Kung fu movie which ends by alien pierced on a pole and his blood is liquid metal? [closed]

I just remembered I saw a king-fu/martial arts movie when I was a kid (now I am 29) where the hero searches to uncover some secret and ends up accidentaly killing an alien, who looks like a human when the alien falls onto a pole.

In the ending scene, the alien's metal-like (silver, or golden) blood is escaping him and a human woman who loved him runs over and explains he was an alien and just wanted to go home on his spaceship.

There is something happening with the skies during the movie, can't really say what it was, hopefully some of you saw the movies when older and can recall more.

Any information, even if you don't know the name helps, thanks!

More details: I suspect the movie must have been from 90s, or 80s. Given its a Martial arts flick, it should be asian (not 100% sure though) and it might be a B movie.

• Genre: Primarily Action + Martial arts, plus I recall a scene where they had some non traditional equipment.
• Fame: probably B movie, or a less known one.
• Setting: I think it was set in asian city, recalling a chase in some tiny cars, like the taxis made form motorcycles. I recall a scene where the villain run away on a motorcycle(?) from two guys chasing him in such tiny car that got stuck in a street.
• Twist: I think they the hero possibly with a companion were trying to uncover something smelly that was going down in the city, discovering the "villain" at the end of movie, who turns out to be a humanoid alien, only wanting to return to home and accidentaly killing him as described above.
• Notable details: I recall something was weird with the sky of that city, something with lightning and a golden orb of some kind. The "spaceship" was in a shape of asian dragon. I think the orb might have been something the hero was trying to maybe find and get it back to where it was stolen from?

Update 2: I found a guy looking for the same movie on the internet! Here is what he says:

Good day everyone. I'm searching for a movie, I think it's from around 80's years. I do remember the plot completely but just cant find the name.

Story revolves around a mysterious silver orb, which was kept in a Buddhist temple and stolen by a group. It was kind of a worshiping object to monks. After it was stolen, a young monk somehow gets close to the crooks that stole it and eventually they find the person who needed that orb. In the end it is revealed that orb is in fact a key to the alien ship and the mastermind is and alien himself stuck on earth for some reason. They almost kill him towards the end but he manages to fly away. Ship looks like a dragon from afar.

Plot takes place mostly in Tibet (I think) and few locations are in desert.

If I do recall, movie is in Korean, or at least some Asian language"
