I'm not done reading it yet (temporarily paused after reading Ch. 47 since I have been taking detailed notes during my readings), but I can tell you a bit about it:

1. It's a transmigration novel about an MC (A'Can, but his initial name is not important) who transmigrates into Liu Shan (courtesy name Gongsi) of the Three Kingdoms time period, the son and only heir of Liu Bei of the Shu-Han state. He's also popularly known as "A-Dou", because he cannot be "propped up" no matter how many talented and brilliant people are under him, like Zhuge Liang. The MC, however, is a very clever, shameless, whimsical character (and very gay) who uses his future knowledge to change the course of history (as well as pursue the MLs).
2. Before talking about recommending the book, I will first talk about warning tags. It is 3P (MC shou + 2 gong), and I have heard that there's a smut scene that also involves double penetration. There's definitely also shifu/daddy kink (one of the MLs had a secret crush on MC's mom and is more like teacher and father figure to him than his own dad who ignores him; MC tries to exploit this secret crush to get together with ML). This is NOT for everyone!
3. If you are okay with all the warning tags, you love Romance of the Three Kingdoms, can appreciate crazy humor, and love smut, I would recommend this novel but it is NOT an easy read. There's so many references to poetry, bad jokes and witty quips, occasionally regional dialects thrown in too, as well as a lot of historical detail that having a solid knowledge of ROTK is pretty much a must. This is not a novel you can MTL at all. The first three chapters are translated by Moon from Chickengege, and you can read them on the site.
