Earth Adventure

My name is Tang Wenxuan, and this is my second visit to the earth. When I first came to the earth, it was full of giant animals, which modern earthlings call dinosaurs. And I came to this planet again when I was in the Tang Dynasty. Now I have lived here for more than a thousand years. Just yesterday, I received a message from my home planet, and it was sent to me by my superior. The content is to ask me to write a detailed report about the event 66 million years ago.

Galaxy Calendar: 3500 years Earth's Chronology: End of Cretaceous Period At this time, in the solar system, it is located in the asteroid belt between Jupiter and Mars. Several small transport spacecrafts were constantly changing their formations, sometimes lining up in a straight line and passing through the asteroid in front. Sometimes they spread out, avoiding the asteroids ahead alone.
