The Ymir part was way too quick, should have been more spread out in past chapters and should be given more time, which it undoubtedly will, but this is otherwise good. That is, as long as that little brat gets squashed. Conversely, it's kind of lazy to blame an ancient king and have plot armor of immediate spin regrowth, again, through the power of talking, which is kind of annoying.
As for the people acting like this is 1000IQ and godly planning, you've clearly never taken an English class or creative writing of any kind. It's executed well, but the first rule to writing fiction is knowing the beginning and the ending of a story. Doing this, the "amazing foreshadowing" shouldn't be so amazing, it should be box standard.
It's hilarious how bipolar the comments on this series are as of late, one minute absolutely trashing it, then praising it as god writing.
On an unrelated note, what is the centipede ass looking spine. On another unrelated note, RIP to all the missing chapters.
