Seven billion humans living on the Earth time-traveled together after they had woken up one morning. They all heard a synthesized female voice.

At the beginning of the universe, there was only chaos. Chaos gave birth to a world, accumulating into Black and White and the five elements (also known as the Origin Elements), creating the world's laws and the order of heaven and earth.

This world was called the Origin world, where the Original beings born out of chaos reigned. They created orders, creatures, and numerous worlds where they reigned as Supreme beings until a calamity befell them and destroyed the Original world alongside numerous worlds.

Two billion years have passed since then. In a small world somewhere, a baby was born carrying an unusual past.

You thought being reincarnated as an extra-side character was bad? Imagine being thrown into the body of a villain who is disowned by his own family and discarded by the author.
