After the third ring was cracked, they had already left the giant pit, and according to the distance they walked, it seemed that they had gone a lot deeper into the ground, but the specific environment was unknown.

When he came to the fourth ring, Nanliushui stopped Shen Lang.

"The last time we came here, it was at this fourth level. But it's full of dangers, can you be sure?"

I didn't encounter any more mechanisms along the way just now, it should have been their previous intrusion, cracked one by one, or consumed.

And the danger after the fourth ring was still not consumed, because before they broke in, Nanliuchuan had already been injured and had to retreat.

Shen Lang smiled: "I don't dare to say that I am sure until I see it with my own eyes." However, the seniors have already had an experience once, so it should be easier this time!"

Nan Liushui hesitated for a moment: "Do you think it's better for me to open it, and it's better for you to assist your brother, or continue to open it?"

Shen Lang immediately understood the entanglement of Nanliushui, and hoped that he would have a way to pass without any crisis, but he was afraid that there would still be danger.

If this is the case, Shen Lang opens the formation, he is afraid that in case, then their brother's life will be in Shen Lang's hands. But if he came, he was afraid that Shen Lang would not be able to help Nanliuchuan.

"I'll do it anyway! If you do, it's business as usual. ”

Shen Lang said it very simply, but the meaning was very clear - Nanliu still can't do it!

This made Nan Liushui listen, and he was naturally a little unconvinced, after all, he was the most proficient in the formation of the Nantian family, and he was also a rare formation master in recent generations.

However, Shen Lang has already proved his strength by opening the first three levels before.

Nan Liushui took a breath and arched his hand: "Then there is Lao Xiaoyou! My two brothers will rely on you!"

This was somewhat solemn, and it also revealed a trace of his worry.

In the final analysis, they are only one side of the relationship with Shen Lang, and they will make up their minds to choose him because of the lack of formation talents, and it is inconvenient to find other formation masters.

But trust has not yet been established, and anyone can guess that there must be a treasure in this hundreds of millions of ring arrays. And treasure is the easiest thing to be greedy!

Admittedly, a share may be enough to make a profit, but if you can have a share, who wants to share it?

Nan Liushui changed himself to open it, and he had more or less such an idea to ensure that the two of them had a control over the situation. Now let Shen Lang come, in case they are used as cannon fodder......

Shen Lang smiled: "Don't think about it so much, I don't know what is in this billions of ring arrays, I need to work together even more in the future, how can I be an unreliable person?"

His polite statement made Nan Liushui's face embarrassed.

Shen Lang didn't talk any more nonsense, went over directly, and opened the formation of the fourth ring.

When he first came over, he already knew in his heart that the fourth ring was not isolated, and the third ring that had been opened and the fifth ring behind it would be related.

So if you want to open it safely, you have to do it at the same time!

In fact, strictly speaking, each link is related to the other. So after they went out, they came in again to reopen, and the formation was not cracked.

This point was discovered, and when the third ring was opened, the problem of the fourth ring was already taken into account.

As for the first three rings, it didn't show up, because it was already known that the mechanism was ineffective. The formation can be closed by itself, but the trap mechanism can't - for example, poison arrows, no one makes up for them after shooting, and naturally there will be no more poison arrows next time.

Now it's the fourth ring, the last time I went to Nanliuchuan, I was injured, and for the sake of the old face's face, Nanliuchuan didn't say anything in detail until now, and Shen Lang had to take care of it.

When Nanliu Chuan Nanliushui was ready, Shen Lang began to open the formation of the fourth ring.

Nan Liushui can see it clearly, his steps are exactly the same as his own, and there is nothing unusual about it!

And he himself proved that it was okay to start like this.

Now, I don't care about it so much, the two old brothers are ready, and when the formation is opened, they will rush in immediately and grab time!

At this time, Shen Lang disappeared all at once!

This surprised both of them, they disappeared at this time, could it be that the kid found out that there was danger and ran away first?

Just when they were searching, they found that Shen Lang's figure flashed again, and he actually retreated to the back.

When they were inexplicable, Shen Lang completed the last step and quickly went in first!

The Nan brothers glanced at each other and hurriedly followed.

They were a little glad in their hearts, it was dangerous to enter the fourth ring, and the two of them were not absolutely sure together. Now Shen Lang rushed in, no matter what the purpose was, it was to attract firepower for them.

But when they followed in, they were stunned in surprise.

Shen Lang did not encounter danger, and they did not encounter danger either, but saw Shen Lang standing calmly.

"It's ...... What's wrong?"

"How so?"

Shen Lang looked at them and smiled: "I don't know what the danger you encountered last time was, but to skip this ring, you must start three, four, and five rings at the same time!"

Nanliushui is an expert in the end, and he was immediately inspired.

At the same time, this is like a mobile phone multi-touch, but it doesn't have to be absolutely at the same time, there should be a buffer time, as long as it is completed within that time, it is considered to be completed at the same time.

It's like when he comes in, he completes the final maneuver, finally lets go, closes up on the stone wall, and has a little time, as long as he can get through, there is no danger.

"There is such an operation...... "Nan Liushui sighed a little.

It's not the first time they've come, and after they went back, they kept deducing it over and over again. I didn't think of such a linkage, but thought about how to speed up and avoid dangerous mechanisms.

I didn't expect to "turn on the lights on the fourth floor, go back and press the lights on the third floor, and speed up to press the lights on the fifth floor"......

"That means that we can all open the next ring in this way?" Nan Liuchuan was excited.

Shen Lang provided a good idea and made him realize the feasibility.

"So, as I said earlier, we need everyone's concerted efforts in the future. I just tried this idea, and in order to succeed, I had to do it myself. ”

"Please!" Nan Liuchuan hugged his fist at Shen Lang, obviously respectful.

Even the plan that everyone didn't expect of his brother's formation, Shen Lang not only discovered it, but also proved it, which can be seen.

The south flowing water is shaking the speed of Shen Lang!

It's not as simple as holding down three keys at the same time, it's about manipulating the fourth ring, going back to the third ring, coming back to the fourth ring, and then rushing past the fifth ring!

"Shen Lang Xiaoyou, Nan admires!"
