The issues with the plot occur basically from chapter one, where you are given the basic premise (rebirth, talk with the previous soul, pick up some regrets that the previous owner left the world with, etc, all in the first chapter), but you don't get a tremendous amount of backstory to it. While backstory being limited makes it quicker to the action, you kinda need to address the timeframe that the MC was originally from. For the longest time it was hard to tell if it was modern time to the past, or if it was similar time frames but different places.
The story gets no more solidified later. There will be characters picked at random that survive to be heard from at a future time, whereas others will come and go basically on a whim. Having not read the novel prior to picking up the first 200 or so chapters of the manhua, i don't know if it's simply a bad job of taking the original concept and moving it to the new format, or if the author simply didn't really plan out the storyline before devoting their time pushing through the content. It's not that i think it's worthwhile to spend a lot of time on the backstory or personalities of other characters in the story, but the storyline is basically dropped onto the reader, then the character is added to the MC's pose, and then you don't really get much more detail other than the 20-25 panel original story to understand that character, so when they disappear sometimes you just don't care and other times you are wondering what that character was about and what the heck happened to them. So when arcs of content happen, i guess i just wish we had more details about the supporting cast that is involved with each arc, and then occasional involvement thereafter, rather than just writing more plot advancement characters in to keep the story going and then disposing of them.
I've read about 20-25 of these types of stories, and this was simply mid pack for me. I've read far worse, but also far better.
