Turn out, it's pretty easy ?
The game uses little tricky value protection technique, it use 8 bytes split to 2 part of 4 bytes to encrypt value.
For example:
If you have less or equal to 4 digits number crystal let's say 123 then the game encrypts it to 0x00333231 0x73000000
If you have more than 4 digits let's say 123456 then the game encrypts it to 0x36353433 0x73003231 (I guess its limit is 8 digits? Yes, you can overwrite the 0x73 to achieve 8 digits number)
P/s: 0x mean hex number NOT dec so when you search or edit value remember to add h
