Shen Jibai, a graduate student in the Department of History (before time travel: Shen Yi), woke up from a dream and became a poor scholar who died of illness in the last years of Dayan.
It's nothing. The really scary thing is - he knows that this country will die in twelve years.
The Beidi cavalry, the fall of Yanmen, the emperor's escape, the change of ownership... Every date in the history books is engraved in his mind. He was supposed to be the only person in the world who knew the answer.
But he soon discovered that knowing the ending may not change the outcome.
He used his knowledge of physics to create the "Gewu Sword Technique", used his knowledge of chemistry to make gunpowder, and used historical predictions to avoid floods and prevent unjust cases. Everyone thought he was a genius from heaven, but only he knew that he was just copying an answer sheet that had already been written.
But when he actually stood on the top of Yanmen Pass, history suddenly stopped listening to him.
The person he saved was supposed to die; the female general Jiang Xuetang he fell in love with was supposed to die in battle; the king of Jing'an he trusted, Xie Chang'an, finally drew his sword against him. And his brother Zhao Wuxie blocked the knife for him. Before he died, he only said: "What you owe me, you will pay it back in your next life."
A deeper secret then emerged - Beidi State Master Yan Beigui also came from "outside"; and his master Liu Sanbian drunkenly told him: "Twenty years ago, I also came from 'outside'."
He was never the first. So will he not be the last one?
Being a stranger in a foreign land. But strangers can also become homecomings.
