Review Detail of Nullabutton in I reincarnated as an Immortal caterpillar?

Oh, no! Only 41 days left! "Immortal Caterpillar" is such an eye-catching combination of words, I couldn't help but click :) I like the idea of extendable life-span, but have yet to see how it's done so am looking forward to future chapters (or maybe I've missed the part?). But really, you write rich sentences. So it is a bit of a downer when you just slap an imaginary screenshot of the status and their numbers instead of writing them out in full. BTW, took me a while to realize -X- is used as a line breaker.
