THE DUAL CORE SYSTEM (二重核システム)
Exclusive to Ren Tenma
Achieved through the forbidden cultivation method "Tenshō no Sho" (Heavenly Ascension Scripture).
How It Works:
1. First Core (父核 - Father Core): Contains Hikari's Solar inheritance
2. Second Core (母核 - Mother Core): Contains Sayuri's Infinite inheritance
3. Cores orbit each other in perfect synchronization
4. Energy cycles between them, amplifying infinitely
5. Creates a perpetual motion system of power
Advantages:
• Infinite stamina (self-replenishing)
• Can use both inheritances at 100% simultaneously
• Power compounds exponentially, not additively
• Regenerates from conceptual erasure
• Exists in quantum superposition (simultaneously one thing and another)
Drawbacks:
• Constant pain (body rebuilding itself constantly)
• Risk of core collapse if synchronization breaks
• Shortened emotional range (sacrificed to achieve balance)
• Cannot be copied or taught
