Start Practicing with Copper Skin and Iron Bones

The Dark Ages ended the ancient times, with distinctions between superiors and inferiors, and distinct classes. In a dark alley, a bookworm who likes ancient poetry is possessed by golden light. "The ancients first went through skin, meat, and bones to refine their bodies. There is an idiom for this, called copper skin and iron bones." Wen Sihu thought it made sense, swallowed a hundred kilograms of copper and stone, and began to refine the skin, bones, and flesh, to understand the Vajra Body; to refine the five internal organs, to understand the explosive fire; to refine the sinews, blood, and marrow, to understand the five qi toward the origin. "A strong man in ancient times left a poem: One body traveled three thousand miles, one sword once served as a million soldiers." Wen Sihu nodded, swallowed the ancient soldiers, condensed a flying sword in the golden light, and began to evolve: black iron sword, golden crystal sword, purple gold sword... ………… Boss: Why did you join the army? Smell like a tiger: As the ancients said, if the heavens move vigorously, the soldiers will strive for self-improvement. The boss is satisfied: This sentence is good, what else did the ancients say? Wen Sihu scratched his head: The friendship between soldiers and sons... Is as light as water? The boss's expression changed: "What you said, it's best not to mean what I thought."
