Imperial Draco-Bull is a Draco-Bull that has the bloodline of a True Dragon flowing through its veins. This bull is already strong as a Godking and could have turned into a demon a long time ago. However, it wants to reach atavism and become either a True Dragon or a Divine Bull, so it chose not to gain intelligence using the dao.
Imperial Draco-Bull was Li Qiye's preferred mount to enter ominous grounds, like the 12 Forbidden Burial Grounds or Ancestral Earths. It was able to dispel poisons, detect dangers and evade them. At the same time, it could tread through any terrain.
