Refining the Deduction

As for having the cultivators of the Yingzhou Immortal Island Lineage spend more time and effort operating the Heaven-Earth Origin-Returning Formation?

There was no longer any need for that!

If hundreds of millions of Golden Immortals and Taiyi Golden Immortals participated in operating the Heaven-Earth Origin-Returning Formation, then whether the cultivators of the Yingzhou Immortal Island Lineage spent a little more time and effort would no longer matter.

Aside from the considerable number of Great Firmament Golden Immortals, Quasi-Sages, and Primordial Golden Immortals needed to guard the crucial formation foundation nodes, the Taiyi Golden Immortal cultivators of the Yingzhou Immortal Island Lineage...

Should not be sent to operate the Heaven-Earth Origin-Returning Formation. Instead, they should be deployed to guard and manage the cities throughout the Western Continent.

Basically, one Taiyi Golden Immortal per city would be enough.

Although the Taiyi Golden Immortals of the Yingzhou Immortal Island Lineage might not have reached Taiyi Golden Immortal Perfection and might not be a match for the Taiyi Golden Immortal cultivators entering the cities.

They would be within the cities, where they could activate the grand formations laid out there. With permission, they could even draw upon a trace of the Heaven-Earth Origin-Returning Formation's power. As long as their opponents were not Great Firmament Golden Immortals and had not formed a grand formation, no number of Taiyi Golden Immortals could stand against them.

A single Taiyi Golden Immortal would be enough to deter the Golden Immortals and Taiyi Golden Immortals entering a city.

As for management?

A Taiyi Golden Immortal could easily split off a large number of Profound Immortal avatars. They could completely divide off many Profound Immortal avatars to help manage a city and handle its many affairs.

Of course, if they found that too troublesome and detrimental to their cultivation,
