"Red Eyes and Cherry Blossoms" tells the story of Haoren, the abandoned prince of Yueben Empire, who suffers from rare red eyes and asthma, and lives in China under the pseudonym Xu Ren. His adoptive father died tragically, and the hatred between his family and the country was intertwined. He joined the underground party and took the code name "Son of the Devil" as a ghost agent to deal with the flames of war. His brother, Prince Huairen, was a military elite who invaded China based on his beliefs. The brothers took different paths on the battlefield. From the spies in Jinggang to the ice blood of North Korea, the red eyes reflect the shattered mountains and rivers, and finally burn away the dream of the military and the country with his life, leaving only his loyal soul to forever build a monument to peace.
