Mysterious Fusion Begins

The lava lake of Red Flame Volcano had been boiling for seven years. Lin Tian sat cross-legged on the obsidian at the crater's edge, letting scorching sulfur steam brush past his face, eyes tightly shut, yet his consciousness spread like a spider's web through every inch of the volcano's interior. In seven years, he had lost count of how many times he had witnessed magma erupt, how many times he had felt the earth tremble—that violent power, wrapped in destruction and rebirth, had long been etched into the depths of his soul.

"Boom—"

The ground beneath him suddenly shook violently. A hundred-meter pillar of magma surged from the center of the lava lake, crimson magma bursting like fireworks, hot debris mixed with sparks flying everywhere. An ordinary Saint Domain expert would have fled long ago, but Lin Tian sat unmoving, the golden-red flames around his body automatically forming a barrier that turned the flying debris to dust. His consciousness climbed along the magma pillar, sensing the power surging from the earth's core—first the oppressive compression of rock layers, then the instant burst as it broke through the crust, and finally the violent expansion of energy release.

"So this is the essence of 'Explosion'?" Lin Tian murmured to himself. Seven years ago, when he first arrived, he only thought the Explosion Mystery was about the violent detonation of flames. But after seven years, he gradually understood that the true 'Explosion' lay in the connection between buildup and release, in that instant when energy went from compression to eruption.

He tried to mobilize his divine power, imitating the rhythm of magma eruption. A flame the size of a walnut condensed in his palm. The flame first contracted inward, its surface light gradually dimming as if compressed by an invisible force. Just as the flame was about to extinguish, Lin Tian suddenly released his hold on the energy—a soft "hiss" sounded, and the flame did not explode as expected, but instead dissipated into a wisp of green smoke.

"Still lacking," Lin Tian shook his head with a wry smile. Over these seven years, he had failed like this tens of thousands of times. Sometimes the flame scattered too much, its power no more than a spark; sometimes it was over-compressed, causing the energy to annihilate. He knew the problem lay in grasping the 'critical point'—just like before a volcanic eruption, the pressure accumulated by magma underground must exactly break through the crust's restraint; a bit more and it erupts prematurely, a bit less and it lacks the force to surge.

Another volcanic eruption came. This time, Lin Tian did not sit and observe, but leaped into the air above the lava lake. Scorching magma droplets splashed against his flame barrier, making a sizzling sound. Facing the towering magma pillar, he sank his consciousness completely into it, meticulously capturing every detail of that power from suppression to eruption: the crisp crack of rock layers breaking, the violent collision of magma molecules, the ripples of energy wave diffusion...

"Right now!"

Just as the magma pillar reached its peak and was about to begin falling, Lin Tian suddenly raised his hand, condensing flame in his palm once more. This time, he did not deliberately compress the energy, but let the flame flow on its own according to the rhythm of magma eruption. The flame first rolled and surged like magma, as if gathering power; then, an invisible 'tension' generated inside the flame, like the crust's restraint on magma; finally, when that tension reached its limit, Lin Tian lightly shouted: "Explode!"

"Boom!"

A basketball-sized ball of flame suddenly detonated. A golden shockwave spread in a ring, and wherever it passed, the flying magma was forcibly shaken into dust. Even more remarkably, the explosive energy did not scatter wastefully, but concentrated its impact in one direction like a volcanic eruption, blasting a large crater into the distant rock wall.

Lin Tian hovered in the air, looking at that crater, a flash of ecstasy in his eyes: "It worked!" He had finally grasped the essence of the Explosion Mystery—it wasn't about the amount of energy, but about mastering the rhythm of 'buildup-burst-direction', just like how a volcano could precisely shoot the power of the earth's core into the sky, rather than exploding aimlessly.

Over the next three years, Lin Tian began to skillfully use the Explosion Mystery. He could condense flame into a single point on his fingertip, which would explode on contact, its power comparable to a full-force strike from a Saint Domain peak expert. He could also attach flame to his body like magma, suddenly detonating it when an enemy approached, forming a defensive shockwave. But he was not satisfied with this. Leo I's words always echoed in his ears: "The true essence of Mysteries lies in fusion. No matter how strong a single Mystery is, it is hard to match the wondrous uses of fusion."

