The uninvited guest

Author, elena (mc wife ) should have senced his soul , as you said that their soul us connected, we should expect that he got taken after he achieved his goal in lower realm or they should send noir (death guard or mc future wife ) to keep him safe in case of danger etc. what I want to say is most logical decision is he return to clan in very short period time unless there is going to be war as to protect him, keeping him hidden in the lower realm or safe zone in the immortal realm where no one know his alive etc . Finnaly, personally I would have liked that he will return within 50 chapters. or is going Typical and most annoying is climb the realm one by one (which is waste of time and repeated scenes). Still for those read this , didn't read  the novel i would recommend you to read it, it's awesome  plus thank you  Author for reading this .

Puny little urban novel cliches, nationalism, and academy / school arc......... DROOOOOOOOOOOOOOOOOOOOOOOOOOOOOPPPPPPPPPPPPPPPPPPPEEEEEEEEEEEEEEEEEEEEDDDDDDDD!!!!!!!!!!!

Now we wait                                                                                                                                                                                    

The MC has as much personality as stale bread. The typical filial shtick with the annoying mentality of 'returning a droplet of kindness with a waterfall'. This MC has no individuality, nothing to distinguish him from the 100,000 other MCs with the exact same personality. If that wasn't enough the translation quality is terrible. The quality noticeably drops every 5 chapters. For instance, some words are directly translated into English without considering the context. This is why this novel calls cultivators as 'fairies'. Obviously rushed!Honestly, I have no clue how this rubbish was picked. The story is awful, character design is bland, and the translation quality is reminiscent of machine translation.

It's so addicting huehuehuehuheuhuehuehueheueheuehuehrurhrurhrurhrhrurhrrA .MUUUUUUUUUUUUUUUNNNNNNNNNYYYYYYYAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!!!!!!

Dont even bother reading this its so boring it would be a smarter decision to just watch 5minutecrafts in youtube its not as braindead as this novel ...AND WHY WOULD SOMEONE NAME IT THE DEMON KING SYSTEM like it gives me braindamage the more i read this

I absolutely loved this. it added such a nice aspect to the usual slice of life. i was very invested in the story and managed to finish im a day. overall 10/10

a bit spoilerAhem! Ahem! as I continue to read this I consider myself stopping it as I really hate how he take Selena with him, but as I read more chapters and also think about klautz pov, I started to enjoy this more than I can think, like why hate a woman if you know that she will not betray you while also do willingly what you command to her.I hate the part where Verona interfere when klautz was fighting with Eli, but thinking about it, it was really necessary to do that part as we need it to do some character development as it was boring if she suddenly became survibedient to him. so for that part you really great author.For the lemon part, you also do great at that author that I begun to think if it was based on experience GHAHHAHA but if my hunch is true can you kindly teach me sensei! There was some typo but it was so little that you will not care about it. I also like how thick skinned our mc when they were in that secret room where they first met Verona on the bonus stage. where he do the deed with Selena even she was at that room GAHHAHHA it really turn me on GHAHAHHA and from that part I know that something within Verona will be going to awaken GHAHAHHAH I'm still at the 80s chapters and it was already awesome so I expect that it was more going to get interesting when I caught up
