Her name is Shen Yuzhi, the eldest princess who protects the country. She has a golden branch and beautiful leaves, but she married herself into a prince's mansion that is hidden and scheming.
Her name is Yan Beitang, the orphan of Dingbei Marquis. She was the queen of the general family, but she was trapped in the capital as a hostage for six years.
Seven years ago, outside Yanmen Pass, a cold arrow shot through the chest of Mr. Yan Laohou, nailing the fate of the two people together. In a pool of blood, Shen Yuzhi promised to "protect my Yan family", but after returning to Beijing, she was pushed into the Pei family by a fake memorial from the queen. Yan Beitang looked at the princess who had cut out arrowheads for wounded soldiers to put on her wedding dress, and sent only four words: Changle Weiyang.
Everyone thought they were broken.
Only Yan Beitang knew that Shen Yuzhi married into the Pei family to investigate old cases. Only Shen Yuzhi knew that Yan Beitang had never put down his sword in the six years since he was detained in Beijing. Two people are separated by an imperial city and a marriage contract.
