This is an era in which the martial path has perished and the immortal path remains unknown. The Xiantian Realm is already the pinnacle of human achievement, the road to ascension has been severed, and the world's spiritual energy has changed. A sense of hopelessness pervades the world, as if every path forward has been cut off.
Twenty years ago, Jun Mowen, a prodigy of the Qingyun Sect, suffered a cultivation deviation during a battle at the peak of his power and "murdered" the person he loved. His reputation ruined, he vanished without a trace.
Twenty years later, a traveling physician known as the Wanderer of Wangchuan arrives in Qingzhou City. His left hand trembles, yet his medical skills are unparalleled. His memories are shattered, and he often hums a mournful old tune that no one recognizes.
Jiang Buwu, the leader of the martial world, hides an inescapable loneliness beneath his fairness and integrity. A broken jade pendant always hangs at his waist. When he meets the physician in Qingzhou City, a storm rises in his heart.
Su Jianxue, master of the Listening Rain Pavilion, built an intelligence empire to uncover the truth behind her sister's brutal death. When she comes to Qingzhou herself and hears, in a ruined temple on a rainy night, the tune that only her sister used to hum, the blade of her vengeance begins to tremble.
When the identities of healer and sinner, leader and brother, avenger and watcher intertwine in one person; when the Demon Lord's seal begins to weaken and ancient secrets come to light; when a truth delayed by twenty years begins to tear away every disguise...
They must face more than one another's blades. They must also confront the cruelest question of this era: when every road ahead has been cut off, should they cling to a decaying order or carve out a bloody new path? When a mistake cannot be undone, should they cling to punishment or find the courage to forgive?
A vast epic begins here.
Crossing tribulations, crossing tribulations: what are we truly crossing? The tribulations of the self, or those of this vast mortal world and its boundless, inscrutable Heavenly Dao?
