Conclusion: You guys' infantry archers were cracked. I included some unofficial histories and novels, so just read this for fun. Still feels good to be recognized by the Qing, Yuan, and Japanese pirates who were actually good at fighting back then. Feeling good that they hyped us up to matchlock level (it's like a nerd getting recognized by the school bully). Especially since nomads who mastered horse archery complimented our infantry archers, I think we've earned this K-pride moment. If there's wrong info, let me know, someone check this plz thx.
