On a stormy night at an underground auction, Shen Jin, an elite shadow assassin, vows to seize the Eye of the Deep, a gem containing clues to a weapons dealer, in order to find his missing sister. Fu Hanzhou, the head of the Fu Group, is equally determined to claim it and avenge the hijacking of his cargo ship. But just as their daggers and silver chains clash, they discover that their target has already been destroyed by a mysterious force. The Dark Web organization they are investigating turns out to be the same enemy they both have sworn to defeat.
One slips through the darkness with ghostlike agility, his blade stained with blood as he searches for family. The other controls every move with meticulous planning, his chain at his opponent’s throat as he seeks the truth. From bitter rivals to partners in battle, they face data streams in abandoned factories, arsenals in island prisons, and life-or-death pursuits across borders. Each clash deepens their bond, while bringing a greater conspiracy behind the Dark Web to light: the key to the Fu family’s old case lies in Shen Jin’s sister’s disappearance, and the cargo ship hijacking Fu Hanzhou is investigating is tied to Shen Jin’s father’s death.
When a blazing blade meets a cutting edge, will they hold each other in check or make each other stronger? They must not only tear away the Dark Web’s layers of deception, but also face the cruel choices hidden behind family ties and the truth. Where will this deadly pursuit of their enemies ultimately lead them?
