The Doomsday Modifier

I think the development prospects of this book are okay, but does it lack a little bit of interest (personal opinion)? In fact, some jokes can be added appropriately? Or is it an emotional line? Small goals and the like, overall the book is okay, I hope the author will continue to work hard [note]

Give you 5 stars,

There is no tailless jump and I can't understand it at all.
