Is it really chapter 5 the continuation of chapter 3?

Turns out, chapter 4 is missing and the old bald man in chapter 3 is now a good looking dude in chapter 5

Update: Is the author high or something? Wtf is this plot (╯°Д °)╯╧╧

update: I swear the art is sooo good, but man, the pacing, plot and panneling of fight is just not giving it good
