Removing all the moss and fungi, he was able to see most of the contents of the mural clearly, without any techniques, and the simple and simple scene reproduction made Li Bai sigh.

Although the human tribes trapped here are not completely cut off from food, nor do they have too ferocious natural predators, the ancient saltwater lakes are like inexhaustible treasures, and there are mineral veins to dig and smelt tools, in this unique environment of self-sufficiency, they are still no match for the vicious consequences caused by the reproduction of close relatives, and the entire tribe has undergone racial degradation and returned to ignorance.

The remains of bronze and iron tools can be found nearby, which means that the civilization level of the two warring tribes at that time was not low, but it was completely interrupted by the sudden snow-capped mountains.

Judging by the surrounding plants, it is clear that most of them are not adapted to cold climates, especially ferns, and it is intriguing where this snow-capped mountain that falls from the sky comes from.

According to the content of the mural, like two groups of ants fighting each other, the bear child, who was called the god by the ants, suddenly threw a snowball without warning and smashed it into the battlefield, but the snowball was extremely large, and it looked like a snow-capped mountain from a distance, and the aftermath caused by the fall still made the two groups of ants instantly wiped out.

Aside from the bear child god, it is still possible to restore part of the truth, the two tribes, the snow-capped mountains that fell from the sky, are the origin of the underground prehistoric human tribes.

Mountains don't fly around, and the murals are seen by prehistoric human survivors, but they are not what they are, so there is only one possibility, which is to fly from outer space.

There aren't many sources of ice and snow in outer space, Saturn's rings, asteroid belts, or comets.

Then the answer is obvious.

The ice of Saturn's rings is Xiaoice blocks, at most the size of a house, it is difficult to get rid of Saturn's gravitational circle, even if it is occasionally thrown out, it cannot penetrate the thick atmosphere, the asteroid belt has always been very stable, changing the orbit of motion, the probability of flying into the inner circle of the solar system is very small, hundreds of millions of miles away, countless difficulties and obstacles, often intercepted by other planets, the moon in low earth orbit is also a big barrier, if it is really an ice planet smashed down, the movement and the traces left will definitely not be small.

Then there is only one truth left, the comet.

The comet, which is not very dense, was originally a snowball, and its diameter was large enough to last until it fell to the ground.

In this way, the specific age can be roughly deduced.

Li Bai did not study this specialty, and he couldn't find any information to corroborate it for a while.

"Childe, what's painted on it, is it a treasure?"

The little red carp liked this underground space full of water-based aura very much, and wandered around, leaving only the Qingyao demon girl on his shoulders by Li Bai's side, it seemed that he wanted to find something good.

"It's also a kind of treasure, but it's invisible, and the stone wall is painted with history. ”

Li Bai told Qing Yao about the contents of the mural.

"Ah, the stars falling from the sky? or the stars of ice and snow, this is amazing!"

Rao is Qingyao Demon Girl has made up a lot of popular science knowledge in this world through the Internet, and she still doesn't know enough about some relatively unknown knowledge, but she still knows what the result will be when the stars fall.

Modern human society is also known as the information age, even if the learning ability is off the charts, they only dare to dominate in a small number of fields, and it is pure wishful thinking to master all of them without missing anything.

Although Qingyao is smart and can never forget, the contact time is still short, and most of what she can learn is limited to basic social knowledge, at least she knows that you have to swipe your card to get on the bus, you need an ID card to take a plane, and you have to have a passport when you go abroad.

Li Bai walked out of the five-story rock building with the Qing Yao Demon Maiden and looked up at the dome.

It is highly likely that the huge crystals that emit no less than the midday sun are not original to Earth, and may have something to do with the comets falling from the sky on the mural.

The density of the comet was originally not large, and it was not impossible for it to break under the huge impact, and it was not impossible to shake the comet nucleus inside out.

It's just that the nucleus of a comet that can release light and heat, and it can last so long, is a bit unusual.

But Li Bai was not too surprised by the strange things that fell from the sky. The Otherworldly Momen Hanging Island, like the innate treasure Chaos Qinglian, the natal magic weapon Xuanxing in his mind are all treasures that fell from the sky, and even heard that several well-known secret caves in the other world are simply smashed out of the stars in the sky.

The little red carp that was spinning around flew under the crystal at some point, and the red light flashed, and a pretty girl dressed in red with a bun stood out of thin air, reaching out to touch the surface of the crystal.

