Tempering with the Ice and Fire Dragon Kings' origin energy was the Pro Max version of tempering with the Icefire Immortal Herb. Every organ and every cell of Lin Feng's body, inside and out, was being scoured and cleansed by ice and fire energy.
The pain was so agonizing that he wished he were dead!
But in return, he could clearly feel his physical strength continuing to rise.
His body had already reached the utmost limit of humanity. To keep rising beyond that peak meant surpassing his limits...
Attaining godhood in the flesh!
Lin Feng had no idea how much time had passed. The torment had robbed him of all sense of time.
The Ice and Fire Dragon Kings' origin energy pouring into his body flowed through his head, torso, and both legs. Finding those places already occupied, it could only flow into his left and right arm bones.
Then it fused with his arm bones inch by inch. Nor did it stop there: a pair of dragon claws also fused with the bones of his palms.
Each of the Ice and Fire Dragon Kings had actually carried two Soul Bones: an arm Soul Bone and an external palm Soul Bone.
Lin Feng now possessed an unprecedented nine Soul Bones:
The Evil Eye Head Soul Bone, the Evil Eye External Soul Bone, the Deep Sea Demonic Whale King Torso Soul Bone, the Ice and Fire Dragon Kings' Left and Right Arm Bones, the Ice and Fire Dragon Kings' external palm Soul Bones, the Silver Moon Wolf Emperor Right Leg Bone, and the Blue Silver Emperor Left Leg Bone.
Nine whole Soul Bones!
"Roar!"
"Roar!"
Two deafening roars erupted from Lin Feng's body. They came from the remnant souls of the Ice and Fire Dragon Kings, hidden within their origin energy.
