Chapter 1: After the Apocalypse.

Short Summary:

After falling asleep, the protagonist unexpectedly finds himself transported to a post-apocalyptic world, which happens to be the setting of a famous game on Earth.

Unfortunately, he doesn't possess any overpowering skills like the characters in other reincarnation stories. In fact, he is even weaker than the average person in this new world.

However, thanks to his innate intelligence, he discovers unique ways to survive in this new environment.
