A world of spiritual cultivation with "contemplation of the heart lamp" as the core of practice and the fragmented laws of time. The universe itself is regarded as a huge source furnace of creation, which is divided into six major realms: the world of ordinary fire where living things multiply, the Danyun realm where spiritual energy transforms into rhyme, the cauldron heaven where laws are tempered, the realm of medicine where all things are used as medicine, the true fire without elixir that burns away all illusions, and the final source furnace of creation. By visualizing the mind, practitioners light the "heart lamp" and experience the six realms of concentration, mind wandering, everlasting light, reality, detachment, and freedom. They ultimately pursue "turning thoughts into reality" and turn the visualizations in their hearts into real laws. However, the ancient war caused the law of time to collapse, forming a "time fault" - abnormal areas where time stagnates, accelerates, flows backwards, and even parallel are scattered all over the world, becoming a dangerous situation where opportunities and despair coexist. The human race and the demon race in this world have been enemies for generations, and mixed blood is regarded as a taboo. The ideological conflict between the guardians of order who maintain the "orderly way of heaven" and the "order breakers" who desire to break all shackles constitutes the deepest contradiction in the world.
