Qī Shā Tiān Líng

Qī Shā Tiān Líng (七殺天凌, Nanasatsu Tenryou, "Seven Blasphemous Deaths") is a major antagonist in Thunderbolt Fantasy. She is a sentient weapon that was sealed within the Sorcerous Sword Index by Shāng Bù Huàn. She has the ability to hypnotize those who look at her, and she and her wielder gain greater power the more blood she spills.

Personality
According to Xíng Hài, she is one of the Demon Realm's greatest sorcerers.

War of the Fading Dusk
The War of the Fading Dusk came to an end when the Demon Lord ordered a full retreat from the human realm. After passages to the demon realm were closed, the demon sorceress Zhào Jūn Lín remained trapped in the human world. There, she infiltrated the newly-established royal court of Xī Yōu and seduced the emperor.

The bloodshed and havoc she wrought from the shadows hangs over the Phoenix Light Palace as a modern day superstition that the royal bloodline is cursed by the same bloodlust as the demon sorceress.

Zhào Jūn Lín continued to torment humankind from this seat of power until her true nature was discovered. The Hù Yìn Shī attacked her; her body fell into the sea, but she transferred her soul into the Shén Huì Mó Xiè that killed her, becoming Qī Shā Tiān Líng. The sword was placed in a Hù Yìn Shī shrine, its guardians unaware of its true nature, for one hundred and fifty years until a descendent of the Hù Yìn Shī that killed Zhào Jūn Lín took up the sword. Enspelling him, she commanded him to kill his family. She passed from hand to hand in that manor, becoming an infamously dangerous weapon.

Sorcerous Sword Index
Sometime before Bewitching Melody of the West, Qī Shā Tiān Líng was captured by Shāng Bù Huàn and sealed within the Sorcerous Sword Index. She remains in the Index for several years leading up to Season 2 until she is unwittingly removed from it by Xiē Yīng Luò. Understanding how dangerous the sword is, Yīng Luò resists Qī Shā Tiān Líng on several occasions. However, when Xiào Kuáng Juàn turns on Yīng Luò after agreeing to work with her, Yīng Luò chooses to unsheathe the sword instead of allowing herself to die without accomplishing her mission. Yīng Luò wields Qī Shā Tiān Líng for a short time before shaking off her influence. Qī Shā Tiān Líng is then found by Lóu Zhèn Jiè who ardently takes up her campaign of bloodshed through Dong Li. Shāng Bù Huàn teams up with Lǐn Xuě Yā and Làng Wū Yáo to separate the two of them and seal Qī Shā Tiān Líng in the Sorcerous Sword Index, but Lóu Zhèn Jiè sacrifices his right arm to rescue her. The two plummet into a crevasse in the Demon Spine Mountains.
