Zhao Yufu traveled through time and became an orphan singing girl during the war. Good news: God has given her a wonderful voice. Bad news: In this world where life is so fragile, beauty and singing are life-threatening talismans. The local ruffians coveted her beauty, and the wealthy bullies wanted to imprison her. In order to survive, she sang the humblest song and showed the most flattering smile. Until one day, in order to rob her, they beat to death the only mother-in-law who had ever given her warmth. At that moment, the chord in Zhao Yufu's heart broke. From then on, she put away her smile, hid her singing voice, and picked up a rusty knife. Everyone thought that the weak and orphan girl who could sing was dead and died in a corner where no one cares. No one knows that she tempered her muscles and bones in the mud and sharpened her blade in the blood and fire. When she appeared again, a song of "Bro Zhen" resounded throughout the three armies, and the soldiers' blood boiled and their morale was as high as a rainbow; a song of "Guang Ling San" confuses the enemy troops, making them disorganized and defeated. The former bully became a prisoner, and he knelt in front of her and trembled: "You... Aren't you a singer?" Zhao Yufu wiped the blood on the blade and smiled, her voice was like pearls, but it was chilling to the bone: "Yes, I sing, and I also send bells."
