Holding the Emperor System in Hand, He Was a Puppet at the Beginning

[Alternate history + Protagonist pretending to be a pig and eating a tiger + The strongest system + Focusing on making money] Zhao Qingan traveled to the Daluo Dynasty and became King Lu who was preparing to become the emperor. I originally thought that all the hardships in this life would finally come to an end, but who knew it was a scam from the beginning. Because there were four other kings who also received the title of emperor, and they were also the great contributors to quelling the Zhou rebellion. After knowing the reason, he simply messed it up, but he didn't expect that he accidentally became the emperor because of watching the Romance of the Three Kingdoms, and he also came with the most powerful system. I originally thought that I would finally have a chance to be a ridiculous emperor who only cares about enjoyment for once in my life, but unexpectedly, I was told by the powerful officials that I would earn five million taels of silver in three months, or else I would be kicked out of my life. Hum, just make money, let's see how I can not only earn five million taels of silver but also kill powerful officials in three months.
