The volcano space is vast, and there are quite a few fire element veins inside, but in front of Udi, who revealed his fifty-meter-long Black Dragon true form, it’s all insignificant.

In just a short moment, this miniature fire element vein inside the volcano was collected by the dragon’s mouth till nearly depleted.

"The spatial bags are all full."

At one point, Udi stopped.

Besides bringing a few spatial bags filled with treasures for this abyss expedition, he also brought a heap of empty spatial bags.

Though there were many, they were basically a few cubic meters in size, with some being a dozen cubic meters.

After a frenzy of mining, all these spatial bags were filled to the brim.

"Looks like it’s time to learn a spatial storage spell," Udi mused to himself.

Glancing at the remaining scattered fire element ores, Udi ignored them and continued to swim towards the depths of the magma.

The dragon’s intuition told him that there were even more precious treasures deep within the volcano.

The fire element vein on the periphery was only of inferior quality, a substantial fortune for a typical adult dragon, but just ordinary for Udi, who controls the entire Black Wing Nest, with his territory spanning millions of square kilometers.

The excitement he showed was merely because he felt pleased by the windfall.

It’s like finding ten bucks while walking—it’s not much, but it’s delightful.

This active volcano stands a thousand feet tall, but its actual depth far exceeds a thousand feet; a thousand feet is merely the height protruding from the surface, while the underground foundation depth makes up the volcano’s main body.

The Black-scaled Giant Beast swam downwards like an arrow, occasionally encountering fire element crystals floating in the magma, which it picked up casually.

Under the same quality, the value of fire element crystals is higher than that of fire element ores—the former is mainly used for cultivation and as an energy source, while the latter serves as base materials for making equipment, buildings, arrays, and more.

"The abyss is truly abundant."

Udi couldn’t help but marvel as he delved into the magma and casually picked up hundreds of inferior, subordinate-level fire element crystals.

If active volcanoes with such resources littered the abyss, then merely picking up these treasures every day would make one amass wealth comparable to that which the Black Dragon Maiden has accumulated over a century within a month.

Just as Udi’s greed and desire for the abundant materials of the abyss arose, a covert ripple attempted to approach him from below.

A sneak attack?

Udi pretended not to notice and continued diving deeper.

Eventually, with a whoosh, a crimson elongated figure that almost blended into the magma lunged to bite Udi.

Clang!

At the crucial moment, a massive, pitch-black dragon claw directly grasped the crimson figure’s head.

It was then Udi could clearly see what creature was attacking him.

A fire python over twenty meters long, its aura fluctuations reaching advanced levels.

The fire python’s giant head struggled frantically within the pitch-black dragon claw, with frightening golden-red flames rising from its body attempting to scorch and burn the pitch-black dragon claw.

Unfortunately, the golden-red flames, with temperatures reaching at least several thousand degrees, merely made the pitch-black dragon scales more lustrous.

"Trying to polish me, huh?" Udi sneered, and with a slight squeeze of the massive pitch-black dragon claw, the fire python’s head shattered.

Ignoring the fire python’s twitching and struggling body, Udi hooked it with his Dragon Finger and filleted it to eat like a spicy strip.

*Burp~*

Now, he was truly full.

Having previously consumed at least a hundred beast demon creatures, and now a high-level fire python from the abyss, even Udi felt a bit overstuffed.

"Could this fire python be the master of this active volcano?" Udi speculated in his mind.

Upon first discovering the fire element vein, Udi had suspected that there was probably some powerful fire element creature within this volcano.

Such an environment, even if it doesn’t spontaneously breed fire element creatures, would attract and gather them to occupy it.

The beast demon creatures encountered outside the volcano should have been drawn in by the rich fire element environment here, so there was no reason for there not to be any life within the part of the volcano where the fire element is even more concentrated.

"No, that fire python is just a very ordinary high-level creature, not enough to occupy such a valuable volcanic site."

Thinking of this, Udi halted his descent and muttered a magic spell, releasing a Second Ring Eye of Investigation spell; the invisible eye of investigation continued to penetrate deeper into the volcano while Udi transformed into dragon-man form and found a random cave in the lava wall to wait for the spell’s results.

The verification proved that the entity that attacked him was indeed not the volcano’s master.

Under the observation of the eye of investigation, there were still multiple fire pythons of similar size to the previous one lying dormant in the magma seven to eight thousand meters down.

The eye of investigation kept diving, twelve thousand meters, fifteen thousand meters, twenty thousand meters.

Within the nearly golden magma, two massive golden-red magma eyes suddenly opened, gazing at the invisible eye of investigation.

In an instant, the Second Ring Eye of Investigation spell shattered and vanished.

Before the eye of investigation disappeared, the last frame of the scene was transmitted to Udi’s mind.

It was a terrifying fire python over a hundred meters long, with a massive snake body and spikes of golden-red crystals on its back.

"This big guy is probably the true master of this volcano." Udi grinned, showing no sign of fear.

Judging by the aura the other creature emitted, this massive fire python seemed not to be a Legendary Creature.

But neither was it an ordinary Top-Level Creature.

In terms of aura intensity, it was somewhat comparable to the full-force outbreak of the Black Dragon Maiden during a battle with the Wild Dwarves over a decade ago.
