Transmigration: The Legend of the Merfolk

Dual male protagonists, sisters, don't be misled by the label. The main 0 CP is Qiao Sen & Xia Bi (cold externally but responsive to internal requests, the doting magician Gong vs. The beautiful mermaid patriarch Shou who is cold on the surface, lively, smart and loves to complain) The modern man Xia Bi came to other worlds to become the leader of the mermaid tribe and met the powerful explorer (magician) Qiao Sen to save the mermaid tribe. Sisters who are interested can consider joining the trap. Looking forward to my wife's follow-up works~ Come on, ma'am~💕

It feels pretty good, I would like to give my support, but the author didn't mark it clearly. It's a story about two male protagonists. The netizen named Suisui has compiled a more detailed one. You can read his post.
