We Promised to Go Back to the End of the World, so Why Did We Come to Chronicle It?

Tian Yi, a man who has lived alone for five years in the apocalypse! I have awakened my spatial powers, but I still live alone. Being attacked by others, we chose to die together! Unexpectedly, he returned to before the end of the world. He used the property in the space to buy supplies and actively prepared for the end of the world! But what he didn't expect was that the end of the world he thought had not come. On the contrary, he returned to the 1970s! An era that is both open and conservative! See how he survives in this age where he only learns from books! He does things that he didn't dare to do before, he says things that were difficult to say before, and he beats people that he didn't dare to hit before! This book is pure nonsense. If there are any similarities, you are considered awesome!
