As someone who has took decided to look a bit further and machined translated all the to the most recent chapter 250 This is one of those true gems and it is one of the better 'reincarnation' story more well balanced in its pacing and approach. It is a curious blend of actual history and Xuanhuan, this gives the reader an insight into the culture of the Chinese of the time, it is evident that the author is a history buff given the time period and the political intrigues affecting china in that time and its subsequent downfall. This chronicles our MC's attempt to stem that flow, albeit with mixed results.
The characters are not too overpowered, barring the occasional MC's plot armour as we know if the MC dies the story is over; It is however tastefully done and the author has done good job in representing both sides of any argument from the standpoint of protagonist and antagonist (s)
If you're looking for something that is different from the usual trope of reincarnation where it's just a power grab and power up where the ending is fast approaching this may not be for you.
If you' re looking for something decently paced, immersive in his world building and political intrigue, grounded in some basis of fact, characters who are not cardboard cut outs and do contribute to the story then this is something that may pique your interest.
P.S. Concerning the MC's logic, this is all explained in the upcoming chapters with him not being able to give anything away which hearkens back to what I said about formulating an opinion and a review on minimal information. Which is understandable giving the small sample size no offence to the previous reviewer
