This script was generated by AI. The Shen family's iron shop is declining day by day. After the father's death, making a living becomes difficult, and they are pressured by He Wantie of the Iron Guild to deliver thirty jin of wrought iron within a deadline, or else the family's heirloom anvil will be seized. Shen Qingya refuses to sell the anvil, and relying on his father's remaining notes, takes his younger brother Shen Xiaonian to the back mountain's abandoned mine to find a deep ore vein. He also visits his father's old friend, Uncle Tie, to learn the key secrets of smelting with Qinggang charcoal and quenching in well water. The two brothers overcome numerous difficulties, forging day and night, and forge the full amount of wrought iron on schedule to save the iron shop. Seeing the top-quality iron, He Wantie hands over a large order for farming tools.
