In Harbin in 1938, the Kwantung Army Intelligence Department, the Special Higher Education Course, the Manchurian Railway Investigation Department, and the GPU Far East Intelligence Network were all entrenched here. The protagonist is ostensibly the owner of the "Time Gallery" on Central Street in Harbin. He specializes in restoring and producing various famous paintings. He behaves elegantly and slightly distantly, and is a well-liked gentleman in the social circle. But secretly he has a photographic memory, is proficient in seven languages and ten dialects, has ancestral traditional Chinese medicine + modern medical knowledge, and is also a master of psychology. Guess what he does!
