This little bit of fluorescence is continuous in the water, making the water crystal clear. It's like a swimming pool with underwater lights on.

It's a land full of fluorescent creatures. And the fluorescence that these creatures have evolved is different. The colors include red, orange, yellow, green, blue, and purple. But it doesn't seem abrupt and beautiful at all, and it is amazing, like falling into a dream.

Yun Lei helped Rao Ya and got off the boat, stepping on this land of fireflies that they had never expected. Where I landed, I felt that something was not quite right.

When I looked closely, I found that this firefly land was actually full of white bones!

Yun Lei picked up a broken white bone from the ground and found that the white bone was strangely shaped, and it didn't look like it was human. Moreover, the fracture of this white bone is quite stiff and rough. It seems to have been forcibly broken or twisted.

Among these bones, there are also some skulls. A few of them should be human skulls, others should be wolves, deer, monkeys, and some other creatures of the primeval jungle.

Not far away, there was also a highly decomposed corpse. The fur was rolled up, and he couldn't recognize his original true face, and he didn't know what kind of animal left the corpse.

Yun Lei couldn't help but think of the strong jolt when he was sailing just now - it seems that in a long time, this Shambala has not communicated with the outside world. It's just that almost no one can withstand these thousands of rock impacts. Even more unbearable, the last tens of meters of the cliff fell.

No matter what kind of living being, even if there is some spiritual wisdom and cultivation in the body. After being swept into the mighty underground river, there was no way to break free in the darkness. You can only go with the flow. Then he was hit by the oncoming rugged and abrupt stones, and he was knocked into a fool. Then, the bones and tendons broke and turned into a mess of rotten meat.

Then, like waste washed away by a sewer, it falls here, called here, the nourishment of these strange creatures.

Yun Lei picked up the strangely shaped, rough stubble broken bones, but saw that on top of the white bones, there were actually clusters of extremely small mushrooms growing like rotten trees by the river. There is nothing peculiar about the shape of the mushroom itself. It's not much different from the enoki mushrooms you usually eat.

However, the only difference from ordinary enoki mushrooms is the fluorescence of the mushroom. This is actually a mushroom that glows!

According to statistics, there are about 70 species of mushrooms that can emit light at night found in the world. It mostly grows in tropical and subtropical areas with low light, and can fluoresce in different colors such as light blue, light green or white in the dark or at night. The glowing parts of some glowing mushrooms are also different.

According to scientists, the fluorescence of luminescent mushrooms stems from an antioxidant called milkwood. After milk tree is converted into true luciferin by hydroxylase, fluorescein can fluoresce due to oxidation in the enzymatic reaction of luciferase.

The mushroom on the bone in Yun Lei's hand was crystal clear. Whether it is the cap, the stipe or the mycelium, it is a brilliant turquoise fluorescence. Such a scene is like a ghost fire, like the cycle of life and death.

Yun Lei is very sure, although the glowing principle of these glowing mushrooms should be similar. However, the mushroom in his hand is absolutely different. Whether it is the famous fluorescent mushroom, honey ring fungus, or night moon fungus, they all grow on rotten wood or tree trunks.

There is no one that grows on white bones.

Of course, this place is not without glowing mushrooms that grow on rotten wood, since there are a large number of animal bones here, there are naturally a large number of scattered branches and leaves from the outside world, and many pieces of rotten wood in the primeval jungle. These rotten woods also grow all kinds of strange mushrooms. Some of them, fluorescent flickering.

At this time, Yun Lei was surprised to find that in this underground space, which was much darker than the outside world, there were still plants growing. On some of the rocky outcrops, turquoise moss grows luxuriantly. Not far away, there are even clusters of low ferns growing close to the glowing mushrooms!

Rao Ya exclaimed at Yun Lei and said, "Brother Yun Lei, look at the water!"

Yun Lei looked in the direction that Rao Ya pointed and found that in the entire fluorescent river, next to the fluorescent algae, there was actually a large group of swimming fish whose eyes had not degenerated. The swimming fish swam around the fluorescent algae, devouring the fluorescent glittering algae, as well as some microorganisms that Yunlei and Rao Ya couldn't even see.

The swimming fish themselves have evolved transparent scales and translucent flesh. The volume is not large. In this glowing river, if you don't look closely, you won't be able to detect it. Come to think of it, this should be an evolutionary self-preservation.

Yun Lei was a little surprised: "In this underground world, the evolution direction of various creatures is actually not visualized. It's a real rarity!"

On a small island, as Darwin studied, storms often occur. Flying insects have only two evolutionary directions, one is that their wings are getting stronger and stronger to fight the storms on this small island. The other is that the wings are becoming more and more degenerate. It even degenerates to nothing, as a way to escape the effects of the storm on the wings.

In this dark cavern and underground world, this choice of completely different evolutionary directions is also valid.

These creatures that live in dark caverns and in the underworld either have more and more evolved eyes and evolved stronger and stronger to collect light and fight against the darkness. Either that, or the eyes are getting more and more deteriorating. Giving up the existence of vision in evolution, the perceptual systems such as hearing and touch have become extremely developed.

Nowadays, many dark caves that scientists have explored and investigated, and the evolutionary direction of the creatures in the caves is the latter. Therefore, it will become strangely shaped and transparent.

Until now, only this Shambala, discovered by Yun Lei, has fireflies that illuminate the entire underground space. There are creatures that not only have their eyes, but they are also extremely powerful. Although the fireflies in this underground space sometimes seem a little sparse and scattered, the brightness between the overlapping spaces is not low.

At least as bright as before dawn outside, or when it rains on a cloudy day. In some places where fluorescent mushrooms grow particularly luxuriantly, the accumulated fluorescent brightness can even compare to the sunlight outside!

According to plant instinct, photosynthesis and respiration go hand in hand. In order to survive, the energy produced by photosynthesis in the body must be greater than the energy consumed by respiration in the body!
