The protagonist is not a soldier or an agent, but a restorer of cultural relics across time and space. His golden finger is not a combat system, but a "comprehensive skill package for the 21st century": special criminal psychological profiling, top-level document anti-counterfeiting and identification, antiquities restoration, and modern medical common sense. He will use these skills to do more exciting work than a killer in Shanghai in 1937: forging a letter that can make the spy chiefs fight among themselves, repairing a broken painting that seems useless but actually hides a top-secret map, or using a few words of profile to make a well-trained killer collapse on the spot.
