Digging caves is time-consuming and laborious. Fortunately, Liu Pan and the three of them are not very human, and the excavation tools they use are not ordinary.

It lasted two days, and Liu Pan and the three of them took turns to fight, and finally dug up the ice isolation of more than 800 meters at the cost of six lower-grade holy weapons, two medium-grade holy weapons, and one high-grade holy weapon, and successfully entered the remaining cave of their predecessors.

Of course, the main reason why it took two days was to save effort, after all, you have to climb the mountain to check it later, if you are reckless, even if there is only one person, it will not take half a day to dig up the 800-meter-thick ice.

Liu Pan was also glad that Ye Qing and Li Song's attainments on the way to refining weapons were not low, and they had refined a lot of things when they were idle in the past, otherwise it would be really difficult to get this solid ice layer in only two days.

In the final analysis, the ice thickness of the entrance to this cave was far less than 800 meters when it was completely frozen at the beginning, but as time passed, the cold air from the outside world fell on the iceberg and the mountain grew stronger and stronger, and it is only now that there is finally this 800 meters thick ice.

Freezing three feet is not a day's cold, so Liu Pan understands it.

Drilling into the cave left by the predecessors, Liu Pan and the three of them felt relaxed. In order to save trouble, the passage carved out by the three of them was extremely narrow and boring, and could only be passed through. Although the cave left by the predecessors is still narrow, it is much better than the passage they made out without care.

The cave is still cold, but it is much drier than the outside world, and without an endless stream of moisture, it is impossible for the cave to freeze, so it has survived to this day.

Entering the cave, there was almost no rest, and the group of three walked forward, heading straight for the depths of the cave.

In fact, when they first entered the cave, the group of three had already noticed that there was a faint light from the depths of the cave. Although it was daytime at the moment, it was located in the depths of this ice-like mountain, and its light obviously would not be refracted from the cold ice directly above.

Therefore, there was only one possible light for this light, and that was the sky in the depths of the cave, which was the purpose of their trip.

Liu Pan couldn't hold back his heart at the moment. As for the barriers to the world, Liu Pan has looked through the ancient historical books related to them more than once, he is really curious, and at the same time, he also wants to know, is some possibility really possible?

Aside from Liu Pan, Ye Qing and Li Song were extremely excited.

For the heavens of the Tianfeng Continent, the description of the text in the ancient historical books is ethereal and inaccurate, and there are even many speculations and rumors about the gods. How can people not be excited that there is only a "wall" between us and God's world now?

Along the way, you can see that there are various traces of knives and axes on the four walls of the cave, and even the road surface under your feet is uneven. Obviously, the predecessors did not have the leisure to make this cave smooth and beautiful, and everything was mainly practical.

As the cave progressed, the light from the depths became more and more apparent. Liu Pan and the others noticed that they were not the first latecomers to use the caves of their predecessors to explore the depths.

On the walls of the cave around the cave, you can see different carvings every tens of meters, and at the end of each section there is a "step" to connect to the cave. Obviously, this is the best proof of what waves of people have passed so far.

All the way deeper, finally, the light in front of them was abnormally bright, and after a slight angle deflection, the three of them had no obstruction to glimpse the sky in the depths of the cave......

The last "staircase" is 7,800 meters away, and although the four walls of the cave are full of chisel marks, it is still clear that they are from the same person.

And this means that there was only one person who was the first to dig out this extremely cold and ice cave, and he alone carved out this distance of more than 7,800 meters.

It was only for a moment, and Liu Pan's hearts sank slightly.

The distance of the cave is 7,800 meters, and if any one of them comes to dig here, even if they use the most labor-saving method, they will definitely lose half their lives, and they have no guarantee that they will be able to leave alive.

However, although they were depressed, the three of them quickly adjusted their mentality, after all, this was not the beginning.

None of the three are ignorant. After reading the ancient historical books, you can understand that the Tianfeng Continent has decayed much compared to the beginning. Whether it is in terms of cultivation resources or the monks themselves, they are really two completely different eras.

Cultivation resources aside, the thunder tribulation that cultivators experienced when they broke through in their cultivation alone already explained a lot of problems.

In ancient historical books, the thunder tribulation that monks experienced from the beginning of their cultivation to the time they broke through the void and became a god was not the seven times in the current era, but the ultimate nine! Moreover, the thunder tribulation that finally broke through the void and became a god was not the current Seventy-Nine Divine Thunder Tribulation, but the Ninety-Nine Heavenly Tribulation that only exists in legends today!

Even the number of thunder tribulations was two less than at the beginning, so how could the monks of this age be compared to those who had experienced the entire thunder tribulation at the beginning?

