Pick up the Planet at the Beginning of Doomsday

Doomsday + zombies + mutation + no rebirth + having a father and a mother + stocking up on supplies Is the earth's ozone layer being destroyed due to the influence of outer space rays, the invasion of foreign enemies, or is there another hidden reason? Zombie outbreak, global cooling, biological mutation, alien invasion. There are no reborn people here, no ability to predict things, just a migrant worker with a lucky start struggling to survive in the last days. Faced with the outbreak of various disasters, will people unite to overcome the difficulties, or will they lose their humanity and act recklessly? ... Let us witness the transformation of an ordinary character in the last days. I believe that there is no shortage of people in this world who are greedy for life and afraid of death, but there is still no shortage of heroes who die generously!
