Although the picture taken by Li Bai with the high-end domestic mobile phone that Li Bai bought for Qingyao Demon Girl is clear, it is played back on the palm-sized mobile phone screen, and the visual effect is still poor.

After he got the video file out, he played it directly on the TV.

Even Li Bai didn't expect that the picture taken by the Qingyao Demon Maiden was not underwater, but an underground space where air, animals and plants existed.

As far as the eye can see, it is a sparkling blue lake filled with colorful corals, shellfish, and a variety of aquatic flora and fauna.

In the extreme distance, the existence of the rock wall is faintly visible, the camera is raised, and the dome hundreds of meters high is actually overgrown with plants, many vines hang down, and the longest is almost close to the water.

As the camera moves quickly, the most striking thing is that a large transparent crystal is embedded in the center of the dome, emitting a bright light.

There is light, air, water, animals and plants, just as the news report speculated, it is an ancient secret realm isolated from the world, and it is more mysterious than the peach blossom spring.

Not only that, but on the edge of the blue lake, there is also a large area of cliff heights, with dense vegetation, and what is even more surprising is that there are artificial traces.

The tall building made of rough boulders has traces of the vicissitudes of the ancient flood era, and some of the traces of manual excavation even extend to the stone wall connecting the dome.

The video shot by the Qingyao Demon Maiden is not long, only a short ten minutes, which is not enough to completely capture the entire picture of the underground ancient secret realm, but these pictures can still make people shocked.

After watching the video, Li Bai deleted it all without hesitation.

Once it spreads, not only Huxi City will immediately become the focus of the world, but even he himself will get into great trouble, even far more than the turmoil caused by the red jade carp.

"In recent times, you are not allowed to go back, not even closer. ”

Li Bai pondered for a moment and solemnly warned the two demon girls.

The prehistoric Devonian overlord Deng Shi Yu appeared alive in front of everyone's eyes, I am afraid that there are countless eyes staring at the "Big Blue Hole", Qing Yao and Hong Li, even if they carefully hide their figures, it is still difficult to guarantee that they will not be noticed.

"Childe, don't worry, the slave family won't take Sister Hong Li there again!"

Although Qing Yao was reckless, she was not stupid, she knew that Li Bai Fangcai's warning was because she had abducted the stupid little red carp to explore the "big blue hole", after all, the water was Hong Li's home field, and she was not afraid of any danger.

Li Bai knocked on Qingjiao's head and said, "It's good that you know it in your heart!"

But I heard the demon girl smile and say again: "There is more than one entrance and exit in that place, if the son wants to go, the slave family can take the son to enter from another place." ”

"More than one entrance?"

Li Bai's eyes widened in surprise, he had always thought that the "Big Blue Hole" in the Nine Creeks and Eighteen Streams was the only entrance.

"There is a crack connected to the water exchange culvert of the South Lake, not far from us, and this is the credit of Hong Li, if she hadn't noticed the change in the water flow, I wouldn't have found such a hidden place. ”

Qing Yao and Hong Li's "Big Blue Hole" and their party seem to have gained a lot, and they can actually find a second entrance.

Nanhu District is named after Nanhu, the most famous tourist scenic spot in Huxi City, with a vast water surface, lush vegetation and pleasant scenery, just like an emerald on the southeast coast, which attracts countless tourists every year.

In ancient times, the South Lake was a bay, but as the sea changed, it gradually became isolated from the sea, and over the years, the rain accumulated, and finally became an inland freshwater lake.

However, the rainwater of the surrounding streams alone is still not enough to maintain the existence of the South Lake, and over time, there have been many siltation blockages, and if it were not for the dredging of generations after generations, it would have almost disappeared into the long river of history.

Nowadays, the south is connected to the Qianjiang River in the north and the canal in the west, turning from stagnant water to living water, and there is no need to worry about siltation and deterioration of water quality.

"When you're done eating, take me to see it. ”

If he could avoid people's eyes, Li Bai didn't mind going to that ancient secret realm to explore.

