Meng Fanchen traveled to the Magic City during the Anti-Japanese War. Fortunately, he had a special ability. He could accurately calculate the relevant values of anything he observed, such as the height of the wall, the length of the shoe print, the speed of the opponent's sword swing during the fight, the location and angle of the impact, etc. Not only that, he also had a photographic memory and the ability to observe things in detail. He could judge a person's general identity, what he had done recently, etc. From his clothing, traces on his body and living habits.
The only person with this ability must be an agent. The moment he arrived in Magic City, he started his anti-Japanese espionage journey, traveling across Magic Capital, base areas, counties and other places...
Really bad,,,,
