I Can Rewind Time and Survive

The setting is okay, and the writing is online, but the plot is a little bit toxic in many places, and the rewind setting is obviously very enjoyable, but after reading most of the part, I didn't write out the exciting points, or it was brain-burning instead of refreshing. The protagonist gave me the feeling that he has become bolder but his brain has not grown, and there are always some confusing operations. Finally, since the magnetic field theory and button props have appeared, why are there no shields and the like? I see that in some plots later, other forces or areas have instruments that disrupt the magnetic field and cause semi-spirits to be unable to use their abilities. And since weirdos can be killed by combat power? Why is it called weird? Isn't it better to just call it a ghost? Of course, this book can still be read. Many details are indeed a bit scary, but it doesn't read like an online novel, but like a collection of short stories.
