It is said that the Shangguan family and the Naijia family jointly created Dajiang. However, ten years ago, the Shangguan family was convicted of treason, leaving only an orphan girl imprisoned in Mao Mountain. Ten years later, Prince Naraku, who was determined to save the Shangguan family's orphan girl, went to the Shangguan family's hometown in southern Xinjiang to eliminate pirates. He unexpectedly encountered a pretty water bandit who kept saying that he would not marry him. The female water bandit called herself hope Taiping. She spent 50,000 sailors and went to the capital to apply for the prince. However, in the process of stalking Naraku, she showed her extraordinary intelligence. Only Li Ran, the Secretary of the Ministry of Justice, who secretly assisted hope Taiping, knew that she was Shangguan Banli, the orphan girl of the Shangguan family, and she came here to reverse the family case. Hope Taiping solved the imperial examination fraud cases, Jiangnan flood cases, etc., And also had a fierce fight with the princess An Ding at the edge of the town. Naraku also had a good impression of her because of the consistent stance of their families and countries. However, at this time, hope Taiping's substitute, the fake Shangguan Banli, also returned to the capital and was ordered to run for the crown princess. The palace, which was already full of conspiracies, fell into a greater whirlpool.
