Stone Era: Restarting Civilization

The order of the world may be subverted at any time.

For example, the abuse of antibiotics has caused gene mutations, or an extremely deadly influenza virus has been artificially created. In the face of this virus, if humans do not develop an antidote, the world order will collapse.

Or because of various interest entanglements, human beings break out of war, and after a powerful ultimate weapon is put in, the world order will collapse.

Or if an asteroid with a diameter of one thousand meters hits the planet we live on, the world order will collapse.

Or, in the sky, a green light like the eyes of Medusa appeared, and everyone instantly petrified.

Welcome to the world of Stone Age, where the world order has collapsed.
