Immortals become gods when they have a position. Gods use their authority to collect cultivation resources to achieve faster and greater improvement. However, the energy is balanced. The more people practice, the faster the resources are exhausted. The gods who have achieved great supernatural powers in the first step use powerful means to forcefully control the largest and richest areas. The realm was separated from the fairy world and designated as the divine realm. The rules of the fairy world were changed, and the energy required for cultivation was divided into two qi of immortals and demons. Space barriers were set up, so there were two realms of immortals and demons. From then on, it was almost impossible to become a god. Only when the two qi of immortals and demons were balanced and integrated in the body could one break through. But compared with the vast void, the worlds of immortals and demons are just a drop in the ocean. A pair of ordinary brothers have gone through all kinds of hardships. From the mortal world to the world of cultivation, one becomes an immortal and the other becomes a demon. Can they finally break through the obstacles set by the gods? Can it finally solve the problem of energy depletion?
