Yang Wan's crossing and her vindication of Deng Ying in the 21st century are like a Mobius ring. You can't tell who met who first.
First of all, apart from the modern ending, Yang Wan's first question was "Does he have someone he likes?" As a historical researcher, she should ask about Deng Ying in the imperial court, not about love. At the end, Yang Wan asked Deng Ying again, "Are you Deng Ying?" In this sentence, I guess she has a memory of the Ming Dynasty. Because for her, she already knows that the person in front of her is Deng Ying. What is the significance of asking again? Is to confirm whether he has a memory, whether it is Deng Ying of the Ming Dynasty.
So, we can understand that Yang Wan and Deng Ying, who spent decades together in the Ming Dynasty, came to modern times after their death.
When Yi Lang ascended the throne, in order to warn the eunuchs of the dynasty, he asked those who recorded the history of Ming Dynasty to record that Deng Ying was punished in the year of the year, so it is not so important whether he was punished in the year of the year. Because he survived.
Therefore, we can understand that the history that Yang Wan saw in the first chapter-Deng Ying was killed in the year is false. It may be that Deng Ying was not killed in the year. No matter how many times he repeated it, he was saved by Wan Wan.
