On a rainy night in the south of the Yangtze River in the 15th year of the Republic of China, Su Qingyuan sent away the last coughing child, locked the door of the clinic and was about to return home, when suddenly there was the sound of heavy objects falling to the ground in the alleyway. She originally wanted to avoid the trouble, but the weak moan of "Save... Save me" touched the doctor's instinct. After turning back, she found a man covered in blood and shot in the waist and abdomen. His identity was exposed by the commander's badge on the collar of his military uniform. Su Qingyuan struggled between "causing trouble" and "saving lives and injuries", and finally decided to drag the man to the clinic for shelter from the rain.
