Northern Border General Shen Hao risked his life to save the princess and intended to ask for her hand in marriage, but unexpectedly overheard her inner voice and discovered that she and the crown prince were conspiring to frame and harm him, prompting him to instantly ask for a death-exempt medallion instead. Using his mind-reading ability, he escaped poisoning, unraveled false accusations, and uncovered the conspiracy of the siblings poisoning the emperor and usurping the throne. Ultimately, Shen Hao toppled the crown prince and the princess, was bestowed the title of Prince Suppressing the North, let go of three years of misplaced devotion, and returned to the northern border.
