The "every layer" of the Demon Sea is not a change in geography, but a change in time.

The so-called "third layer" where Xiang Nan is now is 90,000 years ago, to be precise, the Demon Sea 90,000 years ago.

Those three warriors all came from the 220th year of the Heavenly Desolation Calendar, which was 80,000 years ago, so the place where they came in would not be 60,000 years ago, but directly to 90,000 years ago.

The entire Demon Sea has come to the two hundred and twenty years of the Wuyuan Calendar, which is true, so the Demon Sea really only has ten layers, but the time structure inside the Demon Sea and the time structure outside the Demon Sea are not synchronized.

"We are now standing in the sea of demons 90,000 years ago. Mengdie pulled Xiang Nan and said, "Let's go!" It's too close to the exit, let's not delay on this straight path." ”

"Dong Wuxian has eaten too much spirit grass, and it will take dozens of hours to refine, but we also have to be just in case. ”

"Friend, take your leave. Xiang Nan said goodbye to the "ancients" with his fists, and immediately took Mengdie to the left.

Continue to move forward in a straight line, you will enter the ninth ring of the chain lock space-time zone, Xiang Nan does not have the key to the ninth ring at this time, and it is in vain to walk over, and he will not get any benefits.

The two of them, after crossing the tenth ring in a row, and after more than thirty altars, they were relieved, and the horizontal distance from the exit was three hundred miles away.

The altar in front of me is still arranged in a stepped shape, with a radius of kilometers, and the center is a palace building with a high ceiling of the altar.

"You don't have the strength, wait for me here, I'll get the key and come back. Xiang Nan greeted Mengdie, and left Xiaoque to protect Mengdie, and he walked up the steps.

As soon as he went up, the altar rumbled and shook, and then a passage opened under the steps, and a wolf came out.

Xiang Nan frowned, and said to himself: "Why should I wait for it, just rush up directly before the wolf behind me comes out." ”

Thinking of this, Xiang Nan ran wildly, and that kilometer radius was nothing to him at all.

But in fact, while running, he realized that things were far from being as simple as he imagined, and he didn't defeat the first trap wolf, that is, no matter how he ran, those steps would be extended indefinitely!

In the eyes of Mengdie outside the altar, she was curious, she only saw Xiang Nan "running in place" on the altar, so she said: "Good brother, what are you doing, could it be that you are affected by some hallucination?"

Xiang Nan looked back at Mengdie, couldn't help but smile bitterly, and told what he had discovered.

"Be careful!" the wolf pounced!" Mengdie hurriedly raised her hand and pointed.

Xiang Nan turned around with a knife, and slashed the trap wolf with one sword, and said: "The realm of this trap wolf is only the realm of Guiyuan Sanzhong, which is two realms lower than me. ”

In this way, when the wolf "died", its body shattered into fragments, and in the fragments, there was a bright metal ore.

Xiang Nan took a look, the metal ore was just the most common refined iron, and this thing could only create a spirit grade primary weapon at most, which was much worse than his own high-grade dragon blood knife.

Xiang Nan didn't even have the interest to pick up this kind of refining material, so he went all the way up.

After walking a hundred meters, the ground opened, and two Guiyuan triple trap wolves appeared.

"It's so simple?" Xiang Nan frowned, and with a casual knife, he slashed the two trap wolves, and the thing he dropped was still a small piece of fine iron.

Continue to move forward, and when you reach a position of two hundred meters, the ground opens, and four Guiyuan Triple Trap Wolves appear.

Xiang Nan swung his knife and slashed it, and then walked three hundred meters, eight trap wolves.

Xiang Nan discovered the pattern, every 100 meters forward, the number of trap wolves appeared was twice as many as the first 100 meters.

Even though these low-realm trap wolves did not pose any threat to Xiang Nan, the further back they went, the more they numbered!

At 400 meters, there are 16 trap wolves, 32 at 500 meters, 64 at 600 meters, 128 at 700 meters, and 256 at 800 meters!

By the time Xiang Nan reached 900 meters, there were already five hundred and twelve trap wolves!

This scene is already very shocking!

More than 500 trap wolves surrounded Xiang Nan in black pressure, which made people's scalps tingle at a glance.

Xiang Nanruo went to kill one by one, it was a bit too much of a waste of time, he directly released the dragon treading waves, and with one sword, the vitality condensed into a violent tornado, sweeping all the trap wolves into it, and in an instant, the fragments of the trap were scattered all over the sky.

The small fragments of fine iron all over the ground fell to the ground, and Xiang Nan was still too lazy to pick them up, so he stepped on the top of the altar.

At this moment, a stone palace in the center of the altar began to shake, and a wolf king who was three times the size of an ordinary machine wolf walked out.

"Returning to the Yuan Quadruple?" Xiang Nan nodded, he had already recognized the realm of this wolf king.

The wolf crunched all over his body and pounced on Xiang Nan.

Although these puppets have a realm, they can't release their vitality like humans after all, and they don't have demonic energy, they just use their own realm power to fight people.

Xiang Nan killed the wolf king with a single sword, and from its body, a small piece of superb fine iron fell.

Xiang Nan took the best refined iron in his hand and looked at it, and threw it away, this thing can only refine spiritual products and mid-level weapons, and outside, it can be bought with gold coins casually.

Xiang Nan lacks everything, that is, there is no shortage of gold coins.

And next to the best fine iron, there was a quaint key, Xiang Nan picked it up and walked down the altar, and said, "Okay, let's go to the ninth ring." ”

The two of them walked towards the center of the Chained Space-Time Zone, passing the Ninth Ring Road on the way.

"Did you find out. Mengdie said: "The things in this sea of demons, the realm is generally not much different from you. ”

"Do you remember the three warriors we saw earlier, and what kind of realm they fought the trap wolf? ”

Hearing Mengdie say this, Xiang Nan thought about it for a while and said, "I seem to have noticed that those three martial artists are all Guiyuan Quadruple, and the trap wolves they fight are only Guiyuan Quadruple." ”

That is to say. Mengdie raised two fingers: "No matter how high our realm is, as long as we break into the altar, the trap wolf of the altar will be two realms lower than you." ”

"When we were at the first level of day and night, the spider monsters we encountered were similar to yours. ”

"But when Dong Wushu fought the spider monster, he seemed to be very difficult, he was a master of the Tianyuan Fivefold!"

"Is it understandable that the realm of monsters in the Demon Sea will change according to the realm of the interlocutor. ”

"Well, that makes sense, I've been skeptical about it all the time, and your explanation is very reasonable. Xiang Nan nodded.

Only in this way can the Demon Sea have the value of breaking through, and if the difficulty of the mechanism left by the predecessors in the Demon Sea remains the same, it will be a bad thing.

For example, as long as they leave a monster in the Heaven Peering Realm on the first layer, then all the martial artists under the Heaven Peering Realm will all die.
