Was the manga of the agent of the underworld based on that novel?

Of course! I recommend you a secret agent underworld novel," Secret Agent Wife in the Underworld." This novel was written by Yuyue. It told the story of an agent's wife who transmigrated to the side of a gang leader. The female lead was a mysterious and charming agent, while the male lead was a manly and super handsome underworld boss. The fate between the two slowly unfolded in the dark world. The plot was compact and exciting. It was definitely a gangster novel that could not be missed. I hope you like it!

Sure, Underworld has its roots in a comic. The comic provided the initial framework and concepts that were then transformed and brought to life on the big screen. Some aspects were modified for better visual and narrative effects.

I recommend "Flower Protector" to you. This novel is an urban supernatural novel written by the author, Long Zhu. The story was about a wandering young man whose family was destroyed. He stimulated the inheritance of unparalleled cultivation and began to make a name for himself in the city. He rose to the top, and the school belle, the beautiful president, the police beauty, and the underworld princess were overwhelmed. I hope you like this fairy's recommendation. Muah ~😗
