Even though the pain made Lin Mu shiver, his will was unshakable.
The process of the gold being assimilated into his bones was a strange and painful sensation. At first it was simply like a heavy bag being tied to his bones that pulled it down. But then it felt like something was biting into his bones.
The biting sensation later turned into a drilling pain that was significantly worse than before. His hand and even the entire body trembled as the gold continued affecting him. Lin Mu's other hand was clenched tight, so much so that if he had not completed the first stage of the True Gold Body Forging Arts, his nails would have dug into his palm's flesh and drawn blood.
He bore through the pain and continued to cultivate using the mnemonic of the True Gold Body Forging Arts. Hours passed by as the pain slowly lessened. He didn't know if it was just him getting used to the pain, or if his body was actually adapting to it.
