Inside the quiet room, Lin Yan stood upright. Nine crimson-gold divine patterns intertwined across his body, while five fire apertures opened within his limbs and bones, like blazing drills of flame. Most striking of all, his flesh and blood had become translucent, revealing a deep red glass-like skeleton within.
At this moment, a burning sensation spread through his entire body, as if he were engulfed in flames, accompanied by intense pain and itching. The blood generated from his bone marrow condensed into a crimson glow, flowing through his body like molten lava. Heat radiated from him, and an overwhelming strength surged within.
After an unknown period, the transformation brought by the Glass Flame Bone Gu finally came to an end.
Lin Yan's features remained sharp, his physique refined to near perfection. His muscles were tight and well-balanced, his skin glowing with a reddish-jade sheen. When he clenched his fist, the air itself trembled with a faint buzzing sound.
"Immense strength… solid bones. Not inferior to an ordinary Rank 2 Strength Path Gu Master. And Flame Path Gu receive a thirty percent boost in power, regardless of rank."
He silently assessed himself, both surprised and satisfied. As expected of the Huang Family's core Inheritance, his raw physical strength alone was enough to tear apart wild beasts. His body felt as firm as metal, his temperature constantly high, and the heat flowing through his blood seemed impossible to cool.
From this point onward, Lin Yan's physique had completely surpassed that of ordinary Gu Masters. The Flame Demon True Body killer move could now be considered to have entered a deeper stage.
After reading the information within the bookworm, he gained further insight. The Flame Demon True Body was built upon fire patterns, fire apertures, and glass flame bones, allowing for flexible combinations. If defensive Gu were integrated, the transformed Flame Demon would be covered in armor. If offensive Gu were added, it could unleash flames and enhance destructive power.
At Rank 4, the Flame Demon True Body required a Gu known as Fire Heart Gu. Once refined, it would transform the heart, granting extreme resilience within flames, making the user even more formidable.
"Not bad… this way, no matter how I develop my Gu, they can all integrate into the Flame Demon True Body."
Lin Yan's eyes flickered with interest. He then recalled the original core Gu, Borrow Fire Gu. Compared to Glass Flame Bone, it seemed inferior and somewhat redundant.
But he did not dismiss it. The underlying principle of Borrow Fire Gu was different. In his view, it still had potential for development and could possibly be integrated into the Flame Demon True Body, further enhancing the killer move and raising its upper limit.
This was something he would consider later, after gaining a deeper understanding of Flame Path refinement methods.
Next were the two killer moves, Prairie Fire and Flame Extreme Sky Blade. Both had relatively high entry requirements, needing at least Rank 2.
At Rank 2, Prairie Fire could be formed using the Family's improved fire oil, Burning Wind Gu, and any offensive Flame Path Gu, rapidly spreading a sea of flames. Its drawback was a slower activation speed and scattered power.
After reaching Rank 3 and gaining deeper control, there were two development paths.
The first was the route Shen Kuang had taken, mainly using Rank 3 Sparks Gu, Pill Fire Gu, Divide into Two Gu, and Double Effect Gu, allowing Prairie Fire to be unleashed instantly with a simple gesture.
The second path focused on Sparks Gu, Exploding Fireball Gu, Splash Gu, and Burning Wind Gu, expanding the range of the flames.
From this, it was clear that the core of this killer move was the Rank 3 Sparks Gu. Its effect was straightforward—it could generate fire out of nothing.
Normally, Flame Path Gu relied on combustible materials to ignite flames. However, such fire was weak, easy to extinguish, and lacked endurance. Once rain fell or fuel was exhausted, the flames would vanish.
Sparks Gu was different. It could draw upon the free Flame Path dao marks in the surroundings, allowing flames to manifest directly. The fire it produced was stable, powerful, and naturally attracted other Flame Path Gu, enhancing their effects. It could even burn in environments like underwater.
"Wait… Sparks Gu feels familiar."
Lin Yan frowned slightly and quickly recalled information from the original novel. Sparks Gu had a clear origin—it was widely cultivated by a super force in Western Desert, the Fang Family, within a medium-sized resource point known as Sparks Gobi.
They made use of Sparks Gu unique properties to create a large-scale Flame Path environment, allowing them to raise various Flame Path Gu. Every year, they could produce tens of thousands of different Flame Path Gu.
Sparks Gu itself was considered relatively high-end, beginning at Rank 3, though no Rank 6 Immortal Gu variant had appeared so far.
The Huang Family had also established a small Flame Path ecosystem on the central island of Flame Lake. Within it, not only were various Flame Path Gu raised, but many related materials and feeding resources were cultivated as well, such as Flame Marsh Grass, Exploding Grass, and Provoke Fire Bamboo.
However, its scale was far inferior to that of the Fang Family, not even reaching the level of a standard small resource point.
