Humans are adept at making use of tools, and have created many legendary treasures. They use these artifacts to strengthen their bodies and make up for their shortcomings.
Demons have powerful bodies and violent natures, but they enjoy long lifespans.
Humans call spiritual energy "gai." In modern scientific terms, it is actually made up of volatile particles. Stable atomic nuclei do not emit particles and are not radioactive, while unstable nuclei emit particles and are radioactive. Thus, nuclear weapons can deal devastating blows to demon beasts.
Cultivation progresses through Qi Refining, Foundation Establishment, and Golden Core.
The strong prey on the weak. This is the law of the world.
At its core, cultivation means making the human body compatible with spiritual energy: removing its repulsion and turning that energy to one's own use. But spiritual energy itself carries the laws of the world, so one must cultivate a calm and balanced mind. This is why Daoists shun the world, and why the more powerful a cultivator becomes, the more heartless they are.
The weaker demon clans are cruel and bloodthirsty because they lack intelligence. In an environment filled with spiritual energy, they are influenced by it and act on instinct.
When Nuwa repaired the heavens, she used her immense power to isolate the world from spiritual energy. But a world cannot appear from nothing. Spiritual energy can be shut out, but the materials used to create the world itself are saturated with it. As time passed, most of it gradually dissipated. What remains includes certain unusual elements found today: some are radioactive, while others are extremely stable. The differences between the elements are caused by differences in the kinds of spiritual energy. By studying these differences, the demon clans and ancient cultivators can comprehend the Three Thousand Great Daos.
