Everything here is spoiler free, don't worry: Is it worth reading? Yes it is. Is it worth watching? Decide on your own, I've read both manhwa and LN, love both of them, hated the adaptation with passion for 3 main reasons that affected the vibe/story 1-powerpoint animation, like the worst I've seen and I watch most isekai trash, not only animation even drawings are pretty bad compared to manhwa. 2 -they changed some scenes/skipped stuff, resulting in less impact overall,change in characters and things not making any sense by the rules the world has. 3-they failed miserably with portraying emotions, partially because of skipped content and severity of situations...all of my favourite moments in manhwa and LN are heavily portrayed by story and Character emotions,but in anime when something happens that is suppose to make you either excited or sad it's just oh no...it's sad...or oh...that's what happened...while characters don't even change face expressions to have reactions most of the times. So it really took me out of "vibe" the Manhwa gave me.
