The barrage of artillery fire, like a dense meteor shower, completely engulfed the Rain Dragon's massive body.
Explosions of black-red Cursed Energy occurred one after another; every impact made the earth tremble violently. Splattered gravel and dragon scales, mixed with purple blood, bloomed into tragic flowers in the mud.
Although the Rain Dragon's blue-black scales had an innate immunity advantage against Cursed Technique attacks, they ultimately could not withstand such violent and dense artillery fire.
The crisp sound of shattering scales rose and fell in succession. Wounds deep enough to reveal bone covered its entire body, its dragon wings had long been blown to tatters, and it had even exhausted the strength to support flight.
Yet, it still hunched its body tightly, shielding the Thunder Beast's only remaining head beneath it. Two lines of crimson blood tears seeped from its golden vertical pupils, sliding down its dragon face and blending into the torrential rain and mud.
It could have used the advantage of its Domain to maneuver, but it did not. The Thunder Beast's head was its brother's last remaining trace, an obsession it would protect even at the cost of its life.
Amidst the roar of artillery fire, the Rain Dragon's body gradually went limp, its consciousness like a candle in the wind, about to be extinguished.
And in the Thunder Beast's head, shielded under the dragon's claw, a trace of determination and grief flashed through its remaining azure pupil. It felt its brother's aura rapidly dissipating, felt that the body protecting it was already on the verge of shattering.
"Brother... let us become one... this is our last chance!"
A weak yet firm intent transformed into a final wave of Cursed Energy, erupting from the Thunder Beast's head.
Rin raised an eyebrow, a trace of surprise flashing in his Crimson Sharingan.
He clearly sensed that the two Cursed Spirits, which had been on the verge of death, suddenly saw their auras climb crazily. The originally scattered Cursed Energy gathered like a hundred rivers returning to the sea, forming a terrifying power far exceeding what it had been before, quietly surging amidst the ashes of the artillery fire.
"Not over yet?" Rin stopped his artillery attack, raised a hand to wipe off the mud splattered on his face, and stared sharply at the smoke and dust filling the air ahead.
The next second, a thunderous roar that shook the heavens and earth suddenly erupted from within the smoke and dust!
The torrential rain seemed to be instantly ignited; countless azure lightning bolts converged from the curtain of rain, crazily pouring toward the direction of the dragon corpse.
The originally limp Rain Dragon body suddenly tossed and turned. The blue-black dragon body was entwined with dense lightning, and the Thunder Beast's black lightning Cursed Seal seemed to come alive, rapidly spreading across the dragon scales and covering the entire dragon body.
The lightning and dragon body completely fused; the originally incomplete dragon body was reconstructed by lightning, transforming into a pair of huge thunder wings shimmering with lightning.
The tips of the dragon claws were surrounded by crackling electrical arcs, becoming sharper. The golden vertical pupils were intertwined with the azure of lightning, exuding a pressure that was both sorrowful and violent.
The two figures completely merged into one—a Special Grade Cursed Spirit possessing both the hardness of a dragon body and the swiftness of lightning.
The Thunder Dragon was reborn from the fire amidst the torrential rain and lightning!
It flapped its thunder wings, hovering in the air. The lightning and rain around its body intertwined, forming an energy field that distorted space.
The originally incomplete Domain was instantly completed. The might of the "Thunder Water Domain" surged several times higher than before. The rain within the Domain transformed into lightning rain with a paralyzing effect, while the accumulated water on the ground turned into lightning vortexes capable of devouring Cursed Energy.
"Human... you have completely enraged us!"
The Thunder Dragon's voice sounded like a thunderclap, an interweaving of the Thunder Beast's sharpness and the Rain Dragon's deep tone, carrying world-destroying fury.
Its pupils, intertwined with gold and azure, locked tightly onto Rin. With a flap of its thunder wings, it transformed into a stream of light wrapped in lightning, charging fiercely toward Rin.
Its dragon claws carried the might of a sure-hit, while the lightning transformed into the sharpest blade, vowing to tear the human before it—who destroyed its brother and trampled upon what it protected—into a thousand pieces!
Rin stood where he was, watching the charging Thunder Dragon. There was not a shred of fear in his Crimson Sharingan; instead, a more burning fighting spirit ignited.
He could feel that this fused Cursed Spirit's strength had already reached the peak of Special Grade, even faintly touching a higher level.
