Late at night in Yuncheng, a weak alarm sound came from an attic in an alley. Tang Nian, the quietest female student in the new school, was stuffing a pile of information into the middle of her cheongsam. The next day, she was blocked by Warlord He Cheng's motorcade on the street. The man rolled down the window and glanced at her: "Miss Tang, the stitching of your cheongsam is not right." Tang Nian smiled without changing his face: "He has a good eye, Warlord He." When she turned back, she found that the information in the cheongsam had been replaced by another one - it read: "Be safe. One of our own." She clutched the note with sweaty palms. The whole city was spreading rumors that the warlord He Cheng was ruthless and would rather kill the wrong ones than let them go. Only Tang Nian knew that every time she was in danger, there was always someone who would clear the way for her one step ahead. Until an ambush, she saw with her own eyes He Cheng blocked a shot for her, gritted his teeth and said in her ear: "Comrade Nightingale, I will cover you."
