3.7. It's better than 3 stars, but not quite up to the four star level.
I had a bit of a hard time getting into the novel, but I'm glad that I stuck to it. On NU it's genre is Xianxia, but tbh it's very different from most other Xianxia novels - it feels a lot more like a historical novel. Clans, family, imperial politics - and the romance and past of the two main characters of course. The summary is not wrong but somehow it made me expect something very different.
The novel starts out shortly after Lin Xin's rebirth. In his past life LX was a trusted subordinate of the emperor and made a lot of enemies, though as the narration quickly tells us, he already had enemies that he was gunning for before that. Now he is back in his childhood "home" under the "care" of his paternal family. He hopes to get away from them soon and find his master, though he is puzzled by some of the changes that seem to have occurred already even though he hasn't done anything.
To the reader one of the changes becomes quite clear: LX is not the only one who has been reborn, but Shen Lou, a famous and much celebrated young man, and the heir to one of the most powerful families in the empire has as well. In their past life the lives of LX and SL had entangled, and they clearly had feelings for each other, though circumstances lead to some misunderstandings and missed chances between them. SL is back as well, and there are two things he is focusing on: finding and protecting the young LX (which includes preventing him from killing his master) and protecting the country from the barbarian invasion that lead to thousands of death beforehand.
Due to some of the changes that had occurred since their rebirths, SL and LX meet a lot earlier and SL takes LX with him and away from his family. At this point neither of them know that the other one has been reborn as well which leads to some humorous situations. Eventually, LX ends up with his master again and it becomes obvious that what SL and LX knew in their past lives was always only a fraction of what was going on, but what they knew and assumed made a lot of sense in the context of the story.
Though misunderstandings and misconceptions played a big role in the story, I was pleasantly surprised by how well done it was. The misunderstandings while sometimes obvious to the reader were not annoying and dragged out and it wasn't just our main characters who suffered from them. I also though that the revelations from the past life and some of the new ones in this life tied together really well. LX though he knew who his enemies were, but he was wrong and that means some of his actions were wrong as well - he is not just a righteous hero, and that made him a lot more likable.
I also enjoyed the relationship between the two main characters. Despite loving each other (and eventually realizing that they were both reborn.. one quicker than the other), they still have a life. Sure, they would like to attach themselves to the other's side all the time, but that's not just how life works sometimes, and I thought it was great that they actually had to separate sometimes.
The side characters were lovable and actually appeared more than once. There was actually a surprisingly large cast of characters who appeared multiple times and had relevant roles, such as the master, senior brother or even the sons of LX's enemy from his past life.
The extras were nothing special, though they were more relevant than more fluff. In fact that dealt with some relevant issues from the main story and showed was happens to the main leads and some of the people around them.
With all that said, why did I not even give four stars? It's partly the writing and partly the translation. The first is really annoying when it comes to its flashbacks and sometimes you have no idea if it is a flashback or not. And the other one... well. It's not bad, its just awkward. For the most part it is understandable. There are some he/she switches in the later chapters, though I don't think the translation I read is MTL. The biggest downside was probably the titles and the courtesy names and how inconsistent they were - especially when it comes to LX. Honestly, even by the end I have no idea what his courtesy name is, there are four options. The titles are a bit more... complex? Like, leaving aside that they are only sometimes translated, it's clear that a bit more though should have gone into which translation of the titles should be used. For example. Crown Prince just does not mean the same when used to refer to a Duke's heir as opposed to the emperor's- In Chinese the difference is clear, in English it's not and it would have been a lot better to just.. call it the duke's heir. It's the difference between a good translation and a functional one. And five+ crown princes just isn't a great look.
Should you read it despite those flaws? Yes, it has a reasonable plot and interesting characters. Also, there was a reason for the rebirth! Always a plus in my eyes. Don't be fooled by the comparatively small number of chapters, they are longer than you would expect.
