Sounds about right for a fight in chapter 600+, the MC has so much bs they can pull out of their ass that the reader probably forgotten 90% of the shit they bring up.
A fast food theme cultivation novel sounds really interesting.
Cultivation is where all the enemies that can kill you with their farts are busy for 1000 chapters. Where you take a weird pill and the proceed to sit on your ass for an extended period of time to level up from level 3 ching chong to level 2 ping pong.
Afterwards you will proceed to court...
