After traveling through time and becoming a cook of an independent regiment, Qin Muye just wanted to win the war of resistance. It just happened to have a deduction system attached to it - I would get a headache every time I used it, I would fall into coma if I used it too much, and I might become a vegetative state if I used it again. But Li Yunlong won't do it! "Xiao Qin, tell me a fortune teller. Where is the headquarters of that idiot Sakata?" "... Old Li, I am not a fortune teller." "Stop talking nonsense, you will faint after the calculation!" So the independent regiment has a geeky staff officer who "will faint before the war, and cheat when he wakes up." And - the stingy butler who "must count bullets after the war".
