Lin Xiaren was originally the son of the Minister of Hubu, a talented young man from Jiang'an City, and a talented man in both civil and military fields. Before his father was exiled, he pretended to be a fool to save his life. Three years later, Lin Xiaren recovered from his dementia. In order to clear his father's name, he resolutely embarked on the road of joining the army. But because of his lameness, he had to work as a pawn raising horses. However, with his keen judgment and excellent military talent, he dared to sneak attack the vanguard camp of the Beihan Army with only twenty horses and attack Gula City at night. He has repeatedly made military exploits, and used his body as bait for the rebel rebellion in Pingula City, and was in danger of death.
