I Became an Emperor with an Intellectual Disability, So I Played the Fool to Save the Southern Song

Well, would you look at that!

I've transmigrated,

into Zhao Qi, also known as Song Duzong, the last adult emperor of the Southern Song, infamous in the history books for favoring thirty consorts in a single night.

Within, there is the notorious traitor Jia Sidao, as infamous as the Wei Zhongxian next door.

Without, the world's strongest Mongol cavalry eyes us hungrily.

And, to make matters worse, the emperor is intellectually disabled!

I originally planned to lie flat and enjoy the debauched (crossed out) carefree life I'd never even dared dream of in my previous life,

but somehow, by pretending to be insane and foolish, I accidentally extended the Southern Song's life by a hundred years!
