On the wedding night, the bride Yan Donghuang waited for her husband in the bridal chamber, but unexpectedly he brought back a pregnant woman, threatening to take her as an equal wife. As the War God Eldest Princess, Yan Donghuang felt extremely angry and questioned her husband on the spot, but didn't expect that behind all this was a conspiracy set up by the emperor and the empress dowager, attempting to seize the military power in her hands. Yan Donghuang was unwilling to be at the mercy of others, intending to settle accounts with corrupt officials and treacherous flatterers, and tear off the hypocritical mask of the royal family. In just seven days, she stirred up the political court, declared war on the ungrateful imperial power, and set off a huge change that shook the Dayong realm.
