Yi xue is a fictional creature, although you said this is a “arkified” version of Yi qi, I still thinks there are a little bit to much of fictional vibe in it for it to be an species under the genus of Yi.
Without mentioning its abilities, and by just looking at its sheer size from the human comparison picture, I think you can tell what I’m saying
Yi xue from the picture is probably around 200 to 300 kilos compare to irl Yi qi which was only 0.4 kilos
THAT IS AT MINIMUM 500 times bigger THAN THE REAL THING!
or maybe I’m just overreacting lol (looking at you Rhyniognatha) at least it’s not millions times bigger (literally) than it’s origin.
And again who cares anyway🤣 Its cool, and that is all it needs.
