However, "high-interest loan" is a direct operation of the World's Laws, so it should be fine, right?
Thinking of this, Fang Ze couldn't help asking again, "By the way, mentor, you've prepared four metals. Does that mean we need to temper with each metal separately?"
Hearing Fang Ze's words, Qing Ya nodded.
She said, "Yes. The Bone Tempering stage is actually divided into four levels: Iron Bone, Bronze Bone, Silver Bone, and Gold Bone."
"Only after absorbing all these elements layer by layer into the body does the Bone Tempering stage reach Perfection."
"Only such a martial artist can have bones as strong as iron and gold, powerful penetrating power, and an even tougher body."
"Only then can they support the next stage: Organ Tempering studies."
After listening to Qing Ya's explanation, Fang Ze pondered and nodded, then asked again, "But... why use these four metals?"
"Wouldn't other metals work?"
