Open the 64-bit CheatEngine, and start after binding to the current game process:
1. Choose to search Array of byte
2. Remove the tick in front of Writable
3. Select the HEX in front of the search box, and then paste the code given by the boss
80xxxxxxxxxxxx74xxb8xxxxxxxxxx80xxxxxxxxxxxx74xxb8xxxxxxxxxx80xxxxxxxxxxxxb8
After clicking search, a unique address will pop up
4. After double-clicking this address, it will be added to the list below
5. You will see the full picture of the string of codes. After double-clicking on it, copy the entire string of codes with spaces that pops up into a blank text. Clear all the spaces by replacing the spaces, and then copy them out
Then use Winhex to open the execution file itself and click on the telescope icon with the word HEX to paste the entire string of codes that you have just cleared the spaces in the text. Once you search, you will find it. You are not assured whether the only thing you can do is to press F3 again.
Then look at the line of code located and change EE 02 to 16 06
Operate the other two lines of code given by the boss according to the above steps
b8xxxxxxxxebxx80xxxxxxxxxxxx74xxb8xxxxxxxxebxx80xxxxxxxxxxxxb8xxxxxxxx0f45
74xxB8xxxxxxxxEBxx80xxxxxxxxxxxx74xxB8xxxxxxxxEBxx80xxxxxxxxxxxxB8xxxxxxxxB9xxxxxxxx0F45xx
Save the current executable file you modified in WinHEX, and be careful to exit the game program you are running
You have completely unlocked the 1558 level upper limit for your executable file
