Background / History

Childhood and Naming

Gu Huaiwei was an orphan who survived by begging until he was seven or eight. An elderly beggar cared for him after his parents died, but the old man also died. Gu Wangchuan and the sword spirit of Sever the Heavenly River found him being beaten by youths trying to steal his last piece of flatbread 449 569.

The pair initially sought a mortal household to adopt him. Gu Huaiwei refused to remain with a family that had rejected him after learning his background, and begged to accompany the cultivators instead. The sword spirit persuaded Gu Wangchuan to test his Spirit Root and allow him to learn swordsmanship 570.

Before they parted, the sword spirit named him Gu Huaiwei. His surname acknowledged Gu Wangchuan’s role in giving him a new life; her accompanying advice was that he should remember his humble origins and use his strength to protect the weak. Gu Wangchuan supplied Spirit Stones and directions to an immortal sect, enabling him to enter the Flowing Light Sword Sect 449.

Search for the Sword Spirit

After becoming Sword Master, Gu Huaiwei sought Elder Buyun of the Heavenly Mystery Palace to locate the sword spirit’s human reincarnation. Buyun instructed him to visit Fantou Mountain ten years later, accept the first girl he encountered as his disciple, and never mistreat her. He also predicted that guiding her successfully could enable Gu Huaiwei to ascend 154.

Gu Huaiwei instead encountered Su Fuyun seven years after the prophecy and accepted her as his first disciple. Although her behavior increasingly differed from the sword spirit he remembered, he continued treating her as his benefactor’s reincarnation and the bearer of heaven’s mandate 154.

Sang Ying’s Neglect and Departure

Gu Huaiwei accepted Sang Ying reluctantly, out of regard for the sect master and elders. His favoritism extended beyond giving Su Fuyun resources: after she cried to him, he barred Sang Ying from visiting his residence 24.

He occasionally defended Sang Ying against outsiders and enforced Su Fuyun’s six-month confinement. Nevertheless, he asked Sang Ying to stop opposing her senior sister even while acknowledging that she had been wronged. Sang Ying refused compensation and obtained his permission to return to Settled Frost Peak after reaching Golden Core 23 24 26.

When Sang Ying later attacked Su Fuyun, Gu Huaiwei healed Su Fuyun and condemned Sang Ying. Sang Ying publicly severed their master-disciple relationship, accusing him of repeatedly sacrificing her interests for Su Fuyun 109 113.

Crippling, Fusheng, and Death

After the sect master ordered Sang Ying’s cultivation destroyed, Gu Huaiwei pursued her into the forbidden grounds and shattered her Golden Core. She stabbed his Dantian in return and escaped through a rift 114 116.

Gu Huaiwei subsequently accompanied Su Fuyun into the Devil Realm. After she disappeared, he was discarded in a black pool, where Demonic Qi repeatedly overwhelmed him. Reports reaching Sang Ying claimed that he had been killed 126 154 210 264.

He later appeared as Fusheng, without his former memories. Their return exposed his identity and renewed his fixation on Sang Ying, but she rejected his promises of protection and recognized Jiulian as her only master. Following his defeat, Gu Huaiwei was imprisoned in the Flowing Light Sword Sect’s water dungeon 440 442 443 446.

During Qi Yaoji’s attack on Sang Ying, he stepped in front of Sang Ying and received a weapon through his chest. Dying, he recounted his childhood and admitted that he had betrayed his benefactors’ hopes. Sang Ying and Jiang Zhuoxue later disposed of his remains, including burning his body to prevent its misuse 448 449 624.

Story Role / Major Arcs

The Other-world Gu Huaiwei

• Not a straightforward resurrection: The Gu Huaiwei who appears after the main-world cultivator’s death is a counterpart with memories of another world. Sang Ying learns this history through the Heart Devil Mirror 624 639 641.
• A failed attempt at protection: In his world, he raised another Sang Ying with extreme favoritism, taking opportunities from others while preventing her from traveling or sparring. His protection left her isolated despite her growing cultivation 639.
• Loss of his disciple: After that Sang Ying saved others, he failed to obtain the ten drops of heart’s blood needed to preserve her. Her remnant soul dissipated, and he killed the ten people who had refused to help 639 645.
• Interference in the main world: He arranged Su Fuyun’s involvement and sealed the main-world Gu Huaiwei’s memories. He claimed these interventions would prevent the same tragedy and force Sang Ying to develop resilience 636 641.
• A substitute for his lost disciple: Sang Ying rejects his claim to be her master, pointing out that he protects the Sang Ying of his memories but treats her suffering as a tool for fulfilling his own wishes 641.

