How different would the manga be from the history by the end.

So what made me ask this question was shin's character. In the history ri shin is very mediocre and uncharismatic and down right not worth mentioning not only that but he was held responsible for the biggest set back for qin dynasty in the records it's always the wang family that's in the spotlight. Li xin is always depicted as a bad general that caused the biggest upset. Not only that unlike the show li xin was a member of noble family related to li mu not to mention the manga version is down right legendary level of general considering his track record.

So basically from the start ri shin was nothing like li xin. But still he was chosen as the protagonist and since he was chosen as the protagonist and Hara from the beginning made very drastic changes it's not only li xin but it's also the emperor qi shi Huang who was considered a cruel tyrant is portrayed as a benevolent king. And then there houken who in reality was a old man. But he's portrayed as a god of war.

All these drastic changes in the characters and I didn't mention but overall history of conquering the other nations were done by Hara which begs the question how different will the story become compared to real history by the end.
