Emperor Bai made it sound very simple.
In reality, even though the Tai Ying Soul Resurrection Formation and spiritual pool were both extremely helpful in the recovery of one's soul power, it was not easy to set up.
Tai Ying Soul Resurrection Formation originated from the ancient past.
At least ten masters of formation were needed to form this formation. Furthermore, large amounts of resources were needed to keep this formation running.
These resources could come in the forms of special power stones. However, unless the power stone was like that of the Supreme Emperor Stone, a large amount of these special power stones would be needed to keep the formation running. The Sanctuary Alliance could not bear such a cost.
Hence, Emperor Bai commanded around two hundred almighty to stay there at the Wushuang City.
They would provide divine power to keep the TaiYing Soul Resurrection Formation running.
