The top-tier fighting forces Lin Fei currently had at his disposal seemed numerous, but few could truly shoulder the burden.
As for forces in the heavenly immortal realm—
The Immortal-Eating Gu Source Gu was in the early heavenly immortal realm.
Even with the seven Golden Immortal-Eating Gu in the early earth immortal realm and a million ordinary Immortal-Eating Gu added to its ranks,

Moreover, the Immortal-Eating Gu could not be exposed to the various immortal cultivation factions of the Heavenly Origin Continent.
