Shadows of Espionage: Stalking Through the Dark Abyss

I transmigrated to Republican-era China and became a rookie in the Military Statistics Bureau. But nobody knows I'm a modern cryptography expert and an experienced criminal investigator. A Japanese spy's “perfect bombing”? I spot the flaw in three seconds. The Special Higher Police's “unbreakable cipher”? I can tell at a glance it's a Caesar shift. Deputy Station Chief Wu Qiming is corrupt and secretly working with the enemy? I set a trap with false intelligence and let him walk right into it. But Station Chief Chen says, “He's one of Boss Dai's men. Leave him be for now.” Leave him be? Who's going to answer for my brother's life? If the rules can't protect good people, I'll make my own. By day, I'm the youngest operations team leader in the Military Statistics Bureau, ruthless and decisive. By night, I'm the Red agent “Shenyuan,” weaving an invisible intelligence network behind enemy lines. Sato Kenichi, Yamamoto Yuji, the 76th Division's devil... You want to catch me? Come on. I'll teach you a lesson called “dimensional superiority.”
