The reason why Cheng Yu was unwilling to return to the territory of the Saints immediately was not only because he was using the sacred tree in the wrong direction, but also because he had released the sacred tree in the ground world before, but there was no response, which had a lot to do with it.

.

Although the environment on the ground and the world in the sky are different, he always believes that this is still the same world.

Since it is the same world, if the sacred tree is really connected to it, then it should also be able to sense it in the ground world.

But he didn't notice this feeling, so he felt that his idea might be wrong. He didn't want to waste two months returning to the territory of the Saint Clan.

We can only go back there and try to release the sacred tree when we can't find the exit here. No matter whether we succeed or not, it cannot be regarded as a waste of time. This is only reasonable.

As Cheng Yu continues to explore, the information on Cheng Yu's hand-drawn map becomes more and more abundant.

Although currently, there is only one roughly straight line of map information on the map.

But Cheng Yu knew very well that as long as he didn't find the exit for a day, he would continue to explore, and by then there would naturally be more than one straight line of map information.

There will definitely be countless horizontal, vertical, or even diagonal lines, etc. All the information from all directions will be gathered together, and finally a rough global map of this place can be formed.

Although it seems useless, it can mark the places Cheng Yu has walked, so at least he will not repeat these places next time.

Therefore, the significance of this hand-drawn map is still very important.

But if the entire map of the entire territory in this final picture is roughly drawn, but the exit is still not found, he can basically give up on this place.

However, Cheng Yu spent the next two months. Although he discovered a lot of human ruins, they were only small towns, and he never encountered even a decent big city.

This made Cheng Yu a little disappointed.

"Is my guess wrong? No one here builds a big city?" Cheng Yu said speechlessly as he looked at another small town in front of him.

This is already the twenty-fifth town they discovered after entering the fairyland.

So many small towns were marked as dense dots on his map, but not a decent big city appeared.

Of course, if there is no big city, it doesn't matter as long as he can find some useful clues in these small towns.

After all, they are not here to find Dacheng. They just want to find more information about this place, including the exit information.

However, none of these small towns left any useful clues. The altars in some small towns were relatively well preserved, but they only left similar textual contents.

In some towns, even the altars have not been preserved, let alone the simplest writings.

"We have already looked for so many small towns. Maybe there are not many people in this world, so there are no big cities at all, and there is no central and prosperous place.

Maybe if you keep looking like this, there will only be a small town like this in the end." Zhenhun had actually wanted to say this for a long time, but he was afraid that Cheng Yu would think he was urging him to go back there to do experiments with the sacred tree.

According to Cheng Yu's idea, if you go deep into one camp at the border of the two camps, you will definitely find their big city.

But the reality did not appear according to Cheng Yu's idea. After so long, they encountered more than 20 small towns, but there was not a decent big city, which had to make them think like this.

"It would be great if I could find the boundary of this place now, but I don't even know where the boundary is. This is really troublesome and a waste of time!" Cheng Yu looked up at the high energy above his head.

cover.

He didn't feel that the energy shield was any closer to him.

Logically speaking, if he keeps walking in one direction, this energy shield will always have a limit.

As long as there is a boundary, the energy shield cannot always be at such a high position.

But it has been several months, and this energy shield has not become shorter at all. Isn't this place too big?

"There really isn't a continent in this world, right? So the energy shield above your head covers the entire world?" Cheng Yu said.

"Isn't this possible? Is it possible that these continents are already above us, but there is still water underneath the continents, so this energy shield has always existed in the entire world?" Zhenhun said.

"This is impossible! The mainland does not float on the sea, so it is impossible for the mainland to float above our heads!" Cheng Yu shook his head and said.

He is a modern young man who has studied geography, and the continents of the earth do not float on the sea.

So if this is the earth, then the energy shield under this sea area must have an edge, because there will be continents blocking these seas.

According to this structure, the world should also be like this.

But now he has not discovered the boundary of the energy shield at all, which gives him the feeling that there is no continent in this world.

A world with only seas and no continents does not exist.

Just like the world on the ground before, he didn't find the sea. Although there were rivers, they were basically all soil, rocks, and sand.

The world above is the opposite, with only water and a few islands. This is not impossible.

But if that's the case, the world is already huge, so wouldn't he be unable to find the boundary at all?

"Didn't you say that the human world is a ball? Then is this world the same? Since you can go in circles in the human world, can you also make gray circles in this world?" Zhenhun thought for a while and said.

"You mean if you keep walking in one direction, you will eventually come back here?" Cheng Yu said.

"Absolutely. If this energy shield has no edges, then you should be able to walk back.

But if there is an edge, then you will definitely encounter an edge, and you won’t be able to walk back!

Is that true?" Zhenhun said.

"That's true, but this world is obviously much bigger than the human world, and I've been flying in the same direction for so long.

You know, in the human world, I don’t even know how many times I’ve gone around.

So I want to go around this world, how long will it take? I might not be able to go around in a few years, so what should I do?" Cheng Yu thought for a while and said.

If it were just a small world like the human world, then this method would naturally be feasible, and he would have already completed this circle.
