Luy_Nguyen_Van

In the late Trần Dynasty of Đại Việt (ancient Vietnam), the kingdom is in turmoil. The royal court is weakened, and threats from the Champa kingdom loom at the borders. The martial world is shaken by the legend of the Long Tàng Secret Manual, a martial arts scripture hidden beneath the waters of Lý Sơn Island. This manual not only contains supreme martial arts techniques but also a map of the nation’s dragon veins — knowledge that could either save the country or bring it to ruin if it falls into the wrong hands.

Phạm Quang Minh, a young disciple of the Thiên Vân Sword Sect, carries the sorrow of his exterminated clan and becomes the sole keeper of the secret manual. Wandering to the shores of Lý Sơn, he encounters Nguyễn Bích Thủy, known as the Bích Hải Dragon Maiden, the daughter of a former naval commander wrongfully executed for treason.

Initially enemies, Quang Minh and Bích Thủy gradually come to understand each other, realizing they are both children of men betrayed by the court. They join forces against the sinister Huyết Kiếm Sect, led by the formidable Lê Hồng Liêm, who seeks the manual to sell its secrets to Champa and dominate the martial world.

Their struggle entangles other factions:

Cửu Lạc Society, a neutral but cunning group.

Kim Xà Sect, spies serving Champa.

Hoàng Tùng Lâm, known as “The Lone Sword of Đại Lý,” a righteous warrior from the Tày ethnic group, harboring a vendetta against Huyết Kiếm Sect.

Through treacherous battles across beaches, mountains, and hidden caves, Quang Minh and Bích Thủy’s bond deepens, yet they remain torn between love and the debts of family and nation.

In a climactic battle atop Lý Sơn, Bích Thủy sacrifices herself to save Quang Minh. With her dying breath, she entrusts him with the Bích Hải jade pendant, the only proof of her father’s innocence.

Devastated by her death, Quang Minh destroys the Long Tàng Manual, refusing to let it fall into any faction’s hands. He then defeats the Huyết Kiếm Sect, but the kingdom remains unstable.

Choosing to leave the martial world behind, Quang Minh retreats to the Bạch Mã mountains, becoming a legend whispered among rivers and seas. It is said that on moonlit nights over the waters of Lý Sơn, one can still hear the mournful flute of the Bích Hải Dragon Maiden echoing across the waves.

The Chronicle of the Hidden Dragon in the Azure Sea

The wind howled across the ancient pine trees, sweeping snow into a dance of chaos. Atop the snow-covered summit of Snowy Peak, Quang Minh stood still as stone, his gaze locked onto the figure before him — Lãnh Phong. Once sworn brothers in arms, now bitter enemies.

"What are you doing here?" Quang Minh's voice cut through the cold like a blade.

Lãnh Phong offered a faint, mocking smile, his fingers brushing the hilt of his silver sword. "I came to reclaim what's mine... and to end this karmic bond."

Quang Minh let out a bitter laugh. "Yours? The trust of our master? Or the legacy of the Cửu Hà Sect you betrayed and trampled on?"

"Spare me your righteous speech!" Lãnh Phong's voice tightened. "If it weren't for your schemes, would Master have chosen you over me for the 'Nine Yang Ice Heart Manual'?"

Quang Minh said nothing. There are truths too old to prove, and wounds too deep to heal.

Behind them, soft footsteps brushed the snow. Thiên Nhi — the woman who once stirred the hearts of both men — emerged in a white fox-fur cloak. Her eyes shimmered with sorrow and complexity.

"Stop it… Both of you are wrong," she said gently, yet her words cut like frost.

Lãnh Phong turned to her, voice raspy. "I have no way back. Those who betray me shall not be spared."

Tears welled in Thiên Nhi's eyes. "Brother Phong, would you truly stain your hands with your brother's blood?"

Quang Minh stepped forward, calm as the falling snow. "No more words. One duel — let this be the end."

Lãnh Phong drew his sword. Snow scattered. Quang Minh summoned his inner force, his right hand glowing faint blue — the icy pressure of the ninth level of the Ice Heart Nine Yang surged.

The two shadows collided in a flash of light and frost. Sword energy tore through the wind. Frost fists shattered snow. A deafening roar cracked through the mountain as an avalanche thundered down the slope, shrouding the peak in a storm of white.

Long moments passed. From within the thinning veil of snow, a bloodied figure staggered to his feet — Quang Minh, his robes soaked in crimson, clutched a shattered blade.

"You… spared me?" came Lãnh Phong's broken whisper from the cliff's edge.

"It wasn't me who spared you. It was Thiên Nhi..." Quang Minh said, turning his back, leaving behind a trail of blood across the endless snow.
