The Ultimate Crown Prince: I Conquer the Entire Court on My Own

Reborn as a useless imperial grandson, he was made to drink by a beautiful young woman from the start?

And that woman was his fifth brother's lover!

You dare frame me, the imperial grandson? I'll stick you with a needle!

His fifth brother, sixth brother, and the chancellor were all in cahoots?

They want to harm the imperial grandson? I'll make them pay dearly!

The state treasury is empty? No problem. I know how to make salt!

Hand over the military command!

The northern barbarians won't submit?

I'll come clean: I'm invincible!
