The Sword Pavilion's Lowly Errand Boy

Chu Xiangnan lives with an old man in a remote village on Earth. When the old man dies, he leaves Chu only a broken sword furnace, an iron sword, and an old sword manual. Chu has barely finished burying him when a heavy rainstorm hits. While taking shelter on a winding mountainside, Chu slips and falls to his death, only to transmigrate into another world and take over the body of a lowly sword-forge errand boy who shares his name. How will he survive, and how will his sword shake the world?
