According to Yun Lei's conjecture, perhaps, this lake with a radius of hundreds of square kilometers next to this huge underground volcano is an ancient existence that existed since the earth was just freed from the Wallenge Ice Age.

Moreover, after all kinds of catastrophes and all kinds of vicissitudes of life, it was fortunate to survive......

And this heaven and earth spiritual fire appeared in this ancient volcano, next to this ancient lake. It should be no coincidence. Perhaps, the appearance of this crater should be in ancient times, when the Nawalenge Ice Age collapsed and a large number of volcanoes erupted on the earth.

Perhaps, only the crater that has survived for such a long time can it finally give birth to a little spiritual fire of heaven and earth. And this point of heaven and earth spiritual fire may contain the vicissitudes of hundreds of millions of years.

Ordinary craters may also have earthfire and magma, but soon after the appearance of earthfire and magma, or after the eruption of the volcano and the release of energy, it tends to be cold. It always tends to be violent and cold. Few can remain peaceful, but they exist for a long time. It is even rarer to exist for hundreds of millions of years in succession.

Such craters, like cratons, are the oldest and most stable part of the continental crust.

Yun Lei and Rao Ya, feeling such a distant and ancient meaning, quietly waited for the fire magma of this earth, and in the volcano deep in the heart of the earth, a wisp of heaven and earth spiritual fire that had been bred for hundreds of millions of years appeared.

After dozens of hours of sleepless waiting. Yun Lei and Rao Ya, suddenly, gave birth to a strange sense. This induction has nothing to do with the changes in the aura between heaven and earth, and has nothing to do with the environment around this underground world.

I just feel like something has changed between heaven and earth. Yun Lei then knew that in the future of the full moon, something in the fire magma of this earth moved.

Rao Ya is now covered with the pure yin aura left over from the Ghost King's emptiness, and she is more sensitive to things that have the power to restrain her yin aura. Rao Ya's mind was in her consciousness, but she felt that something appeared between heaven and earth.

And in the hearts of Yun Lei and Rao Ya, after giving birth to this feeling, Yun Lei found that the magma that originally flowed out of the mouth where the magma erupted seemed to have become slower. And the movements when it flows have become gentler.

Originally, these quietly flowing magma were like streams flowing in the mountains. Then, at this time, the magma that slowly flowed into the sea became like a red cloth gliding slowly on the flat ground. It's beautiful, it's hot, but there's not even the slightest ripple!

Absolutely docile and silky! exactly like the Prussian expedition team member recorded in his notes!

Yun Lei and Rao Ya, but they felt that the heat between heaven and earth and next to the magma had calmed down in an instant.

At this time, Yun Lei and Rao Ya suddenly discovered that a trace of blue-blue flames suddenly appeared on these volcanic magma that had become extremely docile!

The blue-blue flame was very different from the magma that graded from orange to red, mixed with a little bit of gray mass that cooled and condensed on the surface when it met with air. This blue-blue flame was extremely light and beautiful, just like the color of the clear sky outside the sky.

It just fell straight into people's eyes and hearts.

Moreover, this blue-blue flame did not follow the burning method of the earth fire itself at all. Instead, it was very lively and arrogant to slip over the fire magma. The magma that flowed from high to low was like a slide of blue-blue flames.

This blue-blue flame descended from a high place, and in just an instant, it slid down to the place where the magma entered the sea, and the water and fire collided.

The magma entered the sea, where water and fire collided, and the magma that flowed into the sea had been exposed to the surface of the sea after slowly leveling the depth of thousands of meters. A new land was formed, condensed on the outside and blazing on the inside. It's dark. Some of them are exposed to the surface, while most of them are sunk to the bottom of the sea.

It's a delicate balance. Only the magma that sinks to the bottom of the ocean after being injected into the sea will burst into a roar in the instantaneous transition from heat to condensation, leaving a series of chemical and physical reactions on the surface of the sea to produce foam and white mist. Make the scenery of this place of fire and water strange and strange.

However, this flame, which seemed to be not much different from the temperature of the blue-blue flame in the gas stove at home, suddenly burst out with an inexplicable force when it fell on this new land where water and fire were fighting.

Between heaven and earth, the fog formed by the condensation of water vapor in the air due to the heat suddenly disappeared. This disappearance is not due to the fact that the water in the sea has cooled down and no longer has water vapor. It's because the heat between heaven and earth has risen sharply.

Then, the cooler air that was supposed to condense the water vapor is now hot.

This range has expanded to the skyline as far as the clouds and thunder can see. More than ten kilometers away in the sky, Yunlei could faintly see some white mist.

And the clouds of fluorescent mushroom spores that were originally floating in the air have dissipated completely!

At the same time, when this blue-blue flame appeared on the newborn land formed by the eruption of the earth-fire magma in this sea, the coastline at the junction of the originally vast sea and the land was actually retreated hundreds of meters so abruptly!

Of course, this retreat is not because this sea has also become a spirit and has its own consciousness.

It was because of the blazing evaporation! The sea water within a few hundred meters was completely evaporated by this flame when it fell and exerted its power!

After the coastline retreated a few hundred meters, in the underground ocean, some creatures that were originally hidden near the shallow sea revealed their bodies!

Among them, there are a variety of plankton that depend on the temperature of the magma entering the sea, and the nutrients brought by it, and a bunch of large and small fish. Some pristine sea creatures. Various shellfish, crustaceans and the like. There's even a plesiosaur chasing fish in the sea in search of food and intending to see if there's anything tasty to eat off the coast!

This plesiosaur was also considered to be smart. But being smart is mistaken by being smart. After retreating a few hundred meters from this coastline, this plesiosaur, a huge body that was seven meters long and weighed several tons, ran aground!
