Help!

I’m looking for this manhua I read a while back. It’s fantasy and the MC goes into a book.
The MC is deaf, wears glasses and has black hair. He was giving criticism or something on this favorite book that released the last chapter (?) Or uploaded a new chapter. He falls asleep and wakes up in the book. He sees a cat with two tails(?) that guides him to ML. ML is a skeleton, straight up bones. MC has to kiss ML to wake him up, ML wakes up and just starts sucking the soul outta him to regain his body. MC passes out. The ML is like an over powered character, he can shape-shift and is like and elf, troll, wizard, demon and just a bunch of stuff mixed together it’s kind of weird. He turns into his human form at first then turns into a tiny elf or smnt then into a demon, he can’t really control it. I remember one big thing is when it starts raining acid and the MC carries ML to a cave and gets hurt really bad cuz he was covering ML from getting acid rained on him. I hope this is enough information that can stick out for someone to pin point what it’s called. Thank you!!!
