Aramintai

Cho Yeong is Naksu's real name given at birth. Her father was Cho Chung, a constellation mage.
Naksu is just her professional nickname as an assassin, some wordplay on falling water and falling heads.

Probably because the ending turned into classical makjang bs. But it's still very good overall. Up until episode 8 included - just stellar. Just keep in mind that 3 sisters characters there were made flawed un purpose.

Here are some 2019-2022 ones I gave high ratings:
Kingdom (2 seasons +1 special)
Mr. Queen
Touch Your Heart
Mad For Each Other
Squid Game
Vincenzo
Tomorrow
A Business Proposal
Crazy Love
Extraordinary Attorney Woo
Gaus Electronics
Little Women
May It Please The Court

Of course that's just personal opinion. There are many more, like popular Goblin, What's Wrong With Secretary Kim?, Crash Landing On You, It's Okay to Not Be Okay, Flower of Evil, etc. But I found them grossly overrated due to some major flaws, so I can't recommend them without reservations.

I dunno, depending on how many you've watched already I can recommend some from yesteryears. Narrowing down genre would also help.

Of the ongoing ones? The Forbidden Marriage.
It's very silly, but watchable.

1. There are no doors Uk can't open because of the the ice stone. Furthermore, the portal for the turtle was opened by JSR's soul from the inside. She summoned him through the jade stone to help save Naksu.
Jin Mu and Cheonbughwan mages know how to open Gwido. Though Jin Mu was lured inside by JSR/Naksu with a glint of the ice stone. The Queen and her nephew asked one of the Cheonbughwan mages how to enter.
2. Jin Mu had all the mage families leaders along with him, powerful mages all.
3. Closing the door wouldn't have saved everyone from the fire bird - Jin Mu could have released it inside if he got trapped, blowing up Jinyowon with it and releasing all the other relics. Jinyowon is like a working nuclear reactor - can't disturb it, or meltdown will occur.
Also, Jin Mu is from Jin clan - he knows what's where in the vault.

The truth about the bells is exposed in later episodes and is told to Naksu by Yul. And she already knew Jin Mu used her and was responsible for her becoming an orphan since part 1.

There was a discussion about it below. He will still die of old age, just like master Lee will too.

Uncanny Counter is sooo bad and boring, I regret wasting time on it. One of those overhyped dramas. And he basically plays Park Jin there again - slow witted slowpoke. I'm starting to get the impression that it's just how actor is in general.
And they've wasted KSJ talent there, she can do much better than just keep a tired, sour face all the time and fighting.
If you want something like it, better watch Tomorrow.

Seems like divine magic is innate to the body. How much of it is of JSR and how much of it is of just mama Jin's daughter, JBY, is unclear. The show ended before we got to learn more about it.

She won't. She's back to how it was with Mu-Deok - JBY's body protects her from running wild and now there's no Jin Mu with his bells to threaten her life.

Not the fire bird, but it was said that only priestesses can perform the rain ritual to stop the draught. Which fire bird can cause for real.
And ice stones are subproduct of said ritual.

I dislike when characters in dramas don't check whether they've actually killed someone. Naksu should have finished off Jin Mu instead of letting him wiggle his way out again.

Furthermore, that whole fire bird summoning plot was full of plot holes.
First they wanted to fake out the drought to convince the populace and force Jin priestesses to perform the rain ritual, that is contained in Jinyowon, for more ice stones.
Then they decided they'll just steal the fire bird inside Jinyowon and cause a real drought.
Then they retconned the previously established lore that it had to be priestesses that can perform the ritual or that it was in Jinyowon - in the end Jin Mu said he had it ready and can perform it himself 🤦‍♂️.
And was the real drought even needed to perform the rain ritual? Didn't seem so in the beginning. Which means he could have performed it at his leisure any time.

They were total dumbasses for grossly underestimating his powers. He's the most op mage with unfathomable powers and yet they threw caution to the wind and recklessly decided to openly raid Jinyowon and summon fiery apocalypsis on Daeho. Did they really think he'd sit this one out?
I really thought Jin Mu was smarter than that, but he got intellectually dumbed down along with rest of the characters in part 2.

I think op meant to say that the villains died like total dumbasses all at once.

Yea, that whole old soul from the ice stone complicated plot was nicely done. And it's something people here even guessed at earlier.
The only smudge on it is that it's still unclear why they lied Naksu'd disappear after she regains her memories or how master Lee even knew about it, considering he only started speculating that it's JSR's soul with a plan much later.

The most useless character in all AoS. They could have cut her out and nothing would be lost.

The body belonged to mama Jin's dead baby with no soul. The soul came from the ice stone that Jang Kang used to help her give birth to that baby. The soul belonged to Jin Seol Ran, Jin clan founder from 200 years ago, who decided to stay inside the ice stone to protect it as she foresaw the future where it will be misused again.
So the body belongs to Jin Bu-Yeon with the soul being Jin Seol Ran. And then Naksu got stuck inside that body as well. In the end Jin Seol Ran graciosly left Naksu Jin Bu-Yeon's body and disappeared herself after fullfilling her duty.

Did he? Or was it the MVP turtle?

I checked it - episode 8 around 19th minute.
