This was an underground world with no visible end.
Su Zhe stared at the scene before him, stunned.
How far had he walked?
Ten thousand meters, a hundred thousand meters, or even farther?
In any case, this was undoubtedly the deepest part of the Lava Secret Realm!
At the top of this underground space hung a gigantic luminous body, like a star, illuminating the entire underground world. As far as the eye could see, lava flowed everywhere, and vast quantities of bright golden lava eventually converged into a sea of magma at the center.
The sea of magma stretched out endlessly, its far edge nowhere in sight.
"Xiao Yu, what... is that?"
Su Zhe murmured.
"Master, according to information gathered from the Virtual Universe, that gigantic luminous body may be a Fire Marrow Heart," Xiao Yu replied.
"The Fire Marrow Heart is even rarer than Fire Marrow Crystals. It's sold for Universe Coins, and even Universe Level fighters usually have difficulty obtaining one. It's a treasure suited to Domain Lords."
"The Fire Marrow Heart is sold by the Black Dragon Mountain Branch of both the Virtual Universe Company and the Universe Mercenary Alliance. Now it seems the Lava Secret Realm must be where it comes from."
Using the Virtual Universe, Xiao Yu quickly gathered a wealth of information and eventually determined the origin of the gigantic luminous body.
Su Zhe nodded slightly and looked toward it. Although it was extremely far away, he could still sense an intense aura of the Origin Law of Fire.
If he could dig that thing out and devour it, the boost it would bring was unimaginable.
However...
Su Zhe looked at the Lava Monsters that had entered this underground space alongside him.
There was probably more than one passage leading here.
In the distance, Su Zhe saw the figures of more Lava Monsters appearing. It was very likely that all the Lava Monster lairs in the Lava Secret Realm led to this underground space.
There was one thing Su Zhe was curious about.
What had these Lava Monsters come here to do?
Su Zhe watched them make their way toward the sea of magma in the center of the underground space, seemingly preparing to step inside.
The sea of crimson-gold magma churned, radiating terrifying heat. Su Zhe had no doubt that its temperature rivaled that of a star.
Even Universe Level fighters probably wouldn't dare enter it recklessly without protection.
Su Zhe watched as the few ninth-tier Star Level Lava Monsters that had arrived in this underground space with him leaped into the boiling golden magma without the slightest hesitation. Their movements were filled with a reverence almost like pilgrims'.
"Splash!"
The golden magma was unexpectedly not viscous. Instead, it flowed as smoothly as water, and when the Lava Monster fell into it, golden "spray" splashed up.
As the Lava Monsters stepped into the sea of magma, the rocky armor covering their bodies was quickly enveloped by it.
To Su Zhe's astonishment, their rocky armor didn't melt in the intense heat. Instead, like young beasts returning to their Matriarch, the Lava Monsters curled up into balls beneath the magma's embrace.
"Are they... absorbing energy?"
Su Zhe looked at the Lava Monsters. The energy in this sea of magma was far purer than that found outside, nearly on par with Fire Marrow Crystals. It was practically a sacred ground for cultivating the laws of fire.
The Lava Monsters absorbed the magma continuously, drawing it into their bodies.
"Wait... they're evolving?!"
"Are the Lava Monsters using this method to evolve to Universe Level?"
Su Zhe found it hard to believe.
Did that mean that any Lava Monster that reached the ninth tier of Star Level could definitely advance to Universe Level?
What exactly was this magma, to have such a powerful effect?
"Xiao Yu, what are these golden liquids? Have you found anything?"
Su Zhe hurriedly asked.
"No, Master."
After checking the information in the Virtual Universe, Xiao Yu replied, "Although there are thousands, even tens of thousands, of similar liquids in the Virtual Universe, I haven't found anything exactly like this."
"Their effects vary to some extent."
"There are treasures that can directly turn a ninth-tier Star Level fighter into a Universe Level fighter, but they're far too expensive. They clearly don't match the properties of this magma, and the Fire Marrow Heart doesn't have that effect either."
Xiao Yu spoke quickly.
Su Zhe furrowed his brow.
Could this golden magma be a treasure too?
Su Zhe went right up to the sea of magma and took some golden magma.
The golden magma was extremely hot, but when it touched Su Zhe's Camouflage as a Lava Monster, it didn't feel scorching at all. Instead, it felt remarkably gentle.
Was this a cultivation treasure exclusive to Lava Monsters?
Puzzled, Su Zhe tried to absorb the golden magma.
Once it entered his body, the golden magma transformed into pure fire-attributed energy. It continuously strengthened Su Zhe's body while attempting to guide the Genetic Origin Energy within him to break through to Universe Level.
Unfortunately, there wasn't enough energy, so Su Zhe couldn't complete the breakthrough.
Su Zhe needed more energy to break through than an ordinary Lava Monster did.
Devouring the golden magma didn't earn Su Zhe any Devour Points either.
It had been the same when he devoured the Fire Marrow Crystals earlier. The Devour Points on his panel seemed to increase only when he devoured living beings.
"Master, there's also a powerful high-energy reaction at the center of the sea of magma," Xiao Yu said.
"All right."
Su Zhe nodded. He was planning to enter the depths of the sea of magma too, but he would wait a little longer.
He'd wait and see whether the Lava Monsters completed their evolution.
What if something went wrong?
He waited several days.
Su Zhe sat bored on the shore of the sea of magma, and at last one of the Lava Monsters completed its evolution!
"Boom!"
A powerful aura erupted from the sea of magma. With the help of the golden magma, the ninth-tier Star Level Lava Monster broke through to Universe Level!
After breaking through to Universe Level, the Lava Monster headed for shore. As it passed Su Zhe, it stopped curiously, seeming to wonder why he hadn't entered the sea of magma.
Su Zhe looked at it too and cautiously approached. Then—
"Bang!"
His domain unfolded. With Su Zhe's current strength, killing a fierce beast that had only recently reached Universe Level in a single blow at such close range was easy.
[Devoured a Universe Level Tier 1 fierce beast. Gained 6,553,600 Devour Points.]
[Devour Point conversion: 655 Devour Coins.]
He devoured the Lava Monster without a fuss, and the fight hadn't caused much of a disturbance.
Su Zhe looked toward the sea of magma. Now he could consider venturing into its depths.
And how was he going to obtain the Fire Marrow Heart above the sea of magma?
That was another problem.
