Help needed with il2cpp game

[SiamangTunggal]

currently this game seem like protected. but somehow i manage to extract global-metadata.dat from base.apk in /data/app/ then dump the libil2cpp.so. from dump.cs i found the offset for gold and jewel but somehow i can not edit . i try the script class and field offset finder v4 script but to no avail nothing is work for these two . i try using go-to in Xa region , then used offset calculator for GetGold , edit the value in Dword . nothing happen. do i need to edit in Arm code to make it happen ? somehow before this it used to be working but i forgot how i did . it was several years ago

here.  ise this script.  entwr the method offset for public double GetGold() {}  and enter how much gold you want and select double.  you might have to spend/earn to see change (if this is even the correct hack)
