Challenge: The Ultimate Checkmate: The Rook Takes the Palace When the Black General is Trapped - Can you solve it?

A simple chess position but filled with overwhelming lethal force. The Black General is trapped between two Elephants, the Guards are blocked from rescuing, and the Black Rook is as far away as a thousand miles. Meanwhile, the Red Rook is close to the palace, waiting for an opportunity to pierce through the General's defenses. This is not a battle of mighty warriors but a cold execution by precise and meticulous moves.
