Yellowstone's volcanoes, known as supervolcanoes, are one of the most destructive volcanoes on Earth.

Centered on the west thumb on the west side of Yellowstone Lake, it covers an area of 24 kilometers to the east and west and 80 kilometers to the south and north, forming a large crater area. About 8 kilometers below this, there is a magma reservoir with a diameter of 70 kilometers and a thickness of 10 kilometers, which expands every day. Once the pressure of this underground volcano reaches a critical value, a huge amount of magma will erupt, and at that time, the terrifying magma of thousands of cubic kilometers will engulf everything in the area of nearly 10,000 square kilometers, instantly changing the surrounding terrain, forming basalt and other rocks thousands of meters thick, and finally turning into a lava plateau with an altitude of more than 1,000 meters!

This is nothing, the most terrible thing is the volcanic ash that sprays into the sky, the amount of which can cover three-quarters of the United States, and in a few months the volcanic ash will cover the entire earth, the earth's temperature will drop by more than ten degrees, and the deadly cold climate will last for more than ten years, which can be called a catastrophe!

I don't know how many people will die because of it!

But Richard believed it had nothing to do with him – who could destroy the world by playing in their own backyard?

The magma in the ground is a backyard for him!

Richard could be sure that his penetration of the magma would never cause a magma eruption, and even if he did, his power would be enough to save a crisis.

So what are you waiting for, of course it's burrowing!

Richard took Jack and Hannah with him, and plunged headlong into the ground amid the screams of the two.

The earth and rocks around him splashed, and Richard was like a chariot drilling into the ground, and the earth and rocks melted one after another, as smooth as a hot knife cutting butter, and it went straight into the ground, which made Jack and Hannah amazed.

However, it soon became dark, and only the sound of rustling around them remained, and Jack and Hannah immediately tightened each other's hands, and then hugged Richard's armor tightly.

The distance of 8 kilometers was quickly broken through, and the surrounding area was instantly empty, and a large area of orange-red magma stretched as far as the eye could see, a spectacular sight that made Hannah cover her mouth.

"Ready? We're going into the lava. ”

"What? Really in? Jack was a little bit of a fool and then fell headlong.

It was Richard who rushed down with him.

"Don't—" Jack screamed.

On the side, Hannah was much calmer, but her little face was also a little pale, obviously excited and scared.

Seeing the scorching magma getting closer and closer, Hannah suddenly noticed something unusual. Not hot!

Being above the lava, she didn't even feel the heat!

This is...... The power of the dragonmen?

Hannah looked at Richard and her eyes fell on his blue eyeglasses, her eyes full of envy.

Is this what a superhero is......

Tong!

The three of them plunged into the lava.

The magma flowed around, and the invisible shield protected the three of them, in fact, mainly to protect Jack and Hannah, and Richard wanted to get in close contact with the magma and feel the power of the strongest fire on the earth.

He had an idea, maybe in this magma, he could upgrade his Yanlong armor!

Although the system annotation must reach the limit of its ability and qi in order to upgrade its armor, Richard always felt that there was more than one way.

But now, the safety of Jack and Hannah is more important, and if he wants to try to level up, he can come back later.

"How? Isn't it exciting? Richard patted the two of them, especially Jack, whose eyes were closed and trembling.

When Jack opened his eyes, he saw an orange-red patch not far in front of him, and swallowed violently.

"I ...... I'm in magma? ”

Richard laughed.

"Let's go, let's continue down and show you what kind of scenery is underground, whether the earth is empty or not." After Richard finished speaking, the three of them dived together.

The surrounding magma gurgled and stirred as the protective shield sank, and the scene was indescribably shocking, timid, or claustrophobic, I am afraid that I want to pee at this moment.

The magma layer, which was more than ten kilometers thick, quickly came to an end in Richard's slow sinking, and the three of them stood on the red-burned rocks with their feet on the ground, looking at each other.

So that's what lies underneath the lava?

Richard, of course, was not willing to stop there. If you want to see the inner world, then you have to see if the inner world exists or not, and whether it is empty or not!

Richard continued to use the technique of burrowing, trying to use the heat to melt a path, but the rock here was very strong and inherently resistant to heat, so Richard had to use more force. Fortunately, he was in the midst of magma, with an almost infinite power of fire to harness, and an endless heat for him to drive, and soon melted the rock into a large hole.

Richard led the two of them to continue diving.

Just a moment later, the rock vanished and a huge underground crater appeared.

Richard plugged the cave, and flames flew out of his palm, illuminating the surroundings.

It was a huge vertical cave with a diameter of 100 meters, which gave Richard the impression that it was a volcanic crater, but it seemed impossible that there was a rock layer above the crater, so this possibility was ruled out.

Falling, falling, falling, I don't know how long it took, Richard finally saw the bottom, so he took the two of them and landed on it.

Bottom?

Isn't the hollowness of the earth true?

Richard's perception spread, and the corners of his mouth curled.

Underneath, it's empty!

And there's a long passage!

This thing must be a gateway to Inner Earth, right?

As soon as Richard was excited, his feet suddenly unconsciously exerted force, and he heard a crackling sound.

"It's ...... Mica! Be careful! Don't move! Jack crouched on the ground and looked at the surface carefully, his face ugly.

"What is mica?" Hannah asked cautiously, her voice down to her throat, for fear of irreversible consequences if she was loud.

"It's a very fragile rock, and any slight change in weight and pressure can cause it to break."

"What are you afraid of, with me." Richard smiled and pointed to the hedron on the rock wall.

"Emeralds, rubies, and other things that look like diamonds or crystals, you can take some back as souvenirs."

Jack and Hannah's eyes lit up.

Richard suddenly chopped the mica rock layer under his feet, and in a burst of ice cracking, a large amount of mica broke and fell, and the dragon horse suddenly appeared to catch the two, Richard moved at will, and pulled off a large pile of gems from the rock wall and stuffed them into the arms of the two.

"Alright, the souvenir is in hand, and the trip continues!" Richard waved his hand, and the three of them flew downward.

I don't know how long it took, but a large number of suspended water droplets suddenly appeared in the passage, and before Jack and Hannah could ask, a large number of water columns appeared on the rock wall like water slides.

Tong!

The three of them rushed into the water, and the air hood appeared at the right time to protect Jack and the others as they continued to dive.

Soon, the water slide turned into an ocean!

Richard saw a cave not far away and swam over first. A moment later, the trio broke through the water and flew to the shore.

Richard removed the air shield, and Jack and Hannah jumped off the dragon pony and looked around.

"So there's water under the volcano? Is this seawater? Jack reached out to grab a handful of water for a long time, but Richard shot his brain.

Thanks to Richard's control of power is fine enough, otherwise this time it will be a bang in the sky.

"Look at it." Richard pointed to the sky, "That's a fluorescent bird, it can bioluminate, it's beautiful." ”

Jack looked up and was amazed by the fluttering blue glowing birds.

The fluorescent birds flew around a few times, and suddenly flew towards a cave not far away.

Richard walked over with the two of them, and the moment they walked out of the cave, they suddenly became enlightened.

The rocks, the ocean, the woods, and the huge air mass above the cavern that emitted a soft glow that did not shone brightly, burning like the sun......

Here it is...... The Underworld!?
