She is Sheng Xitang, the Sixth Princess of golden branches and jade leaves; he is Xiao Qingye, the Chief Eunuch who holds sway over the court and is known as the Nine-Thousand-Year-Old. By an imperial decree, she is forced into marriage with this incomplete man. What begins as a marriage of convenience gradually gives way to genuine affection amidst mutual testing—he slaughters her enemies, pacifies rebellious domains, and paves her royal road to emperorship, while she accompanies him out of humiliation. Finally standing side by side over the realm, they retire hand in hand to Jiangnan, fulfilling a long-overdue grand wedding.
