Oooo, the cursed Western cooking, Chinese cooking number one trope. Almost as prevalent as the Katana-is-the-ultimate-weapon or "I need rice and a bath!" tropes in a lot of isekai manga lol
minor history ting - the Yellow Turban Rebellion occurred in China, not Korea
This seems like it's gonna be a mix of Chinese and Korean mythos/history, as many of the wuxia or xianxia are wont to do
11 chapters in, and I have yet to see any reason why this manga is called inferior magic swordsman
Oh well
-edit-
Nevermind, that's answered literally in the next chapter lul
