Tianchu was supposed to be named Chu. A huge palace change caused the death of the emperor and empress, and the country fell into turmoil. Feng Ruge, the national teacher, took the initiative to take charge of the government. Over the past fifteen years, the growing prince has been determined to take back everything he has lost, but Tianchu is already ruled by the Feng Party...

The Nanjun country sent a princess, named as a marriage, but in fact it was to assassinate the prince and the national teacher, and subvert the Tianchu country...

What Jingshu didn't expect was that Lieying's only mission was to assassinate the prince, and Feng Ruge, who had always doted on her, actually had a blood feud with her...
