Aramintai

She basically has a new body now. Perhaps all soul shifter marks, along with petrification ones disappeared because of the transformation. And since body and soul are identical in appearance/in harmony now she's can't run wild anymore.

He's yet another shady selfish character it seems.

Probably.

Looks like it.

#2 already happened in part 1. U sure they gonna repeat same ending?

Yea, JBY's soul is dead and gone. Only her body remains, but it was transformed into Naksu's appearance. And apparently it was her body with innate divine powers that kept Naksu in check.
For details how Naksu was revived watch episode 2.

Aside from Jin Mu and his cronies apparently nobody else knows.

He had to use a soul ejector to force the king to switch bodies back. And since he performed aos, Jang Kang became a soul shifter even after returning back to his own body.

Same, I’m bad with remembering strangers faces 😅

She doesn't look like an assassin and it's been 3 years, facial memory can get all fuzzy. But I'm sure many people will start remembering, let's keep watching.

Well, it’s not exactly her body now., the transformation may still not be 100% complete. The eyebrows color is also different.
But irl, I don’t think the production team cared enough about actress’s slight change of style.

Yea, the king did the deed, but the body wasn’t his.

Watch episode 2, it gets explained how and what happened to her.

It's you who should stop. The ones who said Uk was king's son were doing it because Jang Kang said it, they had no other evidence other than that. And king knew nothing, but he wanted to believe, because he was about to die. And Jang Kang did what he did to protect his son from being killed by the current king. Uk being the son of the late king means he has more rights to the throne than the current family. But what evidence is there to support Uk got his genes from the late king? None. On the contrary, late king wasn't even a mage. And that Uk was born on the day of the King's star doesn't mean the king was his father, it only means he was conceived at the right day. It was even mentioned that many people can be born under the same star and that royal family would find and kill any that were born outside of it.

Evidence in part 2 is concrete though. Bu-Yeon's soul is gone, but her body, her genes are still exhibiting her magical abilities. It suggests the soul is not a contributing factor to it, after all.

You can't dismiss a hard observational evidence and take an unproven anecdotal evidence as fact. It goes against scientific method. But I guess you weren't taught about that at school and believe in any kind of bs people say for their own benefit.

I guess unless somebody finds a way to reverse her transformation she won’t even run wild now. And maybe all the marks are gone because it is basically a new body.

The point is, and master Lee said it clearly, for a soul shifter to not run wild a body and soul must be in harmony, identical to soul's appearance. That's how he reversed her petrification process.

Soul shifters main problem is that the new body they inhabit isnt identical to their original one and it starts leaking energy. Naksu got lucky with Bu-Yeon's body because it locked her energy from coming out. But now since it's identical to her soul's appearance, she won't leak energy now and won't run wild anymore. All soul shifter marks are also gone from her body now, Uk even checked her eyes.
But if you really want to believe she's in danger of running wild, keep stressing out about it, I don't care. I got a clear answer that she doesn't have to worry about it anymore.

Some kind of monster. They apparently exist there in Daeho as well. They are frequently attracted to Uk now because of the ice stone. He seems to be dispatching them on a regular basis, even his houshold servants are not startled anymore. I'd say that creature is some sort of vodyanoy or whatever equivalent they have in SK.

Yes, they were both in Bu-Yeon's body. But the mark was in her eyes. Uk even checked whether new Naksu still has it, which she doesn't. Because she's no longer a soul shifter - master Lee used her energy to transform Bu-Yeon's body to take shape of Naksu's soul appearance. Her body and soul are now identical and in harmony. Watch episode 2 again where master Lee resurrects her if you're still confused.

It's just what they believe. But part 2 evidence says otherwise.

Naksu did perform aos, but got trapped inside Bu-Yeon's priestess body. Why the ef it was Bu-Yeon and not the random girl Naksu chose will probably never be explained now. Maybe Bu-Yeon interfered deliberately, maybe she got sucked into it by a coincidence, or her body was a better magnet for the spell.
