Super Mecha Champions: .npk unpack

[Vlalchinanya]

Hi, I would like to receive models from the Super Mecha Champions game developed by Netease. I tried using the nxpk.bms script available on the forum, but it didn't work. Is it possible to write a script that will work for the archives of this game? Thanks in advance
I attach an archive with a .npk file to this topic

The file index table is encrypted, so nxpk.bms does not work
This is as bad as EXPK
