The world barrier at the very end, for the many monks in the Tianfeng Continent, this is a place that can neither be seen nor touched, and the only channel that can be understood is only a few words in a very small number of ancient historical books.

In today's Tianfeng Continent, there are less than thirty people who are really capable of seeing and touching the barriers of the world.

Of course, it's one thing to have the ability, it's another thing to have the opportunity to see and touch it.

The entire world of the Tianfeng Continent is in a "ball", of course, this is Liu Pan's current view. If there is a view of the overall structure of the world by the natives of this world, it should be "the sky is round and the earth is round".

The view that the sky is round and the place is round is not unfamiliar to Liu Pan, because the ancient Chinese science's understanding of the universe is that the sky is round and the place is round.

However, with the progress and development of modern science later, it took a long time for people on the earth to gradually realize that the place where they live is a sphere, and the heaven and the earth are not the structure of the world.

In the Tianfeng Continent, there are many marks on the world barriers in the ancient historical books, but in the long historical process, many points that are convenient for observing the world barriers have disappeared for various reasons.

Nowadays, there are only three places in the Tianfeng Continent where the world barrier can be clearly observed, which are in the extreme north of the Northern Plains, the extreme east of the Eastern Desolation, and the extreme west of the Western Desert.

However, although the three observation points are clearly marked, not many people can actually go there.

In the land of the Northern Plains, the further north you go, the cooler the temperature becomes, and the north of the deserted city is not a forbidden place that ordinary people who can't cultivate can set foot in.

Beyond the ice, it takes a monk who has mastered the power of space to stay for a long time. And if you go further north, even a monk who has mastered the power of space will not be able to stay for a long time.

The real extreme cold, even the space will freeze, only by controlling the power of the unity of heaven and man, can you draw strength from this extremely harsh environment for your own use, but if you stay for a long time, even if you are in a state of unity of heaven and man, you need to maintain your own consumption at a low limit.

Compared to the harshness of the extreme north of the Northern Plains, the environment of the two observation points in the East Wilderness and the West Desert is relatively better, but it is not a forbidden place that ordinary cultivators can set foot in at will.

All the way to the north, although it is not obvious, with the observation power of Liu Pan and the others, it is very easy to observe the changes in the surrounding space.

The land of extreme cold is really pure extreme cold, even the free ice system Yuan Qi in the air is rejected because of this extreme cold, and gradually becomes thinner, as for the Yuan Force of other systems, it is even more unbearable.

Edgeworth flew three days later, and Liu Pan and the three of them gave up the imperial weapon and switched to walking.

In the extremely cold temperature, the space began to become viscous, and if you continued to move forward, the consumption of your own yuan power would become greater and greater.

This is the realm where the Heaven and Earth Yuan Force is gradually becoming thinner. The initial consumption may be fine, but if you continue to go deeper, the absorption of vitality is lower than the consumption, it is undoubtedly not a good state for the monk.

However, although the three of them were on foot, the speed was not slow.

Ye Qing and Li Song are cultivators of the realm of martial saints, and although the space has become viscous, the impact on them who have reached the realm of the unity of heaven and man is actually not obvious.

As for Liu Pan, his physical body had already been fused with the power of space, and even if the space was completely imprisoned, it would not affect him in the slightest, not to mention that the space in front of him had only become viscous.

What really made the three of them scruple was that the vitality in the air was gradually thinning. In order to maintain the state of being in full bloom at any time, I chose to walk forward.

Time passed, and it was another three days of travel, during which Liu Pan and the three of them noticed the changes in the surrounding environment. It doesn't feel like it's on land anymore, the road is undulating like the waves in the endless sea.

The perception spreads, and the kilometers below your feet are also solid ice, and there is no trace of land soil at all.

The sea of ice is endless. Ye Qing and Li Song pulled the padded jackets on their bodies, and at this moment, they had already wrapped themselves in the appearance of a big stupid bear.

Although theoretically a strong monk can not be afraid of cold and heat, in reality, it is only by virtue of his own strong cultivation that he resists all negative states.

When the consumption is not large in ordinary high heat and low temperature, it is true that you can not be afraid or even ignore it, but if you are really in an extremely harsh environment, in order to avoid the waste of your own energy, you will still choose foreign objects to maintain your own state.

When I opened my mouth, I could vaguely see some ice crystal debris falling.

Ye Qing looked at Liu Pan not far ahead, although he had already understood that Liu Pan's physical body was the body of the legendary demon spirit and ghost corpse, but this attribute that was not afraid of cold still made him feel very surprised.

Looking at Li Song again, he couldn't believe it, after all, Liu Pan's clothes are still the same as when he first arrived in Beiyuan.

At the tip of the ice waves, Liu Pan is looking out. Liu Pan didn't feel strange about his own state, after all, he had been to Beiyuan at the beginning, and when his physical body was not strengthened to the extreme, he felt a little cold when he arrived at the Ice Domain. Now, the physical body enhancement is not what it used to be, and his perception of the cold has become numb even further, so he still hasn't felt much cold when he walks here.

