Challenge: FIRST DIARY: "Red's Exposed Rook vs. Black's General – The Lesson of Heaven for the Victor" - Can you solve it?

This position is not a game, but a *test of survival* for a general. Red advances with an exposed rook on file 10, like a thrust through the iron wall of Black's defense. Their general and advisor stand atop the mountain, but all know: "*One wrong move will bring down the entire city*. Discover how Red *leaves no trace* in this battle—and why Black can only stand still as they are torn apart piece by piece."
