The inside of the volcano may not look like what many people think.

It was hollow, like an iron box, filled with hot lava.

Magma is actually a silicate substance that melts into a molten state due to high temperatures, and it also shows different colors depending on the temperature, and the higher the temperature, the lighter the color.

Illuminated by the flames, the magma reservoir buried beneath Yellowstone is a colorful underworld.

In addition to the red magma, the mountains of the magma reservoir are mainly red and yellow.

The yellow ones are sulfur, and the red ones are iron minerals.

In addition, there is some black material at the top of the magma reservoir, which is the surface of the stone body formed by the cooling of the gas.

The Yellowstone supervolcano erupts every 600,000 years, and the last time was about 630,000 years ago, so the supervolcano is now in an eruption cycle and could erupt at any time.

Scientists have used computers to perform simulations......

If a supervolcano erupts in Yellowstone, 90% of the population within a 1,000-kilometer radius will not survive, and most of them will die from the solidification of their lungs due to the ash inhaled.

In other words, most of the country's territory will be directly killed, and there is no possibility of survival.

After a volcanic eruption, the ash emitted by the magma will drift to every corner of the earth within two days.

Then came the arrival of nuclear winter.

Thick volcanic ash obscured most of the world, sunlight could not reach the earth, a large number of plants and animals began to die, and black acid rain enveloped the world.

This process can last at least three to six months.

Other words......

Once the supervolcano erupts, not only the United States will suffer, but the whole world will fall into a food crisis.

This point has already been demonstrated in the disaster blockbuster "2012".

……

Chen Xi was not a geologist after all, so when he chose the alchemy site, he only cared about finding the largest volcano, and did not consider other issues at all.

The elixir has been tempered to the last moment.

Chen Xi was suspended on the top of the magma reservoir, and the ball of light directly below was the furnace of heaven and earth that he had laid out.

Besides.

He also set up a Great Spirit Gathering Array here.

With Yellowstone Park as the center, all the spiritual energy within a radius of a hundred miles poured into it, so that the entire magma reservoir was filled with a rich heaven and earth spiritual energy.

It's like a balloon that has been stretched to the limit, and it can explode at any time......

The lava is rolling, and the earth is churning.

Heaven and earth are furnaces, and aura is carbon.

Under the continuous calcination of the earth's fire, the medicinal properties of the Utama Bharata flower were completely released.

Once the elixir is formed, the prohibition will fall apart, and the aura of heaven and earth that has been compressed into a mass will explode in an instant, and its intensity will be no less than a large tide of spiritual qi.

Even more ferocious, more surging, and more threatening than the aura tides.

Chen Xi waited patiently, all his attention focused on the ball of light.

Suddenly......

There was a faint cracking sound from the top of the magma reservoir.

'Click', very faint.

Before Chen Xi could even react, this faint cracking sound turned into a loud 'boom' sound.

It was as if the earth had been torn apart.

Immediately after, the volcanic passage that had been deposited for hundreds of thousands of years came back to life.

The intense air pressure is constantly rising, trying to find a way to vent.

The mountain could not withstand the pressure, and huge cracks appeared and spread all the way to the surface at a rapid speed.

The cracks are getting bigger and bigger.

Countless boulders continue to fall from above.

The moment the boulder crashes into the lava below......

The magma is boiling and the fire is splashing!

Chen Xi was stunned.

Until this moment......

He hadn't even realized what a terrible thing he was doing.

The earth began to tremble.

Under the action of air pressure, countless cracks were torn into the interior of the mountain.

Cracks reach the surface.

In a flash......

Yellowstone spews out countless geothermal fountains at the same time.

Because the temperature is too high, the snow on the surface of the ground undergoes a sublimation reaction, turning from a solid to a gas in an instant.

A fog that obscured the park shrouded the park.

At the same time, several cities around Yellowstone sounded earthquake alarms at the same time!

The tremor was felt more and more intensely.

This is not an earthquake, but a ......

The supervolcano is coming alive!

Under the action of air pressure, the weak surface began to rise, and it also rose and fell strangely like waves.

Birds cry and beasts howl.

Countless animals fled from the park, and flocks of birds swept through the sky.

The only thing to be thankful for ......

Probably this is when Yellowstone is not open to visitors.

It's freezing in this place, and there are few people except for a few park staff.

Chen Xi was inside the magma reservoir, and what he saw was naturally more detailed.

He saw the mountain collapse.

Also saw magma boiling.

Originally, I just came to pick up medicine happily, but I didn't expect to witness a volcanic eruption.

Chen Xi finally realized the seriousness of the matter at this time.

But just as he was about to find a way to curb the eruption, the elixir came out without warning.

The surging aura that suddenly erupted actually forced him back several steps.

Seeing this, Chen Xi couldn't help but let out a long roar, followed by a sudden rush towards the ball of light.

It was not easy to wait until the elixir was released, if he really fell short at such a time, then he would not be depressed to death?

The aura turned into bursts of wind, like a sharp blade, constantly slapping on Chen Xi's body.

Rao is his cultivation to the world, but at this moment, he can only barely resist the pressure, and then slowly lean towards the spirit pill.

The elixir was quietly suspended in the middle of the cave.

Like a pearl in the night, it shines brightly.

After such a long time of extraction, the medicinal properties have been fully exerted.

As soon as it was born, the magma reservoir was filled with a refreshing smell.

Just taking a deep breath of the aroma will give you a feeling of clarity and comfort.

The elixir is right in front of you.

Thinking of the medicinal effect of this pill, Rao is Chen Xi couldn't help but be slightly excited.

As long as you take such an elixir......

So Yingying stepped into the heavens, and condensing the golden pill is almost a sure thing!

In a moment of excitement, Chen Xi also took out the strength to eat, and a burst of true vitality that was no less than the tide of spiritual energy instantly erupted in his body.

Qi was like a sharp knife, leading Chen Xi all the way to the location of the spirit pill.

It's just that with every step, the true element in his body will consume a layer.

Finally.

Chen Xi flew to the vicinity of the elixir.

The moment his fingers touched the elixir......

The surging aura in the magma reservoir was as if it had heard a call, and all of it merged into the elixir.

The stress is gone.

However, Chen Xi didn't have time to be happy......

The hot lava below spurted into the sky like a fountain.

Why hasn't the volcano erupted?

That's because the aura of heaven and earth filled the cave, thus pressing the magma into the magma reservoir.

Once Chen Xi took the elixir, the magma that had lost its suppression would shoot out like a dam bursting its embankment, even more ferocious and violent than before!

It was a burst volcanic eruption.

From a distance, it looks like a super-nuclear bomb dropped on Yellowstone.

First, a bright light lit up the sky.

Immediately after, a huge mushroom cloud slowly rose.

At the same time as the mushroom cloud rises, there are countless lightning bolts shuttling through it.

Angry volcanoes spew lava and smoke, and monstrous electric snakes bared their teeth in the air.

This is not a movie, but a joint performance of the sky and the earth -

Volcanic lightning.

A peculiar phenomenon that can only occur when a megavolcano erupts......
