"Can you sense where the sound is coming from?" King asked.
"It seems to be from below... a very, very distant place." Mumen Rider said cautiously.
Although his strength had undergone earth-shattering changes, he was still very wary of this matter.
"Then I understand." King nodded.
Every time a disaster occurred, Mumen Rider could hear this sound, and it came from below.
Then there was only one answer: deep within the Earth's core, there likely resided a god—a god belonging to Earth.
'So it turns out Vaccine Man was right.'
King recalled what Vaccine Man had said at the beginning, it turned out to be true.
"I am the incarnation of the Earth's will, born to eliminate you humans who recklessly destroy the Earth's environment."
"Interesting. Mumen Rider, follow me."
The corners of King's lips curled up slightly, he seemed to have found the root cause of the frequent disasters on Earth.
"King-san, where are we going?"
Mumen Rider looked puzzled, then Psychic power erupted from King's body, enveloping his form.
"I'm taking you to catch a ghost."
Whoosh!
King took Mumen Rider and headed underground, the hard earth instantly being forced apart.
"It's right down here."
King felt that increasingly intense aura and couldn't help but get excited.
Logically, gods cannot step into lower dimensions, which is also a form of protection for lower-dimensional creatures. But the one on Earth was an exception.
Combined with what Vaccine Man said earlier, King was very curious—could it really be a god born from Earth's will?
(101, what do you think?) King asked.
As a fellow god, and since 101 was constantly creating God's agents in preparation to rule Earth, the two sides might have had contact.
(Hmph!)
101 was clearly still angry about King keeping all the benefits to himself earlier, but it still thought about it seriously. After all, it was currently living under someone else's roof.
(I did once sense a different kind of power, but I'm certain that fellow isn't a god, but rather...)
(Rather what?)
(Something like the primitive will born from Earth.)
King's whole body shook. It seemed things weren't as simple as he thought. If it really was a will born from Earth itself that was constantly creating monsters, then things became complicated.
"Are humans really that disliked?" King muttered.
Nowadays, the human population on Earth had plummeted to less than thirty percent, and the ecosystem had recovered quite a bit. But humans are also indigenous inhabitants after all. Logically, even if Earth's will wanted to punish humans, it wouldn't go as far as total extermination, right?
"Forget it, I'll talk after I find that fellow."
King and Mumen Rider continued to dive toward Earth's core. When they reached a depth of ten thousand meters, the surroundings were filled with gold mines, but they didn't care about that at all.
It wasn't until they reached a depth of twenty thousand meters that King felt a barrier.
"Hmm? A barrier! There really is another world down here."
King was immediately excited, while Mumen Rider gulped.
When facing monsters, he had always moved forward courageously. Even if he knew he couldn't win, he would never retreat. But the unknown is the most terrifying thing. This trip of theirs might very well overturn human common sense.
"We've even slaughtered a god, why fear a ghost?"
Psychokinetic Impact!
King could feel the strength of the barrier and used Psychokinesis, attacking a single point.
Pop!
King's strength was no longer what it used to be. He easily broke a hole and then quickly led Mumen Rider through it.
Just as King entered the barrier, the damaged hole quickly repaired itself.
"This is...?! A world at Earth's core!" King's pupils constricted slightly.
The scene before him shocked him. There was no magma or volcanoes as imagined. What met his eyes was a beautiful scene like a hidden paradise.
"Who goes there?!"
Several figures rushed in front of King like streaks of light. They looked like humanoid dinosaurs, with sturdy builds about three meters tall.
"Really Subterraneans?"
King looked at the Subterraneans before him with interest. He remembered that Saitama once had a dream where Subterraneans invaded the surface and wiped out most of the humans. In that dream, the Subterraneans even injured Saitama, and finally, the Subterranean King appeared.
"Surface dwellers?!"
The Subterraneans' expressions changed drastically, and they slashed out with the longswords in their hands.
Clang!
A single finger easily blocked the longsword, making it unable to advance even a fraction.
"How is this possible?"
Subterranean Wrath!
The Subterranean seemed to realize King's strength and erupted with a powerful aura from within, its strength instantly rising several times over.
"Die! Foolish surface dweller!"
Rapid Light Slashes!
Swish swish swish!
Several slashes came head-on. King simply raised his finger slightly, and countless blue streaks of light pierced through the Subterranean's body.
"Ugh... How can this be!"
Green blood sprayed from the Subterranean's body as it fell toward the ground.
"They are somewhat similar to the Subterraneans that appeared in M-City before, but their strength is much greater."
King raised an eyebrow.
The strength of the Subterraneans before him was roughly around the peak of Demon-level, stronger than those that had invaded the city before.
"Don't think you're at the peak of power. If you anger that Great One, you will all be buried here forever!"
The leading Subterranean was full of rage, showing no fear even when facing the powerful King.
Mind Control!
King didn't want to waste words with them and directly controlled the Subterranean's mind.
"Where is this?"
"The... Subterranean World..."
"Who is your leader?"
"The... the Great One is Earth's..."
Bang!
Before the Subterranean could finish its sentence, its face suddenly showed a look of agony, and then its entire body exploded into pieces.
"Hmph! A clever trick."
Psychic Storm!
King was infuriated, he didn't expect the opponent to dare play such a trick right under his nose.
Woo woo woo!
Countless blue streaks of light formed a hurricane, instantly covering a hundred-mile radius and continuously sweeping through everything in the vicinity.
"If you don't come out, I will completely destroy this place." King's face was dark.
He couldn't confirm the opponent's location, which proved the enemy's hiding ability was extremely sophisticated.
However, if he destroyed this entire Subterranean world and left no creature alive, he didn't believe the mastermind behind it wouldn't get anxious.
"Still not coming out? Then I'll just blast right through this place."
Fourth Layer Liberation! Meteor Strike!
