Lu Yixuan, heir to the Prince of Zhenbei, is sent to the capital as a hostage. Everyone there thinks he is a profligate playboy who does nothing but throw money around. No one knows that he has a spend-to-earn System: the more he pours money into the military, government, public welfare, and his plans, the more cashback points he earns. The more it looks like he is wasting money, the greater the return.
He spends lavishly to escape deadly traps and throws fortunes into raising a private army. From the mire of the capital to the battlefields of the northern frontier, he rises over the corpses of noble families and princes. He marches south to put down the rebellion and settles accounts with the court. At last, the playboy heir everyone once looked down on takes the throne and becomes emperor.
