Great Tang: Li Er Discovered My True Identity as a Master from the Start

Li Heng transmigrates to the second year of the Zhenguan era in the Tang Dynasty and gets bound to a sign-in System. In a year of drought and disaster for the Tang, his life is quite comfortable thanks to the System.

"Son, some people say the severe drought across the land is retribution for the emperor's sins. What do you think?"

"That's nonsense. It's just a natural disaster."

"Then what do you think of the current emperor killing his brother and forcing his father to abdicate?"

"How else would you look at it? Lying in bed, of course."
