Chapter 3139

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

"This place is really dangerous. I think if we find treasure here, we'd better leave this place as soon as possible." He got Cheng Yu's affirmation, and his heart was relieved.

After all, Cheng Yu said that the monster was more terrible than the giant rock wolf.

If they are not restricted, they will die if they meet them!

"Although the exotic animal we met before is indeed limited, it does not mean that all the exotic animals will be limited.

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

Therefore, we had better not take chances. If we really meet those monsters, I'll let you escape, you'll try your best to escape, don't have any hesitation! " Cheng Yu said seriously.

"Well, we know!" The crowd nodded.

Seeing that Cheng Yu was so serious, they naturally understood the danger and could not make fun of his own life.

Moreover, once someone has a problem, others may also be dragged down. If one of them is trapped, can others run? Naturally, we need to find a way to save people.

Therefore, if they really meet this kind of strange beast that Cheng Yu said, they should run away quickly and don't give other people any trouble.

Cheng Yu told you so, he also believed that you should keep it in mind. If you really want to meet a strange animal, you will definitely do as he said.

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

After all, who else will help them break the ban when they are trapped?

"This passage is so long. Are we really heading for one of the towers?" We have been walking in this passage for a while, but we haven't reached the end yet, or we have found something. Everyone is a little strange.

"Don't worry. The passage is really strange. Its direction seems to be changing all the time, but I find that it is changing in one direction. That is to say, we may return to the original direction after a turn! " Chen Hongyuan is most concerned about the direction of this channel.

Therefore, he has been paying attention to this direction. Once the direction is changing, he will make an estimate in his mind.

However, because he could not see the complete appearance of the passage, and could not have a mark like the outside. So he can only estimate roughly in his mind.

Nevertheless, he felt that his estimate was very close.

After they enter this passage, they are constantly turning to the right, but the trend of this change is relatively slow and hard to feel.

However, after continuous turning to the right, they finally turn back to the original direction, so they may now return to the original direction when they entered the passage.

"Is that so?" Asked Xinluo.

"I think even if we are not in the first direction, we are not far away." Chen Hongyuan said.

"If so, does it mean that we are not heading for one of the five towers?" Said Xinhai.

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

"That's great. It shows that our choice is right. There are no terrifying beasts in this passage. It may be a treasure!" Heart sea excited said.

In fact, as long as they didn't go to those monsters, he felt very lucky.

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

Now that they're back in the original direction, it's a lot easier. Moreover, the chance of treasure here is greatly improved.

"Don't be happy too early, even if we are still moving in the direction of the beginning, it doesn't mean that we are still on the original line. If the radius of our circle is constantly changing, then we are out of the original position.

Even if we are still moving in the original direction, we are still changing the direction! " But Cheng Yu threw a basin of cold water on everyone.

In fact, this is a very simple geometric model. If the radius remains unchanged when they turn, they will return to the original place after turning for a week. When they go back to the original direction, naturally everything will remain unchanged.

But if the radius is constantly changing when turning, you will not be in the original position after a turn.

In this way, from the beginning of the entrance, their direction has completely changed.

"Younger martial brother Yu, what do you mean by this radius?" For Cheng Yu's too modern vocabulary, people are confused.

"It's a very simple metaphor. I'll just draw a picture for you." Cheng Yu didn't have the time to explain to them what radius was not. Instead, he found a stone and drew a simple figure on the ground.After drawing these two different possibilities and comparing their positions at the beginning of entering the passageway, people can clearly see what Cheng Yu wants to express.

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

If it's true, as Cheng Yu said, when they change direction, the radius is also changing. Now even if they are the same as the original direction, they are at most in two parallel lines, which are not in the same line as the original.

Compared with the origin, their direction has changed.

"Yes, if it's really like what I think, no matter how the radius of our turn changes, but after this turn, our current direction is probably to point to the wooden tower or the water tower, or between them!" Cheng Yu marked the direction of the tower on the water city, and then speculated.

"Brother Hongyuan, what do you think? Do you think we are in the same position now or have we changed our position? " Heart river a face serious looking at Chen Hongyuan said.

"I didn't think so much about it. I can only estimate that we are still moving in the original direction, but I'm not sure what kind of situation Cheng brothers said Chen Hongyuan shook his head and said.

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

So after being drawn two pictures intuitively by Cheng Yu, he felt that what he had considered before was too simple. He didn't consider this possibility!
