Douluo Continent: Martial Soul Charcoal Servant, Crimson Lotus Azure Flame!

Moreover, the top-notch simulated environment training room, combined with the high efficiency brought by the unique dual-core meditation with Tan Xiaoshi, and the experience points bonus from battles, made Lin Xia's soul power cultivation speed astonishingly fast.

In just two months, his soul power level soared from level eight to level ten, and he successfully broke through to level ten half a month ago!

This speed is something even Huo Wu, who possesses innate soul power at level eight, cannot match.

Of course, Lin Xia did not forget to study. She used almost all her free time to immerse herself in the library of Blazing Fire Academy, eagerly flipping through a large number of ancient books and documents about soul beasts, martial soul theory, continental history, geography, and even obscure legends.

Lin Xia's browsing through these materials was not aimless; rather, he had a very clear goal: to lay the foundation for Tan Xiaoshi's evolution and to find the most perfect and suitable soul beast!

Tanjiro can independently comprehend the moves Phosphorous Fire and Strange Light, which made Lin Xia keenly realize that Tanjiro may have extraordinary talent in ghost-attribute flames!

So a name gradually became clear—Azure Flame Blade Demon!

That powerful form, wielding two swords, clad in azure flames, and possessing the power of both fire and ghosts!

Therefore, Lin Xia's core goal in browsing through ancient books was to find a rare soul beast that could provide powerful ghost attributes and fire power, or guide Tan Xiaoshi to evolve towards the Azure Flame Blade Ghost!

Finally, through a vast sea of ​​records and rumors, Lin Xia locked onto his target—the Netherfire Beast!

This rare soul beast inhabits the depths of the desert, a place rarely visited by humans and with an extremely harsh environment.

This is precisely the core reason why Lin Xia insisted on coming to the Firestone Desert, despite the safety and convenience of the Academy's Soul Hunting Forest!

One hour later.

The arduous journey across the scorching gravel seemed to have finally come to an end.

After passing over the last massive black stone beam, which resembled the spine of an ancient behemoth, a relatively shady sand valley appeared before them.

The temperature inside the valley was still scorching, but it was much better than the scorching sun outside with no shade.

"It's just ahead!"

Lin Xia lowered her voice and pointed to a huge, tilted black boulder deep in the sand valley.

The area beneath the giant rock formed a deep, shadowy recess, seemingly the only refuge under the scorching desert sun.

Following his directions, everyone held their breath and cautiously approached.

As they drew closer, an even colder and more eerie aura began to emanate, creating a strange clash with the desert's intense heat.

This chill was not cool; rather, it carried a bone-deep, soul-chilling cold.

Finally, dozens of meters away from the giant rock, behind a weathered stone pillar, the group stopped and peered out.

In the shadow of that huge rock, a colossal creature was lying down, resting.

It is enormous, estimated to be over five meters long, and looks like a scorpion magnified several times, but it is far more ferocious and terrifying than a scorpion!

Its shell is not the hard shell of an insect, but is covered with a thick layer of black armor that looks like cooled and solidified lava. The surface of the armor is covered with sharp barbs and jagged protrusions, shimmering with a dark luster.

A thick, powerful tail, covered in the same armor, coiled around its side. The tip of the tail was not a scorpion hook, but a ball of deep purple flame that burned and rolled continuously!

The flames were silent, yet they emitted a chilling and scorching intertwined soul power fluctuation that was the source of that eerie aura!

Its head was hidden in the shadows, with only two points of eerie green light visible—those were its eyes!

It is currently closed, seemingly asleep.

Eight armored, long, segmented legs retracted beneath its body. With each faint breath, it distorted the surrounding air, and tiny, equally deep purple sparks could be vaguely seen escaping from its mouth, nose, and the gaps in its shell, like the breath of the underworld.

This is the Netherfire Beast!

The powerful soul energy emanating from its body, as well as its unique and dangerous Netherworld Flame, all indicated that it was no ordinary being and was precisely Lin Xia's target for this trip!

Lin Xia's gaze was fixed on the sleeping giant beast, her heart pounding with excitement and fighting spirit.

The little servant beside him seemed to sense the fiery power emanating from the Netherfire Beast. The flames on his helmet suddenly shot up and deepened in color. His small body arched slightly, and his fiery eyes blazed with unprecedented solemnity and longing!

After sensing Tan Xiaoshi's fighting spirit, Lin Xia also felt a bit itchy to fight.

Having determined that this Netherfire Beast only had a cultivation level of about five hundred years, he decisively turned to Huo Wushuang and the others who were standing guard beside him and said:

"Senior Wushuang, Sister Huowu, Senior Huolie! You guys stay on the sidelines and support me! Tan Xiaoshi and I want to give it a try and see if we can take it down on our own!"

Lin Xia's voice was resolute, carrying an unquestionable firmness.

"What?!"

Huo Wushuang's thick eyebrows furrowed instantly, and an expression of disbelief appeared on his usually composed face.

"Junior Brother Lin Xia, this is too risky! Fighting a Soul Beast is completely different from fighting a Soul Master. They are wild and untamed, and their attacks are much more ferocious and deadly!"

"A hundred-year-old soul beast is strong enough to threaten a Grand Soul Master, and you're only level ten with no soul rings!"

"just in case......."

Huo Wushuang's words were interrupted by Lin Xia's eyes, which burned with fierce fighting spirit yet were unusually calm.

There was no arrogance in his eyes, only the confidence that came from careful consideration and a strong desire to challenge his own limits!

This made Huo Wushuang's subsequent words of dissuasion stuck in her throat.

"Hey, little junior, you really have wild ideas!"

Huo Wu was also taken aback by this bold suggestion, but her intense interest instantly overwhelmed her worries.

Huo Wu even took an excited step forward, her chestnut ponytail swaying in the hot wind.

"Go! Your sister supports you! If you can't beat them, call us, and we'll make sure they turn into roasted scorpions!"

Huo Wu vigorously waved her little fist, her face full of encouraging anticipation.

This person is clearly someone who loves to stir up trouble!

Looking at his sister's appearance and then at Lin Xia, Huo Wushuang could only sigh helplessly.

"Be extremely careful! If anything seems amiss, immediately retreat. We will provide support as soon as possible!"

Huo Lie opened his mouth, but seeing that Huo Wu had agreed and Huo Wushuang had nodded, and then looking at Lin Xia's expression, he swallowed his words of dissuasion. He just clenched his fists and said in a muffled voice:

"Junior, don't be reckless!"

"rest assured!"

Lin Xia nodded heavily, just about to unleash her fury on the Netherfire Beast while it was sleeping.

And at that very moment—

"Hiss—Roar!!!"

The shadows deep within the sand valley suddenly stirred!

The two points of eerie green light suddenly opened, cold, violent, and filled with the fury of an invaded territory!

The Netherfire Beast's massive body suddenly stood up, its eight long legs, covered in lava-like black armor, stomped hard on the ground, sending sand and dust flying everywhere!

Its scorpion tail, burning with deep purple flames, rose high and then charged directly towards Lin Xia and the others!
