According to the information Mr. Liang knew, the so-called "Red Rose" was an organization formed by a small group of early European mutants, known as "Blood-eating Creatures".
These blood-eating creatures, who had transformed from humans and declared themselves the "Blood Clan", satisfied their blood-drinking needs with human blood from the very beginning, and developed various characteristics for "hunting" and "influencing" ordinary humans through this mutation.
Although this type of "Blood Clan" was scarce, in the early days, they thrived among the European aristocracy, affecting many people through their traits and abilities, and even groomed a group of followers who touched the core of power in Europe.
However, in the early days, let alone banding together into an organization, they even viciously fought and wrestled each other, dragging ordinary people and various national forces under their control into their conflicts.
