I Transmigrated a Thousand Years and Became a Sword Immortal

In the Great Yin Dynasty, immortals and mortals coexist, and the Starfall Calamity returns once every three hundred years. Xie Guhan is reborn as the legitimate daughter of the Left Chancellor, though she is in truth a sword immortal reborn across a thousand lifetimes. She awakens the Myriad Worlds sign-in System. Watching the world with a cool gaze, she earns divine swords, divine armor, and formation diagrams through sign-ins, rising step by step. Crown Prince Pei Wujin is consumed by obsession and seeks to sacrifice the Eight Wilds in blood to force a resonance between their primordial spirits. Xiao Jingheng, the Prince of Zhenbei, has a murderous glint in his eyes, yet guards her with tenderness alone. She breaks through the deadlock with her sword, uncovers the truth behind the seal of Heaven and Earth, and joins hands with Xiao Jingheng to defy fate and change their fortunes, confront the Starfall Calamity, and reshape the order between immortals and mortals.
