I dropped this at chapter 106, I honestly couldn't read anymore.The story is interesting but nothing over the top, I found it a bit boring with no great scenes, the English in the first few chapters is atrocious but then the author starts using some kind of Shakespeare AI that is way over the top, like he's looking at a flower and the description is something like "the orange color was brighter than the sun, it's brilliance captivating everyone who appened to gaze upon it" like bro it's just a flower. Others have pointed this out but he doesn't have the personality nor the intelligence to take over the underworld in 3 years like it's stated. Also the author loves making the mc break through a rank during a time skip and not telling you, so you never know how strong he really is until the end of the battle. Overall it's pretty bad but it's readable, for me it's just too boring
