As the Crown Prince Li, I Purge the Court from the Start

【Go on, leave. Don't read this. I'm begging you. I know my writing isn't good.】 Alternate history + System + mindless power fantasy I transmigrated, but ended up as Liu Ju, the Crown Prince Li? What? Jiang Chong will frame me and get me killed three years from now? I think there's still time to save myself. Wait, don't I have a System? I can summon an army soldier every second. What have I got to fear? Guards! Jiang Chong is rebelling. Come with me to purge the court of traitors. All under Heaven is the emperor's land, and all who live within its borders are his subjects. I will make the Han Dynasty great again.
