Chapter 558: Chapter 437: Dragon Bone Origin Qi! Ye Kong's Arrival_2

"Dragon Bone Energy!?"

Zhou Dao's eyes narrowed, finally understanding the purpose of the dragon bone.

The Primordial King Ceremony was held every thirty-three years, during which the power accumulated over the years was injected into the dragon bone by the twelve dragon veins.

Once the transformation was complete, all the Origin Qi would be absorbed and integrated into the body, merging into one and becoming Primordial King Qi.

At that time, those with Primordial King Qi would be real Primordial Kings.
