My instinct says so. novel's most of is all about Susha's palace politics, some of Jinxiu's. And the last part…
The last battle maybe removed because in the drama the throne battle is in Susha not in Jinxiu as novel..Here is like if Suige's step-mother is empress then his father must be emperor..then Suige should be emperor in the last phase of the drama..but in novel new emperor was xia jingshi's brother and xia is the son of dead emperor.