Fusion of the Small Worlds

Gu Huaiwei persuaded Qi Yaoji that merging the five small worlds would give them a chance to ascend. Using an altar, rare treasures, and a tenth-grade Pill Furnace, he conducted a sacrificial sword dance that released gray Qi through the worlds’ barriers 629 630.

He then took control of the Devil Race, created armies without regard for casualties, and absorbed increasingly powerful devils. After consuming Princess Boruo’s heart, he fought Sang Ying and ultimately drew all the Lower Realm’s Demonic Qi into himself 633 634 635 637.

Heaven-mending Scheme and Defeat

Gu Huaiwei told Sang Ying that the Children of the Heavenly Dao were expendable Heaven-mending stones, created to repair a broken world. His plan was to leave only a small group alive—including her loved ones—then have her kill him and ascend. Sang Ying refused to let him determine her future 641 642.

She defeated him with the Dragon Abyss Sword and Divine Power, destroying his demonic form and rupturing his meridians. Although powerless and blind, he continued insisting that his actions had been justified. Qi Yaoji subsequently found him and tore out his heart 642 643 645.

Qi Yaoji’s Wedding and Final Sentence

• Qi Yaoji held Gu Huaiwei while preparing a wedding at the occupied Flowing Light Sword Sect. He refused the wedding robes, while she threatened to destroy everything Sang Ying treasured 665.
• Invitations named the supposedly dead Gu Huaiwei as the groom, prompting Ji Fucang and other cultivators to attend in hopes of reaching the sect’s captives 678.
• After their imprisonment, Sang Ying told him that his obsession had cost her other self the chance to live again. He finally recognized his responsibility for the suffering he had caused 685.
• The sect invited cultivators, mortals, and the Demon Race to witness his execution alongside Qi Yaoji 685.

What-if Timeline

• Sang Ying rejects Gu Huaiwei’s authority after awakening in a world where she is accused of injuring Su Fuyun. He expels her from his disciples, and she withdraws to Settled Frost Peak for a century 694.
• When Jiulian comes for her, Gu Huaiwei dismisses her departure as a tantrum. Her account of a dream involving a sword spirit unsettles him and makes him question whether Su Fuyun is truly the person he sought 702 703.
• Sang Ying separately exposes the other-world counterpart’s schemes. Ten Thousand Daos Born pursues him using a karmic thread and array-breaking disks, while he repeatedly releases Demonic Qi to obstruct capture 704 705.
• The local Gu Huaiwei eventually dies during his heart-devil tribulation without obtaining another meeting with Sang Ying 706.

Appearance

• Human appearance: Possesses a beautiful, delicate face and the lofty bearing associated with Immortal Venerable Yanchen. As a child, he was small, thin, and dressed in filthy, patched clothing 445 569 570.
• Fusheng disguise: Wears an iron mask, which Sang Ying splits apart to expose his identity 444.
• Other-world counterpart: Appears in a black hooded robe with a corpse-like pallor; later openly reveals his face 624 633.
• Monstrous form: Develops entirely black eyes, long horns, densely packed barbed black scales, and ten blade-tipped tentacles growing from his back 637.
• After defeat: Loses his horns, scales, and tentacles, but the damage to his eyes leaves him completely blind 643.

Personality

Gu Huaiwei’s early determination grew from poverty and a refusal to surrender his chance at cultivation. He trained diligently enough to become Sword Master, but eventually adopted the same distant superiority that had once made him vulnerable as a beggar. At his death, he recognized that he had forgotten the purpose behind his name 449.

His devotion is repeatedly expressed through favoritism and control. Believing Su Fuyun to be his benefactor’s reincarnation, he knowingly sacrifices Sang Ying’s interests for her. Even when his sympathy for Sang Ying briefly surfaces, he suppresses it upon thinking of Su Fuyun 24 96 154.

As Fusheng, his desire to reclaim Sang Ying remains possessive: he resents Jiulian’s position and becomes jealous of Jiang Zhuoxue’s closeness to her. His promises to become a better master do not acknowledge her right to reject him 442 443 444 445.

The other-world counterpart takes this tendency further. He wants Sang Ying strong enough to control her fate, but not free to defy his wishes. Even after engineering mass suffering, he insists that everything was done for her benefit 641 642 645.

Abilities & Skills

Swordsmanship and Ice Techniques
