The Legend of the Hidden Sea was a historical drama, with Zheng Xiaolong as the executive director and Xiao Zhan, Zhang Jingyi, Zhou Qi, and Huang Jue as the leading actors. The plot described Zhinu, the son of Kuai Duo, the Imperial Astronomical Supervisor of Da Yong, who bore the grudge of the Blood Sea overnight. Ten years later, he returned to the capital under the alias of Cang Hai. With his construction skills and the art of conquering, he rose step by step in the imperial court. Finally, for the sake of the country's stability and the people's livelihood, he helped Da Yong eliminate the war. Xiao Zhan played Cang Hai in the play. His character was a contradictory and complicated combination. On the surface, he was calm, proficient in the art of crossing and scheming, but deep down, he did not give up the pursuit of justice and truth, nor did he erase his kind nature. Zhang Jingyi played the female lead in the drama. Her ancient costume was also praised, showing the agility and beauty of a young girl. As for Zhang Duo, according to the information provided, there was no relevant information about him, so he could not answer his role in the drama.
It depends on personal preference. If you like visual and audio entertainment, the anime might be better for you as it brings the story to life with animations and voice acting.
It depends. Sometimes the manga can expand on character development or introduce new plot elements not shown in the anime. But it's not always a straightforward comparison.
The Absolute Duo anime covers a significant portion of the light novel, but not all of it. Some key plot points and character developments are included, but there are still aspects from the original novel that haven't made it to the screen.
