Soul Exchange: the Princess Goes to War for Me

In front of the Ningcheng formation at the border, Tuoba Yan, dressed in a female military uniform, looked at her face and said loudly: "Every inch of mountains and rivers, every inch of blood, anyone who dares to offend will perish his country! All officers and men, listen to my order, and Nanyi will not return it until it is broken!" Due to the soul exchange, Murphy traveled from the 23rd century to the body of the Daliang Prince Tuoba Yan, and went on an expedition on his behalf to regain the lost land and protect the country. Tuoba Yan held his beautiful face in his hands, with admiration in his eyes, and said with a smile: "Fei'er is so brave and fights for me personally. I can't repay you, but I can only pledge myself to you." Murphy: "As a man, you are not afraid of being laughed at if you do such an action." Tuoba Yan: "Don't be afraid, this face belongs to Fei'er, let alone what kind of face do you want to marry a wife?" … Let's see how Murphy, with his military medical system, can fight back the Southern Barbarians to their hometown, leaving the Northern Barbarians to capture them without help.
