The Great Tang's Most Filial Son: From the Start, I Snatched Wu Cairen

Ji Han accidentally transmigrates to the Tang Dynasty and becomes Li Chengqian, the crown prince destined to rebel and die a horrible death. He also gets bound to the “Great Tang’s Number One Filial Son System.” All he has to do is use filial piety as an excuse to mess with his father. The angrier he makes Li Shimin, the more generous his System rewards! At the selection ceremony for the imperial consorts, Li Chengqian pulls the future empress Wu Meiniang into his arms, his expression righteous and resolute. “Father, this woman’s fate clashes with yours. She is destined to overthrow the Tang and rule in her own right!” “For the sake of the Tang realm, I would rather bear the shame of stealing your beloved than let you fall into this calamity of worldly desire!” Li Shimin is so furious he nearly suffers a heart attack. Pointing at the door, he curses his rebellious son. 【Ding! The Host has displayed unparalleled filial devotion. Reward: Eighteen Riders of Yanyun, plans for red-coated cannons!】 From then on, Li Chengqian goes all out in his quest to mess with his father. He beats up Li Tai and tricks Zhangsun Wuji, while the entire court can’t help imagining hidden meanings in everything he does. Even the retired emperor Li Yuan takes a cane to Li Er, berating him for failing to understand the crown prince’s good intentions. Three years later, as Li Shimin looks at the red-coated cannons lined up outside the Eastern Palace, he clutches the imperial seal and begs through tears, “Chengqian, the throne is yours. Just please stop being filial!”
