It is a unity game whose chinese name is "梦幻新诛仙".https://mhxzx.wanmei.com/
However, it can't be loaded with Asset Studio. Please help me with it.

Well I looked into the .obb file to the game and found that you cant open it.

I opened it up in hex to find the data looks compressed or encrypted somehow.

Thank you ! As you can see, the game hasn't been realeased. The *.ab file is from beta version of the game. So I am not clear about the *.obb file, since I didn't find it in the APK file.
