I recommend the two novels,"Fleeing from famine at the beginning of transmigration" and "The Jade Space of Doomsday". They were all sci-fi space-futuristic worlds. The protagonists had a portable space, survived in the apocalypse or traveled to ancient times, and used the ability of space to help themselves survive and develop. I hope you like this fairy's recommendation. Muah ~😗

I recommend "The Fortress of All Races in the Global Evil Land" to you. This novel is a sci-fi novel about evolution and mutation. The protagonist, Sheng Ziyou, wants to break out of this reincarnation in another world and gradually develop a new civilization. From the first sprout underwater to the giant beasts of the Stone Age, from the dazzling magic to the flashing neon lights on the streets, the times were changing and the power was changing. And civilization was a cycle…Just look at the future Fei Ling, it would definitely be a world of all races! I hope you like this fairy's recommendation. Muah ~😗

One example is 'The Great Gatsby'. It goes back to the Jazz Age, showing the glamour and decadence of that time period.

" Campus Rebirth: The Exorcist Girl "

There were many novels about going back to the past. However, according to the information provided, I recommend a novel about urban life to you,"Return to the Past: The Spring and Autumn of the Siheyuan." It was about a modern man who had retired from the army and returned to the courtyard house ten years before the official opening of the game. He wanted to write his own story. I believe that this novel will bring you a wonderful experience of going back to the past. I hope you like this fairy's recommendation. Muah ~😗
