Anti-War Check-In: My Reward Comes from the 22Nd Century

Time travel + Anti-Japanese War history + System check-in + Special operations + Group chat imagination. Start as a social animal and travel to 1937 with a blood-stained compass. You will become stronger by signing in on the battlefield, and you can even bring historical heroes into group chats! Form a god-level team and use future technology to reduce the dimensionality of the Japanese invaders. Every victory I have is continuing to write glory for China!
