The Duke's Contracted Fiancée manga was from Japan. The name of this work came from a romantic story between a duke in Japanese history and his fiancée. This story was often adapted into comics, novels, and other forms of literature, and was loved by readers all over the world.
Maybe Duke is doing it to achieve a certain goal or to protect someone or something important. There could be multiple reasons behind his actions that are yet to be revealed in the manga.
" The Battle of the Divine Contract of Jiuli " was a manga by L.Dart.

I'm not an update tracker for comics or novels, so I can't be sure of the update time of the Spirit Contract comic. My knowledge ends in 2022, so I cannot provide the latest information. It is recommended to check the manga's official website or relevant social media channels for the latest updates.
