not sure if I can ask about sound files here, but this is from Eternal City.

First, I use FSB Extracter to extract sounds from res/sound



But I cannot play it and not sure why...

The game is program. We can analyize binary to find how it read epkx file.
I will try this way when not busy.

This would make more sense. Of course the encryption can be found and I don't think it will be really hard but I basically have no interest for this game. That is why I didn't bother.

Still it might help with other Netease games so give it a shot

I don't have the latest files. Maybe they encrypted the archives now.

you can open the raw data in PVRTextool and test various formats.

edit
now i see this byte pattern in the encrypted headers and it is looking like xor based on the results
