[Traveling Overhead History] People living in 3030 have exhausted the shortage of contemporary resources. They have exhausted all materials and developed a machine that travels through time. They hope to find someone, that is me, to travel back to the past. Warn the people in the past to cherish all kinds of resources and not waste them, otherwise, their descendants will have difficulty surviving in the future. It was originally planned to travel to 2000 AD, but one person's carelessness directly made me travel to 2000 BC. I actually traveled directly to the Xia Dynasty. I wanted to wait for a long time, but later, I decided, I want to start now! Ordinary literature I want to let me live in the future, full of resources! Inexhaustible and inexhaustible! I want my friends, brothers, to stop living a life of begging. I want to start working hard from now on! I may not live long here, but instead of waiting to die, it is better to start now, right now.. .
