Review Detail of tyr12345 in Otherworldly Devilish King

The story is ok. The plot isnt completly thought through. For example the mc encountered thugs two times in one day. The first time the mc seems to easily take care of them without bloodshed. The second time he had to draw a sword and kind of bluff to get them to go away. Then he has discovered a palace with a libary, where he could probably get enough information to become way stronger, than he already is, but he doesnt do that. Why? The author makes the mc do illogical things to force his plot and hold his power level back in order to make future fights hard for the mc.
