uncommon sense

the point was that you dont usually happen to "have" the "counterpoison" to fend off the original poison

in ai chans case though, ai chan is talking about using a specific poison in low doses to slow down another poison

in alvas case, alva is talking about a specific poison that is the literal antagonist of the other poison, and how most people dont have those poisons prepared 24/7
the problem is the momentum
most rabbits dont have enough power to tackle a goblin and wound them
even if they are thrown and pierces the flesh with their horns, the horned rabbits are likely to die from the impact, or at least suffer from a concussion

in the end, the existence of horned rabbits is biologically impractical, yet it is a "common" animal / monster nowadays, used in many novels

--but alva doesnt want do talk about these! alva wants ai chan to think new uncommon senses!
they die in the end, but not without dealing damage to the innocent humans
they are weak, but they are strong because they are seen as weak
they are being underestimated, and thats why they can win in the end 

then where are the Killer Rabbits of Caerbannog?
yep, used as a scapegoat
i believe i remember something about its origins being a fairy though... something german
how bees fly
dragons are nice, but we kinda already know about them
i will leave the details to a dragon fanatic

i want something new! 

duh it from old rpg game thoupe imo there plenty of ut on current uncommon thing

example basic thing
same language, same currency, village sorrounded by monster yet hero still can rest without bothered by nasty monster, also please hero only you can save the world

it weirder that adventure guild exist... yup really weird.... imagine enourmous time, resource, power and connection just to make such organitation recognized and accepted even private military company can't compared to guild adventurer influence~ closest we have is UN wait maybe FIFA 

Correct~! Novels focused on world building should explain this, but generic isekai novels authors usually focus more on the protagonists

As for the knights... this is not "that one country where humans grow on trees". Training a knight takes years. They are official part of the kingdom. Adventurers are the unofficial group that is basically "legal mercenaries"

Taxes are either spent wastefully by corrupted nobles and riches, or spent to nurture the kingdom. One way of doing so is by raising the knights. Other ways... i dunno
if light armor is made of stacked leathers (which is pretty good / NOT bad), then high end armor might be plate armor or gambeson 

nuu.... still not enough uncommon senses.... 

i did say it is an uncommon sense though? i wanted to focus on the "weakness" of bows despite them being the MVP of wars (as you said)
when it comes to women, their social standing was low in the past, so lady knights are only something you will see in a country with there is gender equality
this one is a meme, really
it started with one person, then two, and then... it became "common sense"
something with their constitution after reaching the second rank or something
this is not true for every story; its not a (un)common sense
never have i ever read this
in naruto they have excuses with chakra and whatnot, but i have otherwise never read novels where walking through a vertical wall is "common sense" 

Nah not pyramid scheme.  Most Chinese xianxia novels follow organizational hierarchy, likely a result of the local culture/school systems/bureaucracy while meshing together dynastic Chinese who were the hegemony of other vassal states/countries (think 14th century Ming Dynasty regularly getting tribute from Tibet).

That's why it's "uncommon sense", because these hierarchies don't translate well when it's repeatedly stacked.

e.g. MC starts out in a Tier 3 Kingdom.
He levels up, moves out to "expand his horizons" and gather better resources/power.
So he migrates to a higher level Tier 2 Kingdom that had hegemony over his Tier 3 Kingdom.
Note that the Tier 2 Kingdom usually "gifts" resources to the lower Tier 3 Kingdom in exchange for their continued subservience.
Then MC levels up, and continues moving upwards to the next Tier 1 Kingdom.
And so on.

There are usually "rules" that passively allow lower Tier kingdoms to be promoted to higher tier.  i.e. a Tier 2 Kingdom cannot deliberately suppress a Tier 3 Kingdom from advancing, even though that should be the obvious thing to do.
"Hail the King", "Martial World, "True Martial World", "Divine Throne", just to name a few. 

^ anyhow, the uncommon sense is "winged humans that can fly"

if a real one were to appear in a world without magic bs, a reasonable fact would be that they are weak as heck compared to normal humans
yep yep! thats "uncommon sense"!
(a person with human...?)
i was talking about something a little bit different, but its okay!
