After being dumped by his girlfriend and publicly fired by his boss in front of everyone, genius programmer Leo is reduced to working as a network administrator at a small internet café. Everyone sees him as a failure—none of them knowing that he is the long-missing top-tier hacker, and the true creator of a multi-billion-dollar AI technology. When international hackers launch attacks and corporate giants fight over patent rights, Leo turns the tide time and again. As his true identity comes to light, his betraying ex-girlfriend is consumed by regret, while both a wealthy heiress and a beautiful CEO find themselves falling for him. Trampled by everyone, he rises to the pinnacle of a tech empire—and makes everyone who looked down on him pay the price.
