I became a god by treasure hunting after arriving 500 years early-Chapter 592 - 432 New Myth and Old Myth

Chapter 592: Chapter 432 New Myth and Old Myth

Grotto Heaven, located about 150,000 meters beneath the surface of the Earth.

There is a babbling flow of magma from underground, like tidal waves, surging and making a “whoosh” noise.

The rocky walls gently vibrate, sometimes soft, sometimes contracting.

Lu Yuan, with his eyes closed, carefully discerns and feels an overwhelming power, almost like the thundering of drums. However, this sound is inaudible to ordinary people; it is a form of Mind wave, with very low frequency, pulsing only once per hour.

Thump! Thump!

This time he truly felt a deep shock; this was no ordinary Grotto Heaven… it was the heart of a living creature!

The underground tunnel they had just traversed was, in fact, merely a…blood vessel!

That is to say, the rail train traveled thousands of kilometers along the blood vessel before entering the heart.

“This really is a corpse…”

“An Ancient Giant Demon’s corpse?” he exclaimed in genuine astonishment.

“Great Commander, stop daydreaming, we’ve arrived!”

Lu Yuan quickly snapped back to reality, suppressing the doubts in his mind. The People of the Underworld might know some information, or perhaps, they merely live their simple lives without much thought…

This is not a place for discussions; it can wait until we return to headquarters.

“Dear guests, we have entered Grotto Heaven, please disembark.”

Dadao Gang performed a greeting in front of the train door.

Lu Yuan followed everyone and got off the train.

Before them was a huge train station, with tracks extending in all directions, connecting the entire “Grotto Heaven”.

It is evident that the high-speed train technology here is highly developed.

There are also various decorative items shaped like gears, showing the deep influence of Gear Civilization on this place.

The air is a bit hot, probably around 40 degrees Celsius, since right below is the bright red magma—well, whether it’s actually magma is still unknown.

At the edge of the “Grotto Heaven” is a strange layer of transparent material akin to jelly, slowly moving and gradually expanding the volume of “Grotto Heaven”.

In the sky, there are several “Suns”, about as big as fists, very bright, illuminating the entire underground—a kind of Extraordinary Artifact called “Sun Stone”.

Superior Level, quite rare.

The leaders of the 12 races of the Underground Alliance have already been patiently waiting. The honor guards are playing peculiar instruments, using a unique ritual to welcome the human diplomatic team.

The young females of the Dark Steel Civilization dance gracefully—they really resemble the Green Grass girls, except their skin is a bit darker, still quite aligned with human aesthetics here.

“Human friends, hello!”

“I am the Chairman of the Alliance, Tie Kui. Here, I sincerely welcome you.” The leader, a large-bearded creature, took off his hat and introduced each of the race leaders.

Dark Steel Civilization, Cross-eyed People, Minotaurs, lizard men, Snake-men, Cave People…well, this reminded him of some “dungeon computer games” from Earth.

These creatures with heads of bulls and horses stared at humans, grimacing and greeting.

“Hello, friends.”

“I am the Great Commander of Human Civilization, Lu Yuan.”

Lu Yuan slightly bowed: “Since the patient’s life is at stake, every second is precious… hence, let’s not make the reception too complicated, just take us directly to the patient.”

“If it’s cured, we can celebrate later.”

“And if not, please do not blame us.”

His statement was quite reasonable, and after a moment of hesitation, the Underground Alliance agreed with Lu Yuan’s suggestion.

Thus, the train started again, carrying everyone and eight Mecha Puppets, heading towards the central part of Grotto Heaven.

There, there’s a huge park, about the size of 10 sports fields.

At the heart of the park, an altar made of white jade stone is studded with countless gears, forming a complex and vigorous whole. The gears are spaced perfectly, displaying a complex and exquisite artistic charm.

Of course, that’s not the main point.

Beneath the altar, there’s an even smaller “Grotto Heaven”!

The Ancient Insect, it hides within this small cave.

“The time ratio in the small cave is one percent of the outside world, it has been suffering there for a long time,” Chairman Tie Kui sighed.

“How did it get injured?” Lu Yuan asked.

“It might be… a disaster from a previous Epoch, it was already injured before we met it. As for what exactly happened, it has always refused to say.”

That also matches people’s reasoning.

“I shall awaken it now… every time it wakes up, it consumes some Life Energy, I am worried…”

The Underground Alliance had to prepare for the worst. They were willing to pay the medical expenses, but no family member would want to see their loved one die on the operating table.

“Mr. Tie Kui, even if it’s not cured, providing it with some Life Energy is still something we can do,” Lu Yuan patted the “Greedy Demon God” beside him, “Keeping it alive a bit longer is a piece of cake.”

“This robot is called ‘Greedy Demon God’, a healing robot I specifically developed, its Level is nearly Immortal Level.”

“As long as you continuously provide Spirit Essence, even if only the head is left and all other organs are destroyed, it can still prolong your life, until the Spirit Essence is completely depleted.”

Suddenly, a lush green vine extended out, accompanied by rich Life Essence.

In the light, it even formed a faint rainbow.
