This is a unique world where "spiritual energy burns". The spiritual energy of heaven and earth does not gently nourish all things, but periodically erupts like wildfire "fire of spiritual embers", burning all things. The ancient power set up a "spirit-suppressing formation" for this purpose, transforming the violent spiritual energy into a form that can be absorbed smoothly by the monks. However, the formation has gradually declined after thousands of years, and the world is quietly slipping to the edge of the next spiritual ember cycle.
