[V4] Writing style in the first two volumes

It's just me or you also find that the writing style in the first two volumes was a little confusing and hard to digest, I felt like the author used some rhetorical, mysteries , complex and suspense sentences (or something like that, I can't really express it in proper way) that confused me to know what happened exactly

For ex: " It was a math equation, but klein doesn't have enough factors to calculate it"

(The sentences not from the first two volumes, but i think u know what I mean)
