Later generations will say that Qin Shihuang Yingzheng spent his whole life seeking immortality, which is absurd and nonsense. As everyone knows, immortality is real.
I am the auspicious beast Chenghuang. It is described in the Classic of Mountains and Seas that "the country of the white people is in the north of the dragon and fish, with white bodies and hair. There is Chenghuang, which looks like a fox with horns on its back. The lifespan of Chenghuang is two thousand years."
"I will clean up the world, unify the world, and become the master of the world."
"These thousands of miles of rivers and mountains belong to me; all the people in this world belong to me; the auspiciousness among the things in the place that day - Cheng Huang, naturally it should be mine!"
(Two male protagonists + strong confrontation + historical consistency + no female protagonist)
