You were abducted by the system to ancient times. When the system said that you came to the time when Qin Shihuang, the first emperor of the ages, Ying Zheng, had just ascended the throne.
You found Ying Zheng excitedly, rushed to Ying Zheng's feet, hugged his thigh and cried.
Ying Zheng didn't blame you and was very kind to you.
In the following days, he adopted all your suggestions and implemented all your strategies.
You improved the dynasty step by step by relying on the knowledge you learned in modern times. When Ying Zheng got old, he did not seek immortality or Buddhism, but you began to look for opportunities for him to live forever.
All the ministers in the DPRK and China are trying to impeach you, but Ying Zheng remains unmoved.
Finally one day you were curious about why the one emperor in history trusted you so much and asked this question.
He answered: You are not the first descendant to come to me, but you are the one who has been with me the longest. The first appeared when I was young and died under a stick to feed me. The second appeared when I was young and died at the hands of assassins to protect me. The third, fourth, fifth... I don't know why you come to me one after another, but I know that you are all here for me.
At that moment you felt relieved, so what if there is no elixir of life, the ancestors are the ancestors
"Your Majesty! I know the global map, and I am willing to unify the world with Your Majesty!"
