I would be interested to see how this story turns out. History is always written by the victors and who knows what is the real story behind dethroned Emperor Liu Shan. Is the narrator really 'altering' the course of history by acting in Liu Shan's place? Or are they simply getting a first hand account of what truly occurred behind closed doors of the Wei capital?
One suggestion I would make is to spend a little bit more time describing how the narrator feels about suddenly being thrust into the body of a past historical figure. The speed at which they found out who and what they were was pretty fast and I assumed a drastic event like this would of taken a little bit more time to figure out.
I would also suggest taking a little bit of time to introduce new characters properly. I had to re-read a passage a couple of times because a character was suddenly relevant and I thought I missed something.
Keep up the good work! I look forward to seeing the finished twine.
