As the top intelligence dealer codenamed "Nightingale" in the dark web world, Shi Ying never does business at a loss. She is mysterious and expensive. A string of codes can subvert the stock price of a consortium, and one sentence can determine the outcome of a business war. Until she kicked an iron plate - the rumored business emperor who was decisive and ruthless, Fu Jing. In their first fight, she hacked into Fu Jing's internal system, stole a secret, and resold it for a sky-high price. Fu Jing did not call the police, but found it along the Internet cable, and attached a blank check and a sentence: "I will buy you." Shi Ying: "?" Fu Jing: "Be my exclusive intelligence source, you decide the price. I am responsible for providing shelter, and you are responsible for clearing the way for me." A dangerous alliance in which each takes what it needs and may backstab the other at any time is concluded. Shi Ying thought this was just a pure transaction. She provided information and he paid. The two were the best partners walking on the edge of a knife. But gradually, things started to go wrong. She was attacked late at night, and Fu Jing's bodyguard team arrived faster than the police; she casually complained about the cumbersome procedures of a certain company, and the company was acquired by the Fu Group the next day; she was dug up by her opponent, and Fu Jing directly used thunderous means to uproot the opponent, showing more concern than she herself. Until one day, Fu Jing blocked her in a corner, with dark and unclear emotions surging in his deep eyes. "Miss Nightingale," his voice was low, with a hint of dangerous temptation, "The information you sold me never seemed to include... Your heart." Shi Ying:! ! ! Boss, we are dangerous allies, not dangerous lovers!
