Shen Changning, the most noble eldest princess (emperor concubine) of the Dasheng Dynasty, in order to consolidate the imperial power, tamed Xiao Jin, a lowly hostage sent by the enemy country, as an "obedient dog", and used her vicious methods to eradicate dissidents. She is aloof and gets everything she wants, but she doesn't know that this young man who seems silent and obedient, but is actually gloomy and sinister, has already been secretly grinding his teeth, sucking blood, and weaving a dragnet.
When Xiao Jin returned to the country, he mobilized millions of troops to attack the country, not for revenge, but to break the pride of Jinzhiyuye and imprison her in the deep palace.
Shen Changning was unwilling to be reduced to a plaything in the palm of his hand. In the gap between the harem and the former dynasty, with his extraordinary resourcefulness and skill, he fought back step by step from the imprisoned princess of the subjugated country, and launched an extreme struggle for power and conquest with Xiao Jin. In the end, the two saw each other's sincerity through misunderstanding and hatred, eradicated the hypocritical villain, and shared the country.
