Haijin City, the most prosperous foreign concession in the Far East, is also the deadliest battleground in the espionage war.
Chu Wantang appears to be a Chinese literature lecturer at Haijin Girls' School and a celebrated Kunqu performer. In truth, she is the underground resistance group Spark Society's most elusive courier, code-named Lone Goose. She practices an unusual technique, the Heartlamp Art. It cultivates perception rather than combat, allowing her to detect lies and anticipate malice in the shadows. But her greatest weapon isn't her cultivation. It's her unshakable resolve: she never explains herself, and she never backs down.
When the traitor Shouzheng sells out the organization and their safe house is massacred overnight, Chu Wantang finds herself hunted from three sides. Her former fellow disciple, Li Hanjiang, vows to capture her with his own hands and prove that he made the right choice. The old monster Sato Qingyuan, a Core Formation cultivator, sees her as the most intriguing piece on his game board. Even her own organization begins to doubt her loyalty.
In a world where pistols are deadlier than flying swords and conspiracies sharper than cultivation, how can a female cultivator who cannot fight head-on wield her mind like a blade and survive in the heart of enemy territory?
When the truth comes to light, the traitor turns out to be the person she knows best. And when her final choice lies before her, escape or risk her life to send one last message, she says only this:
“The long night will end. The heavenly fire will burn forever.”
