The night at Nanwan Pier hides the deepest conspiracy in the world. Lu Siping, the third son of the Lu Family Association, died tragically, and the scene pointed to the Su family gang. However, Lu Yi, the eldest son of the Lu family, pried open the coffin, only to see an empty coffin and the glass beads of his sister Lu Yao. The truth about "the Su family's silence" suddenly collapsed.
Holding a ghost-headed sword engraved with "loyalty", Lu Yi and his old men wanted to find the real murderer and revive the family, but they ran into the wolfish ambition of Su Zhenxiang, the leader of the Su Clan, to monopolize opium. Su Jin, the silent hawker in front of the cigarette stall, is actually the daughter of the Su family. She betrayed the gang and used lancets and darts as blades to stand side by side with Lu Yi in assassination and redemption; Lu Xu, who lurked in the Green Snake Gang, was trapped in the undercover quagmire by family ties; Su Qing, who lived in seclusion in the teahouse, hid her guilt and tried her best to stop Su Zhenxiang's madness.
Four major mysteries are intertwined: the suspicion surrounding Lu Siping's death, the blood and tears of Su Mei's undercover agent, the manipulation behind Lu Yao's paranoia, and the final undercover agent hiding in the dark. No one is purely good. There is a gray line under Lu Zhen's "righteous bandit" aura; no one is absolutely evil. Su Zhenxiang's cruelty stems from old grudges, and Lu Yao's murder was just because he was bewitched.
In the dock fire, the slum chase, the black market melee, and the duel between the silver snake and the golden tiger, Lu Yi and Su Jin, with the intention of "bringing order to chaos", vowed to destroy the opium system and restore order in the world of "no opium, no killing of the old and the weak".
Revenge ended, the opium ship was burned, Su Zhenxiang was exiled, Lu Yao went away to heal, and the Lu family gave up their hegemony and became the guardian of order. But Su Zhenxiang's secret words before leaving, and the mysterious jade pendant among Su Mei's relics, still leave a lasting impression on Shen Yuan's truth, and the shadow of the rivers and lakes has never dissipated.
