After leaving the orientation, the sprouts began to register and fill out forms. Then they came to the square in line, watching rows of identical squads marching forward. They stepped briskly onto the square, running in formation. Their movements were neat and uniform, as they ran and sang: "Unity is strength! Unity is strength! This strength is iron! This strength is steel...",“This all organized by me” The sprouts couldn’t help but be amazed. The rookie guide didn't know when they had come behind them, smiling and saying: “Yes, isn't it unbelievable!”,“Rest assured! Those living near the people in danger have already been called to a meeting to discuss a rescue plan. Your biggest task right now is to integrate into our collective!”。
