Great Tang: I Keep Causing Trouble, and Li Er Eavesdrops Until He Breaks

Li Yin transmigrates into the body of the Tang Dynasty's sixth prince, bringing a military-industrial technology database with him. Hoping to stay out of court politics, he acts like a fool at every court session and begs for a fief in Lingnan so he can pursue technological development.

But who could have expected that the legendary Emperor Li Shimin would awaken the ability to read minds!

On the surface, Li Yin wails, “Your son deserves a thousand deaths. I beg Father to send me to the frontier!”

But inside, he's ecstatic: [Once I get to Lingnan, far from the emperor's reach, I'll have rifles and cannons in less than five years. Then I can become the Pirate King. How awesome would that be?]

Li Shimin's eyelids twitch as he listens.

You want to run off and build cannons? The imperial treasury is empty right now!

The next day, Li Shimin announces at court, “The sixth prince is obedient and filial, and has pleased me greatly. I grant him a hundred qing of good farmland and a hundred Imperial Guards. He will stay here in Chang'an and serve as a prince!”

What's more, Li Er keeps dropping by the princes' residence to freeload on his son's inner thoughts, claiming as his own the strategies and technology Li Yin grumbles about in his head.

Watching his father drop by for free meals every day, Li Yin is close to tears. “This isn't how the Tang Dynasty story is supposed to go! So who's the transmigrator here?”
