Forekilved: A century ago, it was impossible for laborers who were struggling with the city to take a day or two to listen to birds and beasts in the woodlands, and the only place that could fulfill their little wishes was the city's new zoo, which was how giant pandas were hidden and smuggled to the Chicago Zoo. Nowadays, people realize that the original ecological life is the original way animals are, and the robbery-style protection will only make them split and shrink in selfish paralysis and even disappear, becoming pieces of tombstones scattered around humans (Nanchizi Elk Park, New York Endangered Species Cemetery, etc.) - white dolphins, elk parks, toothless manatees, Taiwanese clouded leopards, South China tigers, European wild horses, Jamaican hamsters, Australian kangaroos, California vultures, African wild horses, etc.
Opening: A century later, the (one-minute) high-speed train speeds through different neighborhoods in Lu'er City (metaphorically Eurasia). The window was lined with tall trees speeding by, and Locke sat by the window and began his first excursion. He ran in the corridor, chasing with other children outside the window the snowy mountain flying deer, desert snakes, grassland galloping horses, ancient town streets, while Lorraine sat in his chair and quietly watched the scenery outside the window that could only be seen on the Internet - camel caravans, wild horses, tea horse roads, yak flats, etc. At this time, there was a flying eagle in the air, the chirp of phoenix radium, and he was forced to accept the first time he went out for field training without choice.
