Aside from the Earth Immortal Ancestor Zhen Yuanzi, Yun Xiao, who achieved the Primordial Daluo Golden Immortal status through Array Dao, also returned to the Primordial World under Xuanqing's arrangements.
Zhen Yuanzi was responsible for refining the Primordial Earth's Veins, while Yun Xiao, due to her expertise in Array Dao, was responsible for transforming the 'Universe Refining Heaven Array' into a 'Space Migration Formation' to relocate the Primordial World.

The two had no sooner returned to the Primordial World than they began to urgently draft a migration strategy.
