1. Core background
The modern city "Yunzhou City" appears to be an ordinary city with prosperous science and technology, but in fact it hides a group of "Xuanmai warriors" - a sudden drop in spiritual energy a hundred years ago caused a fault in the inheritance of ancient martial arts, and the warriors turned to underground development, forming a dual pattern of "bright side city + dark side martial arts world". Nowadays, the spiritual energy is slowly recovering, the sleeping mysterious veins are gradually awakening, the hidden martial arts forces are beginning to surface, and the lives of ordinary urbanites have been quietly changed.
2. Xuanmai System (Innovation Core)
The essence of Xuanmai: The spiritual energy channel hidden in the human body. After awakening, it can absorb the spiritual energy of heaven and earth and transform it into "Xuanqi". The quality of Xuanmai determines the speed and upper limit of cultivation. It is divided into nine levels, with the first level being the lowest and the ninth level being the highest.
Special mysterious veins: Regular mysterious veins have single attributes of metal, wood, water, fire, earth, wind, and thunder, while the male protagonist has the rare "chaos mysterious veins" (which have no attributes, are compatible with all mysterious veins, and can be integrated with attribute mysterious veins in the later stage), and the female protagonists each have unique variant mysterious veins (such as "mirror shadow mysterious veins", "withering mysterious veins", etc.).
Cultivation realm: Awakening realm → Condensing Qi realm → Transforming Gang realm → Tongxuan realm → Condensing spirit realm → Breaking the void realm (each realm is divided into early, middle, late and peak stages). The highest combat power in the current urban martial arts world is Tongxuan realm, and the Concentrating spirit realm only exists in legends.
