In the face of the Corrosive Fate Dao, the starry sky has always been trying to find a solution.
Dividing the vast starry sky into segments as it is now was one such measure.
The first aim was to isolate the influence of the Dust Beasts, and the second was to experiment with different cultivation methods in different sections of the starry sky.
The goal was to foster beings that reach the Thirteen Realms and beyond.
Only those who reach the Thirteen Realms have the power to stabilize the starry sky's destiny, ensuring stability amid turmoil.
Corrosive Fate Dao's onslaught on the Great Tao River showed that only five sections including New Earth and Old Earth, which possess the Thirteen Realms, remain exceptionally stable, proving this effort worthy.
Even if they lack the capability to tackle the Corrosive Fate Dao completely, those reaching Thirteen Realms can still secure the basic situation to some extent.
