Peng Yi, an ordinary college student who came to Hong Kong from the mainland to study, accidentally awakened the super power of "strategic deduction" - he can build accurate future deduction models in his mind and predict every move of his opponents. When the underground world of Hong Kong Island was turbulent and all forces were ready to move, he was forced to be involved in a life-and-death game.
On the surface, he is a nerdy and honest person who is inexperienced in the world; secretly, he is a "ghost trader" who makes the entire black and white parties in Hong Kong fearful. From the fights of street gangsters to the secret wars of multinational groups, from the confrontation between police and gangsters to the life and death situations in the underground boxing ring, he used incredible calculations to make all those who despised him pay a heavy price.
But Peng Yi always sticks to the bottom line: don't harm others, don't use poison, and don't hurt innocent people. He just wanted to make enough money to retire safely, but he found that he had stepped step by step into the deepest whirlpool of Hong Kong Island - behind those seemingly independent battles, there was hidden a big conspiracy that could subvert Hong Kong Island.
And there seems to be a bigger secret about his deduction ability that has yet to be unlocked...
