This is a world where everyone has scales to fight. Scale holders are passed down from generation to generation, and the reverse scales enjoyed by a few people are famous for devouring the surrounding elements and releasing fear. The first people became emperors because of the reverse scales. However, some emperors were strong and weak, but were eventually overthrown by ordinary scale holders and became a common nation. A common nation is different from an empire. An empire is the strongest of one person. Although a common nation seems peaceful, it is also full of dangers. The male protagonist is an ordinary citizen of the Commonwealth who holds the reverse scale, while the female protagonist, as the sole heir to the emperor of the Tianwei Empire, is an ordinary scale holder.
The so-called scales are dragon horns. For humans, they are weapons with different characteristics that are combined with the body, or directly or indirectly linked to the body. They are composed of fish scale-like cards that can be controlled by the mind, fused into the body, and summoned the body's "scales".
Intention: Perseverance and self-improvement
