Weird Invasion, I Can Go Back Infinitely

Despair + horror + brainlessness + apocalypse The protagonist has a golden finger, but he does not collect supplies like traditional apocalyptic novels. He has cool points, but he is not brainless. He does not push and enjoy all the time. Instead, the protagonist uses the golden finger to survive in this desperate apocalyptic world (the world view of this book is a fictional world and does not involve facts)
