(SOLVED) Forgot the Name of Obscure Asian Movie! 80s Era

Hello all!

I'll try to give as much details as possible!

I'm not sure what year era it was from, maybe late 70s to 80s? It's definitely older than 90s.

Details:

I remember that there was an evil gang where they kidnapped a woman and she was brought to some kind of tall building, they were on the top floor. And the gang had their own captive (woman as well), not sure what her role was. But, the recently kidnapped woman wouldn't tell anything, so in order to prevent herself from being tortured for info, she used some kind of magic to cut her own head off, it was like a blue streak line with her hand "slicing" her neck without actually touching it.

The gang was surprised, but didn't care because that's why they had their own woman in the event of this, so her head was cut off and used the kidnapped woman's head to put on the woman. Now that I'm typing this out, why couldn't they just put it back on the kidnapped woman's body? :P

But anyways, yeah. And I just remembered, the woman tried to jump out of the building and was prepared to meet her end by closing her eyes right before the rocks on the bottom in a slow motion scene, but a member of the gang flew to catch her, and then yeah, she proceeded to cut her head off herself.

That's one of the two scenes I remember.

And now the second scene and I believe it was the ending, um. It was two people who were in love, I believe, they were in some kind of hellscape setting, with a bunch of fires and they were both propped up on the crosses, as if they were going to be crucified. But also they seems to have accepted their fate? Like they were happy to die together.

I don't remember the gang very much, too, unfortunately. I mean I do vaguely remember that there was a chunky man. And another man with some kind of conical bamboo hat. It was a bunch of raggedy misfits, evil-looking.

The time period of that movie was most likely to be way before 1800s. Or at least medieval setting, nothing industrial or technological.

It was also fantasy, like there was a lot of magic. Insane movements and fighting skills.

That's all I can remember, sorry and thank you in advance if you know the title of the movie! I loved this movie and it's been decades since I've seen it, the first scene has been replaying in my mind! :)
