Shen Yan, a boy of mixed blood from the Mystic Fire Tribe and the Icefeather Clan, has borne the secrets of both peoples and the mystery of his parents' disappearance since childhood. The Fengyan Sword in his palm holds the blazing heat of the phoenix bloodline, while the ice-silkworm feather in his pouch holds the chill of ice-spirit magic. The opposing powers of ice and fire tear at him from within, yet during one spell gone out of control, they unexpectedly awaken the sleeping parasol tree in the Bai family pharmacy. In its shadow, a vision appears: his parents fighting a bloody battle against the Corpse Gu King.
To uncover the truth, he sets out with his close friends Lu Yan and Su Wan. The supernatural exchange in Luoyang hides deadly schemes; the broken stele at Duanlong Cliff bears an unfinished final message; and the icy spring in Kunlun's Ice Palace reflects the protective spell his parents left behind. When the Corpse Gu King controlled by the Imperial Preceptor sweeps across the land, and the beast tribes unleash a devastating tide over an old grudge, Shen Yan finally understands the meaning of the Taiji spirit pearl in his palm. Fire must bring warmth, enough to warm scorched earth; ice must be gentle, soft enough to mend the cracks.
From the cooking smoke rising above the pharmacy in Xiangyang to the cold moon over the Ice Palace in the Kunlun Mountains, he uses a phoenix feather as his guide and makes a pact with the dual powers of ice and fire, forging the gentlest protection amid blood and flame. The souls of the departed become light in the earth's veins; the figures standing shoulder to shoulder become an unbreakable wall. And at last, he will understand: inheritance is never a shackle that binds one to the past. It means carrying love and memory forward, letting every wisp of spiritual power become a spark that lights the way ahead.
This is a story about growing up: about choosing forgiveness amid hatred, holding fast to new life amid destruction, and finding one's own path amid the pull of two bloodlines.
