Reborn as a Young Marshal in a Time of War!

This book is based mainly on the Republican era and tells stories of resistance during the war! But what it actually depicts is an alternate world resembling that era, with absolutely no connection to our country's history. So please, do not associate this book with any historical events. Not at all! The book may reference some historical events, but it will use no real place names and mention no names of war heroes or warlords. In short, this is a story about resisting invasion in an alternate world after transmigrating there, and it has nothing to do with our country's history. Any resemblance is purely coincidental! Also, because of the System, some characters from TV dramas may appear, such as Li Yunlong and Zhao Gang from Drawing Sword, Xu Sanduo and Yuan Lang from Soldiers Sortie, and Leng Feng from Wolf Warrior. I hereby declare that I will absolutely not use any plots from these TV dramas or films. I am only borrowing the characters' names to flesh out the System! If any characters are later deemed off-limits, I will change their names!
