Review Detail of Zikiziki in Chaos' Heir

I really enjoyed this story originally and it had good run for hundreds of chapters. But at some point the story comes to massive halt, we get 1 chapter of progression and 9 chapters of MC romance with new random girl. What's worse MC isn't a casanova that gets the girls because he wants to but simply typical loser that pretends to be faitful but immediately goes for random new chick as long as he spends more than 3 chapters with her. So yea, all that great world setting and power system and story set ups that we see early in the series are ruined whenever author gets horny and instead of keeping it to himself, he puts it into the novel.
