Rules: Collapse, Reorganization and Rewriting

Alternation of old and new rules Is it an opportunity? Or a disaster? In the face of force majeure and powerful factors, humans at the top of the food chain seem to have returned to ancient times, panicking all day long. Something called the Source Core appeared and changed the entire world. It is to stick to your heart, even if you have no power to restrain the chicken, you must stick to the future of mankind, and believe that everything will eventually pass and the world will return to its original appearance. Or is it assimilated by the core of the source, and all diseases will be eliminated from then on, getting rid of the cycle of birth, old age, illness and death, and becoming a more "advanced" life form? No system, no cool writing.
