I Picked up a Book of All Realms

Lin Yi picked up a wordless book. Knowledge from other worlds—future technology, lost techniques, and magical formulas—will randomly appear in the book. Relying on these, he changed from an unemployed youth to a genius in the eyes of others. But he soon discovered the price: every page of knowledge came with a "copy". The original owner of that knowledge—an individual with independent consciousness and the ability to independently generate new knowledge—will be completely copied into his world. Some of these clones just want to do research, some are crazy and want to go home, some want to be kings and hegemons, and some don't even know that they have been cloned... The book was in Lin Yi's hand. He is the only anchor. But he doesn't know who will help him and who will harm him. And as more and more copies arrive, the concentration of spiritual energy in this world is quietly rising. Martial arts reappear, technology changes, and an unprecedented era is about to begin.
