Traveling Through History: Saving Hu Hai at the Beginning? ?

A mobile phone from my parents took me back to the Qin Dynasty, and the first task I was given was to kill Fusu. My name is Lin Xun, a modern person who is extremely ordinary. Until I unlocked that old phone and saw a photo of my parents in ancient costumes. The moment my fingertips touched, I traveled through time. The history here is going off track: Fusu is still alive, benevolent government is rising, and the people support it. And all this beauty is the result of a time traveler. A cold command came from my mobile phone: [Correction of history, death and sustenance. I became the closest alchemist around him and his most trusted betrayer. History does not allow for assumptions, warmth is poison. ——The hope in their eyes must be extinguished by me myself. "I'm not here to save anyone, I'm here to let history... Return to the blood-stained path it deserves." (I traveled through time more than once, but every time, it was an insult to my own conscience.)
