Spy War Codenamed a Piece of Ocean

[Parallel World + Spy War + Chinese Martial Arts + Microsystem] Jiang Zhengchang traveled through a parallel world and became an underground intelligence worker of our party. He inherited the family's "knife killing" skills. He worked hard to practice his knife skills and used Ocean coins as flying knives, thus getting the code name "A Piece of Ocean". He quietly sneaked into the Special High School to serve as a Japanese translator, collecting intelligence for the nation and performing assassination missions. He was able to kill with one hit every time he attacked, establishing his status and continuing to contribute to the victory of the Anti-Japanese War.
