Grandson of Elder Yun, also referred to as Jiang Xuirui. He is the new Marquis of Zhenbei of the Great Feng, known as the famed war god of the empire. He holds military power and enjoys the Emperor's trust. He watched the chess game through a half-open window and was deeply shocked that his grandfather admitted defeat to Song Nian Yun. He had grown up learning chess from his grandfather and possessed extremely sharp judgment. He compared Song Nian Yun to another brilliant woman of the same surname, Song Zhijin, who had been blinded by emotions and lost her life for someone unworthy.
