"Wealth, companions, land, and methods."
A wisp of chaos mother qi appeared in Li Xian's hand, and he refined it into his world.
After a Mysterious Immortal finished opening up a world, they had to continue strengthening its internal yin-yang and five elements and completing its spatial framework, while also refining treasures containing the Dao resonance of their Great Dao into the world, allowing that Great Dao to grow and better support it.
