Radiation Is Coming, Human Beings Are Struggling

I am a novice and welcome your advice. Every suggestion you have will make me grow. This novel: no system + radiation + mutation + reality + home If one day the whole world is hit by a nuclear bomb, what will the world look like after the nuclear explosion? Is humanity destroying itself and ceasing to exist? Or will a new order form? What happens to the other creatures in this world? I hope the world is peaceful and that you and I can live in good health.
