The two of them talked a little, which made the slightly dull atmosphere a lot easier, but the heart "fluttered", laughed out loud, and joked: "The voice of the great shore, the great footprint, I see the most fat figure, huge footprint!" I agree with the guess that you are the camel into a fine change! ”

When Yunya Nuan buried the bear fat man, this guy blew his beard and stared, looking angry. But when he was heartbroken, this guy put on a hippie smile, which seemed to be very useful, and he muttered with a smile:

"Master Xiong, I don't want you, why don't you say that we are not angry, we can support the boat in our stomachs, and there are a lot of adults!" It's hard to say whether you can hold the boat or not, but it's true that the amount of food is large.

Kaf and Ada haven't made a choice yet, and seem to be still thinking about it. On the deck, Kexin drew an open circle with water, slightly higher at the bottom, and said:

"We're right where the bottom meets the side, if the guess is correct!" Ke Xin stated that this was just her guess.

Then he continued: "Then the side is divided into two regions, temperate and tropical, right?"

Everyone nodded, it is true, when they started to enter the island, they didn't see those island plants, they were all towering trees, which was very unreasonable, but after passing by, the terrain came down, but they came to this position, which made people have to marvel.

Kexin saw that everyone nodded, and then continued:

"Since entering the island, we have experienced two full moons, that is to say, we have walked for more than a month, take the whole number, to say more, even if we have walked for forty days, according to our speed, we will walk forty or fifty kilometers a day, and the same maximum value, according to the calculation of fifty kilometers, we have walked two thousand kilometers."

Speaking of this, she paused for a moment, took a sip of water, and looked at everyone's shocked expressions, not knowing when she didn't calculate, after this calculation, they had already traveled such a long way, so the huge island was simply terrifying.

Ke Xin moistened his throat and said:

"However, we have never walked in a straight line, this route is only a curved distance, and the actual length will never exceed a thousand kilometers, in the rainforest, we almost walk in the shape of a triangular ruler, most of the distance into the island, is also followed by the river with nine turns and eighteen bends, so the number of this thousand, only more and not less."

Yunya Nuan and Pete are all people who have marched, and they know that the straight-line distance and the actual distance, in the mountains, can sometimes differ several times, only reduced by half, this is a very conservative algorithm, and they have traveled all the way, the distance they travel every day, on average, is definitely not 50 kilometers, and they have not walked for forty days.

If you count all these words, then in fact, the straight-line distance, these people will walk between 500 and 700 kilometers.

The bear fat man nodded, grinned and said: "But the little beauty is smart, once you finish the calculation, it seems that there is nothing to be afraid of in this desert!" It's just a matter of a few hundred kilometers, hurry up and go out in a few days! ”

Ke Xin nodded and continued: "Yes, the straight-line distance is really not much, but Xiong Xiaoxiao said that it would be a bit exaggerated to go out in a few days, I calculated, how can it take ten days!"

The fat man was said by Kexin, his big face trembled, and he opened his mouth wide and was about to say something, but he was grabbed by Yun Yanuan and pressed it on the back of his hand, not letting him say it, no one paid attention to these small movements.

At this time, Se Ami asked: "Even if we are all conservative calculations, without a thousand kilometers, it is not ten days to get out?" Her words naturally negated what Kexin said.

But Xin shook his head with a smile and said:

"The bend at this junction is the location of this lake, and if we continue to move forward, the terrain will be higher and higher, even as when we enter and exit the island, or even higher, and the gravel will accumulate from top to bottom, and when we reach the lake, it will be completely blocked, so that the desert area should occupy about half of the rest of the distance, that is, if it is a thousand kilometers, this desert will also account for five hundred."

A few people understood the meaning of Kexin, the first halfway, divided into two environments, then the future road, will also be like this, then ten days out of the desert is not impossible, because in the desert, with a compass, it is completely possible to walk in a straight line, without bending.

Ida looked at the picture drawn by Kexin, tilted her head and asked in non-fluent Chinese, "But, this is obviously the bottom, how can the terrain get higher and higher?" Isn't it supposed to be lower and lower? ”

This is also a question from other people, Kexin nodded, added a few strokes to the bun-shaped pattern on the ground, and said: "You see, this elongated noodle is what we see inside, and as for the bun-shaped, it is seen by people outside the space."

Just like the cosmic space in which our earth is located is obviously round, but our observation is funnel-shaped, this is because of the angle of our observation, the earth is round, but we stand on it and it looks flat, this is because we are inside.

The reason why I concluded that this is the lowest point of the island is not because of my confidence in the spatial model I guessed, but because of common sense! ”

Ida hurriedly asked, "What common sense?"

Kexin pointed to the river in the distance, and everyone looked at it, and it suddenly became clear. I have to admit that Kexin's observation of the surrounding environment is incomparable to others.

Yes, it's really just common sense, the water flows down, and the small river doesn't flow out of the lake, but flows in from the desert, and the water from the front and back and left and right all gather here to form a lake, so at least it proves that this place is much lower than the desert.

Her guess undoubtedly gave everyone a lot of confidence, if it was only a ten-day journey, then they should be able to resist the past when they set off, even Pete was moved, but it was only a moment, the courage he had just mustered seemed to be vented again, I really don't know, what kind of terrifying experience the desert has brought him.

However, everyone also knew that this was just a hearty guess, and no one dared to say whether the truth was so, Cafu shook her head, slowly walked behind Pete, and chose to stay.

Ida hesitated for a moment, then walked over to Kaf's side.

A few people choose to continue to run through, maybe this can be called brave, or they can be called fools, but they know that they have to do it, because there are many reasons, the lights and wine, the fancy world, or relatives, or others, in short, they have a reason to go back, which in their eyes is much more important than life.

Pete, Carf and Ada's choice cannot be called cowardice, they judge the situation and know the most reasonable choice, whether it is bright or green, relatives and friends, they always have to live to have a chance, they do not give up and go back, but choose to wait.

Yun Yanuan nodded, this meal seems to be a casual meal, Pete and the three of them will inevitably have some sadness on their faces, or other emotional colors, but Yun Yanuan knows that Kafu definitely has no sadness for herself, this stingy woman has hated herself for so long because of a slap.

What he didn't understand was why Carf hated him so much, perhaps only she knew. Maybe it's because she can't afford to save her life, since she can't afford it, and if she wants to feel good, then she has to hate, which is a very strange way of thinking, but there are indeed many such people. Of course, it may just be because he slapped her. But he doesn't waste his mind on it, because some people are not important, so things about this person are also not important.

However, it was obvious that Yun Ya Nuan and the fat man had a happy face, and even smiled a little badly, making people feel that these two people seemed to be thieves who stole their wallets and shared the spoils.

Yun Yanuan cleared his throat and said, "What, Fat Bear, go ahead and get out the fruits of our labor yesterday, just seven of us, it should be more spacious!"

The bear fat man was even happier than Yunya, and it seemed that he couldn't wait for a long time, so he ran out with a stinger, and it was a miracle that more than 200 catties could run like a monkey.

After a while, a roar came out, this sound could not be more familiar, but it had not been heard for a long time, but these people still recognized it at once, it was the sound of the engine.

What engine? Everyone was puzzled, but soon, they knew what it was, because a big and majestic guy sailed out on the third deck......
