Yuan Kewen, one of the four young masters of the Republic of China, was unruly and talented, but he died suddenly in his prime. No one knows that the soul of an anti-drug elite from a hundred years later is quietly awakening at this moment. Faced with the desperate situation of his family's decline and powerful enemies surrounding him, he hid his edge and hid behind the scenes. Behind the neon lights of the dance hall, there are culverts through which harmful things quietly circulate; beneath the peaceful singing and dancing in the concession, there is a life-and-death struggle between forces from all sides. He dealt with youth gangs, warlords, and foreigners, using his pen as a gun and strategy as a blade. When the woman he loves is also involved in the whirlpool, and when it is discovered that there is a more terrifying shadow hidden behind the conspiracy to poison the compatriots... The disguised romantic boy finally takes off his shell, revealing his iron bones. On this road back from hell, he vowed to kill all the monsters, clear the turbid current, and strive for a clean future for the people he loves and for this land.
