Sorry.. I can't remember this certain character also idk which forum i can ask this so i pick here. So there is a side character named Elder Zi Hou at ch236, who is he? When did he come from? I can't remember anything about him help
I believe that's the now deceased Grandmaster Apothecary that Su Luo found the workshop of very early in the story. The main thing she gains from his workshop is his cauldron and some pill recipes/manuals. Otherwise, she's never met him before.
Yes. Chapter 95 onwards. While on the run from Li Yaoyao's entourage, Su Lou stumbled on a cave containing Zi Hou's legendary medical cauldron and lost recipies, thus giving her alchemy studies a strong foundation. Well done, Li Yaoyao.