He began to attempt fusing the Explosion Mystery with the Fire Element Mystery.

The Fire Element Mystery emphasized the exquisite control of flames, allowing them to move like an extension of one's arm. The Explosion Mystery, on the other hand, pursued instantaneous explosive power, emphasizing destruction and impact. One was soft, the other hard; one was delicate, the other violent—they seemed as incompatible as fire and water. The initial fusion attempts were disastrous: sometimes the flame had just taken shape when it prematurely exploded due to an inability to control the Explosion Mystery, leaving Lin Tian covered in soot; other times, over-suppressing the Explosion Mystery caused the flame to lose its explosive edge, becoming weak and powerless.

"Perhaps I've been looking for the wrong direction of fusion," Lin Tian sat at the crater's edge, gazing at the rolling lava lake below in contemplation. He recalled the scene he had observed seven years ago: when magma was underground, it could both flow like water (the agility of the element) and accumulate enough power to break through the crust (the buildup of Explosion). Wasn't this a state where the two Mysteries coexisted?

He sank his consciousness again, sensing the energy flow inside the volcano. Sure enough, deep in the earth's core, the magma both maintained the fluidity of the element and contained the potential for explosion. The two were not opposites, but interdependent—precisely because magma could flow and gather like an element, it could accumulate enough pressure in a confined space; and precisely because it had explosive potential, the flow of magma carried a sharp, unstoppable momentum.

"So that's it!" Lin Tian suddenly saw the light. He had previously tried to 'forcefully coordinate' the two Mysteries, but had overlooked that they could, like magma, conceal explosion within flow, and carry agility within explosion.

Just then, Red Flame Volcano experienced a once-in-a-century massive eruption. The entire mountain trembled violently, as if trying to tear itself from the earth. The lava lake completely boiled over, turning into a red ocean. Several magma pillars shot straight into the sky, dyeing the heavens a golden-red. This time, Lin Tian did not dodge, but completely merged his body into the magma, letting the scorching energy wash over him.

He tried to operate both Mysteries simultaneously: letting the flame flow over his body like magma (Fire Element), while imbuing every flame molecule with explosive potential (Explosion). At first, the two forces still clashed, the flame sometimes stiff as rock, sometimes scattered as water. But as the volcanic eruption intensified, Lin Tian's consciousness became more and more synchronized with the volcano's rhythm. He gradually found the point of harmony between the two Mysteries—just like magma flowing through rock crevices, it both maintained flexible form and accumulated explosive force through constant compression. Flow was the prelude to explosion; explosion was the destination of flow.

"Fuse!"

Lin Tian let out a low shout. The flames on his body suddenly underwent a wondrous change. The golden flames were no longer simply flowing or exploding, but displayed a state of 'aliveness': they could wrap around flying debris like flowing water, then suddenly explode on contact, grinding the debris to powder; they could also condense into chains to trap a target, each link of the chain hiding explosive power, needing only a thought to detonate in a chain reaction.

When the volcanic eruption reached its peak, Lin Tian shot into the sky, the flames around him transforming into a golden fire dragon. The dragon's scales shimmered with a metallic luster as they flowed (the condensation of Fire Element), while its open maw brewed a destructive orb of light (the buildup of Explosion Mystery). He spat the orb at a distant, uninhabited mountain peak. The orb did not explode immediately, but burrowed into the mountain's interior like a living thing. Then, with a thunderous "boom," the entire peak collapsed from within. Amidst the billowing dust, only a massive crater remained.

"The Fire Element and the Explosion Mystery... they've finally begun to fuse." Lin Tian landed on the ground, feeling the new power flowing within him, a smile spreading across his lips. This fusion was not a simple stacking, but had birthed a completely new ability—he could 'hide' the power of explosion within the flow of the element, striking unexpectedly, making it impossible to guard against.
