Xuan Yuan Sword Luminary

Yin and Ning are sisters who have roamed the land since their village was destroyed by the cruel Taibai Empire. Their childhood friend Zhao, now enslaved by the Empire, survives by using his skill as an inventor to serve his captors. When Yin stumbles upon an ancient sword, she gains extraordinary combat abilities and the loyalty of Yun, a mystical mechanical fox spirit bound to her. At the same time, Zhao befriends a mysterious girl who might wield significant influence within the Empire. As the sisters and Zhao become entangled in the Taibai's struggle for dominance, the growing resistance must rally every ounce of magic and strength to challenge the Empire and end the war.
