It can be said that three things are necessary for the living environment of wood frogs:

First, before the catastrophe, some people found traces of forest frogs from 800 to 4,300 meters above sea level. This area may be classified as the daily activity range of forest frogs. They can eat small bugs, nibble leaves and wild fruits when they are thirsty.

Can drink some pure dew from high altitude. Summit 23S.

Fastest update

Second, temperature. Wood frogs are not tolerant of high temperatures. On the other hand, they prefer to move in cold places. Of course, freezing below zero will definitely not work and these little guys will be forced to hibernate.

Third, there must be a clean water source at the bottom of the mountain that is suitable for breeding offspring to ensure that the tadpoles can eat, drink, play, and grow up safely and healthily. The best water source for this water source is the melted ice and snow water on the top of the mountain: there are no established natural enemies in it and the temperature is low, so it is not suitable for most fish.

Survive.

Well, all in all, Rana has the tone of an outsider, and his personality is quite high.

He looked up at the bare gray-brown mountains and sighed.

He could clearly see at a glance that the big rock at the top of the mountain had been corroded horizontally by the sea wind and had many "bug eyes" on the surface. He knew without thinking that there must be no rain in this place.

Even though we are here, we still have to climb to the top of the mountain to take a look. Maybe there will be a different situation on the other side of the island.

Although the bare mountain peak in the center of the island does not look very tall, Lin Chou intuitively told Lin Chou that this hilltop looks very thin. It must be one or two thousand meters high. The slope at the foot of the mountain is not even as large as Yanhui Mountain.

Big and very steep.

It took him almost no effort to climb this small hill, and it didn't bring any surprises to Lin Chou.

There are indeed patches of coconut groves and lemon trees at the foot of the mountain on the other side of the island. You can even see coconut crabs forming an army-like phalanx crawling around on the ground picking out the most delicious coconuts as trophies, but there is no such thing.

There is no trace of any stream.

No fresh water means no wood frogs.

Sighing again, Lin Chou sat down on the strange-looking stone and began to be in a daze.

By the way, you can also see people from the scientific research institute busily arranging various instruments at the foot of the mountain. It seems that their main purpose is this bare small mountain peak rather than the entire island. The circuits of various instruments are combined to form regular rules.

Each corner of the octagon is an instrument, and a large curved pancake-shaped object is erected high in the middle, a bit like the phased arrays on the towers that can be seen everywhere in uptown.

Lin Chou made a very unprofessional guess that this thing should be used for sending and receiving signals.

There are eight such octagons in total, distributed in various directions at the foot of the mountain, and the connecting lines between them form a larger regular octagon. At least to Lin Chou's alienated eyes, it is indeed a regular octagon.

This shape gave Lin Chou a very subtle idea that they wanted to blow up the island more than conduct scientific research.

I scratched the back of my head and stood up to prepare to go down the mountain. Unexpectedly, the mysteriously shaped boulder under my butt rolled away from the top of the mountain with a rumble as if it had been greatly stimulated.

"What the hell?"

The most important thing is that the big guy with a diameter of four to five meters is still rolling very roundly, and the speed is getting faster and faster, and dust is flying in the air.

"The one below!! It's downhill~"

Lin Chou's voice was very penetrating. The people below reacted immediately after hearing it. A long-faced evolutionist easily carried the rocket launcher under his feet on his shoulders.

"boom!"

With a warm smile on his face, he waved to Lin Chou repeatedly in the light of the explosion.

"Thanks~ We can't afford to pay for the equipment if it is damaged..."

"No..."

Just as Lin Chou was about to say something, his feet suddenly lost balance.

When he looked up, his first feeling was that he had fallen into a well, and his second feeling was that this was a volcanic crater?

The sky, which is as big as the mouth of a well, is getting smaller and smaller, and finally becomes imperceptible, while the surrounding space is getting wider and wider. From being more than one meter wide at the beginning, it is now dozens of meters wide.

Lin Chou glanced down and felt nothing except being filled with wind. It was pitch black.

It's pitch black, which is good. At least it can prove that this is not an active volcano, so that you won't even be able to find the ashes.

So Lin Chou turned his back to the sky and fell downwards with confidence. This was a very good technique. Relatively speaking, the buttocks were plumper than the face and could withstand stronger impact.

At times like this, it always feels like time passes unusually...slowly. When Lin Chou was so bored that he even wanted to recite a poem,

"boom!"

A weirder sound than a big sack full of beans falling from a thousand meters high and exploding into a shower of beans that spread in all directions and carried echoes.

I turned over and climbed up from the pit. I could see the sky as big as the mouth of the well before, but now I couldn't see anything at all.

