Thunderbolt Fantasy Sword Seekers 3

Shāng Bù Huàn is searching for the body of Lóu Zhèn Jiè, who fell into a ravine while holding the Seven Sacrilegious Dead sword. This sword is too dangerous to be left in the wilderness, but despite the efforts of Shāng and his three companions, the sword and the body remain unaccounted for. Advancing into the depths of the gorge, they soon discover a strange place...

Lóu Zhèn Jiè, having survived his battle with Bù Huàn, wanders within the Void Junction and is separated from the Seven Blasphemous Deaths when he touched a Scrying Mirror. He is then teleported to a world occupied by Guǐ Duó Tiān Gōng, a wizard from Xī Yōu. Upon learning the circumstances of Zhèn Jiè's arrival, the wizard proposes building a prosthetic arm for Zhèn Jiè in exchange of helping him re-open the portal back to Zhèn Jiè's point of origin.

Guǐ Duó Tiān Gōng succeeds in building a machine that would take him and Lóu Zhèn Jiè back to the Void Junction. But after ridiculing Zhèn Jiè's obsession with the Seven Blasphemous Deaths, Zhèn Jiè attacks the wizard and destroys the machine before entering the portal himself. Cháo Fēng reveals she has sent countless soldiers to their deaths finding Làng Wū Yáo.

Suspecting Bù Huàn has reclaimed the Seven Blasphemous Deaths, Zhèn Jiè uses a Scrying Mirror to take himself to Míng Huáng's lair, leading into a 3-way battle between Bù Huàn, Zhèn Jiè, and Jūn Pò. The intensity of the battle causes everyone to split up - Bù Huàn lures Zhèn Jiè away from Wū Yáo, who rests in a cave to recover his wounds; Xuě Yā (using his alias Guǐ Niǎo) joins with Jūn Pò to plot against Bù Huàn; Juǎn Cán Yún and Líng Yá make their way to the Odd Shack to seek help from Tiān Gōng Guǐ Jiàng, the creator of the Sorcerous Sword Index.

án Yún returns to Wū Yáo with the medicine from Guǐ Jiàng. Bù Huàn also returns after Zhèn Jiè loses his pursuit of him. After Wū Yáo recovers and learns of what happened, he berates Bù Huàn for not going to the Odd Shack himself to see Tiān Mìng.

In a flashback, Bù Huàn, Wū Yáo, and Tiān Mìng battle against Huò Shì Míng Huáng. The trio are forced to flee as Míng Huáng is too powerful and permanently blinds Tiān Mìng. In the present, Bù Huàn explains that he left Xī Yōu because he would not further risk the lives of his comrades for the safety of the Sorcerous Sword Index, and until the Index is safely secured, he could not visit Tiān Mìng. Bù Huàn's party then wait for the Scrying Mirror to take them back to the Void Junction and resume their search for the Seven Blasphemous Deaths.

Xuě Yā overhears Xíng Hài's plan to use the Void Junction to travel back in time to restore Zhào Jūn Lín's demonic form and informs Bù Huàn, whose party just arrived into the Void Juncton. Seeing no surprise reaction, Xuě Yā deduces Bù Huàn has used the Scrying Mirror to travel through time before. Wū Yáo rebukes Bù Huàn for not sharing this knowledge and use it to go back to the past and save Tiān Mìng. Xuě Yā uses a Scrying Mirror to forcibly teleport Bù Huàn and Wū Yáo away just as Yì Piāomiǎo arrives, while Cán Yún goes into hiding. Xuě Yā convinces Piāomiǎo that his conversation with Bù Huàn is part of a deceitful plot against him.

Lóu Zhèn Jiè and Wā̀n Jūn Pò arrive at the Void Junction and, upon seeing Lǐn Xuě Yā, Zhèn Jiè attacks him. Jūn Pò intervenes explaining that Xuě Yā is on their side. Azibělpher agrees to aid the sisters and begins the process of powering the Void Junction for time travel. Xíng Hài reports of Zhèn Jiè's arrival to Zhào Jūn Lín. The latter warns that Zhèn Jiè is dangerous and must be dealt with caution, and is angered when Xíng Hài assumes that her sister's weakened state was due to her using almost all of her magic to save Zhèn Jiè from death.

Jūn Pò informs Piāomiǎo of Huò Shì Míng Huáng's plan and laments his helplessness. Piāomiǎo tests Jūn Pò's loyalty by suggesting he ignore his master's orders to which Jūn Pò refuses.

Bù Huàn finds himself 200 years in the past during the War of the Fading Dusk and meets Bái Lián. Bái Lián explains he is from a different realm and was transported to this current location through unknown means. Seeing his swords have somehow gained magical powers, he gave the weapons to the humans to fight the demons, and eventually started forging more. Sensing Bù Huàn is from the future, he wonders if he is here to inform him on the fate of the weapons. Upon seeing the Sorcerous Sword Index, he realizes the destruction they have caused, and offers to take the scroll from him. Bù Huàn turns him down, relieved the source of the weapons isn't a divine being, and is happy to continue protecting the swords.

Xuě Yā kills Cán Yún using the Seven Blasphemous Deaths while Xíng Hài subdues Bù Huàn. Piāomiǎo snatches up the Index and bargains with Xíng Hài for Bù Huàn's survival in exchange for some of the swords. The two are unable to come to an agreement and Piāomiǎo hands Jūn Pò the Index while he contacts his master. He unsuccessfully attempts to usurp Jūn Pò, and Huò Shì Míng Huáng orders him to watch the general in case he does plan a betrayal.

Jūn Pò informs both soldiers of Xī Yōu and the Order of the Divine Swarm of the truth surrounding the Void Junction, as well as him being a double-agent, and intends to stop Zhào Jūn Lín. Despite the animosity from both sides, the soldiers choose to join Jūn Pò in destroying all the Scrying Mirrors. Jūn Pò sets Xuě Yā free but keeps Bù Huàn imprisoned due to his loyalty to Míng Huáng, and that he intends to fight Zhào Jūn Lín alone using the Sorcerous Sword Index. Jūn Pò then tells Bù Huàn that should the latter free himself somehow, they would have one final battle for possession of the Index.

Dān Fěi, Wū Yáo, and Cán Yún assist Jūn Pò's troops to drive off the invading demons, while Jūn Pò himself battles against Zhào Jūn Lín. He pulls several swords from the Sorcerous Sword Index, but are ineffective against Zhào Jūn Lín due to his association with the dark arts. Jūn Pò ultimately settles on a flaming sword that burns away at his body. Xíng Hài interrogates Bù Huàn until Xuě Yā arrives carrying still intact Scrying Mirrors, which he offers in exchange for Bù Huàn's release.
