Originally in the strawberry world, Lin is as ordinary as every one of us, even a little depressed. He studied philosophy and was an intern political teacher in his senior year. He was arranged by the director for a charitable blind date. His father, Lao Lin, a former mathematical genius, was diagnosed with Alzheimer's disease, and would slowly forget many things about himself. There is also a male god in the department of mathematics who has secretly loved him for many years and doesn't even know it. He finally caught his attention, but he saw the gap because of the NP problem of P.
I got three cheating opportunities to go to the cheese world because of a mysterious recipe. Lin traveled back and forth between strawberry world and cheese world three times. For the first time, I met Pei Zhi and other small partners in the cheese world, participated in the Olympic Mathematical Training, got to know Lao Lin and asked him to help them learn mathematics. I successfully obtained the qualification to enter a junior high school and returned to the strawberry world to decide to take the postgraduate entrance examination in mathematics.
