The Northern Sovereign is very stupid. Naturally no one in their right mind would assume Shun Long concocted this pill. But for a Sovereign Realm expert like her to have no idea what pill it was, you can safely assume that an alchemist (whatever the highest grade is in the central continent is, like 2 or 3 star rank alchemist) capable of creating such a pill that was never seen before would most likely value their privacy. Honestly I’m suprised someone as old as her didn’t first ask if Jiang Tiangfeng was under a Heavenly/Dao Oath (whatever it’s called in this novel since I forgot) to even be allowed to talk about the pill or alchemist
