The Nightblood Prince Summary: Full Story Deep Dive
Spoiler warning: The following section covers the plot from beginning to end, including the ending.
Part One: The Empress Promised by the Stars
As an infant, Fei is found bearing a phoenix-shaped birthmark. A stargazer named Yinxing declares that a fallen goddess with this mark will rule a united An’Lu.
Emperor Rong ties a red string of fate between the baby and his son Siwang. Fei is taken from her family and raised in the Yong’An palace as a child bride.
Siwang is gentle and devoted, but Fei feels caged. She suffers recurring visions of Yong’An burning and of mass slaughter.
At seventeen, during a winter pre-hunt gathering, Prince Lan Yexue claims the season’s first kill. The hostage prince from conquered Lan causes outrage at court.
Fei decides to hunt a legendary Beiying tiger at night. Tradition grants any wish from the Emperor to whoever kills one, and Fei wants her betrothal annulled.
In the icy woods, she finds Yexue wounded by a poisoned imperial arrow. She treats him with a rare antidote, then a tiger attacks.
Fei shoves Yexue clear, takes fatal claw wounds, and kills the beast with a dagger through its eye. As she dies, Yexue feeds her his glowing dark crimson blood.
The wound heals completely overnight. In a hidden cave, Yexue offers to help her escape to Lan, and she refuses.
Siwang and his soldiers find them. Yexue slaughters the soldiers at supernatural speed and gravely wounds Siwang.
To save Siwang, Fei stabs Yexue with his own blade and rides back to camp. Once Siwang recovers, she publicly refuses to marry him.
The Emperor raises a sword at her, and Siwang spends his own tiger-hunt wish to spare her life. Fei swears never to marry anyone else.
Enraged, the Emperor banishes Fei and her family to Su’He. Before she leaves, Siwang gives her face powder to hide her phoenix mark.

Part Two: Empires Rise, Empires Fall
Three weeks into exile, war breaks out. Yexue returns to Lan after his uncle’s death, seizes power as prince regent, and launches a campaign against Rong.
Fei leaves her family to find Yinxing, the stargazer behind her prophecy. Twelve months later she reaches Duhuan, a western border city.
There she finds Yinxing’s mother murdered, with “Heaven’s mandate cannot be defied” written in blood. Fei foresees a Lan attack and warns the villagers before returning home.
Lan’s army, supported by vampires Yexue created, pushes Rong’s forces steadily north. Molly X. Chang shows the war through peasant taxes, conscription, and burned cities.
A conscription scroll orders Fei’s frail father to enlist. On her nineteenth birthday she drugs her family with jujube seeds and steals the notice.
Disguised as a male soldier named “Li Fei,” she joins the Third Army under Commander Wu Caikun. Siwang arrives as commanding general and recognizes her during a public spar.
He admits Rong is losing to Yexue’s undead army. That night they share an intimate encounter in his tent, after which Fei foresees Siwang dying in battle.
Siwang leaves for the front at Changchun, leaving his stallion Beifeng and silver-tipped bow. Fei rides to the front to protect him.
She stabs a vampire with the silver tip, and it crumbles to ash, revealing silver as the creatures’ weakness. Fei is run through the chest, and Yexue again heals her with his blood.
He gives her seven days to leave the war. Rong begins forging silver weapons, but Yexue ambushes the camp and captures Fei.

Part Three: The Nightblood Prince
Yexue takes Fei to his own lands, including the prosperous cities of Longyan and Xiangxi. She meets Ping, the stargazer’s blind and mute disciple, whose eyes and tongue the Rong Emperor removed.
Ping writes that Fei’s fate will save or ruin the continent, depending on her true love. Fei also learns how Yexue turns dying soldiers into vampires with his blood.
She then foresees Siwang’s plan: burning Changchun with fire powder, sacrificing 20,000 trapped Rong civilians and soldiers to destroy the occupying Lan army.
Fei escapes to stop him but arrives as the city is consumed by flames. Horrified by what Siwang has become, she confronts him, and Caikun attacks her in grief.
Caikun eventually agrees to return with Fei to save Siwang from Yexue’s retaliation. On the battlefield, Yexue breaks Siwang’s sword hand and cripples him permanently.
Fei steps between them with a silver blade and challenges Yexue to an archery match to stop the massacre. Yexue wins but agrees to a peace treaty.
His condition is that Fei govern the borderlands with her own army, so she is never again a helpless pawn. Siwang signs the treaty and is appointed grand general.
Fei’s father is restored as court advisor. Fei bids farewell to her father and Siwang, then rides Beifeng to Changchun to command her own army alongside Yexue.