In an instant, the dazzling light released by the crystal suddenly dimmed, and quickly turned into a sunset at five o'clock in the afternoon, and the water-based aura that permeated the air flowed rapidly, converging towards the location of the crystal, forming a water and air vortex, and the vines hanging on the dome swayed slightly with the wind, moving with the wind, and also formed a vine vortex, and the saltwater lake below was turbulent.

Some of the vines can't help but pull, and the roots break away from the dome, or the branches and leaves break away, mixing with the water vapor vortex to form the sound of ghosts crying and howling.

The out-of-phase lasted for a full quarter of an hour, and the crystal lit up again, but Li Bai clearly noticed that its brightness was much dimmer than before.

The branches and leaves of the vines, which had lost their airflow, rained down on the water, and although the waves were calm, the water was still bustling, and many fish rushed to the shallow water, opening their mouths to tear at the delicious branches and leaves.

There is no shortage of food under the water, but the branches and leaves and rattans that fall from the sky are a rare meal, and some of the branches and leaves are accompanied by strange-looking insects, which are even more popular with fish.

At the same time as the vegetarian fish feasted on large chunks, the ferocious carnivorous fish also began their own gluttonous feast, and one level after another predator appeared, several black and swarthy huge figures set off waves, and countless fish flew out of the water, and the giant teeth like the door panel quickly opened and closed, whether it was vegetarian or carnivorous, as long as the body size was smaller than their own, they were all dishes on the recipe, even if they were of the same kind, there was no difference for the Dun's fish at the top of the food chain.

Li Bai stood on the edge of the cliff, quietly watching the changes in the crystal in the dome, and he could probably guess that this was the fate of the little demon girl of Hongli.

Qingjiao spit out the letter, envy, jealousy and hatred, and wanted to find a pot to stew this red carp.

In just a moment, the crystal suddenly became aura-pressing, as if it was completely condensed from water aura.

What's even more strange is that there is actually a trace of fire aura in the middle of the water-based aura, which is faintly combined with Hong Li's water and fire talent.

The girl dressed in red turned her head to look at Li Bai, with a look of joy on her face, withdrew her white and tender hand, and flew down from the dome.

As soon as she left the crystal three zhang away, the red light flashed, and the girl in red turned back into a spirited red carp and threw herself directly in front of the cliff.

"What did you find? ”

Li Bai noticed that the aura of the little red carp was much stronger than before, and the cultivation of the great demon was completely restored as before, and there was still a faint momentum to march towards the high level of the True Dan Realm.

At present, the rules of heaven and earth in this world are greatly suppressed, and the aura is stagnant, whether it is the cultivation of the human race or the demon race, it is more difficult than when it was in the other world, like a shackle, moving forward with a heavy load, without cultivation materials, even if it is talented, it is still a thousand points of hard work to get a harvest, and it is difficult to see the hope of a breakthrough.

It's really unexpected, in just a short period of time, the little demon girl of Hong Li was able to break through the shackles and take a step forward in her cultivation.

Qingjiao's face is full of jealousy, don't ask how you can see it, you can feel it by looking at her virtue, Xinzi doesn't spit out, and she grins with bad intentions.

However, with Li Bai present, there is no need to worry about this demon girl doing things.

In fact, Qing Yao's jealousy is completely unnecessary, her cultivation started earlier than Hong Li, but she was able to successfully transform into a Jiao with ordinary bloodline, and she was lucky enough to obtain a dragon body for a short time, and achieved the Demon King of the Breaking Tribulation Realm, which is many times luckier than ordinary demon clans.

The demon clan that used to be in the Kunlun Demon Domain, with its companions, is now long gone, and the battle between the demon clans and devouring each other is far more tragic than the battle between the human race's magic and martial arts.

But a demon girl is a demon girl, jealousy is jealousy, there is no need for any reason at all, if it weren't for the fact that Li Da Devil personally suppressed it, just such a lawless temperament, I'm afraid it would have started to cause trouble in the world a long time ago, but now it has obviously been taken away from the building, and even no one eats it.

"That spar can help me practice, and above the spar is magma. ”

Through the resonance with the dome crystals, the Hongli Little Demon Maiden discovers more secrets.

"Magma? Is this magma?"

Li Bai was a little shocked.
