...if the empress dowager purged a good number of the staff to the point where there weren't that many ladies from the time in the rear palace to pass on that info... especially considering someone would need to keep making new notes to replace older ones that could get lost or damaged.
But yeah, this seems like it's part of a greater scheme
You can also add that the palace doctors that are there are no par to Ruo Men's expertise. A good example is the current doctor Maomao calls quack. It looks like they dont study or reasearch and were just branded as "palace doctors". So even if there is little information they wont pursue learning it bec they are just quacks and not passionate with their work
You have some good points! I wonder if its the Empress Regnant's intention to do that? Or is she just raging? There is a grand scheme ongoing in this manga and there is no clear motive and suspect yet,,,, empress regnant can be a good suspect
oh wow, you're right - the current doctor being a quack might be an intentional decision. It'd make it a lot easier to hide unnatural deaths if the doctors in charge has no idea what they're doing.
Wait, if Maomao's father did this before, then shouldn't the information be basic knowledge now? The fact that it isn't implies that someone deliberately erased information vital to the survival of the infants in the rear palace. That could be one of the reasons why hardly any heirs survived despite the large amount of concubines available.