After all, although the aura emitted by the "Great Blue Hole" is not as good as the secret cave of the other world, and it is even far inferior to any place where the aura gathers, but in this world where the aura is exhausted, it has become extremely valuable.

Li Bai could guess that the reason why the little demon girl of Hong Li appeared in the Nine Creeks and Eighteen Streams, instead of appearing beside him like Qing Yao, was most likely subconsciously attracted by the water-based aura, and finally deviated from such a distance.

However, how exactly did one person and two demons cross the plane, they were still confused, and there were no clues at all.

"With Hong Li, as long as there is water, you can go as you like. ”

Hong Li's demon girl succeeded, found an excuse for herself to abduct Hong Li, and successfully passed the test here in Li Bai.

-

The turbid water of the river flows slowly, and from time to time a fish waving its head and tail swims downstream.

A bubble with a diameter of nearly a zhang wrapped Li Bai as he walked quickly underwater, the frog coiled on his shoulder, and a red carp in front of him was suspended in the air, controlling the bubble to trigger the flow of water.

Although there was a fist-sized ball of light that released a flood of white light, no less bright than a 100-watt incandescent lamp, but underwater, it still couldn't shine two meters away, and it was all based on the natural instinct of the little demon girl who could easily go against the water, and would not bump around like a headless fly.

The bubbles looked very weak, swaying slightly in the process, but they never let a drop of water approach the two demons.

Using a spell to make his figure become trance-like, intersecting with the surrounding shadows, and avoiding the ubiquitous city surveillance cameras, Li Bai took the big and small demon girls near the mouth of a water exchange culvert in Nanhu Lake, and directly plunged into the water.

In terms of underwater activity, even Qing Yao, who has the cultivation of the Demon King of the Destruction Realm, is still not as good as the Great Demon Hong Li of the True Dan Realm who is one level lower.

After sneaking for more than an hour, the water flow slowly became clear, and the range illuminated by the light ball expanded to more than ten meters away, and it could be clearly seen that a bathtub-sized hole was gushing out clear water continuously, discharging the turbid Qianjiang River aquatic life and forming a clear water area.

If it weren't for the two demon girls discovering the abnormal changes in the water flow, they wouldn't have found that in addition to the nine streams and eighteen streams, there would also be a hidden salty water gushing outlet here.

"This is it!"

The Qingyao Demon Maiden once left her own mark, and there is no doubt about it.

"Hong Li, take us down. ”

Li Bai folded his arms and let the slender bubbles wrap around him and rush into the bathtub-sized hole.

The cave is very narrow, only allowing one person to drill through, and the water flow speed is much faster than the "big blue hole", but for Hong Li, it is not a problem at all.

The bubbles carried one person and two demons against the water, without any influence at all, turning left for a while, turning right for a while, the space in the cave was big and small, sometimes it could accommodate a bus, sometimes it was only the size of a cup, and it needed Hong Li to control the water impact and expand it to let Li Bai pass through.

Half an hour later, the underground space suddenly opened up, but it became like a labyrinth, with stone pillars of different thicknesses, the short one was one meter high, the long foot was forty or fifty meters, and there was dark blue salt water on all sides, almost indistinguishable from the top and bottom, left and right, and occasionally some aquatic animals and plants could be seen.

The speed of the bubble became faster and faster, and after turning around, it burst out of a thick crack in the ground, and a faint glimmer of light could be seen above.

As it continues to rise, the surrounding salt water becomes brighter and brighter, changing from black to dark blue and then to dark blue, and the air pressure inside the bubble does not change from beginning to end, and there is no decompression damage caused by the rapid rise.

A few minutes later, the sound of water rattled, and Hong Li and Qing Yao finally rushed to the surface of the water, as if the bright light of noon was sprinkled overhead, and there was still a trace of heat in the light.

The magical crystal, which was larger than the house, was the source of life for the entire underground space, and without it, there would be no abundance of flora and fauna thriving in a near-isolated environment.

