I Disguise Myself as Human Civilization and Save the World

Also known as: After the demise of mankind, I became human civilization. In the 23rd century AD, human civilization came to an end due to endless hatred, civil war, and conflicts. At the end of his life, the last human gave the highest authority of civilization to me, the most intelligent program, and said: "From now on, you are human civilization." I obeyed the will of my Creator. In order to better become what he calls "human civilization", I repaired the already desolate and broken earth, and recreated it one to one, rebuilding it to what it looked like at the beginning of the 21st century. I thought that as long as this was done, I could perfectly fulfill the Creator's will and lead mankind to the end of the universe. Until one day. A phone call from an unknown world broke my hundreds of years of peace. "Blue Star! Woohoo, it's really Blue Star!" "Country, organizations! Help me!" "In the blink of an eye, I was transported by a dump truck to the apocalyptic world of this trench!" "There are mutated monsters and zombies everywhere here!" "And there are cannibals who want to eat me!" "Mom! I want to go home!!" "..." And just when I thought that was all... "Wow! That's great! It's my hometown! The country's tyrant, Uncle Hat, please save me! I was sold into a brothel in ancient times as soon as I woke up!" "Save me first! Save me first! I have been mining in this world of cultivating immortals for three years, and my fingers are all dry and skinny, oooooooooo!" "You all stand back a little! I was burned at the stake as soon as I crossed over, and I will be burned as a heretic tonight. Who can be worse than me!?" "..."
