Infinite Flow of Apocalyptic Wasteland

Travel through the wasteland of nuclear war and inherit territory. But was messed up by someone who entered reincarnation? If it's a dragon, wrap it up for me; if it's a tiger, let me lie down! A reincarnator who has experienced countless worlds and has cruel methods? A reincarnator, with numerous enhancements added to his body, he acts without any scruples? In my world, Those who act recklessly shall be killed! Those who are angry and resentful shall be killed! Living in the apocalypse of a nuclear war wasteland, traveling through thousands of worlds, even though tens of millions of people have gone there, I will protect the last happiness of the wasteland.
