"Are you so sure? Why?" Black Demon asked curiously when White Demon said so categorically.

"There is no reason, I just feel that this world must have edges. Even if there are no edges, maybe it is round like our human world.

Maybe we will go full circle and return to our original place!" Bai Mo said.

"Back to the original place? What do you mean, if we keep going like this, we will eventually return to where we were at the beginning?" Black Devil frowned.

"It's hard to say. I don't know if the world is round, but I can't rule out the possibility." Bai Mo shook his head and said.

"If that's the case, shouldn't we first make a mark at this place? What if we have made such a big circle and have actually returned to our original position?" Black Devil said.

"Even if it is possible for us to go around in a circle and return to our original position, do you think this river will also be a circle?" Bai Mo said angrily.

"Why not? Didn't you yourself say that it is possible that this world is round? If it is round, it is not impossible that the river has circled back." Black Devil said.

"The water flows downwards, and we are walking upstream now, which means that the terrain we have been walking on for so long is getting higher and higher.

Otherwise, how could the water flow downwards?

If according to what you said, the river is also round, when we return to our original position one day, will we be in the upstream or downstream?

If we regard the place where we started as .asxs., then before returning to .asxs., we think that the place ahead should be the highest place, but after returning to .asxs., this place will become the lowest place again.

Already?

Do you think such a situation will happen?" Bai Mo said with a look of contempt.

This look made Bai Mo look like an idiot.

Maybe this world is indeed round like the human world, and they can return to the origin in the same direction, but it doesn't mean that water can also go around in a circle. So how is this possible?

"Master, do you think this is possible?" Black Demon ignored White Demon and asked Cheng Yu.

"Based on the situation in our human world, this situation is indeed impossible to happen.

But if there is some special power in this world, maybe it can be done." Cheng Yu thought for a while and felt that the black devil's idea was indeed a bit outrageous.

But if we don't look at the world from the perspective of the human world, it doesn't seem impossible.

However, this possibility should be extremely low.

"You see, even the young master thinks it is possible. Doesn't this world give us too many surprises?

Don't forget that when we were in the dark world below, didn't the young master say that we would follow the river and eventually return to the starting point?" Black Devil said.

"This world is indeed a bit weird, but don't forget that the environment in that dark world is changing all the time.

The reason why the young master felt that he was back in .asxs. was just because the change of environment allowed the young master to see the scenes that had happened before.

This scene may be an illusion. In fact, the young master has not returned to the original point at all, and the terrain is always changing." Bai Mo explained.

"Even if it is just an illusion, will we have the same illusion here? In the end, it will bring us back to the starting point?"

"At least we haven't noticed that the surrounding environment is changing now, so this situation is basically impossible."

"Anyway, I don't think so. We have been flying for more than four months. Whether this world has an end, or whether it has returned to... asxs, we will find out after trying it." Black Demon said unconvinced.

.

"From the current point of view, we should not have returned to the starting point, because I have always drawn maps of this world, and the current terrain does not seem to be repeated.

But we really should make a mark, which will also help us observe later.

If it really comes back, at least we still have a mark." Cheng Yu thought for a while and said.

He didn't know how big the world was. Although the arguments between the black and white demons seemed reasonable, there was definitely only one answer.

It's hard for him to say now who is right and who is wrong.

But Black Devil is right when he says that the world itself is very mysterious and very special.

When I was in that dark world, the surrounding environment was constantly changing.

After he came to this world, he really didn't notice that the environment was changing.

But is there a possibility that the environment of this world is also constantly changing, but they have not encountered the same scenes currently?

Moreover, some thinking logic in the human world may not be applicable in this world.

He once went to school in the secular world, and water flows to lower places because of gravity.

But under the interference of strong force, will the water flow to higher places? Of course it is possible.

If the world is also round, under some mysterious power, it can indeed achieve circular flow.

It's just that this kind of power is too powerful, and the world is so big, this kind of power is really unimaginable.

So he felt that they should really make a mark first. Many things that you think are impossible are only due to the influence of your own cognition.

When something impossible happens, your self-perception will be broken, and you will naturally believe that it is possible.

So now he doesn't think whether the Black Devil's statement is wrong.

Whether he is wrong or not, when they find the source of the river, they will naturally know whether his statement is right or wrong.

I saw a huge arrow mark left on a large stone wall by the river, recording the direction of the water flow.

This mark is eye-catching enough that if they return to this place again, they can see it at a glance.

Not only that, Cheng Yu also marked this arrow symbol here on his hand-drawn map, which means that they marked this location on the map.

After doing all this, Cheng Yu took the two of them and flew forward again.

"If I had thought of this earlier, I would have made a mark before we set off. Otherwise, we might have to come back here to find out whether we have gone in a circle.

But it will take more than four months to get from asxs to this position." Black Demon said with some regret.

Because there are too many similarities along the way, if there were no marks, they might not find themselves back in .asxs..
