You Are Asked to Deliver Food and You Become a National Academician?

[Easy]+[Academic Master]+[Contrast]+[Delivery Guy]+[Stingy Protagonist]+[No CP] Because his family was poor, 16-year-old Su Bai dropped out of school and put on a yellow vest to become an errand delivery boy. Late that night. Because he was stuck on the problem of the century, the dean of the Department of Mathematics at Peking University ordered a stewed chicken out of desperation and went crazy in the note: "Whoever can help me solve this partial differential equation, I will give you a reward of 2,000 yuan!" Twenty minutes later. Su Bai rushed into the laboratory with the takeout, grabbed the pen from the professor's hand, and scrawled down the formula on the lunch box. "Good guy!" "You said you ordered takeout just to ask me about partial differential equations?" "Two thousand yuan to reward Ma Liu, don't delay my delivery of the next order!" Looking at the perfect critical line proof of the Riemann Hypothesis on the lunch box, the department chair plopped down and knelt down. What the hell is this a delivery guy? !
