In the third year of Jianzhao's reign, Xiao Xuechen, the treacherous prime minister who had returned from rebirth, grasped the blood-stained sapphire plan and met the abandoned prince Xie Linyuan who was collecting medicine in the ruins of the cold palace. He recognized these eyes - when his eyes were gouged out in his previous life, this man had the life-saving red crane crown hidden in his fingertips.
