On the third floor of the underground medical city, young doctor Lu Xun'an had just finished a thirty-six-hour shift. The surgical gown was stuck to his back, and the smell of disinfectant soaked into the seams of his bones. He pushed open the door to the lounge, and the old sensor light flashed twice before turning on. The communicator suddenly vibrated, and an emergency consultation notification popped up: A patient with severe pneumonia in the isolation ward of District 17 had a sharp deterioration in vital signs. Lu Xun'an took a sip of cool coffee, grabbed his coat and walked out. At the end of the corridor, the cleaner Old Chen was hunched over and mopping the floor. He raised his head and smiled at him with a missing front tooth: Doctor Lu, are you rushing to work again? Lu Xun'an nodded and kept walking. He didn't notice that a line of small words scrolled across the wall display behind him: The resource recovery sequence is being updated. When I arrived at the ward, the monitor was emitting a piercing alarm. The patient was a thin, disfigured middle-aged man with black mud embedded in his fingernails. He looked like he had just been lifted up from the lower mining area.
