Data Apocalypse, I Backed up All Human Civilization

The invasion of a cosmic-level computer virus called "entropy" causes the physical laws of the real world to begin to "digitize" and gradually collapse and disappear. Architecture, life, and even memory are constantly being "formatted". Liu Yishou is the world's top data architect. He designed the "Civilization Fire" plan to fight "entropy", but at the last moment he was betrayed by his jealous colleagues and bosses, taking away the results and leaving him in the data void that was about to be formatted. After returning from rebirth, Liu Yishou's brain merged with a "root directory USB drive". He was given "copy/paste" permissions. He can perfectly "copy" any real substance or concept (a building, a factory, a book of knowledge, a person's skills) that has not been completely eroded by "entropy" to the absolute safe zone of the USB flash drive. While others watched the city turn into gibberish and disappear, Liu Yishou was frantically "backing up" the world. He copied the National Library, the military-industrial complex, the super granary, the nuclear power plant... And even copied the "knowledge" of top scientists and the "skills" of fighting masters. In the data void, he used copied materials and technology to build a "new world" with stable physical rules and not affected by "entropy". Watching the enemies from his previous life killing each other for a piece of unformatted bread in the collapsing reality, Liu Yishou leisurely planned the restart of human civilization in the new world.
