Basic Principles of the World of Immortality

Three thousand years ago, foreign tribes invaded, Zhongzhou was destroyed, the world was in chaos, the lineage of cultivating immortals was destroyed, and the civilization of cultivating immortals declined. Three thousand years later, a young man came into being and rose from the ordinary world. With the help of the heaven-defying treasure, he broke through the realm and helped bring order to the world. This is an old-fashioned article about cultivating immortals. The author pays attention to logic and rationality, and will give a reasonable social structure for the world of cultivating immortals. Why did spiritual stones become a common currency? Why are there so many spiritual stones that have been mined for tens of thousands of years? What is the purpose of the Immortal Cultivation Sect's recruitment of disciples? What does the sect's income come from? Why do some secret realm trials limit cultivation? Why are the ancient treasures, ancient methods, and ancient elixirs in the world of immortality more powerful than those in this world? What are the specific differences between each realm of monks? I am a new author who wants to write a slow work similar to the biography of a mortal cultivating immortality.
