"It should be like this!" Cheng Yu nodded and said.

"This place is really dangerous. I think if we find a treasure here, we should leave this ghostly place as soon as possible!" With Cheng Yu's affirmation, Xinhai was relieved a lot.

After all, Cheng Yu said that the strange beast was more terrifying than the boulder wolf.

If they are not restricted, then if they are encountered, it is a dead end!

"Although the strange beast we met before was indeed subject to some restrictions, it doesn't mean that all the strange beasts will be restricted.

In addition, even if they are restricted, it does not mean that they are no threat to us. Just like us before, we are still trapped by their prohibition.

Therefore, it is best not to take chances. If we really encounter those strange beasts, if I tell you to escape, you should run as hard as you can without any hesitation! "Cheng Yu said seriously.

"Well, we know!" Everyone nodded.

Seeing Cheng Yu being so serious, they naturally understood the danger, and it was absolutely impossible for them to joke about their own lives.

Moreover, if someone goes wrong, others may also be dragged down. Just say that if one of them is trapped, can the others run? Naturally, it is necessary to find a way to rescue people.

Therefore, if they really encounter the strange beast Cheng Yu mentioned, they should run away quickly and don't cause trouble for others.

Cheng Yu told everyone this, and he also believed that everyone should keep it in their hearts. If they really encountered a strange beast, they would definitely do what he said.

What he was most worried about was that everyone would be trapped together. If that was the case, there would really be no way to ask for help.

After all, who else will help them unblock them when they are trapped?

"This passage is so long, are we really going in the direction of one of the towers?" Everyone walked in this passage for a while, but they still haven't reached the end, or found something, everyone is a little bit confused. Strange.

"Don't worry, the passage inside is really strange. Its direction seems to be changing all the time, but I found that it is in the same direction. Back to the original direction!" Chen Hongyuan is most concerned about the direction of this passage.

Therefore, he has been paying attention to this direction, and once the direction changes, he will make some estimates in his heart.

But because he couldn't see the complete appearance of the passage, and couldn't have a mark like the outside. So he can only make a rough estimate in his heart.

Even so, he also felt that his estimate was absolutely accurate.

After they entered this channel, they kept turning to the right, but the trend of this change was relatively slow, making it hard to feel.

But after repeated turns to the right, they finally turned back to the original direction, so they may now return to the direction they originally entered the passage.

"Is that so?" Xin Luo asked.

"I think even if our current direction is not the original direction, it is not far away." Chen Hongyuan said.

"If this is the case, does that mean we are not heading towards one of the five towers?" Xinhai said.

"You can say that!" Chen Hongyuan nodded and said.

"That's great. It shows that our choice is right. There are no scary beasts in this passage, but it may be a treasure!" Xinhai said excitedly.

In fact, as long as they didn't go towards those strange beasts, he felt very lucky.

Just now because he discovered that the direction of this passage was changing, he felt that the atmosphere was particularly depressing.

Now that they have returned to the original direction, everything is much more at ease. Moreover, the chances of hiding treasures here will be greatly improved.

"Don't be too happy, even if we are still heading towards the original direction, it doesn't mean that we are still on the original route. If the radius of our circle is constantly changing, then we have deviated from the original route. location.

Even if we are still moving in the original direction, then we are still equivalent to changing the direction! "Cheng Yu poured cold water on everyone.

This is actually a very simple geometric model. If the radius remains the same when they make a turn, they will actually return to the original place after turning a circle, and then walk in the original direction at this time. is constant.

But if the radius is constantly changing when turning, then after you turn around, you are no longer in the original position.

In this way, looking at the entrance of the passage from the very beginning, their direction has completely changed.

"Junior Brother Yu, what do you mean by radius?" Everyone was a little confused by Cheng Yu's too modern vocabulary.

"This is a very simple metaphor. I'll draw it for you and you'll know!" Cheng Yu didn't have the time to explain to them what the radius is or not. Instead, he found a stone and drew a simple one on the ground. graphics.

After drawing these two different possibilities, and comparing their positions when they first entered the passage, everyone could clearly see what Cheng Yu wanted to express.

"So, although our direction is still the same now, but the position has already changed?" Xinhai looked at the two simple geometric diagrams on the ground, and the results of the two possibilities were completely different, which shocked them.

If it is true as Cheng Yu said, when they change direction, the radius also changes, then even if they are in the same direction as before, they are at most two parallel lines, not on the same straight line as before.

In this way, compared with the origin, their direction still changes.

"That's right, if it's really what I think, no matter how the radius of our circle changes, but after making a circle like this, our current direction is probably pointing to the wood attribute tower or the water attribute tower, or it's right here Between!" Cheng Yu marked the direction of the tower on the water city for everyone, and then speculated.

"Brother Hongyuan, what do you think? Do you think we are in the original position or have we changed?" Xinhe looked at Chen Hongyuan seriously and said.

"I didn't think about it so much. I can only guess that we are still moving in the original direction, but I'm not sure whether it belongs to what brother Cheng said!" Chen Hongyuan shook his head and said.

He has been calculating the change of direction, but never thought of the situation Cheng Yu said.

So after being so intuitively drawn by Cheng Yu, he felt that what he had considered before was too simple, and he didn't even consider this possibility!
