There was a valley in this world called the Night Valley. It was the darkest place in the world. At every moment, a large number of vengeful spirits grew. They were densely intertwined and formed powerful vengeful spirits like Gu. Once the strongest left the valley, they could even destroy all the living beings in the world.
But in the deepest part of the valley, there was an unremarkable natural grotto, in which there were a few pieces of furniture made of stone placed casually. This was the holy land of all the Luminarists. After every expert who had reached the nine-star Life Lamp died, their souls would return to the hall and light their own longevity lamps.
Ever since the beginning of the world, there were more than 80 longevity lamps floating in the cave, which meant that more than 80 experts of the nine-star life lamps had fallen.
