A new imperial examination route that relied entirely on diligent farming, practical reading and observing reality to improve production and accumulate knowledge. The protagonist does not have hyperamnesia, does not test the spirit of possession, and only has a boring "grid recording method" to summarize the rules of the eight-legged essay, compile teaching materials, and turn the profits from new crops and new farm tools into "study aid fields" to support poor scholars in their studies. Every step is calculated, there are no sudden insights, just repeated failures and corrections.
