Golden light erupted all around Zhongli, the divine attire's runes flowing like stars. Countless stone blades rose from the sea's surface, forming a forest of sharp edges that slashed toward Osial's tentacles.
Sparks flew upon impact, rock shards and black blood splattering with a piercing "sizzle," the sound of stone being corroded by venom.
When the giant Stone Spear pierced the night sky, it carried a heavy pressure, its tip glowing with a golden light capable of piercing the darkness, and it stabbed viciously into Osial's head!
Black blood erupted like a fountain, dyeing the entire sea surface inky black, yet it was catalyzed by the Abyssal power in an instant.
Osial's wound healed at a speed visible to the naked eye, even growing tougher, black-purple scales.
Venti's wings unfurled to their fullest extent, their emerald green light exceptionally dazzling in the night. Three hurricanes carrying thunderstorms formed simultaneously, thunder and lightning crackling within the wind pillars like three furious azure dragons, smashing violently into Osial's tentacles.
"Boom!"
The deafening explosion shook heaven and earth, the blinding light from the thunder's burst making Lumine unable to open her eyes. The black venom torn apart by the hurricanes fell like torrential rain, corroding the sea surface into dense bubbles.
But the tentacle paused for only half a second before it tore through the wind pillars with brute force, continuing its devastating assault on the Dual Gods.
The Anemo-Geo Barrier erected by the two gods was the only line of defense at this moment.
The emerald hurricane and golden rock wall intertwined, blocking the impact of the towering waves, yet they cracked with a mournful "creak, creak" with every collision, as if they would completely collapse the next second.
The air distorted and trembled under this force, and the embankments of Liyue Harbor in the distance continuously shed stone fragments, while even the earth itself shook slightly.
The sea surface beneath her feet was even more turbulent, making Lumine feel as if she would be sucked into this vortex of destruction at any moment.
Watching all this, Lumine felt herself to be as insignificant as a grain of sand in the sea.
Her fingertips trembled slightly. Her limbs had already gone numb from shock and instinctive fear, and even the strength to raise her hand seemed to have been drained away.
This was not a battlefield she could participate in!
It was not even a realm she could approach!
When she fought Yunqin earlier, she thought she had already witnessed powerful force, but facing the duel between a god and a god now, she finally understood what true "heaven and earth collapsing" meant.
That pure, destructive power was more oppressive than the darkest depths of the Abyss, making her instinctually want to retreat!
Yet, the moment she took a step back, Lumine's feet felt nailed to the sea's surface, her gaze locked onto the unconscious Yunqin and Hydro Qin in the distance, forcing her to halt abruptly.
Seeing Yunqin and Hydro Qin unconscious on the sea, seeing the Three Adepti still trapped in the illusion, and seeing the Millelith and Favonius Knights standing frozen on the shore, who could be caught in the battle's crossfire at any moment, a powerful sense of responsibility surged in her heart.
"I have to get them to safety!" Lumine gritted her teeth, leaving a red mark on her lower lip.
She held Yunqin tighter in her arms, then carefully leaned over to scoop up Hydro Qin from her side, pulling them both close to her chest.
Their two warm bodies weighed slightly on her arms, yet she dared not relax for a moment.
She looked ahead, where the Three Adepti's figures swayed in the raging wind, at risk of being struck by Osial's tentacles.
Lumine took a deep breath, her Anemo energy erupting as she unfurled her teal Wind Glider, slowly taking flight with the two in her arms.
Afterward, she made several more trips, carrying the Three Adepti, the Millelith on the shore, and the Favonius Knights one by one to the Liyue Harbor shelter.
This was the highest and most fortified building in Liyue Harbor, constructed from thick stone, enough to withstand giant waves and impacts.
"Hold on!" Lumine whispered to the unconscious Yunqin in her arms, sweat trickling down her cheeks and soaking her collar, her arms trembling slightly from the prolonged weight. "Zhongli and Venti are fighting outside. I will protect you, protect Liyue Harbor, and not let anyone get hurt!"
She returned to the edge of the battlefield one last time, watching the Dual Gods fight fiercely against Osial, watching the continuously rising giant waves and exploding lightning, her heart filled with anxiety yet unwavering determination.
She could not back down. Behind her were countless lives, the people she wanted to protect.
Lumine turned and flew away, settling the last Favonius Knight before forcefully shutting the heavy Stone Gate.
The Stone Gate let out a loud "thud," blocking out most of the rumbling noise from outside.
Leaning against the cold Stone Gate, she spoke softly to the unconscious people inside: "Rest assured, two Gods are guarding the outside. We will be fine."
Outside the gate, the fierce battle between the Dual Gods and the god continued. The rumbling shook the earth, and the black seawater continuously assaulted the harbor's embankment, as if trying to tear Liyue Harbor apart.
The Anemo-Geo Barrier, struck by Osial's massive tentacles, was covered in cracks that spread across its surface like a spiderweb.
Crackle... crackle...
The sounds of misery echoed incessantly through the night sky, as if the barrier would shatter completely at any moment.
The golden light of Zhongli's divine attire grew dimmer. Beads of sweat began to seep from his forehead, rolling down his jawline and dripping into the sea to create tiny ripples.
"Barbatos, it seems we must use the Power of the Dual Gods to reforge the seal from that year!"
Venti's wings trembled violently. The emerald Anemo element and Zhongli's Geo element intertwined in the air, forming a spiral torrent of energy that glowed with a breathtaking light.
His face was as pale as paper, and the feathers of his divine attire had lost their luster as his divine power was drained, yet he still forced a smile.
"Understood!"
Before the words even faded, a hurricane several times more massive than before erupted from the ground, like a spinning green giant tower. With a sharp sound that tore through the air, it slammed into Osial's body, tightly binding its dozens of flailing tentacles.
Osial let out an earth-shaking roar. Dark purple venom sprayed madly from its suckers, dripping onto the hurricane's wind wall and emitting a sizzling corrosive sound as the green wind wall was stained a deep ink black.
Venti pushed his divine power to the absolute limit, forcing the hurricane to withstand the venom's corrosion and temporarily pin Osial's body above the sea surface.
"Now!" Venti's voice was hoarse from divine power depletion, and even his breathing had become ragged.
The golden light in Zhongli's eyes flared. His hands swiftly formed a seal, and countless ancient Geo runes emerged from the sea surface, crawling along the hurricane's path like living creatures, spreading toward Osial's head.
That was the Seal of the Geo Archon from the Stone Spear that had suppressed Osial all those years ago. Now, under the combined strength of the Dual Gods, it was once again manifesting the ancient divine might of Teyvat.
Wherever the Geo runes passed, the seawater boiled, and the Abyssal Black Miasma sizzled, forcibly suppressed by the heavy Geo element, making even the air turn scorching hot.
With the Geo Seal about to touch Osial's head, the dawn of victory seemed to be right before their eyes.
