After a short period of confusion, everyone didn't have Lin Bei's instinct for rational thinking, but were more affected by the excitement, and they all said with a happy face: "This is the flag of Huaguo!" Absolutely, yes, definitely! ”

Chu Yaxuan grabbed Murphy's hand tightly, and said with tears in his eyes: "Fei Fei, didn't you ever be a soldier before, does the flag here mean that this is our Huaguo's domain!" ”

"yes, I've heard that too." Song Huilin's equally excited voice trembled: "Where the national flag is planted, it means that the country's forces are protecting that place... Have we arrived in the territory of China this time? ”

Murphy wasn't sure, but he vaguely felt that it was a joy to see the flag here.

Just when everyone was excited, Du Zilin noticed that Lin Bei had been frowning and silent, and couldn't help but ask curiously, "Mr. Lin, what's wrong with you?" Do you think this flag has any special meaning? ”

Lin Bei nodded first, then shook his head again, still frowning: "To be honest, I'm not sure now, I think it's a bit strange that a flag suddenly appears here, but I can't say what's weird." ”

Du Zilin wanted to ask something, but Chen Nuolan gently pulled her arm, shook her head at her, and motioned for her not to ask again.

Although Du Zilin was curious, she also knew that Chen Nuolan and Lin Bei were teammates who had been working together since the last desert island, and they must know each other very well, so after biting her lip lightly, she didn't ask any more.

Chen Nuolan walked to Lin Bei's side and whispered: "Captain Lin, don't think about it so much, now that it's getting darker and darker, let's solve the problem of where to live at night first." ”

"Huh? Oh..."

Lin Bei glanced back at Chen Nuolan, nodded to show that he understood, and didn't say anything more.

In fact, just now, Lin Bei has been stuck in memories and remembered a lot of previous things. For example, on the previous desert island, they had seen traces left by suspected ancients, and on this island, they saw flags embroidered with stars.

In a trance, Lin Bei had a vague feeling in his heart, that is, they had not been completely separated from the city, and there had always been a kind of power in the underworld, which was pulling and hinting at them...

But what exactly is the answer? What should they do?

Fortunately, Chen Nuolan reminded him in time, it is not interesting to stare here and think about it now, it is more important to solve the problem first.

So Lin Bei turned back to everyone and said, "Since we have found the flag, we have to go over and see what the situation is." Be careful, take care of each other, and don't get separated. ”

Saying that, Lin Bei took the lead, walked in the front and led everyone in the direction of the flag.

However, after walking a few more steps, Du Zilin suddenly exclaimed, grabbed Lin Bei, and whispered: "Mr. Lin, wait a minute, look at the crocodile lying next to the flag over there!" ”

The terrain over there is relatively low, and the crocodile was lying in the pit just now, and I really can't find it if I don't look carefully. After being reminded, Lin Bei looked at it, suddenly stopped, made a stop movement, and hurriedly whispered: "Don't talk, everyone, be quiet!" ”

Seeing Lin Bei say this, everyone closed their mouths, and after carefully glancing ahead, they shrank back one after another.

Chu Yaxuan couldn't help but complain softly: "What's going on on this island, why are there so many crocodiles, it's so scary..."

There are indeed a lot of crocodiles on this island, but Lin Bei is thinking about another question now, that is, there are many crocodiles on this island, does it also show from another perspective that the ecological environment of this island is still good?

Because the crocodile is, to a certain extent, also a beast at the top of the food chain, just like a tiger and a lion, if you want to live for a long time, you must have a complete set of ecological chains to feed.

Take the marine ecosystem, for example, there is a mantra that says, big fish eat small fish, small fish eat shrimp, and shrimp eat pebbles. Of course, shrimp can't really go overboard by eating grains of sand, they eat something like big fish excrement, and then recycle nutrients from there.

However, in terms of volume, thousands of dried shrimp can fill the stomach of small fish, and thousands of small fish can make big fish enjoyable.

Scientists have done research that when a whale hunts, it opens its mouth the size of a small mountain peak and swallows tons of food in one go.

The same applies to the replacement of this marine system on land.

Things like cockroaches and bugs are so fertious that they feed rats, rabbits, and pheasants, and small animals like rabbits and mice become the favorite of foxes and wolves.

In this way, the whole ecosystem is formed.

So from this point of view, the fact that these crocodiles can now live in pairs on this island is enough to show that the food resources on this island are still very rich, otherwise it would not be possible to support this group of animals to reproduce and pass on from generation to generation.

Hey, but if you want to understand this, the top priority is to find a place first, so that your group of "outsiders" can settle down on the desert island first...

Lin Bei scratched the back of his head depressedly, raised his head and looked around for a while, and suddenly his eyes lit up, and he found a very spectacular rock group.

Just now, their attention was attracted by the red flag, and they didn't even notice that in front of them to the left, there was a large group of towering rocks.

And the rocks are naturally stacked on top of each other, as high as five storeys of buildings, standing there horizontally and vertically, like those characteristic buildings in the city.

Of course, the rock group is far more "spiritual" than those artificially built high-rise buildings, or it is said that nature is full of magical power, and the stones are naturally and fittingly combined.

And almost at the height of the three stories in the rock group, Lin Bei saw that there seemed to be a very flat place under an arched rock, so it should be enough for them to take a short rest first.

Lin Bei was about to beckon everyone to go to the location of the rock group as if he had discovered a new continent, but Shen Chao suddenly reminded: "Captain, be careful, you see that there are crocodiles over there!" ”

Damn, really, about twenty meters away on the way to the rocks, there was another crocodile lying still.

Lin Bei was two big heads in an instant, and he really wished that there were enough bullets in the gun to send all these annoying beasts to the western sky!
