In the shadow of the world, there exists an agent organization called "The Abyss". Ling Ye, codenamed "Zero", is the sharpest blade in the abyss and the perfect pretender walking in the darkness. Handsome, deadly, and skilled in all the arts of murder and deception. When a chip carrying the secrets of "Pandora" accidentally falls into a bustling city, all forces take action. Ling Ye was ordered to sneak in with only one goal: to recapture the chip and erase all traces before the storm came. But this time, he faces not only a vicious enemy, but also an unpredictable human heart, and a past that he has deliberately sealed away. In this maze of lies, desire and betrayal, can he, code-named "Zero", maintain an absolute zero level of emotion?
