Read to chapter 112. I came to it hoping for a slightly worse legendary mechanic. I felt disappointed. The writing is good, no errors or anything, and I think the story has some interesting things to it, but I can't stand the MC. In particular, his indecisiveness on hiding or showing his power. It also feels like the MC is wasting a lot of his time and throwing away his advantage. He also doesn't seem to use his knowledge from his previous life a lot.
