That majestic voice was amused. "This old man has guarded the Netherworld Gate for more than three hundred thousand years. I have seen quite a few Earth Immortal Great Powers, and I even saw True Immortals back in the day.
"I have truly never seen anyone with a mouth as big as yours."
At those words, Wang Daoyuan's heart began pounding like a drum.
After staying here for over three hundred thousand years, even a pig should have cultivated into an immortal.
His own abilities were passable against ordinary Great Powers, but he would likely struggle against the very strongest ones.
Even the weakest Earth Immortal would not be much inferior to a top Great Power.
Judging by that probing attack just now, this old fellow should belong to the White Tiger lineage.
In an environment like the Ancient Battlefield, even the thinnest bloodline would have had enough time to purify over three hundred thousand years.
This fellow had seen True Immortals back then, so he had at least been a Great Power at the time.
After more than three hundred thousand years, he might now be a peak Earth Immortal.
If he could still maintain his peak combat strength, Wang Daoyuan could probably contend with him by inviting his master out.
The spiritual energy of the Seven Stars Sea Cultivation World had declined, so his cultivation might have regressed as well.
But even if a master who had once reached the Earth Immortal Realm had regressed in cultivation, all manner of methods at his disposal would still be utterly terrifying.
With Wang Daoyuan's little bit of ability, fighting him would only be delivering himself on a platter.
Xuanyuan was even more terrified. He no longer dared to play dead, instead hugging Wang Daoyuan's leg and trembling like a leaf.
