I recommend My Wife is Battle Lady to you. This light novel was about the male protagonist Fang Ran developing his ambition and black technology in the magic world, but he was unexpectedly captured by the enemy's main leader, Battle Lady. From then on, the two of them began a wonderful journey. The female lead is strong, the male lead is skilled, and the plot is compact and interesting. I believe you will love it. I hope you like my recommendation, Mwah ~๐
