- Description from novelupdates

By accident, Lu Zhiyu found the entrance to a low-dimensional world, and thus began a totally different journey!

The bad news, at least for me, is that I died. The good news is that I was reincarnated into someone else's body who lives in a cult full of beautiful women... but this cult forbids love. Well, one can't have all the good things. I thought I was safe until the worst happened. A system appeared that told me that I would die if a girl didn't accept my confession within a month... I have to get out of that cult now.Every 10 days I upload 15 chapters at once on Patreon.

In the distant future on Earth, there was a girl with God-like powers. That girl is the last survivor of the former human race that flourished in ancient times.

The Ancients.

And on that very same Earth, a new breed of humans with the ability to wield Magic emerged.

That girl began to observe the new human race silently.

Sometimes called a God, other times called Satan, that girl continued to observe the new human race.

This is the story of the happenings between the lonely girl and the hardworking new human race.
