Hundreds of millions of years ago, Emperor Fuxi exterminated the human race, demon race, beast race, other unknown races, and the rare dragon race for unknown reasons.
Shen Nong and Nv Hui tried their best to stop them, and finally... Shen Nong and Nv Huo died due to excessive consumption of power. Before their death, they injected their power into the Demon Feng Family, hoping that the Feng Demon Family could protect the continent. Pangu also placed a barrier to prevent the gods from entering the human world.
