Rebirth of Doomsday Disaster

If mankind is destined to perish, why would I be reborn here? Why are zombies still besieging the city and alien species covering the sky? Since God has given me another chance, even if I reach the heaven and earth, I will lead the unyielding mankind, overthrow everything, conquer the world, crush the doomsday, and reach the end. How will the brilliant boy thrive in the apocalyptic disasters, evolve his powers step by step, destroy the conspiracy layer by layer, and travel with the beauty again and again? Look at me, I can call the wind and rain, and reverse the destiny of heaven. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
