The novels of the Three Kingdoms usually involved many fantasy elements such as summoning fierce generals. In Romance of the Three Kingdoms, there were many descriptions of the magical creatures summoned by generals, such as Lu Bu's Red Rabbit Horse, Zhang Fei's Leopard Head, Guan Yu's Green Dragon Crescent Blade, and so on. These summoned creatures usually had a certain level of strength and could give the general a certain advantage. However, these summoned creatures were not real. They were just fictional elements in novels and should not be regarded as existences in the real world.
