During the first year of practicing the "Geng Metal Immortal Sword Art," Su Yu smoothly completed the Foundation Establishment of the Immortal Body Taoist Foundation and entered the initial stages of the Geng Metal Immortal Sword Body. His bones underwent a transformation, and it seemed like his very essence underwent an extraordinary change.
In the third year of practicing the "Geng Metal Immortal Sword Body," Su Yu completed the transformation of the first Sword Bone, the first Earth Immortal Sword Bone transformed, condensing strands of terrifying Geng Metal sharpness.
Staring at the transformed Earth Immortal Sword Bone within his body, Su Yu's expression was solemn, and his heart was somewhat surprised and alarmed.
"This Sword Bone, how does it resemble the secret Dao Bone technique passed down by the Demi Immortal of Yan Palace so much!?" He compared the two, and they indeed bore great similarities.
