A storm came and went quickly, and when the fire was extinguished, the dark clouds in the sky dispersed, and the bright sunshine returned to heaven and earth.

The sky is blue, pure and flawless, not even a trace of white clouds exists, and the golden sunlight spreads down from the sky, where can you see the traces of the wind and rain?

Looking at the mountains, the rain and mist in the mountains and forests have not dispersed, ethereal and hazy, caged in the mountains, rising with the wind, dancing lightly under the sun.

In the eastern sky, a rainbow bridge spans the east of the island.

It was the small droplets left in the air after the rain that dispersed the sunlight and reflected the colorful beauty, and only they were still proving the existence of the wind and rain......

Cheng Fan glanced at the Hongqiao, wagged his tail, and continued his exploration on the island along a river flowing from the mountains.

In the mountains, there are no years, and adventures forget time.

Unknowingly, Cheng Fan has been on the island for more than half a month.

During this half-month, he has traveled to many places on the island, experienced many complex environments, and met many strange creatures.

The more places he walks on the island, the more Cheng Fan discovers the mystery and weirdness of this island!

The island's environment is extremely complex and varied, and there are lakes, mountains, valleys, swamps, and wastelands just where Cheng Fan has personally experienced.

Such a situation made Cheng Fan puzzled, obviously on the same island, how could there be such a changeable ecological environment?

Moreover, in these different ecological environments, there are also all kinds of strange creatures, such as the shadowless ghost shark in the sea off the island, the giant bull in the lake, the giant spider in the bamboo sea, and the King Kong ......

Recalling the environment he had passed through since entering the island and the various creatures he had encountered, Cheng Fan's heart was shrouded in thick questions, and he felt more and more that this island was not simple.

After half a month of traveling around the island, Cheng Fanyue felt that the island was not like a natural generation, but like a large experimental base, which was artificially isolated, divided into areas, and set up into different ecological environments, which were specially used to place and cultivate all kinds of strange creatures.

But if that's true, then who did all this? What is the purpose of doing this?

While traveling along the river, Cheng Fan encountered a large octopus at night, which was much smaller in size and different colors than the North Sea Monster.

The North Sea Monster has a large, black body, and this octopus has a flesh-and-blood color, similar to the muddy and rushing water, these guys usually hide in the river, and it is very difficult to find.

If he hadn't been on the river one night, he was making a fire and the octopus was coming out of the water to attack him, he wouldn't have noticed that there were so many monsters lurking in the river.

When he studied the octopus carcasses, he was surprised to find.

Regardless of their size, each of these octopuses looked exactly like the North Sea Monsters he had ever seen, carved out of the same mold, but not that big.

What do these octopuses have to do with the North Sea Trolls?

Cheng Fan left deep doubts in his mind.

The North Sea Monster is a legendary sea monster that has been in the world for thousands of years, which means that the years of existence of these octopus monsters can be traced back at least thousands of years......

Along the river, at the end, there was a large swamp, the water of the swamp was muddy and dirty, and it smelled of disgusting rancidity.

There are many green weeds floating on the surface of the water, with the waves of the water, constantly undulating, the water grows a variety of large swamp plants, the leaves are thick and turquoise, not modern vegetation, but ancient ferns, these plants are distributed in clusters in the water, bringing a bit of fresh green to the turbid and foul-smelling water.

In the swamp there is not only water, but also large black silt and small hills, on which many trees grow, but there is a lot of water here, and the leaves of many trees hang down to the water.

Perhaps due to the stench and decay, there are a lot of flies in the swamp, and these guys are amazingly large, one is only the size of a wasp, and they are constantly flying back and forth in the swamp, "buzzing", which is very annoying.

Cheng Fan has encountered several strange creatures in the swamp, the Gu's fish, the swamp monitor lizard, and even the long-disappeared emperor crocodile and the overlord salamander.

These creatures are all fierce and powerful, and they are also among the top predators of the era in which they live.

However, in this turbid and foul-smelling swamp, what Cheng Fan remembered the most was not the emperor crocodile hidden in the water, nor the elusive overlord salamander rolling in the big swamp, but a strange bird!

Four-legged, black, and piercing with harsh calls, the birds live in groups, perched in hundreds and thousands on a leafless, leafless, bare tree in the swamp.

It is not quite accurate to say that it is a bird, and in appearance, this creature resembles a bird's composition, more like a pterosaur, but it is much smaller than a pterosaur, and its body is covered with jet-black scales.

This strange bird is the predator at the top of the swamp, the overlord of this sky!

Cheng Fan once saw a group of strange birds preying on the overlord salamander in the swamp.

Hundreds of strange birds flew down from a bare tree, spread their bat-like wings like a dark cloud, and then swooped down like sharp arrows towards an overlord salamander in the swamp.

When the overlord salamander encountered an attack by a group of birds, its first reaction was not to fight bravely, but to flee in fear, but it did not escape in time and was pecked by the sharp beak of the strange bird.

The overlord salamander resisted desperately, biting with its mouth, scratching with its claws, and pumping with its tail, which injured many strange birds.

However, the next scene subverted Cheng Fan's cognition.