It's not on a grade at all!

And it's great to be able to figure out a lot of things, at least, it won't become a demon in the heart of cultivation......

Moving all the way, although they were amazed by the strength of those monks back then, soon Liu Pan and his party returned to the sky that they could see at a glance in front of them.

Blue as the sea, is this really the sky that can be seen outside the mountain?

Liu Pan has a strange emotion, and he doesn't know how to describe this feeling, because in his subconscious, the end of the earth is just an adjective, and it is an impossible place to reach, and it does not exist at all.

However, now, he has reached the end of heaven and earth, visible to the naked eye, there is no sea and land in front of him, and as long as he stretches out his hand, he can touch the sky......

Is this a dream? Liu Pan wanted to ask himself this, but he didn't, because he knew very well that it was not a dream, because innocence was already close at hand.

At the end of the cave was an open space, and when Liu Pan and the three of them stepped on it, they were shocked.

From the cave ** to observe, it is the frog at the bottom of the well, the perspective of the leopard in the tube, when they really arrived at the edge of the sky, Liu Pan and the three finally realized that what they originally thought was really too small.

It is not worth talking about the foothold at the foot of the foot, which is only the size of half a football field and not smooth and smooth, but it is really worth noting the "face" of the sky!

Raising your eyes, following the wall of the sky (or the barrier of the world?), patches of solid ice were dug up, and the blue sky was close in front of you. And because the ice under your feet is directly against the wall of the sky, the whole thing looks like a huge irregular oversized window is installed in a huge iceberg!

After stopping and staring in silence for a long time, Liu Pan and his party didn't know how to continue to act for a while. The shock given by the wall of heaven is unprecedented and incisive at this moment!

I don't know how long it took, the three of them came back to their senses one after another and began to look around.

Thinking about it realistically, it is not difficult to understand that the solid ice clinging to the wall of the sky has been dug up in a large area. After all, the first person who came here dug up part of the ice and saw the sky, but the later people who came here in order to see more heaven were bound to expand on the basis of the first person digging up, and after that, more people came here one after another, in order to see more heaven, they would also expand further on the original basis. Over time, the wall of heaven that was exposed to the outside had the scale it has today.

Liu Pan raised his eyes and looked around, and the different chisel marks on the ice wall also clearly showed that the emptiness here was not the work of the same person.

After a general look around, although there were many noteworthy places, Liu Pan finally retracted his mind and focused his attention on the front wall of the sky.

The Wall of Heaven, the Barrier of the World, and the various information materials related to it in his mind quickly flipped through, Liu Pan took a deep breath, and then raised his feet and stood in front of the Wall of Heaven.

stretched out his hand, or hesitated, but in the end, Liu Pan's palm still fell firmly on the wall of the sky.

It is tough to the touch, perhaps because of its location, and the temperature of the wall of heaven is as cold as the ice around it.

Liu Pan didn't withdraw his palm, and in just an instant, the little water vapor in his hand turned into frost and condensed on the wall of the sky. Then, visible to the naked eye, Liu Pan's palm began to dry and blacken, and in a very short period of time, it turned into a terrifying zombie claw.

Completely zombified!

At this moment, Liu Pan indulged all the corpse spirit power in his body without any scruples, and the terrifying aura was pervasive, and even the extreme cold of this place could not completely suppress the yin evil that permeated around him. Even, at the place where Liu Pan's palm fell, that day seemed to be covered with a layer of dead gray because of this yin and evil.

Liu Pan stood in two positions not far away, and Ye Qing and Li Song's eyelids jumped wildly, and they didn't even dare to come out.

Regarding Liu Pan's actions, although Ye Qing and Li Song were checking the situation of the wall of heaven before, they also divided part of their perceptions and always paid attention to Liu Pan's actions.

After all, it was Liu Pan's suggestion to come here, and the ultimate purpose of Liu Pan's trip was precisely for this, and it was really difficult for Ye Qing and Li Song not to care about the purpose expressed by a Skywalker.

However, God knows that Liu Pan will completely zombie himself when he faces this wall of heaven!

What is he going to do?

The heart was shocked, and even the two of them could clearly feel the strong breath of death from Liu Pan. However, at this moment, Ye Qing and Li Song uncharacteristically did not show the slightest cowardice in their subjective consciousness, on the contrary, they unconsciously widened their eyes and stared at Liu Pan.

The power of the corpse swept wildly in his body, Liu Pan was silent, and after finally feeling that his zombification had reached the extreme, his eyes closed, and then he poked out his own perception.
