"If you were asked to spend all your lifespan in exchange for traveling to the Qin Dynasty for three months, would you be willing?"
"There is a group of people... Who are willing to trade their entire lives to come to my side for three months."
"They said that they came from a world thousands of years in the future. Their homeland was destroyed and occupied by aliens. I need to rewrite history to change everything."
The first person who came to me across a thousand years was a doctor. He came to my bed to extend my life.
"Your Majesty, please... Make sure that civilization can continue!"
The second one is an agricultural student. She is only sixteen years old, but has a will comparable to that of a god. She will pass on what she has learned throughout her life.
"Teacher, did you see it? The student did it, and the student is worthy of your cultivation!"
The third person is a history professor who spreads civilization to China and allows everyone to become a dragon.
The fourth, the fifth... The... The nineteenth?
A total of nineteen people, they carry the will of 1.4 Billion people, just for the Qin Dynasty to change its face and prosper!

Future generations, just watch, I will lead the Qin cavalry to conquer a huge territory!
This time, I will protect you!
