A few hundred years ago, Earth was affected by a mysterious force from the depths of the universe, triggering the revival of spiritual energy. However, things didn’t turn out as wonderful as humanity had imagined. The spiritual energy carried a strange power that caused the corpses of all living things to rise again, transforming into ghouls. And above these ghouls, even more terrifying beings existed…There were no ancient methods of cultivating immortality, nor any legendary awakenings of supernatural powers. But within the spiritual energy, there was also a presence of ghostly energy. This led to the emergence of Runes.Some people bore mountain runes, enabling them to move mountains and overturn seas, suppressing chaos. Others carried river runes, allowing them to reverse the flow of mighty rivers with a mere gesture. However, this process required a special profession to assist these rune cultivators—to constantly modify and engrave their runes, making them more refined and perfect.This profession came to be known as Rune Engraving.

The dimension storm has come, and there are a large number of different dimension fields in the earth.

Various immortal creatures such as immortals, Buddhas, demons, angels, and elves come to the earth. And those mysterious alien spheres have turned into copies of mobile games.
