I came up with this method myself. I wrote an example prgram and tried to hack, but haven't found anything effective.
The method is simple though.

Here is how it works:
For every health value between 1 to 100 there is a code for it.
For example 50 means 1, 67 means 2, 23 means 3, the code is random generated,
just make sure health number is one-to-one correspond to the code.
The health number never stored in memory,
each time the health changes it is decoded, calculated and encoded at the same time.

So it is hard for me to find the address, and even I find out it is hard to alter the health number too.
I will post the source code of the example program and the compiled exe file.
The example program has 2 number, one is protected health number, the other is unprotected mana number, which you can try first.

The example program download link and the source code is in the attachment.

t4.exe
CRC: FF37E5F8
size: 69838 bytes

If you have any idea or find out how to hack please post. Thaaanks:>

changed/unchanged till found and then just freeze it. for health it's not necessary to know what the value means.

also, the decoded value is stored in a register between the execution of dc[d] and the encoding in ec[xxxx]
