There are historical references, but most of it is nonsense! 2. A slow-paced farming story, also known as The Cao Family Is One Big Happy Family. Wu and Shu are next door. This is a Three Kingdoms AU without war, so enter at your own risk. 3. The protagonist has no pairing; some side characters have BL pairings. 4. The heroine is a true little princess, but the biggest heartthrob in this story is actually Cao Cao ←_← 5. By default, Cao Cao has only five sons: Cao Ang, Cao Pi, Cao Zhang, Cao Zhi, and Cao Chong.
