The Great Xia Empire has enjoyed three centuries of peace, but beneath the surface, dark currents surge.
Prince Wei, Xia Xiao, is a peak Martial Saint. Disinterested in power struggles, he retired to Feng City. When his son, Xia Feng, was born, purple auspicious clouds appeared in the east. The emperor personally bestowed a name and fief upon him, and everyone said the boy was destined for greatness.
But no one knew that Xia Feng died at fifteen.
He died in a carefully orchestrated "accident," his remains left in the wilderness. Then he came back to life: a soul from another world took over his corpse, bringing with it Tang poetry, Song lyrics, military strategy, Daoist classics, and the memories of an entire civilization.
He thought he had transmigrated into a martial arts world, until the sword intent that had lain dormant within him for a thousand years awakened.
Lingyun Sword Immortal, young master of the Lingyun Sword Pavilion in the Nine Heavens Realm, had his sword shattered and soul scattered when his junior betrayed him. A fragment of his remnant soul clung to a shard of his sword and fell into the mortal realm. He had waited a thousand years for this moment.
From then on, the martial world gained a freak.
Before a mighty army, he plays a song called "Xia," leaving enemy generals terrified to their core. In court, he recites a poem and leaves all the civil and military officials speechless. With The Art of War, he leads a hundred thousand troops around by the nose. At the brink of life and death, he draws his sword, and ten thousand swords answer his call.
Some call him an immortal banished from the heavens; others say he is a demon reborn. He only says, "I'm just an ordinary guy who can recite a few poems and perform a few sword moves."
From Feng City to the martial world, from the martial world to the court, from the mortal realm to the spirit realm. One sword, one jug of wine, one song.
Watch as the young Xia Feng shatters the void with a mortal body and shakes the Nine Heavens with his sword song.
Maple leaves fall beneath a frosty sky, and the sword song rings on.
