Core concept extraction:
Core event: "The Inversion": The earth's physical structure undergoes drastic changes, and the earth's surface becomes a huge cavity wrapped in inner walls. Human beings are trapped in the "inner sphere" world between the earth's crust and the earth's core, with thick mantle rocks above their heads, and an abyss or strange geocentric landscape below their feet.
Core driving force: "Decalogue Array": a mysterious device left from ancient times, revealing the only way to survive - passing ten life and death trials from easy to difficult (the place of ten punishments)
Core setting: "Techno-Cultivation": In the end of the world when resources are scarce, humans use remaining technology to analyze the environment, assist survival, and transform the body; at the same time, through the challenges of the "Ten Punishments", they stimulate their potential and gain It is almost like "cultivating immortality" to improve abilities (body strength, energy control, mental power, etc.), But this improvement is not the aura of traditional immortality, but is based on the unique energy field of the earth's core (tentative name: "Earth Radiation" or "Essence Flow") and "regular evolution" that challenges the rules.
Core themes: survival and evolution, restart of civilization, test of human nature, rules and freedom, boundary between technology and "magic".
