Some points didn't match up.
There was no way the original Feng Ao Kuai would want to sacrifice his life in order to trade with the original Nan Hua. Feng Ao Kuai was an ambitious person and also someone who had high dreams.
When Nan Hua talked to him, she had long noticed that Feng Ao Kuai was someone who wanted to reach the peak in his own way. His ambition and dream was not small. It was not something that could be easily traded with the life of another person.
The current Feng Ao Kuai indeed would not hesitate to sacrifice his life if it meant that he could save Nan Hua.
Not that Nan Hua would allow him.
But if the original Feng Ao Kuai dared to sacrifice that much for the sake of the original Nan Hua, it could only mean one thing. Even in the original story, the original Nan Hua had somehow made the original Feng Au Kuai followed her and become her right hand.
Was the original Nan Hua merely a cold and unloved daughter of Nan Family?
