How to make a Full lua executor

So i seen way too many "Level 7" exploits out there and i was wondering how do the people who made them make it execute the Lua commands inside the game files.

Now searching this on Google or Youtube is useless because everyone is using the wearedevs API from which you can't learn anything.

So the real way to find out is to come to this forum and ask.

Also a lot of people sell these programs/exploits for over 20$. (Synapse(20$), ProtoSmasher(30$), Veil(40$), QTX(50$), Intriga(45$
))

In short:
