Xu Nian followed Lin Ruolan all the way north, and soon arrived at the entrance of the Northern Desert.

"There is a Gobi in front of you, do you know where they went?" Xu Nian asked as he looked at Lin Ruolan beside him.

"Yes, I've been here before, and I've had the pleasure of meeting the so-called Asgard, and if I'm right, they should have gone there. Lin Ruolan looked at the immortal palace in front of her and said.

"Immortal Palace? Is there really a Immortal Palace? Could it be that there are also immortal tombs in this Northern Desert?" asked Xu Nian in surprise.

Lin Ruolan laughed when she heard this.

"How can there be so many immortal tombs, the fairy palace here is just a natural small world, when the sun becomes strong, the barriers of the small world will become thin, standing on the desert of the northern desert, if you are lucky, you can also see the scene inside the small world, so many people see the so-called fairy palace in the northern desert, but they can't get close to it, it is for this reason. Lin Ruolan said with a smile.

"A natural little world?" Xu Nian looked surprised.

"Yes, there will be many variables in the evolution of the universe, this natural small world may be a small pimple growing out of the ontological universe, this pimple is very common, not enough, but some natural small worlds are stable, and some are easy to collapse, their small world is obviously a stable small world, and the predecessors seem to have entered it. Lin Ruolan explained.

Xu Nian instantly understood how this small natural world was formed.

"Then is this small world affected by this Immortal Emperor's prohibition?" Xu Nian thought for a while and asked.

"Of course not, that small world can be said to be a world of its own, and not only that, but your perception may not be able to be used in that world. Lin Ruolan said with a smile.

"How can this be?" asked Xu Nian, puzzled.

"It's very simple, this small natural world is actually not the ontological universe, it is a small world of its own, and the mystery of the law is naturally different, and the mystery you perceive is just evolved according to the laws of the ontological universe, and if the law of the small world changes, your mystery will naturally not be usable. Lin Ruolan explained again.

Xu Nian suddenly realized.

I didn't expect that there would be such a place in this Celestial Scar Star Field.

"Then you're going to this small world, I'm afraid you have another purpose. Xu Nian looked at Lin Ruolan and asked.

It is impossible for Lin Ruolan to do meaningless things, and it is even more impossible for her to come to help him.

The reason why I say this must have other purposes.

"That's right, the small world is a world of its own, and there are naturally things in it that this world does not have, and these things are likely to be supreme treasures, of course, the most important thing is the heart of the world of this small world, which is the priceless supreme treasure. Lin Ruolan said with a smile.

"The heart of the world?" Xu Nian asked in surprise.

"It's really stupid, I really don't know how you cultivated to the Earth Immortal Realm, you don't even know the heart of the world, no matter which world will have the heart of the world, and the heart of this world is extremely precious, because only the heart of the world can create a new space, if I can get the heart of the world of this natural small world, then I can refine it and refine it into my own small world, and those treasures in the space are all refined by relying on the heart of the world. Lin Ruolan said with a smile.

"Then if you take the heart of the world, will the small world be affected?" Xu Nian asked after thinking about it.

"There will be some impact, but it will not collapse, the whole small world will gradually dry up, so that it will eventually decline, this process is extremely long, even the smallest small world will take a hundred years. Lin Ruolan said.

Xu Nian was stunned.

In this way, it is okay not to take away the heart of the world, and the whole small world will collapse.

The creatures in such a small world would not have time to escape even if they wanted to.

"Let's go, what we need to do now is to find the weakest place of this spatial barrier, and then forcibly split the barrier and enter the small world. Lin Ruolan dropped a word, and then took the lead and swept forward.

Xu Nian immediately followed.

Now he kind of understood why Lin Ruolan was waiting for him here.

Because he has mastered the mystical laws of space, his perception of space is hundreds or even thousands of times stronger than that of ordinary people.

If you want to find the weakest place of this spatial barrier, you can only rely on Xu Nian.

Otherwise, if you want to find the weakest place in the spatial barrier, even a strong person in the Yuan Immortal Realm may not be able to do it.

The two of them were hurrying through the desert of the Northern Desert, and the yellow sand in the sky could not pose an obstacle to them at all.

Even if he encountered a storm, Xu Nian only split it with a sword.

"Found it!" Xu Nian suddenly shouted.

Lin Ruolan immediately stopped her figure and looked around.

"Here, the space here is extremely weak, and there seems to be only a thin film, and behind this film should be what you call a natural small world. Xu Nian pointed in one direction and said.

Lin Ruolan didn't say a word, she directly sacrificed a sharp sword and slashed it down.

The sword light was as sharp as a thousand rays of light, and the next moment the space was torn apart.

And behind this spatial rift is not a spatial turbulence, but a strange world.

Billowing strange energy poured out of the cracks, revealing a strange aura.

Seeing the scene behind the crack, Lin Ruolan was immediately overjoyed.

"Let's go!"

The next moment, Lin Ruolan swept directly into the spatial crack.

Xu Nian also followed, but he was a little surprised in his heart.

The energy of this natural small world is not an aura, but a gray air current.

There was a deathly smell of this air current.

Xu Nian tried to run the "Danhai Seed Blue Lotus", and with the injection of this gray energy, Xu Nian found that his immortal body refining speed was actually twice as fast as in the outside world.

"Curious energy!" Xu Nian walked through the spatial crack with surprise and came to this strange world.

The scene that caught their eyes made Xu Nian and Lin Ruolan a little surprised.

The mountains and trees here are extremely lush, but the trees and mountains here are different from the outside world.

All the trees here are silver-gray, and even the surrounding rocks are gray.

The whole world was gray, and the heavens and the earth were filled with this gray energy.

It's as if there is only one color in heaven and earth.

But fortunately, the river here is not gray, but the same as the outside world.

"This is a strange energy, this kind of energy can strengthen the soul power, haven't you yet reached the late stage of the Earth Immortal Realm? Lin Ruolan said with a smile.

Xu Nian was stunned for a moment, and immediately tried to absorb this gray energy through his soul.

As the gray energy poured into his Mud Pill Palace, the soul that had been stagnant finally improved at this moment.

"Well, it can really improve soul cultivation. Xu Nian's face immediately showed a look of great joy, and he began to frantically absorb these gray energies.
