After a day's adventure in the kingdom of history, periods, question marks and exclamation points escaped from the dictionary castle. I'm going to leave 2 1 century and take risks in the historical kingdom. Period and question mark take the exclamation point space-time plane and dive into Cretaceous Park. There are many dinosaurs there, all kinds of them, just like dogs in pet shops. Dinosaur gentlemen bowed their heads and kowtowed when they saw the UFO coming, to compete with the punctuation marks of the new era! The competition between the old and the new era has begun. Pterosaur became an air announcer. "Ready, let's go!" The exclamation point is given. The question mark threw the period hooked on the body outward, and the period rolled back and forth on the ground like a ball, and then gradually became bigger like a balloon, pushing the dinosaur to the top of the hill. When the pterosaur looked unconvinced and was ready to peck at the full stop, the clever exclamation point immediately turned into an empty plane, taking the full stop and question mark into space. Hasty punctuation allowed an asteroid to collide with the earth, which may have led to the extinction of dinosaurs. Just as the expert question mark criticized the naughty bag, the space flight of the exclamation mark opened the space-time device, which was Newton's youth. An apple was thrown out of the exclamation point space-time plane, and it landed on Newton's head, letting him know the attraction of the earth. Many years have passed. Now, the owner of the dictionary bunker has locked them in the dictionary castle to punish the period, question mark and exclamation point that made the dinosaurs extinct.
