Chapter 3139 (2/2)

”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!
