Great Tang: I Get Stronger by Messing with My Dad, and Li Er Is Stunned

His soul transmigrates into the Tang Dynasty, where he becomes Li Shimin's favorite fourth son, Li Tai. He plans to head to his fiefdom and coast through life, but unexpectedly awakens a System designed to make trouble for his father. If that's how it is, then he can only apologize to his old man. No cultivation, no palace intrigue, no fight for the throne. He just lies back and becomes emperor. As long as he sabotages Li Shimin, annoys him, talks back to him, or undermines him, he can earn points, draw divine prizes, and trade them for advanced technology, miracle medicines, divine weapons, and knowledge from the future! Li Shimin praises me for being well-behaved? I flip the table on the spot: Father, your policies are no good! Li Shimin wants to name me Crown Prince? I turn around and urge him to name Li Zhi instead: Your son only wants to make money and develop technology! The whole court kneels and fawns over the wise emperor? I expose his embarrassing past in front of everyone: I haven't even told them what you got up to back then, Father! Li Shimin: You rebellious brat! What are you trying to do?! Li Tai (quietly checking the System panel): Nothing much. I just want to mess with you a little more. What can I say? You're my dear old dad. From talking back to the emperor to changing the fate of the empire, from giving his father trouble to reshaping the Tang against all odds, others rise to power on their fathers' coattails. I make a god out of myself by messing with mine! As I keep giving this Tang empire trouble, it somehow takes off a thousand years ahead of schedule! Li Tai: Father, for the sake of the Tang Empire and all its people, do bear with me. You'll get used to me messing with you!
