Four mathematicians who didn't know each other were invited to a mysterious party. In this mysterious room, there are some brilliant and clever mathematicians, logicians and inventors. Get together to solve the so-called mystery Only then did I find myself in a trap, and the four walls of the chamber of secrets would shrink to the middle constantly because of the function of the surrounding hydraulic devices. The atmosphere in the room suddenly became tense. Some people are impatient, some people are angry, and some people are calm on the surface and uneasy inside. With the passage of time, four well-dressed people who seem to have no connection began to slowly emerge the complex connection of thousands of extreme space movies (1 1). These famous scientists, logicians and inventors have repented one after another: Pascal, who just got a patent, Kallova, who is famous for his self-destructive lies, and Olivia, who rekindled her old love, have confessed their lives ... This is an intellectual competition against death, and there is no right to quit. After four astute mathematicians solved one problem after another with their own wisdom, they did not fall into a strange circle of problem solving, and their logic was strict, their reasoning was accurate and careful. Is it just an intellectual game painstakingly arranged by the host of the party? Or is it a trap carefully set by someone for revenge? Or is it a murder hut deliberately arranged by the "behind the scenes"? Kallova's impulsiveness and wit, Pascal's melancholy and prudence, Olivia's beauty and frankness, Greek's insidiousness and sophistication, Fermat's flickering have always kept the audience in a state of high tension. Just when everyone began to agree with one of the inferences and understood the suspense of this "shrinking cabin" a little, another kind of speculation appeared in front of you, which gave you a new reasoning impulse, just like most reasoning movies.
