First this novel sets up a vibrant world like nothing I've seen before even in something like BTTH they just stuck with their are a few continents the end. But this novel has many worlds as well as the heavens represented by the 9 mountains an lakes.
Then their are the powers and legacies that the MC gets you fell like the journey is and adventure to find the one ring but wuxia style. With him following in the Demon Sealer legacy.
Third the MC's perfection and strength progression is not fast and not slow but measured. I felt I was chasing perfection with him.
Then the characters weird crazy and unique some want to help the universe others are just trying to gain more power.
Last but not least the writing is amazing always showing the coolest and most dramatic story-line in the most fantastical way.
First while I love how fast the character gains strength and becomes powerful. It leave behind a problem FORGETFULNESS at one point the character gets at legacy from some Blood Mask guy. He get a pet the blood colored Mastiff cool right. But after he leaves the world he is on and goes to his dads clan it is never mentioned again. Just like the wooden sword title get this Immortal slaughtering swords he uses them to make a time a treasure but never uses them after he live for the Immortal realm. This happens with a lot of stuff that was supposed to be useful later on when he becomes more powerful but gets discarded when he guess what BECOMES MORE POWERFUL.
The next thing is only a problem for about 100-150 chapters. RUNNING AWAY. After his first sect that he was forced to join is basically destroyed it is known that he might have something important on him so what happens. He runs then hes caught so he kills some people. Then he runs then he kills some people then he runs. Then he insults some people then he runs. This happened so much that I nearly gave up on this novel.
The last part I took issue with is more my opinion and not fact. And get ready cause its a super spoiler:
The ending has all his family dead all his friends dead all his clan and sect members dead but him and his girl alive. The nine mountains and rivers dead he is all powerful and could make it all come back but he just leaves.
Question what was it all for if not to protect everyone what was all that power worth if you are just going off somewhere to get more power. I think they truly f**ked up the ending. NOT like Desolate Era he had a chance to get even more powerful but instead destroyed it because he felt it was a threat to his and his families peace.
It was very annoying because his Clan and family had just become very powerful he had kill all the traitors and got revenge but the writer had to go one too far and give him another thing to fight a curse.
In my opinion it should have ended with him murdering all the traitors and killing all the 9 heavens that betrayed the nine mountains and lakes. As well as the invaders from outside the universe.
While this is definitely a harem novel but it goes about it in a fairly realistic way. How you might ask? Well the MC loves this girl and she is the main reason he reincarnated and the main reason he died in the first place. So when he meets her when he reincarnates he of course wants to make her love him like he loved her all those years. And because she also secretly loved him too he succeeds easily in capturing her heart. However because she loves him so much and wants him to be happy no matter what she allows him to bring in other women as long as she is the first and most senior wife. This gives it a good flavor like he is not betraying his love and give very good comedy when hes chasing girls but get his first wife that he loves mad at him.
Then their is his knowledge and powers (that he gets after having s*x for the first time). The way he uses his past knowledge is really cool. Add on super powers and it becomes bad ass.
First and for most one thing stuck out big time during about I think chapter 150. Its when he gets a car. Now he is discussing about getting a car and mentions that before he reincarnated he use to race cars so HE KNOWS HOW TO DRIVE. So whats the first thing he does when he gets in his car and pulls out of the drive way? HE GETS IN AN ACCIDENT. So I say okay just one could have been the other d*ckheads fault but no in the course of one month he get into THREE accidents. Are you f**king kidding me.
Next the other big annoying thing is the villains are really stupid not that I care I don't even need villains in a novel but I hate repetition unless you can make it interesting. This is how it goes.
A guy wants to get with one of the harem members. NO you don't. And they get into a fight oh and he gets beat. But OH NO he has a strong family background. BOOM they get beat too. Don't worry girl ill keep you safe. OH no another arrogant guy wants you POW hes down. (Girl swoons) THE END. Like that repeated over and over all that's different is that the peoples background get bigger and bigger.
