Ordinary people, after death, if their bodies are not cremated, a part of them will become nourishment for nature, fostering a piece of the natural soil.
However, for cultivators, after death, a portion of the spiritual energy within their bodies will also disperse into the world.
The stronger the cultivator, the greater the amount of spiritual energy their corpse will release upon their demise.
It is just like the Land of Celestial Tears, which is entirely influenced by the bodies of immortals, hence forming a terrain so rich in spiritual energy that it possesses lethal force.
At the pinnacle of the Integration Stage, although comparing to true immortals is like comparing heaven and earth, the spiritual energy released from their corpses is still more than enough to nurture an Emergence Stage cultivator with ease.
