General He Lin, the protector of the country, returned to Beijing after ten years of war, only to find that his biological daughter He Jin had been replaced by Lulu, the nanny's daughter, and was also abused by her four adopted sons. He took revenge in anger, severely punished Lulu and his rebellious adopted son, and exposed the prince's conspiracy to frame the He family by replacing his daughter. After He Jinzhao recovered, he excelled in civil and military affairs and was awarded the title of General Protector of the Country. The father and daughter went on an expedition together to quell the war on the border, and eventually guarded the border side by side to protect the peace of the country.