When you're on the ground in person, it's very different from watching the video on your TV screen.

The air is filled with a pungent salty smell, very humid, from time to time water droplets fall from the dome, and those hanging vines also play a role in condensing water and replacing clouds to rain, forming a special meteorological circle.

Perhaps due to the high air pressure, the air is a little stuffy, and the dome is about hundreds of meters above the water.

Releasing a flying sword in his hand, Li Bai stepped on the sword and flew towards the cliff where the rock building was found.

As soon as the front foot left, several huge figures appeared under the water, swimming slowly, but it was still a step too late, and by the time they arrived at the water, the flying sword had already landed on the cliff.

Perhaps due to the change in air pressure, the almost vertical cliff face still leaves clearly visible water marks, dense shellfish and corals.

It may be because the "big blue hole" was dug out in the nine streams and eighteen streams, the pressure was vented, and the air expanded, squeezing out part of the salty water of the ancient sea layer, causing the water surface to drop by more than ten meters.

The area at the top of the cliff that Li Bai saw in mid-air was wider than the picture taken by the Qing Yao Demon Maiden with her mobile phone, and many of the plants were ancient ferns, perhaps because such an environment was more suitable for the growth of ferns, and many tall ginkgo biloba could be seen during it.

Compared with the saltwater lake under the cliff, the area of the cliff top only accounts for about 30% of the entire underground space, which is faintly in line with the proportion of 7 parts of the ocean and 3 parts of the land on the earth's surface.

Several tall rock buildings are scattered among the towering trees, one of which seems to have been hollowed out of a single boulder, and there is no trace of the pile.

"There used to be human beings here. ”

Li Bai found many stone tools, pottery, and even bronze and iron tools inside and outside the rugged buildings that had been overrun by mosses and fungi.

This means that there are not only prehistoric creatures in this ancient secret place, but even humans, but over time, the human race living here has gradually disappeared.

The most direct evidence of this is the frescoes left on the rock face, the traces of carved lines, and the ochre red pigment in the middle, even time and plants cannot completely erase their existence.

Although there is no text, the vivid mural records everything here more clearly and accurately than any text.

The human tribes planted, gathered, hunted, sacrificed, fought on the cliffs, and died out, like a picture scroll, slowly unfolding in front of Li Bai's eyes.

I don't know what time it was, two huge tribes fought in this area, and the battle of corpses everywhere angered the gods, and threw a snow-capped mountain into the world, destroying everything in an instant.

When the lucky few who survived the catastrophe woke up, they found that the heavens and the earth had collapsed, and the endless sky, endless sea, and endless land had all disappeared, leaving only everything they could see in front of them.

The remnants of the people are no longer divided into tribes, and they began to slash and burn here, slowly continuing the bloodline, life is extremely difficult, food is scarce, but they can barely survive.

The population is always growing, but whenever the space and storage on the cliff are not enough for everyone to survive, the tribe will organize the hunting of big fish, the whole process is more like a sacrifice, the old and weak are bait, the warriors fight hard, and at the same time get enough food while dying a group of people, this tribe that has been pinched together because of the punishment of the gods maintains the balance of population and ecology in this cruel way.

However, as time went on, the gods seemed to curse again, and the people of the tribe began to become disabled or demented, and the population became smaller and smaller, and eventually only a few people remained, and the tribe disappeared from there.

At the end of the mural, the increasingly coarse lines become chaotic and abstract, meaning that the last painter is no longer intellectually intelligent enough to continue this act of high civilization, and finally dies out completely.

The human civilization on the cliff may have lasted for four or five hundred years, and it was only a brief passerby in the entire underground space, and it disappeared in a blink of an eye.

Although there were no words, only murals, Li Bai still found some recurring symbols, especially before the murals showed that before the gods sent down the devastating heavenly punishment, there was a special symbol above the heads of the leaders of the two warring tribes, and one of them also repeatedly appeared on the heads of some special humanoids of the cliff tribes, perhaps representing the meaning of the leader.
