Sea monster.

As Mu Chen and Aria ventured deeper into the unknown, their quest for the Divine Gem led them down a treacherous path. The air was alive with the hum of swordsmen, each one seeking to claim the duo's lives as their own. Mu Chen, undaunted by the daunting task ahead, summoned the fury of the thunder strikes, unleashing a maelstrom of electricity that cut through the swordsmen like a hot knife through butter.

As the last of their assailants fell to the ground, Mu Chen and Aria pressed onward, their footsteps carrying them into the heart of the Lavite Green. The emerald landscape stretched out before them, a soothing balm for their weary souls. Suddenly, a procession of elderly masters emerged from the shadows, their faces etched with the weight of wisdom.

With gentle smiles, the elders welcomed Mu Chen and Aria, ushering them into the grand hall of the Lavite Green. But, as they stood before the assembly of masters, a sudden flash of movement betrayed the tranquility of the scene. One of the elderly masters, his eyes glinting with a fierce inner light, launched a surprise attack on Mu Chen.

The young warrior, caught off guard, stumbled backward under the master's relentless assault. His body battered and bruised, Mu Chen struggled to rise, his determination burning brighter with each passing moment. Summoning the power of the Divine Artifact, he channeled its energy into a mighty counterattack.

The elderly master, his expression unreadable, absorbed the blow, only to reveal a hint of a smile as Mu Chen stood victorious. The truth dawned on the young warrior – the attack had been a test, designed to push him to his limits and unlock the secrets of his potential.

As the elderly master nodded in approval, Mu Chen felt an extraordinary surge of energy course through his veins. His cultivation level soared, his strength and agility increasing exponentially. The master's eyes sparkled with satisfaction as he posed the question, "Why have you come to the Lavi Green?"

Mu Chen and Aria exchanged a resolute glance before responding in unison, "We seek the Divine Gem, for it holds the key to saving the human clan from the demon's wrath." The elderly master's expression turned solemn, his voice laced with a hint of regret. "Alas, the Divine Gem has been stolen by the sea monster. If you wish to claim it, you must brave the dangers of the ocean and retrieve it from the monster's lair."As the elderly master's words hung in the air, Mu Chen and Aria exchanged a resolute glance. Without hesitation, they accepted the challenge, their determination to retrieve the Divine Gem burning brighter than ever. The masters of the Lavi Green nodded in approval, their faces etched with a mixture of concern and admiration.

With a deep breath, Mu Chen and Aria set off towards the ocean, the vast expanse of turquoise waters stretching out before them like an endless canvas. As they ventured deeper into the sea, the air grew thick with an eerie, unnatural silence. Suddenly, the waters erupted into chaos as a legion of sea monsters emerged from the depths, their twisted forms writhing like living nightmares.

The battle that ensued was nothing short of apocalyptic. Mu Chen and Aria fought valiantly, their movements a blur of steel and magic. However, despite their bravery, the sheer number of monsters began to take its toll. Aria stumbled, her body battered by the relentless onslaught, and in a heart-stopping moment, she fell to the ground, struck by the monster's cross sword slash. Her eyes fluttered closed, her body limp and still.

Mu Chen's world narrowed to a single, burning focus. Aria's fall ignited a firestorm of rage within him, and as he gazed upon her motionless form, a huge yellow light burst forth from his body. The energy enveloped him, imbuing him with an extraordinary strength that defied comprehension.

Transfigured by his fury, Mu Chen unleashed a maelstrom of destruction upon the sea monsters. His blows shook the ocean's foundations, sending creatures flying like rag dolls. The Divine Artifact, attuned to Mu Chen's rage, pulsed with an intense, golden light, as if feeding off his emotions.

Just as the last of the monsters fell, the King of the Sea Monsters emerged from the depths, its colossal form undulating with malevolent power. The beast hurled its full fury upon Mu Chen, unleashing a torrent of attacks that would have shattered any ordinary warrior.

Mu Chen, however, stood firm, the Divine Artifact's power coursing through his veins like liquid fire. With a battle cry that shook the heavens, he raised the artifact, and a blinding flash of light illuminated the darkening ocean. The explosion that followed sent shockwaves rippling through the water, obliterating the King of the Sea Monsters and shattering the surrounding sea floor.

As the chaos subsided, Mu Chen stood victorious, the Divine Gem glowing brightly in his hand. Aria, stirring from her unconsciousness, gazed up at Mu Chen with a mixture of awe and gratitude. Together, they made their way back to the Lavite Green, the gem's power pulsating like a beacon, illuminating the path ahead.
