The Great Strategist Sima Yi of the Adorable Dance World

Cao Cao is a homewrecker, Liu Bei is a bitch! Lu Bu is a lesbian, and the emperor is a lovesick fool! A down-and-out young man from the 21st century transmigrates to the Three Kingdoms era. He plans to use his knowledge of the future to make his mark and build a grand legacy, only to discover that many famous generals he knows by name have turned into adorable girls?! Heh heh heh, isn't that even better! Of course, if he gets too carried away out in the world and neglects the proper wife, he could find himself in a Dead End at any moment~

P.S. Since this book has a large cast of important characters, it also features a wide range of elements. Overall, it balances serious and comedic tones. The protagonist is a strategist, so the story mainly focuses on plotting behind the scenes. Except in special circumstances, he rarely goes to the front lines to show off and dominate the battlefield.

P.S. 2. Even if it's a harem novel, I think it can still be written with some brains.
