As the south water came in, his headlamp illuminated the space he entered.

Nanryukawa, who was walking in front, continued to move forward, and also put on a headlamp at this time. They had been here a long time ago, and they were all prepared.

I don't know if they ignored it, or if it was intentional, they didn't prepare anything for Shen Lang.

Shen Lang is now in the middle, but he doesn't need a light source, both of them can be illuminated in front and back.

Walking forward with the Nanliuchuan, it is a narrow crack, whether it is artificially excavated, or a natural gap, the years are too long, and it is impossible to see it at a rough look.

Shen Lang didn't care about this either, this was just an aisle, and he hadn't reached the location of the billions of rings yet.

Shen Lang didn't say anything or ask anything all the way, but in fact, his mind didn't stop.

He had looked at the map before, and he already had a general idea of his surroundings. Although it is turbulent when rafting in the back, it is also along the river, and the general direction can still be grasped.

Now that I have entered the mountain, I also have a map in my head. Even now walking along this gap, he is silently calculating the distance and direction.

This is not to make a note of their map trajectory and come back to it later, but just in case, if something happens or something, have a general direction and not get lost.

Although limited by the environment and limited speed of travel, they are still much faster than the average person overall, and there is no pause for a moment.

Finally, after walking for a long time, the front suddenly opened up.

What appeared in front of Shen Lang was a huge pit, and the crack they appeared on the middle stone wall of the giant pit, and the distance from the top to the top was about the same distance as the bottom of the giant pit.

Once here, the headlights of the two of them didn't work much.

One is that there is so much space here, and there is only a little bit of light to shine on.

On the other hand, there is a hole in the upper part of the crater, and light leaks in from the outside. The pit was obviously artificially created, and when the light came in, it illuminated a stone wall, polished like a mirror, reflecting the light.

The stone wall of the reflection point is refracted out, and so on many times, turning the light that cannot be turned into a light source.

No matter how ingenious the design is, it will be much worse after years of corrosion. However, it is not the first time that Nanliuchuan has come here, and it should have been re-polished to have a better refraction and reflection effect.

Of course, the key is to look at the light that shines in, and if it is just the right amount of sunlight, the effect is even more obvious. Otherwise, it's a little bit lighter.

However, they are not ordinary people, as long as there is a little light source assistance, they can see clearly.

"Billions of rings, this is here. Nan Liushui said slowly.

Shen Lang's eyes had already looked around this huge pit, in the eyes of ordinary people, this was a natural miracle inside the mountain, but in his eyes, there were traces of man-made transformation everywhere.

After Nanliushui made a start, he didn't continue to say, it also had the meaning of testing Shen Lang.

The teleportation array, the dragon arch beads and the dots can be found, which shows that Shen Lang has a great foundation in the formation. However, very few people have known about the Billions Ring Array since ancient times, and even many grandmasters may not have heard of it.

In other words, Shen Lang just got the ticket for their invitation to cooperate, and whether he can enter this door or not depends on the current test.

If Shen Lang didn't have the slightest understanding of the Billions Ring Array and had no way, then bringing him would be equal to zero, then even if they had already reached the gate of the array, they would still have to retreat. Otherwise, if you take Shen Lang in, you will still not be able to pass the road ahead, and you may be injured again.

Shen Lang understands this very well, and this is different from his competition speed, when he really wants to show his hand, it is directly related to whether this exploration can move forward.

Billions of rings!

While he was observing, Nanliuchuan and Nanliushui both had serious faces and did not make a sound to disturb him.

At this time, in their hearts, they all hoped that Shen Lang could show them a miracle.

But the unexpected happened to them!

Shen Lang only glanced at it a few times, and then jumped directly into the giant pit!

"Wait ......"

Nan Liushui wanted to open his mouth to stop it, but it was too late, Shen Lang's figure had already entered the giant pit and had already entered the formation.

He originally had the intention to follow, and if Shen Lang was in trouble, he could save people back, but Nan Liuchuan had already intervened to stop him.

"Don't be impatient, let's not disturb him, and see how he works, especially you, may be inspired. ”

Nanliushui thought about it right, so he didn't follow, but stayed above to look at the overall situation.

After Shen Lang went down, the speed was very fast, and the horse walked up.

From above, he looked like a headless fly, spinning around in a labyrinth with no route.

But the south flowing water can be distinguished, Shen Lang's body pace is very fast, and every route is traceable and regular. It seems to be out of order, but in fact it completely caters to the changes of the billions of ring arrays.

After looking at it for a while, he frowned and thought about it.

It's really inspiring, Shen Lang's way is completely different from his!

Because Shen Lang is here for the first time, and there is no information here, it is completely a new attempt, and the method used has a somewhat tentative taste.

But this is a kaleidoscopic ring array, one ring is wrong, and it will be more and more difficult to sort it out later.

Under his intently attention, Shen Lang actually relied on a quick temptation, and quickly figured out the way of this billions of ring arrays, and then smashed Huanglong, found the key point of opening the first level, and directly opened the portal!

"It seems that this kid really has two hits!"

Nanliuchuan praised it, although Nanliushui is more proficient in the formation, he also understands it, and he has been here more than once, so he has experience.

The two of them immediately flew down and fell directly into Shen Lang's side.

"Do you want to continue?" Shen Lang smiled teasingly.

Although it was the first time he faced this formation, the law was actually clear, and the cursory glances had actually grasped the key points from a comprehensive perspective, and the specific operation was only a detail.

Nan Liuchuan gave a thumbs up: "Go on! You really have real skills!"

"Xiaoyou's understanding of the formation is really insightful, and I should learn from you. Nanliushui also praised it.

Shen Lang said lightly: "Go on! The front will be more and more difficult, and we have to work together!"

The two of them have a deep understanding of this, Shen Lang is not modest and polite, but he sees the key to it.

The cracking of the second ring, Nanliushui still let Shen Lang come, but he assisted this time.

Shen Lang's strength has been proven, and letting Shen Lang make a move now is to add a little experience to him, so that he can understand more about the formation, and he can have more inspiration in the later levels.
