Late at night, when everything was quiet, Fu Tao's mobile phone screen suddenly lit up, breaking the tranquility of the room. It was a housekeeping service call from an unfamiliar number. The voice was low and urgent, and the other party asked him to go to Dongjiao No. 8 Villa immediately for emergency cleaning work. Although it was late, Fu Tao took on this unusual task without thinking too much because of his sense of professional responsibility.
