Jiang Ming had learned about the division of cultivating realms here in Luo Heng's world. It was basically divided by the planet.
On the planet were apprentices of up to grade nine Warriors. It was corresponding to the ten realms of the mortal world where Jiang Ming came from. After the Grade nine Warrior was followed by level Planetary, Stellar, Galactic, Star River, Star Field, Star Sea, Cosmic, and Supreme.
Based on Luo Heng explanation, and the condition of the Supreme Chat Room, Jiang Ming calculated that level Planetary, Stellar, Galactic, Star River, Star Field, Star Sea, Cosmic, and Supreme were corresponding to Heavenly Immortal, True Immortal, Mystical Immortal, Golden Immortal, Taiyi, Great Overarching, Quasi-Sage, and Saint respectively.
