Time Man: Go Back in Time and Rob the Ruthless Emperor

I, Li Xianyu, am the strongest robber in all time! When I woke up, I became the keeper of the long river of time. No matter you are a time-traveling protagonist whose luck is against the heavens, or a supreme emperor who intends to reverse the cause and effect, if you want to cross this river, you must first pay the money to buy it! I snatched the golden finger from the protagonist, received the money from the emperor, and became the richest man in the world through robbery. I thought that life would always be so simple and boring, until that day, a white-clothed empress wearing a ghost-face mask came on a boat. "Name?" "Ruthless person." "Purpose?" "Go to eons ago and save people." I closed the notebook and gave her a professional smile: "You can save people, but first hand over the toll - your "Swallowing Heaven Demon Technique"." She cut off the eternity of time and space with one sword, and I lightly snapped my fingers. The entire river of time... Frozen for her at this moment.