Lin Chou didn't panic. At worst, he could just shovel a hole and rush out when summoned, not to mention he still had this fur ball in his pocket.

"Jigujigu?"

The fur ball rolled out of the chest pocket as if it was sensing something, and landed on Lin Chou's shoulder. Lin Chou then pinched it, "It feels good," and pinched it again.

Furball protested solemnly, "Chi-chi-chi!"

Lin Chou stared around and looked around. With his good eyesight, he could see hundreds of meters away at the bottom of the cave with weak light. Of course, the underground cave he fell into that resembled a volcano was only a few hundred meters away.

Within the radius, the ground composed of large and small weathered gravels still has a large crater left by Lin Chou's fall, which is more than half a meter deep.

I rubbed my butt subconsciously. Well, it was indeed stronger than my face, but it still hurt a little.

"Huh? Is there moisture?"

Lin Chou walked towards one side of the rock wall. This rock wall was covered with cracks as wide as a finger. It was obvious that moist water vapor was pouring out from the cracks. When he got closer, he could even hear "woo woo"

"The sound of the wind.

What does it mean for a skilled artist to be bold? Lin Chou is it!

This is an island, and I don’t know how deep it has fallen. There may be sea water behind the wall. If you don’t move even for ordinary people, you might be scared.

Fortunately for him, he went up and punched the stone wall with a bang, causing sparks and fragments to fly in all directions, and then collapsed suddenly.

A dirty stream of snot-like water stained with dust flowed under the feet, and the whining sound became twice as loud.

This is a horizontal cave-like cave. The air is very humid, and the rock walls are even dripping with water droplets. The rock walls below are very smooth and become narrower as you go up. At the top, it is only a dozen meters high and is completely connected into a mountain.

crack.

Lin Chou poked the fur ball,

"Little guy, have you seen Journey to the Center of the Earth? No? What about Adventures in Wushan? No? Poor kid."

"Many old movies played in alleys will teach you the philosophy of life. For example, these two movies made me understand two truths since I was a child."

"First, there are always treasures where you can't see them."

"Second, a bald head can do anything."

Maoqiu wouldn't answer him anyway. After Lin Chou checked his luggage to make sure there was nothing in the most important pot, he walked deeper into the cave with confidence. He had put his backpack on his stomach just now.

The "Woo" sound is getting louder and louder, which means that the airflow in front is very fast, and you can already feel the wind blowing from behind to the front. In addition, there seems to be the sound of water coming from the front.

I don't know how far I walked, but the sound of the huge water flow could almost be called a roar. After turning a narrow right-angled bend, my eyes suddenly became bright, and a hanging silver curtain broke the cave in half.

Lin Chou was stunned,

"Waterfall? Where did the waterfall come from..."

But he didn't think much and jumped up.

"boom!"

Who would have expected that behind the waterfall illuminated by light would be a solid stone wall.

Lin Chou slid down the smooth wall and then fell onto the water with a splat.

The water surface seemed to turn into an extremely soft blanket, rippling slightly, "holding" Lin Chou in his arms in the most comfortable posture. This feeling was very much like a cradle. If someone casually hummed a soothing and vague song, he would be stunned.

I could fall asleep on the spot.

However, the waterfall hanging above continued to pour water into Lin Chou's mouth without mercy.

"Bah, bah, salty? Is this sea water?"

Looking up to the sky, he realized that the waterfall was like a knife cutting the mountain wall into deep grooves. The cave he came out of was not located behind the waterfall, but on the side. The feeling just now was just a visual dislocation.

When Lin Chou turned around to find the source of the light, he was completely shocked.

The first thing that catches the eye is the vast and floating "ocean" that stretches across the top of the field of vision.

Yes, the truly blue sea is endless as far as the eye can see.

The ocean seemed to be covered by an invisible layer... Well, Lin Chou could see clearly. It seemed to be a glass or crystal-like barrier that isolated the sea water from above. Moreover, this transparent structure was like a big screen, stirring all the time.

The gorgeous auroras are thousands of meters away from the ground.

The blue of the ocean and the ever-changing aurora combined the colors on the crystal barrier, creating an indescribable magnificence and majesty, while on the earth below, within sight, there were clusters of huge crystal stone jungles.

At this moment, Lin Chou seemed to have left the earth, as if he had arrived in a dreamlike alien world.

The deep pool formed by the impact of water under the waterfall rushes out from the crack, forming a clear stream. From a distance, it looks like a blue ribbon in the crystal jungle.

"mmp."

Lin Chou praised the beautiful scenery here and walked along the stream towards the interior of the Crystal Jungle without hesitation.

He can walk on water faster and with less effort than on land, and he can even choose to move forward at a constant speed with the current even if he doesn't move at all, which is very convenient.
