Earth experienced a cataclysmic event later known as the "Plasma Cataclysm."
High-energy plasma storms swept the globe, causing localized collapses of the laws of physics and creating a bizarre entanglement between electromagnetism, consciousness, and emotion. Human civilization was nearly wiped out within a few years, with over 90% of the population perishing, and existing nations, institutions, and technological systems completely collapsing.
Survivors discovered that: In extreme environments, emotions can be released as absorbable plasma energy—known as "Reiki."
Reiki is not naturally generated but originates from the emotional fluctuations of intelligent life.
Seven emotions correspond to seven types of Reiki:
• Joy
• Anger
• Sorrow
• Fear
• Love
• Hate
• Desire
Arranged from lowest to highest "concentration/usable intensity":
Joy → Love → Sorrow → Fear → Hate → Desire
In the post-cataclysmic world, cultivators rose to prominence, relying on absorbing the emotional Reiki of mortals for cultivation, and gradually forming a new ruling class.
Ordinary people are responsible for "living and having emotions," while cultivators are responsible for "managing, guiding, and reaping."
