I don’t think the kidnapping at the airport was part of any scheme by Lo Pan. I think that was an independent operation by the Lords of Death - kidnapping fresh-off-the-plane Chinese girls, and selling them to the brothel. The fact that one happened to have green eyes was accidental.
Apparently, not just any green eyed girl would do - there’s that whole ritual thing where their eyes go all white and they float around holding swords improperly. So there’s some other element they need besides just the eyes. I’m guessing that Lo Pan probably tried a bunch of white girls in his little ritual, and they kept failing, so he gave up on them, figuring only a proper Chinese girl would do. He is, after all, thousands of years old, and you know how racist some old people can be.
Easiest answer here is that they flat don’t give a shit which mortals are on their “team.”
But, it’s possible that it’s retaliation for the kidnapping at the airport. This is pretty fanwanky, but bear with me.
The kidnapping at the airport wasn’t orchestrated by Lo Pan. It’s just a side gig the Lords of Death have going - kidnapping girls fresh off the airplane from China, and selling them to the brothels. It’s pure chance that they happen to grab Miao Yin. They weren’t targeting her specifically. The brothel itself isn’t part of Lo Pan’s criminal network. It belongs to an unnamed rival. That’s why Lightning Guy blows the roof off the place and kills the madam when he takes Miao Yin, instead of just having her delivered to Lo Pan’s front door.
Word gets out that the Jade Dragon has a green eyed Chinese girl, and reaches Lo Pan. He orders the raid on the brothel, and sends the three storms to teach the Lords a lesson about who they work for. Jack manages to walk into the middle of both of these.
I’m pretty sure that was all the effect of the magic potion Egg gave them right before the big fight. That’s what gave Wang the ability to do all those impossible wuxia leaps when he was fighting the Storm.
A yaoguai maybe?
Nah, the BTiLC world just has demons and monsters in it.
One of the charms of the movie is that it’s basically about an American who stumbles into the last act of an epic story, and assumes that he’s the star of the whole thing. There may be something profound about American-Chinese relations in that.
Anyway, Lo Pan and Egg Shen clearly have a history, and I suspect this movie isn’t the first time Egg Shen has interfered in Lo Pan’s schemes. How long back that enmity extends is open to question. It certainly would not be out of place in this movie for Egg to be a few centuries old himself, or he could be just as old as he appears, and has only been fighting Lo Pan for the last few decades. Maybe he learned about Lo Pan from his master, who also spent his life opposing him, and who learned about him from his master, and so on.
Information about Egg Shen? Recreational torture? Snacks?
Maybe he just doesn’t like her all that much.
I’m glad they didn’t make a direct sequel, either, but as it happens, I caught a great movie on Netflix the other night that could very well take place in the same universe. It’s a Korean action comedy called Woochi. Kung fu wizards fighting monsters on the streets of modern Seoul. I enjoyed the heck out of it.
