Damage adaption to Entity's and Environment

I am trying to make an addon to my custom origin that would allow me to adapt to different damages in Minecraft. For entity's after 10 kills of that specific entity and for environment after taking damage for the first time I adapt after 60sec or 1200 ticks. But I cant get the environment part to work and even the entity part has some flaws.

Here is the code: https://pastebin.com/M65FmeBT
since I cant really put screenshots of it since there is so many

Thanks for any help that I can get.