Several wounded and bleeding strange birds took off into the air again, their bodies burning with blue flames, exploding into blue fireballs in the air, falling from the sky, like a meteor rain in magic, madly smashing into the earth!

"Boom" "Boom" "Boom"

There was a big explosion in the swamp, the blue fire soared into the sky, the silt and sewage were blown up for several feet, and the emperor crocodile and the overlord salamander hidden in the swamp scattered and fled.

When everything was calm, the overlord salamander was completely dead, and the remaining strange birds rushed forward and pounced on the corpse of the overlord salamander, but in just a few breaths, a prehistoric overlord overlord salamander was gnawed into a pair of white bones.

After the hunt and food, the birds immediately flew away again, returned to the tree, stretched their wings, and seemed to remember their former glory in the afterglow of the setting sun.

Unfortunately, powerful technology has locked the genes in their bodies, and none of them have evolved into the sky overlords they once had......

Even, until now, only in the legends and myths of the West can we vaguely find bits and pieces of their past.

When Cheng Fan walked through the swamp, he was also attacked by this strange bird, but fortunately, he was prepared, but the strange bird made him kill a lot.

The corpse of the strange bird that fell from the sky, Cheng Fan saw the whole picture of this strange bird clearly.

The strange bird is extremely ugly, probably because it has lived in this swamp for many years, and it is covered in mud and exudes a disgusting stench.

Judging from the appearance, they are very similar to the pterodactyls that Cheng Fan has seen in the movie, the upper beak is sharper and longer than the lower beak, and Cheng Fan has tested the strength of the beak, which is as hard as steel.

The blood they come out is not red, but black, and they smell a faint smell of wine, and soon after the blood comes out, it will burn automatically, and release a strange fragrance that paralyzes the nerves.

Cheng Fan faintly felt that the Gu Fish, Overlord Salamander and Emperor Crocodile inhabiting the swamp were actually deliberately put into the food of these strange birds!

After passing through the swamp, Cheng Fan walked into a dreamlike forest.

In the forest, every grass and tree is crystal colored, but the grass and trees are not tall, even the tallest trees are not more than two meters, not to mention the flowers.

The forest is like a miniature secret garden.

There is no daylight here, only eternal night, illuminated by a round of silvery moonlight, exuding an incomparably dreamy beauty.

The forest is very cold, Cheng Fan walked in it, his body was covered with layers of frost, and the temperature here was even colder than the North Pole.

But the strange thing is that except for the frost and snow on his body, there is no frost, rain and snow in the forest.

The earth was a crystal of soft sand, and under the moonlight, it was also silvery.

There are no animals in the forest, and the silence is frighteningly cold, but with a gust of wind for no reason, the flowers and trees in the forest will shake with the wind, and a pleasant music will be played in the silver moonlight.

I can't describe the beauty of that kind of music, from the ears to the body, resounding in the depths of the soul.

When the music plays, the crystal flowers in the forest will quietly bloom, spilling out crystal pollen, floating in the forest and flying in the sky under the moonlight, making the whole forest seem more hazy and dreamy.

When Cheng Fan first walked into the forest, he thought that these crystal-like flowers and plants were not plants, but they were all works of art made of real crystals, but when he really came into contact with these flowers and grasses, he found that they were real life.

They grow, they bloom, they bear fruit, and they experience everything a life should be!

This is a miraculous forest, not a fairyland on earth.

When Cheng Fan walked to the end of the forest, he saw a big river that had dried up on the ground for an unknown length of time, and the river didn't know how many years it had been dry, and he couldn't see where it originated and where it flowed through at a glance.

On the other side of the river, the endless wasteland was exposed in front of Cheng Fan's eyes.

It seems to be the opposite of the eternal night in the forest, the sun that never sets in the wasteland, hangs there forever, as if the night has been pulled away from here, leaving only the eternal and endless day......

Cheng Fan has been walking in the wasteland for a long time, looking up at the sun in the sky, the sun is forever hanging high, hanging in the sky, obviously so far away, but he can still feel the endless light and heat it emits.

According to the heat coming from the body and the soles of the feet, the temperature here is more than 100 degrees.

Moreover, there is no wind here, not even a little air movement seems to be there, as if it is locked by an invisible force, and the heat is imprisoned here, and it can only enter and not leave.

The Crystal Forest and the Eternal Day Wasteland are completely two realms, and heaven and earth have suddenly become a melting pot here, Cheng Fan even wonders if this is the refining ground of gods and demons, otherwise there would be such a stark difference.

The desert is very large, Cheng Fan walked for two days and didn't see the end, all he saw was the vast wasteland, under such high temperatures, there was no vegetation, no animals, only rolling sand grains in the sun.

Occasionally, in the buried yellow sand, Cheng Fan will see some bones, these bones are very large, the year of death is impossible to judge, Cheng Fan tried, gently pushed, these bones will be scattered into a pile of bone residue.

The further you go into the depths of the desert, the higher the temperature, the more and more bones you see on the road, each of which is at the level of a supernatural beast, but it falls here and dies on this island!

What happened here back then? What is the mystery of this island, or this planet?
