Travel Across the World

With so many people traveling through time, why is it that only the protagonist survives and can summon generals to conquer the world? "A man made a bird-like thing out of a big piece of paper and said it could fly. But when he got up, he fell down and died." "There was also a man who made something called a bicycle out of wood. Unfortunately, it fell apart after a short time. The emperor chopped him down in anger." "There is another person..." Before the young man finished speaking, Liu Bin immediately said: "Stop, stop, stop! You said so much, isn't there anyone who survives?" "Yes, there was a woman who traveled through time. She slapped the emperor, saying that he would fall in love with her." "What's the result?" Liu Bin asked immediately. "As a result, the emperor was furious and sent her directly to a brothel."
