1. The layout of the three realms: the mortal realm, the spiritual realm, and the fairy realm. The three realms are tightly guarded. You need to break through the realm or use special props to travel through them. The mortal world is divided into four continents, east, west, north and south, and the spiritual energy is thin. Only a few hidden sects and spiritual vein gathering places can cultivate immortality. The spiritual world is rich in spiritual energy and has many sects. It is the main gathering place for immortal cultivators and is divided into upper and lower realms. The immortal world is the highest realm, divided into nine heavens and thirty-six domains. It is home to ancient immortal clans and powerful monks. The power of laws is perfect and it is the core of the rule of the Immortal Emperor.
2. Cultivation system: Ordinary world (qi refining, foundation building, golden elixir, Yuanying, and divine transformation) → spiritual world (refining the void, combining body, Mahayana, transcending tribulations) → immortal world (earth immortal, heavenly immortal, golden immortal, Taiyi golden immortal, Daluo golden immortal, immortal king, immortal emperor). Each realm is divided into four levels: initial, middle, back and peak. The Immortal Emperor is the highest. Only one person can attain enlightenment and control the laws of the Immortal Realm.
3. Core rules: "Dream World Linkage" - The protagonist Lin Chen has an innate "Hongmeng Dream Seed" in his body. After falling asleep, his consciousness can enter the phantom of the fairy world with a flow rate of 1:1000 compared to the real time. The skills, insights, and opportunities practiced in the phantom can be synchronized to the real body. However, the injuries sustained in the phantom will have a weak backlash on reality (can be resolved through elixirs). Dream seeds need to be nourished by spiritual energy. The higher the realm, the stronger the stability of the dream. In the later stage, you can actively control the timing of dreaming.
