, he can still dig it out with brute force.

After the crack was checked, Shen Lang flew to the hole of the light at the sloping top.

Because the pit is very large and very high, whether it is below or in the middle, the hole is very small. Now I flew up, but I found that it was actually the size of a washbasin.

With this size, people can drill out, even if the top is getting smaller and smaller, Shen Lang will use the Juyue Sword to stab it bigger!

But......

He didn't have time to rejoice, but when he got closer to the hole and took a closer look, he found the mystery!

It's not a hole leading to the outside of the mountain, it's just a few feet deep. In fact, what is inlaid inside is a piece of luminous ore similar to the one in the Ice Palace, and inside, a bronze mirror is placed, through which the bright light is reflected to other reflection points on the mountain wall.

Because the light of this ore is not strong, it does not look like direct sunlight, but like natural light from outside.

In addition to feeling "trapped", Shen Lang also admired this senior even more. Just one piece of ore serves the purpose of illuminating the entire crater (although it is actually very dark), and it is arranged so naturally.

But now, it has increased the difficulty for him, and if he carefully identifies it, there is no road or other mechanism except for ore and bronze mirrors, and it will go straight to the end.

Shen Lang could only concentrate and searched the entire giant pit cave from the beginning.

It turned out to be nothing!

Could it be that the key point is to return to the billions of rings at the bottom of the giant crater?

Shen Lang put away the thought he had just put away and began to think differently. Since you can't find the mechanism and exit, what about looking for the traces of the two people in the south and the south?

In fact, it's not very optimistic, if they had left after cleaning up the Iron Armor Red Dragon, it would have been a month, and all traces would have faded.

And there are stone walls all around, and most of the places will not stop accumulating dust, so I want to check whether there are any traces of being pressed in them. If you really need the method of the police fingerprint group, the amount of work is also huge.

Shen Lang changed his mind again and let himself return to the original point!

The origin is the way you came.

Shen Lang remembered a detail, when the underground river washed into that space, Nanliushui did not directly find the mechanism at the crack in the stone wall, but after opening the mechanism, let them go in first, and then hurry up and come in by himself.

And just now he walked to the gap blocked by the stone wall at the end, what if the mechanism opened was in the middle of the passage of this crack?

Now he's searching the agency right from the entrance.

According to the style of that senior, no matter which level, the time left for them to enter and exit is very short, maybe the real mechanism is designed in front, and it needs to be pressed by one person, or run to get out.

With this line of thought, Shen Lang not only checked the traces, but also pondered from the perspective of the array, slowly checked the surroundings step by step, and then moved forward.

It's slow, but it's also impatient.

Not at the entrance, not in the middle!

After walking for more than half of the walk, he still didn't find any traces, which made Shen Lang can't help but take a deep breath to stabilize his emotions.

Finally, when the end could be seen, Shen Lang discovered a suspected mechanism!

Although Shen Lang didn't know the order, with his understanding of the formation, he even cracked the hundreds of millions of ring formations, but he still quickly mastered the rules and immediately opened this mechanism.

I felt a tremor in front of me, and then the huge stone wall began to move slowly.

This time, no one pressed it, and Shen Lang was not bad at this patience, so that it was almost completely opened, and then he let go and rushed out to the gap.

In fact, the crack in this huge stone wall that is completely open, that is, the size of the passage inside, is good through one person, and it is squeezed by two people in parallel.

So he actually had to pass through this section before the crack was halfway closed again, otherwise people might be squeezed, although it wouldn't be stuck, but if it was delayed a little time, the space would be narrower and more difficult to pass.

With Shen Lang's speed, of course, there is no problem with this, after all, even Nanliu Water can be completed.

After coming out, he hung in the water and watched the stone wall slowly close back. Shen Lang was a little embarrassed, being able to arrange such a mechanism means that at least this villa-sized boulder is cut off and used, this is in the belly of the mountain!

Looking at the surrounding space, it is estimated that it should also be artificial.

Shen Lang took out the previous piece of wood from the space bracelet, and then bent down and went upriver in the groundwater.

Before, it was down the river, but in this underground river, you need to pay attention to the rocks on it, and the exact direction and location of the stop.

Now, in addition to paying attention to these things, you must also accelerate forward directly against the current, and there are no companions, and there are no headlights, this is already a month ago, even if you walk through it in the middle of the dark, it is still a little difficult.

However, compared to the clueless search for the exit mechanism just now, it is much easier now, and it can be done with a little care.

After sneaking against the current for a while, Shen Lang felt bright!

Although there are still dense jungle branches above, when they come out of the darkness of the underground river in the belly of the mountain, they appear bright, and they can put away the glowing ore and speed up the up.
