Walking with Red Sleeves and Sword

Once in a thousand years, I dreamed of entering the world of mortals, holding a sword with red sleeves and smiling at the spring breeze. A master of history traveled through time and became Su Jin, a disciple of a hidden sect. Thousands of years of memory gave her insight into opportunities, and the sword inherited for four hundred years gave her the foundation to establish herself. However, the memory fades due to the butterfly effect, and sword moves must be learned through hard work. Fighting for the right to inherit the throne, foreign troubles, and undercurrents in the world, she breaks through situations with literature and establishes herself with force. She will eventually answer the question: Why should she live a life that belongs to her in an era that does not belong to her?
