In the fireworks at the Huxi Pier, the swords and shadows of the rivers and lakes are hidden. Five brothers from lower-class backgrounds, unable to bear the oppression of the Green Snake Gang, formed an alliance with the pigeon blood dragon pattern and swore to form the Five Dragons Association. The five dragon patterns coincided with the five elements. They showed blood when exposed to heat and resonated as an early warning, which became the mysterious confidence to enter the magical city.
They abide by the iron rule of "do not bully the old and the weak, do not engage in drug gambling, and do not kill innocent people indiscriminately". They first showed their talents in the dock fight, frightened powerful enemies at the negotiation table, used their wisdom to bring down the backers of the collusion between officials and gangsters, and finally cleared up the chaos in the west of Shanghai with their blood and let the dragon flag fly all over this land of fireworks. Along the way, there is the warm friendship of brothers, Su Qing's forbearance and resourcefulness to avenge her father, and the mysterious prophecy of the reclusive old man that "the dragon pattern will appear in three years, and the world will change."
When the Five Dragons Club has gained a foothold, the tranquility in the west of Shanghai has not yet warmed up, but Longxing Society, the leading society entrenched in the Magic City, has cast a wary eye. The secrets of the five dragon patterns, the hidden origins of the five people, and the upcoming storm in the rivers and lakes, all in the neon lights and ancient temples along the Huangpu River, kick off a three-year struggle for hegemony in the magical city. This is a passionate epic about the counterattack of the bottom, and it is also a chivalrous song where the traditional world collides with the modern magic city.
