Reborn Black Fox: Show Your Sword to Xiaoli at the Beginning!

[Anti-Japanese War Spy + No System + Cool Writing + Hot Blood + Major Classic Battles] When he woke up, military doctor Fang Tianyi traveled through time and became the male protagonist of the same name in "Black Fox". The time was September 19, 1931, the day after the September 18th national disaster! Facing Dai Li's solicitation, the reckless and passionate young man in the original work? No! In this life, I, Fang Tianyi, am the king of special warfare from the 21st century! In your childhood, were you still fighting with bayonets and engaging in primitive infiltration? It's so funny, I'm going to give you a dimensionality reduction strike package of "information warfare" + "decapitation operation"! Holding the script in hand, I have an insight into the future. The traitors and lackeys have nowhere to hide, and the Japanese military deployment is as transparent as before me! "Black Fox? No, from today on, we are ghosts!" Devil's week training, tactical sign language, alternate coverage... When the special warfare concept that was ahead of its time appeared in the 1930s, the entire military system was overturned! Dai Li was shocked: "How can this be an agent? This is clearly the whip of God!" Assassinate Doihara? That's just an appetizer! See how our Tianyi team builds the most powerful special forces team on the planet and turns the "Black Fox" into the Sword of Damocles hanging over the heads of all invaders! In this life, those who offend China will be punished no matter how far away they are! [It is slightly different from the original plot, so please do not read if you are concerned.
