Devouring Heaven Demon Art

The Devouring Heaven Demon Art is a core cultivation technique developed by Empress Ruthless. It is designed to seize the fortune of heaven and earth, plundering the origin of all things to strengthen the practitioner 27 50.

• Matter Conversion: It can reduce matter back to its origin, converting it into pure cosmic energy to be absorbed by the practitioner 50.
• Physique Enhancement: A fully realized version of this technique can dissolve a mortal body and transform it into a special physique, effectively increasing one's gene multiplier 27.
• Continued Development: Hen Ren continues to refine the art alongside her studies of space-time laws and the Qi Kingdom Will Secret Art 117 285.

• Five Qi Towards Origin: A method that uses internal organs to sense and absorb cosmic energy, skipping the standard "five hearts" process to save time 3.

• Role as a Disciple: Xu Ai is a disciple of the Ruthless Councilor (Empress Ruthless), a connection that grants her significant status and influence 2 8 18.
