This is an experimental strategy RPG utilizing 3D environments with 2D character sprites set in an alternate continuity to the core Xuan-Yuan Sword games, but still contains a few elements related to Xuan-Yuan Sword 3. The protagonist Fu Zixun (輔子洵) is a young man who goes on a journey after of his clan's destruction and the Monster Fusion Vessel's theft caused by Jiutian (九天), the malevolent entity the protagonist's younger clan sister Zhu Yuanyuan (朱媛沅) accidentally unleashed. On his journey, he encounters allies including Ding Yun (丁芸), the kind and trusting daughter of a renowned doctor, Jiang Wushuang (江無雙), a bossy young girl who ran away from home and leads a group of bandits she defeated, Zuo Zhenhe (左震河), a respected and mighty guard leader for transporting goods, Qiu Qianli (裘千里), a skilled but kind-hearted thief, Leng Zhongqiu (冷仲秋), a stoic hero with a dark past, Qise (七色), a fox spirit with a feminine human form who is the elder sister to Jiutian, and Liang Cuo (梁錯), a slightly bumbling young man from a secretive family known for skills in engineering and the occult.

The group does not even know where their path will end, so can only forge their way ahead little by little, encountering monsters causing disturbances as well as evil government officials mistreating commoners. “Just what kind of world is this?” The group can only ponder in disapproval, yet they share a belief that drives them forward-a belief in a beautiful future. Even though monsters threaten the world and heroes rise in response, but the outcome is still unknown. They can only rely on their companies’ warmth to trudge through hardships together. All, with the appearance of the ancient weapon Xuan-Yuan Sword, shall eventually become clear.