"That's more like it."
Rin curled his lips into an excited smile, black-red Cursed Energy surging crazily around him: "This kind of battle is what I have been pursuing!"
The Thunder Dragon's roar shook the heavens and earth, destruction surging in its gold and azure intertwined pupils.
It flapped its huge wings covered in lightning, the torrential rain and lightning around it suddenly turning violent, and the Cursed Energy of the Domain swept out like a tsunami: "Domain Expansion—East Sea Rain Dragon Palace!"
The moment the words fell, the surrounding battlefield completely disappeared.
The scorched earth and gravel beneath Rin's feet faded away, replaced by an endless, surging lake surface. The black lake water, like boiling ink, churned with waves several meters high. The waves were mixed with sharp ice shards and crackling lightning, crashing crazily toward him.
The sky was completely obscured by thick dark clouds. The torrential rain poured down like a river from the heavens, the dense rain threads carrying paralyzing Cursed Energy, delivering a bone-chilling pain when they struck his body.
In the distant sky, rolling thunder shuttled through the clouds, and streaks of pale lightning tore through the darkness, illuminating this boundless water prison.
This was the Thunder Dragon's Domain, the East Sea Rain Dragon Palace.
Within the Domain, it was the Dragon King who controlled wind, rain, thunder, and lightning. Both the lake water and the lightning were its weapons, and the sure-hit effect was like a maggot attached to the bone—no matter where Rin was, he could feel several attack trajectories locked tightly onto him, inescapable.
The huge waves, wrapped in lightning, crashed down with a boom, yet Rin still stood where he was, his Crimson Sharingan calmly scanning this water Domain, not a trace of panic on his face.
Facing the Domain of a peak Special Grade Cursed Spirit, not only was he not afraid, but he revealed an excited smile instead.
"A Domain? Perfect, my Domain hasn't been opened for a long time either."
Rin slowly raised his right hand, making Finger Seals with one hand. The black-red Cursed Energy at his fingertips spread like a prairie fire, and the air around him twisted violently due to the violent Cursed Energy.
He softly spat out five words, his voice not loud but carrying a majesty that shook the heavens and earth: "Domain Expansion, War World."
BOOM!!!
Black-red Cursed Energy erupted instantly, like a volcano breaking free from its shackles, spreading toward every corner of the East Sea Rain Dragon Palace.
The originally surging black lake surface, under the impact of War World's Cursed Energy, instantly froze and shattered.
The black lake water turned into countless fragments, torn and crushed by invisible forces, replaced by an endless steel plain.
On the plain, dense artillery, Tanks, and missile launchers rose from the ground, their muzzles all aimed at the Thunder Dragon in the sky. Black-red Cursed Energy gathered in the gun barrels, shimmering with a deadly luster.
The dark clouds and torrential rain in the sky were forcibly dispelled by the aura of War World, replaced by a dark red sky. Beneath the sky, fleets composed of countless fighter jets and bombers circled and soared, the Cursed Energy bombs mounted under their wings shimmering with dangerous light.
The Cursed Energy of the two Domains collided and tore at each other violently in mid-air, forming a clearly defined boundary.
The lake water and lightning of the East Sea Rain Dragon Palace attempted to erode the steel plain of War World, but were forcibly blocked by the black-red Cursed Energy surging on the plain, turning into hissing white mist.
Meanwhile, the artillery fire and warplanes of War World, wanting to break through the wind and rain barrier of the Rain Dragon Palace, were also repelled time and again by the huge waves and thunder, erupting with deafening roars.
The two completely different Domain rules crushed against each other, the space trembling violently, as if it were about to collapse completely in the next second.
A trace of unbelievable shock flashed in the Thunder Dragon's pupils. It had not expected that this human would actually possess a Domain, and that the scale and power of this Domain were not at all inferior to its own East Sea Rain Dragon Palace!
"Impossible! How could a human possess such a powerful Domain?!"
The Thunder Dragon let out an angry roar, flapping its huge wings and manipulating the power of the East Sea Rain Dragon Palace to launch a fierce attack.
Countless lightning bolts struck down from the clouds, transforming into huge Thunder Dragons that dove toward the steel plain. Beneath the lake surface, several dragon-shaped phantoms condensed from lake water broke out of the water, carrying cold killing intent as they attacked Rin.
