Please recommend a transmigration novel with a knife-throwing theme.

There was a plot in a time travel novel about throwing knives. The main character was on the street and met an assassin who wanted to assassinate the princess. However, he was also in trouble. He had no choice but to throw a throwing knife. The throwing knife technique was impressive, but his own strength was too weak, so he could only pretend to be dead. The assassin was blocked by the throwing knife. He felt that this throwing knife was sent by a very impressive person. However, he did not show himself and was scared away. He died and forgot about it. Then, the woman was saved. He felt that this throwing knife was very exquisite and was grateful, so he kept it. He held a knife all day long and let his imagination run wild. There was even a chapter title called Flying Knife. Seeing Flying Knife Again... It's not a flash
