>>57035831st: Depends since evolution can be very dependent on environmental influences and recent doings. But you'll be able to reach all of the ones available now with proper planning/ setting
2nd: Yes, eventually, but it'll be harder
>>5703582 (Correct)>>5703591 (Yes, the name is very apt as you correctly guess)>>5703598 (it does have some pretty wacky abilities, but I don't wanna spoil too much) 3rd: Special. Huan has supreme Yin physique, meaning her body is naturally amazingly yin aligned but without being purely yin like Monu's pure yin physique is (which among other things, basically locks her to Yin techniques and styles, and causes her to have a deficiency of Yang), so she can use Yang spells and stuff, but her bonuses are weighed heavily towards Yin with it and her ghostly half spiritual roots
Eclipsed Yang physique, to be blunt, is practically unheard of. Mostly because it is a physique that requires another to actually become active or be inherited. So even if someone has it, they probably won't know they have it.
And its called Eclipsed Yang physique because it, both in function and appearance, resembles a total solar eclipse. The yang energies forming a halo around the black sphere of Yin, and switching from the usual conflict of Yin and Yang to how dark and light and the various other aspects of the two compliment each other rather than oppose. Basically, Eclipsed Yang is the white dot in Supreme Yin, but that does not mean its weaker or lesser than it, and it will boost her Yang aligned abilities+ resistances
Which is like how Huan already uses her Pure Yin Ghostly Qi and her Pure Yang Blood Qi together, and her body could adapt the rare/ unusual eclipsed yang physique because she makes a habit of slipping in between boundaries. Like how she can befriend and earn the loyalty of people all across the alignment chart. If that makes sense
The best way I can describe it is how I did early, Eclipsed Yang physique embodies the total solar eclipse, which means it has some pretty mysterious, esoteric and odd abilities, since most cultivation clans aim for PURE YANG or PURE YIN with eugenics and physiques occurring naturally (In random births I mean, like high quality spiritual roots or special organs like Mermaid lungs are pretty rare). Like Huan had to make her physique supreme Yin when she, ya know, turned into a puddle.
There are a lot of variations and types of physiques
Also trying to explain this reminds me of how spooky Huanliuxue's aura looks and feels
4th: Yuyi has a bloodline due to being infested with a lot of Primordial beast essence, similar to the other unlucky souls who were affected by the beast roar, which activated it inside her and them. Basically the bloodline creation is codify Huanliuxue's legacy and expressing it as power and will. Yuyi is the start of a cat blooded bloodline because of Huan, even if she removed the more obvious signs of it from her
5th: Unless I drink too much tonight, yes.
