Minecraft TAS - How did we get here?

This is Tool Assisted Speedrun, meaning that i used slowdown, savestates and rng manipulation in order to get as close to perfect time. Don't take it as a real run.

Seed: 1042987425385626
Version: 1.16.1
Hours of work: 40+
Savestates: 81
Disclaimer!
This run is actually impossible to be recreated in vanilla minecraft. This is because there is a glitch that makes your effects not save when you teleport from end to overworld. Since i realized it when i was done with almost whole run, it's supposed to be glitchless run and strategies from this run can be used by other people, i made it so the glitch doesnt appear here, but keep in mind it exists!
Enchantments glinde and advancement announcments looks weird, this is because they are not affected by tickrate changer, and after speeding up the video they are faster then they should be.
