I Am the Only One Who Can Conquer the World with One Sword

My name is Lin Chuan. One night I saw two gangsters committing murder on the street, trying to rob a female college student. How could I tolerate such a thing if I was upright, so I rushed forward to fight with the gangsters, and was accidentally stabbed in the vital part. Before I died, I saw the gangsters running away, and the person involved was safe and sound, so I closed my eyes. When I opened my eyes again, I was reborn into a fantasy world that can only appear in novels! ! !
