The outside world's assessment of Lü family's young master: dull-witted, martial arts fanatic, and idiot. An accident leads Lü Zhao to transmigrate into this person with a "纨绔 System." From then on, the world's view of the young master changes to: profligate, arrogant, domineering, unscrupulous, crazy, and incredibly awesome. With the "纨绔 System," Lü Zhao excels at everything: stepping on others, teasing, seducing girls, squandering wealth, and plundering. Becoming the world's number one profligate is Lü Zhao's goal. To achieve this, his martial arts prowess cannot be weak; thus, the strongest profligate is born.
