In the Tang Dynasty, Favoritism Pays Back a Thousandfold

I transmigrated as Li Chengqian, the tragic, beautiful crown prince, and bound myself to a System that returned rewards a thousandfold whenever Li Er showed favoritism to another prince. From then on, Li Chengqian set out to drive Li Er up the wall. The more Li Er lost his temper, broke down, and played favorites, the more rewards the protagonist received. In the end, Li Chengqian finally staged his own version of the Xuanwu Gate succession. Li Er: “Chengqian, Qingque is heavy with child and has trouble walking. I’ve specially allowed him to ride in a sedan chair into the palace. What do you say to that?” Ding! Li Shimin’s favoritism detected. Thousandfold return reward: Host’s leg condition cured! Li Er: “Chengqian, I specially permitted Qingque to open an academy. You’re the crown prince. How can you open one too?” Ding! Li Shimin’s favoritism detected. Thousandfold return reward: Host gains access to the Shadow Network. Li Er: “What’s wrong with giving your fourth brother a little money? As crown prince, you should live frugally!” Ding! Li Shimin’s favoritism detected. Thousandfold return reward: Host receives 100 tons of gold. Li Er: “Your fourth brother has only hired a few more idle mouths. What’s the problem?” Ding! Li Shimin’s favoritism detected. Thousandfold return reward: Host receives three thousand death warriors!
