Lin Fu, a graduate student in the Department of Modern History, accidentally traveled through the country and became Jia Heng, the concubine of Jia She in the Rongguo Mansion (there was no such person in the original work, a new character was added). This coincided with the time when Qin Keqing was staying in the boudoir and was about to be betrothed to Jia Rong. Jia Heng, who was well aware of Qin Keqing's tragic fate and the downfall of the Jia family, relied on his foresight to overcome all the objections before the clan marriage proposal, and married Qin Keqing with the bold statement that "the concubine is willing to be hired with military merit".
After marriage, he refused to indulge in the extravagance and glitz of the Jia family, and took advantage of the frequent wars in the northwest during the later years of Kangxi's life to resolutely join the army. Starting as a soldier at the border, he relied on modern military knowledge and accurate predictions of historical trends to repeatedly defeat powerful enemies on the battlefield: the remnants of Pingaldan, the invasion of Tsarist Russia, the suppression of the Tibetan rebellion, and the fight against the chieftains in the southwest. After hundreds of battles, he fought his way to the title of marquis in the light of swords and shadows.
He not only respected the original plot line, witnessed Bao Daichai's love-hate entanglement, and the ups and downs of Jia's family, but also relied on his military exploits to secretly plan to protect his wife and children, support the loyal, and attack traitors. He gradually broke away from the shackles of Jia's family and became a military force that cannot be ignored in the court. Qin Keqing also lost his original resentment and cowardice and became a solid support for his army's logistics. The couple played the piano and played the harp in harmony, and raised three sons and two daughters. The children all inherited their father's ambition, either on the battlefield or in charge of domestic affairs.
In the end, Jia Heng counterattacked from a concubine to become a powerful general who controlled the country, and was awarded the title of "Loyal and Brave King". Not only did he change the fate of himself and Qin Keqing, but he also guarded the peace of his family and country with his iron-blooded wrists at the cusp of the dynasty change, and wrote a military legend that traveled through the Red Mansions.
