Liu Junjie is a dying genius who is ready to do everything he can to stop his suffering. He has the brain of a mastermind but the tact of a monkey. He can maneuveur a countably infinite sequence of operations using only his mind. He is a citizen of the Slums of Caihong City and lives off the petty bargaining he does at Renmin Square, one of the few places that he can access by wheelchair.

His proposal is accepted by Furui City and he has to present it before the Committee in seven days. However, there is one last piece of the puzzle to Liu Junjie's Supertask: a glitch that he is unable to solve...
