When I Traveled Back in Time to My First College Entrance Examination, I Directly Reduced the Dimensions and Took the Test

A biology graduate student died suddenly and traveled back to 1978 to become a first-year high school student in a poor ravine in southern Sichuan. When the loudspeaker sounded "Resumption of College Entrance Examination", he knew that the opportunity had come. After finishing the college entrance examination paper in thirty minutes, I shocked my class teacher and was admitted to Huaqing Department of Biology as the top student in the county. While others are still chewing on old textbooks, he has proposed the mechanism of DNA methylation and invented the PCR instrument, shocking the world. A poor boy supports the biological future of a country. !
