"I Practice Swordsmanship in the City" tells the story of Lin Fan, an ordinary social worker, who unexpectedly inherited the inheritance of the ancient swordsman and reforged the way of sword cultivation in the steel forest. He holds a rusty ancient sword, but the enemies he faces are the giants of capital, the torrent of data, and the ghosts of human hearts. When modern technology collides fiercely with the ancient sword, how will he use the sword in his hand to cut through the illusion and carve out a breathable gap for this numb era?
