How do you obfuscate lua scripts without the usage of loadstring? [closed]

I've searched a bit on this topic but no one seems to know. It is possible and I do have my hands on an obfuscator but I want to make my own.

^ this is a simple snippet of a 2000 line print execution. I do not want to learn how to make something this advanced but I do want to know how to do simple obfuscation.

There's a vermillion post of a simple obfucator script. I don't have the link and I don't know if it works but it used string.byte Protogen_Dev 268 — 5y

Yes, there is something called vm obsfucation I think. I'm pretty sure it works by creating a custom lua vm in lua and then running its own custom bytecode in its own interpreter. vm obsfucation is a good choice for hiding the logic of the code when reading unlike just changing variable names.
