"Master, look, is this the river?"

Three days later, Black Demon suddenly saw a winding place in front of him that looked like a river, and he suddenly became extremely excited.

"I guess so. Judging from the time and location, we should have reached our destination." Cheng Yu looked at it and became nervous.

Although finding the river does not mean that he has found the exit, the appearance of the river has given him at least half hope.

Their speed became faster, and before long, a river actually appeared in front of them.

"Sure enough, this is it. I believe we will find the exit soon." Black Devil said impatiently.

"But where should we look next? Upstream or downstream?" Bai Mo asked.

In fact, he had been thinking about this issue along the way, but he never had a better answer.

Now that they have reached their destination, no matter whether they have a better way, they must make a decision.

"What's so confusing about this? Just choose a direction first. If you find the wrong one, you'll just have to come back later." The Black Devil didn't care at all.

Anyway, there is only one river. If you can't find it at this end, just look for it at the other end.

"You made it simple. Do you know how long this river is?" Bai Mo asked.

"I've never been to this place before, how could I know how long this river is!" Black Devil said angrily.

"It's okay, you don't even know how long this river is, what if the distance of this river is longer than the distance we walked along this way.

Under normal circumstances, we probably won’t know whether we made the mistake until we get to the end.

So think about it, if we choose the wrong direction from the beginning, how much time will be wasted if we go back?" Bai Mo said.

"Then do you have any good way to prevent us from looking in the wrong direction?" Black Devil said.

"No!" Bai Mo said firmly.

"You would still be so arrogant without you!" Black Demon was almost frightened by White Demon. This guy had no choice but to be so confident. I have never seen such a shameless person.

"I'm just telling you this fact now. If you make the wrong choice, we may still miss the exit.

So I think we should choose carefully instead of just choosing a direction casually.

Master, what do you think?" Bai Mo said.

"Of course what you said is right, but based on the information we have now, we have no way to determine which end is correct." Cheng Yu took out the copied stone paintings and said.

"It's just that it's impossible to tell from this painting which end we should go to.

For example, the river in this painting, do you think it flows downward or upward?

And even if we can determine which end the river in this painting flows to, we cannot determine the environment on both sides of the river.

So no matter where you stand, you can see the angle of the river flowing upward.

You want to know which end is right, this is simply impossible." Black Demon immediately retorted again.

"Alas!" Bai Mo also sighed directly. How could he not know this truth?

It's just that he doesn't want everyone to choose the wrong direction at the beginning, so that they may not be able to find the exit in a short time.

"You guys think, if one day the same sky happens on both days, do you think we can see the exit directly?" Black Demon stared closely at the vortex in the painting in his hand.

I saw a circle above and below the vortex, which made the vortex look like it was sandwiched between two suns. Does this mean that this vortex will also appear in the sky?

If you can even see the sun, can you also see this vortex?

"I'm afraid this is unlikely. No matter how far the distance we can see is, it will eventually have an end.

Just like this river, we cannot see its end at a glance.

The same is naturally true for this exit. If we are lucky and this exit is very close to us, we will definitely be able to see it.

But our luck may not be so good or such a coincidence? I don’t think we can afford to gamble.

If we are far away, even if the exit appears, we will definitely not be able to see it." Bai Mo said.

"But if you look at this vortex, is it possible that it is like the sun, hanging high in the sky, and anyone can see it from anywhere?" the black devil continued.

"It's impossible for each of us to see the sun from anywhere, that's because the sun is too far away from us.

Moreover, the sun is not in the world we live in at all, just like we cannot reach the sun even if we fly into the sky.

If everyone in the world could see this exit when it appeared, it would be impossible for us to reach that place.

If you think that because the vortex in this painting is as high as the sun, the vortex is also the same as the sun, then you are wrong. This is just a visual problem.

Just like this stone, from our perspective we can see that this stone is right next to the sun!

But in fact, this stone is right in front of us.

People in other places can see the sun, but they can't see this stone." Halfway through, Cheng Yu picked up a stone on the ground, raised it above his head, and said to the sun.

"In this case, don't we have to rely on luck in the end? If we are lucky, then we have chosen the right direction.

But if you are unlucky, you will have to come back when the time comes.

As for whether the exit will be missed during this period, there seems to be no way to change it." Black Demon said helplessly.

"Master, then you make the decision. No matter whether you choose wrong or right, we will follow you anyway." Bai Mo finally looked at Cheng Yu and said.

The information they know now is indeed not enough to determine this direction.

Really everything just depends on luck.

If they're lucky, they might be able to find the exact location of the exit soon.

But if you are unlucky, you may really have to wait until you have found that end of the river before you can go back and find the other end.

How much time will be wasted in this way? Now they don't know how long the river is, so there is no way to be sure.

But it is precisely because of these uncertainties that Cheng Yu and the three of them are in trouble.

Of course there is nothing good to say if you choose the right one, but you are afraid of choosing the wrong one.

Of course, it doesn't matter if you just make the wrong choice, you can just go back and try again.
