Whether it was called qi, lifeblood, or humors, the belief in such an essence  was common throughout the world, and still persists  in the stories of creatures who can somehow drain life from others, or some form of magical sources  that can replenish it.
Bilo da se zvalo qi, životna krv, ili humori, vjerovanje u takvu osnovu bilo je uobičajeno u svijetu, i još uvijek ustraje u pričama o bićima koja nekako mogu isisati život iz drugih, ili nekih magičnih izvora  koji ga mogu vratiti.
