Resurrection of Spiritual Energy: Catalog of Demons

On a certain day of a certain month of a certain year, a national expedition team entered the Yeren Valley and brought out a bronze fragment. Then, with the Yeren Valley as the center, the plants grew wildly, and the animals went crazy and showed signs of atavism. Then, people who jumped several feet and broke stones with their bare hands appeared on various famous mountains. Although capable people and strangers appeared, their numbers were too rare. The global population was reduced by more than half. This year was the first year of the establishment of the Federation, also known as the first year of demons.
