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

"This place is really dangerous. I think if we find the treasure here, or leave this ghost place early!" With Cheng Yu's affirmation, Xinhai is also a lot of relief.

After all, Cheng Yu said that the stranger is even more terrifying than the giant stone wolf.

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

"Although the strange animal we encountered before was indeed subject to some restrictions, it does not mean that all the beasts will be restricted.

In addition, even if they are restricted, it does not mean that they are not threatening us. Just like us before, it is still not trapped by the prohibition.

Therefore, it is best for everyone not to be lucky. If we really meet those strange animals, I will let you escape and you will run hard, don't hesitate! Cheng Yu said seriously.

"Well, we know!" everyone nodded.

Seeing Cheng Yu so serious, they naturally understand the dangers of this, it is absolutely impossible to make fun of their own lives.

Moreover, once someone has a problem, others may be dragged down. Just say that if someone is trapped, can other people run? Naturally, we must find ways to save people.

Therefore, if they really meet the different animals that Cheng Yu said, then run quickly and don't bother others.

Cheng Yu confessed to everyone, he also believes that everyone should be in mind, really want to meet a different animal, will definitely do what he said.

What he is most worried about is that everyone is trapped together. If that is the case, then there is no way to save.

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

"This channel 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 have not reached the end, or found something, everyone has some Strange.

"Don't worry, the passage here is really strange. Its direction seems to have been changing, but I found that it changes direction in one direction. That is, we may turn around and then Going back to the original direction!" 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 has an estimate in his heart.

But because he can't see the complete appearance of the channel, he can't have a mark like the outside. So he can only estimate it in his heart.

Despite this, he also feels that his estimate is inseparable.

After they entered this passage, they continued to turn to the right, but the trend of this transition was slow and difficult to feel.

But after a constant turn to the right, but finally turned back to the original direction, so they may now return to the direction of the initial entry into the channel.

"Is that the case?" Xin Luo asked.

"I feel that even if our current direction is not the initial direction, but it is not far behind." Chen Hongyuan said.

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

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

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

In fact, as long as they are not going to those beasts, he feels very lucky.

Just because the direction of the passage was changed, he felt that the atmosphere was particularly depressed.

Now that they are back in the very beginning, everything is more reassuring. Moreover, the opportunity to hide treasures here has greatly improved.

"Don't be happy too early, even if we are still moving in the direction of the first entry, but this means that we are still on the original line. If the radius of our circle is constantly changing, then we have already left the original The location is gone.

Even if we are still in the original direction, then we are still changing the direction! "Cheng Yu is pouring a cold water for everyone."

This is actually a very simple geometric model. If they turn around, the radius will remain the same. After a week of turning, they actually go back to the original place. At this time, they go in the same direction. Naturally everything. It is unchanged.

But if the radius is constantly changing when you turn, then after you make a turn, it is already not the original position.

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

"Yu Shidi, what do you mean by this radius?" For the vocabulary that is too modern, everyone is confused.

"This is a very simple metaphor. I will know if you draw a picture for you!" Cheng Yu did not have the time to explain to them what radius is not radius, but to find a stone directly, and then draw a simple on the ground. Graphics.

Draw these two different possibilities, and then compare the position and contrast when they first entered the channel, everyone will clearly see what Cheng Yu wants to express.

"So, although we are still in the same direction, but the position has already changed?" Xinhai looked at two simple geometric figures on the ground, and the two possibilities were completely different, which shocked them.

If Cheng Yu said that when they change direction, the radius is also changing. Then they are just like the original direction. They are at most two parallel lines ~www.readwn.com~ not the same as before. On a straight line.

This is in line with the original point, and their direction has changed.

"Yes, if it's really like I thought, no matter how the radius of our circle changes, but after this turn, our current direction is probably pointing to the wooden property tower or the water property tower, or just here. Between!" Cheng Yu labeled the direction of the tower on the water city, and then speculated.

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

"I didn't think so much. I can only estimate that we are still in the original direction, but in the end it is the case that Cheng Brothers said, I am not sure!" Chen Hongyuan shook his head and said.

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

So after Cheng Yu had drawn two pictures so intuitively, he felt that he had considered it too simple before, and he did not consider this possibility!
