Humanity Has Perished, How Can I Revive It?

I came from another world, but became the last human being in this universe. In the wandering space city after the demise of mankind, I stood on a pile of bones and looked up at the stars. Machines and monsters roared in front of me, and gods and demons whispered in my ears.

As long as I study hard and successfully pass each exam, I can conquer the endless starry sky!
