Douluo: Infinite Soul Ring Stacking

Dragon Pillar Space: Contains three dragon pillars-the White Dragon Pillar on the left, the Gold Dragon Pillar in the center, and the Black Dragon Pillar on the right.

White Dragon Pillar: Strips all soul rings from the dead and stores them. Stored soul rings can be used to increase the age of your own soul rings. The maximum age attainable through stacking is determined by the age range corresponding to the color of the soul ring you have absorbed.

Black Dragon Pillar: Absorbs and stores soul bones that have not been fused. Stored soul bones can be used to increase the age of your own soul bones. The maximum age attainable through stacking is determined by the maximum age of the soul rings you have absorbed.

Gold Dragon Pillar: Strips martial soul essence from the dead. Stored martial soul essence can improve the quality of your own martial soul and allow you to briefly manifest it even when soul power cannot be used.
