Zhan Honglei and Zhan Fengyun gazed at the Immortal-Eating Gu filling the sky, their hearts sinking.
Especially when they sensed the Celestial Immortal aura radiating from the Immortal-Eating Gu's Source Gu.
There were also those seven golden Immortal-Eating Gu at the early Earth Immortal Realm.
Those alone were enough to threaten both their lives.
"Gu insects?"
"Although some of the Nine Heavens Hidden Clans excel at raising gu, none possess gu insects at the Heavenly Immortal Realm. Who exactly are you?"
"Could you be from the Gu God Sect on the Heavenly Origin Continent? Are these Golden Silkworm Gu?"
The Eternal Giants of the Nine Heavens Hidden Clans had long since investigated all the immortal cultivation factions on the Southern Heaven Continent and the Heavenly Origin Continent.
They knew perfectly well which factions could threaten a Celestial Immortal.
Zhan Honglei had never seen Immortal-Eating Gu before, so he mistook them for Golden Silkworm Gu.
He secretly communicated with Zhan Fengyun.
"They must have used a supreme-grade immortal artifact to seal off the space."
"From what I can tell, that blue-robed Earth Immortal Incarnation is controlling it. If I can kill him and break the spatial seal, I can escape back to Nine Heavens Star."
"Fengyun, for the sake of the Lineage, I need you to make a sacrifice..."
Zhan Fengyun's eyes widened as he glanced at Zhan Honglei in disbelief.
"Ancestor..."
Zhan Honglei sighed, his voice growing much heavier.
"You've seen it yourself. Among the spirit insects they control, one is at the Heavenly Immortal Realm, and seven are at the Earth Immortal Realm."
"If we fight them head-on, neither of us will get out alive. For the sake of our Lineage's survival, you should understand what you must do."
Zhan Fengyun nodded slightly, his expression turning resolute and grief-stricken.
