Castle Sightseeing Notes

After finishing the morning's work, the doctor wanted to invite the operators who came for the afternoon shift to have lunch together, but the replacement operators had not yet arrived. When he was confused, he called the internal phone number, only to learn that the operator had disappeared mysteriously. An intelligence agent who often had contact with the doctor said that the operator appeared in front of an old castle not long ago. The doctor packed his bags, selected a few capable operators, and prepared to go to the old castle to find the missing operator. This novel and its characters are purely fictitious.
