When I Woke Up, I Was the Only Human Being Left in the Universe.

When I woke up, I was the last human being on earth. There is no apocalypse, no war, just a sleep, and thirty thousand years have passed. For 30,000 years, my era has been buried under the grass and trees all over the mountains and plains. The earth has gone through a lot of changes. The earth is still the same earth, but it is no longer the earth I am familiar with. There are many aliens in this universe. And I am the only human among them. *Screenshot taken on 2021.7.27 *Inspired by the episode of "Stone Age" Purpose: Cherish life and protect the environment.
