Xuan Yuan Sword Luminary

Sisters Yin and Ning have been traveling the countryside together since since the evil Taibai Empire destroyed their town. Zhao, a friend from boyhood, was sold into slavery by the Taibai and now relies on his genius for invention and tinkering to survive as a subject of the Empire. One day, Yin unintentionally finds a legendary sword, giving her amazing fighting skills and enabling her to call forth Yun, a mechanical, mechanical fox spirit that swears to battle by her side. In the meantime, Zhao is swiftly becoming acquainted with a mystery young lady who might be incredibly powerful within the Taibai Empire. It will take all of the power and strength that the nascent resistance armies can gather to change the tide of war once and for all as Zhao and the Fu sisters find themselves becoming more and more entangled in the Empire's struggle for dominance over the nation.
