Story of The Ancient Demon King! Chapter 50 Discussion

This is extremely badly written or translated. There seems to be no feelings or build up in the climatic scenes whatsoever.

The author seemed to have taken inspiration from emminence in shadow but had failed miserably to account for what makes the shadow so good. The main character seems unwilling at best. He does no evil deed, yet calls himself demon king. He hides his identity for very little reason unlike shadow.

Change of POV come at the worst time. It feels like the author is trying to create misunderstanding inside the characters itself?

The author gives no reason why he knows such level fighting style and the background is also very unclear. Rest is history.
