Iron Bone Cast Edge

In the late autumn of 1937, artillery fire in Rugao, Jiangsu Province tore apart the tranquility of "Chen Ji Blacksmith Shop". Blacksmith apprentice Chen Tieshan witnessed his father sacrifice himself under the Japanese bombings to protect the steel. The family motto on the wall that "iron materials must be strong and people's hearts must be upright" was punctured by a bayonet. With the unique skill of tempering forged iron and the fury of revenge, this silent young man grasped the hammer tightly and stepped into the torrent of blood and fire. Without extraordinary powers, he relied on the precision of a blacksmith to repair jammed rifles, used quenched iron wire to make lock-picking tools to raid grain depots at night, and forged scrap steel into deadly landmines; without a natural talent, he learned from the "sparrow tactics" of guerrilla warfare, built anti-artillery fortifications with the rigor of an ironworker, and relied on his keen insight into metal to decipher Japanese intelligence signals. The artillery cover of the veteran machine gunners, the field treatment of the female medical staff, the tracking and exploration of the young scouts, and the material support of the gentry and country sages, the figures of the "Five Heroes" shuttled behind enemy lines in East China. From disrupting Japanese transportation lines to cooperating with friendly forces to defend Changsha, from deciphering Wang's puppet translator's conspiracy to confronting special forces commander Ichiro Miyamoto, Chen Tieshan used a hammer to forge sharp blades and defended his country with iron bones. When the trumpet of victory in the Anti-Japanese War sounded, the former blacksmith apprentices have become "iron masters" in the people's mouth. He did not miss military medals, but returned to the rebuilt blacksmith shop to forge the enemy-killing bayonets into plowshares for cultivation - this time, what he wanted to forge was not a sharp edge, but a foundation for peace. The iron fire is rekindled and the original intention remains unchanged. This is a passionate legend of a blacksmith who spent his life practicing "iron bones to forge the edge and protect China".
