This is a dark age, the world is like a melting pot, where immortals, Buddhas and demons all want to refine a "supreme elixir".
Humans are like ants who live in vain. Instead of seeing gods when they raise their heads, they see butcher knives stained with blood.
Immortals and Buddhas fight with each other, and mortals become chess players, while demons and ghosts cause harm to the world.
If the immortal doesn't save the Buddha, he won't say anything. A kind word will end the matter.
After the Nine Expeditions, Li Xiuyuan vowed to return the world to a bright and prosperous world.
