This is the first ever review I've written in my life so please bear with me.
The translation was a little wonky especially regarding Chinese idioms and slang words which is understandable but overall, the translation was good and I appreciate the translator for taking time out of their busy life to give us this QT novel.
Regarding the novel, there are in total four arcs. The first arc was my favourite arc as there were more emotions placed into the arc. The arc gave us an insight into the process of how Ruan MingChi fell in love with JiHao and his reaction towards his own feelings. It felt a little unreal as they got together and spent the rest of their lives together due to the seemingly uncaring attitude JiHao had towards their relationship. It was like he was only just going with the flow and even at the end of the arc, it wasn't sure whether he truly liked/loved Ruan MingChi or not.
The second arc was my least favourite arc as it was quite bland and boring due to the fact that the MCs were so OP that no challenges could get in their way. Any obstacles that tried to get in their way would only be easily broken through by them. The only thing that kept me going through this arc was the MCs' relationship. But that only led to disappointment when as soon as the MCs got together, there was a whole ass time skip towards the end of their lives in the world and we barely get to eat any fluff from them in the arc.
And then the third arc. I cried a lot in this arc. Like a lot. Like snot and everything. This arc was just full of tragedy (in Ruan MingChi POV) and I read a lot of the comments saying about how this resembled killing stalking except with a happy ending. Anyway, I'm not going to comment much about this arc except that you'll cry, at least like a tear or two.
The fourth arc I have nothing much to say about except that all the confusion that was still left after reading to that point will be cleared up after this.
Spoiler
So I'll go into detail more here about what I've read.
As have been said by another reviewer, the first arc is a swimming competition world, the second arc is an entertainment world, the third arc is a master and servant world and the fourth world is a cultivation world (s).
In the first world, JiHao is Ruan MingChi's senior and they are both in the same swimming team. JiHao transmigrated into the body when the original was in the midst of bullying Ruan MingChi due to his (OG) jealousy towards Ruan Mingchi for always being praised by the coach for being good at swimming. In the first few chapters, you'll be confused by the sudden strange information given to you by the author, but that's fine as I'm here to enlighten you as to what was going on.
So, essentially, JiHao was a researcher in his first life and he transmigrated into a book, becoming the Heavenly Demon in the book. He was destined to fight with the protagonist of the book's master, Ruan MingChi, and kill the master which would result in him dying by the protagonist's hand after. He accidentally wounded Ruan MingChi severely after first transmigrating into the story and because he didn't want to die, he planned to go into Ruan MingChi's sea of consciousness to mend the qin spirit (the qin is the spiritual weapon of Ruan MingChi) which will in turn help save Ruan MingChi's soul. It was mainly self-defence that JiHao fought back as when he first transmigrated into the novel, he was already fighting with Ruan MingChi and he (RMC) had the intention to kill.
Now, here comes the truly confusing part as I have also not yet figured this part out. How was the qin spirit related to Ruan MingChi's soul? And why was fixing one saving the other? From what I had gathered so far, I think that it is because Ruan MingChi and the qin spirit sort of fused together. So, Ruan MingChi is the qin spirit and the qin spirit is Ruan MingChi but even though I'm confident with this answer, I'm still not sure whether this answer was the correct one as the author can be really confusing sometimes.
So, in order to fix the qin spirit, JiHao has to enter Ruan MingChi's sea of consciousness and into the illusionary worlds there and fix the worlds. He had to fix 6 worlds in total and he had already failed two by the time he entered the world for the first arc. I won't write about how the worlds are fixed as you'll be able to find that out by reading the novel.
In the first arc, it was about establishing the MCs' relationship. In the second arc, it was about how JiHao chased Ruan MingChi. And in the third arc... moving on, at the end of the third arc towards the fourth arc, when JiHao chased the white beam of light fleeing from 'Ruan MingChi's' body, it was revealed that the white beam of light was, in fact, Ruan MingChi. So why were there two Ruan Mingchi now?
Ruan MingChi (the one being chased by JiHao) used a scroll/painting to trap JiHao in a world of his own making. He sealed the memories of JiHao so that he wouldn't be able to remember anything. But not only did he seal JiHao's memories, he also sealed his own's.
To clarify some doubts about why the JiHao and Ruan MingChi left in the third arc could still live on normally even after the 'souls' left the bodies, from what I could understand, JiHao left a little bit of his divine consciousness in the body so that it could continue to work normally even after he was gone and I can only assume that Ruan MingChi did the same thing either out of attachment or something that I don't know about.
Either way, I'm still upset about how rushed the ending of the arcs were (excluding the fourth arc). The relationships were rather fast-paced (not that I'm complaining) and I would've hoped to get more chapters about the MCs lovey-dovey times but alas I'm not the author and I'm just a reader. I hope that my explanations helped those who are still confused about the story. I'm not sure if I included all of the confusing parts but I'm sure that I've at least got the majority of it. Anyway, thank you for reading my long-winded review and happy reading!
