Winter, 1937, on the eve of Jin City’s fall. Huo Yanxiao, the eldest son of the Green Gang's Huo family, is fighting alone and caught between the Japanese military police and a traitor within his own family.
The Huo family's illegitimate son, Huo Yanshen, returns after vanishing for three years, carrying the scholarly air of a man educated overseas and the identity of a top agent codenamed “Abyss.”
The world knows him only as a bookish, useless scholar. They don't know that in his eyes, the world has long since become a web of precise trajectories and fatal weaknesses.
“Big Brother, your aim is too slow.”
In this chaotic age, he will be the Huo family's sharpest hidden blade.
