According to the dark god Knull, the Sword of Fu Xi was a divine star-forged weapon with the potential to destroy worlds, though its true power could not be comprehended or unlocked by a mortal wielder.
The Sword of Fu Xi was found in the Qianfengou, the Valley of a Thousand Tombs by an professor and archaeologist, floating into a serpent-shaped red fog that emerged from a chamber grave robbers (including Hou Lao Er) opened (despite the Professor's and his guide's attempts to stop them, on archaeological preservation motives).
The professor brought it to Lin Lie, just before he disappeared.
As he tried to figure out his father's disappearance, Lin was driving himself crazy, and had nightmares, where he wielded the sword facing while Chiyou, the God of War, five thousand years, as the god was tearing apart the legions of Emperor Huang in the field of Zhuolu, until he froze before the god, saved by the sacrifice of his father.
Lin slashed his shoulder on it while ducking an attack from a demon. Instants later, the sword started flying through the air, maiming the assailant, but also preventing Lin from fleeing the place, until the arrival of Ji Shuangshuang.
After the War of the Realms, Lin Lie found himself in New York City, still on the trail of his father, using the sword to threaten his contacts, until Shang-Chi stopped him, who intended to help him, by first by training Lin to swordsmanship, and bringing him to live at his place.
At his turn, Shang-Chi had a nightmare where he warned Lin Lie of demons wishing to take the sword, but Lin Lie held it confidently and stabbed him. Awakening, Chang-Chi intended to get rid of the sword, considering it was too dangerous and could fell into the wrong person's hands, but Lin aggressively protested, the sword being the only link to his missing father. The two soon fled the flat, but were surrounded by undead giant warriors led by Ares, God of War, who managed to take the sword.
Upon learning that symbiote dragons were attacking Shanghai, Lin travelled there assuming they were minions of Chiyou. Upon learning from Aero that the symbiote dragons were servants of a different dark god, Knull, Lin was disappointed and stubbornly refused to assist in repelling the invasion, arguing that the Sword of Fu Xi had a proud will of its own and was meant to be wielded against Chiyou alone.
Angered by the boy's arrogance and hubris, the Sword of Fu Xi left him for Dane Whitman, the Black Knight, who had been stranded in Shanghai after a symbiote-dragon attacked him seeking to claim his Ebony Blade for Knull. Attacked by a symbiote dragon, the Black Knight lapsed into a berserk state - the Sword of Fu Xi belatedly realizing he wasn't a noble warrior and attempting to return to Lin. Lin and Dane's struggle over the blade was interrupted when the symbiote-dragon latched onto them with tendrils to mentally connect them to Knull; the Sword of Fu Xi setting Dane's hand ablaze with divine flames to force him to relinquish it before returning to Lin.
With Knull desiring to claim both the Ebony Blade and the Sword of Fu Xi for himself, Lin wielded the divine sword alongside Aero and the Black Knight in order to vanquish Knull's avatar.