The gaze extended, it was to the sky, Liu Pan had a lot of inexplicability in his eyes, in fact, he could have seen it as early as a day ago, because there was a dazzling luster extending to cover the end of the entire horizon, and it was difficult not to see it!

According to the relevant records of ancient historical books, it is an undulating mountain of ice shining in the sunlight.

I rested and ate a lot of food. If it weren't for the extraordinary speed of action, Liu Pan and his party are really no different from ordinary people now.

Traveling to the depths of the extreme north, the viscosity of the space has been further improved, and if you control the weapon here, not only will it consume a lot, but even the speed will not be half of the original normal.

Moreover, because of the rejection of the extreme cold, the Heaven and Earth Yuan Qi here has already thinned to the point where it is almost impossible to absorb, and it has almost reached the realm of unilateral consumption and no replenishment.

Therefore, Liu Pan and his party chose to pause and set off again after taking a rest.

It might be a little unbelievable to say it, because most of the physical strength supplies of Liu Pan and his party now come from food, which is almost impossible for a high-level cultivator. But now, it is a little bit to be able to save.

All the knowledge about the world barrier at the end of the Northern Plains comes from ancient historical books, and Liu Pan and the three of them have not seen it personally, so seeking stability is the best choice for the three of them.

Wangshan ran a dead horse, especially when Liu Pan and his party could only move forward on foot.

Moving forward day and night, walking and stopping, it was also fortunate that the cultivator's exuberant energy was not affected here, except for eating, Liu Pan and the three of them did not need to delay time to do anything else, and finally in the evening of five days later, the three of them arrived at the place of the mountains of the cold and extremely icy regions.

The sunset is soft, and the light sprinkled makes the cold polar ice covered with a layer of bright orange red, which looks extremely beautiful. As far as the eye can see, whether left or right, this mountain is like a beautiful band of light spreading to the end of the distant sky.

However, it is a pity that such a beautiful mountain scenery is not something that ordinary people can afford to enjoy, and those who really come here are not in the mood to calm down and enjoy such a beautiful scenery.

Standing under the icebergs, Liu Pan and the three of them raised their heads, and as far as they could see, the icebergs and mountains were towering into the sky. And in fact, the iceberg has really touched the sky.

According to the description of ancient historical books, the extreme icebergs of the Northern Plains stand against the sky, and not only its peak touches the sky, but even the whole behind it is a piece of sky.

No one can climb over the mountains formed by the polar ice in the cold region, this is not an exaggeration, but this extreme iceberg does not have the side behind it at all.

"Big brother, are we going to climb the mountain or open a cave next?" Ye Qing spoke, and as he spoke, his gaze shifted from the mountains to Liu Pan.

As for Li Song, his eyes also fell on Liu Pan when Ye Qing asked.

Climbing a mountain or digging a hole, that's a problem.

If you want to observe the world barrier at the end of the world, you either need to climb the mountain or open a hole. Of course, there is another option, and that is to follow the extreme iceberg until you reach the end of the mountain.

However, it is too time-consuming and laborious to walk along the mountains, and at the end of the icebergs is the Wild Sea, a barren sea that has never been set foot by humans, and the degree of danger is unpredictable.

"Mountains must be climbed, and holes must be beaten. Liu Pan opened his mouth, there was inexplicability in his eyes, and while speaking, he also raised his foot, and walked straight to the foot of the mountain not far from the side, and said: "Our luck is better, there is a cave left in the depths of this nearby mountain, and it is only about 800 meters away from the cold ice. ”

Hearing Liu Pan's words, Ye Qing and Li Song were stunned at first, and then their eyes lit up.

Ye Qing and Li Song did not doubt what Liu Pan said, of course, they did not have the qualifications and strength to doubt it.

Eight hundred meters of cold domain extreme ice, as far as ordinary monks are concerned, their perception cannot be explored in depth at all, even Li Song, who recently stepped into the middle stage of the Martial Saint Realm, is extremely suppressed here, and can only detect about six hundred meters of cold region extreme ice.

As for Liu Pan, his perception was also suppressed here. In a normal environment, Liu Pan's perception is nearly four thousand meters away, but now it is greatly discounted when he goes deep into this cold ice, and he has less than one-third of the detection distance.

However, fortunately, Liu Pan's perception was sufficient, and there happened to be a cave left by his predecessors in order to observe the world barrier nearby.

The caves left by the predecessors may not be able to find many traces in the history of the time between thousands of years and 10,000 years ago, but if it is in the history of 10,000 to 100,000 years ago, there are many more people in the Tianfeng Continent who have the ability to approach the Northern Plains to observe the world barriers than now.

The reason why the cave is left behind is because although the Extreme Source Ice is full of cold, it will still isolate the humidity of the extreme cold.

To put it simply, it is to dig a deep cave in the solid ice of this northern plain, and after a long time, a distance at the entrance of the cave will be frozen again due to the entry of the damp and cold breath from the outside, but the depth of the cave will not freeze because the damp and cold breath is too little, and it will remain in a closed state.

Liu Pan didn't know who had made this cave in the first place, but obviously, it had helped him a lot now.
