Zhao Qingyuan traveled through time and became a handyman in the border garrison who couldn't even eat enough. The good news: She has a great voice, a natural fairy voice that can soothe people's hearts. Bad news: The border war is tense, the enemy troops are pressing on the border, the morale of the entire army is low, and there are even deserters. General Shen Lie looked at the thin Zhao Qingyuan and frowned: "The military camp is not a place for entertainers. If you don't want to starve to death, go to the kitchen and light a fire." Zhao Qingyuan looked at the gray-eyed soldiers and thought that if the battle continued, the entire army would be annihilated, so she spoke. The song broke for a while and the sound shook the sky. The originally desperate soldiers seemed to have their souls injected into them. They clenched the rusty swords in their hands and forced the enemy back three miles. The whole army was shocked: "What kind of sorcery is this?!" Zhao Qingyuan wiped the sweat from his forehead and said weakly: "This is called psychological tactics, do you understand?" From then on, Zhao Qingyuan became the "group favorite" in the army. General Shen Lie went from being disgusted at the beginning to protecting his shortcomings: "Who dares to touch Qingyuan? Ask me about the sword in my hand first!" The enemy general was even more frightened after hearing this: "Don't attack that city, there is a singing monster in there. After listening to her singing, all the soldiers under my command want to go home and farm!" In fact, Zhao Qingyuan doesn't have any golden fingers. She just tries her best to turn every note into a protective force in the cruel battlefield day after day. This is not only a war about voices, but also a game about beliefs.
